    I believe that BVR, one on one, the Raptor is top notch as of today.
    In an open sky, no AWACs, no ground-based detection, it should rule.
    The Rafale may be the better equiped plane operational to contend
    but it will have to wait for AESA RBE2 and Meteor to play seriously.

    There are two things that complete this view. First the Raptor has its
    own problems accounting for the early production end. Second, the
    Rafale can do it all. My prefered bit from ATLC was the 2 MICAs AND
    three AASMs delivered in one pass. Much more useful!

    Good day jackjack and all.

    If the Raptor has access to AWACs and other third party info, it’s advantages will only increase, as it’s optimized for NCW.

    The F 22 can supercruise. It does not do it duroing the entire mission. According to Air Force Association (semi-oficial) data, the F 22 has a combad radius of 400 Nmiles. Within those, only 100 Nmiles are SC. Also, it can fly 500 nmiles including 50 Nmiles SC, or ~ 600 Nmiles in subsonic. So, the SC will cut the flying time in half.

    Actually those numbers are on the VERY conservative side. The F-22 can supercruise for over 30 minutes, giving it a supercruise range more along the lines of 500-600+nm, not to mention the subsonic legs.

    Oh come on..!:mad:

    I suggesting you folks should pick up a few books on Aviation history.
    Reading Aviation books like F-15 engaged, those F-15 did economical subsonic speed while loitering Iraqi airspace, and when upon unknown contact, they would hit A/B and on many ocation drop their DT in order to reach the enemy(get fire solution).
    And on some ocation they didn’t reach the enemy in time, so do anyone think ‘supercruise’ speed would be the right thing to do here?
    Now if it where the F-22 on patrol, it would too go economical subsonic, and then hit A/B trying to reach those enemy contacts.
    It is wery likely the F-22A will to this on future mission around the world too.
    So for the trillion time.. all this supercruise speed is LM talking out of their @ss..
    It is a nice capability to have, but will not be used very often.

    This is a typical every day mission for F-22A who operates out from Alaska.
    Do you really think the F-22 do supercruise in any duration of this mission?
    Its carrying those DT for a very good reason, to stand a chance of identify/intercept/shaddow bombers like Tu-95/160..
    It will be the same with the F-35, it will have to carry DT in a numbers of missions, so who’s talking giberish here..LM:rolleyes:

    Dynamo is very much right here.

    It wouldn’t make sense to supercruise if you’re shadowing a target that’s only travelling at M.85. They may very well supercruise in the initial scramble until they reach the target, and then pace them though. In wartime if they were trying to intercept as far from base as possible, before the bombers had time to launch their cruise missiles, I guarantee you the Raptors would be hauling butt to get there though.

    The 0.3-0.4 m2 probably refers to the “bare” (naked) fuselage without the RAM

    Why would they give that figure, rather than what they anticipate to reflect a production model? Why wouldn’t they mention that’s what they were saying, if that is indeed what they did?

    Most of that will and the Russians have a very practical approach to that.

    I don’t doubt they will work. The question remains as to what their capabilities turn out to be.

    considering these “performance claims”, I guess we’ll still be here arguing for years.. until some F-35’s finally come to their units and (some time later again) they start facing other aircraft.. then we’ll have a clearer picture of what they can or can’t do.

    thing is, even LM’s aim was, they admitted, to match F-16’s performance, not get better.. and for a strike aircraft (which it is, even if some politicians/airforces believe they buy an “all rounder” ) it’s not bad.

    Now, believing it will outperform fighters built with agility in mind, well, sorry, I don’t buy it… it has a powerful engine, but it’s also very heavy… put that engine in an f-16 and you’ll get fabulous performance. put it in a 30000lbs aircraft and you get a good flying brick, not unlike the f-105 or the F-4 at its time. Good striker but not a dogfighter

    The F-35A is under 27,000lb FWIW, and produces ~dry thrust as an F-16C has in full A/B.

    At terminal maneuvering range?

