Space Force Cancels OCX GPS Ground System Following Failed Integrated Testing

The decision signals a pivot to upgrades of the current control system to keep GPS service secure.

Overview

  • The Space Force, which terminated the OCX contract on April 17, said integrated testing with the broader GPS enterprise exposed widespread problems that made timely deployment too risky.
  • Leaders said they will favor rapid, incremental deliveries over large, all-or-nothing programs to cut schedule risk and field usable capability faster.
  • OCX, led by RTX, has cost $6.27 billion through January 2026 after a program that was once slated to be ready in 2016.
  • The service will continue operating the GPS constellation using the Architecture Evolution Plan, including a recent $105 million Lockheed Martin award to extend it for current satellites and the coming GPS IIIF batch.
  • RTX said it delivered OCX in 2025 and will keep working with the government on next steps.
