Three nuclear powers now run military command on the same commercial satellites that route your Uber. A space nuclear detonation could wipe out orbital satellites within months, causing 3 trillion in damage. The Air Force is spending 68 million to study it.
Three nuclear powers are now running military command on the same commercial space infrastructure that timestamps your bank transfers, synchronizes power grids, and routes your delivery apps. The firewall between civilian and military space is gone, Marcus Lewis, a defense policy analyst, wrote in a SpaceNews op-ed published this week, and no treaty in existence covers what happens when you attack the civilian half of that merged system. The operational evidence for why that matters is already playing out: in the Iran conflict earlier this year, U.S. forces struck roughly 2,000 targets in four days using AI-enabled systems, and Israeli forces devoted roughly 20 seconds to validating each AI-flagged target before launch.
The pattern Lewis identified is not new. SIPRI published a paper on space systems integration into nuclear deterrence in 2023. The Atlantic Council wrote an issue brief on it in 2024. But what Lewis did was name the convergence plainly: the same GPS constellation that lets your phone navigate also runs nuclear timing signals, the same commercial satellite networks that carry video calls also relay battlefield data, and the policy frameworks written to manage nuclear risk were designed for a world where those two systems were separate.
The mechanism is JADC2, the Pentagon program that connects sensors and shooters across all military domains into a common operating picture. Budget documents make clear that JADC2 and NC3 must be developed in synchronization, even as policymakers debate exactly how tightly they should be coupled. Lt. Gen. Andrew J. Gebara, the Air Force deputy chief of staff for strategic deterrence and nuclear integration, described the shift in an interview with Air and Space Forces Magazine: the old model of completely separate NC3 from conventional command and control is gone, and the services need to use the benefits they are gaining out of joint all-domain command control.
The GPS Next-Generation Operational Control System illustrates the infrastructure problem. The replacement software does not fully work. The program has consumed roughly $8 billion over 16 years and is now a decade past its original 2016 deadline, The Meridiem reported March 31, citing Wired. The control system for the world's most critical navigation and timing infrastructure is broken, and it is now part of the same architecture that runs nuclear command.
The dual-use nature of the underlying constellations compounds the exposure. GPS timestamps nearly every financial transaction on earth, synchronizes power grids, and routes rideshare apps. The Space-Based Infrared System and Defense Support Program were launched to detect missile launches. They now also detect wildfires and volcanic eruptions through their thermal signatures. Any conflict that threatens GPS is already catastrophic by any reasonable definition.
China is building the same architecture through a different institutional path. Military-Civil Fusion, the policy that integrates dual-use civilian technologies into the People's Liberation Army, means BeiDou navigation satellites and Yaogan remote-sensing spacecraft serve both commercial customers and nuclear command. Russia is doing the same with GLONASS. The three nuclear powers are converging on the same structural model, and none of their arms control treaties were written to see it.
Gen. B. Chance Saltzman, chief of U.S. Space Operations, asked the question directly in an Atlantic Council paper published last year: if nuclear command is spread across 400 satellites, how many must be shot down to take out U.S. nuclear command and control? The answer under the hybrid model is more than any adversary could realistically target in a first strike, but fewer than it would take to destroy a purpose-built military constellation. The model is more resilient to accidental trigger-pull but more exposed to software failure, supply chain disruption, and the everyday entropy of commercial systems.
The most concrete physical risk is also the most underappreciated. A high-altitude nuclear detonation, a weapon exploded in space to disable adversary satellites, would raise radiation flux in the Van Allen belts by three to four orders of magnitude. Derek M. Tournear, director of the Space Development Agency, has said his organization's satellites will not be hardened against such an attack, only hardened sufficiently to ensure operational effectiveness in their orbits. Most low-Earth orbit satellites not specifically hardened could fail within weeks to months of such an event. Direct damages would probably approach $500 billion, with overall economic impact exceeding $3 trillion, from loss of GPS timing alone, which underpins financial markets, power grid synchronization, and mobile networks globally.
The policy gap is real. RAND, the Congressional Research Service, and the Center for Strategic and International Studies have all published reports flagging the structural exposure. SIPRI documented how the integration of space systems into nuclear deterrence creates new escalation pathways. Lewis's contribution is naming the pattern and calling the question. The frameworks for managing this exposure, Outer Space Treaty inspections, Incidents at Sea agreements, crisis communication channels, were designed for a world where nuclear command and commercial space were separate domains. The $68 million the Air Force has budgeted for research into commercial-based NC3 technologies suggests the military knows the problem exists. Whether the policy community can move before the infrastructure does is the open question.
