    It is lack of investment in Soviet manufacturing and IT that led to such end products. Nothing do to with design of aircraft. The same MIG-35 can carry 50% more fuel of MIG-29 but still weigh the same with 6500kg weopon load and Mach 2.25 speed which F-16 cannot reach.

    A Mig 35 won’t see M2.25 in combat either.

    The BS info and then sarcasm flies right past you . . .

    I wasn’t quoting you, but thanks for the tip.:cool:

    Two Russian Tupolev-162 strategic bombers — each capable of carrying 12 cruise missiles armed with single 200-megaton nuclear warheads — carried out exercises in Venezuela last month.

    :eek::rolleyes:

    I’m gonna have to raise the BS flag on that one. Exactly how large are these cruise missiles?

    There is no evidence to support your F-35 RCS claims here either LOL!

    The best open source I’ve seen is in the .001 range or better. Without access to the classified info on the Russian equipment, and the F-35’s true RCS, we’re just pissing in the wind.:p

    It’s a bit disengenous to be a fan boy over Russian equipment(without access to the true capabilities), yet have the nerve to try to call out anyone else over another piece of equipment(that no one here knows the true capabilities of- or that can say).

    Export product shows progress of Industry. since US is not allowing export of F-22 but Russia will create Twin engine, long range, supercruise, Super manevorable, multirole export 5th generation fighter. It shows alot confidence. Similar is the case of Su-35. 400KM range radar for export. Russian officials always remind that export products performance is down graded. Iskaner-M has different range, stealth characteristics, end game manevourability and seeker with real time communication from satellites and UAVs.
    I only mentioned that under poject 810 Vympel is creating longer range followup of R-37M. Simlar is project 610. etc. Russia always retains combat edge in sensore, weopons, EW etc. Kh-31PM and Kh-31PMK ring the bell.

    I don’t doubt that certain performance aspects are downgraded, but I find it hard to believe that every single piece of equipment, and all of their components are all downgraded. Or that by reverse logic that one can assume that there are automatically huge performance increases of all pieces of equipment that are for Russian use. In other words, perhaps a sensitive system is detuned 5, 10, 20 percent, but I seriously doubt that the Russian equipment is 100 percent(or more) better in terms of kinematics, detection, etc.. This isn’t the Cold War and Warsaw Pact/Soviet client states countries. This is-if you’ve got money, we’ve got weapons time.

    And why do u suppose that these are for Ruaf?

    Thise article is from 2005/06. R-77 is getting increase in range of 4 times. Similar is 4 times increase of R-37 class missile. These seekers are for countries for down graded radars in there fighters so missile has to do things by itself upto 70km. Export missiles cannot interept hypersonic and stealth targets but Ruaf missile does. Similar is the difference between Iskander-M and Iskander-E.

    Why do you post articles, and then when they don’t support your claims resort to “well these are for export, not RuAF?” Did those articles say that those were export specs, as I didn’t see that mentioned? Are you telling me that the R77/37s of 2008 have 400 percent more range than those from 2006? So is the R-37 up to 2400km in range now?:eek::D:rolleyes:

    This things are for export thats why they showed it at Paris show. For Ruaf missiles they wont be discussing.

    I see.:rolleyes:

    Look at the specified mission profile of the F-22 about that and the quoted range of the F-22 with two ETs and subsonic. At Mach 1,5 it covers a distance of 27 km per minute. 10 minutes does give 270 km or 146 nm. What was the mission profile from an AB in the UK and a few minutes combat over Germany?
    😉

    http://www.f22-raptor.com/technology/data.html

    Radius implies that there’s also a return trip, so multiply those figures by 2X.
    It would appear that the F-22 can spend about ~ 1/3 of its time supercruising.

    It may be for new missile. larger than R-77 but smaller than R-37. They are increasing the range of new R-77 three to four times. so larger seeker with bigger FOV is needed.

    Here’s the important take aways that I read in that article.

    “We have a 350 millimeter [13.8-inch] seeker in addition to the 200- millimeter and the new 150-millimeter model. They are all the same basic design, but as we move up in diameter we add larger antennas, which provide for more range.”

