The Asashio-class destroyers (朝潮型駆逐艦 Asashio-gata kuchikukan) were a class of ten destroyers of the Imperial Japanese Navy in service before and during World War II.[1]
Background
The Imperial Japanese Navy was not entirely satisfied with the performance of the Shiratsuyu-class destroyer, particularly in terms of operational range and speed. However, given the limitations of the 1930 London Naval Treaty, it was considered impossible to modify these vessels any further to improve their specifications. This obstacle was removed after the Japanese government allowed the treaty to expire without renewal. The final four vessels of a projected 14 destroyers in the Shiratsuyu class were cancelled, and the larger new Asashio-class vessels were approved under the Maru-2 Supplementary Naval Expansion budget of 1934, with construction spanning 1935-1936. All ten vessels were lost in the Pacific War.[2]
Design
The Asashio class was the first Japanese destroyer class to exceed 2,000 tons displacement and the first to be equipped with sonar. Early critical issues with the Asashio class included the reliability of their new steam turbines engines, and issues with the design of their rudder, which were addressed by the start of the Pacific War.
In terms of armament, the Asashio class was similar to the previous Fubuki and Akatsuki classes, but with twin mount 5-inch guns instead of a single mounts. The guns were mounted in Type C gun turrets capable of 55-degree elevation. Also, the position of the "X" turret at the shelter deck level forward of the quarterdeck "Y" turret, gave the Asashio class a different silhouette than the Shiratsuyu class, where both turrets were at quarterdeck level. The torpedo armament of eight 24-inch torpedo in two quadruple launchers was retained, with the torpedo reloads stored in a deckhouse on the centerline. This design became the basic plan for all future destroyers in the Japanese navy.
The Asashio-class vessels had three boilers running two geared turbine shafts with an output of 50,000 hp (37,000 kW) at the screws, giving it a top speed of 35 knots (65 km/h) and a range of 5,700 nautical miles (10,600 km) at 15 knots (28 km/h) or 960 nautical miles (1,780 km) at 34 knots (63 km/h).[3]
In the middle of the Pacific War (1943–44), on surviving vessels the "X" turret was removed and replaced by triple Type 96 25 mm anti-aircraft guns, increasing the total number to 15. After June 1944, even more anti-aircraft guns were added, raising the total to between 15 and 28 Type 96 guns and four Type 93 13 mm guns. Four depth charge throwers and 36 depth charges were also fitted at between 1943 and 1944. The last four surviving vessels were also equipped with Type 13 and Type 22 radar.
Operational history
During the war the Asashio class was used extensively in the protection of the Combined Fleet. Arare was attacked and sunk off Kiska Island during the Aleutian Islands Campaign by USS Growler on 5 July 1942. Kasumi was also heavily damaged along with one other destroyer. Asashio and Arashio escorted the 7th Cruiser Division at the Battle of Midway, where both were damaged by air attack. Although repaired and returned to service, both were sunk in 1943 when a large Japanese transport force was destroyed by American planes in the Battle of the Bismarck Sea. Michishio, Asagumo, and Yamagumo were lost in 1944 in the Battle of Leyte Gulf. Kasumi, last of the class to be laid down, served as escort on the attack on Pearl Harbor and joined the battleship Yamato during Operation Ten-Go against the American fleet at Okinawa. None of the Asashio-class ships survived the Pacific War.[4]
