Spaag




A self-propelled anti-aircraft weapon (SPAA, also ''self-propelled air defense'', SPAD) is an Anti-aircraft gun or missile mounted on a vehicle Chassis .

Specific weapon systems include Machine Gun s, Autocannon , larger guns, or Missile s, and some mount both guns and longer-ranged missiles. The vehicle mount may be based on a Truck . Weapons meant for deployment in the forward battle area may be mounted on Armoured Fighting Vehicles , such as an APC or Tank , for protection from aircraft, artillery, and small arms fire.

Anti-aircraft guns are usually mounted in a quickly-traversing Turret with a high range of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. The concept was pioneered mainly by Germany during World War II , with their Flakpanzer series. Today, Missile s have largely replaced medium and heavy antiaircraft guns.

The Russian equivalent of ''SPAAG'' is ''ZSU'', for ''zenitnaya samokhodnaya ustanovka'', ("anti-aircraft self-propelled mount").
