Armament

Asatsuyu (朝露) ("Morning dew") was one of 32 Kamikaze-class destroyers built for the Imperial Japanese Navy (IJN) in the first decade of the 20th century.

Design and description

The Kamikaze-class destroyers were improved versions of the preceding Harusame class.[1] They displaced 381 long tons (387 t) at normal load and 450 long tons (460 t) at deep load. The ships had a length between perpendiculars of 227 feet (69.2 m) and an overall length of 234 feet (71.3 m), a beam of 21 feet 7 inches (6.6 m) and a draught of 6 feet (1.8 m). The Kamikazes were powered by two vertical triple-expansion steam engines, each driving one shaft using steam produced by four Kampon water-tube boilers. The engines produced a total of 6,000 indicated horsepower (4,500 kW) that gave the ships a maximum speed of 29 knots (54 km/h; 33 mph). They carried a maximum of 100 long tons (102 t) of coal[2] which gave them a range of 1,500 nautical miles (2,800 km; 1,700 mi) at a speed of 15 knots (28 km/h; 17 mph). Their crew consisted of 70 officers and ratings.[3]

The main armament of the Kamikaze-class ships consisted of two 40-calibre quick-firing (QF) three-inch (76 mm) 12 cwt guns[Note 1] on single mounts; the forward gun was located on superstructure, but the aft gun was at the stern. Four 28-calibre QF three-inch 8 cwt guns on single mounts were positioned abreast the superstructure, two in each broadside. The ships were also armed with two single rotating mounts[1][3] for 450-millimetre (17.7 in)[4] torpedoes between the superstructure and the stern gun.[1]

Construction and career

Asatsuyu was launched at the Osaka Iron Works's shipyard in Osaka on 2 April 1906[1] and completed on 16 October. The ship ran aground on a reef in Nanao Bay, Japan, on 9 November 1913. The wreck broke apart on the 30 November 1913 and Asatsuyu was stricken from the navy list on 15 April 1914.[5]

Notes

  1. ^ "Cwt" is the abbreviation for hundredweight, 12 cwt referring to the weight of the gun.
