Kosmos 408 (Russian: Космос 408 meaning Cosmos 408), known before launch as DS-P1-Yu No.37, was a Soviet satellite which was launched in 1971 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 408 was successfully launched into low Earth orbit on 24 April 1971, with the rocket lifting off at 11:15:02 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 1971-037A.[4]

Kosmos 408 was the forty-first of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirty-seventh 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 1,383 kilometres (859 mi), 81.8 degrees of inclination, and an orbital period of 100.66 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 29 December 1971.[6]
