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

A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 725 from Site 133/1 of the Plesetsk Cosmodrome. The launch occurred at 18:29:56 UTC on 8 April 1975, and resulted in the successfully insertion of the satellite into low Earth orbit. Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1975-026A. The North American Aerospace Defense Command assigned it the catalogue number 07730.

Kosmos 725 was the seventy-sixth of seventy nine DS-P1-Yu satellites to be launched, and the sixty-ninth of seventy two to successfully reach orbit. It was operated in an orbit with a perigee of , an apogee of , 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 6 January 1976.
