    Large SAM bodies don’t appear to suffer the same shortfall of a heavy AAM body. It must be different magic pixie dust on the SAM body.

    I don’t know where you got that idea honestly. Long-range SAMs of 60s and 70s vintage were also very minimally capable against fighter class targets, especially at long ranges.

    This is a good read and, ahem, informative on the Mig-25. Viktor Belenko and CIA assessment of the Mig-25p he flew to Japan in 1976.
    http://www.testpilot.ru/review/mig_pilot/ch_7.htm

    From the link:

    In fact, as a fighter, the Foxbat is barely equal to our 15-year-old McDonnell F-4 Phantom and it is hopelessly outclassed by our new generation McDonnell F-15 and General Dynamics F-16. Either of our two newer Air Force fighters can outclimb, outaccelerate, out-turn, out-see, out-hide and out-shoot the Foxbat by margins so wide that our expected kill-ratio advantage is almost incalculable. No U.S. F-15 or F-16 pilot need fear the Foxbat unless he is asleep, out-numbered or an utter boob.

    But Belenko explained and his plane proved that the MiG-25 was not a fighter, not an air superiority aircraft designed to duel with other fighters. Against Western fighters, it would be, as Representative Carr claimed, virtually helpless. But the Russians never intended it to tangle with hostile fighters.

    In a MiG-25 Belenko took off against an F-15. Before they reached 50,000 feet, the F-15 shot him down four times, but at about 60,000 feet the MiG-25 accelerated upward and out of range of the F-15.

    The combat exercises, each one of which cost $10,000, according to information given Belenko, spanned three days. The results were complex, required lengthy computer [184] analysis, and remain highly classified. But this much can be said: While the F-15 demonstrated its clear superiority over the MiGs, Belenko as a pilot demonstrated himself to be fully the equal of the American fliers against whom he competed.

    So again, the Mig-25/31 were designed as interceptors, to target bombers and cruise missiles… in an engagement against a real fighter the best likely outcome for the Mig would be to escape, something it did show itself to be adept at due to its speed and altitude capabilities.

    And it looks like we are done here…

    Anything can be compared, real life effectiveness or economics or etc can be discussed to death. However technical/technological comparison is plain stupid. Each generation of fighers are designed to defeat the previous generation.

    When two aircraft enter service separated by only 3-4 years it is reasonable to compare them. Especially if those two aircraft subsequently see combat against each other with one of them decisively beating the other. (F-14 over Mig-25 in Iran/Iraq war)

    And you are grossly underestimating the other advantages of MiG-25/31 have.

    No, I am really not. The Mig-25/31 are fast, and that is it, period.

    MiG-25 was fast, PLUS, it had better sensors (Smerch Radar +Lazur datalink vs APQ-120), missiles (R-40R/T vs AIM-7D/E) , and supersonic kinematics in all parameters (climb, acceleration, top speed, ceiling), at the cost of *slightly* worse supersonic maneuverability. I don’t get what part of this do you not understand?

    I don’t really see any reason to believe the Mig-25/31 had better sensors than its Western competitors. It certainly had a big radar, but the Soviets consistently lagged the West in both radars and computers.

    I would certainly give the edge to the West in missiles. The R-40 was again big missile, but totally unsuitable for use against fighters. It was optimized for use against big unmaneuverable targets at long range. The simple fact that even against its intended targets Soviet doctrine called for two to be launched at each target doesn’t suggest great faith in the missile on the part of the Soviets. The AIM-7 for all of its initial struggles in Vietnam ultimately proved a very effective weapon accounting for numerous kills in multiple wars.

    The Mig-25/31 did not have an advantage in acceleration, speed, or ceiling except under the narrowest of circumstances, circumstances that would not occur in the real world. You have to separate spec sheets from reality. You don’t enter an engagement at M2+ and 50K+ feet…

    I don’t disagree about the mission of MiG-31, I point out, the qualities it posses do make it a good BVR platform, there is a difference.

    Again lets compare 1990’s F-15 with 1990’s MiG-31;

    -Sensors: APG-63 versus Zaslon is laughable comparison from the start. Plus, F-15 had no datalink in 1990s, whereas MiG-31 had two way datalinks to both other aircraft and GCI controllers. When working together, one side will have AWACS-like situational awareness, excellent coordination between aircraft, otherside wont.

