    The D as well as the C7 is booster-only. Which means that in less than 10 s. there will be no hot gases exhaust for the IRST to see.

    Eeerrrr, like the very important “Made in the USA” requirement…

    The agreement was ~ SRAAM by Europe, LRAAM by the USA, but the US decided against that.

    Not quite. Because, if selected, the ASRAAM would have been manufactured in the US. It just wasn’t good enough…:p

    So Europe went with Meteor because the US LRAAM “didn’t meet European requirements.

    i.e. ” Honour your agreements” 😉

    Cheers

    😮 Really? I must have been fooled… I thougth that the RAF Tornadoes and EFs have AMRAAMS; As well as the German F 4s and EFs. Not to mention the midgets (Gripens). I also believed that until the wunder Meteor will appear, the AMRAAM is still the most sophisticated missile in W. Europe.

    However, i don’t fly the things, and i am only offering my opinion based on what i have read. The AIM9X was a cop out that was rapidly developed once the US fell out of the ASRAAM though. It doesn’t mean you don’t have something better in development but its not as capable as ASRAAM (and ASRAAM isn’t even the best dogfighting missile out there).

    ASRAAM was evaluated by USAF/USN and guess what… it failed to met the requirements !

    My understanding would be that assuming the F35 survived the initial meteor launch then it would be in serious trouble with the ASRAAM before it could launch the upgraded 1950s infrared missile you talk about…

    Your beloved ASRAAM has the same IR seeker as “the upgraded 1950s infrared missile” you despise so much. Both seekers are made by Raytheon.

    Well Scooter,

    I would suggest that F18 and F16 engagements against Typhoon would be slightly less exciting for the Teen series fighters.

    That’ why the F 35 is better than F 16/18. It is comparable with a clean F 16 in terms of acceleration and a clean F 18 in term of AoA capabilties…

    I think air superiority is fine for the A2A F35, but there is no guarantee of superiority over european designs.

    For argument sake, let’s admit that the Eurocanards has a small edge at high speed over F 35.

    So?

    What makes you think that they will be comparable with F 35stealth/sensors?

    You mean where most combat occurred 30-60 years ago i take it ?
    rest assured no modern fighter, F-22 included, will default to subsonic.

    While supersonically the F-35 is limited to a seemingly unimpressive Mach 1.6 in level flight, Davis explains that the JSF is optimized for exceptional subsonic to supersonic acceleration. Transonic acceleration is much more relevant to a fighter pilot than the absolute max speed of the jet, Davis said. Davis( Major General Charles Davis, USAF, the Program Executive Officer of the JSF program), who was previously the program manager for the F-15 Eagle, explains that while the Eagle is a Mach 2 class fighter, it has rarely exceed the threshold of Mach 1.2 to Mach 1.3 during it’s entire 30 year life span. Additionally, the time the aircraft has spent in the supersonic flight regime can be measured in minutes rather than hours- most of the supersonic flights were in fact during specialized flights such as Functional Check Flights (FCF). “I don’t see how that gets you an advantage” Davis said, referring to the Mach 2+ capability. Beesley said that in terms of supersonic flight that the F-35 is still more than competitive with existing designs

    And he was talking about the F 15, a fighter that have seen more combat than all the modern fighters…

    The bloody thing is that now they need to make money with a fighter that has none of the described virtues – is neither stealthy, nor fast. So they have to either disprove all the claims they have made before or make the F-35 look a bit better than it is by highlighting the few good things it has and keeping shut about everything else (especially speed, aerobatic capabilities and RCS).

    Who told you that the F 35 is not “stealthy” ? Or that it hasn’t “aerobatic capabilities” ?

    You are talking 10 yrs out though. Much can happen between now and then surprise wise. I’m sure you would have been blown away in disbelief 10 yrs ago, if someone contemplated out loud the current day situation and outlook today. It would be foolish to underestimate the capabilities of unprecedented, fast paced technological and asymmetrical advances going forward.

    Yes, these are very uncertain times and if you don’t believe it, I can refer to you the Quadrenial review as an interesting synopsis (albeit one year old data already). Better to be flexible and not tied down to any one budget killing MIC bomb truck in particular.

