The Type95 also had by far the largest warhead of any submarinetorpedo, initially 893 pounds (405 kg), increased to 1210 pounds (550 kg) late in the war.
All Japanese torpedoes made during the war used Japanese Type 97 explosive, a mixture of 60% TNT and 40% hexanitrodiphenylamine.
Most importantly, the Type95 used a simple contact exploder, and was therefore far more reliable than its American counterpart, the Mark 14, until the latter was improved in late-1943.
