The US Space Force is considering canceling the $8 billion GPS Next-Generation Operational Control System program after RTX Corporation failed to resolve persistent technical issues following years of delays.

Key points

• The GPS Next-Generation Operational Control System (OCX) has seen its costs balloon from an initial $3.7 billion estimate in 2010 to approximately $8 billion today.
• Despite the Space Force accepting delivery of the system last July, extensive testing revealed unresolved software defects and systemic issues across all subsystems.
• The program was intended to manage advanced GPS III satellites and jam-resistant "M-code" signals, which are critical for modern military navigation and defense against spoofing.
• The Pentagon is now evaluating whether to abandon the OCX program entirely and continue upgrading the military's aging legacy ground control system instead.
• Government Accountability Office reports previously cited poor acquisition decisions, inadequate software expertise, and persistent engineering failures as primary drivers of the program's decline.

The potential cancellation of OCX highlights significant vulnerabilities in the military's ability to modernize critical infrastructure against increasing global threats like GPS jamming and spoofing. If the program is scrapped, the military must rely on legacy systems, which could limit the effectiveness of advanced weapons platforms that depend on next-generation navigation signals.
