How is the United States Navy structured and operated?

The United States Navy is organized into four main operational bodies: the Office of the Secretary of the Navy, the Office of the Chief of Naval Operations, the operating forces, and the Shore Establishment. It functions within the Department of the Navy alongside the coequal U.S. Marine Corps under the Department of Defense. The fleet maintains a major global presence with extensive air, surface, and submarine capabilities.
