Submarine warfare, is normally fought underwater, and it involves using submarines for offensive and defensive naval operations.
They include surveillance, special forces deployment, and attacking enemy vessels. It includes the use of weapons such as torpedoes and missiles, as well as defensive measures like decoys and anti-submarine warfare (ASW) conducted by other submarines, surface ships, and aircraft. Historically, it has also involved strategies like "unrestricted submarine warfare," where submarines attack enemy shipping without warning, as seen in World War I.
