What is the role of the Mk 15 Phalanx Close-in Weapon System (CWIS)?

The Mk 15 Phalanx Close-in Weapon System (CWIS) is specifically designed to provide point defense against close-range threats, such as anti-ship missiles and enemy aircraft. It uses radar and a rapid-firing gun to detect, track, and engage incoming threats in a matter of seconds, making it an essential asset for protecting naval vessels from imminent dangers. Its automated system allows for quick response to threats, ensuring that ships can defend themselves in environments where other defense systems may not be effective due to proximity or speed of the threat.

In contrast, options focusing on long-range missile support or surveillance and reconnaissance do not align with the primary function of the Phalanx system. While logistics operations are critical for naval operations, they fall outside the combat and defensive capabilities of the Phalanx. Therefore, the correct answer reflects its intended use in immediate defensive situations against close-in threats to the ship.
