A torpedo developed by the Japanese. It was nicknamed the "Long Lance" and it lived up to its name. While other torpedoes used steam propulsion for their torpedoes, the Japanese came up with the concept of using pure, compressed oxygen to propel their torpedoes. Advantages of oxygen propulsion were no wake, longer range, and typically faster speed than the steam-propelled ones. These were used to devastating effect during the sea battles of Guadalcanal. With the combination of both speed and damage, these torpedoes were some of the few naval weapons that allowed small ships like destroyers to heavily damage or even sink a battleship.

Although they achieved an unthinkable range of 40 km with their heavy warheads - almost triple that of the 14km maximum range of the Allied 21 inch Mark 15 torpedoes - using pure, compressed oxygen is so dangerous that some IJN ships were sunk because of their oxygen torpedoes exploding. Examples include Chikuma and Choukai which both received mild damage from enemy ships that detonated the oxygen torpedoes in the hold.
