Japanese destroyer Hatsushimo (1905)

Hatsushimo (初霜) ("First frost" or "October) was one of 32 Kamikaze-class destroyer (1905) 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 destroyer. They displaced 381 LT at normal load and 450 LT at deep load. The ships had a length between perpendiculars of 227 ft and an overall length of 234 ft, a beam of 21 ft and a draught of 6 ft. 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 6000 ihp that gave the ships a maximum speed of 29 kn. They carried a maximum of 100 LT of coal which gave them a range of 1500 nmi at a speed of 15 kn. Their crew consisted of 70 officers and ratings.

The main armament of the Kamikaze-class ships consisted of two 40-calibre quick-firing (QF) 3 in 12 cwt guns 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 for 450 mm torpedoes between the superstructure and the stern gun. When Hatsushimo was converted into a minesweeper in 1924, she was rearmed with a pair of 12 cm 3rd Year Type guns taken from older ships on single mounts and the three-inch 8 cwt guns were removed.

Construction and career
Hatsushimo was launched at the Yokosuka Naval Arsenal on 13 May 1905 and completed on 18 August. The ship saw service in World War I and participated in the Siberian Expedition. She was converted into a minesweeper on 1 December 1924. Hatsushimo was decommissioned on 1 April 1928, although she remained in use until 12 October and was subsequently broken up for scrap.
