    From my time at RAF Bentwaters I know that the F-117 visited the base well before its was publicly unveiled.
    While I did not see it and was not involved with it or directly told of its existence, one learns things by keeping your ears open at the command post.

    Yes, it was unveiled to the UK MoD in 1983.

    That one can’t have circulated very widely and must have been confined to a few places where speeches were given because I hadn’t seen it until now. So I doubt it affected the outcome.

    What I don’t see is a substitute for the F-35B…

    Buy a Harrier production license from BAE?:highly_amused:

    Wow, that sounds very conclusive, do you think is that serious? Do you mean a definitive abandonment of F-35 program?

    And how is Turkey expected to substitute the gap left by the F-35, is there a plan at all that you know? I mean, apart from AF you were expecting to buy the STOVL version too for the navy, right?

    The J-31 is about the only other game in town that’s going to be available in the next 15 years. Su-57 maybe? But I’m not sure they’ll get technology transfer or operational sovereignty there either.

    Well Metric wave band radar is essentially immune against ARM by the fact that no interferometric antenna of metric waveband can fit inside missile. The fighter may need usual land attack missile.

    Regardless the detection claim is unfortunately sketchy especially regarding to frequencies being used, target aspect, environmental condition especially presence of multipath which may affect apparent RCS. One caveat however is that usually during peacetime F-22 is equipped with luneburg lenses.

    They don’t need to fit inside the missile because AARGMs have MMW terminal guidance too, all it needs a rough steer from the energy of the transmissions, or from the launch aircraft. The other problem with these large metric radars is that they tend to be stationary, so even a cruise missile can target them.

    WU Qian Ji, head engineer at CETEC officially confirmend that in 2013, metric radar could follow a F-22 at 450 Kms. This type of radars now cover the entire coast of China and are precise enough to target.

    Take it with a pinch of salt, sill…

    Not that impressive, the radar on a Type 42 destroyer could follow an F-117 at 240km. But all these figures are without jamming and pertain only to detection, not targeting. So in hypothetical future war scenario, a stealth aircraft will simply fly in, fire an AARGM-ER and remove these radars.

    Was this the claim referred to earlier?

    No, that is doctored. Here is what the bus said.

    What are you hoping for, St John? That we do something potentially damaging but so quickly that we also do it in an ill-prepared and half-arsed way?

    If we’re ill-prepared after 33 months, who’s fault is that?

    An expected late 2019 Milestone C decision will likely push the “enacted” to over 100 aircraft by FY21.

    Are those figures just for US or total?

    Hell, the sale pitch to many customer looking at 4/4.5 Generation Types. Is they will be obsolete and you must have a 5th Generation Fighter like the F-35. Yet, then the US goes out and buys more 4th Generation Fighters. The F-15 Eagle even dates back to the 1970’s! :confused:

    Boeing lobbies hard. I’d put the purchase more down to political corruption than good sense.

    You have got me confused now Deino, Why was it that the J-20 won when SAC’s proposal was much better? Is this the Chinese equivalent of the ATF program where the better plane lost. :confused:

    The YF-23 lost the ATF program because of McDonnell Douglas’s performance on the A-12, just as Convair lost to the SR-71 because of the B-58.

    This find of 2012 🙂
    F135 dry engine weight – 1701 kg
    “not to exceed weight” for CTOL/CV – 2950.16 kg
    “not to exceed weight” for STOVL – 4750.02 kg

    The mass of the “power plant” is about twice the “dry mass of the engine”

    It’s always the dry weight that is quoted though.

    Never thought about cost being a factor with a stealthy SPEAR 3, in comparison anyone know the total cost of the Storm Shadow cruise missile?

    £790k in 2011.
