    Despite having built the F22, LM has started from scratch with the F35. The two planes have nothing in common, airframe or the electronics. These make for two very costly programs. A cheaper degraded variant of the F22 would have make more sense, but why make it cheap of you can make it expensive ?

    Not really. The F-35’s airframe was dictated by the STOVL requirement, and so was always doomed to being a fat single engine airframe. On the other hand the F-35’s avionics are a vast conceptual improvement over the F-22’s. The F-22’s avionics are largely monolithic, because its architecture dates back to the late 80s when that was the only way to accomplish things like sensor fusion. The F-35’s uses a federated architecture — different modules talking to each other using well known protocols over a network — because that allows easy component upgradeability.

    It would not have “made sense” to build the F-35 the way the F-22 is built because you end up paying a lot more later to upgrade anything and having blocks of aircraft not compatible with each other — e.g. the Block 20 and earlier aircraft which will never be combat-coded because they can’t be upgraded to Increment 3.X.

    As far as it goes, yes, in the end IMO it would have been better to develop an F-22C with an F-35-like systems architecture, than developing the F-35 at all. Nothing says we still can’t do that; the F-35 development cost is a sunk cost, that doesn’t mean we have to keep throwing money at it.

    You don’t think it’s realistic for the USN to have 240 F-35s spread across 10 carriers? There hasn’t been talks about cuts of that magnitude. I don’t think there’d be enough votes in Congress, even among fiscal hawks, to gut defense spending by that amount.

    Supporting 240 front-line F-35Cs would require easily half again that number just in terms of FRS and aircraft in overhaul. The USN’s planned buy is 480 aircraft, which is enough to sustain that plus account for attrition. As the cost to procure and operate these aircraft keeps rising, it’s clear that this will never happen and the actual number purchased will be less than 300. Which is not nearly enough to sustain 20 VFAs worth of aircraft.

    …But if the F-35’s problems are NOT sorted in 2 years (cracking spars, etc etc), then what? and if Mr. Gates statements will now endanger the B-version?

    The cracking spar is a B model problem only, does not affect the A or C. Between issues like this and Gates’ “probation” statement that the B model is never going into production. Unfortunately that leaves the A and C versions saddled with design compromises that were made in the name of commonality with the B, all for nothing.

    As you can see from the X-35 pictures though (pretty much no such treatments at all), there is a smooth spectrum of LO sophistication from demonstrator to production. So depending on where in its development an aircraft is, this type of feature is a poor indicator of the ultimate goals in RCS reduction. Not completely irrelevant, but pretty unreliable.

    Right, no disagreement there. I was more responding to the notion that sawtooth edges are somehow “old design” and that modern VLO aircraft don’t have them. If the current T-50 prototype only has them in a few strategic locations (e.g. only where they actually affect mechanical and aerodynamic characteristics, like bay doors that actually open) it says nothing about their presence on actual production aircraft.

    As to the J-20, it does seem to have a more “finished” VLO treatment at first glance, at least in terms of sawtooth edged — e.g. the landing gear bay doors, engine nacelles, etc. But since we don’t know anything about the rest of the aircraft’s material construction we have no idea if this is really significant or just window dressing to impress the West.

    The program did shift, but not as a result of issues the C model was having to overcome. This is why the likelihood of Super Hornet buys being anything more than augmentation vs an alternative isn’t realistic. If we start seeing issues with C models, then it might be worthwhile to discuss, but so far all I hear are solutions in search of a problem.

    The Navy pretty much has to stick with the F-35C since there is no other carrier-capable VLO airframe in the pipeline. They are the only U.S. service that “needs” the F-35 at all. Even then, the most likely outcome is that they’ll be in fleet service in much the same numbers and role as the A-6Es were in the 1980s. The notion that you’re ever going to see two, 12-plane VFAs of F-35s in CVWs is pie in the sky thinking. The Navy is far from having placed its last order of F/A-18E/Fs.

    As far as the UK, they really would be better off with F/A-18E/Fs, if only so that they can afford to maintain a numerically significant force structure.

    Hey, zziggzzaggz, where are you?!

    Why would a mechanical and flight systems demonstrator, with absolutely no requirement for low observables, have zigzags?

