Self Defense is performed by which vessels?

• A. Ships with any AD capabilities
• B. Only aircraft
• C. Only submarines
• D. Shore-based artillery

Answer: (A)

Self-defense at sea is carried out by the vessel’s own air-defense capabilities. A ship equipped with AD systems can detect, track, and engage incoming threats—aircraft, missiles, and other guided threats—using its radar, command-and-control, and weapons like missiles or CIWS, along with electronic warfare and decoys. Aircraft can provide protection or support, but they do not replace the ship’s own defense; submarines focus on stealth and other capabilities rather than standard air defense, and shore-based artillery isn’t a practical or reliable defense for a ship away from shore. So, the best answer is that self-defense is performed by ships that have any air-defense capabilities.
