The Pentagon canceled the Global Positioning System Next-Generation Operational Control System, known as OCX, on Friday, April 17, after 16 years of development and cost overruns that grew from $3.7 billion to nearly $8 billion.
Why the OCX program failed despite delivery of the system
The U.S. Space Force said extensive system issues arose during integrated testing of OCX with the broader GPS enterprise, putting current military and civilian GPS capabilities at risk. Colonel Stephen Hobbs, commander of Mission Delta 31, stated that despite repeated collaborative efforts by government and contractor teams, the challenges of onboarding the system in an operationally relevant timeline proved insurmountable.
What happens next for military GPS operations
The Space Force will continue using the legacy Operational Control System while evaluating next steps for modernizing GPS command and control. RTX Corporation, formerly Raytheon, delivered the OCX system in 2025 and remains committed to supporting the government on future efforts, though no replacement timeline or alternative program was announced in the cancellation notice.
Why was the OCX program canceled after the system was delivered?
Integrated testing revealed unresolved problems across multiple capability areas that would have risked current GPS military and civilian capabilities, making the system unsuitable for operational use despite delivery.
What system is the military using for GPS control now?
The U.S. Space Force continues to rely on the legacy Operational Control System for managing the GPS constellation while assessing future modernization options.
