Kosmos 453 (Russian: Космос 453 meaning Cosmos 453), known before launch as DS-P1-Yu No.44, was a Soviet satellite which was launched in 1971 as part of the Dnepropetrovsk Sputnik programme. It was a 325-kilogram (717 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.
Kosmos 453 was successfully launched into low Earth orbit on 19 October 1971, with the rocket lifting off at 12:40:01 UTC. The launch took place from Site 133/1 at the Plesetsk Cosmodrome, and used a Kosmos-2I 63SM carrier rocket.
Kosmos 453 was the forty-sixth of seventy nine DS-P1-Yu satellites to be launched, and the forty-first of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of 266 kilometres (165 mi), an apogee of 471 kilometres (293 mi), 70.9 degrees of inclination, and an orbital period of 91.9 minutes. It remained in orbit until it decayed and reentered the atmosphere on 19 March 1972.
