Undersea warfare refers to military operations conducted beneath the ocean's surface. It involves the use of submarines, underwater drones, and other technologies to detect, track, and engage enemy vessels. Key components include anti-submarine warfare (ASW) and submarine warfare, which aim to protect naval assets and disrupt enemy operations. Naval forces employ various tools for undersea warfare, such as sonar systems and torpedoes. NATO and other military alliances often conduct joint exercises to enhance their capabilities in this domain. The strategic importance of undersea warfare has grown with advancements in technology and the increasing complexity of maritime threats.
