The 9K34 Strela-3 ((ロシア語:9К34 «Стрела-3»); (英語:arrow)) man-portable air defence missile system (MANPADS) was developed in the Soviet Union as a response to the poor performance of the earlier 9K32 Strela 2 (SA-7 Grail) system. "9K34" is its GRAU designation and its NATO reporting name is SA-14 Gremlin. The missile was largely based on the earlier Strela 2, and thus development proceeded rapidly. The new weapon was accepted to service in the Soviet Army in January 1974. ==Description== The most significant change over the Strela 2 was the introduction of an all-new infra-red homing seeker head. The new seeker worked on FM modulation (con-scan) principle, which is less vulnerable to jamming and decoy flares than the earlier AM (spin-scan) seekers, which were easily fooled by flares and even the most primitive infrared jammers. Most importantly, the new seeker also introduced detector element cooling in the form of a pressurized nitrogen bottle attached to the launcher. The effect of cooling was to expand the seeker's lead sulphide detector element's sensitivity range to longer wavelengths (slightly over 4 µm as opposed to 2.8 µm of uncooled PbS elements). In practice this made possible the tracking of cooler targets over longer ranges, and enabled forward-hemisphere engagement of jets under favourable circumstances.The seeker also had better tracking rate, enabling the missile to track maneuvering of fast and approaching targets. A negative side effect from the aforementioned improvements was increased missile weight, which caused a slight decrease in the kinematic performance of the original Strela-2 (SA-7). Against relatively slow, low-altitude battlefield air threats the overall effectiveness was much improved. Strela-3 missiles have been exported to over 30 countries. The original Strela-3 missile was the 9M36. The follow-on to the Strela-3 was Igla. The naval version of this missile has the NATO reporting name of SA-N-8. 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「9K34 Strela-3」の詳細全文を読む スポンサード リンク
