Phalanx Close-in weapon system takes out air and surface threats.

Phalanx Block 1B, the latest upgrade, with its surface mode configuration, augments the proven anti-air warfare capability by adding a forward looking infrared sensor and optimized gun barrels to the Block 1A configuration. It allows Phalanx to be used against littoral warfare threats such as helicopters and high-speed surface threats. Block 1B also adds new control stations with situational awareness that allows operators to visually track and identify targets before engagement.

Phalanx is installed on all U.S. Navy surface combatant ship classes and on those of 24 allied nations.
