Kosmos 380 was successfully launched into low Earth orbit on 24 November 1970, with the rocket lifting off at 10:59:56 UTC. The launch took place from Site 133/1 at the Plesetsk Cosmodrome, and used a Kosmos-2I 63SM carrier rocket. Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-100A.
Orbit
Kosmos 380 was the thirty-seventh of seventy nine DS-P1-Yu satellites to be launched, and the thirty-fourth of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of 197 kilometres (122 mi), an apogee of 1,374 kilometres (854 mi), 81.9 degrees of inclination, and an orbital period of 100.6 minutes. It remained in orbit until it decayed and reentered the atmosphere on 17 June 1971.
