    With the exception of the MiG-25 all fighter speeds above Mach 2 are brief ones only for a very short dash.

    I’m convinced the MiG-31 has the same capability, even more so (longer range at those speeds) with its more efficient turbofan engines?

    OK, look at the F-15 victories in Isreali service. Isreal has done quite well with a small number of F-15s, and I believe Isreal has more F-15 kills that USAF or Saudi F-15’s. Numerous kills, mostly MiG 21 and 23, which I’m sure some here will say “so what, those are older planes”. I say the record speaks for itself, and is impressive by any means. Isreal uses a western doctrine, but does not have the same level of support from E-3 or E-2 that the US does.

    They actually did operate E-2s which were a key to the success (among other factors, of course) the F-15s and 16s enjoyed over the Bekaa in 1982. with the Syrian GCI sites destroyed and/or jammed.

    The A-10 is the only obvious choice here for the most part, IMHO. Besides offering good enough capabilities for medium altitude operations as its competitors (e.g. F-16), it offers long loitering times, good low altitude maneuvering capabilities along with ample ammunition for the highly precise cannon for direct anti-infantry support and a unique capability to take some AAA punishment. Only the UAVs and light attack aircraft (like in the lines of the before mentioned Scorpion) would be more cost-effective for surveillance and interdiction missions. The attack helicopters have a somewhat limited range so it depends how close their FARP would be, plus they are much slower and more vulnerable during transition to the mission area.

    So SARH missiles cannot engage maneuvering targets? ROFL. If you are strictly comparing ARH vs SARH, by which I mean excluding INS or mid course updates, SARH missiles are FAR more suited to engage maneuvering targets at long range.

    If you’d care to actually read my post, you’d notice that I was referring only to R-33, not the SARH missiles in general. The MiG-31 uses a passive phased array radar which can guide missiles to four different targets, but it guides SARH missiles (unlike Western radars which would guide ARH missiles via mid-course updates) and this method of target illumination is supposedly not really fast enough to illuminate maneuvering targets with sufficient frequency so the missile’s seeker can stay ahead of the target when it gets close to it. Then there is also the size and the weight of the missile which would probably cause the missile to bleed most of its energy trying to stay ahead of the maneuvering target, but OK, the target would have to know it’s under the attack in the first place. These limitations were probably acceptable as the MiG-31’s primary targets are only bombers and cruise missiles.

    And I do say supposedly as this is what I’ve understood from what I’ve read. Some missile guidance engineer with the knowledge of the R-33 seeker’s guidance logic and the details of the Zaslon radar could probably give a much more precise and valid explanation..

    What makes you think that some of the high value assets that it is called to intercept will not lie within the AA cover range of the enemy? Especially ship to air ones. AWACS don’t venture that far into one’s territory nor do tankers.

    IMHO, it’s only an interceptor – made for intercepting bombers and cruise missiles as quickly as possible over vast friendly territory. It was not made for missions over enemy controlled territory, Su-27 was made for that. Hence why it doesn’t even have an ECM system.

    Just because someone previously mentioned AWACS and tankers as part of its primary mission, doesn’t mean it’s necessarily true.

    Now, perhaps some offensive missions were considered as an option for the MiG-31M (it was to have the ECM system on the wingtips and the R-37 missiles would have had active guidance so it would be possible to engage maneuvering targets unlike with the R-33S), but it was shelved unfortunately.

    There are multiple reasons why Russia is already wanting a replacement of the Foxhound.

    The main reason is fleet’s age and thus limited flight hours remaining. The rest can probably be solved via updates.

    A better question is, how vulnerable is the MiG 31 to modern air defences.

    It’s a pure interceptor for RuAF, not an air-superiority platform so this is not relevant at all.

    IDK about R-24T; but R-27T/TE versions are technically not LOAL; they can be fired without lock command but the aircraft itself must maneuver to align missile’s seeker to the target. I am reasonably sure relatively obsolete R-40T and R-24T missiles operate in same fasion. Such implementation would be much simpler, and for BVR shots, it would be pretty effective still.

    You’re totally right about the LOAL term, but I would still like to see some proof that the mentioned IR variants were actually intended to be launched that way (i.e. without a proper lock) operationally. Yes, there is an override so that they could be launched without a proper lock, but AFAIK, it was intended for jettison purposes since these missiles are carried on rail pylons, not ejector ones, so they cannot be simply jettisoned. The sources I’ve seen indicate that the seeker must be locked on before launch (e.g. to be able to lock the target, it also needs to be cooled down first using the cooling liquid from the tank located in the pylon).

