Launch
It was launched aboard a Kosmos-3M carrier rocket,[3] from Site 132/1 at the Plesetsk Cosmodrome. The launch occurred at 21:45:00 UTC on 18 March 1971.[4]
Orbit
Kosmos 400 was placed into a low Earth orbit with a perigee of 990 kilometres (620 mi), an apogee of 995 kilometres (618 mi), 65.8 degrees of inclination, and an orbital period of 105 minutes.[1] It was successfully intercepted and destroyed by Kosmos 404 on 4 April.[2] As of 2009, debris is still in orbit.[5]
Kosmos 400 was the third of the five original DS-P1-M satellites to be launched,[1] of which all but the first were successful. Following the five initial launches the DS-P1-M satellite was replaced with a derivative, Lira.[6]