    -Missiles: At the fall of SU; F-15 had only AIM-7Ms, MiG-31 had R-33, R-40R/T missiles at its disposal. While F-15 has TWS, it could engage only 1 target at the same time. MiG-31 can engage 4 targets with R-33s, plus if range allows IRST lock, additional two with R-40Ts. MiG side has option to firing its missiles much earlier, or wait for the effective kill range; Combined with sensor advantage, MiGs can split-up, some providing target illumination with their multi target engagement ability, some launching their missiles at shorter ranges; kinematic advantage would shrink AIM-7s already tiny effective range, and allow MiGs more room to close-in or withdraw at will.

    -Kinematics: When supersonic; MiG-31 had better climb acceleration top speed, and ceiling; it also had superior sustained turn performance but inferior instantenious turn performance due to lower G limits. This combined with sensor and missile advantage, will ensure MiG side stays at much higher energy state, able to outrun missiles. F-15 do have superior ITR, having 0,5 deg/s superior turn rate at M1.5 wont help evading a missile anyway.

    Much of this is quite simply factually inaccurate, particularly your characterization of the relative kinematic performance. Top speed is not the same thing as acceleration.

    The F-15 will out-accelerate the Mig-25/31 anywhere under M2. Similarly it will crush the Mig-31 in both sustained and instantaneous turn performance anywhere where a fight might actually take place. The 1991 engagement between the F-15s and Mig-25s is a perfect example of what you could expect. The Migs entered the fight faster, but were on the defensive from the first turn and were shortly shot down. The best possible outcome for the Migs would have been to escape… at no point did they have the prospect of actually getting into a position of advantage themselves.

    By 1992 the AMRAAM was operational, and a Mig-25 provided the first demonstration of its efficacy.

    So really, what advantage does F-15 have? Bias aside in late 1980s, a flight of MiG-31 would have simply played with equal number of F-15s at BVR.

    Your devotion to your version of reality is kind of endearing in a way, but it has little to do with the real world. There hasn’t been a single window where sending Mig-31s against F-15s would be a good idea. What part about the Mig-31 being designed to engage bombers and cruise missiles is lost on you? Its principal armament would very likely be next to useless against an F-15 and we already know the reverse is not true. Further, if the US agreed even slightly with your assessment they would have developed a counter to the Mig-31 back in the 80s….

    I find it somewhat amusing after the endless talk about the supposed death spiral facing the F-35 that when the Gripen loses some 20% of its total orders in a day that all people around here seem to have to say is “well, more workshare for everyone else… “

    No-one disputes the fact that the Rafale is a great airplane, and more potent (imho) than the Gripen C/D. However the future Gripen will be a new plane, designed 20 years (+) after the Rafale… hence in that context, the Gripen is the coolest plane simply because it’s new.;)

    The Gripen E is not a new plane, it is an extensive upgrade to an existing design, similar to what was done with the F-16 Block 60.

    Just an addition to your post – its mission is/was not only to intercept bombers, but (even more importantly) cruise missiles as well. This is why it needed an advanced radar suite capable of tracking low flying cruise missiles and guiding long range missiles at multiple targets simultaneously. And I guess this is why they will upgrade it and even develop a successor as the cruise missile threat gets ever more significant with the Arctic polar cap melting.

    True

    In my youth, before computers were common, my friends and I amused ourselves by playing board games that attempted to simulate air combat. One of the scenarios that we found interesting was to see how one could use the Mig 25 effectively.

    I think what muddies the evaluation of the 25 is the labels that were put on it by the west which were not true. The Mig-25 is a bomber interceptor that like the F-106 thankfully never had to be used in the role it was intended.

    I found that when used against tactical aircraft it was best to think of it more like a manned SAM rather than an air superiority fighter. You would never use them to fly out and meet the enemy head on in the classic 4 v 4 head on joust that everyone seems to imagine air combat is. Ideally you would launch them in the confusion of an air raid and use GCI guidance to dash out and take a shot and then beat feet. Not a war winning strategy but it was the best attempt at putting a square peg in a round hole.
    Looking at the Mig 25 with the understanding that the countries that actually used it in combat were not any where near as well trained as most of their opponents, the Mig-25 looks less horrible when you compare what Mig 21s, 23s, and 29s managed to do.
    Bottom line is the 25 is the last of those aircraft I would want to go into war with but it was never designed to do that type of mission.

    You are right that the Mig-25 wasn’t intended to engage fighters, but it was used in its intended role in 1991 when Iraqi Mig-25s tried on several occasions to engage high value coalition assets without success. (and the loss of two Mig-25s)

    The Migs proved capable of harassing the coalition air forces, in some cases forcing jamming aircraft to draw back, and they successfully wasted a lot of missiles. (both theirs and those of the fighters opposing them)

    All in all, a less than impressive showing.

