F-35 Was NOT Inferior to F-16 in a 2015 "Dogfight"

Why Any Inference that the F-35 2015 'Post-Stall Agility' Control Law (CLAW) Test As a 'Dogfight' is Bogus

This is a rework of something I posted on twice in 2015. I'm doing the rework a a form of blog 'housekeeping'. When I wrote about it in 2015, the focus was on the echo-chamber, click-bait media claiming or inferring the CLAW test was a 'Dogfight' test. When I look back at that post, I now feel I buried the lede twice. The important bits were not how media tends to be F.O.S. for all their shenanigans (that's hardly 'news'), but the reasons WHY it was not a 'Dogfight' test, and that it can be clearly shown it was NOT a 'dogfight' test are.

Nowadays that the 2015 'controversy' seems to be a perennial word-count filler: something for the lazy media to put in a piece to 'balance out' any positive information about the F-35 in any article or story that might appear to be otherwise 'favoring' the F-35. I want to be very specific in what I am claiming going forward.

Assertion:  The event in question was a post-stall agility test, testing for areas where it might be worthwhile to 'open up' the control laws (CLAWs) and was not a 'dogfight'.

The 2015 Testing in Question was Described in 2014

Supporting Evidence:
The JSFPO and Lockheed Martin at the time of this faux controversy asserted it was a CLAW test. The assertion was met with much snark and derision from the professional cynics and F-35 Haters, yet that is exactly what the test was about. and it was described in a published technical paper by an LM engineer who should certainly know WTF the test was going to be about at the time he wrote the paper.

From the 2014 AIAA paper "F-35A High Angle-of-Attack Testing"[1], by Mr. Steve Baer, (Lockheed Martin "Aeronautical Engineer, Flying Qualities" at Edwards AFB), and presented to the Atmospheric Flight Mechanics Conference held 16-20 June 2014, in Atlanta, Georgia we find that F-35 High AoA testing was designed to follow in the following progression:
 "The test objectives for high angle-of-attack testing are as follows: 1) Characterize the flyqualities [sic] at AoAs from 20° to the control law limit regime with operationally representative maneuvers. 2) Demonstrate the aircraft’s ability to recover from out of control flight and assess deep stall susceptibility 3) Evaluate the effectiveness and usefulness of the automatic pitch rocker (APR) 4) Evaluate departure resistance at both positive and negative AoA with center of gravity (CG) positions up to the aft limit and with maximum lateral asymmetry. 5) Assess the handling qualities of the aircraft in the High AoA flight." 
Let's observe here that from the paper itself we can tell it was written while Objective #4 testing was ongoing and published at about the time it concluded. This observation is supported by the paper's passage [emphasis/brackets mine]:

With intentional departure testing [Objective #4] wrapped up, the team will soon move into departure resistance [Still Objective #4] and plan to remove the SRC now that these systems have been verified. In this phase of testing, the jet will test the CLAW limiters with much higher energy and rates than previous testing, fleshing out and correcting areas that may be departure prone. Lastly, select operational maneuvers [Objective #5], such as a slow down turn and a Split-S, will be used to gather handling qualities data on high AoA maneuvers. With the completion of this phase, the F-35 will be released for initial operational capability in the high AoA region. 
Note: 'SRC' is a 'Spin Recovery Chute'. 

Clearly the testing was not yet at step #5 at the time of writing but to emphasize same, the author followed the above paragraph with [brackets/emphasis mine]:
While the flight test team will explore legacy high AoA maneuvers for handling qualities, it will be the Operational Test and Evaluation team that will truly develop high AoA maneuvers for the F-35. In the operational world, a pilot should rarely be taking the F-35 into the high angle-of-attack regime, but the ability to do so could make the difference between being the victor or the victim in air-to-air combat.... 
So with this paragraph, not only does the author expound on the exploring of "legacy high AoA maneuvers" that is to come, he specifically identifies Objective 5 test as having "Handling Qualities" objectives and explicitly states that the kind of testing that will "truly develop high AoA maneuvers for the F-35" to the testing Operational Testers will perform later and excluded from the Edwards AFB Developmental Test Team activities.

In a nutshell, just within these two paragraphs that Baer wrote in early/mid 2014 is precisely what the JPO/LM stated in their official response to claims that the 2015 event involved some kind of 'dogfight'. Therefore the "reasonable man" may logically and confidently conclude the LM/JSFPO response:

1. WAS NOT simply something that was contrived in response to stories built around leaked program documents but...
2. WAS accurately asserting the truth about what the testing purpose truly was.

Now here we are two years later...


By next year and the roll out of '3F' software/capabilities I doubt if you will be able to find an F-16 pilot who has flown the F-35 that would not pick the F-35 over the F-16.

“Fighter Aircraft” Design: Driven by Operational Requirements (Part 3)

With the world about to bear witness at the Paris Air Show (#PAS17) this week that the F-35 is NOT the 'pig' aircraft that the propagandist critics (all of whom have NO material knowledge of the F-35) have claimed, I decided it was time to finally publish this post and close out the series. All the contrived elaborate and ignorant ‘stories’ assembled from twisted factoids  that have surfaced over the years, are about to fall flat, and will trigger much denial, wailing and gnashing of teeth from those quarters.
Now is also an especially good time for me to close out the series because it will be a handy reference for later smacking down a piece of anti-JSF Dezinformatsia that surfaced (as a metaphorical rotting dead cetacean) this week.

Behold! O haters and doubters.....and weep.

Super-manueverability without Thrust Vectoring, Check...

And so we proceed…

The entire point of this series has been and is to illustrate that fighter design isn’t driven by opinions, whim, or fashion; nor is the implementation of it either the least bit capricious. To recap, Part 1 of this series was just an initial outline of what I intended to cover/accomplish overall. Part 2 was an extended ‘two-parts in one’ review of the evolution of fighter design requirements from the earliest days and up through the emergence of ‘supermaneuverability’. We reviewed the developments that influenced fighter designs up through to the ‘fourth-generation’ of fighters and we could even say included design trends that influenced the earliest aerodynamics of fifth generation design: the F-22.

This brings us up to the starting point for Part 3, still somewhat in the past, but not so far as to prevent us from getting to the present from there. In the introduction of this series, I had originally envisioned that in Part 3 we would:
..."break down a 1 vs. 1 air combat scenario into a high-level conceptual model of constituent phases and associated combatant states. Then we will apprise the F-35’s potential advantages and disadvantages”...
As it turns out, we can leverage one and a half decades of expertise from professionals to accomplish the first objective and do so in fewer words than I had initially planned. We will also use the same for framing the discussion to meet the second objective: quickly ‘apprising’ the “F-35’s potential advantages and disadvantages”. It should shock only those with less than a passing interest in, and/or superficial knowledge of the subject, that by the time the first Part 3 objective is met, the second objective will become largely self-evident.


“Aircraft Maneuverability” or “Agility” research probably reached its zenith (in the West anyway) with the extremely successful X-31 Enhanced Fighter Maneuverability Demonstrator program.

Before the X-31 even flew, it was already viewed as a key investigative tool for ‘applied agility’ research, and the only effort at the time to span all “applied” research areas of interest.

