The Kagerō-class destroyers were outwardly almost identical to the preceding light cruiser-sized Asashio class, with improvements made by Japanese naval architects to improve stability and to take advantage of Japan’s lead in torpedo technology. They were designed to accompany the Japanese main striking force and in both day and night attacks against the United States Navy as it advanced across the Pacific Ocean, according to Japanese naval strategic projections.[2] Despite being one of the most powerful classes of destroyers in the world at the time of their completion, only one survived the Pacific War.[3]
Their crew numbered 240 officers and enlisted men. The ships measured 118.5 meters (388 ft 9 in) overall, with a beam of 10.8 meters (35 ft 5 in) and a draft of 3.76 meters (12 ft 4 in).[4] They displaced 2,065 metric tons (2,032 long tons) at standard load and 2,529 metric tons (2,489 long tons) at deep load.[5] The ships 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 (39,000 kW) for a designed speed of 35 knots (65 km/h; 40 mph). The ships had a range of 5,000 nautical miles (9,300 km; 5,800 mi) at a speed of 18 knots (33 km/h; 21 mph).[6]
Kagerō departed Staring-baai on 27 March to escort the carrier force in the Indian Ocean raid. After the Japanese air strikes on Colombo and Trincomalee in Ceylon, she returned to Kure for repairs on 23 April. She deployed from Saipan on 3 June as part of the escort for the troop convoy in the Battle of Midway. Afterwards, she escorted the cruisers Kumano and Suzuya from Truk back to Kure.
On 5 July, she was assigned to escort the transport Kikukawa Maru to Kiska in the Aleutian Islands on a supply mission, and on 8 August assisted in towing the damaged destroyer Kasumi back to Japan. On 20 July, she was reassigned to Desdiv 15, Desron 2, still within the IJN 2nd Fleet.
In mid-August, Kagerō escorted the cruiser Jintsu to Truk, and continued on from Truk on a high speed transport run to Guadalcanal. For the remainder of 1942 and into February 1943, she was assigned to patrols from Guadalcanal towards Shortland, and to numerous “Tokyo Express" high speed transport operations in the Solomon Islands. During this period, Kagerō escorted aircraft carriers during the battle of the Eastern Solomons on August 24, then escorted carriers at the battle of Santa Cruz on October 26.
In November, Kagerō saw minor roles in two major naval battles. On the 15th, Kagerō was involved in the second naval battle of Guadalcanal, where she took part in a torpedo attack on the battleship USS Washington but failed to damage her as Washington sank the battleship Kirishima and the destroyer Ayanami and sent back the entire force. On the 30th, Kagerō took part on a supply drum transport mission, and in what became the battle of Tassafaronga the convoy was ambushed by a US cruiser force. Near the end of the battle, Kagerō fired her torpedoes at the enemy ships, but failed to make any hits as other destroyers sank one heavy cruiser and crippled three others.[8]
In mid-February 1943, Kagerō returned with the aircraft carrier Junyō via Truk to Kure for repairs. In mid-March Kagerō, Junyō and Hiyō returned to Truk, and Kagerō continued on to Shortlands, arriving on 24 April. After making a troop transport run from Rabaul to Kolombangara on 7 May Kagerō was disabled by a naval mine while leaving Vila port. Barely able to maneuver, she was then attacked by Allied aircraft and sank southwest of Rendova (08°08′S156°55′E / 8.133°S 156.917°E / -8.133; 156.917).[9] On Kagerō , 18 crewmen were killed and 36 were wounded. Kagerō was removed from the navy list on 20 June 1943.
