The General Dynamics FIM-43 Redeye was a man-portable surface-to-air missile system. It used infrared homing to track its target. Production was terminated in September 1969 after about 85,000 rounds had been built - in anticipation of the Redeye II, that would later become the FIM-92 Stinger. The Redeye was withdrawn gradually between 1982 and 1995 as the Stinger was deployed.
The missile is fired from the M171 missile launcher. First the seeker is cooled to operating temperature, the operator then begins visually tracking the target - using the sight unit on the launcher. Once the target is locked onto by the missile a buzzer in the launcher hand grip begins vibrating, alerting the operator. The operator then presses the trigger, which fires the initial booster stage and launches the missile out of the tube at a speed of around 80 feet per second (25 m/s). As the missile leaves the tube spring-loaded fins pop out, 4 stabilizing tail fins at the back of the missile, and two control surfaces at the front of the missile. Once the missile has traveled six meters, the sustainer motor ignites. The sustainer motor takes the missile to its peak velocity of Mach 1.7 in 5.8 seconds. 1.25 seconds after the sustainer is ignited, the warhead is armed.
The missile\'s seeker is only capable of tracking the hot exhausts of aircraft, which limits the engagements to tail-chase only. The missile\'s blast fragmentation warhead is triggered by an impact fuze requiring a direct hit. As a first generation missile it is susceptible to a variety of countermeasures including flares and hot brick jammers. In addition, its inability to manoeuver at a rate greater than 3 G means that it can be simply out turned if it is spotted.
Redeye missiles were delivered to the Mujahideen by the US during the Soviet invasion of Afghanistan in 1984, where they were used to shoot down a number of aircraft including several Su-25 jets as well as Mi-24 and Mi-8 helicopters. By November 1985 it had largely been replaced by the dramatically more successful FIM-92 Stinger missiles.
The Redeye was known as Hamlet in Danish service.
