The structure of the organization to accomplish this purpose shall be such as the Secretary of the Navy may deem appropriate and necessary, with due regard for the necessity for delegation and decentralization.

The Marine Corps is an integral part of the naval establishment. In time of war or when the President shall so direct, the Coast Guard is a part of the naval establishment.
