The Pentagon canceled the Global Positioning System Next-Generation Operational Control System (OCX) on Friday, April 17, 2026, after 16 years of development and nearly $8 billion in spending.
The decision was made by Michael Duffey, the Pentagon’s defense acquisition executive, following persistent technical failures that rendered the system unsuitable for operational use despite delivery to the Space Force in 2025.
OCX was designed to manage signals from the newer GPS III satellites launched since 2018 and to upgrade ground control infrastructure worldwide, but integrated testing revealed widespread capability gaps that risked both military and civilian GPS functions.
Why the OCX program failed after delivery
Col. Stephen Hobbs, commander of Mission Delta 31, stated that extensive system issues emerged during integrated testing with the broader GPS enterprise and repeated efforts by government and contractor teams could not overcome the challenges within an operationally relevant timeline.
RTX Corporation, formerly Raytheon, which received the original $3.7 billion contract in 2010, delivered the system in 2025 and confirmed it would support post-delivery activities while working with the government on next steps.
What this means for the GPS constellation
The cancellation ends a multibillion-dollar effort that had already exceeded the cost of an entire fleet of 30 new GPS satellites, with budget projections swelling from the initial $3.7 billion to nearly $8 billion over a schedule that slipped by a decade.
The Space Force will now demand to rely on legacy control systems while assessing alternatives, though the source does not specify what interim or replacement solutions are under consideration.
What was the original purpose of the OCX program?
OCX was intended to handle new signals from GPS III satellites and modernize the command and control infrastructure for the military’s GPS constellation, including upgrades to master control stations and global ground monitoring sites.
Who made the decision to cancel OCX?
Michael Duffey, the Pentagon’s defense acquisition executive, officially canceled the program on April 17, 2026, as announced by the US Space Force in a press release.
