WASHINGTON — The Pentagon awarded RTX a $45.3 million contract modification to support U.S. military GPS satellite ground operations, sustaining critical space infrastructure while defense officials weigh scaling back the troubled Next Generation Operational Control System (OCX) program.
The one-year agreement ensures the U.S. Space Force maintains the capability to launch, check out, and operate highly advanced GPS space vehicles. This specifically includes the imminent deployment of SV-10, the tenth satellite in the modernized GPS III constellation, which is scheduled for launch later this month.
Issued as an “unpriced change order,” the modification authorizes RTX—formerly Raytheon Technologies—to proceed with urgent operational tasks before final costs are formally negotiated. This allows the government to maintain launch schedules while continuing to reassess the broader OCX program.
Reassessing a Troubled Ground System
The recent contract arrives amid strong indications that the Defense Department is preparing to pivot away from the full-scale development of OCX. The software program has been plagued by years of schedule delays, technical hurdles, and ballooning costs.
Over the past 15 years, the Pentagon has awarded Raytheon nearly $4.6 billion to develop the OCX architecture. The system was originally envisioned as a comprehensive replacement for legacy ground control stations, designed to bring space operations into the modern era.
Military planners initially designed OCX to provide robust, enhanced cybersecurity protocols and full command-and-control capabilities for the modernized GPS III satellites. It was also intended to fully enable the military’s advanced, jam-resistant M-code signals, which are vital for operations in contested electronic warfare environments.
However, the Pentagon is now limiting Raytheon’s current scope of work strictly to near-term support functions. The primary focus remains on launch and early orbit operations for the upcoming GPS III satellites.
According to officials familiar with the contract structure, this latest $45.3 million award deliberately excludes further software fixes, system tests, and transition-to-operations work tied to the broader OCX baseline. Instead, it gives the government critical flexibility to negotiate how elements of OCX could be incorporated into existing systems.
The Rise of the Architecture Evolution Plan
As OCX development stalled over the past decade, the military was forced to find alternative methods to operate its newest space assets. In 2016, the Air Force hired Lockheed Martin to upgrade the existing legacy ground system, known as the Architecture Evolution Plan (AEP).
This contingency measure was initially conceived as a temporary stopgap to ensure the multi-billion-dollar GPS III satellites could be operated upon reaching orbit. Over time, continuous upgrades and accumulating improvements have transformed the AEP into a highly viable, long-term operational alternative.
Currently, an early, limited version of OCX is utilized for the launch and early orbit checkout phases of GPS III satellites. However, this early iteration lacks the capacity to provide full, sustained command-and-control capabilities for the constellation.
Defense officials are now actively evaluating a hybrid approach. Rather than pushing the delayed OCX system to the finish line, the Space Force is considering harvesting fully functional, usable software components from the OCX program.
These extracted Raytheon-developed components would then be integrated directly into the existing Lockheed Martin-managed AEP baseline. This strategy aims to salvage portions of the $4.6 billion investment while prioritizing immediate operational readiness and network security.
Leadership Acknowledges Technical Hurdles
Senior military leaders are openly acknowledging the strategic pivot and the necessity of addressing the ground segment bottleneck. The Global Positioning System remains a critical backbone for both global commerce and precision military operations, making ground control just as vital as the satellites in orbit.
Chief of Space Operations Gen. Chance Saltzman recently confirmed that both the Department of the Air Force and the Office of the Secretary of Defense are conducting a comprehensive review of their ground control options.
“We have a serious issue, and that serious issue is being addressed,” Saltzman stated during the Mitchell Institute’s Spacepower Conference on April 1. His comments highlight a growing recognition within the Pentagon that ground systems often become the Achilles’ heel of space procurement.
Saltzman emphasized that the military is carefully evaluating both current capabilities and future requirements. “We’re looking at the existing systems. We’re looking at the future systems, how far do we go with it,” he noted.
The Chief of Space Operations further stressed that as more GPS III and subsequent next-generation satellites are launched into orbit, continuous upgrades to the ground control architecture will be mandatory. This requirement stands regardless of which specific software path the Pentagon ultimately chooses.
Strategic Implications and Next Steps
The strategic use of an unpriced change order highlights the urgency of maintaining the GPS III launch schedule while giving the government critical negotiating leverage. This specialized contracting mechanism avoids prolonged negotiations that could delay the SV-10 launch, while buying time to restructure the overarching ground segment strategy.
By freezing further OCX software development and focusing purely on launch support, the Pentagon is signaling a broader shift in space acquisition strategy. The military is increasingly favoring agile, modular upgrades to proven legacy systems over massive, monolithic software development programs.
Moving forward, the defense industry will closely watch how the Space Force navigates the complex integration of Raytheon’s OCX software fragments into Lockheed Martin’s AEP infrastructure. The success or failure of this software integration will heavily influence future Department of Defense procurement models.
Industry stakeholders should anticipate future ground system contracts to prioritize interoperability, open architectures, and incremental capability deliveries over high-risk, all-encompassing system overhauls. As the Space Force finalizes its assessment, the upcoming SV-10 launch will serve as a critical test of this transitional ground control strategy.
