SM-12PM

This experimental interceptor, powered by two R3-26 turbojets, was also built in 1957. Like the SM-12/3, the air intake on the SM-12PM had a two-position nose dome, but this one was much more bulky because it had to house the TsD-30 radar antenna.

Instead of cannons the SM-12PM carried two RS-2U air-to-air mis­siles on wing pods. Its maximum speed reached 1,720 km/h (929 kt), and its service ceiling was 17,400 m (57,000 feet). It could climb to

10,0 m (32,800 feet) in four minutes. Its maximum range without drop tanks was 1,700 km (1,055 miles).

The SM-12/1 and SM-12/2, built at the same time as the SM-12/3, differed only in their equipment. The reshaping of the engine air intake foreshadowed already that of the MiG-21.

The SM-12PM had a much larger nose cone than the MiG-19. The two air-to-air mis­siles are of the RS-2U type.

The SM-12PMU had a new power plant, including a rocket engine, and was armed with two RS-2US (K-5M) air-to-air missiles.
