Shimakaze (島風) (Island Wind) was a one-off super-destroyer built for the Imperial Japanese Navy during World War II. She was armed with six 127 mm (5.0 in) dual purpose guns and conventional anti-aircraft and anti-submarine weaponry. More importantly, she was the only Japanese destroyer to be armed with 15 torpedo tubes each capable of firing the deadly 610 mm (24 in) Type 93 "Long Lance" torpedo. The ship was a testbed for an enormously-powerful, high-temperature, high-pressure steam engine that was able to develop nearly 80,000 shp (60,000 kW). This made her one of the fastest destroyers in the world: her designed speed was 39 kn (72 km/h; 45 mph), but on trials she made 40.9 kn (75.7 km/h; 47.1 mph).
