    he starts out by stating its not supercruise in a technical sense, i.e not level flight,
    and a dive will inevitably be limited in range, before unpleasant stuff happen.

    150 miles dive?, from 40.000 ft to sea level? are you trolling or actually that dumb? ( FYI, if it was a dive, it would be around 3 degree downward) how can such a shallow dive give enough push to cross mach barrier in mil power bellow 10.000 ft?

    .

    i’ll be amused if whomever said f-35 can continue at m1.2 for 150 km didnt add ‘its not supercruise in a technical sense”,
    to cover up the fact that F-35 can take a dive and carry on 150 km at m1.2 before crashing in the ground

    let not spread nonsense here shall we?
    it is 150 miles not 150 km to begin with, and how shallow the dive have to be for F-35 to be able to go 150 miles? and exactly such shallow dive add enough thrust? and talking about diving, what magical reason do you think a super extremely shallow dive can make F-35 fly at mach 1.2 below 10000 ft in mil power? ( since by your words, it will crash into ground after 150 miles)

    it won’t see at longer distances unless connected to high mag optics..

    So doesnt matter how much infrared radiation the target give out ( different in temperature ) , all targets will be detect at same range ? , did you just pull that BS nonsense from your …????

    BFM or cruise, all energy bleed happens due to drag.. Nothing else..

    The different is in BFM , you are not at 0 AoA , your flap and stabilizer will also moving alot , that not to metioned the fact that in the test you was talking about , the F-35 go max elevated AoA

    single good reason not to optimize a design for supercruise when know-how, technology and funds are available..

    supercruise = low bypass engine = higher IR signature + shorter range

    The techniques described in your link are pretty primitive, sorry to say that.. What exactly are we dealing with here? “advanced cooling system”,

    some IR reduction techniques are explained in simple terms here :
    RCS/IR reduction measures

    And hum no I don’t think a fighter necessarily spends so much time in supersonic huh. But in some case when it is sent to intercept enemy planes yes it does and in that case the range would be a lot less obviously.

    it no doubt that in reality, fighter actual combat radius is alot shorter than intended because pilot will need to keep reserved fuel just in case things go south , they may be attacked on the way to target, the combat time may be longer than expected.. etc
    but ask yourself, which fighters will be more likely to be intercept and have to use maneuver to survive? the stealthly one? or the one with massive RCS from 3 EFT? ( and not to mention the fact that EFT reduce agility too)

    The test was very very selective, it uses the most favourable scenario tailored to the F-35, if you read where the JSF came in second it doesn’t mention what to… Just take a guess, or where the opposition have 2 extra air to air WVR missiles.. Apples to Apples Pfffft.

    F-35 dont have 6 internal AAM until block 4/5, and it unlikely that 2 aam will affect range significantly

    Its been worked out with as the combat radius with only 1 min of combat where the JSF was able to successfully disengage(LOL)

    they simply use standard profile for all competitors for the purpose of comparing, they did similar things in Brazil competition with the Raf, Gripen and F-18E

    , at the cruise height which the JSF was designed to fly (Typhoon best cruise altitude is much higher and the more combat time it sees the worse for the F-35 results)

    It depend on what you defined “best”, most optimum cruise altitude for turbofan engine aircraft are relatively similar, while the air at higher altitude are thinner and could lead to lower fuel consumption, you need more lift which either mean higher AoA or faster speed, both can increase fuel consumption. Moreover, it much easier for IR sensor to detect a fighter fly high and fast, and aircraft maneuver at high altitude are very poor due to thinner air (even in case of F-22 and Typhoon) so that could be a really bad thing if you get attacked.
    it not just for fun that most military mission profile are between 25-35k feet instead of 60-65k ft

    .

    The F-35 is an aircraft where external fuel carriage isn’t a priority? hmmm thats ok if someone has dozens of spare tankers available to ferry them to the areas of conflict, strange that ferry ability is now not important!

    It also leaves your refueling aircraft very vulnerable to counter air attack, given your F-35 are obviously optimized for 1 min of combat the enemy will have to be pretty permissive to let you get away with trailing tankers behind you in case it goes on for 10 mins. Or are you only planning to fight enemy’s exactly 760Nm away? obviously the Israelis think the situation is far from ideal, that’s why they are looking into EFT’s and CFT’s or are they being silly developing unnecessary capability?

    you left out the fact that others aircraft like F-18, F-16, EF-2000, gripen.. etc need 3 external fuel tank just to achieve similar range and similar combat time. While the tankers for F-35 may be vulnerable to counter attack, for the competitors case, even they, themselves are vulnerable to counter attack since they need to carry 3 EFT.