Figure 1. X-31 Spanned Applied Agility Research Interests

I was TDY to Edwards AFB for one program or another and we had just landed (it had to have been sometime in 1992 or January-ish 1993 at the latest) and while sitting on the ramp waiting for a crew van, we watched the X-31 return from a mission and work the pattern with its chase plane. The discussion, led by our own test pilots and flight test engineers, turned to wondering: Just how much any additional maneuverability that might come out of the X-31 program would actually translate into any REAL additional combat capability? This is a question of the same kind of ‘asymptotic limits’ that were addressed in Part 2.

As it turns out, we still can’t quantify an answer to that question because nothing about that time on up through to the present day was, or is, “static”. Changes and developments in all the other fighter aircraft capabilities and technologies kept evolving long after we hit peak ‘supermaneuverability’ with the X-31. But from Part 2 and what we are about to review, we can answer the question in general:
1) Maneuverability beyond the F-16/F-18 characteristics doesn’t really get you all that much more capability (effectiveness and survivability), and  
2) When costs involved are considered, there are cheaper/better ways to increase combat offensive capability and survivability than improving AoA, turn rates, or g-loads past the present state of the art.
We know these are the answers because those involved in fighter design and development have known them for a long time. From 1986 through at least 1995, the NATO member countries of France, Germany, the United Kingdom, and the United States collaborated on a major study1 to determine where future fighter design efforts should be targeted.

Note:  
While I’ve been too busy to engage in substantial posting for a lot of reasons, another reason this post was so long in coming is the open source data has been fickle. I first typed out about 4K words (longer than this post) I had put to electrons just to go over the gory details in the study we are about to discuss. But after all that work trying to do justice to the contents of the study I found a copy of the original without a paywall in place. I slashed what I had written to leverage the source without saving the earlier version. Then the source disappeared again. If access reappears, I'll link to it.


The study had two major objectives:
• Through analysis and simulation, determine whether supermaneuverability is operationally useful in future air combat scenarios.  
• If operationally useful and technically feasible, determine the practical limits of supermaneuverability and full envelope agility.

The context of the study was obviously about the benefits of supermaneuverability in WVR combat. The authors referred to it as “Close In Combat” (CIC), of which choosing to engage in a turning fight is only one possibility. After all there’s not much point in doing a Danse Macabre if there’s no opponent within visual range to ‘appreciate’ it.

The study participants used the following definitions:
“Supermaneuverability is defined as very high levels of maneuverability and agility throughout the flight envelope of a fighter aircraft, especially beyond maximum lift.”  
“Agility is defined as the ability to change states rapidly with precision.”   
“Full envelope agility contains airframe, missile, and avionics attributes.”
It is important to observe here the recognition by the actual “experts” involved that the broadest definition of agility was important going in to the study. The definition of 'weapon system agility'  has become a somewhat standard one:

Figure 2. Weapon System Agility = Total Agility
(See also my backgrounder on modern Energy-Maneuverability,)


The study’s ‘statement’ of purpose was:
Previous analyses and manned simulations for close-in-combat (CIC), primarily emphasizing 1 v. 1, have indicated substantial improvements in air combat effectiveness when supermaneuverability (in particular, post-stall technology) was incorporated in advanced fighter designs. Recognizing that air combat scenarios are likely characterized by rapid transition from beyond-visual-range (BVR) to CIC involving multiple aircraft, the effect of supermaneuverability technologies on the outcome of this type of engagement needs to be determined.
This multi-national NATO-sponsored study began with manned simulation at Industrieanlagen-Betriebsgesellschaft (iABG), involving two piloted aircraft and three computer generated aircraft. Four pilots were trained on the baseline post-stall aircraft including avionics, weapons, and scenarios. After the training phase, the pilots jointly determined possible starting conditions (geometry, speed, weight, weapons load, number of runs, etc.).
The purpose of the manned simulation was to create a database to develop a digital pilot reaction model. The application of a batch model was necessary in order to generate the large number of computer runs needed to accomplish the project goals. The batch simulation strategy involved three different programs. First, the ‘Arena’ war simulation program was used to model a beyond-visual-range, many-on-many air battle and generate within-visual-range starting conditions. This was a valuable technique that got the study group past the ‘How do we set up realistic WVR combat starting points?’ question. Second, the Air-to-Air System Performance Evaluation Model (AASPEM) was used to model one-versus-one (1 v 1) engagements that were initialized under the Arena-derived starting conditions. Third, the Abductory Induction Mechanism (AIM™) was used to link AASPEM results to Arena as depicted in Fig. 3.
 

Figure 3. Source: Practical Limits of Supermaneuverability and Full Envelope Agility

As you can see by the parsing of function among different models, it wasn’t easy to do complex scenario modeling back in the 80’s-90’s. The primary models had to be linked because neither one could answer the questions ask if used as standalone devices. An evolved MIL-ASSPEM II was part of the USAF’s standard analysis toolkit as late as 2005. It might still be.

The study identified and used probability of kill, probability of survival, and exchange ratio as “the key parameters” using two types of weapons: missiles and guns. For each weapon type they assigned a probability of a kill (Pk) given a ‘hit’. Under a ‘massive-number-of-trials’ modeling effort, they established an average Pk of a (AIM-9L ‘like’) missile of 0.8 for each simulated missile fly-out. The Pk (given a ‘hit’) of the missiles being held constant may have made some of the long-term study quantifiable results more conservative ‘offensively’ and more optimistic ‘defensively’ than optimum, given the lethality enhancements seen with AIM-9 and AIM-120 developments ongoing at the time and later. The advantage of using a constant Missile Pk value is that it prevents missile lethality from dominating the calculations and masking nuances in outcomes due to other variations in the aircraft/missile (as a system) combinations. ‘Pk’ for the gun was more complex, and was based upon a function of the maximum burst length for one firing and the time duration of the gun hits within that burst.

The baseline “good-guys” (Blue aircraft) were assumed to have the ‘agility’ of the X-31, and the baseline “bad-guys” (Red aircraft) represented an “F-18 type aircraft”. Given the study timeframe we can probably assume the “F-18 type” aircraft comparisons were based upon the F-18C/D versions.

The study group ran multiple excursions of the 'sort-of-a-metamodel' they created, exploring the relative impacts of increasing aircraft and weapons capabilities on the outcomes of air combat engagements. A recreation of the contents in the matrix of different test cases explored and as summarized in the study’s Table 8 is shown in Figure 4.

Figure 4. Cases studied in "Practical Limits of Supermaneuverability and Full Envelope Agility"

The engagements were run under set conditions to control the number of variables. The following are the rules of engagement used for 1 v. 1 engagements:
• 120 second duration  
• No kill removals  
• Each aircraft started with same fuel load  
• Each aircraft had 4 missiles and a gun  
• Conditions for gun firing:  
- Minimum range = 500 ft  
- Maximum range = 3500 ft  
- Tracking delay = 0.2 seconds  
- Pipper size = 3.5 MIL (±2°)

All of these criteria were controls based upon expert analysis and historical records except the “No Kill Removals”. The ability to count wins and losses in a test run without ‘kills’ that would remove the killed aircraft from the equation allowed for many more engagements (trials) to add up within each computer simulation run. This approach in modeling was akin to the process of re-spawning adversary aircraft in Red Flag or similar exercises, though with a somewhat different purpose. Today, we would run more trials with actual removals because computer time is cheaper and the runs are faster.

