    Not to drift too far off topic, but I’ve always loved the idea of a combined Buccaneer/Super Tiger airgroup on a Clemenceau-sized hull. In retrospect, this seems like the best value-for-money for non-US navies in the 1960s, and **might** have been affordable enough for the RN, RAN and RCN to retain conventional carriers well into the 1980s.

    Buccaneer: At least as good a striker as the A-6
    F11F-1F Super Tiger: A Sparrow-capable version was being offered – a better fighter than the F-8 and much more carrier-friendly than the big F-4.
    Clemenceau-sized carrier: About as capable as Ark Royal/Eagle (in terms of airgroup size & aviation fuel capacity), but much cheaper to operate.

    I could see the RN choosing the 1954 medium carrier design (35,000t, i.e. almost a Clemenceau clone), and ordering 2 CV-1954s (later increased to 4 when CVA-01 proves unaffordable), 2 of which survive into the 1980s with the others passed on to the RAN and RCN around 1970:

    CV-1954 #1: Replaces Victorious (un-modernized) in 1959
    CV-1954 #2: Replaces Eagle (un-modernized) in 1962
    CV-1954 #3: Replaces Centaur & Ark Royal (no Phantomization) in 1966
    CV-1954 #4: RN decides not to replace Hermes. Construction continues for RAN, replacing Melbourne (no refit) in 1970.

    RCN purchases CV-1954 #1 circa 1970 to replace Bonaventure.

    CV-1954 airgroup (hypothetical)
    14x F-11F Super Tiger (or Sea Vixen or Crusader) – replaced by 12x F/A-18A in early/mid-1980s
    20x Buccaneer – replaced by another 12x F/A-18A in late 1980s
    5x Gannett or S-2 Tracker
    3x Sea King

    I understand the logic for delaying the first production A400M, but the 3 year certification timeline seems a bit excessive by today’s standards.

    In fact, the flight test program was initially planned to last only 21 months, so something big must have changed in Airbus’ planning assumptions in 2009 to cause an extension to 36 months. Funny how they blamed the entire 3 year delay on engine certification issues, when that was clearly not the whole truth.

    And sure, you don’t want testing & production to be too concurrent (see: 787 & F-35), but surely at this stage the engine design and major structural/aerodynamic components have been frozen, and those long-lead items could start production. Isn’t most of the remaining testing around equipment testing and drafting SOPs, which would only lead to minor changes in the fit-out that are easier to deal with late on the production line?

    From what I read, civil certification is expected towards the end of 2011, after 2,700hrs have been flown. Military certification towards the end of 2012 (i.e. right in time for the delivery of MSN007 to the French Air Force), after 3,700hrs. The flight test program will continue somewhat beyond that, since the total test plan calls for 4,370hrs.

    What I don’t understand is the 12-18 month gap between the deliveries of the fifth & final prototype, which is close to production-standard (MSN006: mid-2011) and the first series aircraft (MSN007: December 2011, though that may include a few months for customer acceptance testing). Given how well flight testing has been going so far, couldn’t MSN007 start building now so that the delivery could be be moved up to early 2012?

    A400M completes 2010 ahead of schedule

    The A400M fleet has surpassed 1,000hrs, and Grizzly 4 flew for the first time today!

    http://www.airbusmilitary.com/PressRelease/tabid/133/ArticleId/117/Fourth-Airbus-Military-A400M-makes-first-flight.aspx

    Interesting tidbit #1: Airbus says flight testing is on schedule, but in fact they seem to be ahead of schedule, since the target for 2010 was said to be 900hrs (Infodefensa.com article from August).

    Interesting tidbit #2: A400M flight testing has definitely accelerated. Since October, each Grizzly has been flying 18 flights/60hrs a month, compared to 10 flights/33hrs a month before October.

    Interesting tidbit #3: The 787 flight test program is still progressing slightly faster than the A400M, even with the recent grounding: each A400M averaged 12 flights/38hrs a month over the past year, versus 15 flights/46hrs a month for each of the 6 Dreamliner prototypes.

    Interesting tidbit #4: Looking forward, the flight test program appears to RAMP DOWN! 😮 Only ~1,700hrs in 2011 and ~1,000hrs in 2012. That’s 10 flights/32hrs per aircraft per month in 2011 and 5 flights/16hrs in 2012. Are they all going on a nice long European vacation? :confused:

    The simplest solution would be take the Atlantique 3 plans out of the drawing board again.

    This was a mix of new-build & refurbished ATL2s with glass cockpit, new sensors and new engines (Rolls-Royce AE2100 as on the C-130J, C-27 etc). I guess the UK could donate the Nimrod’s electronics, the French could donate the airframes, and both could split the cost of the refurbishing and engine buy. The latter could be structured as an addendum to Rolls-Royce’s support contract for RAF C-130Js to benefit from volume pricing.

    Would be cheap enough in relative terms, but I doubt that it would be cheaper than simply moving forward with ready-to-fly Nimrods.

    The F11F Tiger and Etendard IV/Super Etendard. Both widely ridiculed for short-legs and poor performance, when in fact they were excellent, highly maneuvrable and low-drag airframes with good transonic performance.

    With the right engines (more powerful & less thirsty than the J65 & Atar), they would have been excellent performers – probably superior to the F-8 Crusader in dynamic performance and range – and worthy predecessors of the F-20 Tigershark & Gripen.

    Provided it gets off the ground anytime soon the Chinese Y-9 may be a better solution than the KC-390. It has a larger payload, greater range and would undoubtedly be cheaper.

    http://www.sinodefence.com/airforce/airlift/y9.asp

    Witcha, those specs seem outdated. Here’s a more recent set of specs for the Y-9, and they’re a lot less impressive: cnair.top81.cn/Il-76_Y-8X_H-6U.htm

    Notice that the MTOW is only 65t (~15t less than a C-130J or KC-390), max payload only 20t, and max range with 15t only 2,200km. By comparison, the KC-390 is claimed to fly 2,500 nautical miles with the same payload, and the C-130J 2,800nm.

