The first Soviet fighter to utilise wing sweepback, and consequently known unofficially as the Strelka (Dart), the La-160 featured 35° of leading-edge sweep on a wing of 9.5% thickness. When initially flown on 24 June 1947, the La-160 was fitted with an RD-10 turbojet rated at 900kg, with which it could not get airborne fully laden. After initial handling trials, the La-160 was fitted with an RD-10F which provided an afterburning thrust of 1170kg and with which, after diving and then levelling off, a speed of 1060km/h was allegedly attained at 5700m, this being equivalent to Mach=0.92. The La-160 carried an armament of two 37mm NS-37 cannon, but was utilised primarily as a research vehicle in the development of more advanced fighters.
