The Space Force is promoting new noncommissioned officers at a breakneck pace, as the service announced another year of sky-high rates for junior NCOs.
More than four out of every five eligible Guardians were selected for promotion to either sergeant or technical sergeant in 2025, according to statistics from the Air Force Personnel Center. The full list of selectees was released July 17.
Nearly every specialist 4 looking to become a sergeant got the nod, with a 96.03 percent rate. That’s even higher than last year’s 95.66 percent. Of those selected, the average time in grade was 0.95 years and time in service was 3.38 years.
Those times in grade and service are the lowest in the Space Force’s brief history and stand in contrast to the Air Force—the average time in grade for Senior Airmen selected for staff sergeant hasn’t dipped below 1.6 years for at least nine cycles, and the time in service has stayed above four years.
Space Force leaders have said they want to revamp how they do promotions for sergeants, moving to what they call a “fully qualified” system where every E-4 who meets the qualifications will be promoted, removing any limits on the number of eligible candidates. For this cycle, however, Guardians went through the existing process in which candidates are scored and ranked based on their performance and training records, then picked by a selection board.
The selection rate for sergeants looking to move up to technical sergeant was well below the E-5 rate, but still up slightly over last year at 68.16 percent. The average time in grade was 3.39 years and time in service was eight years. Like the sergeant selectees, the time in grade and time in service are less than what the Air Force typically sees for its equivalent rank. The last nine USAF E-6 promotion cycles have featured time in grade averages above 4 years and time in service averages above 9 years.
All told, the 2025 Space Force cycle saw 733 promotions for sergeant and technical sergeant out of 896 eligible Guardians: 81.8 percent.
| YEAR | Sergeant | Technical Sergeant | Master Sergeant |
|---|---|---|---|
| 2025 | 96.03 percent | 68.16 percent | 18.22 percent |
| 2024 | 95.66 percent | 63.87 percent | 21.34 percent |
| 2023 | 72.08 percent | 34.97 percent | 30.18 percent |
| 2022 | 66.91 percent | 33.23 percent | 29.89 percent |
Unsurprisingly, the Space Force’s end strength in those grades has swelled in recent years. In 2023, when promotion rates were 20 percentage points lower for both grades than they are now, the service had 1,058 sergeants and 826 technical sergeants. Looking ahead to 2026, when the most recent promotions will come into full effect, USSF is expecting to have 1,274 sergeants and 1,081 technical sergeants—a 25 percent increase compared to a 17 percent increase in total force end strength.
While the junior NCO promotion rates have surged, the Space Force also announced a slightly lower rate for its E-7 master sergeant rank: 18.22 percent, the lowest in the service’s brief history.
