Hayabusa-class torpedo boat

The Hayabusa-class torpedo boats were constructed for the Imperial Japanese Navy as part of the ten-year naval expansion program. They were completed between 1900 and 1904.

All of the vessels served in the Russo-Japanese war, the Kiji being mined off Port Arthur, though a new Kiji was built as a replacement. They were notable for their attacks on the Russian fleet on the night of 27/28 May 1905 during the Battle of Tsushima, expending a large number of torpedoes. They were able to inflict significant damage on a number of Russian ships, that were scuttled or sunk the next day.

After serving in World War I, all remaining fifteen vessels were decommissioned between 1919 and 1923, some were scrapped, others turned into auxiliaries.
