Towberman, was sworn in on 3 April 2020, having previously served as the command chief master sergeant of the Air Force Space Command, and concurrently 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.<ref name="USSF20200403"/>
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''').<ref>{{Cite web|last=Pawlyk|first=Oriana|date=2021-01-29|title=These Are the Official Space Force Ranks|url=https://www.military.com/daily-news/2021/01/29/these-are-official-space-force-ranks.html|access-date=2021-01-29|website=Military.com|language=en}}</ref>
In 2023, five chief master sergeants were considered to replace Towberman, who was 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.<ref name=vet/> 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.<ref name=next>{{Cite web|url=https://www.spaceforce.mil/News/Article/3388370/chief-master-sgt-john-bentivegna-selected-as-next-chief-master-sergeant-of-the/|title=Chief Master Sgt.

==Insignia==
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.<ref name="USSF20200403"/> On 20 September 2021, new insignia for all enlisted in the Space Force was introduced, including the CMSSF.<ref>[https://twitter.com/SpaceForceDOD/status/1439987571166257159 SpaceForceDOD Twitter, "Chief Master Sergeant of the Space Force Roger A.
