    You are a monomaniac when it comes to this subject. Truly. And this attitude will more reflects to virgin eyes what is bashing the way you do it than anything else. If you can’t accept simple metrics and stuck on a syntaxical error while occulting to yourself an order of magnitude difference in yearly production number, that’s a problem.

    As you know, I did thanks you briefly for correcting my post quite instantly, so all egos are safe (and nobody bother – catfights are better illustrated and fought in the mud) . 😉

    second Sikorsky S-97 Raider flying – hover, low-speed maneuvers and up-and-away flying

    Longer video of second @Sikorsky S-97 Raider flying – shows hover, low-speed maneuvers and up-and-away flying with propulsor turning – coaxial rigid-rotor compound X2 configuration combines high speed with helicopter’s low-speed agility and some unique capabilities using the prop

    I don’t know but still, we have this:

    the Committee is dismayed by the inaccuracy of the initial JPO estimates,” the report says.

    Pentagon, Lockheed Martin Close To Securing F-35 Lot 11

    The Pentagon and Lockheed Martin are nearing a deal for the 11th lot of F-35s that includes more than 130 jets, multiple congressional aides say.

    just to scale it, that’s in one single year ten years of laboriously negociated Dassault production with the said maximum sustainable output…

    ———–
    Also, the JPO was apparently just proved wrong on its own field:

    Further, the report reveals a recent analysis from the Pentagon’s Cost Assessment and Program Evaluation (CAPE) office on economic order quantity cost savings. The JPO estimates it would save roughly $1.2 billion for the U.S. and partner nations in fiscal 2018 and fiscal 2020. The program thinks roughly half of the savings would go toward the U.S. aircraft buy.
    But CAPE’s analysis concludes anticipated U.S. savings would be about $300 million, which is about half of the JPO estimate.
    “While these savings are still significant, as certified by the Under Secretary of Defense (Acquisition and Sustainment), the Committee is dismayed by the inaccuracy of the initial JPO estimates,” the report says.

    it’s all about feeding the lift fan with enough air and so, it acts effectively as a giant airbrake, or more precisely as an air stream router. Given that the load on the actuating jacks are fairly easily known, I doubt there would be a problem with it* that could be related to the design. We are dealing here with relatively benign flight conditions (low alt / slow speed).

    The F-111 had a giant airbrake too on its underbelly that was seldom proved to fail.

    *there are no visible sigh of any vibrations

    Senate Approps Joins House Boosting F-35 Buy; State Warns Turkey On JSF

    The damage of the purchase would cause damage to Turkey’s relationship with the United States and NATO that is “difficult to repair,” assistant secretary of State Wess Mitchell told the Senate Foreign Relations Europe and regional cooperation subcommittee.
    “I think we can’t be any clearer than saying that, both privately and publicly, that a decision on the S-400 will qualitatively change the U.S.-Turkish relationship in a way that will be very difficult to repair,” Mitchell said. “We’ve been clear on multiple occasions with the highest levels of the Turkish government that there will be consequences,” he said.
    […]
    Air Force secretary Heather Wilson said the deal “does present some operational problems that we’re discussing with Turkey…particularly as it relates to the location of advanced aircraft in Turkey. We would not want to have that aircraft close to the S-400.”

    Turkey overall surface is 783 562km²

    S-400 best radius of action is 400km, hence a single system covers Pi*r²=3.14*16.10^4=500 000Km², what represents 64% of all Turkey territory.

    Add, mountainous ridges, range into enemy territory and you’ll probably have 30/40% of Turkey covered by a single S-400 system.

    Hence, in a naïve vision of things and a simple theory interpretation, there might be some tight room left for both systems… According that you have strict OP rules and a clear understanding of both country interests.

    The art of the deal, they say!

    I don’t know if this has been posted already:

    The purchase of Typhoon will also allow the Belgian industry to participate into Scaf

    General Manager of Airbus Defense and Space (ADS) -Belgium, Eric Lardinois:

    “A participation into Scaf program (in English FCAS for “Future Combat Air System”) is not solely related to the selection of French Rafale, as suggested by Paris.”

    Yes but much cheaper… Certainly that cost was the big point of the tech refresh 😉

    More reliable suggests also less cooling needs on average.

    LM could plan to offer a naval version of the T-50 to replace the T-45:

    If the T-50 fails to win T-X, Carvalho [Lockheed’s executive vice president of its aeronautics division] said, Lockheed will look for other opportunities to help KAI sell the aircraft in the international market. One possibility is the eventual replacement of the U.S. Navy’s T-45 trainer jet, although the companies would need to ensure that the T-50 could be qualified to land on a carrier deck.

    I think you are right 3K kph is Wiki cited top speed (Su15 should have been slower).

    And to push the nail even further (quoting my self from this old discussion ):

    In my memory the Su15 was fast: 2.4 or 2.6

    The culprit will cease any more Flago(r)n(erie) for the day 🙁

    Don’t Forget the exceptionals performances of the Flagon, notably the Mach2.8 max speed that would give him all the dynamic advantages offered by speed in BVR.
