FIM-92 Stinger is a shoulder fired missile that uses passive infrared to track the target. It was first started in in 1967 as the Redeye II. It was accepted for further development by the U.S. Army in 1971 and designated FIM-92; the Stinger appellation was chosen in 1972. Because of technical difficulties that dogged testing, the first shoulder launch was not until mid-1975. Production of the FIM-92A began in 1978 to replace the FIM-43 Redeye. FIM-92C has reprogrammable electronics system to allow for upgrades along with the dual-detector seeker which allowed more resistance to countermeasures.
AIM-92 are the air launch version of the missile for use on helicopters.
Stingers were first used in conflict by SAS during the Falklands War which used it to shoot down a Argentine Pucará ground attack aircraft along with Aerospatiale SA-330 Puma helicopter.
