It was a 250 kg spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.

Launch
Kosmos 472 was successfully launched into low Earth orbit on 25 January 1972, with the rocket lifting off at 11:15:01 UTC. The launch took place from Site 133/1 at the Plesetsk Cosmodrome, and used a Kosmos-2I 63SM carrier rocket.

Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1972-004A. The North American Aerospace Defense Command assigned it the catalogue number 05804.

Kosmos 472 was the fiftieth of seventy nine DS-P1-Yu satellites to be launched, and the forty-fifth of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of 195 km, an apogee of 1417 km, 81.9 degrees of inclination, and an orbital period of 101 minutes. It remained in orbit until it decayed and reentered the atmosphere on 18 August 1972.
