Space Force Relaunches SCAR Competition After Terminating $1.7 Billion AeroVironment Contract

Following the cancellation of a major satellite-control antenna deal that ended in pricing disputes and contractor losses, the U.S. Space Force is opening fresh competition to modernize the ground infrastructure that tracks and manages its growing satellite fleet.

Space Force Resets Satellite Control Antenna Program

What Happened

The termination, reported in March 2026, came after the Space Force and AeroVironment failed to reach agreement on a firm-fixed-price contract structured around a commercialized product solution.

The SCAR program was designed to modernize the network of ground-based antennas used to track, communicate with, and manage Pentagon and other U.S. government satellites★.

The Procurement Reset

Rather than abandon the requirement, the Space Force moved quickly to re-engage industry. In April 2026, the service issued a request for information asking companies to describe what existing antenna infrastructure they could bring to bear. That market-sounding phase has now progressed: as of late June 2026, the Space Force is actively seeking fresh bidders for a relaunched SCAR competition.

The shift in approach reflects a broader lesson from the failed award — that locking into a single contractor without a settled commercial product pathway carries real programmatic risk. By re-opening the competition and soliciting information about available commercial infrastructure first, the Space Force is signaling it wants a more market-grounded solution this time around.

Industrial and Operational Implications

For the defense industrial base, the restart creates a new competitive opening. AeroVironment's exit from the program removes the incumbent advantage★, and any company with antenna manufacturing, satellite operations, or ground-system integration capabilities could now enter the race. The prior stop-work order and pricing impasse also serve as a cautionary signal: the Space Force appears unwilling to absorb cost and schedule risk from a program that cannot converge on fixed-price terms★.

Operationally, the delay in modernizing satellite-control antenna infrastructure carries real consequences. Managing an increasingly complex on-orbit architecture with aging or inadequate ground infrastructure creates a growing mismatch that SCAR was meant to close★.

What's Next

The Space Force has not publicly disclosed a timeline for awarding a new SCAR contract, nor has it named potential competitors in the relaunched competition★. The outcome will have lasting consequences for how the military commands and controls its satellite assets — and for which contractors shape the next generation of military space ground systems.
