World War II

Tenth Fleet's mission included the destruction of enemy submarines, the protection of coastal merchant shipping, the centralization of control and routing of convoys, and the coordination and supervision of all USN anti-submarine warfare (ASW) training, anti-submarine intelligence, and coordination with the Allied nations. The fleet was active from May 1943 to June 1945.[3] Tenth Fleet used Commander-in-Chief Atlantic's ships operationally; CinCLANT issued operational orders to escort groups originating in the United States. The Fleet was also responsible for the organization and operational control of hunter-killer groups. Chief of Naval Operations Admiral Ernest King was the fleet's commander, with Rear Admiral (RADM) F.S. Low, King's assistant chief of staff for ASW, as fleet chief of staff, Admiral Low was later relieved by RADM Allan Rockwell McCann, who remained in command of 10th Fleet until it was deactivated. Tenth Fleet never put to sea, had no ships, and never had more than about 50 people in its organization. The fleet was disbanded after the surrender of Germany.
