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 (as an AAM). Developed in the United States this weapon system entered service in 1981 and is used by the militaries of the United States and by 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. ==Description== 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, spotter 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 long and in diameter with 10 cm fins. The missile itself weighs , while the missile with launcher weighs approximately . 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 is a 3 kg penetrating hit-to-kill warhead type with an impact fuze and a self-destruct timer. To fire the missile, a BCU (Battery Coolant Unit) is inserted into the handguard. This shoots a stream of argon gas into the system, as well as a chemical energy charge that enables the acquisition indicators and missile to get power. The batteries are somewhat sensitive to abuse, with a limited amount of gas. Over time, and without proper maintenance, they can become unserviceable. The IFF system receives power from a rechargeable battery. 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. The POST has a dual-detector seeker: IR and UV. This allows it to distinguish targets from countermeasures much better than the Redeye and FIM-92A, which have IR-only. While modern flares can have an IR signature that is closely matched to the launching aircraft's engine exhaust, there is a readily distinguishable difference in UV signature between flares and jet engines.〔(【引用サイトリンク】title=FIM-92A Stinger Weapons System: RMP & Basic )〕 The Stinger-RMP is so-called because of its ability to load a new set of software via ROM chip inserted in the grip at the depot. If this download to the missile fails during power-up, basic functionality runs off the on-board ROM. The four-processor RMP has 4 KB of RAM for each processor. Since the downloaded code runs from RAM, there is little space to spare, particularly for processors dedicated to seeker input processing and target analysis. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「FIM-92 Stinger」の詳細全文を読む スポンサード リンク
