The U.S. Air Force has assumed control of the long-troubled M-Code military GPS receiver program, taking over a sprawling modernization effort aimed at equipping ships and aircraft with jam- and interference-resistant positioning capability. The handover, reported by SpaceNews on July 24, extends the Air Force's authority to include both MGUE Increments 1 and 2 as well as the aviation-receiver programs that depend on that underlying technology.
Despite the program's troubled history, progress appears to be accelerating. According to Breaking Defense, testing of M-Code receivers for naval and aviation platforms is now on track to conclude by 2027 — a meaningful milestone for a program that has faced years of delays★. M-Code is specifically designed to resist jamming and interference, addressing one of the more pressing vulnerabilities in GPS-dependent military operations at a time when adversaries are investing heavily in electronic warfare.
Showing Congress What Space War Looks Like
Running alongside the GPS modernization push is a separate but thematically linked effort by the Space Force Association's National Spacepower Center to build an unclassified environment where satellite threats — and their downstream effects on Earth-based operations — can be demonstrated to policymakers. SpaceNews reported on July 31 that the center is specifically focused on making the abstract stakes of space warfare legible to members of Congress who do not routinely receive classified briefings★.
The effort moved from concept to demonstration on July 21, when the National Spacepower Center and its consortium partners — Redwire, COMSPOC, Sedaro, OpenC3, and TigerVision — presented an integrated pilot demonstration to Chief of Space Operations Gen. B. Chance Saltzman. The presentation marked the first time the group had shown a fully integrated prototype to Space Force leadership.
Together, the two developments reflect a broader institutional reckoning with how dependent U.S. military command-and-control has become on space-based systems, and how exposed those systems remain to adversarial interference. Hardening the GPS signals that ships and aircraft rely on addresses one layer of that vulnerability; persuading Congress of the urgency addresses another. Whether either effort moves fast enough to match the pace of adversary capability development remains an open question.
