It was a {{convert|400|kg|adj=on}} spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1] A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 745 from Site 133/1 of the Plesetsk Cosmodrome.[2] The launch occurred at 12:05 UTC on 24 June 1975, and resulted in the successfully insertion of the satellite into low Earth orbit.[3] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1975-058A.[4] The North American Aerospace Defense Command assigned it the catalogue number 07982. Kosmos 745 was the seventy-seventh of seventy nine DS-P1-Yu satellites to be launched,[1] and the seventieth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of {{convert|260|km}}, an apogee of {{convert|499|km}}, 70.9 degrees of inclination, and an orbital period of 92.1 minutes.[7] It remained in orbit until it decayed and reentered the atmosphere on 12 March 1976.[6] See also{{Portal|Spaceflight}}
