A Naval Review is an event where select vessels and assets of the United States Navy are paraded to be reviewed by the President of the United States or the Secretary of the Navy. Due to the geographic distance separating the modern U.S. Navy and the deployment rotations of a various ships within a fleet, it would be exceedingly difficult to imagine a situation where even an entire numbered fleet could be presented at one event, to say nothing of the physical cost and logistical requirements to support over 460 ships exceeding 3.4 million tons displacement.
