Kosmos 265 ( Russian : Космос 265 meaning Cosmos 265 ), known before launch as DS-P1-Yu No.21 , was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles . It was built by the Yuzhnoye Design Bureau , and launched in 1969 as part of the Dnepropetrovsk Sputnik programme. ^[1] It had a mass of 325 kg (717 lb). ^[1]

Kosmos 265 was launched from Plesetsk Cosmodrome Site 133/1, ^[2] atop a Kosmos-2I 63SM carrier rocket . The launch occurred on 7 February 1969 at 13:59 UTC, and resulted in Kosmos 265's successful deployment into low Earth orbit . ^[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-012A.

Kosmos 265 was operated in an orbit with a perigee of 261 kilometres (162 mi), an apogee of 413 kilometres (257 mi), 70.9 degrees of inclination , and an orbital period of 91.3 minutes. ^[1]^[4] It remained in orbit until it decayed and reentered the atmosphere on 1 May 1969. ^[4] It was the eighteenth of seventy nine DS-P1-Yu satellites to be launched, ^[1] and the seventeenth of seventy two to successfully reach orbit. ^[5]
