Japanese destroyer Nagatsuki (1926)
Design and description. The "Mutsuki" class was an improved version of the s and was the first with triple torpedo tubes. The ships had an overall length of and were between perpendiculars. They had a beam of , and a mean draft of . The "Mutsuki"-class ships displaced at standard load and at deep load. They were powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by four Kampon water-tube boilers. The turbines were designed to produce , which would propel the ships at . The ships carried of fuel oil which gave  them a range of at . Their crew consisted of 150 officers and crewmen. The main armament of the "Mutsuki"-class ships consisted of four 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. They carried 18 depth charges and could also carry 16 mines. They could also fitted with minesweeping gear. "Nagatsuki" 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 Type 96 light AA guns and at least two Type 93 anti-aircraft machineguns were installed. 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 and increased their displacement to at normal load. Three more 25 mm guns were added in 1942–43. Construction and career. "Nagatsuki", built at the Ishikawajima Shipyards in Tokyo, was laid down on 16 April 1925, launched on 6 October 1926 and commissioned on 30 April 1927.

She sortied from the Mako Guard District in the Pescadores as part of the Japanese invasion force for Operation M (the invasion of the Philippines), during which time the destroyer helped screen landings of Japanese forces at Lingayen Gulf and at Aparri. While at Lingayen Gulf, "Nagatsuki" suffered light damage due to strafing attacks by USAAF aircraft, which  left one crewman dead and five injured. In early 1942, "Nagatsuki" was assigned to escorting troop convoys from French Indochina for Operation J (the invasion of Java, Netherlands East Indies), From 10 March 1942 "Nagatsuki" and Destroyer Division 5 were reassigned to the Southwest Area Fleet and escorted troop convoy from Singapore to Penang, and Rangoon. The destroyer returned to Sasebo Naval Arsenal for repairs on 19 September, and rejoined the fleet on 9 November, continuing escort patrol duties. At the end of January 1943, "Nagatsuki" escorted the seaplane tender from Sasebo via Truk and Rabaul to Shortlands, and remained  throughout February to cover Operation KE (troop evacuations from Guadalcanal) and to escort convoys to Palau, Wewak and Rabaul. On 25 February, "Nagatsuki" was reassigned to the IJN 8th Fleet. The ship participated in several Tokyo Express troop transport missions throughout the Solomon Islands through the end of June, especially to Kolombangara and Tuluvu. On 4–5 July, while on a run to Kolombangara, "Nagatsuki" engaged the US destroyer , which she helped sink with her torpedoes. However, the following day, during the Battle of Kula Gulf, "Nagatsuki" was holed by a six-inch shot. The ship's captain, Lieutenant Commander Tameo  Furukawa, grounded the vessel near Bambari Harbor on Kolombangara to land his troops; however, later, even with the assistance of sister ship , it proved impossible to refloat the vessel, and she was attacked and destroyed the following day, 6 July, by Allied aircraft. The crew suffered eight dead and thirteen injured, but the survivors later reached the Imperial Japanese Army base at Vila on Kolombangara on foot. "Nagatsuki" was struck from the Navy List on 1 October 1943.
