Saltzman Puts a Number on the Space Force's Future: 30,000 Satellites by 2040

The U.S. Space Force on April 15 released unclassified versions of two foundational planning documents, the 68-page Future Operating Environment 2040 and the 104-page Objective Force 2040, during Chief of Space Operations Gen. Chance Saltzman's keynote at the 41st Space Symposium in Colorado Springs. Together they project a U.S. government on-orbit fleet of 30,246 satellites by 2040, up from 7,291 in 2025, and commit the service to an operational on-orbit refueling and space-tug architecture phased across the next 15 years.

According to Breaking Defense's Theresa Hitchens, the plan calls for demonstrating on-orbit refueling and fielding "Augmented Maneuver" space tugs between 2025 and 2030, making refueling operational and demonstrating high-thrust reusable orbital transfer vehicles between 2030 and 2035, and standing up an "initial on-orbit logistics architecture" between 2035 and 2040. The fiscal 2027 budget already funds refueling demonstrations, and the Space Force's Andromeda (RG-XX) GEO constellation solicitation issued January 17 included refueling capacity as a requirement for the first time. Saltzman also told reporters the service will pursue new kit for orbital warfare, though specifics remain classified.

The doctrinal shift is the story. The Space Force spent years publicly skeptical of U.S. Space Command's push for on-orbit mobility. Objective Force 2040 now writes proliferation, maneuverability, and refueling into official service doctrine. The plan also projects China operating 20,913 satellites by 2040, up from 1,871, and frames commercial integration as structural rather than supplementary. Saltzman declined to name a specific Guardian end-strength target but said the service should roughly double its current ~8,600 personnel over the next decade.

Saltzman avoided one number throughout: the dollar figure. The plan covers acquisition, infrastructure, training, and workforce across 15 years without a top-line cost.

On-orbit logistics, proliferation, and maneuver are no longer demonstration programs. They are the official force design for 2040, and FY27 is the first legible budget marker.
