The Mk-46 GWS is a remotely operated naval gun system that uses a 30mm high velocity cannon, a forward looking infrared sensor, a low light television camera, and a laser rangefinder for shipboard self defense against small, high speed surface targets. The Mk-46 GWS includes the Mk-44 Mod.2 30mm cannon, a single barrel, open bolt, dual feed, electrically powered, chain driven automatic cannon. The gun can be operated locally at the gun turret or remotely at the Remote Operating Console in the Combat Information Center (LPD 17 class) or at the Mission Control Center (LCS class).