What was learned

Figure 5. The Bottom Line of  Modern WVR Combat
In trying all the various combinations of possible enhancements (and degradations) the authors produced many relevant ‘findings’ associated with each of the design changes and combinations thereof.
1. Aircraft Agility Changes: Blue’s losses were serious, but Red Losses were even worse. Blue losses were seen as high (around 45%) for the baseline case; aircraft agility increased the red losses by 20%, while blue losses increased slightly.  
2. Enhanced Missile Capability: Blue’s losses were still serious, but Red Losses were even more severe. Blue losses were high (around 45%). However, red losses increased drastically to near 70% against the most capable missile option.  
3. Enhanced Avionics: Just improving avionics didn’t help Blue’s effectiveness or survivability. Overall, there was virtually no effect on exchange ratio or losses (which, once again, were around 45%) for the Blue Force.  
4. Combined Short-Range Missile (SRM) and Avionics Enhancements. Blue losses are again high (40-45%). Red losses were slightly lower than that for the same missile using baseline avionics, but still significant approaching 70%.  
5. Aircraft Agility with SRM Enhancements. Losses remained high (up to 52% for blue and up to 66% for red).  
6. Aircraft Agility with Avionics Enhancements. Red losses were again higher than blue losses (20% higher), but both remained high (above 45%).  
7. Combined Enhancements. Again, blue losses were high (48% for the "best" system). Red losses increased to beyond 70%.
The biggest benefit of EFM that could be drawn from the study was that EFM pays off significantly IF the A2A fight STARTS very ‘close in’ under 1 v. 1 situations AND inside the minimum range (Rmin) of the ‘then-era’ of Short Range Missiles with limited OBC (Off-Boresight Capability up to 30°), AND IF no further aircraft enter the combat (remains a 1 vs 1 engagement). Within the study, EFM largely enhanced gun firing opportunities that come well after the initial ‘long-game’ has been played and those outcomes settled. That advantage is now questionable with SRMs that have very high OBS capability. No one has to actually point anywhere near the opponent in WVR combat anymore to be able to take offensive action against that opponent.

And for the readers who just skimmed the WVR engagement outcomes above and didn't see Figure 5, let us now explicitly state that the WVR ‘short game’ IF it comes at all, during the course of this study was determined to be an unsustainable “loser’s game” between comparable opponents. This has now been known for decades, and findings such as these had to have influenced the definition of the F-35’s requirements.

Given that 1) ‘modern’ low observability predates this study significantly-- at least in the U.S.—and 2) low observability makes a foe far more lethal to 4th generation and earlier aircraft as well as more dangerous surface to air systems, it should speak volumes to any reasonable person as to why the design thrust of the F-22 and F-35 (and now others) emphasizes the reduction of susceptibility to being targeted in the first place, while (as in the case of the F-35) also emphasizes the ability to sense, discern, and assist the pilot in dealing with external threats as effectively and efficiently as possible.

We can be certain that the responsible agencies involved conducted manifold similar studies involving the effects and limits of low observability in combination with all other design drivers to produce the latest fighter designs. I can’t imagine what kind of thinking is required by the uninvolved to imagine the professionals make these kinds of analyses and force structure decisions without due diligence.

How many more pilots, planes, and support assets would ‘blue’ forces need to win a war of attrition if only WVR-capable “day fighters” and/or non-‘stealth’ aircraft are involved? This is an important question. After all, simple ‘less capable’ fighters are what all those earnest and/or Faux Reform critics advocate to varying degree when they are insisting the actual experts are doing fighter acquisition “wrong”. Advocates of less capable systems are advocates for a strategy of Wars of Attrition.

The frequency--how often WVR conditions would occur between aircraft (again, they were all non-LO aircraft) -- was to be a subject of the Arena runs of the future. I’ve not found the results of this effort in unclassified sources, but given what we’ve learned from all air combat that has occurred since that time, and experiences in major exercises such as in recent Red Flags, I would suspect WVR encounters, and certainly 'extended turning' fights, will become even more of a rarity.

Given the improved min-range performance of short-range missiles and future non-kinetic weapon solutions on the horizon, extended maneuvering fights might become extinct. At the very least, they could become ‘black-swan’ encounters not worthy of driving aircraft design in the future nearly as much as in the past, that is, at least for the foreseeable future.

How potential enemies see the future is indicated in how hard they work to either follow the US lead in design trends or in attempting to devise ways to mitigate the advantages sought by the U.S. and its allies. “Advantages” such as those that come from the capabilities of the Fifth Generation fighters.

The entirety of EFM-AASPEM work performed during the study was devoted to within-visual-range 1 v. 1 combat. Comparisons were made based on firing opportunities, exchange ratio, and losses. One really needs to read the study to understand the nuances of the findings, but by way of introduction to the findings, let us observe what key conclusions were drawn. [ My comments in brackets]:

The most significant contribution to operational effectiveness was increased OBC coupled with enhanced avionics (mainly due to helmet mounted displays). Further improvements were possible when Rmin [Minimum Range] was reduced. [Missile Rmins have been getting smaller, and off boresight capabilities have expanded wildly beyond any assumptions in the study since the report was published. The utility of an advanced HMD has been recognized as far back as the earliest F-15 requirements list. It’s good to see technology has finally advanced enough for the concept to have come of age in the F-35.]  
Missile and avionics enhancements have to be harmonized to fully make use of the improvement potential. It should be noted that missile/avionics OBC enhancements will provide even higher impacts in the many-on-many environment. [And the F-35’s integrated avionics/sensor fusion are now the epitome of this idea made real.] 
Aircraft agility contributes to a certain extent, although not as significantly as missile/avionics enhancements. To make full use of agility, new aircraft designs might be required concerning aircraft kinematics and aerodynamics. [‘Agility’ as defined by the research pointed to just the kind of design philosophy used for the F-35.]  
Conventional aircraft performance enhancements do not improve system effectiveness. If envisaged, they would also require new aircraft designs. [Asymptotic limits of maneuverability have been reached. Perhaps it is a plateau for the current technology available, but I would suspect there will have to be a breakthrough no one has yet identified as needing to happen first.]  
Degraded aircraft performance [Aero efficiency and Thrust to Weight for the most part] can hardly be compensated by enhanced agility. The degradation decreases the conventional turn capability which is a "defensive" potential. A decrease of this potential enables the opponent to generate increased firing opportunities. [In a WVR world fighters will still need to be able to turn and burn. Think of it as the lower limit of maneuverability isn’t going away just because the practical upper limit has been reached.]  
Degraded aircraft performance might be compensated by suitable missile/avionics enhancements. Although the same degradation concerning "defensive" potential applies, more firing opportunities can be generated earlier. [This is actually not a new thought. If Glenn Bugos’ history of the F-4 is to be believed (and I believe most of it is quite on target), much of the F-4 Phantom design was philosophical: driven by how best to divide the ‘capability’ between the missiles carried and the aircraft carrying missiles and to a lesser extent fleet radar support.]

Some of the last findings in the study report can be said to have become even MORE true since it was written [Brackets still mine]:
During the last 10-12 years, [and now two decades since the study report] there has been significant improvement in missile technology. Next generation missiles [ASRAAM, AIM-9X, etc.] have better seekers and more sophisticated fly-out capabilities to make successful use of better thrust vector control, thereby improving missile agility in the close-in environment as well as endgame performance. [The missile performance realized in today’s generation of missiles exceed that ever envisioned in the study]. In addition, [aircraft] avionics have improved to make use of high OBC. [And of what the study authors would have considered impossibly-high OBC.] These developments [through and past 1995 and that were and are ongoing] make the new generation SRM/avionics attractive; however, the high mutual loss rates [expected to increase further] with all type of enhancements will "stress" the recommendation to urgently improve situational awareness as well as beyond-visual-range effectiveness to avoid WVR/CIC. [And unsurprisingly has been incorporated into the F-35 design.]


