    As a 5th Fighter definition (used in that context) it is accepted and used by the developers of —>
    – F-22A
    – EF typhoon
    – SAAB Gripen
    – Su-35BM
    – Pakfa
    Maybe i missed a few .

    You did lost sth important.

    Maybe that should be accepted that is used by You ???

    Not even you

    somebody come here state sth sounds like a judge

    This definition of supercruise used by the F-22 first (no doubt) but it has been widely used by many projects of 4.5 or 5th generation outside the US , the Russians have used it ,

    Who told you Russian has accepted it? The Su-50 hasn’t flown, they even claimed MiG-31 was the first supercruise interceptor.

    Again i emphasize that this is a BROCHURE term only , its not a term of PHYSICS or SCEINCE , you may call it whatever you like . I know you are pissed because MAYBE (a big maybe) it was used by someone in the US in the ATF program and maybe that Pisses you off (i dont know) but get over it as this is only marketing and brochure discription of the ability to go fast for long periods and in the case of 5th gen figther it is without AB beacuse AB compromise on another feature of 5th gen fighters . Its pretty simple so dont take it personally !!!

    Now that’s it! WHO TOOK IT PERSONALLY????
    “Its not a term of physics or science”, but somebody calls it define? If somebody have any little basic knowledge of science, he must know that define formally is belong to category of science. You can call sth personally, but you have no right to define until what you called was proved or it could be identified and discriminated from others.

    This isnt my definition , it is the most widely accepted one —->

    A supercruising aircraft is able to maintain supersonic speeds in level flight without the use of afterburners.

    http://en.wikipedia.org/wiki/Supercruise

    Anyways i dont see much in a term anyways !!

    it is the most widely accepted one

    What does this mean? widely accepted or was widely accepted by USA?

    The WIKI is a web any one can edit it, the definition also was made in USA. do you mean that a definition should be accepted because it made in USA?

    ……Technically SUPERCRUISE as defined in the context of 5th Fighter is the Ability to go supersonic (usually well over supersonic) Without the Use of Afterburners . So yes if your Flying Dish can go well over supersonic for long periods without AB use then it could supercruise . Aircrafts like the Mig-25 , Mig-31 have been flying supersonic for prelonged periods for years but with AB and although it is not TECHNICALLY SUPERCRUISE (as per modern 5th gen use of the word) but the effect is pretty much the same.

    Does your define cover what engine should be used? Or just making supersonic for longer enough?

    What is your source on that? AvWeek and others give the YF-22’s internal fuel as something like 23,000-25,000 lbs.

    much closer to this was a figure for YF-22
    AND HERE IS F/A-22

    Till here, this thread goes, gives me all thoughts in which most key point is, if a flying dish can do supersonic over 1 hour or 2 hours sustained and persistently, may we call it supercruise?

    I did search my memory, no SFC of the F-119 revealed, according to the combat radius and internal fuel F-22 carried, I would say, the SFC of the F119 PROBABLY higher than F110.

    The graph surprises me. Do you know the configuration?
    I guess that it is F-15C with missiles and probably even (supersonic) tanks. Please explain!

    The advantage F-22 taken was even not so great since F-15E was refitted new engine which more powerful than original one.

    That may indeed be the case but arguing about the F-22s VLO is a moot case. Cold war specs were unrealistic and any drop in overall signature is not a big issue as its frontal RCS is the most important aspect and where it excells the most. We have no idea of the extent of the changes – to the Raptors all aspect stealth. But they seem to be relatively minor in my opinion as its performing extremely well in exercises. So whatever tradeoffs were made they were aimed at producing the best product.
    ……

    The Cold war has never been fired to be a Hot war, so any experiences taken from cold war are not appropriate to judge weather a design of a/c survivable or not. Remember, the F-22 is a Raptor only being an area that controlled by US completely, being somewhere else, it will be a Rabbit. We have already seen when USAF beet a country small like Iraq, the a/c sent by USAF resemble a cat which is catching rats. BUT, when Taiwan ask him for protect from Beijing, it looks like a rat which peeping at a cat.:p:diablo:

    Don’t forget a country like Russ or Chine, are large country not only for population but also for their domain. The enemy won’t just come from frontal forward more likely comes from every where.

    Define short ? What is short time ? How is it measured? Against requirment for Air defence or what you want it to do “around the world @ mach 1.72?”
    According to AW&ST, June 12, 2006 ——>
    For the anti-cruise missile mission, F-22A can cruise 41 minutes with the speed of around 1.5 Mach, while the traditional fighters like F-15 and F-16 can just cruise 7 minutes with that speed.

    Is the afterburner adjustable please considering.

    then,The EC version of Su-24 will be heavier than others, my stand is consistant always.

    For numbers really , the F-22 is capped (production) and even F-15’s falling out of the sky couldnt get the congress to increase that cap , mainly because they see it as an expensive big ticket item and secondly because the F-35 which is also a LMA product , happens to dwarf the F-22 interms of economy (how much money it will generate back into the economy) and Jobs aswell as foreign sales for Lockheed which come what may will always back away from the f-22 if a direct choice is to be made.

    An upgraded F-15 C is NOT OUTDATED by any standard , give it some modification and it can still face any threat for the next 10 years or so , and with reducing no. of raptors (183 instead of 300+) the USAF has no other choice but to keep F-15C’s for longer.

    English is a sort of very interesting language.
    On one hand, “not outdated by any standard“, does which mean standard of stealth INCLUDED?, on the other hand, “the USAF has no choice but to keep F-15 for longer”, if not outdated, what choice needed for? COMPLETELY INCOHERENT:diablo:

    Does incorporating stealth automatically confer a lower degree of aerodynamic efficiency than the F-15? No.

    This depends on what is the stealth as you said due to?

    Why is everybody always pissed when I say something that might made the Raptor look not like the 120% Über-Fighter of the next 5 centuries?

    I’ve said that data Sukhoj web given are very WRONG.

    I must knew that EW of electric combat a/c generally bigger than other variant version.

    F-111 and Su-24 have similar EW EXCEPT EF-111.

    Why to use these two airplanes? well because very likely both aircraft have similar fuel capacity see the EF-111 will carry at least 15000kg of fuel and the Su-24 very likely will carry around 16000kg of fuel according to Sukhoi or around 14500kg according to the Ukranian air force and Yefim Gordon, since the EF-111 can carry too two external fuel tanks

    Very Well, It seems that we have a consensus on the major part.
    But this paragraph I quoted from you, which I have a little different view.

    1) EF-111 will never carry fuel more than or same as any other vertion of the F-111 serious. so the 15000kg is a suspicious data since the fuel loaed in other F-111 version slightly less than this number.

    2) The data lost unit liter or kg may obscure the editor who wrote the article concerning the internal fuel capacity Su-24 carried. Around 16000 or 17000 must be liter with two 3000 liter EFTs, whereas the data around 13000 or 14000 seem to be kg as unite. If you reduce two EFTs weight from 14000kg, the result is quite closer to the weight of internal fuel JAWA adopted. Certainly, no matter 16000, 17000, or 13000, 14500, both of them are approximate number around the actual data.
