# Japanese destroyer Shii

Shii (椎, "Castanopsis") was one of 23 escort destroyers of the Tachibana sub-class of the Matsu class built for the Imperial Japanese Navy during the final stages of World War II. Completed in March 1945, she struck a mine in June, but was only lightly damaged. The ship was used to repatriate Japanese personnel after the war until 1947. Mid-year the destroyer was turned over to the Soviet Union, renamed Volny and was commissioned that same year. She was renamed TsL-24 and converted into a target ship two years later; the ship was ordered to be scrapped in 1960.

## Design and description

The Tachibana sub-class was a simplified version of the preceding Matsu class to make them even more suited for mass production. The ships measured 100 meters (328 ft 1 in) long overall, with a beam of 9.35 meters (30 ft 8 in) and a draft of 3.37 meters (11 ft 1 in). They displaced 1,309 metric tons (1,288 long tons) at standard load and 1,554 metric tons (1,529 long tons) 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 19,000 shaft horsepower (14,000 kW) for a speed of 27.8 knots (51.5 km/h; 32.0 mph). The Tachibanas had a range of 4,680 nautical miles (8,670 km; 5,390 mi) at 16 knots (30 km/h; 18 mph).
The main armament of the Tachibana sub-class consisted of three 127-millimeter (5 in) Type 89 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. The ships carried a total of 25 Type 96 25-millimeter (1 in) 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-millimeter (24 in) torpedoes. They could deliver their 60 depth charges via two stern rails and two throwers.

## Construction and service

Shii was ordered in Fiscal Year 1944 under the Wartime Naval Armaments Supplement Program and she was laid down at Maizuru Naval Arsenal on 18 September 1944. The ship was launched on 13 January 1945 and completed on 13 March. Shii 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. On 20 May, she became part of Destroyer Division 43 together with Take, Maki, Tsuta and Kiri which was assigned to Escort Squadron 31 of the Combined Fleet. On 5 June Shii struck a mine in the Bungo Strait and was lightly damaged, although two men were killed and eleven wounded. The ship was turned over to Allied forces at Kure 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. Shii was turned over to the Soviet Union on 5 July of the latter year.
She was commissioned two days later and assigned to the 5th Fleet. The ship was renamed Volny (Вольный (Free)) on 22 July. The destroyer was placed in reserve on 14 February 1949 and was converted into a target ship on 17 June with the name of TsL-24. She was renamed as OT-4 on 18 November 1959 and was ordered to be scrapped on 8 August 1960.
