This torpedo, which formed part of HMCS Niobe's armament before the war, is also the type used by early Canadian submarines.

Niobe's armament included this and other torpedoes and the underwater tubes required to launch them. Capable of damaging or sinking ships, the torpedoes complemented Niobe's numerous guns. When Canada acquired two submarines in August 1914, several of Niobe's torpedoes, which would work in the submarines' tubes, were quickly shipped to Esquimalt to arm the new vessels.
