If there is one thing people should worry about above anything else then that is the performance of A/A guided missiles. Almost everything in modern air to air theory depends on it (especially long range stealth engagements). And the real world results from the past don't look that impressive. quote:
AIM-7 Sparrow was thoroughly tested by USAF, and in R&D tests it achieved Pk of 80-90%, with operational tests resulting in Pk of 50-60%. In Vietnam, Pk dropped to 8-10%, with many US pilots firing entire AIM-7 loadout, from visual range and from perfect tail position, only to watch all missiles miss. AIM-9B achieved 15% Pk, which increased to 19% for USN AIM-9D. USAF used AIM-9E and J which scored Pk of around 20% less than B and D models, 12% – 15% Pk. Soviet copy of AIM-9B missile, Atoll, achieved 12% Pk. Radar-guided missiles fared worse. AIM-7D achieved Pk of 8%, which increased to 10% for AIM-7E. AIM-7E2, introduced in last year of the war to correct AIM-7Es fusing problems, achieved Pk of 8%. Despite having long spin-up time, M61 20 mm rotary cannon achieved Pk of 26%. Out-of-envelope launches only resulted in 7% of non-kills, and 46% of attempts were failures to launch or guide, compared to 30-37% failure rate of AIM-9. In Indo-Pakistani war of 1971, Pakistani gun- and Sidewinder- -armed F-86s achieved 6:1 exchange ratio against Indian MiG-21s, Sn-7s and Hunters. Subsonic Folland Gnat, smallest fighter in the world, managed to kill several F-86s without suffering losses. Immediately after the 1973 Arab-Israeli war, claims were made than 1/3 of Israeli 251 air-to-air kills were due to Sparrow, and that Sparrow achieved Pk of 50%. As it turned out by 1978, only 12 Sparrows were fired, achieving either none or a single kill, with majority of Israeli pilots refusing to carry Sparrow at all. Only 4 of these firings were made from beyond visual range, and a single kill made might have been from beyond average visual range (5 nm) despite the fact that Israel does not claim it as a BVR kill. As many large fighters are visible well beyond 5 nm (up to 15 nm if engine smokes heavily) it is possible that kill in question was a visual-range one. Out of remaining kills, 2/3 were made with IR missiles and 1/3 with guns, according to statistics avaliable; Israelis however credited 2/3 of their air-to-air kills in both wars to guns or to guns aided by initial missile launch. Syrian pilots hated MiG-23 and considered it a worse fighter than MiG-21. Israeli general Hod stated that in 1973 war radar was “essentially useless” and that only one or no kills were made by radar-guided missiles. In Bekaa Valley in 1982, 8 kills were with guns, 54 with IR missiles and 12 with radar-guided missiles; more than half of kills were made by “multirole” F-16 despite it being primarly tasked with bombing missions. All radar-guided missile kills except one were from visual range. Total of 5 BVR shots were made, making data range very low. It is known however that Syrian pilots were rather incompetent, with Israel winning 73-0 victory. After the war, Israeli General Mordecai Hod had stated that. had Israelis swapped planes with the enemy, outcome would have been the same. In Falklands war, British have achieved 19 kills in 26 launches, for a Pk of 73%. Harriers themselves saw little fighting after first day, and almost all kills were against bomb-loaded aircraft. Further, Harriers used only IR missiles, majority of which were fired from rear hemisphere, thus achieving surprise. Argentine pilots did not try to outmaneuver missiles – even when they did notice they were being fired at, they used Vietnam war tactics which did not work with all-aspect missiles used by Harriers. At the same time, all Argentine radar-guided BVR Matra missiles missed. During entire Cold War, only 3 or 4 air-to-air kills were made from beyond visual range out of 60 – 61 shots made at beyond visual range, for Pk of 5 – 6,6 %. All BVR kills were carefully staged outside combat. Combat results from 1991 and 2003 invasions of Iraq and 1999 war in Yugoslavia are used to prove that AIM-120 can achieve BVR dominance. Yet these are misleading even if actual statistics are true. Serbian MiG-29s were suffering from lack of spares since 1996, and resources were spent on riot police instead of maintaining aircraft; their pilots were flying 20 hours annually. To put this into perspective, US pilots even at worst of times flew more than 10 hours per month. Systems on MiG-29s were malfunctioning; on most aircraft, neither radar nor RWR functioned. Despite that, some pilots managed to evade several BVR missiles. One MiG-29 shootdown attributed to AIM-120 could also be a case of Serbian SAM engaging in fratricide; that would make it 5 kills in 13 launches, a Pk of 0,38. As for Iraq, situation was similar with its air force in both wars, with pilots usually failling to take any evasive action once radar lock occured. Thus it is logical that USAF success rate would be similar, and it was. In Desert Storm, 41 USAF aerial victories were achieved with anywhere between 5 and 16 kills made at beyond visual range. 2 kills were made with guns, 10 with IR missiles and 24 with radar-guided missiles. 88 AIM-7 shots were made, giving a Pk of 0,27. Out of 24 AIM-7 kills, at least 9 were from visual range. For F-15Cs, 12 AIM-9 launches resulted in 8 kills (Pk 0,67), and 67 AIM-7 launches resulted in 23 kills (Pk 0,34). It should be noted that F-16s made 36 AIM-9 launches, of which at least 20 were accidental due to poor control stick ergonomy, and made 0 kills. US Navy F-14s and F-18s fired 21 AIM-7s for one kill, and 38 AIM-9s for two kills. Between Desert Storm and Allied Force, USAF achieved 3 kills with AIM-9 and 3 with AIM-7, with at least one AIM-7 kills being visual range. Further, on Jaunary 5th 1999, two MiG-25s (equipped with radars for a change, which they used to illuminate US fighters) violated southern “no-fly” zone, and succeeded at evading 3 AIM-7, 1 AIM-120 and 2 AIM-54 missiles, all fired by US fighters from beyond visual range.
