Anti-submarine net

An anti-submarine net or anti-submarine boom is a boom placed across the mouth of a harbour or a strait for protection against submarines. Net laying ships would be used to place and remove the nets. The US Navy used anti-submarine net in the Pacific War to protect major US Naval Advance Bases. Some Net cutter submarines were used in the war. [1][2][3]
