What is the ultimate defense system against submarines?
Short answerEverything working together: layered sensors and weapons whose information is fused into a coherent defense.
NotesASW depends on a system of systems. Sensors at different scales find and classify contacts, weapons cover different engagement ranges, and commanders combine their data. Like air defense, ASW works through overlapping layers rather than a single decisive device. A supposed golden weapon rarely makes an entire opposing system irrelevant because adaptation occurs across platforms, sensors, doctrine, and organization.
