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]

Kosmos 275 was placed into a low Earth orbit with a perigee of 273 kilometres (170 mi), an apogee of 780 kilometres (480 mi), 71 degrees of inclination, and an orbital period of 95.2 minutes.[1] It decayed from orbit on 7 February 1970.[4]

Kosmos 275 was the fifth of nineteen DS-P1-I satellites to be launched.[1] Of these, all reached orbit successfully except the seventh.[5]