    There’s no mention of the missile that the 350mm seeker is going into. I guarantee you it won’t be an R-77 at 13.8 inches in diameter.

    Another important tidbit-

    “Since the performance of any active-radar sensor is related to the aperture size (area) of the antenna, the reduction in antenna diameter that results from the smaller antenna of the 9M-1103M-150 inevitably means that the maximum lock-on range of the new seeker is less than that of the larger 9M-1103M. Against a target of 5 m2 radar cross-section, the new seeker has a maximum lock-on range of 13 km, while the larger 200 mm-diameter seeker can manage lock-on at up to 20 km range against a similar target.”

    What do you suppose the lock on range against a target in the <.001 or .0001 RCS would be? <1km? .5km? .1km?

    The next question you need to ask- how far away will the F-35/22 pilot be able to detect the incoming missile(especially after its seeker goes active)?

    One last question- can you point us to the source that says the R-77 is getting a 300-400% range increase? It certainly wasn’t in that article.

    thats ur assumption. Russia Radar scientist have clearly claimed they can see Stealth. and u cannot certainly challenge instituional claim of Sukhoi, MIG and Ruaf. It is backed up by centuries of scientific discoveries. not some imported knowledge.

    Translation. Undistinguished planes, hypersonic intercepts. range exceeding 200km. (offcourse real range is several times of that)

    The claims I’ve seen are that targets with an RCS of .1-.01 can be detected at 90km. Considering that the F-35 has a lower RCS than that means that figure will be lower, and well within the NEZ of its missiles, by the time the Mig-31 sees it. Oh, and I have no problems challenging claims if there is no evidence to support them.

    True, but can you prove superiority with that? No you can’t! That’s my simple point not more not less. Of course you can interprete the things your way to make the point, but the medal has two sites.

    The Raptor’s requirements were for M1.5 supercruise and M1.8+ top speed.
    We know that both of those were exceeded by a good amount, but we’re supposed to think that the F-35 will barely meet its requirements(or do worse)?

    For a good reason. You guys only compare the F-35s basic config to make your point, but refuse to compare it in other configurations where the F-35 might not be that excellent.

    The likelihood of the F-35 getting 4 kills(or 6 once the new launchers are installed), is higher than a non-LO aircraft getting 8 or more kills. You can’t automatically assume that fewer weapons(in VLO mode only) means less effective.

    A typical guessing. To have some usefull range from the F-22, it is limited to a few minutes of supercruise only, when you still post the claims from the beginning of that program.
    Even that high speed values about supercruise are limited to a given height only. At low level a F-22 is limited to 800 kn IAS and is in need of AB to keep that high up.
    http://www.lockheedmartin.com/products/f22/f-22-specifications.html

    Where in that link did it mention how long the F-22 could supercruise? Even conventional fighters can fly for a few minutes supersonically, but at a much higher fuel usage. The whole point of supercruising is that the Raptor isn’t having to use afterburner to achieve this, which means its persistence will be much longer than a few minutes.

    The inlet-system is the limiting factor of the F-35, when it comes to speed and nothing else. At least, when the chase-planes are with ETs and the real TOW of the F-35A not quoted. 😉

    I’m pretty sure that the test pilots have taken these things into account, when they’ve made their remarks. Otherwise they might say that it flies much better than an A-7, which is what many here are inclined to believe is more indicative of the performance levels.:cool:

    Look into a Su-30 about that and you will be surprised. When someone is intrested into a realistic way, there is no shortage of data around to figure it out yourself. 😉

    I’ve seen a wide varation of figures for the Flanker’s(SU-30/35) range, which is why I brought it up. Some as low as 3600km, some saying 4000, some saying 4000 with 2 external tanks. The combat radius figures were more stable at around 1500km.

    This comes directly from a LM document

    It doesn’t say combat load or anything else. Though the same document claims >590 nm combat radius. So we basically can assume a higher max range, but the document doesn’t say so. It’s not new that initial range data are often much lower (published) than they actually are. So far we can work with that data only however and make assumptions at best.

    I think it’s safe to say that if the max range really were 1200 miles, then the combat radius wouldn’t be 590-600 miles, unless the plan was to run out of fuel on the way home. The spec sheets tend to be on the conservative side.
