Phalanx Close-In Weapon System
Last Line of Defense for air, land and sea
At sea, the Phalanx® Close-In Weapon System—a rapid-fire, computer-controlled, radar-guided gun system—is designed to defeat anti-ship missiles and other close-in air and surface threats. The Land-based Phalanx Weapon System is part of the U.S. Army's Counter Rocket, Artillery and Mortar systems used to detect and destroy incoming rounds in the air before they hit their ground targets. It also helps provide early warning of attacks.
A self-contained package, Phalanx automatically carries out functions usually performed by multiple systems: search, detection, threat evaluation, tracking, engagement and kill assessment. The Block 1B version of Phalanx adds control stations that allow operators to visually track and identify targets before engagement.
Phalanx 1B's configuration augments the system's proven anti-air warfare capability by adding a forward looking infrared sensor. It allows Phalanx to be used against helicopters and high-speed surface craft at sea while the land-based version helps identify and confirm incoming dangers.
Phalanx is installed on all U.S. Navy surface combatant ship classes and on those of 24 allied nations. The land-based version is forward deployed and has been used in combat.
