List of USA satellites

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This is a list of satellites and spacecraft which have been given USA designations by the United States Air Force. These designations have been applied to most US military satellites since 1984, and replaced the earlier OPS designation. It is comparable to the Soviet/Russian Kosmos designation.

USA designations have been assigned to 246 space missions. For an unknown reason, the designation USA-163 has never been assigned.[1]
