Mikoyan-Gurevich I-350

The I-350, given the bureau designation Samolet M or Izdeliye M, was a Soviet Cold War experimental fighter and the first Soviet aircraft able to maintain supersonic speed. Mikoyan-Gurevich designed it around the new Lyulka TR-3A axial-flow turbojet, later redesignated AL-5, and it resembled a scaled-up MiG-17 with a long slim fuselage, mid-set wings swept at 57 degrees and a tailplane at half fin height. The first prototype carried an RP-1 Izumrud interception radar and the second a Korshun radar. The I-350M-1 first flew on 16 June 1951 but its engine failed soon after takeoff, and after four more flights with very poor engine reliability the programme was ended in August 1951.
