context_page_description: Torpedo nets were a passive ship defensive device against torpedoes. They were in common use from the 1890s until the Second World War. They were superseded by the anti-torpedo bulge and torpedo belts.
context_section_description: The sinking by torpedo of three Allied battleships during the 1915 Dardanelles Campaign, all with torpedo nets deployed, demonstrated that the increased speed of newer torpedoes and the tactic of firing several torpedoes at the same location on the target had made the torpedo net ineffective. Torpedo nets were superseded by the anti-torpedo bulge and torpedo belts.
