The naval forces involved can be summarized as follows:

Command structure

Theater and operational commanders
Vice Adm. Raymond A. Spruance
Rear Adm. Richmond Kelly Turner
Maj. Gen. Holland M. Smith
Divisional commanders
Maj. Gen. Thomas E. Watson, USMC

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.
