UTI MiG 15P / ST-7
The VVS needed a two-seater to familiarize pilots with the operation of the RP-1 Izumrud radar. For this purpose the nose of the UTI MiG-15 was modified to resemble that of the MiG-15P bis (SP-5). The instrument panel of the student’s cockpit in front was identical to that of the single-seat fighter.
The armament on this trainer was limited to one 12.7-mm UBK-E machine gun. The ST-7 passed its acceptance tests in 1952, but its production run was limited. Its flight performance did not differ significantly from that of the UTI-15.
