Submarines are once again being recognized as a key factor in maintaining a powerful military. Historically it has proved impossible for a country to keep global military status, without dominance at sea. Since World War I, it has also been impossible for surface ships to hold dominance at sea, without the use of submarines. In fact, today the use of submarines is not only pivotal to naval campaigns, but with their growing cruise and ballistic missile capabilities, subs are also an important part of any major land offensive.
Even before a conflict arises, a submarine’s ability to deploy military strength to an area without being detected is strategically invaluable. Conversely then, the ability to neutralize an opponent’s underwater force must be a primary objective. As submarines become more pivotal to military success, never before has Anti-Submarine Warfare (ASW) been more important.
