Resembling a scaled-up MiG-17, the I-350 had a long slim fuselage, mid-set 57° swept wings and a wide-chord fin mounting a tailplane at half-span.
[citation needed] Given the OKB designation Izdeliye M, it was the first Soviet fighter able to fly stably at supersonic speeds.
[citation needed] The I-350M-1 first flew on 16 June 1951, piloted by Grigoriy A. Sedov, but the engine failed shortly after takeoff, precipitating a hydraulic system failure.
Four more test flights were made, with very poor engine reliability, before the I-350 programme was terminated in August 1951.
