Harutsuki (春月, "Spring Moon") was an Akizuki-class destroyer of the Imperial Japanese Navy. Her name means "Spring Moon". She was different from her other sisters, as she was built as a flagship for the Escort Fleet.
The Akizuki-class ships were originally designed as anti-aircraft escorts for carrier battle groups, but were modified with torpedo tubes and depth charges to meet the need for more general-purpose destroyers. The ships measured 134.2 meters (440 ft 3 in) overall, with beams of 11.6 meters (38 ft 1 in) and drafts of 4.15 meters (13 ft 7 in). [1] They displaced 2,701 long tons (2,744 t) at standard load [2] and 3,420 long tons (3,470 t) at deep load. [3] Their crews numbered 300 officers and enlisted men. [2]
Each ship had two Kampon geared steam turbines, each driving one propeller shaft using steam provided by three Kampon water-tube boilers. The turbines were rated at a total of 52,000 shaft horsepower (38,776 kW) for a designed speed of 33 knots (61 km/h; 38 mph). The ships carried enough fuel oil to give them ranges of 8,300 nautical miles (15,400 km; 9,600 mi) at speeds of 18 knots (33 km/h; 21 mph). [4]
The main armament of the Akizuki class consisted of eight 100-millimeter (3.9 in) Type 98 dual-purpose guns in four twin- gun turrets, two superfiring pairs fore and aft of the superstructure. They each carried a dozen 25-millimeter (1 in) Type 96 anti-aircraft (AA) guns in four triple-gun mounts. The ships were also each armed with four 610-millimeter (24 in) torpedo tubes in a single quadruple rotating mount amidships; one reload was carried for each tube. [5] The later batches of ships were each equipped with six depth charge throwers for which 72 depth charges were carried. Harutsuki was equipped with a Type 21 early-warning radar on her foremast. [6]
On 5 October 1945, Harutsuki was removed from Navy List. On 28 August 1947, she was turned over to the Soviet Union, renamed Vnezapny (Внезапный) and rearmed with eight 102-millimeter (4 in) guns, fifteen 25 mm guns and four 533-millimeter (21 in) torpedo tubes. She became the training ship Oskol in 1949, target ship TsL-64 in 1955 and finally floating barracks PKZ-37, scrapped in 1969.
