Ginocchio towed torpedo
Weapon
The Ginocchio towed torpedo was based on an Italian concept of World War I and consisted of a towed torpedo that was streamed over the stern near a submarine contact in the hope that it would strike the submarine, triggering its warhead. Depth-keeping proved to be a problem during sea trials and it does not appear to have ever been operationally used.
