WASHINGTON — The Defense Advanced Research Projects Agency is soliciting input from the space industry on how the United States could rapidly restore critical space capabilities if satellites were disabled or destroyed during a conflict.
DARPA on June 12 released a request for information titled “Rapid Reconstitution of Space Capabilities,” seeking responses by July 8.
In the notice, DARPA’s Strategic Technology Office asks for technical concepts and operational strategies that could quickly restore satellites and other space-based capabilities degraded by anti-satellite weapons, cyberattacks, orbital debris or other disruptions. The agency said its objective is to reestablish critical services on timelines measured in hours to weeks.
The effort reflects Pentagon concerns that space is becoming an increasingly contested domain. U.S. military operations rely heavily on satellites for communications, intelligence collection, missile warning, and positioning, navigation and timing services. Defense officials have repeatedly warned that China and Russia are developing counterspace capabilities ranging from direct-ascent anti-satellite weapons to electronic warfare and cyber systems designed to disrupt space infrastructure.
The military has already launched several initiatives aimed at improving its ability to recover from losses in orbit. The U.S. Space Force’s Tactically Responsive Space, or TacRS, program focuses on rapidly deploying replacement satellites when urgent needs arise. In 2023, the Victus Nox mission demonstrated the concept by launching a spacecraft 27 hours after receiving launch orders, setting a new benchmark for responsive launch operations.
The Space Force also established the Commercial Augmentation Space Reserve, or CASR, which uses pre-arranged agreements with commercial satellite operators to provide additional capacity during crises or conflicts. Modeled in part on the Civil Reserve Air Fleet, which gives the military access to commercial aircraft during emergencies, CASR is intended to expand the pool of space services available to the government when needed. DARPA cited the program as one example of ongoing efforts to improve resilience in space.
DARPA’s request points to a broader vision of reconstitution than simply launching replacement satellites or drawing on commercial capacity.
The agency is seeking ideas spanning the entire space architecture, including satellite buses, payloads, launch vehicles, integration processes and operational concepts. Areas of interest include modular spacecraft, plug-and-play components, rapid manufacturing and assembly, software-defined satellites, multifunction spacecraft, alternative positioning and navigation technologies, distributed sensor networks and systems designed to operate in very low Earth orbit. DARPA is also interested in concepts for on-orbit assembly and deployment, supply-chain improvements and methods to reduce production bottlenecks across the space industry.
The notice highlights concerns that limited launch capacity and launch frequency could constrain the military’s ability to replace lost assets quickly. As a result, DARPA appears interested in architectures built around reconfigurable, software-defined and multi-mission systems that can be adapted to changing requirements rather than replacing satellites with identical copies.
