What is a CIWS and its purpose?

• A. A Long-range radar system used for detection at sea.
• B. A Close-In Weapons System designed to defend a ship from incoming missiles and aircraft at close range.
• C. A system for anchor handling.
• D. A life raft deployment mechanism.

Answer: (B)

A CIWS is a Close-In Weapons System, and its purpose is to provide the ship with a final, close-range defense against threats like missiles and aircraft. It combines a high-rate-of-fire gun with radar and electro-optical tracking to automatically detect, track, and engage incoming targets that have penetrated longer-range defenses. When a threat is within its effective envelope, the system fires rapidly to create a wall of projectiles in front of the target, aiming to destroy or disrupt the threat before it can strike the vessel. This makes it the last line of defense at short range, not a long-range radar, an anchor-handling setup, or a life-raft deployment mechanism.
