title: Master chief petty officer text: Master chief petty officer Master chief petty officer (MCPO) is the ninth, and highest, enlisted rate (pay grade E-9) in the United States Navy and United States Coast Guard, just above senior chief petty officer (SCPO). Master chief petty officers are addressed as "Master Chief (last name)" in the colloquial 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 title: Master chief petty officer text: petty officer (FLTCM) 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 (MCPON, pronounced "mick-ponn"). The holder of this post is 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 (silver on the gold foul anchor collar device).

The stars for Command Master Chief are silver, while stars for Fleet or Force Master Chief are gold.

By reporting directly to their commanding officer, the CMDCMs keep their chain of command aware and informed of sensitive and current issues. The Bureau of Personnel assigns a CMDCM to commands with 250 or more enlisted manpower. All carrier-based air wing squadrons, deployable helicopter anti-submarine warfare light, helicopter combat support, and maritime patrol squadrons will have a CMDCM requirement regardless of size due to the complexity of their operations. Those commands that do not have enlisted manpower of 250 assign a CMDCM from within command resources on a collateral duty basis. In the absence of a master