    Ljozic, not sure what you are trying to say. IR missiles can be launched blind, with the seeker slaved to where the radar expects the target to be. The problem is the seeker may not track the intended target. And you realize semi active and active radar homing seekers operate completely different. The missile seeker on SARH has to be locked on before launch to be effective. The seeker on ARH requires mid course updates near its apex or it will have a tiny chance of interception.

    The quoted part is the hint that the context is clearly limited to the R-23/24 family of missiles. I did in fact misuse the quoted LOAL term in my post, but from what I’ve read on some forums, the R-23R SARH seeker RGS-23 (maybe R-24R, too) seems to be technically locked on to the target three seconds after launch to avoid interference from the radar, albeit the seeker is turned to the direction of the target before the launch.

    Regarding the IR variants, the seeker can be slaved to the radar so that the proper target is locked on, but still needs to be locked on before the launch.

    As Lukos has reminded us, the R-24T R-23 and R-24 (AA-7 ‘Apex’) series of missiles used on MiG-23 versions equipped with the Safir radar did have LOAL capability. In the early stages of flight, they used command guidance. But most LOAL weapons rely on inertial navigation system rather than command guidance, so had to await the availability of lightweight inertial technology.

    IIRC, the IR variants are LOBL, while the radar variants do not use command guidance (no air to air missiles use this but the earliest ones, unless you’re referring to the mid-course updates, but these missiles have no datalink), but the lock-on is delayed till after launch to avoid interference caused by the main radar’s sidelobes to the missile’s seeker.

    It would be safe to assume that most of the Ukrainian air force was there prior to split, as you can’t exactly train people to fly modern fighters in 3 months from scratch. As such they trained with Russian counterparts, therefore not entirely incompetent and perhaps more competent than the Serbian pilots during Operation Allied Force. Probably with functional aircraft too. I believe that covers 1,2,3,5 and 6. At least one Su-25 and one MiG-29 were flying fairly high. Kiev thought the Su-25 had been shot down by a Russian jet until the Buk story broke. That covers 4.

    Wow, nice coverage, not. You provide no relevant data to base your conclusions on. The fact Ukraine was a part of USSR 25 years ago doesn’t mean anything for their CURRENT pilot skill level. IIRC, most of their planes are not in flyable state as the budget is pretty tight. Probably same goes for the number of flying hours the pilots get.

    And you still don’t know what missions and mission parts the planes were flying on when they were shot down (e.g. was it a low-level CAS) and how skillfully were they employed. Besides, since the Ukrainian Air Force has only a few somewhat modernized Su-25s, the ones shot down were probably basic old models whose RWS system is old, has no jamming equipment and has no way of detecting IR missiles, unlike the current A-10C discussed here.

    Agree that they deserve their own nation. But the strongest opposition to a Kurdistan will come from the Turks, who have oppressed them systematically over several decades.

    They changed their views in the last 3-4 years and are now the major investors into the Kurdish areas of Iraq. If the Kurdish part of Iraq becomes independent, it will be because of the Turkish support (who else will support their independence?), not because of their opposition.

    Despite early apprehension about the impact of Soviet-era Stingers in Taliban hands, very few ve hashown up during the US campaign in Afghanistan. Consequently while the ISAF did take some casualties to MANPADS, the scale has been relatively small. Put a substantial number in the hands of professional or even semi-professional army and the A-10s are going to take a hammering. Limited utility on the modern battlefield.

    Well, there are certainly a few or more in Taliban hands and the A-10s didn’t get hammered after all those years. So, excuse me if I doubt the nullifying effect of that old system (Strela 2M or its copies) with its limited engagement capabilities and low flare resistance.

    They only had camels not Iglas and Strelas.

    Yeah, right.. Like there were no Strelas in Afghanistan from before (although, not sure what’s the shelf life on these) and they couldn’t get any (or Chinese copies) from Pakistan or Iran.

    Agreed. Afghanistan-style strafing runs can be thwarted by Iglas and Strelas

    Why didn’t it happen in Afghanistan then?

    For expeditionary forces like the Royal Navy and USN the optimal fighter is short and requires short runways so you can fit as many as possible on as small ships as possible. So for that the F35 is a perfect match.

    Do you mean USMC instead of USN perhaps? The US Navy would probably appreciate having much longer legs, especially for potential deployments against countries with advanced long range anti-ship missiles.
