    Boeing should offer the CF-15CA.
    What was the best choice in 1980 can’t be wrong today. Back to the Future!

    Collecting the necessary data is not a problem with single seaters. The 7+1 missions were basically check flights to confirm what has been learnt form docs and in the simulator.
    From https://www.vbs.admin.ch/content/vbs-internet/de/die-schweizer-armee/sicherheit-im-luftraum.detail.nsb.html/75494.html run through google translator:

    The flight testing included eight missions for each candidate, conducted with one or two fighter jets. Seven of the eight missions included given tasks. A mission could be chosen by the candidate to repeat one of the given missions or to demonstrate special features.

    The aim was to check the sensors in the Swiss environment, the compatibility with the technical infrastructure of Switzerland and the degree of maturity of the fighter aircraft. In addition, noise measurements were carried out by the EMPA in Payerne and in Meiringen.

    There are issues with not having twin seaters though.
    With the Swiss AF not operating advanced jet trainers, going from a PC-21 turboprop directly to an F-35 seems like a big jump.
    And there’s the usual. No incentive flights, not only for VIPs etc., but also for staff like flight doctors. Or desk jockeys wanting to keep their licence. LM should develop an F-35D imho.

    Yes but surely they considered that when calculating the final scores. The others sent twinseaters too.
    And it’s not like the Swiss AF is not flying C and D Hornets, or E and F Tigers for that matter.

    You are talking about Gripen C in the last evaluation. Gripen E holds a lot more fuel internally. IIRC about 40% more. Just checked –

    Source: https://www.airforce-technology.com/projects/gripen-e-multirole-fighter-aircraft/

    True. But Gripen E is also heavier, about 8 t vs 7 t. And it has a more powerful engine, about 10 t vs 8.2 t of thrust.
    I estimate this results in an increase of 20% more flying time at full burners. Actual combat radius probably increases more than that because you only use full burners on the way to the target. May or may not be enough to pass the test mission the Swiss AF flew in 2008. But this is a moot point now.

    Thanks for the info.
    Just came across this official source, which confirms the 12 H-1 will replace the Mi-24/35.
    (well I read the google translation… 😉 )

    Obviously fake.

    8 Hueys + 4 Cobras is an awfully low number. Any chance of further orders?
    There’s 17 Hinds alone currently, right?
    Or are the H-1s to replace the Hind fleet only? Hip stays? What about the W-3?

    Nice Rafale Demo this year in switzerland. Enjoy!

    Yeah that was good. Gripen too, excellent, and both well received by the crowd.
    EF not so much. But that was to be expected with the German AF flying the demo rather than a company pilot.

    Dassault also had the best sales department on the ground. And by best I mean the prettiest 😀
    Boeing didn’t seem to have a stand accessible to the general visitor, that or I have not seen it. No demo or mock-up aswell. But sponsoring the VIP-tent – might actually be the smarter move.
    F-35 mock-up was present. Surprisingly compact jet also in real life. But also as fat as expected.

    Got some nice pamphlets from LM/P&W, Dassault and Saab.
    The LM ones seem to be put together in haste, contain some errors.
    Saab quotes the well known cost per flight hour study from Janes. Well, it doesn’t matter now anyway.

    The star of the show was not one of the three current eurocanards, but the Sk 37. :eagerness:

    Finland is not part of NATO…
    That is a Spanish Hornet.

    No its subsonic.
    But it would be a replacement for the subsonic Saab 105, not the EF which stays.

    Fighter variant of M-346 secures launch deal

    Leonardo has secured a launch order for six examples of the M-346FA – the fighter attack variant of its advanced jet trainer – from a major “international customer”.

    Hm, I wonder if it could be Austria?
    The Saab 105OE is in desperate need of replacement, but Austria currently has a technocratic government, which was said to defer any major decisions until after a new elected gov. has been installed.

    Training jet. LO not required.

    Well it is 08-4156, a Block 40 jet from the 94th fighter squadron i.e. a frontline squadron.

    Even better resolution here: http://eng.chinamil.com.cn/view/2019-07/17/content_9560648.htm
    Some excellent pictures I must say.

    We are using F-35 A-A stealth configuration to estimate ferry range, that would be at best four AIM-120 so it is 0.6tons weight which less then 3% of total plane weight (plane+fuel+weapons). Drag impact of four AIM-120 (with pylons) would be lot bigger then 3% of additional weight.

    Well obviously A/A load has less impact. That’s why A/A radius is bigger than A/G radius.
    Drag of 4 missiles is negligible on most fighters.

    F-35 using of afterburner/supersonic flight is quite problematic if you look what we read about B and C version so I really doubt LM presentation at all using them in that presentation. I think what they presented is relaxed combat radius which can be used for ferry range estimate.

    No problems reported about the A model, and B/C performing according to specs.
    We don’t know of course what LM does or does not include in their 760 nm A/A radius. But it surely includes some things that result in a range penalty compared to a ferry profile.
    Either way, we know for certain ferry range is more than 1520 nm / 2815 km.

    Combat range is similar to ferry range for 5gen because they carry weapons internally. 4gens carry them externally so that impact combat range a lot.

    Not really.
    1st, the weight of the weapons reduces range. Weight has probably a bigger impact than drag at subsonic cruising speeds, but that’s my guess.
    2nd, ferry range doesn’t typically include the use of afterburners, maneuvering or flying at suboptimal combat altitude.

    I can think of many instances, F-16 was generally believed to have a better endurance than the heavier twin-engined MiG-29. I’m not sure there was much difference in range between the F-16 and F-15, was there?

    F-16 has much better range than the early MiG-29. No surprise if you look at the numbers – both carry about the same amount of fuel, but the F-16A is only about 7200 kg, the MiG-29A about 11 tons.
    F-16A also easily outranged the F-15.
    Over time, the F-16 gained weight. The MiG-29 on the other hand got increased fuel capacity, closing the gap.