    Who you trying to kid?

    If a fighter size radar with considerably more power, antenna size, etc… has problems spotting a stealthy target, until very near the target, what do you suppose the maximum detection range is for a missile with an antenna of 7″ or less in diameter. It’ll likely be at terminal range by the time it can detect a VLO target. The VLO target will know about the inbound missile well before it’s detected, giving it greater opportunities to evade/employ countermeasures, than a more conventional aircraft.

    It is known a development freeze of the F-35 does not match the F-16 in sustained turn rate.

    In fact, it cannot match the F-4E.

    Unsurprisingly, Lockheed lie and people believe them.

    An F-16 will go from 0.8 to 1.2 in under 30 seconds at 30,000ft!

    So the USAF is lying for LM too then eh?

    I know one doesn’t necessarily imply the other, it’s just I would have considered the challenge of creating a stealth aircraft, modern avionics, powerplants, AESA etc. to be much more challenging and costly than a frame less canopy.

    Again, I guess it’s a question of priorities.

    Materially, how difficult is it to meet the challenges of resilience to bird strikes, prolonged supersonic flight etc, with a one piece canopy?

    Well they still don’t have the ultimate powerplant ready, which will be another 10-12yrs according to Russian sources. They’re using interim motors right now, and we’ll have to see how the other systems work too.

    No. There are not. Typically before finding yourself in the situation of having to dodge a missile you will have been maneuvering. If your aircraft bleeds off more energy, then you are in a more vulnerable energy state when it comes to trying to avoid the missile.

    However if you are stealthy, you have a much greater chance of breaking a missile lock.

    Care to provide the statements?

    Here’s one from a LM press release-

    http://www.f-16.net/news_article3063.html

    The F-35 has the most powerful engine ever installed in a fighter, with thrust equivalent to both engines today in Eurofighter or F/A-18 aircraft. The conventional version of the F-35 has 9g capability and matches the turn rates of the F-16 and F/A-18. More importantly, in a combat load, with all fuel, targeting sensor pods and weapons carried internally, the F-35’s aerodynamic performance far exceeds all legacy aircraft equipped with a similar capability.

    http://www.airforce-magazine.com/MagazineArchive/Pages/2009/July%202009/0709Fighter.aspx

    Internal Vs. External

    The F-35 was designed with an entire air campaign in mind. For “first day of the war” operations when stealth is of supreme importance, the F-35 can carry two 2,000-pound bombs (two 1,000-pound bombs for the F-35B) and two radar guided dogfight missiles internally. Critics of the F-35 have complained that this loadout is far too light for sustained combat. However, in stealth configuration, all F-35 fuel is internal, as are all sensor and targeting systems. On legacy aircraft such as the F-16, fuel, weapons, targeting pods, etc., are carried externally and their weight and drag severely hamper performance. With a full internal load of fuel and weapons, the F-35 is as agile as a “clean” F-16 carrying no weapons. In other words, in stealth mode, the F-35 gives up nothing in range or weaponry, but adds considerable ability to penetrate enemy air defenses.

    Now, tell me about this cookie jar. 😎

    On the one hand, Sukhoi can create an aircraft that can compete with the F-22, but on the other – they can’t create a frameless canopy? :confused:

    If the RCS is only .3m^2, that’s not even as good as they’ve achieved with a Mig-21, much less as good as the Raptor’s.

    I assume there is a real challenge involved but, if one has the supercomputer capability and material technology to assure stealth across various wavelengths, one assumes it’s perfectly possible to come up with a formula to create a suitable frameless canopy?

    A question of priorities I guess.

    Not necessarily. Merely having access to supercomputers doesn’t mean one has the know how to do everything. The Russians are still buying foreign UAVs due to the lack of expertise to build locally, and meet the standards that the RuAF expects.

