    F

    -35:

    empty: 12,000 kg
    “laden”: 20,100 kg
    MTOW: 27,200 kg

    Thrust: 178,000 N
    Wing: 42.7 m^2

    The thrust figure is higher (181,120).

    Anyway, why are you so sure that the f 35 will be draggy? It might have a lower aspect ratio than a pure fighter, but don’t forget that it’s a sleek plane, since it doesn’t have any external store. Also, the lower aspect ratio won’t add to much dragg, unless the plane go supersonic (which the F 35 won’t do more frequently than present planes).

    BTW, the F 35 carry more fuel in order to achieve a combat radius of 600 Nmiles on internal fuel (twice the combat radius of the F 16 without external fuel tanks)

    Its kinematics are not good – thrust to weight ratio and wing loading compare poorly to the F-16. The F-16 being designed in the 60s.

    Actually its TWR and wl is better thatn the F 16A–and these were like sportcars, compared with later F 16s.

    As far as I was aware, foreign airforces are never allowed to fly AGAINST the F-22, only with it.

    So, no, I don’t recall the comment.

    A RAAF pilot flew an F 15 in red Flag, IIRC.

    This powers four tail-mounted axial thrusters, and four divert thrusters positioned at 90ΒΊ intervals around the midpoint of the second-stage fuselage.

    I missed the “midpoint of the second -stage fuselage” part πŸ™‚

    No chance of anything other than an ABM role, I suspect. NCADE doesn’t carry a warhead, but relies on achieving a kinetic-energy kill.

    Too bad; I suppose that adding a small warhead could be compensated by enlarging the first stage, so the center of gravity would remain unchanged. IIRC, the PAC 3 is also hit-to-kill but still has an “lethality enhancer” wich is a smaller warhead.

    Since the second stage of the NCADE needs cruciform wings, the AMRAAM rocket motor has been shortened to keep its front end aft of the wings.

    ??
    From the picture, it seems that the second stage doesn’t have any wings.

    100 miles (180 km)? Wow!

    I wonder if this figure will remain the same if the NCADE will be used in A-A. It woud best the Meteor, without the pains of fielding an ramjet missile… Not to mention the IR seeker instead RF seeker.

    I was under the impression that Italy and Turkey already ordered the MESA AWACS…

    Are you sure? I personally don’t consider ECM, AWACS or jamming capabilities of eurofighter nations to be significantly better than Russian ones.

    Actually there are 17 NATO AWACS (registred in Luxemburg ;)), aside the 5 or 6 that UK have; also Italy will receive 4 Wedgetail (AESA-type, like the ones received by Australia).

    OTOH, I agree, if Su 35 will be as good as the Russians say, the EF has little chances.

    $40 bn!!!

    1. US is famous for wasting money for one project developing many types of proto vehicles. Like YF-23.

    2. In US R&D costs manytimes more than that of Russia and India. Because of both labor and raw material price in domestic market.

    3. Russia already developed and pioneered many technologies like advanced weapon systems, super maneuverable FCS, TVC and stealth etc from SU-47, MiG MFI, SU-30 MKI, MIG-35, SU-35.

    4. Russia sold India SU-30 MKI for about $ 40-45 mn a piece which is a dual seater, twin engine long range heavy fighter with PESA radar and TVC. Is it possible for US to sell same type of fighter at that price??

    1. The $40 bn was the price of getting the Raptor from YF 22 up to the operational F22 in Dec. 2005. It has nothing to do with YF 23.
    2. OK, let’s say $20 bn.
    3. is there any trace of stealth in the fighters you mentioned?
    4. Is this the total cost of the program (including logistic, spares, training, service, etc.) price, or just flyaway price?

    I think, with these numbers Boeing would be able to deliver a strike-version of the F-15 at some $75-80mil a piece, but definitely not in an unique customer-oriented configuration (which involves quite large development and integration cost). Anything like that would dangerously approach or cross a $100mil mark.

    The F 15 K total cost per plane is ~ $ 100 mil (total cost for 40 jets is $ 4 bn), including logistic, spares, training, two simulators, service, spare engines, spare radar sets… And remember, compared to the USAF “E” the K has PowerPC-based avionics, upgraded EW suite, the best IRST in service (an improved version nof the AAS 42 first introduced on F 14D) and GE 129 engines. Considering that the plane is new for ROKAF (so the the cost of the logistic tail must be important) I think that $ 100 mil per jet is a good deal.

    That is right but we can just learn the details about Russian and Indian versions after the discussions finish.I think if they spend enough money for this aircraft,it can be very competitive and also can be better than F22.

    They would have to spend ~ $ 40 billion (at the value of $ in the ’80s and ’90s, not at todays value) if they want a better plane…

    x2.

    – They will use afterburners more (leaving a bigger IR signature)

    F 22 wont’ use AB; and BTW, why AB will make fighters more vulnerable in A-A than in A-G ????

    Turn on their radars (and everybody will know where they are)

    Not if they have AESA radars

    These are the first prototype that the US and participants partners will use for testing. The production fighters will cost less.

    During the Vietnam War, American planes were accidentally shooting down other American planes with missiles, because at far distance they can’t see if the target is friend or foe. So in the end, many of the air combats involved just using the plane’s machine guns, because of fear of shooting down friendly aircrafts.

    True for Vietnam, but not for later conflicts. Take a look to the attached graph. While the cannon was mostly used until Vietnam, the short range missles got their peak use during early 80′ in Bekaa valley or Falkland, from Iraq (1991), BVR is the king.

    Romania:
    – the first jet (trainer): YAK 17 UTI; the first fighter jet: YAK 23

    both in 1951

    It has to do with the avionics the larger tactical assets they had and the superiority in numbers

    See this is a F-15A cockpit

    http://www.ausairpower.net/000-F-15A-Cockpit.jpg

    this is a MiG-29A

    http://www.alasrojas.com/Articulos/MIG29/cockpit%20mig29A-2.jpg

    This is a MiG-29M

    http://www.airforce-technology.com/projects/mig29/images/fulcrum2.jpg

    and a more modern F-15 cockpit

    http://atfx.free.fr/coppermine/albums/userpics/10001/thumb_f15_cockpit_01.jpg

    This is the cockpit of the MiG-35

    http://img74.imageshack.us/img74/1429/img5617smtc7.jpg

    With the right avionics and weapons the MiG-29 will keep its aerodynamics and perfromance advantage over any F-15

    As you can see old MiG-29s can fight on a one to one basis, but outnumbered, without AWACs and no R-77s is easy to see why they could not achieve success and this was in part a result of the collapse of the Soviet union and the fact MiG MAPO could not sell more advanced MiG-29Ms in the 1990s, in fact it was until the late 1990s and early 2000 that they satrted selling more advanced versions

    Since when we could evaluate the the performances of a fighter by observing cockpit photos??:p

    You probably supposed that since both F 15 A/C and MiG 29 A have only one CRT, the MiG 29 can fight on a one to one basis with an F 15 :p

    The diference between radar range, radar modes, radar jammer resistance, EW suites, AAMs means nothing to you…

    It is true the R-33 is not active, it is semi active however th Zaslon is a better radar than the AWG-9 and the reason is it can guide four semi active missiles at different targets simultaneously, so indeed i was wrong in the way it works i acknowledge it however it still can be fire simultaneously with other of its kind by the Zaslon.

    Zaslon was better??? It can guide 4 semi-active missiles while the AWG 9 can guide 6 (in practice only 4 were carried) active AIM 54, at a longer range ! The only thing Zaslon can do better is a rapid scan, compared with the MSA of the AWG.
