Master chief petty officer is an enlisted rank in some navies. It is the ninth, and highest, enlisted rank in the United States Navy and United States Coast Guard, just above senior chief petty officer. Master chief petty officers are addressed as "Master Chief " in colloquial contexts and they constitute the top 1.25% of the enlisted members of the maritime forces.
Prior to 1958, chief petty officer was the highest enlisted rate in both the U.S. Navy and U.S. Coast Guard. This changed on 20 May 1958 with the passage of Public Law 85-422, the Military Pay Act of 1958, which established two new enlisted pay grades of E-8 and E-9 in all five branches of the U.S. Armed Forces. In the U.S. Navy and U.S. Coast Guard, the new E-8 pay grade was titled Senior Chief Petty Officer and the new E-9 pay grade as master chief petty officer, with the first selectees promoting to their respective grades in 1959 and 1960.

Advancement

In the Navy, advancement to master chief petty officer is similar to that of chief petty officer and senior chief petty officer. It carries requirements of time in service, superior evaluation scores, and selection by a board of master chiefs. Similarly, senior chief petty officers and chief petty officers are chosen by selection boards. In the Coast Guard, advancement to master chief petty officer is similar to other advancements consisting of competition with other advancement-eligible senior chief petty officers. Eligible candidates are prioritized based on written examination scores, evaluations, award points, time in service, and time in grade. Master chief petty officers are then selected monthly from this prioritization list as positions become available.
Petty officers of all grades possess both a rate and rating. The full title is a combination of the two. Thus, a master chief petty officer with the rating of fire controlman would properly be called a master chief fire controlman.
Each rating has an official abbreviation, such as FC for fire controlman, FT for fire control technician, and STS for sonar technician, submarines. When combined with the rate abbreviation, it produces the full rate designation, such as FCCM for master chief fire controlman. It is not uncommon practice to refer to the master chief by this shorthand in all but the most formal correspondence. Mostly, though, they are simply called "Master chief", regardless of rating.
The rate insignia for a master chief is a white eagle with spread wings above three chevrons. The chevrons are topped by a rocker that goes behind the eagle. Two inverted silver stars are placed above the eagle. Between the arc and the top chevron is the specialty mark of the enlisted rating. This is used on the service dress blue, dinner dress blue jacket, and dinner dress white jacket uniforms. On other uniforms, the insignia used for shirt collars and caps is the one that has become universally accepted as the symbol of the chief petty officer. This is a gold foul anchor superimposed with a silver "USN" or a silver shield. As on the rating badge, this is capped by two five-pointed stars, showing one ray down.

Command master chief petty officer

Master chief petty officers are generally considered to be the technical experts in their fields. They serve at sea and ashore in commands of all sizes. Many master chiefs choose to enter the command master chief petty officer program. If selected, a master chief receives additional leadership training and is assigned to a command as the command master chief. The command master chief is the senior enlisted person at a command and as such works as a liaison between the commanding officer and the enlisted ranks, serving as the senior enlisted leader. In this capacity, the CMDCM assists the commanding officer in issues of quality of life, discipline, training, and morale. On submarines, the equivalent of a CMDCM is called the chief of the boat or "COB". The CMDCM insignia has a silver star in lieu of the enlisted rating insignia between the rocker and the top chevron.

Fleet and force master chief petty officer

Fleet and force master chiefs are appointed by the commander of a fleet or a force command, to serve as their senior enlisted adviser. These two ranks are equivalent and their insignia is also the same—a master chief rating badge with two gold stars above the eagle and a gold star for the rating insignia.
A force master chief petty officer is a master chief who has virtually the same responsibility as command master chiefs, but for larger force commands rather than a single unit. There are 15 force master chief positions in the Navy:
A fleet master chief petty officer is a master chief who again has virtually the same responsibility as command master chiefs, but for larger fleet commands. There are four fleet master chief positions in the Navy:
There exists one post that is unique – Master Chief Petty Officer of the Navy. The holder of this post is appointed by the Chief of Naval Operations, to serve as the most senior enlisted member in the U.S. Navy. The MCPON adds a third star above the rating insignia described earlier, and all three stars are gold. Likewise, the rating specialty mark is replaced by a gold star. As of August 2018, Russell L. Smith is the current MCPON.

Master Chief Petty Officer of the Coast Guard

The Master Chief Petty Officer of the Coast Guard is appointed by the Commandant of the Coast Guard to serve as the most senior enlisted member in the U.S. Coast Guard. The MCPOCG adds a third star above the rating insignia described earlier, and all three stars are gold. Likewise, the rating specialty mark is replaced by a gold shield. The current master chief petty officer of the Coast Guard is Jason M. Vanderhaden.
