<P> 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 . </P> <P> As of January 2018, USA designations have been assigned to 280 space missions . Note that there is not always a one - to - one mapping between launch vehicles and mission spacecraft . This can occasionally result in gaps when maintaining records that incorrectly make that assumption, such as the "missing" entries for USA - 163 (which are, symmetrically, contemporary with confusion over "splitting" spacecraft tracks). </P> <Table> <Tr> <Th> Number </Th> <Th> Launch date </Th> <Th> Rocket </Th> <Th> Other designations </Th> <Th> Function </Th> <Th> Status </Th> <Th> Remarks </Th> </Tr> <Tr> <Td> USA - 1 </Td> <Td> 1984 - 06 - 13 </Td> <Td> Atlas E / F </Td> <Td> Navstar - 9 </Td> <Td> Navigation </Td> <Td> Out of service </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 2 </Td> <Td> 1984 - 06 - 25 </Td> <Td> Titan 34D </Td> <Td> KH - 9 </Td> <Td> Reconnaissance </Td> <Td> Deorbited: 1984 - 10 - 18 </Td> <Td> Launched with USA - 3 </Td> </Tr> <Tr> <Td> USA - 3 </Td> <Td> 1984 - 06 - 25 </Td> <Td> Titan 34D </Td> <Td> SSF - D </Td> <Td> ELINT </Td> <Td> Out of service </Td> <Td> Launched with USA - 2 </Td> </Tr> <Tr> <Td> USA - 4 </Td> <Td> 1984 - 08 - 28 </Td> <Td> Titan 34B </Td> <Td> SDS </Td> <Td> Communications </Td> <Td> Out of service </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 5 </Td> <Td> 1984 - 09 - 08 </Td> <Td> Atlas E / F </Td> <Td> Navstar - 10 </Td> <Td> Navigation </Td> <Td> Out of service </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 6 </Td> <Td> 1984 - 12 - 04 </Td> <Td> Titan 34D </Td> <Td> KH - 11 </Td> <Td> Reconnaissance </Td> <Td> Decayed: 1990 - 12 - 31 </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 7 </Td> <Td> 1984 - 12 - 22 </Td> <Td> Titan 34D / Transtage </Td> <Td> DSP - 2 - 6R </Td> <Td> Missile detection </Td> <Td> Retired: 1994 - 12 - 31 </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 8 </Td> <Td> 1985 - 01 - 24 </Td> <Td> Space Shuttle Discovery </Td> <Td> Magnum </Td> <Td> ELINT </Td> <Td> Out of service </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 9 </Td> <Td> 1985 - 02 - 08 </Td> <Td> Titan 34B </Td> <Td> SDS </Td> <Td> Communications </Td> <Td> Out of service </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 10 </Td> <Td> 1985 - 10 - 09 </Td> <Td> Atlas E / F </Td> <Td> Navstar - 11 </Td> <Td> Navigation </Td> <Td> Out of service </Td> <Td> </Td> </Tr> <Tr> <Td> USA - 11 </Td> <Td> 1985 - 10 - 03 </Td> <Td> Space Shuttle Atlantis </Td> <Td> DSCS - III - B4 </Td> <Td> Communications </Td> <Td> Out of service </Td> <Td> Launched with USA - 12 </Td> </Tr> <Tr> <Td> USA - 12 </Td> <Td> 1985 - 10 - 03 </Td> <Td> Space Shuttle Atlantis </Td> <Td> DSCS - III - B5 </Td> <Td> Communications </Td> <Td> Out of service </Td> <Td> Launched with USA - 11 </Td> </Tr> <Tr> <Td> USA - 13 </Td> <Td> 1985 - 12 - 13 </Td> <Td> Scout - G </Td> <Td> ITV - 1 </Td> <Td> Inflatable ASAT target </Td> <Td> Failed .
