USA-180 was launched at 05:39:00 UTC on 6 November 2004, atop a Delta II carrier rocket, flight number D308, flying in the 7925-9.5 configuration.[3] The launch took place from Space Launch Complex 17B at the Cape Canaveral Air Force Station,[5] and placed USA-180 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37FM apogee motor.[2]

By 5 January 2005, USA-180 was in an orbit with a perigee of 19,936 kilometres (12,388 mi), an apogee of 20,426 kilometres (12,692 mi), a period of 717.94 minutes, and 54.8 degrees of inclination to the equator.[4] It is used to broadcast the PRN 02 signal, and operates in slot 1 of plane D of the GPS constellation. The satellite has a mass of 2,032 kilograms (4,480 lb), and a design life of 10 years.[2] As of 2019 it remains in service.