“Fighter Aircraft” Design as Always is STILL Driven by Operational Requirements

(Bumped)

Operational requirements have evolved continuously since the first fighters flew. It would be as large a folly to insist that a fleet of 4th generation fighters could meet the needs of current and foreseeable operational requirements as to insist a WWI aircraft could meet the requirements of a WWII operational environment.

Compare what we know now about ‘where’ air-to-air combat is going with the kinds of capabilities built into fighters like the F-35 and F-22, and what potential ‘near-peers’ are trying to build. Given the study findings, 5th generation fighter capabilities, and actual air combat history, WVR combat is now something to be even avoided more; something any A2A combatant would seek to avoid if at all possible and only to be endured if unavoidable.

Defense planning and foresight informed by experience and research, such as that embodied in the study we just reviewed, produces the requirements for future weapon systems that resulted in the F-35. I marvel at how much hybris the uninformed must possess to shamelessly assert alternate realities while second guessing legions of actual subject matter experts who have done the work day-in and day-out for decades to deliver viable solutions to defense requirements, and who have access to the kind of data and history needed to actually carry out such responsibilities.

The future of fighter design and design requirements will change as the operational environment changes. This is why as soon as one ‘generation’ of fighters is being fielded, work begins to define what will be needed in the next generation. Work on what became the F-15 began as soon as the AF got the F-4. The F-22 is descended from the first efforts to define what would be needed after the F-15 as the first F-15s were in development. Yes, we can envision some of these future changes (lasers anyone?) and can imagine how strategists and designers will cope with them. But the entire battlespace will continue to be reshaped beyond any analyst’s imagination and prevent them from peering too far into the future just as it always has been.

NOTE:
Nowhere in this series of posts, or in any other posts the reader will find here, is the assertion made that ‘maneuverability’ (however one defines it) is "unimportant"-- in the past, modern day or immediate future. This must be stated unambiguously up front because I've seen the tiresome broad-brush accusation of same made too often when anyone dares challenge some closely held belief as to maneuverability’s relative importance to fighter design, or dares challenge the vague reasons why many of the uninitiated think “maneuverability” is important.


A Request in Closing: If history repeats itself, when this post is referenced on a ‘board’ or comment thread somewhere, some yahoo is probably going to contest what I have written as “SMSgt Mac is wrong…”. As if their disagreement is with ‘me’-- when they’re really expressing their disagreement with…y’know…the ACTUAL experts I cited. I usually trip over these weak statements. while looking for something else, ages (sometimes years) after the mischaracterization of what I typed is displayed: long after the disinformation damage is done and everyone has since moved on to other topics. Soooo…If one finds this happening somewhere after this post, it would be much appreciated if a reader or two would reply in response that “SMSgt Mac said you would try that B.S. deflection”. Feel free to use the direct quote.

We Can't let an F-35 Myth Die!

The "Phone it in Edition"

The only thing worse than 'phoning it in'.... is doing so with incredibly poor timing.

28 April 2017
“For me, it’s my first time dogfighting against an F-15”….“Dogfighting is a test of pilot skill, but it’s also constrained by the aircraft’s capabilities and I’ve been really impressed by the flight control and maneuverability of the F-35.”


 4 May 2017 click-bait regurgitation of an article first written in 2015 
“Close in, the JSF does not have the maneuverability of the Raptor––or even a F-16 or F/A-18.”


When Majumdar first started at FlightGlobal he showed promise. Alas, unrealized to date.

President Trump & The F-35: He's Done the Impossible!

F-35 Costs coming down as expected. Deal with it.
 
President Trump set wheels in motion that have turned the long-standing 'F-35 is unaffordable' deception inside out. The whole world now knows the F-35 unit costs are coming down exactly as planned and for -- as any honest person who's been paying attention already knows -- the same reasons the program has been citing all along.

How did Pres. Trump spread the word/change the narrative so quickly?
He leveraged the mainstream media's 'narrative priorities' and the lockstep and unthinking pursuit of narrative to suit their priorities.

Kneejerk Media PWNED

Thanks to the media's rabid dislike/disapproval of President Trump and ANY of his actions,

1. We now have outlets like the Washington Post shifting their 'all negative' cost narrative found in past F-35 reporting to finding themselves having to not only acknowledge, but ASSERT the costs were coming down anyway, and AS PLANNED in an attempt to deny President Trump any credit for same.

2. And when the media latched, again in lockstep, onto the "costs were already coming down" story, LM's CEO casually mentions 'but' the President DID help, if only by sharpening the negotiations' focus on 'Costs'.

Heck, since this started we even got James Fallow's/Atlantic Media's quasi-serious DefenseOne quoting ex-CAPE officials the week after they retired saying:
Over the past five to six years, the F-35 program “has performed pretty close to the [budget] estimates,”

My take

President Trump's involvement/interest has helped topple an information blackout and for now a Faux Military Reform Industry meme. I'm reminded of the old quote:

A man may do an immense deal of good, if he does not care who gets the credit for it. 
I don't care what people think about 'why' the unit costs are coming down as planned. I'm happy just knowing that people know they ARE coming down. Driving the media crazy over it is just a Trump side-benefit.

B-2's Bomb ISIS!

H/T Edpop at F-16.net This is pretty much a repeat of what I posted at F-16.net

It is interesting that CNN focuses on the body count.

It does gives proof to the old adage "If it bleeds it leads' but my, how 'Southeast Asia 1965' of them.

What's more important: Were the right terrorists killed. This is pretty much a repeat of what I posted at F-16.net

Q: Why use B-2s?
A: So ISIS never saw us coming.

Q: Why 2 B-2s to drop 38 weapons when 1 can carry 80 500lb JDAMs?
A: To bomb both locations at the same time, like probably down to the last second unless they wanted to cause a response in one first by bombing the other. And more than 38-40 would have probably been overkill.

Q: Was this cost-effective?
A: Aside from killing the terrorists who would have carried out attacks in Europe and probably elsewhere now and later (CNN and their 'militants'....F*! both.) it probably:
a.  flattened their training facilities, weapons building capability and stockpile and the trainers of future terrorists,  
b. it will also make the survivors look up in the sky at night and loose their beauty sleep.
The immediate and later costs of letting any attacks happen probably far outweighed the cost of flying 2 B-2s and expending a few bombs.

There are some less obvious positives about this, given the 'international' interest in the region, but I will not air them here.

Now  expect some slacker in the media to use the 'kitchen sink' definition of $/FH to rail against the strike as 'wasteful' in 5...4...3...2...

On a personal note...

I had a very small role in fielding the Smart Bomb Rack Assembly (Smart BRA: gotta' love it). I suppose since they dropped only 38 JDAMs they could have used the Rotary Launchers (RLAs) but that's OK too, since I also played a small role developing and testing the smart weapons interface that allowed GATS/GAM then JDAMs etc. to be dropped as well.

I feel pretty good about all that right now.

Updated 20 Jan 17: Well now the reports coming in say 'over 100' JDAMs, and some specifically assert 110 JDAMs were dropped in two camps. It appears by some accounts there were to be up to four camps targeted initially but the terrorists had consolidated as well as relocated between the time the missions were conceived and executed. I'm sure the AF still enjoys it when targets bunch up. 
It would have been hard to move assets around the Middle East to hit Libya like this without contrarian interests leaking it beforehand, I still remember Operation Allied Force and how ops departures out of Comiso seemed to be on TV in real time. The message here is: you won't see us coming unless we want you to.   

