Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface ( submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 'tiers' of air defence systems which, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RIM-174 Standard ERAM
The RIM-174 Standard Extended Range Active Missile (ERAM), or Standard Missile 6 (SM-6), is a missile in current production for the United States Navy (USN). It was designed for extended-range anti-air warfare (ER-AAW) purposes, providing capability against fixed and rotary-wing aircraft, unmanned aerial vehicles, anti-ship cruise missiles in flight, both over sea and land, and terminal ballistic missile defense. It can also be used as a high-speed anti-ship missile. The missile uses the airframe of the earlier SM-2ER Block IV (RIM-156, RIM-156A) missile, adding the active radar homing seeker from the AIM-120 AMRAAM, AIM-120C AMRAAM in place of the semi‑active seeker of the previous design. This will improve the capability of the Standard missile against highly agile targets and targets beyond the effective range of the launching vessels' target illumination radars. Initial operating capability was planned for 2013 and was achieved on 27 November 2013. The SM-6 is not meant t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Music hall is a type of British theatrical entertainment that was most popular from the early Victorian era, beginning around 1850, through the World War I, Great War.