    For example:- The Typhoon can go ~800nm with a 1 min combat at the end with 3 tanks, the 750nm figure quoted by Eurofighter is for a different profile and an additional 10 mins of combatloiter, now that’s not the profile the JSF is using.

    no, all aircraft in the comparison use the same mission profile, and iam quite sure there is no official source that state that EF-2000 have combat radius of 750 nm with 10 minutes of combat. (it important to know that combat here mean using after burner, loiter mean you reduce you speed significantly to have more time on station )

    , but 10 mins of combat in a F-35 isn’t going to end well for the fat slow kid, especially against a faster, higher flying foe that has more missiles.

    it depends, in this case, the fast and high flying foe is blind, the kid isnt

    Range of flight: F-35A 1,850 km. EF-2000 – 2600 km (without tanks), max. range – 3700 km.

    If on the F-35 were two tanks (installation is not planned), the distance will increase to 2222 km

    Is there any source or you just made up that number?

    So now you pull out the crystal ball so that you can read what I “clearly think”… Well, I think that you don’t think too clearly or is that just immaturity.

    what else do you mean by the statement then ? , I think it quite immature to say one thing then dont dare to admit it .
    QUOTE=xman;2313812]
    Guess Boeing had incentives from US government to participate, in order of giving some legitimacy to a “competition-selection” process lacking competitors. Must admit that their participation seemed to not have been tuned for success. They pathetically aired a commercial, as an example, on some obscure local FM rock station. One can only wonder, what were they thinking and who were they trying to reach?. So all in all it did not seem very serious to me. Hence I guess they are now pretty upset ,from having been abused into participating as some kind of justification by their government and getting hammered on top of it in the end.[/QUOTE]
    So by your logic ,LM is USA favorite manufactured ? USA loved LM so much that they made others US manufactured joined competition just so that LM success look more legit ? ,
    And you think that Boeing some how know they will lose so they only advertisied on local Rock station , but in the end still mad when they lose ???? what kind of logic is that ??
    And can you prove evidence for an of that?

    Where does it say that the F-35 was/is a pure fighter except in your straw man argument? :rolleyes:

    i was referring to thus argument of your

    We all agree that building fighter jets is hard stuff, but no-one forced LM to turn an affordable bomb truck into the most sophisticated fighter program ever

    You clearly think that some how F-35 is the bomb truck that was forced to be a fighters and fighters should be designed seperated.
    That simply stupid, No one can afford to operate pure fighters anymore , all fighter nowadays (not just F-35) are multi role

    Don’t respond to him, there is no treatment for whatever it is he has got.

    Yeah , i dont know why i even bothered

    bomb truck into the most sophisticated fighter program ever. .

    F-35 is a multi role fighter just like every single fighter flying today , apart from internet fan boy not many people want a pure fighter

    its complete new hardware. the pods are getting bigger as they become newer.

    hardware of internal EW can be upgraded too

    show me example of upgrade.

    just google various upgrade of internal ECM for F-15 , F-16 , F-18E

    need to be dealt with high speed Iskander or Brahmos land attack version. not with slow moving subsonic fighter jets.

    fighter jet can move supersonic too

    Stealth planes are overweight,

    compare to what ? , su-34 ? not at all

    draggier

    same as above

    smaller internal fuel capacity

    F-35 carry ways more fuel than F-16 , F-18 ,AV-8B , Gripen, EF-2000 and Typhoon

    not flexible to upgrade.

    It depend on what you want to upgrade

    the space inside in Su-34 simply not enough to deal with diverse threats that are in Syria from Turkish AWACS to ground based radars of nato that need counter measure develop in real time.

    data base of internal EW can be updated in real time too

    only the external pods that can be upgraded and shipped in the transport planes directly from manufacture to the field.

    Internal ECM can be upgraded too

    The function of Su-34 is to use its radar to maximum capacity to see what happening on the ground at extended distance and than strike with Iskander.

    Su-34 cannot carry Iskander

    The function of stealth aircraft is not to use its radar at all. so it very less useful.

    Nonsense

    Su-34 with giant hump pack still need big pods on on wingtip and big tail almost the size of F-22 nose.

    And Su-34 have massive RCS compared to F-22 , if you have higher RCS , you need more powerful jamming to cover your ass , it as simple as that

    So the F-35 has max survivability in DCA.
    It is as good or better than the F-22.
    Who believes that?

    F-22 isnot in Denmar evaluation , and VLO attribute of F-35 should give it much higher survivability compared to others contestant in the competition

    In what way it can have max survivability in CAS?
    By staying at 5,000 meters altitude?
    Looks like BS data to confirm a decision made for political reasons.

    Unless you fly an A-10 , you not gonna fly at tree top level , B-1 ,F16 , Rafale do CAS from high altitude all the time