As it perhaps looked like a last tasking from Former President Obama to our enemies, I imagine they were just as surprised as some of the media appear to be when a Buff and UAVs took out a few AlQaeda in Syria in followup

F-16 and F-35 parallels: Boy Reporter Gets Few Facts Right, Story Wrong

Hat Tip: 'tbarlow' @ F-16.net

This is just too funny and too easy to debunk for me to pass up. I just gotta point out the stupid involved. Kyle Mizokami tripped over a thread in Reddit and built a nice 'on the one hand, but on the other hand' F-35 "narrative" for Popular Mechanics that is so lame it answers the question as to why most media writers aren't paid as much as they think they're worth. It is a shame too, because with really very little research, and demonstration of a minimal understanding of economics--specifically the 'time value' of money and proper use of deflators -- he could have contributed significantly to killing the false narrative that the F-35 program is 'plagued by (fill in the blank)'. Instead, he tries, and fails to make the F-35 look bad, using numbers that when applied correctly only make the point that the F-35 program, and the problems that have been encountered are in no way unique.

Here's the PM story:
A New York Times newspaper article describes a beleaguered American fighter program enduring delays, escalating costs, and technical problems. Another article about the F-35 Joint Strike Fighter no doubt, right? Nope. It's an article from 1977 about the F-16 Fighting Falcon.  
The F-16 was the original multinational fighter. Developed by the United States with Belgium, Denmark, the Netherlands, and Norway as partners, the fighter was designed to be an agile, lightweight, daytime fighter to replace aging fighters such as the F-5 Freedom Fighter and the F-104 Starfighter. At $6,091,000 per unit—$27.1 million when adjusted for inflation—it was also supposed to be inexpensive.  
Many of the F-16's past problems are mirror images of the issues we see in the F-35. According to the article, the Air Force expected the F-16's research and development costs rose by some $7 billion to reach $13.8 billion by 1986. Adjusted for inflation, that's $54.7 billion in today's dollars. F-35 R&D costs, on the other hand, are estimated at $107 billion dollars to date.  
Like the F-35, the F-16's problems arose from technological issues and design challenges. The fly-by-wire mechanism of the F-16, in which an aerodynamically unstable but highly maneuverable aircraft was tamed by computers to keep it flying, was an expensive problem that was eventually solved. Like the F-35, the F-16 had problems with its engine and also had to be modified to placate U.S. allies who wanted a fighter capable of air-to-ground missions, a real multi-role fighter.  
Still, as similar as the problems between these two planes are, the F-35's problems are much more intense. The F-35 was originally slated to cost $50 million apiece—nearly twice the original cost of the F-16 at today's prices—but the three versions of the plane currently run anywhere from $112 to $120 million each. The F-16 encountered months of delays, but the F-35 A/B/C models will, on average, be delayed half a decade. 
Yes, America and her allies have been down this road before, but this time it is a lot rockier.
First, the 'costs' narrative whereby Mizokami attempts to make it look like the F-35 is MUCH worse than it's predecessor....when it is not that different at all.

RE: The F-16's “$6,091,000 per unit—$27.1 million when adjusted for inflation”.

I don’t know where he got the $27.1M inflation unit cost value (though given the depth of research he shows I suspect he just found a number) but it strongly correlates with Contemporary Opportunity Costs between 1976-77 and 2015. In terms of a project’s Economy Cost (relative share of the GDP used: the correct figure for 'projects') that 1977 F-16 unit cost would equal $58.2 million in 2015 dollars. [Note: Calculators I used for the interested are here.]

RE: “the Air Force expected the F-16's research and development costs rose by some $7 billion to reach $13.8 billion by 1986. Adjusted for inflation, that's $54.7 billion in today's dollars. F-35 R&D costs, on the other hand, are estimated at $107 billion dollars to date”

This is an odd disconnect from Mizokami's unit cost claim and the R&D figure he used for the F-16 DOES equal about $54B in 2015 Economy Cost, so who knows why the author came up with a lower number for the unit cost of the 1977 F-16 in “today’s dollars”. It was widely touted early in the F-35 program that we could develop three aircraft for the cost of 1.5 to 2 aircraft. Craptastic! RAND policy pieces non-withstanding, let's note that the estimated F-35 R&D costs that Mizokami uses (and we will watch these estimates as they become 'real') are running about 2 times that of the 1977-era's F-16 R&D costs when adjusted for inflation. That seems pretty reasonable, considering the F-16 is the cheapest of the 'Big three' aircraft designs (F-16, F-18C/D, AV-8B) whose capabilities drove the requirements for the F-35 design.


Even the F-16 as we know it today involves much more content and cost as Mizokami indirectly acknowledges than that of the 1977 F-16, so how about we consider all the additional ‘content’ the F-16 now has that it didn’t have in 1976-77? What was the later ‘development cost added’ that came with the later ‘value added’? We can't compare apples and apples directly, but we can get an idea about unit costs at least . In 2012, it was said that the F-16V would be less than half the “then” cost (Richard Aboulafia) of the F-35. Anyone remember the 2012 F-35 unit cost? It was $125-150M a copy depending upon who’s chart you’re looking at in whatever FY$’s being discussed. (see charts lifted from F-16.net's voluminous archives to the left) That would make the F-16V somewhere in the $60M-70M range in 2012 dollars. Guess what that is in 2015 dollars? Go ahead do the calculations). That's right. the F-16V would probably cost $70M-$80M (Economy Cost) in 2015 dollars. Note that also does not include the same 'content' that comes on an F-35.

 

 

 

People who rail about F-35 costs fall into one or more of three camps:

1. The willfully ignorant or gullible who’ll fall for anything.
2. The liars who have their own agendas
3. The internet's village idiots.

Enough about dollars. How about some history instead of Mizokami's stories?


RE: "Like the F-35, the F-16 had problems with its engine and also had to be modified to placate U.S. allies who wanted a fighter capable of air-to-ground missions, a real multi-role fighter."

1. The AF ALWAYS wanted the bells and whistles that were finally delivered with the first Block 30 F-16s. It wasn't the 'allies'. Don't believe me? Just look at what then recently retired Gen John Vogt who had commanded USAFE was saying about what was needed while the F-16 was in early development via a Euro 'Hit piece' from the period:
This rather poor documentary looks even sillier now than it did at the time, given the successes of the F-16 (airplane and program) that came soon thereafter. But it's value in illustrating how the stripped down version of the F-16, the day-time knife-fighter that the faux reformers wanted, was a politically driven, and not operational requirements-driven configuration endures. Of course, we could also simply review the history of the development to see the USAF always wanted more on board the F-16. This was made possible only by advancements in small electronics technology that then had to be developed for military aerospace. And TANSTAAFL.

RE: "The F-16 encountered months of delays, but the F-35 A/B/C models will, on average, be delayed half a decade."

'Delays' are a measure of the difference between 'time planned' and 'time scheduled' to reach some meaningful achievement. If you want to compare the F-16 development with the F-35's, then the baseline F-35 Block 3 will be achieved two years faster (with about 1600 fewer aircraft produced) than the F-16's Baseline Block 30. The biggest difference between the F-16 and F-35 programs is the differences in size of the initial 'brass ring' being sought.   

