In peacetime, a Senior Master Chief Petty Officer would have served at least 22 years, with 36 months time in grade as a Master Chief Petty Officer. However, since there are a limited number of vacancies, there is a competitive test to determine who can be promoted, and they need to be approved before the Chief Petty Officer Promotion Board. The Grayson Space Navy uniform is blue with gold stripes with crossed swords. The Royal Manticoran Navy is black and the color of the stripes and rockers change depending on the specialty of the spacer.

If the spacer has completed their Senior Master Chief Petty Officer Exam, and served as a Master Chief Petty Officer for 24 months Time in Grade, they are promoted to this rank.
