Type 95 torpedo

The Type 95 torpedo was a submarine-launched torpedo of the Imperial Japanese Navy in World War II, developed from the Type 93 Long Lance and fired from a standard 533 mm torpedo tube of a submerged submarine. The first model carried a 405 kg warhead and the second a 550 kg warhead, compared with 490 kg for the Type 93. Range for the first model was 9,000 m at 49 to 51 knots or 12,000 m at 45 to 47 knots, about three times the range of the US Navy Mark 14 at the same speed. The article calls it the fastest torpedo in common use by any navy during the war, with the largest warhead of any submarine torpedo. Its engine was a kerosene-oxygen wet-heater rather than the compressed air used by most torpedoes of the time.
