Final answer:
The Chief of Naval Operations is responsible for ensuring that U.S. Navy regulations meet current needs of the Navy. This role includes updating and implementing regulations to guide the function of the Navy in accordance with the latest requirements and strategic considerations.
Step-by-step explanation:
The responsibility for ensuring that U.S. Navy regulations meet current Navy needs primarily falls upon the Chief of Naval Operations (CNO). The CNO is a four-star admiral and the senior military officer of the Department of the Navy. The role includes being a member of the Joint Chiefs of Staff and being responsible for the command, utilization of resources, and operating efficiency of the operating forces of the Navy and the Navy shore activities assigned by the Secretary of the Navy.
According to U.S. law and military tradition, one of Congress's powers is 'To make Rules for the Government and Regulation of the land and naval Forces;'. However, the day-to-day responsibility for ensuring that regulations are kept up-to-date with the Navy's current needs falls under the purview of the Chief of Naval Operations, who would implement and adjust regulations as necessary to guide the function of the U.S. Navy according to prevailing requirements and strategic considerations.
