    Funny someone should mention Concorde.

    The program has been under full-scale development for ten years. It was supposed to be in service by now, but nobody can guarantee a date. About four years in, weight and performance problems led to a complete redesign so the first prototype was not representative.

    But the press releases inform us that flight testing is going well and all the world’s leading operators have signed commitments. How can they be wrong?

    The opposition to the project is confined to a few journalists and a handful of independent analysts who claim that its acquisition and operating costs will be unaffordable and that its very expensive technology is advantageous over a small range of likely missions.

    They’re clearly misguided fanatics.

    Enough of this malarkey. I am now jamming people who contribute nothing but wind here, and advise others to do the same.

    PS That comment about Paul Bevilaqua was hilarious, for reasons that I am not at liberty to discuss at this time.

    Mr One Post

    The most highly regarded general staff of its day brought us World War 1 because their brilliant two-front plan was unworkable.

    Around the same time, the most technically advanced navy in the world was proudly commissioning the battlecruisers that exploded at Jutland.

    Professionals brought us the K-boats, the Defiant and Bomber B, and the Maginot Line.

    The united military-technical might of the US has been trying to create an all-stealth combat air force for 27 years, resulting in 160 combat-capable stealth aircraft that cost huge sums of money to maintain and upgrade, and a USAF front-line force that is older than any in history.

    And guess what, the people taking those decisions were all professionals.

    Why don’t you read some history instead of fanboy message boards?

    A Viper on steroids?

    Yes, it grew breasts, its testicles shrank and it attacked people without warning…

    Freezing assets? All it would take would be for a few secret account details to get accidentally Wikileaked. :diablo:

    “O this I have read in a book,” he said, “and that was told to me,
    “And this I have thought that another man thought of a Prince in Muscovy.”

    The story by Le Matin – which has consistently been puffing anti-Gripen since Dassault lost – is about that well sourced, and the AvWeek quote is distorted.

    At least Spear (like SDB II) is mostly a cylinder, so its internal carriage efficiency doesn’t suck as badly as Aero 1A (the Mark 80 shape).

    Personally I rather liked the Have Dash & Have Slick concepts of the late 1980s, for getting to very low RCS when you needed it, without carving out a ruddy great hole in the middle of something that is as densely packed as a supersonic 9g aircraft needs to be.

    It also gets to be a bit of a dog’s breakfast when you have to design a weapon bay around a bomb that was designed for low drag when carried outside (by the A2D Skyshark, I recall). If you were serious you’d design bombs with a rectangular or triangular section, and constant width along most of their length, because they pack better.

    Not always. If I have a radiating pattern from a prox-fuzed frag warhead, a flyby may place more of that pattern over the target’s most vulnerable points.

    A500 –

    Seriously, impact is always a possibility, even if the missile designer wants a fly-by trajectory to maximize warhead lethality. The probability rises as the missile gets better in the endgame. And you certainly don’t want to try your test against the AA-Stunner aka Python 6, which is HTK and has no warhead.

    So while I understand your frustration with long-range AAMs, which have historically been oversold, this particular test is not the way to go about it.

    Meanwhile I join in the merry larfter as another specimen of trolliculus Australiensis is gin-trapped by his own faulty logic…

    BVR does not involve IIR? I would not make that statement so categorically. News to the MICA IR, ASRAAM and AIM-9X people, particularly AIM-9X Block II with datalink.

    My interpretation of what LockMart is saying is that more than four internal AAMs of any type will require some new and smaller missile (there is one under study for well into the 2020s).

    http://www.flightglobal.com/blogs/the-dewline/2011/05/graphic-beyond-amraam-aim-9x.html

    And you can look at the historic timelines for missile development – and at the US industrial base and experience in high-speed missile development – and take a guess at when NGM might be ready.

    It’s succeeded JDRADM as the F-35 fans’ magic weapon that will go 200 miles, pack six per bay, and take out everything from a spaceship to an aircraft carrier. Which is all wonderful, but there are nearer-term issues to address, such as finding a supplier closer than Norway for reliable AMRAAM motors.

    No, Potato-Head, Boeing might have considered the investment (not necessarily in the triple-digits) in the light of opportunities beyond Japan’s initial 42 aircraft.

    Spud – Boeing would have paid for it. And if they thought that there was more benefit to be had form having the option, they would not have charged Japan the full price. The Japanese argument is bogus.

    Are you really buying into the ability to run RCS measurements from photos? Read APA much? 😉

    Nice try with the ol’ ultrasonic troll-whistle of dragging APA into it. Of course RAM/RAS is a factor, but it is not the main driver, and furthermore there is a most-likely band of RAM/RAS performance, given limits on thickness and weight.

    So given an accurate external geometry (which indeed is obtained from photos, and why not?) it’s possible to establish RCS within reasonable bounds – as, indeed, it’s possible to establish most performance parameters.

    [QUOTE

    25-30 years assumes they have any clue as to the F-22’s or F-35’s true RCS and what it is capable of in terms of electronic attack.

    Because the added cost to develop and test would drive the cost up, which is the point to the Japanese comment.[/QUOTE]

    Since the four principal contributors to RCS are “shape, shape, shape and materials” (Denys Overholser) and neither the external shape of the aircraft nor Maxwell’s equations are classified, to doubt that an adversary has “any clue” as to the F-35’s RCS level would seem to me to be an exercise in over-confidence.

    Maybe there is some built-in technological EA surprise (other than the X-band front-sector EA from the APG-81), but there isn’t any evidence for it.

    Yes, a refueling slipway would cost money, built into the price. But a deciding factor across the program? Sorry, but no.

    The wording on the Q&A site is more recent than the Skunks’ claim to have hacked the six-missile problem.