    It is about a working network of a capable adversary. When Serbia was more like a “training gound” in a limited conflict something like North Korea with some foreign support can be become a real challenge fot the F-35s. 😉

    Serbia managed to shoot down an F-16 and an F-117(which had flown countless missions unscathed both there and in Iraq). The F-35 is a far more capable aircraft, and will be available in far greater numbers, with a far wider variety of weapons. I won’t argue that N. Korea, China, etc… would be a more challenging air defense to penetrate than Serbia, but having a large number of stealthy attackers linked in an NCW manner isn’t anything to sneeze at.

    What about the wavelength of the radar your facing?

    Lengthen that radar wave, and pretty shortly you’ll find those decibels rising, and rising damn sharply!

    The types of radars which you’re speaking of are generally fixed sites, or are not highly mobile, which means they’d be very high priority targets for either kinetic strikes or stand off jamming. The fight is at the systems level, not the individual platforms.

    I strongly suggest you reconsider that. Particularly for large long range AAMs.

    It is an absolute myth that a modern 40g missile cannot be out-turned.

    60g missiles in a healty kinetic energy state… different story… although if the stories of some fighters being able to take 12 or 13 g if needs be are true… then even that is open to question.

    You’re missing my point- from an agility standpoint, there are negligible differences in survivability in modern fighters. In otherwords, if we take ECM/countermeasures out of the question, and have equally capable pilots flying an F-16, M2000, Typhoon, Gripen, Flanker, etc…there’s not going to be a considerable amount of difference in survivability(if the conditions are the same with regard to the incoming missile.) So……to say that an F-35 is more vulnerable to being shot down due to it’s “lack of agility” is simply ridiculous.

    Better performance than the F-16? In what measurable parameters?

    Sustained turn performance? Nope.
    Pitch response? Nope.
    Pitch rate? Nope.
    Roll response? Nope.
    Roll rate? Nope.

    I wonder if you’d care to provide the numbers for comparison. The statements I’ve seen from the USAF regarding the F-35A are that a combat loaded F-35(stealth configuration w/ 5500lbs of weapons and full fuel load), outperforms a clean F-16C. If you’ve got the numbers to refute their claim, I’ll be happy to be educated.

    Having a larger controllable ultimate AoA means virtually nothing as you have no energy left to even try and avoid a missile after stalling for a few seconds.

    The point isn’t to bleed off airspeed. It to enhance the carefree handling envelope.

    The comparison with the F-105 is quite obvious. An attack aircraft which had a secondary consideration for A2A combat. The heavy use of electronics was required to compensate for a poor airframe.

    You may want to occasionally refer to other sources than the APA.

    None of which are an inherent capability of the airframe. Exact same as the F/A-18. Use brilliant, mind-bogglingly good electronics to hide an absolute sh*tbox of an airframe.

    The airframe in question will allow that F-35 a far higher degree of survivability against modern SAMs and fighters, than those with higher RCS, which will need raw performance, to have any chance of getting home.

    I don’t think that missile development is quite so clear-cut nowadays.

    A lot of development is now done using computer models and other simulations, including hardware-in-the loop (HWIL) testing of critical subsystems. On an expensive programme such as Meteor, flight testing comes at a relatively late stage and after a small number of shots uses what is virtually production hardware. So FMRAAM and ERAAM would have been more than just paper projects.

    I’m not sure how far the Russians have gone along that route, but I know that Mercurius Cantabrigiensis has been briefed by the Russians on some of their air-to-air HWIL work. But one of our moderators p****d the old boy off by deleting one of his postings, so he no longer posts here. So I’ll try to ‘pick up the slack’ occasionally on missile subjects. Up till now I’ve made only a handful of postings.

    He may still be ‘lurking’ without posting as do a number of other aerospace professionals who just don’t want to get into the sort of squabbling that so often takes place here. A wander around the listing of forum members sometimes reveals interesting (indiscreet might be a better word) usernames that rarely if ever appear on postings!

    The point I was making to him though was that if anything, they had computer models of this variant of the R-77. I haven’t seen anything that demonstrates a working prototype that had reached flight testing stage, much less being anywhere near being fielded.
