The US Space Force took delivery of the GPS Next-Generation Operational Control System (OCX) from RTX Corporation—formerly Raytheon—last July, marking a formal handover of a project that was originally meant to be finished in 2016 at a cost of $3.7 billion. Instead, the ground control system for the GPS III satellites now carries a price tag of $7.6 billion, with an additional $400 million in planned costs for supporting the upcoming GPS IIIF satellites, bringing the total to $8 billion. Despite the transfer, the system remains nonoperational. Thomas Ainsworth, assistant secretary of the Air Force for space acquisition and integration, told Congress that extensive testing with live GPS infrastructure revealed unresolved technical issues across all subsystems. The problems have persisted for over 15 years, marked by repeated delays and ballooning costs. In the meantime, the military has patched together upgrades to the legacy control system, enabling limited use of advanced M-code signals since 2020. These encrypted, jam-resistant signals are critical for military operations, especially in conflict zones like Ukraine and the Middle East, where GPS spoofing is common. Originally, full M-code functionality required OCX, which was supposed to command the newer GPS III satellites launched starting in 2018. The ground segment includes two master control stations and upgraded monitoring stations worldwide, but its failure to become operational threatens future satellite capabilities.
When Thomas Ainsworth says testing uncovered "extensive system issues across all subsystems," that means the $8 billion OCX system isn't just late—it may be fundamentally unfit for purpose. The fact that the military still relies on decades-old infrastructure to run cutting-edge satellites exposes a dangerous gap between technological ambition and execution. For global defense tech projects, this isn't just a budgetary failure; it's a signal that complexity without deliverability can compromise national security.
