RTX’s next-generation GPS operational control system (OCX) remains non-operational nine months after delivery. The U.S. Space Force program originally launched in 2010. Initial project costs were estimated at $3.7 billion. Total expenditures have now exceeded $8 billion.
The system missed its original 2016 completion deadline. The Pentagon is now considering the cancellation of the OCX program. Government-led testing since July 2025 revealed significant software defects.
These technical issues require substantial time to remediate. The delay prevents the military from accessing advanced anti-jamming and accuracy features on GPS III satellites. Operations remain dependent on the legacy ground system.
