    I can’t find any hard figures on a first look but I’ll check my books again later.

    What I do remember us being told on a visit to Leuchars soon after the ADV arrived:
    1. It could out-accelerate anything in NATO short of an F-15
    2. The stretched fuselage had lower drag than the IDS; in fact it was proposed to Japan as an IDS+ for their F-X competition
    3. It could out-turn the UK-Phantom at all speeds and altitudes and the Lightning in some regimes
    4. It could out-roll a Hunter and catch it in a scissor

    Instantaneous turn rate should be similar for the IDS and ADV since that measure is lift-limited. Sustained turn should favour the ADV with more thrust.

    It doesn’t really matter which airframe France and Germany choose. They’ll not sell many of them outside their own requirements due to Uncle Sam’s mighty FMS program.

    Why pay hard Euros for an MPA when you can get a P-8 within 6% of the US Navy’s cost on a nice 60-day-after-delivery zero-interest repayment schedule?

    It’s just a national-pride exercise, when Japan has a perfectly good option available.

    My favorite guess today would be toward a Q400 derivative (Airbus bought Bombardier and this airplane has much better performances to fulfill the role than the sluggish ATR-72 does).

    Airbus haven’t bought Bombardier. The Q400 is not associated with the Airbus-Bombardier-Quebec C-Series venture. There have been a few integrators offering their systems on an MPA variant ( SAAB, L3 and IAI ) but no-one has shown interest as yet. And frankly with Bombardier’s constant state of semi-failure no-one knows if the Q400 will even be available by 2030.

    I don’t see the A400M being a contender, traditionally MPA conversions of transporters have sold in single-digit quantities. They’re just the wrong shape for a dozen crew at low-level.

    To me it would be logical to go in with Japan on the P-1 instead of splitting the non-P-8 market even smaller, but in the end it’ll probably be something boring based on the A320 or C-Series.

    Because the film had to incorporate significant flying scenes involving the McGregor brothers there was not much choice but the Lysander although the Blenheim had also been on the list of flyers.

    Another option would be to express dissatisfaction and walk away from the project.

    TV producers will keep making shallow, character-focused, unchallenging ‘entertainment’ so long as people keep compromising to meet their ‘vision’. Maybe someone needs to point out that their vision sucks.

    MiG-31 was a good match for the vast Soviet hinterland but other than Canada and perhaps Brazil ( but what enemies? ) I can’t think it would be terribly useful or affordable anywhere else.

    Most Western nations were happy enough with Nike Hercules SAMs to sweep the upper atmosphere to 150,000ft, and single-seat fighters for everything else.

    Not technically a ‘load’ but 48 B61s in one hangar seems a lot of firepower.

    in reply to: Could the RAF have bought F-22? #2165799

    No. For one thing, the F-22 isn’t export-cleared – its systems haven’t been secured against leakage

    Neither was the F-117, but it was also offered to the RAF. As was the B-1B.

    Never ever heard that the RAF lobbied the RAF against acquiring the Viper in the nineties, and never ever read anything that sugested that the RAF ever considered the acquisition of whatever version of the F-16 for the Phoon missions.

    I humbly suggest that perhaps you didn’t read enough. The “F-16 for RAF” was a fairly stable rumour from the mid-80s onwards, until about 1995 or so. Bear in mind that there weren’t really ‘Phoon missions’ in the RAF of the 1980s; other than close-support, everything was geared to two-seat long-range all-weather operations.

    There was a contingent that favoured replacing the miscellany of tactical single-seaters ( Harrier, Jaguar, Lightning ) with the F-16 and reducing costs in that area so as to enable focus on the core interdiction & interception missions. There was even a senior officer with the car registration plate “F16ONLY” or similar.

    The Typhoon wasn’t a good fit for the RAF’s role, and still isn’t. Grudgingly I have to admit that the Phantom-sized F-35 is probably a better fit.

    Leonardo reveals new ‘weapons-wing’ for Lynx Wildcat

    I can only imagine what detrimental effect that’s going to have on hovering performance. The chord of the wing looks enormous, two big flate plates interfering with the downwash.

    Oddly the article doesn’t mention the advantages. I suppose it generates lift to help offset the weight of weapons, but why not use a lighter extended pylon? Basically just the spar of that wing.

    I like the Mirage F.1 suggestion. I’d go for the F.1-M53, an excellent all-around performer. Mach 1.2 at sea-level; 50,000ft and Mach 2.2 in 8 minutes. 8.6g subsonic limit, 7g supersonic.

    Plus the French like to sell aeroplanes and will usually find a way to do so as long as you put the cash on the table. In contrast I can imagine the USA’s response if Diddlystan or the People’s Republic of Noodlenoggin sumitted an FMS request for F-15s…

    “Your registration to this event acknowledges your agreement to not share information or materials obtained at the event with the media, and certifies that you are not a member of the media,” the form noted.

    That’s a pathetic attempt to keep the process opaque, and also one of the weakest NDAs I’ve ever seen. I’m only a a medium-level in IT projects but even our NDAs don’t have such obvious workarounds as that.

    “We didn’t speak to the media but it seems the janitor found our tender document in the dumpster…”

    ZA717 was one of a pair of RAF Chinooks that ate their own rotors within the space of two days in 1989 due to a manufacturing error in part of the dynamic train, hence why it was never upgraded. I think the other one was reduced to produce.

    giving more credence to the idea that collaboration with the Germans in the post-cold war era is a bad idea..

    Well given the excellent history of Bölkow’s helicopters it might have been better for everyone if the Bo 125 hadn’t gone multinational…

    As originally proposed as Euro-UTTAS. But then each customer country wanted some input and workshare and we ended-up with the redesigned-by-committee NH.90

    Interesting topic and issue, these days you can chart the flight path of any aircraft using their transponder.

    Many aircraft, but not *any*. Mode-S can be turned-off on operational missions, or on training missions that mimic operational profiles. We see this frequently in the UK on Typhoon quick-reaction alerts, where the tanker is visible but only one or sometimes no Typhoons are broadcasting.

    And then you get into interesting tricks such as deliberately feeding bogus Mode-S data to systems that you think your opponent might be watching.

    And large proportions of military aircraft and small private aircraft don’t have Mode-S transponders at all.

    Not very colourful but an unusual variant. US Army testing Kaman UH-2A Tomahawk in 1964.
