Kosmos 25 (Russian: Космос 25 meaning Cosmos 25), also known as DS-P1 No.4 was a prototype radar target satellite for anti-ballistic missile tests, which was launched by the Soviet Union in 1964 as part of the Dnepropetrovsk Sputnik programme. Its primary mission was to demonstrate the necessary technologies for radar tracking of spacecraft, which would allow future satellites to function as targets.[1]

It was launched aboard a Kosmos-2I 63S1 rocket,[2] from pad 2 of the Mayak Launch Complex at Kapustin Yar. The launch occurred at 13:26 UTC on 27 February 1964.[3]

Kosmos 25 was placed into a low Earth orbit with a perigee of 260 kilometres (160 mi), an apogee of 495 kilometres (308 mi), 49.1 degrees of inclination, and an orbital period of 92.1 minutes.[1] It decayed from orbit on 21 November 1964.[4]

Kosmos 25 was a prototype DS-P1 satellite, the last of four to be launched.[1] Of these, it was the third to successfully reach orbit after Kosmos 6 and Kosmos 19.[5] It was succeeded by the first operational DS-P1 satellite, Kosmos 36.
