Kosmos 394
Kosmos 394 (Russian: Космос 394 meaning Cosmos 394), also known as DS-P1-M No.2 is a satellite which was used to demonstrate technology for future satellites which would be used as targets for tests of anti-satellite weapons. It was launched by the Soviet Union in 1971 as part of the Dnepropetrovsk Sputnik programme.[1] Following the completion of testing it was intercepted and destroyed by Kosmos 397 on 25 February.[2]

Launch
It was launched aboard a Kosmos-3M carrier rocket,[3] from Site 132/1 at the Plesetsk Cosmodrome. The launch occurred at 18:48:48 UTC on 9 February 1971.[4]
Orbit
Kosmos 394 was placed into a low Earth orbit with a perigee of 522 kilometres (324 mi), an apogee of 552 kilometres (343 mi), 65.8 degrees of inclination, and an orbital period of 95.4 minutes.[1] As of 2009, debris from its destruction is still in orbit.[5]
Kosmos 394 was the second of the five original DS-P1-M satellites to be launched, and the first to successfully reach orbit.[1] The three subsequent launches were all successful, before the satellite was replaced with a derivative, Lira.[6] DS-P1-M and Lira satellites were used as targets for the Istrebitel Sputnikov programme.
