The Close-In Weapon System (CIWS) is among the standard armaments in Gundam series. It is mostly used for point-defense and to intercept missiles fired at the target. The standard CIWS in Gundam are various vulcan guns, usually mounted in a Mobile Suit's head, which allows it to track targets. Many battleships are also armed with CIWS. Some Universal Century Space Vessels, such as the battleship Albion, use laser turrets instead of the typical gatling guns as CIWS.
In the Cosmic Era, CIWS are a common weapon found on warships and mobile suits, the most common is the 75mm Igelstellung.
