Central Marianas naval order of battle

On 15 June 1944, United States Marine and Army forces landed on the southwest coast of the island of Saipan in the central Marianas chain. US forces declared Saipan secure on 9 July. 
Marine Corps forces landed on the nearby island of Tinian on 24 July. Tinian was declared secure 1 August. 
The naval forces involved can be summarized as follows:
Command structure.
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.
Theater and Operational Command.
Since the Marianas lie in the Central Pacific, their capture was the responsibility of the U.S. Fifth Fleet, led by Vice Admiral Raymond A. Spruance from aboard his flagship, heavy cruiser "Indianapolis".
The ships and embarked troops of Operation Forager were under direct operational command of Rear Admiral Richmond Kelly Turner aboard amphibious command ship "Rocky Mount".
The Marine and Army landing forces for Operation Forager were under the command of Maj. Gen. Holland M. "Howlin' Mad" Smith, USMC. Smith directed the ground troops from aboard Vice Adm. Turner's flagship "Rocky Mount" until the afternoon of 17 June when he set up his command post ashore.
