Quick Summary

The Redeye was an early surface-to-air infrared homing missile developed by the United States. It was designed to be shoulder-fired by individual soldiers, making it a man-portable air-defense system (MANPADS). The Redeye's primary function was to counter low-flying aircraft, particularly helicopters and ground-attack planes, by seeking the heat emitted from their engines.12

While effective for its time, the Redeye had limitations, including a relatively short range and susceptibility to countermeasures like flares. It was eventually replaced by more advanced systems like the Stinger missile, which offered improved performance and countermeasures.12
