The Mutsuki class was an improved version of the Kamikaze-classdestroyers and was the first with triple 61-centimeter (24 in) torpedo tubes. The ships had an overall length of 102.4 meters (335 ft 11 in)[1] and were 94.54 meters (310 ft 2 in) between perpendiculars. They had a beam of 9.16 meters (30 ft 1 in), and a mean draft of 2.96 meters (9 ft 9 in). The Mutsuki-class ships displaced 1,336 metric tons (1,315 long tons) at standard load and 1,800 metric tons (1,772 long tons) at deep load.[2] They were powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by four Kamponwater-tube boilers. The turbines were designed to produce 38,500 shaft horsepower (28,700 kW), which would propel the ships at 37.25 knots (68.99 km/h; 42.87 mph). The ships carried 420 metric tons (413 long tons) of fuel oil which gave them a range of 4,000 nautical miles (7,400 km; 4,600 mi) at 15 knots (28 km/h; 17 mph). Their crew consisted of 150 officers and crewmen.[3]
The main armament of the Mutsuki-class ships consisted of four 12-centimeter (4.7 in) Type 3 guns in single mounts; one gun forward of the superstructure, one between the two funnels and the last pair back to back atop the aft superstructure. The guns were numbered '1' to '4' from front to rear. The ships carried two above-water triple sets of 61-centimeter torpedo tubes; one mount was between the forward superstructure and the forward gun and the other was between the aft funnel and aft superstructure. Four reload torpedoes were provided for the tubes.[3] They carried 18 depth charges and could also carry 16 mines. They could also fitted with minesweeping gear.[4]
Kikuzuki was one of six Mutsuki-class ships reconstructed in 1935–36, with their hulls strengthened, raked caps fitted to the funnels and shields to the torpedo mounts. In 1941–42, most of those ships were converted into fast transports with No. 2 and No. 3 guns removed. In addition, ten license-built 25 mm (1.0 in) Type 96 light AA guns[2] and at least two 13.2 mm (0.5 in) Type 93anti-aircraft machineguns were installed.[5] The minesweeping gear was replaced by four depth charge throwers and the ships now carried a total of 36 depth charges. These changes reduced their speed to 34 knots (63 km/h; 39 mph)[6] and increased their displacement to 1,944 metric tons (1,913 long tons) at normal load.[3] Three more 25 mm guns may have been added in 1942.[6]
Construction and career
Kikuzuki, built at the Maizuru Naval Arsenal, was laid down on 15 June 1925,[2]launched on 15 May 1926[4] and completed on 20 November 1926. Originally commissioned simply as Destroyer No. 31, the ship was assigned the name Kikuzuki on 1 August 1928.[3] In the late 1930s, she participated in combat during the Second Sino-Japanese War, covering the landings of Japanese troops in central and southern China, and the invasion of French Indochina.
