APRIL 21, 2026 – The Global Positioning System Next Generation Operational Control System program was cancelled by the Defense Acquisition Executive on April 17, based upon the recommendation of the acting service acquisition executive.
OCX was intended to update command and control of the GPS satellite constellation, replacing the current system, known as the Architecture Evolution Plan, as well as replacing the Launch, Anomaly and Disposal Operations system. However, the program was unable to deliver needed capabilities on an operationally relevant timeline at an acceptable level of risk to meet the GPS constellation modernization needs.
“It’s important we refine and update acquisition processes to prioritize rapid, incremental capability delivery versus complex ‘all or nothing’ system deliveries,” said Acting Service Acquisition Executive Tom Ainsworth. “The Department of War has made clear that we need to deliver warfighting capability at a faster rate. We must continue to work with industry to meet the needs of our warfighters as we focus on delivering the right technology on the right timeline to enhance our capabilities and maintain space superiority.”
In July 2025, following a multi-year regimen of factory testing, the Space Force contractually accepted OCX from Raytheon and began extensive integrated systems testing to resolve liens carried over from factory testing, as well as to ensure the system could operate within the broader GPS enterprise of ground systems, satellites, and user equipment.
As of January 2026, the program cost was approximately $6.27 billion which included complete Raytheon funding to date and other government costs, such as the cost of government testing and support costs to the OCX acquisition program office.
“Regrettably, extensive system issues arose during the integrated testing of OCX with the broader GPS enterprise,” said Mission Delta 31 Commander Col. Stephen Hobbs. “Despite repeated collaborative approaches by the entire government and contractor team, the challenges of onboarding the system in an operationally relevant timeline proved insurmountable. We discovered problems across a broad range of capability areas that would put current GPS military and civilian capabilities at risk.”
Due to past delays on the OCX program, the Space Force has made incremental improvements over the last 10 years to AEP. These successful upgrades provide confidence that further upgrades to GPS ground systems will continue to support the enterprise and deliver new capabilities.
“Ultimately, we analyzed the work remaining on OCX and compared this with the current GPS control system capability,” Hobbs said. “The analysis revealed additional investment in OCX was no longer the best solution for protecting and advancing GPS capabilities. Instead, we will continue enhancing the current control system to operate the GPS satellite constellation.”
