Space Force lays out plan to double its ranks in five years

Senior Space Force leaders used the Air and Space Forces Association’s annual conference on Sept. 14 to lay out a five-year plan to expand the service’s ranks, overhaul training pipelines and accelerate construction of critical infrastructure.

The “Growth of the Space Force” panel brought together Lt. Gen. Gregory Gagnon, commander of U.S. Space Force Combat Forces Command; Maj. Gen. James Smith, who leads Space Training and Readiness Command; Kathryn Kolbe, assistant deputy chief of Space Operations for Installations and Logistics; and Chief Master Sgt. of the Space Force John Bentivegna. Retired Air Force Gen. Kevin Chilton, explorer chair at the Mitchell Institute for Aerospace Studies’ Spacepower Advantage Center of Excellence, moderated.

“Over the past seven years, combat operations have proven the value of the new focus on space superiority,” Chilton said. “At the same time, additional missions and operational demands are stretching the personnel and resources of our smallest service. Meeting these demands requires growing the Space Force with people, training equipment, infrastructure, more fighting capacity — all necessary to deter aggression and to operate through attack and deliver spacepower at the speed and scale today’s threat environment demands, but doubling the size of the Space Force is easier said than done.”

Gagnon said operational demand has outpaced available capacity across every theater and argued that growth must match that reality. “The demand signal is growing exponentially,” he explained. “Across every geographic combatant command, requests for spacepower far outpace current availability. Controlling 33% to 50% more satellites today than two years ago is only the baseline; in three years, that workload will expand fivefold. Operating at that scale requires expanding total force capacity from under 11,000 Guardians to roughly 25,000.” Bentivegna added: “Doubling the size just makes sense for the lethality we provide the Joint Force.”

Meeting those targets hinges on a sharp ramp in training throughput. Smith said Space Training and Readiness Command is preparing a fiscal 2027 surge from about 1,000 accessions to roughly 3,000 in a single year, including a fourfold increase in officer production. “The goal is to create a force that can deter and win if necessary,” Smith said. “So, while we must succeed at doubling, ultimately, we must succeed at the greater mission, which is protecting our nation’s interest in, from and to space,” he continued.

Bentivegna stressed that quality standards will hold even as numbers rise. “STARCOM is a filter, not a pump,” he emphasized. To streamline progression from accession to operations, the command has condensed nearly 20 months of intelligence, cyber and operational instruction into a single Officer Training Course and launched a dedicated Guardian Basic Military Training.

Infrastructure loomed as a parallel constraint. Kolbe outlined shortfalls spanning new weapon systems, launch facilities, training spaces and support buildings, and said the service is creating an Infrastructure Delivery Authority to speed projects, draw on private-sector expertise and apply newly available authorities under the Fiscal 2026 National Defense Authorization Act. She also highlighted efforts to harden and disperse ground architecture, pointing to programs such as Satellite Control Augmentation Resiliency and commercial partnerships through the Joint Antenna Marketplace to proliferate global ground nodes.

Leaders repeatedly tied growth to the needs of the force at the tactical edge. Addressing Guardians directly, Bentivegna said: “For the Guardians that are in the audience, all this discussion about growing a service – you know the amazing work you’re doing. You know how hard you are working. You know how you are valued by the joint and coalition force,” Bentivegna said. “We’ve heard you, and we are moving out. From our positions, we are advocating to get you the resources and the time you need so we can do the investments. For those of you who are helping us with the budget, I hope you listen to what we say.”

Kolbe linked those personnel investments to mission assurance. “Installations, infrastructure, sustainment and logistics are a key enabler for warfighting capability for the Space Force,” Kolbe added. “That is our focus, and we will continue to work to improve those resources to provide enhanced warfighting capacity. And we are moving as quickly as we can. We will leverage all the legislative authorities that we can that have been made available to us, and we plan to partner closely with the private sector to leverage their expertise and innovation to get to where we need to go.”

Smith expressed confidence that the service can execute on the mandate. “We will absolutely succeed at meeting and executing the task we’ve been given to grow in size, thanks to the partnerships across the Space Force and the Joint Force in helping us make that happen,” he said.

Gagnon underscored that the end goal is combat credibility, with a near-term focus on training realism. “Space superiority is a joint priority, but they are asking you, all of you to lead it and deliver it,” Gagnon said. “Space superiority starts with space control. Space control and combat power starts with training and rehearsal. Today, 60% of Combat Forces Command lacks a full simulation trainer. We have worked on a roadmap with our teammates in STARCOM and Space Systems Command to close that gap by over half in the next 36 months. That is critical capability that might not be seen in outer space. It might not be seen on a runway. It’ll be inside those resilient ops centers that Kathryn is going to build, but that is the special sauce that will deliver combat credibility to the Joint Force, and in turn, continue to deliver the high ground for America.”

The panel’s through line: headcount growth alone is insufficient. Leaders said sustained investment must move in lockstep across people, training capacity, equipment, resilient operations centers, ground networks, simulators and sustainment to generate the combat power required for enduring space superiority.
