Torpedo defence includes evasive maneuvers, passive defense like
torpedo belt
The torpedo belt was part of the armoring scheme in some warships between the 1920s and 1940s. It consisted of a series of lightly armored compartments, extending laterally along a narrow belt that intersected the ship's waterline. In theory thi ...

torpedo bulges, and sonar torpedo sensors, "soft-kill" active countermeasures like
sonar decoy
A sonar decoy is a device for decoying sonar. One may be released from a submarine or a surface vessel. A decoy acts as false targets for human operators and/or sonar-homing weapons such as acoustic torpedoes. Many count as a type of torpedo defenc ...
