Last line of defense
The Phalanx® weapon system is a rapid-fire, computer-controlled, radar-guided gun that can defeat anti-ship missiles and other close-in threats on land and at sea.
Double duty
At sea, navies use the Phalanx weapon system to defeat anti-ship missiles and close-in threats that have pierced other lines of defense. On land, the U.S. Army uses it to detect and counter rocket, artillery and mortar systems.
Multifunctional
The Phalanx weapon system carries out functions usually performed by multiple systems: search, detection, threat evaluation, tracking, engagement and kill assessment.
The Block 1B version adds control stations that allow operators to visually track and identify targets before engagement. With an added forward-looking infrared sensor, the 1B variant can be used at sea against helicopters and high-speed surface craft and on land to help identify and confirm incoming threats.
The Phalanx weapon system 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.
The Phalanx close-in weapon system stopped a Houthi cruise missile that was within seconds of impacting U.S. Navy ship USS Gravely, saving more than 300 sailors onboard. Raytheon employees working on the Phalanx program share what that first-ever at-sea engagement meant to them.
