Okinawa naval order of battle

For the April 1945 invasion of Okinawa, the Allies assembled the most powerful naval force in history. Since the few remaining capital ships of the Imperial Japanese Combined Fleet had been sunk or otherwise put out of action at the Battle of Leyte Gulf, the Allies were effectively unopposed in terms of surface vessels; a single mission consisting of the superbattleship JAPANESE BATTLESHIP Yamato and a few escorts was undertaken, but the task force did not get within 200 nmi of the invasion area.

Since the Japanese air arm had been equally decimated by this point in the war, the lack of trained and experienced pilots led them to deploy the kamikaze extensively in the waters off Okinawa.

The roles of Commander in Chief, Pacific Ocean Areas (CINCPOA) and Commander in Chief, U.S. Pacific Fleet (CINCPAC), were both exercised by Admiral Chester W. Nimitz from his headquarters at Pearl Harbor, Hawaii.

Since the "Big Blue Fleet" was at this time under the command of Admiral Raymond Spruance aboard his flagship USS Indianapolis (CA-35), the force was designated Fifth Fleet. (It had been Third Fleet until Spruance relieved Admiral William Halsey in January, as part of the "alternating command" system).

The ships and troops of Operation Iceberg were under direct operational command of Rear Admiral Richmond Kelly Turner aboard amphibious command ship USS Eldorado (AGC-11).
