The relationship between the commercial space industry and the Space Force has evolved in recent years. While the Space Force using commercial capabilities is not new, the "buy before build" philosophy has marked a change in acquisition strategy.

Space Systems Command's Commercial Space Office (COMSO) was set up two years ago to better integrate commercial capabilities. This week's On Orbit podcast episode features Lt. Col. Tim Trimailo, director of the Commercial Space Office. Trimailo took the helm of COMSO in April.

Trimailo says that while COMSO has spent time seeding the landscape of commercial capabilities, the focus is shifting to delivering operational capabilities to the warfighter. He also shares the latest on the Commercial Space Augmentation Reserve, the Proliferated Low Earth Orbit, or PLEO IDIQ contract, and takeaways from a recent wargame around space domain awareness.

This interview was part of the GovMilSpace Digital Series, a virtual event that brought together U.S. and allied space, defense, and intelligence leaders to address the evolving threats and priorities shaping tomorrow's missions. The series is available on-demand, with a panel discussion and video interviews featuring the Space Development Agency, UK Ministry of Defense, German BSI, and more. Registration is now open for GovMilSpace 2026, where these critical conversations continue in person during SATELLITE Week.
