USA-5 was launched at 21:41 UTC on 8 September 1984, atop an Atlas E/F carrier rocket with an SGS-2 upper stage. The Atlas used had the serial number 14E, and was originally built as an Atlas E.[3] The launch took place from Space Launch Complex 3W at Vandenberg Air Force Base,[5] and placed USA-5 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-27 apogee motor.[2]
By 8 October 1984, USA-5 had been raised to an orbit with a perigee of 19,961 kilometres (12,403 mi), an apogee of 20,404 kilometres (12,678 mi), a period of 717.98 minutes, and 63.2 degrees of inclination to the equator.[4] The satellite had a design life of 5 years and a mass of 758 kilograms (1,671 lb).[2] It broadcast the PRN 12 signal in the GPS demonstration constellation, and was retired from service on 26 March 1996. It was the last Block I satellite to be decommissioned.