Finally, a minor nit to pick about the F-16 so-called 'engine problems'. If Misokami cared to do some research, he'd find that the problems never really affected the F-16 like the F-15, partially because of the installation, and partially because the F-15 was the lead user o the PW F100.

Misokami's story could have been a good one. In any case, if Mizokami read a little more widely, he would have known about this part of F-16 development 'history' over NINE Years ago.

Yes, that's right. All has proceeded as I have foreseen.

Northrop Grumman's B-21 Bomber Concept Revealed

Newly released B-21 unclassified computer art? Deja Vu Baby!

The artist's concept revealed by the Air Force for the newly-revealed B-21 "bomber" (will that moniker survive or will it become something else when it is all said and done?) is "Deja Vu all over again". Cool.

Contrast the B-21 computer sketch just released:

...with the first artistic rendering of the B-2 for public release:
  

Someone has a sense of humor...and history.

Note the similarities between the two in what is obscured and what is revealed. Both illustrations mask the exhaust design completely and 'shadow' the aft window areas. The B-2's debut drawing had more details shown for the intakes, but there may not be any details to be masked in the B-21's design....or some interesting details left out perhaps?

Both illustrations give ZERO indication of what the underside shape or volume may be. The B-2's leading edge rendering gives a hint to what had become one of its most critical design features: the 'toothpick' leading edge (P.64). I do see something that I find kind of surprising in the B-21 illustration (not going to say what it is until maybe after I talk to some folks) but I wonder now if there's a critical design feature hinted at here that will only come out in time just like the B-2's 'toothpick'?

I'll let our potential enemies' minds boggle over the possibilities. I'll also just enjoy the possibility that the data from original B-2 high-altitude design optimization seems to have come in handy for Northrop Grumman in preparing their winning design.

Minor Snickers

1. So much for all that cranked-kite speculation eh?
2. The conspiracy nuts are going to have a field day with the revelation there has been no prototypes built.

GAO's LRS-B Findings Tomorrow?

Tomorrow was the planned release of the GAO's findings on Boeing's LRS-B contract protest. It technically is two days later than the required timeframe/due date, but the deadline was on Sunday and today was a Federal holiday. Will the tempest-in-a-teapot over someone's second-hand ties to a Northrop (or Northrop Grumman) pension that emerged last week delay the announcement? I think it would be pretty silly for it to cause delays, since the person involved had nothing to do with the source selection: he was THAT guy's replacement AFTER the selection was made.

But we live in the 'stupid era' and lawyers are involved. 

What wouldn't have raised an eyebrow a couple of decades ago will set off a storm of controversy because...well because the coddled, noisy elements of society are particularly ignorant and easily manipulated these days and soapboxes have never been so cheap.

Standing by......

FYI: GAO's findings, whatever they are, are not binding on the DoD. But if the DoD wants to go against them, it will require varying degrees of political capital to be spent. Should be interesting... if it is not boring...when the news is finally let out.

LRS-B Cost Story Not Really About LRS-B

DefenseNews has a young posse of correspondents that are pretty hapless when it comes to analysis, but they still manage to do some actual reporting from time to time. If you can stand having to read around the speculation, hearsay, and opinions coming from the usual anti-defense sources who seem to feed DefenseNews and most other D.C. media outlets, you can pick up some odd useful stuff.

... In last year’s budget request, the Air Force included about $12.6 billion in its research, development, technology and evaluation account for the next-generation bomber from FY17 through FY20, according to official budget documents. But for the same time period, the service’s FY17 funding profile for LRS-B is about $9.1 billion – a significant drop of about $3.5 billion.  
Budget observers took to Twitter Tuesday after the initial budget rollout to lambaste the Air Force for cutting resources for the bomber. However, the reduction simply reflects the service’s updated cost estimate for the program since awarding a contract to Northrop Grumman Oct. 27, Air Force deputy for budget Carolyn Gleason told reporters Tuesday at the Pentagon. ...


Now the real news here isn't that the estimated program cost dropped nearly 28% with better newer data, or that some people over-reacted to the budget change and ASSUMED the worst.

The REAL story is:
  1. How much cost estimates can and do vary wildly depending upon assumptions made and external factors...even over short periods of time.
  2. No cost estimate involving the design and fielding of new technology in an unstable funding environment is any more 'REAL' than ANY other.
These two points should be kept in mind whenever one hears a cost estimate asserted in the press and is received as gospel. Many fonts of these estimates, such as Todd Harrison, who is now a go-to CSIS soundbite source, need to start assuming some mantle of humility in their cost and budget assertions, if only to at least PRETEND that someday they will be held accountable for their applying inconsequential knowledge to consequential things.

I submit that ALL such cost estimates should be prefaced from this day forward with...

Dave Majumdar's F-35 'Punk Journalism'...Again

Whereby 'boy journalist' double downs on David Axe's 'Dogfight' B.S, ignores reality and dances around Libel in just a few paragraphs. 

But hey! Its always fun to watch someone debase themselves for pennies a word right?...right? 
Today, Dave Majumdar, once a promising aero reporter, apparently needed some rent money. Why else would he fabricate another F-35 click-bait hit piece for the lower-brow crowd, (update: the Punk is now the 'Defense Editior' of the digital rag) rehashing the pap that David Axe used to set off a disinformation cascade? Now I could spend all night Fisking Majumdar's craptastic article to include "27 8x10 color glossy pictures with circles and arrows and a paragraph on the back of each one explaining what each one was to be used as evidence" but there's only a couple of things worth my time, nailing Dave to the wall, that should cast the rest of his 'pap' under the proper spotlight. The first is his apparent (willful?) inability to discern information from 'spin':    
Meanwhile, proponents of the F-35—primarily Lockheed Martin and the JSF program office (JPO)—tried to dismiss the results—aggressively calling out the War is Boring outlet by name. The company and the Pentagon claimed that the tests were not truly representative because the F-35 test article involved in the trial versus the F-16 was not equipped with a full set of avionics, didn’t have its stealth coatings, and did not use the jet’s helmet-mounted display and, moreover, was not equipped to simulate high off-boresight missiles like the AIM-9X Sidewinder. Besides, the F-35 was designed to fight from long-range—the JPO and Lockheed claimed.Both sides of the debate are correct—but neither side is telling the whole story. As a good friend on the Hill recently told me: “In political communications, facts are an interesting aside, but are completely irrelevant. What we do here is spin.” That’s exactly what’s happening here—both sides are selectively cherry picking facts to make their case—spin.

Dave...Tell your 'friend' to F.O.A.D.

"Tried to dismiss the results" Dave? Facts are not "an interesting aside" to people who design and build weapon systems.  What the JPO and LM responded with was 'The Truth'. It was a post-stall agility test, testing for areas where it might be worthwhile to 'open up' the control laws (CLAWs) and was not a 'dogfight'. 

