Appointment and responsibilities

The chief of space operations appoints the chief master sergeant of the Space Force. To be appointed, the appointee must have at least 22 years of service and must have been a chief master sergeant for at least three years.[4]

The chief master sergeant of the Space Force is the highest noncommissioned officer in the Space Force. The chief serves as the senior enlisted advisor to both the chief of space operations and the secretary of the Air Force on all matters regarding the welfare, readiness, morale, proper utilization, and progress of Space Force enlisted members and their families.[3]


The inaugural chief master sergeant of the Space Force, Chief Master Sergeant Roger A. Towberman, was sworn in on 3 April 2020, having previously served as the command chief master sergeant of the Air Force Space Command, and co-currently serving as the senior enlisted leader of the United States Space Command. In addition to being the first chief master sergeant of the Space Force, he is also the second member of the Space Force and its first enlisted member.[3]

The position was originally known as the senior enlisted advisor of the Space Force (SEASF) from 3 April 2020 until it was renamed on 1 February 2021 to chief master sergeant of the Space Force (CMSSF).[5]

In 2023, five chief master sergeants were considered to replace Towberman who is slated to retire. They went through a series of tests, which included an interview by an occupational psychologist, a mock U.S. Congress testimony, a mock town hall with airmen, and an interview with senior Space Force officials, that would guide General B. Chance Saltzman's selection.[4] On May 5, 2023, Saltzman selected John F. Bentivegna to replace Towberman and serve as the second chief master sergeant of the Space Force. His assignment was announced on May 8, 2023.[6]


The first rank insignia worn by the chief master sergeant of the Space Force, was based upon the rank insignia of the Air Force's chief master sergeant rank insignia, with other components, such as the two stars, designed to be consistent with the senior enlisted advisor rank of the other services. The delta, orbit, and globe elements at the center of the rank were taken from the seal of the United States Space Force. However, unlike the insignia of the Chief Master Sergeant of the Air Force which has a Laurel wreath around the central star within the rockers, the CMSSF insignia does not.[3] On 20 September 2021, new insignia for all enlisted in the Space Force was introduced, including the CMSSF.[7][8][9]