    I meant Cost/impunity ratio. It was much cheaper to build and operate when compared to SR-71, yet just as survivable. It possibly was expensive than Mirage F-1CR but it provided exponentially greater survivability.

    I don’t know how you could conclude that it was “just as survivable.”

    As valid as comparing 4th gen F-16 (still in production) to 5th gen F-35, or 2nd gen MiG-21 (still in service) to 5th gen F-22. I understand your point, but I disagree. What is truly comperable to F-14/F-15/F-16 is MiG-31. Then again, until the introduction of AIM-120A in 1991; MiG-31 had better radar+datalink, better missiles (at least equivalent to AIM-54), and better BVR kinematics than all those types. Maneuverability? F-15C has a supersonic G limit continiously varying from 4.8 to 6.6Gs between 20k to 40k feet and M1.0 to M2.2; MiG-31 had 5G limit throughout its envelope. It has excellent supersonic sustained turn performance; able to pull 5,6 deg/s at M1.4 (altitude not given), compared to F-15C’s 5,2 deg/s. Except the fact 4th gen aircraft do posses some ability to evade R-33 missiles, what I’ve said about F-4/5 vs MiG-25 is also true for F-15/16 vs MiG-31. However in last 20 years, F-15/16 continiously get upgraded, and MiG-31 didn’t.

    It does make sense to compare 4th and 5th generation fighters. There are endless threads about exactly that on this board.

    …and again, I think you are grossly overestimating the Mig-25/31’s advantages over their contemporaries and the implications of those advantages. The Mig-25 was fast, but a dog in every other respect. It was designed to attack bombers, and avoid fighters. The same is true of the Mig-31. It improved on the Mig-25’s weaknesses, but it would be badly overmatched trying to fly against an F-15.

    If MiG-25 is fundementally flawed, then why would russians prefer developing MiG-31 to replace it? They could have easily built more Su-27s?

    Ok, turn your question around now. If the Mig-31 was so great, why develop the Su-27?

    The Mig-31 is an anti-bomber platform. That is what it was built to do, not engage fighters.

    If the Soviets thought they were facing a few F-15s, they would send Su-27s, not Mig-31s.

    Or right now, why they seek to upgrade their MiG-31s, and want to develop a dedicated successor to it? They could simply maintain and upgrade larger portion of their Su-27 fleet, and replace it altogether with PAK-FA, instead of developing a new interceptor. Its OK for western aviation guys say MiG-25 is fundementally wrong; as the reason OR the result of not having something comperable; but Russians must find it useful and they are still happily using them, even at the cost of having less money enough to operate/build/upgrade more of their Su-27s and MiG-29s. This MUST mean something.

    It isn’t clear what the successor to the Mig-31 will be. As for why they are upgrading them… because they have them and they still have a mission.

    Look at it this way. It would be a fairly trivial matter for the US to resurrect a platform like the F-106. (as a clean slate design) A pure delta wing, an F119 or two… a modern AESA radar and perhaps some air launched Patriot PAC-3 missiles… it would be pretty fearsome interceptor… but there just isn’t much demand for such a platform.

    Excluding rare sheer luck events, no aircraft in its own generation (F-4, F-5, Kfir, Mirage F1, MiG-23, Su-15) has been able to succesfully engage the MiG-25. Opposite cannot be said for MiG-25. This means something to anyone with some logic too.

    In combat against F-14s, 15s, and 16s the Mig-25 proved less than impressive. Those are admittedly newer aircraft from a generational standpoint, but all were in production (and of course service) simultaneously with the Mig-25 and are certainly a valid comparison from that standpoint.

    Firstly, no; MiG-25 was designed to go M2.83 with its air to air payload of 4xR-40s. Ability to exceed this speed limit is neither desired or useful feature. MiG-31 could reach M2.83 with 4 R-33s and 2xR-40s. IDK which is faster when exceeding their limits, but MiG-31 is just as fast when on a high speed intercept mission, and could carry more missiles while doing so. At lower part of the flight envelope MiG-31 is considerably faster than MiG-25 too.

    Secondly, even if you weren’t factually wrong, your logic is flawed; Successor or not, MiG-31 is designed to counter much different type of emerging threats. What is good for its time does not mean it will necessarily carry on to the next generation. According to your analogy: as F-35 lacks kinematics of F-16, emphasis on CAC performance is plain stupid, and LM guys corrected their mistake in its direct successor….

    Ask yourself this; what gives an edge in BVR combat? Sensors, missiles, climb rate, speed, ceiling?

