Pentagon pulls the plug on one of the military's most troubled space programs

Key Points:

• The Pentagon has officially canceled the Global Positioning System Next-Generation Operational Control System (OCX) program after 16 years and nearly $6.3 billion spent, citing insurmountable system issues discovered during testing that risked current GPS capabilities.
• OCX was intended to manage new signals from the latest GPS III satellites and included new control stations, but despite delivery in 2025, it failed to meet operational readiness, leading the Space Force to continue upgrading the legacy GPS control system instead.
• The decision follows a history of cost overruns and delays, with the program initially budgeted at $3.7 billion and scheduled for completion in 2016, but costs nearly doubling and the schedule extending by a decade.
• The Space Force plans to enhance the existing control system to support new GPS satellite capabilities, such as the military-grade M-code signals, while awarding contracts to companies like Lockheed Martin for ground system upgrades related to next-generation GPS IIIF satellites.
• The OCX cancellation highlights challenges in large defense software acquisitions, prompting calls for faster, incremental delivery approaches rather than complex, all-or-nothing projects, reflecting lessons learned from OCX’s troubled development.
