    Certainly that is what a couple of agenda driven guys in the media would like people to think.

    I don’t doubt the USAF is already starting to consider future versions of the F-35 and now 6th generation clean sheet designs. That is simply part of the business of staying ahead of the curve. It doesn’t mean the current version of the F-35 is somehow deficient.

    A mid life upgrade of the airframe would be a good think to fight against large numbers of PAK-FAs and chinese stealth fighters. USAF officials have said that they have been surprised to see how quickly the potential opponents of the F-35 have turned out to be. And don’t forget that the F-35 was not meant to be an F-22, and that the plane in around 7 years late.

    Research on graphene is progressing quickly too.

    They have done a significant breakthrough last year on how to manufacture graphene:

    This is the DEAN MUSKETT photo 500% enlarged.

    The rear of the plane doesn’t look much like on the drawing however. It might be another prototype.

    A supercruise of M1.2 would already make it incredibly hard to intercept, and would not cost much

    That would be a good capability indeed. And top speed would not matter much.

    Also controlling it without tails at mach 1.2 might not be too hard versus at much higher speed.

    It might be this one indeed. Maybe they are already testing prototypes.

    The USAF might want a larger plane with 2 engines to replace the F-22, but a potential upgraded variant of the F-35 with a tailless delta would keep the F-35 relevent for longer. It seems like the USAF is beginning to think that the F-35A will be a bit limited against the next generation of adversaries.

    This design is interesting because at the same time the fuselage is long so the bay can be long, and the mach angle may allow for a supersonic speed. It might be a good cost-effective compromise.

    Let’s say the aerodynamics is fast enough to allow supersonic speed with that design, how much more would it cost to exploit that capability and make the aircraft supersonic? The afterburner system would not cost a lot I guess. Would they have to reinforce the structure? Also would the aircraft be harder to control in yaw at supersonic speed?

    That’s why if they can install the engine on the F-35 they should consider seriously building the F/A-XX from the F-35 if possible.

    If it is this one, maybe it will have a supersonic dash capability.

    Maybe the USAF would be interesting in having a mach 1.4 or so speed.

    Won’t the ADVENT and AETD engines necessarily have a larger diameter, given that they have a third stream of air flow? If yes it wouldn’t be that much of a problem for a single engine fighter because the fuselage is always rather wide, but for a dual engine fighter it could lead to an excessively large fuselage.

    There is a solution that seemingly isn’t being considered.

    Vertically deployable tail for the higher AoA stuff when you need it – you already have suitable storage spaces alongside the engines and behind the rear wing spar. If your maneuvering hard, then your already discovered and signature isn’t critical. Furthermore, there is nothing to stop you deploying them above or below the airframe, depending on your maneuver, so that large actuation envelopes are not needed to exert considerable control authority.

    Probably quicker, cheaper and better aerodynamic fix than all the control hoops that they’ll need for a tailless solution – albeit with a slight weight and maintenance penalty. But the vertical tail would not be high-g rated items – so its not quite like the swing-wing complexities of MiG-23, Tornado or F-14.

    I had the same idea for the vertical tails. 🙂

    Canards could also be deployable ( for a delta plane they would be deployed for dogfighting and for landing on the carrier ).

    Thank you, that’s pretty cool. They probably need some kind of 3D TV for a tailless delta, for a fighter at least. Without a breakthough in tailless deltas, I doubt the next fighter will be much better than an F-22 in terms of speed and stealth.

    As for the F/A-XX, maybe LM will come up with a tailless delta the F-35 with a fluiditic LOAN exhaust.

    I believe I had seen a design of 3D stealth thrust vectoring system some time ago. The nozzle had 4 ‘petals’ vs 2 on the F-22 for instance. Sort of rectangular. Does that remind you of something?
