Akashi was a Japanese repair ship, serving during World War II. She was the only specifically designed repair ship operated by the Imperial Japanese Navy. The navy based her design on the US Navy's USS Medusa.

Construction

Line drawing of Akashi as she appeared in 1940

In 1937 the Imperial Japanese Navy had converted the old battleship Asahi to serve as a repair ship. After the conversion of Asahi, a decision was made to build a dedicated repair ship with better capabilities for that task. The Imperial Japanese Navy planned for her to carry out 40% of the repairs needed by the Combined Fleet (needing approximately 140,000-man-hours). Therefore, she was equipped with the latest machine tools imported from Germany.

War service

Akashi in February 1943 at Truk

During the war Akashi operated out of the Japanese base in the Truk atoll where she repaired various types of battle-damaged Japanese warships, including Shōkaku in October 1942 and Yamato in December 1943. In February 1944 the Americans made a raid on Truk (Operation Hailstone), sinking and damaging many ships. Akashi was damaged in these attacks and escaped to the Japanese atoll of Palau.

Fate

Akashi under attack on 30 March 1944 at Palau

On 30 March 1944, while anchored off Urukthapel in the Palau Islands, Akashi was hit numerous times by bombs and rockets from American aircraft from Task Group 58, during Operation Desecrate One. She was sunk in shallow water with her bridge still remaining above the water.
