RFI: GEO Refueling Vehicles for Sustained Space Maneuver RFI-SML-GEO-Feb2026

The United States Space Force (USSF), Space Systems Command, Servicing, Mobility, and Logistics (SSC/SYD80) Program Office, is seeking information on technical concepts and approaches to Refueling Services for prepared clients in orbit. Background and Need As an enabling technology for the Sustained Space Maneuver need of U.S. Space Command, on-orbit servicing, including refueling, is a vital capability to support warfighter needs. Space System Command s System Engineering Review Board (SERB) has already approved two standard interfaces for satellite refueling Northrop Grumman s Passive Refueling Module (PRM) and Orbit Fab s Rapidly Attachable Fluid Transfer Interface (RAFTI). Industry solutions for refueling of National Security Space assets equipped with these SERB-approved interfaces are sought to meet sustained space maneuver (SSM) needs by 2030. SSC/SYD80 requests feedback from industry intending to provide services. Please review the RFI attachment and respond to the questions if interested in this notice.

Amendment 01 to the RFI The notice has been amended to include an updated RFI document, see attachments. This update clarifies the language under Question 1.b.ii and removes the "NSSL PLUG" reference previously included. No other changes were made to this RFI notice.