    MiG-25 has;
    -much better Radar than ANY of its generation counterparts, it also had one-way Lazur datalink to GCI controller stations, when nothing else had something comperable.
    -better BVR missiles,
    -better climb performance,
    -better acceleration and far better top speed,
    -far higher operating altitude, (higher than the AIM-7D/E’s target envelope)

    than ANYTHING of its own generation. On any slightest criteria means for an intercept mission or BVR combat, MiG-25 has clear edge over its generation counterparts. As for apperant lack of maneuverability, it didn’t matter: F-4Es with 8.5G rated airframes has 5,05G limit at supersonic flight when loaded with 4x AIM-7s and 4xAIM-9Ps and on full internal fuel load. At M2.0 this goes down to 4,6Gs, and at M2.2 its 3Gs. So when conducting an intercept mission or during a BVR engagement, no 3rd gen fighter had a maneuverability to evade an incoming missile. MiG-25P at least has the ability to see first, shoot first, and run away if all else fails. Flying its operating altitude, it has complete immunity to early AIM-7s, R.530 simply because they lack the operating altitude to reach it. In fact, first BVR missiles that could at least capable of reaching a MiG-25P at its operating altidude is AIM-7F introduced in 1976 and Super 530Fs introduced in 1979.

    I don’t know what part of this is fanboyism, but I don’t see a single reason WHY a MiG-25 should prove inferior to its generation counterparts in a BVR engagement?

    The Mig-25 entered service in 1970. Generations are useful when discussing fighters, but absolute dates is what really matters here. The Mig-25 beat the F-14 into service by all of four years, and the F-15 by six years.

    There may have been a brief window when the Mig-25 had a meaningful advantage over Western aircraft, but even if that was the case the advantage quickly vanished.

    In real world engagements the Mig-25 proved anything but untouchable…

    The legacy of the Mig-25, above all else, is that of the wonder plane that wasn’t. For all the hype and conjecture about its capabilities, the reality is that it was a fatally flawed design that ultimately achieved little at great cost.

    So a few shot down is proof, but the many times they avoided any trouble with ease….is not?

    Avoiding trouble? Any fighter can generally “avoid trouble” by running away, which is the main thing the Mig-25 is known for. Its most famous engagements consist of it escaping… but as I mentioned earlier even there its record is checkered.

    There are some good discussions about MiG-25 performance on this forum, and they reached an altogether different conclusion.

    No they didn’t. As always there are a handful of fanboy types who refuse to accept anything but their own personal version of reality but the consensus on the Mig-25 among those who understand the subject is that it compromised far too much in pursuit of top speed. The simple fact that nobody choose to emulate its design philosophy should be evidence enough of that simple truth. Even its direct successor, the Mig-31, accepted compromises in speed in favor of better all around performance.

    I think the 25 was of more use as a recce platform. Also had a SEAD role.

    It was built as a very high speed interceptor and later adapted to act as a recon platform.

    As a dogfighter it is completely useless, the best it could hope to do would be escape, but even there its very high top speed does not necessarily translate into the ability to disengage at will. (as demonstrated by the several Mig-25s shot down in the early 1990s.)

    There has always been a lot of fascination with this aircraft, but its real-world performance has never justified it.

    And what if allies wont arrive? Then it will better for Blue to have superior numbers which are better suited to sustain attrition.

    AWACSs in theatre will change nothing since F-35 is not optimized against L-band/VHF/UHF bands which are used in AWACS AC and is deficient in IR and sound stealth. Which means it will lose its stealth advantage in environment saturated with IR/low-band radars/ground observers.

    Its amazing how quickly some people forgot that Air superiority battle is attrition one.

    Nothing that needs to be debunked again… :stupid:

    Stealth is not a magic “win” button, but it is a huge advantage for aircraft that possess it, which is why everyone with a future in the fighter aircraft industry is working on a stealth fighter design.

    Taking a break from the usual fanboy ranting about X, Y, or Z 40+ year old technology that magically defeats stealth… lets look at some good news on the production front:

    LRIP-9 long lead materials ordered… 57 aircraft. ( http://www.flightglobal.com/news/articles/lockheed-gets-additional-f-35-contract-amid-warnings-of-more-397456/ )

    LRIP-10 contract solicitation issued… 96 aircraft. ( https://www.fbo.gov/index?s=opportunity&mode=form&id=c00095ce8df2f631ad72c65d214740bb&tab=core&_cview=0 )

    If things stay on track it should be in LRIP-10 (or perhaps one year later) that the F-35’s production rate exceeds that of all Western 4th generation fighters combined.