    The Y-9’s rather poor specs are actually quite surprising, given that it’s supposed to have larger engines than the C-130J (5,000hp vs. 4,700hp).

    With an operational F-12B, one shot of just one of its AIM-47 would do the job. Why would they want or even need to re-engage a target – or targets??:confused: Since the air to air missile AIM-47 Super Falcon was nuclear-tipped, it could more than destroy a single target. It could even have taken out a whole squadron of invading bombers; attack aircraft; and/or their escorts with one missile shot. With nuclear rounds such as this there would be no need to re-engage the target. So my question again – why would it need to re-engage:confused: And the more than Mach 4 closure rate is almost insignificant as a consequence. 😎

    The AIM-47 had a conventional warhead, and was semi-active guided so a F-12B would probably only be able to destroy one or two targets in one pass and would have to turn to re-engage. The solution to that problem would have had to wait until the mid-1970s with the active guided AIM-54 Phoenix.

    Why not? Lockheed certainly designed it as such.

    Maybe a question of opinion, but in my mind the traditional definition of “fighter” means the ability to do interdiction/escort over enemy lines. Don’t think the F-104 had the legs or maneuverability at subsonic speeds to do that, it was tailored for the quick-reaction interceptor role. IMHO the F-8 better meets the definition of a “fighter.”

    Not suited? Why not?

    IIRC, the F-104’s record as a ground-attack aircraft in Vietnam was less than stellar.

    Why not? It was quite successful in demonstrating that capability. The problem wasn’t the YF-12…it was the lack of a threat.

    What’s the engagement window with a Mach 4-5 closure rate? I can’t have been more than a few seconds, which makes me wonder about the effectiveness of the Mach 3 interceptor concept. And could the F-12 have slowed down & turned around fast enough to re-engage?

    IMHO, the F-111 would have made a good long-range interceptor for the USAF, either in F-111B form or even better as a F-111C with F-111B avionics.

    I’m not sure what you mean by “misunderstood”, but there’s no shortage of candidates:

    F-111: Fighter designation, Mach 2.5+ & internal gun, except it wasn’t a fighter.

    F-104 & English Electric Lightning: Blistering climb & acceleration performance, but so optimized for the interception mission I hesitate to call them “fighters”. (Same goes for Mig-25 & Mig-31) And really not suited for the low-level strike mission, but still used in that role.

    F12: I still can’t believe that the Blackbird could have made a viable interceptor.

    Mirage 2000: Too many people see only a jazzed up Mirage III, without understanding the fundamental differences that make the Mirage 2000 very competitive with the F-16 in A2A and actually also quite competitive with the Tornado in A2G (the Tornado despite its powerful looks is actually rather underpowered and ends up having no range advantage over the Mirage 2000 due to its gas guzzling afterburner).

    The Jaguar M was fundamentally unsuited as a carrier aircraft.

    • It was under-powered in dry thrust, so it had to rely on AB for take-off and climb, burning so much fuel in the process that it had short legs.
    • Landing characteristics weren’t great, with concerns about bolter ability due to the lack of power and high wing loading/approach speeds.
    • The downward angled afterburners spelt trouble for carrier decks – the French would have had to reinforce their carrier decks, for example.
    • And no radar so it couldn’t do maritime strike, unless you wait until 1980 for the Jaguar International.

    Super Etendard was actually a much better airframe, only let down by its engine. Had it been equipped with an RB.199 (available 1979) or even better an F404-GE-400 (available 1980), it would have been a stellar performer. Both the RB.199 and F404 were smaller and lighter than the SEM’s Atar, with 40% greater thrust and lower SFC.

    The SEM could have been a modern F11F-1F Super Tiger, or using another analogy, like a carrier-capable, strike-optimized F-20 Tigershark.

    Pay no attention to German reports – it’s always the same tired story: the new piece of kit isn’t working, it’s missing critical equipment (that somehow no other partner country has a requirement for) etc etc. This goes on for several years, while meanwhile everyone else has successfully fielded the same kit!

    I give you as examples the Typhoon and Tiger. A400M is heading down the same path. IMHO, it’s German inflexibility that’s the problem, not the A400M. (Apologies to all Germans on this board – I’m not stereotyping, just reflecting on the processes in place ;)).

    So have the weight issues been worked out or is the payload capacity being reduced? Will it still be able to carry 37t as advertised?

    No, but the question is how far from 37t it’ll be. All we know is that the payload will be reduced by 500kg (French MoD, March 2010). We don’t know whether that’ll be subtracted from the 32t contract spec, or from Airbus’ 37t figure. Airbus was still advertising a 37t payload at the Singapore Air Show in Feb. 2010, so who knows?

    So far the only capability that has been officially dropped is automatic terrain following, which no other transport aircraft has. Everything else is speculation or worse-case scenarioitis.

    What’s interesting is that once you subtract the €10B+ in development costs, you get a flyaway cost (including initial support) of ~€90M ($125M), compared to $240-280M at a minimum for the C-17. Let’s round-up to $140M, since EADS has to pay back the export levy. THAT’s how low EADS can go if it really wants to get a USAF contract.

    Triple good news

    A400M On Schedule, Costs Under Control & Record Week

    For those who find this expensive, the first 170 C-17s built cost about $380M (€300M) (R&D, production & initial support) in inflation adjusted 2010 dollars, and that excludes several billion dollars in post-production modifications needed to give the C-17 “tactical” capabilities. :p