The Testing in Question was Described Ahead of Time Last Year 

Not only was what the JPO/LM response the TRUTH, it was one that was KNOWN and in the public domain the year BEFORE the test ever occurred and therefore it is also a delightfully 'provable' truth. I buried the lede with this point in an earlier post, but I recreate an excerpt here:  
From the 2014 AIAA paper "F-35A High Angle-of-Attack Testing"[1], authored by a Mr. Steve Baer, (Lockheed Martin "Aeronautical Engineer, Flying Qualities" at Edwards AFB), and presented to the Atmospheric Flight Mechanics Conference held between 16 and 20 June 2014, in Atlanta, Georgia we find that F-35 High AoA testing was designed to follow in the following progression:  
"The test objectives for high angle-of-attack testing are as follows:
1) Characterize the flyqualities [sic] at AoAs from 20° to the control law limit regime with operationally representative maneuvers.  
2) Demonstrate the aircraft’s ability to recover from out of control flight and assess deep stall susceptibility 
3) Evaluate the effectiveness and usefulness of the automatic pitch rocker (APR)  
4) Evaluate departure resistance at both positive and negative AoA with center of gravity (CG) positions up to the aft limit and with maximum lateral asymmetry.  
5) Assess the handling qualities of the aircraft in the High AoA flight."
Now, in case a 'punk journalist' or other factually-challenged reader wanders by (am I psychic or what?), we need to be clear that #5 has nothing to do with "dogfighting". We know this because Mr. Baer makes two points shortly thereafter within the paper. 
The first point is relevant to the state of the testing at the time of his writing. I observe that this paper was written during Objective #4 testing and published at about the time it concluded. This observation is supported by the paper's passage [emphasis/brackets mine]:

With intentional departure testing [Objective #4] wrapped up, the team will soon move into departure resistance [Still Objective #4] and plan to remove the SRC now that these systems have been verified. In this phase of testing, the jet will test the CLAW limiters with much higher energy and rates than previous testing, fleshing out and correcting areas that may be departure prone. Lastly, select operational maneuvers [Objective #5], such as a slow down turn and a Split-S, will be used to gather handling qualities data on high AoA maneuvers. With the completion of this phase, the F-35 will be released for initial operational capability in the high AoA region.

Note: 'SRC' is a 'Spin Recovery Chute'.
Clearly the testing was not yet at step #5 at the time of writing but to emphasize same, the author followed the above paragraph with [brackets/emphasis mine]: 
While the flight test team will explore legacy high AoA maneuvers for handling qualities, it will be the Operational Test and Evaluation team that will truly develop high AoA maneuvers for the F-35. In the operational world, a pilot should rarely be taking the F-35 into the high angle-of-attack regime, but the ability to do so could make the difference between being the victor or the victim in air-to-air combat....
So with this paragraph, not only does the author expound on the exploring of "legacy high AoA maneuvers" that is to come, he specifically identifies Objective 5 test "Handling Qualities" objectives and assigns the kind of testing that will "truly develop high AoA maneuvers for the F-35" (vs. 'legacy' which may be differed 'from') to the Operational Testers and NOT part of the Edwards AFB Developmental Test Team activities.
In a nutshell, just within these two paragraphs that Baer wrote in early/mid 2014 is precisely what the JPO/LM stated in their official response to Axe's so-called 'article'. 
Therefore the "reasonable man" may logically and confidently conclude the LM/JPO response:
  • WAS NOT simply something that was contrived in response to Axe's made up bullsh*t but...
  • WAS accurately asserting what the testing was truly about..
Go ahead Dave, spring the few bucks to buy a copy from the AIAA. Have someone with the requisite knowledge explain it to you.
Majumdar's incompetence takes him into another reprehensible act, whereby he uses David Axe's idiotic output as the justification for insinuating Billie Flynn lied to him:
The company has repeatedly made assertions about the F-35’s performance that have later proven to be false. One example I can cite immediately is when Lockheed test pilot Billie Flynn told me how a fully laden F-35 has better high AOA performance and acceleration than all comers save for the F-22. The test report that David Axe managed to obtain clearly shows Flynn’s assertions to be false. 
Nice one. Does 'Majumdar' mean 'A**hat' in English? Aside from the fact Majumdar implies Flynn is a liar, there's also the comparatively minor commission of a non-sequitur to boot.  

The rest of Majumdar's 'article' is crap too, just not worth bothering with in light of the above affronts to reality. A 'great' day for aero journalism, eh?

“Fighter Aircraft” Design: Driven by Operational Requirements


Part 1: Introduction

In the wake of the disinformation cascade set off by the mischaracterization of an F-35 Developmental Test report leaked to the poster-boy for Punk Journalism (and his equally hapless compadres) it became apparent that somebody, someplace should highlight just how infantile all the F-35 H8er and click-bait copycats have been on the subject.

Since ‘Axe is Boring’ ‘broke’ the story (if you can call being hand-fed the raw data by some other cretin and then making sh*t up about things he doesn’t understand ‘breaking’), I think we’ve seen every perversion of reality about the test itself, the relevance of the test, the F-35’s capabilities, the history of air combat, ‘dogfighting’, and airpower-in-general trotted out and gleefully regurgitated as if it were gospel by the innumerate and the illiterate.
As creative as the fiction published about the aircraft (it was an early production 'A' model: AF-2) performance during  the Developmental Test has been, it seems most if not all of the F-35 criticisms related to the ‘leaked’ test report fall into two broad categories. In the first category we can place all the claims/accusations that the F-35 is not somehow ‘fighter’ enough to successfully engage in air combat. In the second category we can place all the assertions that the scenarios flown in this one test were representative of how the F-35 would perform Air Combat Maneuvering aka ‘Dogfighting’ in actual combat.

We will deal with both these strains of criticisms in what will be Part 2 and Part 3 respectively within this short series. In Part 2, we will recall a rather cogent, insightful and in many ways prophetic AIAA paper from 1970s: “The Characteristics of a Fighter Aircraft”. This paper is the text transcript for the Wright Brothers Lectureship in Aeronautics speech given by Prof. Gero Madelung (speak German?) to attendees of the annual AIAA Aircraft Systems and Technology Meeting in 1977.  I’ll then introduce the thoughts on fighter development from a very influential and widely-cited engineer (among aircraft design types anyway) who among other things can be considered the originator of the concept ‘supermaneuverability’.  Thus, Part 2 (which may have to be broken into sub-parts if it gets too unwieldy) will bring us up to speed on top-level ‘fighter’ aircraft design drivers right up to the present-day state-of-the-art, and maybe a peek or two at the future.

Whereas Part 2 will provide proper background and perspective, Part 3 will be where the perspective will be applied and so will be more ‘analytical’. We will break down a 1 vs. 1 air combat scenario into a high-level conceptual model of constituent phases and associated combatant states. Then we will apprise the F-35’s potential advantages and disadvantages at different points of reference during engagement scenarios as it moves into and out of those phases and states and under what conditions it can navigate its way through those phases and states. We will also weigh the relevance of those advantages/disadvantages to possible combat outcomes.

Part 3 will take some time to complete after Part 2, so I will ask the readers to bear with me on any delays, or perhaps I will invite comment on aspects of the approach to Part 3 as I build the conceptual model. We should not have to account for probability of outcomes and only illuminate the ‘possibilities’ for discussion-- which will simplify the problem significantly but not to the point that careful construction will not still be necessary just to avoid oversimplification on the one hand or sophistry on the other. This is the hard part of Part 3: to make complete enough to be valid and convey meaning, not so complete that too many eyes glaze over. The topic would be a lot easier for me to treat if there were more authorized references to the F-35’s Developmental Test that I could tie into, but we’ll muddle through without them somehow.

