The Harusame-class destroyers (春雨型駆逐艦, Harusamegata kuchikukan) was a class of seven torpedo boat destroyers (TBDs) of the Imperial Japanese Navy. The Harusame class of destroyers were the first destroyers to be built in Japan.

Background

The Harusame-class destroyers were part of the 1894 Imperial Japanese Navy ten-year expansion and modernization plan for based on lessons learned in the First Sino-Japanese War. In the second phase of this plan, from fiscal 1897, after 12 destroyers had been imported from the United Kingdom, budget cutbacks reduced the number of new vessels to only four more (two each from the Akatsuki and Shirakumo classes).

In fiscal year 1900, the Imperial Japanese Navy decided to cancel plans for a torpedo boat tender, which freed funds to purchase four additional destroyers. Likewise, in fiscal 1903, the cancellation of six planned utility vessels freed funds to produce an additional three destroyers.

In order to cut costs and to help develop the Japanese shipbuilding industry, it was decided to construct all seven of the new destroyers at Japanese yards. The first four were built at the Yokosuka Naval Arsenal, and the remaining three at the Kure Naval Arsenal.

Design

The Harusame-class ships attempted to incorporate the best features of the existing destroyer designs in the Navy's inventory. The bow design and front half of the vessel was substantially identical to the previous Yarrow-built Ikazuchi class, whereas the aft section was a copy of the previous Thornycroft-built Murakumo class.

Externally, the design retained the four-smokestacks of the Ikazuchi class, and the improved rudder design of the Akitsuki class. The main design issue was with the coal-fired triple expansion steam engines, which copied the design of the Yarrow water-tube boilers. As with the Ikazuchi class, the rated power was 7,000 shaft horsepower (5,200 kW); however, problems with quality of the materials and construction meant that actual maximum power was considerably less.

Armament was the similar to the previous Ikazuchi and Murakumo classes; i.e. two QF 12-pounder on a bandstand on the forecastle, four QF 6-pounder Hotchkiss (two sided abreast the conning tower, and two sided between the funnels and two single tubes for 18 in (460 mm) torpedoes.

Operational history

All of the Harusame-class destroyers were completed in time to be used in combat during the Russo-Japanese War of 1904-1905, with the final three vessels completed just in time to take part in the crucial final Battle of Tsushima. Hayatori was lost after striking a naval mine during the conflict off of Port Arthur 38°47′S 121°30′E.

Harusame was lost in 1911 after running aground in Matoya Bay in Mie Prefecture, Japan 34°25′N 137°00′E. On 28 August 1912, the remaining five vessels were derated to third-class destroyers and were removed from front line combat service. However, all five served again during World War I, albeit in minor roles.

All five surviving vessels were converted to auxiliary minesweepers on 1 April 1922, but were used for only a year until converted to unarmed utility vessels, and were then subsequently scrapped in 1924 or 1926.
