The Lavochkin La-160, known as Strelka (Arrow), was the first Soviet swept-winged jet fighter research prototype.
Although designed as a fighter, Aircraft 160 was intended for research into high-speed swept-wing flight, of which little was known in the mid-1940s - only the 1945-era light, piston-engined MiG-8 canard had used even a moderate degree of wing sweep before this.
Following closely the layout of his previous jet-fighter prototypes Lavochkin was able to produce an aircraft capable of providing useful data and experience of high-speed flight near the speed of sound.
Successful flight trials were quickly followed by public display at the 1947 Aviation Day airshow at Tushino.
Trials continued until Aircraft 160 broke up in flight, due to wing flutter, during tests to establish the maximum attainable speed.
