Space Force Explores In-Orbit Satellite Refueling, Allocates $20 Million for Feasibility Study

The U.S. Space Force is seeking industry input on the military utility and business case for in-orbit satellite refueling. The service has allocated $20 million over the next five years to study the concept before making larger investments in the technology.

Lt. Gen. Chance Saltzman, deputy chief of space operations for nuclear and counter-space, stated that the Space Force wants to understand the "military utility" and "business case" for in-orbit refueling before committing to major investments. The goal is to determine if refueling satellites in space can enhance their capabilities and longevity, and whether it makes financial sense for the government to pursue this technology.

While the military sees potential benefits in extending satellite lifetimes and reducing space debris, it is still unclear on the industry's business model and whether the benefits of refueling would justify a larger financial commitment. The Space Force is taking a cautious approach, wanting to be a buyer of the capability rather than the prime driver in developing it.

Why this matters: In-orbit satellite refueling could change the way satellites are operated and maintained, potentially extending their lifespans and reducing the need for costly replacements. The Space Force's study will provide valuable insights into the feasibility and benefits of this technology for military applications.

The Space Force is unsure about the military benefits of refueling and wants the commercial sector to help provide clarity on the technology and its potential uses. They want to understand if refueling would give them a competitive advantage in peacetime and wartime, and are looking for evidence to justify the investment.

"The refueling business model is still not widely proven, and the Space Force is willing to fund research but is reluctant to make major commitments until a viable model emerges," Lt. Gen. Saltzman said. The Space Force sees refueling as a way to extend satellite life cycles and reduce space debris, but needs to evaluate the military utility before deciding on further funding.
