The U.S. Space Force has reportedly awarded Lockheed Martin a contract to manage ground control operations for the next generation of GPS satellites, a decision that amounts to an institutional admission: the Pentagon’s long-troubled OCX program cannot do the job it was built to do.

The award covers launch, early orbit, and disposal operations for GPS IIIF satellites, using the existing Architecture Evolution Plan (AEP) ground control system rather than the Next Generation Operational Control System that was supposed to replace it. The contract puts Lockheed Martin back in the driver’s seat of GPS ground operations, a position RTX (formerly Raytheon) was meant to claim when it won the OCX contract over a decade ago.

What the Contract Actually Does

The Space Force’s contract covers the Architecture Evolution Plan operational control system to support launch, early orbit and disposal operations for Global Positioning System IIIF space vehicles. That language is dry and bureaucratic. Its implications are not.

GPS IIIF represents the newest tranche of navigation satellites the military plans to put in orbit, with launches expected to begin next year. The ground control system for those satellites was supposed to be OCX. Instead, the Pentagon is betting on AEP, a legacy system that Lockheed Martin has been upgrading in recent years as OCX’s schedule slipped further and further to the right.

That decision was originally framed as a stopgap. AEP would handle GPS III operations temporarily while OCX matured. But a stopgap that persists for years and gets expanded to cover the next generation of satellites is no longer a stopgap. It is the plan.

The OCX Program: $8 Billion and Counting

The OCX story is one of the most expensive cautionary tales in modern defense acquisition. Raytheon won the Pentagon contract in the early 2010s to build a next-generation ground control system for GPS. It was supposed to cost under $4 billion and be finished within several years. As of early 2026, the official cost stands at $7.6 billion, with additional augmentation projected for GPS IIIF support, pushing the total past $8 billion.

The system is designed to command and control the military’s constellation of more than 30 GPS satellites, including software for new signals and jam-resistant capabilities that newer GPS III satellites offer. It encompasses two master control stations and upgrades to monitoring stations worldwide.

RTX delivered OCX to the Space Force in mid-2025, which was supposed to mark a turning point. Military teams would validate the software and upgraded facilities, then declare the system ready for operational service. That validation process uncovered more problems. Military officials told Congress recently that OCX is still struggling, according to Ars Technica’s reporting.

Months after delivery, the system remains nonoperational.

Seven Years Behind, and the Clock Is Still Running

The Government Accountability Office has tracked OCX’s trajectory with increasing alarm. According to reporting, the program is approximately seven years behind the original schedule, and its ground network was not ready by deadlines in 2024. The GAO has flagged the program’s delays as a direct risk to the broader GPS enterprise.

Lawmakers have expressed frustration repeatedly. The pattern is familiar to anyone who watches defense procurement: a technologically ambitious program runs into software development problems, the schedule slips, costs rise, Congress holds hearings, the contractor receives extensions, and the cycle continues.

What makes the GPS ground system story different from many troubled programs is that the military had a fallback. AEP already existed. Lockheed Martin already operated it. When OCX fell behind, upgrading the legacy system was a viable alternative because the institutional infrastructure was already in place. That option gave decision-makers an exit ramp they are now clearly taking.

RTX Gets a Smaller Piece

The Lockheed Martin contract does not entirely shut RTX out of the GPS ground segment picture. The Pentagon also reportedly awarded RTX a contract modification for OCX Block 0, which covers support for the final GPS III satellite launch and an assessment of how parts of OCX could be integrated into AEP.

That modification tells its own story. The Pentagon appears to be salvaging what it can from OCX, extracting useful elements and folding them into the system that actually works, rather than continuing to fund a standalone program that has not delivered operational capability after years of development.

The integration assessment is the key detail. If some OCX components can be absorbed into AEP, the military might recover a fraction of its investment in capabilities like M-Code support, which provides jam-resistant GPS signals for military operations in contested environments. But the framing has shifted. OCX is no longer the destination. It is a parts bin.

Why This Matters Beyond GPS

GPS is not just a military navigation tool. Civilian infrastructure across the United States and globally depends on GPS timing signals for everything from financial transactions to power grid synchronization to air traffic management. The ground control system that commands and manages the satellite constellation is the backbone of that entire architecture.

The decision to use a proven, upgraded legacy system rather than a troubled next-generation replacement reflects a pragmatic calculation that reliability matters more than technical ambition when the stakes are this high. AEP may not have all the features OCX promised, but it works. For a constellation that underpins vast amounts of economic activity, “works” counts for a great deal.

Lockheed Martin, which has been building and supporting GPS ground infrastructure for decades, re-emerges as the dominant contractor in this space. The company has been expanding its role across military satellite programs, and the GPS IIIF ground control contract reinforces that position.

The Institutional Incentive Problem

The OCX saga raises uncomfortable questions about how the Pentagon manages large software-intensive programs. The original contract was awarded in the early 2010s during a period when the Defense Department was attempting to modernize several major space ground systems simultaneously. The assumption was that a clean-sheet software architecture would deliver better performance than incremental upgrades to legacy systems.

That assumption proved wrong, at least in this case. The reasons are multiple and overlapping: software complexity was underestimated, cybersecurity requirements grew significantly during development, the contractor struggled with integration testing, and oversight mechanisms failed to force course corrections early enough.

But there is a structural incentive problem as well. Once a program reaches a certain size and has enough political constituencies invested in its continuation, killing it becomes harder than funding it. The Space Force’s GPS ground system had to reach a point where the alternative was not only available but clearly superior before the institution could justify the pivot.

That point appears to have arrived. The Lockheed Martin contract is not just a procurement action. It is the Pentagon’s way of saying: we tried the ambitious path, it did not work, and we are going with what does.

Whether the OCX integration assessment produces anything useful, or whether the program’s technical contributions get quietly shelved alongside its $8 billion price tag, will be worth watching over the next few years. For now, the legacy system has won. The next-generation replacement became the thing it was supposed to replace: obsolete before it was operational.
