Master Chief Petty Officer of the Navy

The master chief petty officer of the Navy (MCPON /ˈmɪkpɒn/) is a unique non-commissioned rank and position of office of the United States Navy, which is designated as a special paygrade above E-9. The holder of this position is the most senior enlisted member of the U.S. Navy, equivalent to the sergeant major of the Army, chief master sergeant of the Air Force, sergeant major of the Marine Corps, master chief petty officer of the Coast Guard, and chief master sergeant of the Space Force. The holder of this rank and position is typically the most senior enlisted sailor in the Navy, unless an enlisted sailor is serving as the senior enlisted advisor to the chairman. The current MCPON is John Perryman.

The master chief petty officer of the Navy is appointed by the chief of naval operations to serve as a spokesperson to address the issues of enlisted personnel to the highest positions in the Navy.

Their personnel code is N00D as the senior enlisted advisor to Chief of Naval Operations and PERS-00D in their special advisory capacity to Chief of Naval Personnel/Deputy Chief of Naval Operations (Manpower, Personnel, and Training). In 1988, the MCPON's spouse was made the Ombudsman-at-Large, authorizing them to travel around the fleet with their spouse, representing the interests of the spouses of enlisted members. The MCPON serves an appointed two-year term of office but can be reappointed by the CNO for an additional two-year term. Typically; the MCPON serves two terms. While the MCPON is a non-commissioned officer, this rank is protocoled higher than all rear admirals and equivalent to a vice admiral in billet, seating, transportation, and parking.