    No need for new F-22s before 2020. 😎

    And then what? If F-22 production is allowed to cease, restarting it won’t really be an option by 2020. And we know how long it takes to field a whole new aircraft. Is it really a good idea to let production stop when we know that multiple new aircraft that obviously invalidate the DoD’s assumptions about force requirements (that the rest of the world would remain frozen in 1990) are going to go into production in this decade?

    Any further slippage? The A/C models are ahead of schedule right now, and nowhere near the situation of the B model.

    What schedule are you talking about? The A and C models made their flight test schedule for 2010, but the entire program was pushed back significantly in 2010. And that is before the F-35B pronouncement this week.

    Yup, stealth is not required for FAC-A and CAS. Marine Air exists to support Marine Ground.

    Exactly. And the Marines are supposed to be expeditionary. The Navy projected cost per flight hour of the F-35B and C to be over 60% more than that of the Harrier and legacy Hornet, which makes it over four times that of the Super Hornet. What that translates into is requiring more fuel, more spare parts, and more maintainers, which does not really improve your expeditionary capability.

    Maybe you should continue reading, because there is a good point there aside from premature comparison of the two birds. People who fly F-22, or order F-22s to fly war mission will never be in a fight on a home field.

    That fact, in addition with being outnumbered by J-20s alone, and 500 Generation 4 aircraft over China by 2020 is the point of the article IMO. Not one on one dog fight.

    Yes but that article isn’t about that. The piece is a bunch of speculative nonsense about J-20 specifics that are about as credible as my opinion on next year’s trends in women’s shoes.

    I think it’s all fine and good that the media is finally pointing out to the American public that we have been making stupid procurement decisions over the last 20 years and that it is now having consequences. But that doesn’t make dumbed-down nonsense any more interesting to read.

    military experts are warning that the aircraft – reportedly capable of besting America’s F-22 in speed and maneuverability

    And I stopped reading right there.

    The Additional Super Hornet are nonetheless replacing worn out Hornets. Regardless, if there USN and/or USMC. As for the latter buying Super Hornet your dreaming. Even if and the F-35B would be cancelled. (exteremly doubtful) The Marines would get F-35C’s and not Super Hornets….

    The F-35B is hanging by a thread at best, as Gates himself said this week. The USMC needs to recapitalize both their Hornets and their Harriers, and the best and fastest way to do that once the F-35B is canceled will be to buy Super Hornets. The F-35C doesn’t bring anything to the table that the Marines need any better than the Super Hornet does, but costs more to buy and operate. It’s a no brainer.

    I see. That the Tornado is faster, is no doubt. As for range, don’t forget that SH is a naval figher/striker. I red somewhere that the fuel reserve for naval planes is considerably bigger than for land based planes.

    It is, and the range figures being thrown around are apples to oranges anyway.

    Beyond that, the Super Hornet has more advanced avionics, more flexible ordnance, and is much cheaper to operate than the Tornado. Tornado was designed as a long-range interdiction aircraft and the Super Hornet wasn’t, so it is not surprising that it is longer ranged, but that doesn’t tell the whole story.

    The additional Super Hornets are to make up for the delays with the F-35B. As the USMC has several squadrons assigned to USN Carrier Airwings. (three deployed at the moment)

    No, the additional Super Hornets are to make up for the more-rapid-than-expected wearing out of the F/A-18A+ and C models and the delay in the F-35C. The planned CVW force structure was based on F/A-18A/C being SLEP’d to 10,000 hours and the F-35C arriving on time. Neither is proving true so they are finally forced to do something.

    This is all a result of the Navy being forced to sacrifice their air wings in the name of the F-35C. It started with the refusal to buy adequate numbers of aircraft and instead bolster the CVWs with VMFA squadrons under the TacAir Integration plan. Of course that was just filling the decks with more worn out and/or inadequately equipped airframes, which we are now wasting money on by SLEPing them at a high cost per added flight hour, when we should have bought new in the first place.

    In any event the problem will fix itself in a couple of years when the F-35B is canceled and the USMC buys Super Hornets.

    Also from CMF, a comparison of the size of the J-20 in relation to the J-10 and the ubiquitous JAC light truck.

    By this gauge this thing is about flanker size if not smaller.

    Comparisons like this are never valid. The truck would have to be exactly the same distance from the fuselace centerline in order for this comparison to be valid. It is obvious just from glancing at the shadows being cast that the truck is not the same distance from each airframe.
