The Phalanx Close In Weapons System (CIWS) is an anti-Anti-ship missile system that was designed and manufactured by the General Dynamics Corporation, Pomona Division.[6], now Raytheon. Used by the United States Navy on every class of surface combat ship and by the United States Coast Guard aboard its Hamilton and Legend class cutters, it is also used by navies of 23 allied nations.[citation needed] Because of their distinctive barrel-shaped radome and their automated nature of operation, Phalanx CIWS units are sometimes nicknamed "R2-D2" in the US Navy, after the famous droid from Star Wars,[8] and as Daleks in the Royal Navy, after the aliens from Doctor Who. The basis of the system is the 20 mm M61 Vulcan Gatling gun autocannon, used since the 1960s by the United States military in nearly all fighter aircraft (and one land mounting, the M163 VADS), linked to a Ku-band radar system for acquiring and tracking targets. This proven system was combined with a purpose-made mounting, capable of fast elevation and traverse speeds, to track incoming targets. An entirely self-contained unit, the mounting houses the gun, an automated fire control system and all other major components, enabling it to automatically search for, detect, track, engage and confirm kills using its computer-controlled radar system. Due to this self-contained nature, Phalanx is ideal for support ships which lack integrated targeting systems and generally have limited sensors. The entire unit has a mass between 5,500 and 6,100 kg (12,400 to 13,500 lb). On February 25, 1991, during the first Gulf War, the Phalanx-equipped USS Jarrett (FFG-33) was a few miles from the USS Missouri (BB-63) and the British destroyer HMS Gloucester (D96). The ships were attacked by an Iraqi Silkworm missile (often referred to as the Seersucker), at which Missouri fired its SRBOC chaff. The Phalanx system on Jarrett, operating in the automatic target-acquisition mode, fixed upon Missouri's chaff, releasing a burst of rounds. From this burst, four rounds hit Missouri which was two to three miles (about 5 km) from Jarrett at the time. There were no injuries. [READ THE REST OF THIS ARTICLE]
