Antisubmarine Warfare is the term used to describe what?

• A. Patrols on surface ships to deter other navies.
• B. Air-to-air combat against submarines.
• C. Salvage operations after submarine sinkings.
• D. Techniques, weapons, and equipment used for detection, surveillance, and destruction of enemy submarines.

Answer: (D)

Antisubmarine Warfare centers on locating, tracking, and destroying submarines through a combination of sensors, surveillance methods, and weapons. Detection and surveillance use sonar (both active and passive), sonobuoys, hydrophones, and coordinated patrol aircraft and ships to find submarines. Destruction involves weapons designed for underwater threats, such as depth charges, torpedoes, and anti-submarine missiles, delivered by ships, aircraft, or submarines. The term isn’t about general surface patrols, air-to-air combat against submarines, or salvage after sinkings; it specifically covers the techniques, weapons, and equipment used to detect, monitor, and defeat enemy submarines.
