The MK 15 Phalanx Close-In Weapons System (CIWS – pronounced “sea-whiz”) is a rapid-fire, computer-controlled, radar-guided 20-millimeter gun system that can defeat close-in threats.
The system consists of a 20 mm M61 Vulcan 6-barreled Gatling cannon and a Ku band fire control radar system mounted on a swiveling base. It primarily provides fast-reaction terminal defense against low- and high-flying, high-speed maneuvering anti-ship missile (AShM) threats that have penetrated all other defenses.
The Phalanx CIWS system is installed on all U.S. Navy surface combatant ship classes and on those of 24 allied nations.
There is also land based variant of the Phalanx system, called LPWS (Land Phalanx Weapon System). It is used as a C-RAM system to counter incoming rockets, artillery and mortar fire.
