Characterised by what was at the time extreme wing sweepback - 60° at the leading edge - and the first MiG fighter designed for sustained supersonic flight, the OKB's Izdeliye M was initiated to accept the new Lyulka TR-3A single-shaft turbojet which was to be committed to production as the AL-5. Assigned the official designation I-350, one prototype was built, the M-1 with RP-1 Izumrud AI radar, a second, the M-2 with Korshun AI radar, being abandoned before completion. Armament comprised one 37mm N-37 and two 23mm NR-23 cannon. The M-1 was flown for the first time on 16 June 1951, but the TR-3A turbojet, which was rated at 4600kg, failed shortly after take-off. The hydraulic system also failed, but the pilot nonetheless effected a successful landing. Four further flight tests were performed, but engine difficulties persisted, and, as it was obvious that the Lyulka turbojet demanded considerable further development, the I-350 programme was terminated in August 1951.
