What is the primary function of the Phalanx CIWS?

The primary function of the Phalanx Close-In Weapon System (CIWS) is to provide automated close-in defense against incoming threats. This system is designed as a last line of defense for naval vessels, capable of detecting and intercepting anti-ship missiles, airborne threats, and small fast boats that may pose a danger to the ship.

The Phalanx CIWS utilizes a radar-guided 20mm Gatling gun that can fire at a very high rate, allowing it to react quickly to fast-moving targets trying to approach the ship. Its automated nature means that once it acquires a target, it can engage without requiring continual input from naval personnel, which is critical in high-stress combat situations where decisions must be made rapidly.

Understanding the specific role of the Phalanx CIWS helps to appreciate its significance in naval warfare, highlighting the need for rapid and reliable defense mechanisms on modern warships.
