Japanese destroyer Sumire (1944)

Sumire (菫) was one of 23 escort destroyers of the Tachibana sub-class of the Matsu-class destroyer built for the Imperial Japanese Navy during the final stages of World War II. Completed in March 1945, she saw no combat during the war and was used to repatriate Japanese personnel after the war until 1947. Mid-year the destroyer was turned over to Great Britain and subsequently sunk as a target.

Design and description
The Tachibana sub-class was a simplified version of the preceding Matsu-class destroyer to make them even more suited for mass production. The ships measured 100 m long overall, with a beam of 9.35 m and a draft of 3.37 m. They displaced 1309 t at standard load and 1554 t at deep load. The ships had two Kampon geared steam turbines, each driving one propeller shaft, using steam provided by two Kampon water-tube boilers. The turbines were rated at a total of 19000 shp for a speed of 27.8 kn. The Tachibanas had a range of 4680 nmi at 16 kn.

The main armament of the Tachibana sub-class consisted of three Type 89 127 mm dual-purpose guns in one twin-gun mount aft and one single mount forward of the superstructure. The single mount was partially protected against spray by a gun shield. The accuracy of the Type 89 guns was severely reduced against aircraft because no high-angle gunnery director was fitted. They carried a total of 25 Type 96 25 mm anti-aircraft guns in 4 triple and 13 single mounts. The Tachibanas were equipped with Type 13 early-warning and Type 22 surface-search radars. The ships were also armed with a single rotating quadruple mount amidships for 610 mm torpedoes. They could deliver their 60 depth charges via two stern rails and two throwers.

Construction and service
Sumire (Violet) was ordered in Fiscal Year 1943 under the Modified 5th Naval Armaments Supplement Program as part of the Matsu class, but the design was simplified to facilitate production and the ship was one of those built to the modified design. She was laid down on 21 October 1944 by Yokosuka Naval Arsenal, launched on 27 December and completed on 26 March 1945. Sumire was assigned that day to Destroyer Squadron 11 under the Combined Fleet for working up, and was briefly attached to the Second Fleet on 1–20 April. She was training in the Seto Inland Sea from 1 June to 23 July and was transferred to the Maizuru Naval District on the 15th. The ship was turned over to Allied forces at Maizuru at the time of the surrender of Japan on 2 September and was stricken from the navy list on 5 October. The destroyer was disarmed and used to repatriate Japanese personnel in 1945–1947. Sumire was turned over to Great Britain on 20 August of the latter year and subsequently sunk as a target ship.
