How many silver stars denote a Master Chief Petty Officer?

The rank of Master Chief Petty Officer (MCPO) is denoted by the use of two silver stars on their insignia. In the U.S. Navy and Coast Guard, the use of stars signifies higher ranks within the Chief Petty Officer (CPO) category. Specifically, the Master Chief Petty Officer rank is distinguished by having two silver stars positioned above the eagle insignia.

This is significant as it distinguishes the Master Chief from both Chief Petty Officers, who have one silver star, and Senior Chief Petty Officers, who have one silver star plus an additional chevron. The two silver stars indicate the highest enlisted ranking within the Navy's chief structure and signify the experience, leadership, and seniority of the individual holding that position.

Other options do not accurately reflect the insignia for the Master Chief Petty Officer rank, as having no stars, one star, or three stars do not pertain to this specific rank designation. This is why two silver stars is the correct representation for a Master Chief Petty Officer.