    If anything, it will be US based UCAV which will threaten the F-35, procurement and doctrine wise by 2020.

    We’ll have to unfortunately wait a couple years still to see if and where the policymakers regain control of a prudent Tac-air recapitalization strat.

    -US UCAV programs are a few years ahead;
    -no other nation has an operational UAV comparable with Predator/Reaper that can fire A-G PGM; nor comparable with, let’s say, a Global Hawk;
    -no other coutry has available know-how in stealth comparable with US

    Dear sir,

    Which F-35 are we discussing? the A model or the C?

    A; C has a longer radius

    How will the F-35 deal with a large number of UCAVs having RCS significantly lower than itself?

    The main threat to F-35 will not be from the past (F-16) or the present (Typhoon) but from the future (networked stealth UCAVs).

    Considering that US has the most advanced programs of stealth UCAV, who would be this threat you are talking about?

    Well the data available suggest that the Typhoon has an even greater range despite 3 tanks, which will still keep the aircraft’s fuel load (internal+external) below what the F-35 carries internall

    NOT quite:

    Discussing maximum mission radius, Mazanowski presented an air-to-air mission profile in which all the aircraft took off with a weapon load, remained at high altitude and returned after about a minute of combat. All but the F-35 and Su-30MKI were carrying three external fuel tanks.

    Under this scenario, the Rafale had a maximum mission radius of 896 n miles, the F/A-18 816 n miles, the F-35 751 n miles, the Eurofighter 747 n miles, the Su-30MKI 728 n miles and the Gripen 502 n miles.

    In the context of A2A fencing, a realistic appreciation of AAM’s limitation is essential.

    The DRDO said Astra will be able to be launched from different altitudes but those alterations would affect the range.
    It will cover nearly 70 miles when launched from an altitude of just more than 9 miles
    but only 27 miles when fired from an altitude of 5 miles.

    At sea level the range is expected to be 13 miles.
    Active homing range will be nearly 16 miles.

    A longer range version, the Astra Mark 2, will have a 93-mile head on range with a tail chase range of 21 miles.
    http://www.upiasia.com/Business_News/Security-Industry/2010/07/15/Indias-Astra-tested-for-night-operations/UPI-69881279199751/
    70 miles =60nm=110km
    9 miles=14 km
    5 miles =8km
    27 miles=23nm=43km
    13 miles=11 nm=20km
    16 miles=14nm=26km
    93 miles=81nm=150km
    21 miles=18nm=34km

    As we can see, an impressive 93 miles=81nm=150km range on a head on shrinks to a mere quarter on a tail chase, (21 miles=18nm=34km) which would be the first thing the shot at fighter would do, equipped with MLD/MAWS, and reasonable high alt agility.
    If he then proceed to take a dive, we can shave off half of that quarter,
    for an effective range of that 150 km missile in practical term is
    ~10 miles=9nm=17km, = well within visual range.

    Except that the situation will be different for an AA missile, because the shoooter is moving towards the target, adding its speed to the missile. Generally, for an AA missile, the distance in chase is reduced by half compared with head-on.

    Why?

    Because 1) AA was heavier and 2) because AF will be cleared to full flight enveloppe, which wasn’t the case with AA.

    So far the F-35 hasn’t demonstrated much at all! Turning as good at high subsonic speeds is not a great deal at all. What’s the highest AoA, speed, altitude, g-load etc. the F-35 has achieved yet?

    55 deg AoA trimmed flight; >50 deg/s pitch rate; 1.67 M; 50.000 fts; 9G;

    Caution: the plane that achieved those was the AA; the present AF performs better.

    Do you really believe that Underwing Pylons, Missiles, and External Fuel Tanks have no effect of Performance.LOL:rolleyes:

    As a matter of fact Jon Beesley has stated that even a single AMRAAM’s has a big impact. It’s also worth noting that a single external fuel tank. Requires half the fuel in the tank just to over come the weight and drag!

    It’s not me, but Obligatory that was convinced that external stores do not degrade the aerodynamic qualities.
