Kosmos 275 (Russian: Космос 275 meaning Cosmos 275), also known as DS-P1-I No.5 was a satellite which was used as a radar target for anti-ballistic missile tests. It was launched by the Soviet Union in 1969 as part of the Dnepropetrovsk Sputnik programme.[1]

It was launched aboard a Kosmos-2I 63SM rocket,[2] from Site 133/1 at Plesetsk. The launch occurred at 16:00:08 UTC on 28 March 1969.[3]
