Point-defence (or point-defense; see spelling differences) is the defence of a single object or a limited area, e.g. a ship, building or an airfield, now usually against air attacks and guided missiles. Point-defence weapons have a smaller range in contrast to area-defence systems and are placed near or on the object to be protected. Point-defence may include: * short-ranged interceptor aircraft * Close-in weapon systems on ships * land-based short-ranged anti-aircraft guns or surface-to-air missile systems * Active protection systems on tanks or other armoured fighting vehicles Coastal artillery to protect harbours is similar conceptually, but is generally not classified as point-defence. Similarly, passive systems - electronic countermeasures, decoys, chaff, flares, barrage balloons - are not considered point-defence. == Examples == * Bachem Ba 349 ''Natter'' - vertical take-off rocket powered manned interceptor (prototypes only) * Messerschmitt Me 163 - WWII era German rocket powered interceptor. * Goalkeeper CIWS - Gun CIWS in current service by the Dutch navy. * Kashtan CIWS - Gun-Missile CIWS in current service by the Russian navy. * RIM-116 RAM - Missile CIWS in current use by the US Navy. * Type 730 - in current use by the Chinese Navy. * Arena APS - a Russian point defence system for individual armoured vehicles. * Metal Storm - Another point defence/CIWS system currently in development. 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「Point-defence」の詳細全文を読む スポンサード リンク