This is also probably going to seem awfully obvious and trivial in many places to some, but I want to have a single reference to point non-technical minds to in the future. -- Because this is one of those topics where you could get worn out just beating down the same stupidity and misperceptions every time they pop up.
Finally, in each part I will include a reminder:
NOTE:
Nowhere in this series of posts, or in any other posts the reader will find here, is the assertion made that ‘maneuverability’ (however one defines it) is "unimportant"-- in the past, modern day or immediate future . This must be stated unambiguously up front because I've seen the tiresome broad-brush accusation of same made too-often when anyone dares challenge some closely held belief as to maneuverability’s relative importance to fighter design or dares challenge the vague reasons why many of the uninitiated think “maneuverability” is important. 
This note won’t stop tired criticisms from arising, but it will make intelligent people stop and think before they paper any comment thread with false conclusions. And this series of posts isn’t for the people too stupid to know better anyway.

Part 2 is here

CNO Nominee Richardson Got These F-35 Questions Too?

I told them I didn't want the job, but I answered them anyway.

Hat Tip "spazinbad" @ F-16.net

SMSgt Mac appearing before SASC?
CNO Nominee Admiral Richardson answered some pre-confirmation hearing questions. I like his answers pretty much, but like my answers better. It comes with the freedom of being long retired (as well as never being an Admiral).

RE: Tactical Fighter Programs
The F-35 Joint Strike Fighter Program, which is the largest and most expensive acquisition program in the Department’s history, was formally initiated as a program of record in 2002 with a total planned buy of 2,443 aircraft for the U.S. At projected procurement rates, the aircraft will be procured by the Department well into the 2030 decade to reach its total quantity buy. The program has not yet completed its systems development and demonstration phase, and is not due to enter full rate production until 2019, 17 years after its inception.

The Navy’s FY16 budget request indicates a program of record of 369 F-35C, with Navy procurement continuing throughout the life of the F-35 procurement program. The overall requirement for 2,443 aircraft was established nearly 20 years ago. Since that time, however, there have been countervailing pressures to: (1) reduce force structure to conserve resources; (2) improve capability to respond to prospective adversary technological advances and increased capabilities from updated threat assessments; and (3) respond to an evolving national defense strategy.



Do you believe the Navy’s F-35C requirement is still valid?
Well Senators, that’s quite a preface to a “yes or no” question. But as it comes from such an august body as the Senate Armed Services Committee, I will use the working assumption it is offered to provide proper perspective to the questions to come, rather than an attempt to ‘poison the well’,and so the Committee’s prefacing informs my response,and I believe due diligence also requires me to to expand upon the very fine points the Committee raises, in part as an answer to this first question. 

As the Committee very well knows, the F-35 Program is as large and expensive as it is because it is really three programs in one. While there have been studies that have reviewed whether or not combining programs was worth the effort, we must note that aside from them all having contentious ground rules and assumptions embedded, that NONE of them measured the costs and benefits of the F-35 program against the typical number of programs we would have to undertake to successfully field three different aircraft. Can there be any doubt looking back at history that at least four or perhaps five programs would have to be attempted to actually field three different jets? Can we possibly fathom the procurement costs per airplane if we had attempted to field the minority F-35B and F-35C as stand-alone programs? Mr. Chairman and Committee Members, the Navy and Marine Corps budgets are very blessed to have the Air Force subsidize The Department of the Navy’s rent-seeking by absorbing a disproportionate percentage of the net development costs.

As the bulk of the development is behind us in sunk cost and schedule, and there is no indication that the way forward is too difficult, completion of the systems development and demonstration phase should not be a problem.

That it will have taken 17 years to reach full rate production would be an issue above my station if I were still on active duty: I would not be in a position to second-guess prior Congressional decisions to stretch development and delay production, trading risk for schedule and cost. It would also not be my place to pass judgement on the actions of prior Congress’ that created the three-in-one program approach in the first place. 
As a retiree who returned to civilian life over twenty years ago however, I am free to answer that the former was typical, foolish, political tinkering and/or ego-stroking on the part of Congress. The latter however, is shaping up to have been a very good idea by your predecessors.

And so the final answer to your question is therefore, of course: “Yes”--the F-35C will be a VITAL part of the future Carrier Air Wing.



Do you believe the Navy can afford and needs to procure 310 more F-35Cs with a procurement cost of over $42 billion?

As to ‘need’, the F-35C provides essential 5th generation strike fighter capability to our Carrier Air Wings. Without this capability, we cannot achieve air superiority. The Department of the Navy currently has a requirement for 340 F-35Cs. That number needed of course is always subject to revision as national strategies change and new information is made available. For example, on the one hand, the Navy doesn’t yet have any operational experience with low observable or fifth generation capabilities. As the Navy gains experience, it will probably create opportunities and incentives to not procure more of or retire older systems faster on the one hand. On the other hand, the Navy has a history of buying aircraft over long timeframes due to expected attrition, and given the F-35C’s stellar initial sea trials, we may just not lose as many jets like we have in the past and so they will not need replacement. If I were confirmed as CNO, I would work with the Chairman and other service chiefs to revalidate the appropriate number of aircraft the Navy requires to meet the mission.

Speaking to the cost figure offered, let us note that the numbers you mention are either future inflated dollars or dollars that include developmental cost dollars that are already sunk, both, and/or are based upon presumptions of future economic factors that may or may not apply. They are also spread over how many years? I would enjoy exploring the nuances of these numbers with the SASC, numbers that should never be aired in a casual manner, as no doubt the SASC would agree.


Do you believe that the Navy will still want to buy the F-35C, an aircraft design that will be 30 years old before the Navy production is scheduled to finish?
Well let’s see, we’re flying the F-18C/Ds and F-18E/F/Gs right now. The current versions are evolutions of a design originally produced in 1975 and are still in procurement. That’s 40 years since inception. So 30 years should not be a stretch at all for the Navy and the F-35, especially considering that unlike its predecessors, the F-35B and C are designed to evolve as required over time. Right now the Navy is committed to making the F-35C the next Carrier Air Wing fighter, complementing the F/A-18E/F until the F-18 reaches the end of its lifetime in the 2030s when the basic design will be over 50 years old. I believe once the fleet gets its hands on the F-35C, the fighter/strike community will set new standards in creative thinking and divining ways to get rid of the older jets and buy more F-35Cs as the older jets obsolescence becomes more obvious.


Do you believe the Navy’s current and planned force mix of tactical aircraft is sufficient to meet current and future threats around the globe, and most especially in the Asia-Pacific theater of operations where the “tyranny of distance” is such a major factor?

Currently, I do. There are capability, inventory, and readiness aspects to delivering the required force mix. If I was ever to be confirmed as CNO, I would work with leadership to determine the best options to pace the threat in a dynamic security environment. The fiscal environment will bound the scope of our efforts, and so I would urge Congress to work harder in creating a fiscal environment that will provide for all of our Constitutionally-mandated needs.


The Secretary of the Navy recently remarked that he believed the F-35 should be and would be the nation’s last manned fighter aircraft. Do you believe this to be true?
If I were to be confirmed as CNO, I would work with the Secretary of the Navy to aggressively advance the development of unmanned systems. It is crucial that we push the boundaries of what unmanned technologies can achieve; the next generation in tactical aviation will play a large part in this transformation.

Having said the above, let me also observe that the Secretary has all of the technical knowledge and expertise in all the relevant knowledge areas and disciplines, with the liberal-arts and legal education sufficient to have once been a competent junior ship’s officer. I’m sure he was a very fine surface warfare officer, once upon a time. His thoughts and opinions on the subject of UAVs carries all the commensurate weight that comes with such an accomplished background.

I thank the Committee for their interest. Now go away.
