The Phalanx Close-In Weapon System (CIWS) is a highly effective ship-mounted gun system designed for close-range defense against a variety of threats, including anti-ship missiles, aircraft, and small surface craft. Developed by Raytheon, the Phalanx CIWS is characterized by its rapid-fire M61 Vulcan Gatling gun, which can unleash a hail of 20mm projectiles at an astonishing rate of over 4,000 rounds per minute. The system is integrated with advanced radar and electro-optical sensors, enabling it to detect, track, and engage multiple targets autonomously. In response to incoming threats, the Phalanx CIWS delivers a storm of high-velocity projectiles, effectively intercepting and neutralizing potential dangers before they reach the ship. This automated and highly accurate defense system has become a crucial element in the layered protection of naval vessels, enhancing their survivability and the safety of the crew.
