This is a complete list of four-star generals in the United States Space Force. The rank of general (or full general, or four-star general), ranks above lieutenant general (three-star general) and is the highest rank achievable in the U.S. Space Force. There have currently been only three four-star generals in the history of the U.S. Space Force. All achieved that rank while on active duty. Generals entered the Space Force via several paths: Two were commissioned via the Air Force Reserve Officer Training Corps (AFROTC), and one was commissioned via the U.S. Air Force Academy (USAFA).
