The Pentagon canceled the Global Positioning System Next-Generation Operational Control System (OCX) on April 17 after 16 years of delays and cost overruns that left the system unfit for operational use.
The program’s final delivery failed to meet basic readiness standards
Raytheon, now RTX Corporation, delivered the OCX system to the U.S. Space Force in 2025, but integrated testing revealed persistent flaws across multiple capability areas that could endanger both military and civilian GPS functions.
Colonel Stephen Hobbs cited insurmountable integration challenges
Despite repeated efforts by government and contractor teams, the Space Force’s Mission Delta 31 commander stated that onboarding OCX within an operationally relevant timeline proved impossible due to systemic issues discovered during testing.
The cancellation ends a program that exceeded its original budget by over 100%
Initially awarded in 2010 with a $3.7 billion target and a 2016 deadline, OCX’s final cost approached nearly $8 billion — almost matching the expense of deploying 30 new GPS III satellites — while its timeline slipped by a full decade.
The decision leaves the military relying on legacy systems for GPS control
With OCX terminated, the U.S. Military must continue using older ground control infrastructure to manage GPS III satellites, which began launching in 2018 and transmit enhanced signals the legacy system was not designed to fully process.
RTX acknowledged the cancellation and pledged continued cooperation
An RTX spokesperson confirmed the company received the government’s decision, noted its delivery of the system in 2025, and affirmed its willingness to support the Space Force on next steps for GPS enterprise modernization.

Why was the OCX program canceled after so much investment?
The program was terminated because persistent technical flaws discovered during integrated testing could not be resolved in time to safely support GPS operations, despite years of collaboration between government and contractor teams.
What are the risks of continuing with the legacy GPS control system?
The legacy system may not fully process new signals from GPS III satellites, potentially limiting access to improved accuracy and resilience features for both military and civilian users relying on the global navigation network.
