Since February 1966 the main opponents of the F-4 were the supersonic MiG-21F-13 (some of them - in Czechoslovakia) and MiG-21PF-B (all-weather option that is equipped with a radar sight MiG-21PF in the "tropical" version), so well as the American aircraft equipped with missiles - SD R-Sc with CBC or blocks with a 55-mm unguided rockets (NAR), C-5. The Air Force and the U.S. Navy continued to place high hopes for the F-4, assuming that the powerful weapons, perfect onboard radar, high-speed and acceleration capabilities, combined with new tactics will provide "Phantoms" superiority over enemy aircraft. But in collisions with lighter MiG-21 F-4 began to suffer defeat after defeat. From May to December 1966 the U.S. air battles lost 47 aircraft, destroying only 12 fighters. Say a big load on a wing and a few smaller (especially at medium altitudes) angular velocity reversal of American fighters (the Americans subsequently acknowledged that "Phantom" generally inferior Miguev cornering), restrictions on the operational overload (6.0 versus 8.0 in the MiG -21PF) and the allowable angle of attack, and controllability of the worst American cars. Did not have the F-4 and the advantage thrust-weight ratio: at normal take-off weight, it was 0.74 in F-4B, ​​and the MiG-21PF - 0.79. The disadvantages of "Phantom" in the first place should be attributed poor spin characteristics. There was the possibility of getting into a flat spin, out of which the pilot of average skill is practically not possible. It was reported that only until 1971 because of falling into a tailspin lost 79 "Phantoms". Onboard RLSamerikanskogo fighter though and had a long-range detection and capture, but had a relatively low noise immunity. Cockpit and operator were saturated with numerous devices and switches. At the same time, the merits of "Phantom", manifested in Vietnam, it is necessary to carry a slightly better acceleration capabilities (F-4E accelerated from a speed of 600 to 1100 km / h in 20 seconds, while the MiG-21PF - for 27 s), more a high rate of climb, the best view from the cockpit and the availability of the second member of the crew, who watched the traffic situation and promptly warned the commander of the threat from the rear hemisphere. The disadvantages of the MiG-21 should include short range radar sight (no more than 10-12 km Target type fighter), a great time for a complete cycle of the review board radar, do not take the blip on the indicator in the cockpit, the lack of visibility from the cockpit. To switch weapons options the pilot had to take off one of the hands from the levers of control of the aircraft. Engine fighter in the individual operating modes strongly smoked that unmask plane (in clear weather MiG-21 could be detected at a distance of 30 km). The first fight with MiG-21 took place in Vietnam April 23, 1966 and ended without result. And on April 26 "Phantoms" was able to knock down the first MiG-21, opened the scoring in the match these fighters, which lasted on the fronts of many local wars over more than two decades.
