    Of course, saving weight in the radar raises another issue…

    Never fear, I’m sure LM will find a way to scale down the electromagnetic spectrum.

    Apertures, power and cooling are major drivers in avionics weight. Processors, not so much.

    More on F-35s to Farnborough, including an unusual target set. Reuters via Chicago Trib.

    Step backwards, and you’ll see most of the world’s armed forces in a similar condition: With generally lower fertility rates and rising economic standards, trained and experienced personnel are not cheap.

    Since people are always a huge component of operating costs, services are beginning to focus on those numbers, and rightly so.

    The JAS 39E, by heritage and by design, slaughters the competition in CPFH. Switzerland’s chief of the air staff said that it was half the cost of the competitors, neither of which will cost more to support than F-35. (Nobody today knows what F-35 will cost, including Gen. Bogdan.)

    If you have a 100-or-fewer fighter force today and don’t evaluate Gripen, you are an idiot.

    Rii, too, may take a cookie from my desk.

    As for, “no debate among professionals”,that would imply either that the CNO, CNAS*, Saab, RSwAF and others too numerous to mention are amateurs, or that anyone making that statement has not been keeping up on his reading.

    * Who is the boss of CNAS, and what is his next job?

    Oblig gets it.

    Loke, you are dead right.

    The E makes a lot of sense for countries that does not need or cannot afford the extra bells&whistles offered by the F-35.

    Which, unless the program pulls some kind of operating cost miracle out of its ear, is pretty much all of them.

    SRVL is not standard as far as I know. It is being adopted as a heavy/hot day procedure by the RN and is being evaluated by the Marines. It also involves airspeeds around 60 kt (30 kt relative to deck, plus ship speed and wind) which is considerably higher than most land-based “rolling VLs” – which are done to avoid debris and sometimes hot-gas ingestion.

    AM-2 works, but is horribly heavy to cart around.

    This discussion has been documented to death, but to keep it short:

    Navy civil engineers have concluded that the F-35B is likely to “spall” standard concrete (that is, break off the surface layer) in a single operation.

    They have specified continuously, bidirectionally reinforced pads of heat-resistant concrete for all JSF VL operations.

    Such pads have been constructed or contracted for at Yuma and Beaufort.

    VLs at Pax use AM-2 over concrete.

    There’s been discussion of “creeping VLs” to reduce peak thermal and mechanical loads, but no such operations have been seen on released video.

    Interesting perspective, and quite likely given French employment law and the fact that the flow of orders for a high-end fighter is most unlikely to be smooth.

    A failed attempt at sarcasm, I fear.

    Mind you, imagery of an F-35B (after six years of flight testing) doing a VL on anything other than a steel deck, AM-2-shielded asphalt concrete, or a reinforced, high-temperature concrete landing pad would be more convincing.

    Everyone has a first time out. But the B would be the most appropriate version and the logistics would be demanding. Not to mention paying for a new runway afterwards.

    Indeed Mr H. Gonna be a while before we see that puppy at Farnborough, methinks, despite the billions of HMG money riding on it.

    Swedish policy is generally more restrictive than US policy. And there is enough law and regulation surrounding the subject, I think, to prevent the USG itself from blocking F414 while trying to sell F-35. That would also **** off General Electric and you really really really don’t want to do that.

    It’s the tomtens.

    http://en.wikipedia.org/wiki/Tomte

    They leave the parts in the hangar at night and there is a fully completed airplane ready in the morning.

    The French tried it but the gnomes broke into the absinthe and it all went horribly wrong.

    As Loke says, the Swedes use a unique blend – buy, team or design – for components and technologies, and it varies from model to model (Volvo didn’t like being shut out of the 39E engine, Saab may do the radar for the C/D+) but with some consistent features (EW has always been developed locally and is related to a strong national SIGINT capability). The core skill is putting everything together from these diverse sources.

    However, the big thing is that everyone knows that if you can’t come up with a fixed-price solution that costs less than an import, Sweden will exit the business.
