Torpedo Defense Systems


Torpedo defence includes evasive maneuvers, passive defense like torpedo belts, torpedo nets, torpedo bulges and active defenses, like anti-torpedo torpedoes similar in idea to missile defense systems.

Torpedo nets were a passive ship defensive device against torpedoes. They were in common use from the 1890s until WW2. They were superseded by the anti-torpedo bulge and torpedo belts.

The anti-torpedo bulge (also known as an anti-torpedo blister) is a form of defence against naval torpedoes occasionally employed in warship construction in the period between WW1 and WW2. It involved fitting (or retrofitting) partially water-filled compartmentalized sponsons on either side of a ship's hull, intended to detonate torpedoes, absorb their explosions, and contain flooding to damaged areas within the bulges.

The torpedo belt was part of the armouring scheme in some warships between the 1920s and 1940s. It consisted of a series of lightly armoured compartments, extending laterally along a narrow belt that intersected the ship's waterline. In theory this belt would absorb the explosions from torpedoes, or any naval artillery shells that struck below the waterline, and thus minimize internal damage to the ship itself.

Torpedo belts are also known as Side Protection Systems or SPS, or Torpedo Defense System or TDS.
