AKASHI is anchored in Truk's Repair Anchorage located W of Dublon and N of Fefan Islands. At the time of Task Force 58's raids, the destroyer FUMIZUKI and KIYOSUMI, YAMAGIRI, HOYO and KENSHO MARUs and TONAN MARU NO. 3 are in this anchorage waiting or undergoing repairs. Prior to the raids, AKASHI probably performed repairs on most, or all, of these ships.

During the two days of the raid, TF 58 sinks 31 transports and 10 naval vessels (two cruisers, four destroyers and four auxiliary vessels), destroys nearly 200 aircraft and damages severely about 100 more. Truk is eliminated as a major fleet anchorage for the IJN.

28 March 1944:

30-31 March 1944: American Operation “Desecrate One”:
Palau. The anchorage is attacked by F6F "Hellcats", SBD "Dauntless", TBF "Avenger" and SB2C "Helldiver" carrier aircraft of Task Group 58. 1's USS ENTERPRISE (CV-6), BELLEAU WOOD (CVL-24) and COWPENS (CVL-25), TG 58. 2's BUNKER HILL (CV-17), HORNET (CV-12), MONTEREY (CV-26) and CABOT (CVL-28) and TG 58. 3's YORKTOWN (CV-10), LEXINGTON (CV-16), PRINCETON (CVL-23) and LANGLEY (CVL-27).
Palau Harbor. TF 58's planes find AKASHI anchored in shallow water in a cove off the northern part of Urukthapel Island. She sustains numerous direct hits and near misses by bombs and rockets. AKASHI suffers at least seven hits on her stern, two on her port bow, one on her superstructure forward of the well deck, two amidships and another aft of her stack that causes a fierce fire.
AKASHI sinks by the bow in the shallow water. Her bridge, crane tops and masts remain above water. Captain Kameyama and an unknown number of crewmen survive. Thirty-five other ships are sunk in the raid.
The Fujita Salvage Company, under the authority of the Palau Government, salvages numerous wrecks for scrap including the hulk of AKASHI.
10 May 1944:
Removed from the Navy List.
General Note. The TROM lists numerous ships for which AKASHI provided various degrees of repair. She was the most fully equipped repair ship in the IJN. While many ships that underwent repairs are listed by name in source documents, others are not, but their repairs most probably were carried out in whole or part by AKASHI. The Japanese estimated that she alone could carry out 40 percent of the repairs needed by the Combined Fleet. Other, smaller, repair ships also carried out repairs at Truk, but AKASHI probably participated to some degree in most of those efforts as well.
 Some sources erroneously credit USS SCORPION (SS-278) with torpedoing of HOYO MARU.
