Kosmos 380 (Russian: Космос 380 meaning Cosmos 380), known before launch as DS-P1-Yu No.26, was a Soviet satellite which was launched in 1970 as part of the Dnepropetrovsk Sputnik programme. It was a 250-kilogram (550 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]


Kosmos 380 was successfully launched into low Earth orbit on 24 November 1970, with the rocket lifting off at 10:59:56 UTC.[2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome,[3] and used a Kosmos-2I 63SM carrier rocket. Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-100A.[4]


Kosmos 380 was the thirty-seventh of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirty-fourth of seventy two to successfully reach orbit.[5] 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.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 17 June 1971.[6]
