United States Tenth Fleet

The U.S. Tenth Fleet is a functional formation and a numbered fleet in the United States Navy. It was first created as a global anti-submarine warfare coordinating organization under the singular authority of the Commander in Chief, U.S. Fleet (COMINCH), Admiral Ernest J. King, during the Second World War. It was focused upon the destruction of enemy submarines and blockade runners globally, although primarily in the Atlantic and Indian Oceans. Tenth Fleet provided the targeting data required for anti-submarine operations in the Pacific and Arctic Seas as well. King specifically dissolved the Tenth Fleet upon the cessation of hostilities in 1945.

Reactivated as a force provider for Fleet Cyber Command on 29 January 2010. U.S. Tenth Fleet serves as the numbered fleet for U.S. Fleet Cyber Command and exercises operational control of assigned naval forces to coordinate with other naval, coalition and Joint Task Forces to execute the full spectrum of cyber, electronic warfare, information operations, and signal intelligence capabilities and missions across the cyber, electromagnetic, and space domains.
