The Redeye missile served throughout the 1970's before giving way to the more technologically advanced Stinger missile in 1982. The Stinger is a man-portable, shoulder-fired guided missile system which enables the Marine to effectively engage low-altitude jet, propeller-driven and helicopter aircraft. The system is a "fire-and-forget" weapon employing a passive infrared seeker and proportional navigation system. Stinger also is designed for the threat beyond the 1990s, with an all-aspect engagement capability, and IFF (Identification-Friend-or-Foe), improved range and maneuverability, and significant countermeasures immunity. The missile, packaged within its disposable launch tube, is delivered as a certified round, requiring no field testing or direct support maintenance. The Stinger is launched from a number of platforms: Bradley Stinger Fighting Vehicle, Bradley Linebacker, Avenger (HMMWV), and helicopters as well as Man Portable Air Defense.
