The meaning of «fim-92 stinger»

The FIM-92 Stinger is a man-portable air-defense system (MANPADS) that operates as an infrared homing surface-to-air missile (SAM). It can be adapted to fire from a wide variety of ground vehicles and helicopters (Air to Air Stinger). Developed in the United States, it entered service in 1981 and is used by the militaries of the United States and 29 other countries. It is principally manufactured by Raytheon Missile Systems and is produced under license by EADS in Germany and by ROKETSAN in Turkey, with 70,000 missiles produced.

Light to carry and easy to operate, the FIM-92 Stinger is a passive surface-to-air missile that can be shoulder-fired by a single operator (although standard military procedure calls for two operators, team chief and gunner). The FIM-92B missile can also be fired from the M-1097 Avenger and the M6 Linebacker. The missile is also capable of being deployed from a Humvee Stinger rack, and can be used by airborne troops. A helicopter launched version exists called Air-to-Air Stinger (ATAS).

The missile is 5.0 ft (1.52 m) long and 2.8 in (70 mm) in diameter with 3.9 in (100 mm) fins. The missile itself weighs 22 lb (10.1 kg), while the missile with its launch tube and integral sight, fitted with a gripstock and Identification friend or foe (IFF) antenna, weighs approximately 34 lb (15.2 kg). It has a targeting range of up to 4,800 m and can engage low altitude enemy threats at up to 3,800 m. The Stinger is launched by a small ejection motor that pushes it a safe distance from the operator before engaging the main two-stage solid-fuel sustainer, which accelerates it to a maximum speed of Mach 2.54 (750 m/s). The warhead contains 1.02 kg (2.25 lb) of HTA-3[3] (a mix of HMX, TNT, and aluminum powder) explosive with an impact fuze and a self-destruct timer that functions 17 seconds after launch.

To fire the missile, a BCU (Battery Coolant Unit) is inserted into the gripstock. This device consists of a supply of high-pressure gaseous argon which is injected into the seeker to cryogenically cool it to operating temperature, and a thermal battery which provides power for target acquisition: a single BCU provides power and coolant for roughly 45 seconds, after which another must be inserted if the missile has not been fired. The BCUs are somewhat sensitive to abuse, and have a limited shelf life due to argon leakage. The IFF system receives power from a rechargeable battery which is part of the IFF interrogator box which plugs into the base of the gripstock's pistol grip. Guidance to the target is initially through proportional navigation, then switches to another mode that directs the missile towards the target airframe instead of its exhaust plume.

There are three main variants in use: the Stinger basic, STINGER-Passive Optical Seeker Technique (POST), and STINGER-Reprogrammable Microprocessor (RMP). These correspond to the FIM-92A, FIM-92B, and FIM-92C and later variants respectively.
