This is a list of satellites which have been given USA designations. 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.

As of 2009-04-06, 203 satellites have received USA designations. For an unknown reason, the designation USA-163 was never assigned.
