The sudden intensity around cislunar security in U.S. defense circles is not random. It is the product of a deliberate policy shift, accelerating Chinese activity, and the belated recognition that the United States is effectively blind in a vast new domain that is about to become crowded.
Cislunar space—the volume stretching from beyond geostationary orbit out to the Moon and its vicinity—is more than a thousand times larger than the region enclosed by GEO. Existing ground-based radars and most space-surveillance sensors cannot maintain continuous custody of objects out there. For decades this did not matter; traffic was sparse and almost entirely scientific. That assumption has collapsed.
Two developments drove the change in 2025–2026. First, the Trump administration’s executive order on space superiority explicitly extended the military’s area of responsibility from low Earth orbit all the way through cislunar space and called for the ability to detect, characterize, and counter threats across that entire span. Senior leaders followed with unusually direct language. The Chairman of the Joint Chiefs stated that the joint force must be prepared to fight “from the seabed to cislunar space.” U.S. Space Command’s chief scientist listed cislunar and xGEO operations—including eventual offensive space control—among the command’s top science-and-technology priorities. The Space Force stood up a Cislunar Coordination Office and assigned existing squadrons to the mission.
Second, China is moving faster than many in Washington expected. Beijing is flying lunar missions, operating relays in exotic orbits, and advancing plans for an International Lunar Research Station with Russia and other partners. Chinese officials have spoken of the Moon in territorial terms that echo their approach to the South China Sea. From certain cislunar vantage points it is theoretically possible to observe or even threaten satellites in geosynchronous orbit with little warning, because the geometry and the sheer volume of space make continuous tracking extremely difficult. U.S. programs intended to close that awareness gap—most notably the Oracle spacecraft—have slipped, leaving a coverage hole precisely as traffic is projected to rise with Artemis, commercial landers, and resource prospecting.
The strategic logic is straightforward and familiar: flag follows trade. As civil and commercial activity expands toward the Moon, the military argues it must be able to protect freedom of action, provide positioning and timing where GPS does not reach, maintain domain awareness, and, if necessary, conduct space-control operations. The alternative, in this view, is to let China set the norms and occupy the key locations first.
That combination—an explicit presidential directive, senior uniformed leaders speaking publicly about fighting near the Moon, institutional reorganization inside the Space Force, delayed sensors, and visible Chinese progress—explains why cislunar security moved from niche academic papers to a stated priority in a relatively short time. The domain itself has not suddenly become more valuable; the United States has simply decided it can no longer afford to treat it as an afterthought.
The Race to Secure Cislunar Space
To bridge the massive domain awareness gap beyond geostationary orbit, the Pentagon and the U.S. Space Force are rapidly moving from theoretical frameworks to hard contracts, fueling a commercial gold rush to build the infrastructure of deep-space military operations. At the forefront of this mobilization is the need for persistent tracking and sensing. Aerospace giants and agile startups are competing to build the eyes and ears of cislunar space. Companies like ExoAnalytic Solutions and Advanced Space are already pioneering specialized space domain awareness architectures. Advanced Space’s CAPSTONE spacecraft demonstrated the viability of unique lunar orbits, while prime contractors like Northrop Grumman and Lockheed Martin are actively designing highly sensitive optical and radar networks capable of spotting dark, non-reflective objects across hundreds of thousands of miles of void. These sensors will feed directly into the U.S. Space Force’s upcoming Oracle architecture, formerly known as CHPS, a dedicated satellite mission designed specifically to detect and track anomalies in the gravitational wild west of the Earth-moon libration points.
Sensing the domain is futile without the ability to navigate it, making the race for Position, Navigation, and Timing (PNT) infrastructure the next critical battleground. The traditional GPS network degrades severely past geostationary altitudes, forcing the military to seek deep-space alternatives. Companies like Blue Origin, through its space systems division, and specialized communications firms are competing to establish commercial lunar constellations that will pull double duty, serving both civilian miners and military patrollers. Parallel to these efforts, the Defense Advanced Research Projects Agency (DARPA) is pushing forward with its LunA-10 capability study, aiming to integrate PNT, power, and communications into a single, scalable commercial framework. This commercial backbone will ensure that military interceptors and reconnaissance craft can calculate precise trajectories around the moon without relying on laggy, Earth-based tracking stations.
While defense officials publicly emphasize surveillance and logistics, the quiet development of space control capabilities—or space weapons—is accelerating. Securing the domain requires the ability to neutralize threats, leading to conceptual designs for high-powered directed-energy weapons, electronic warfare jammers to sever lunar communications, and highly maneuverable kinetic interceptors. Because the physics of cislunar space allow objects to “hide” in complex multi-body orbits before diving toward a target, future space weapons will likely focus on rapid-response co-orbital interceptors capable of loitering in Lagrange points for months before activation. Startups specializing in autonomous orbital refueling and in-space servicing, such as Orbit Fab, are suddenly finding themselves reclassified as critical national security assets, as their “gas stations in space” will dictate which military can sustain a fleet of weapons platforms in the deep lunar theater.
China will not watch this American mobilization in isolation; Beijing is already executing a sophisticated, parallel counter-strategy. The Chinese National Space Administration and the People’s Liberation Army are leveraging their own deep-space network, anchored by the Queqiao relay satellites, to establish a permanent operational foothold. Beijing views American cislunar dominance as an existential threat to its own lunar ambitions and will likely respond by deploying its own defensive counter-space architectures. We can expect China to establish “exclusion zones” around its planned International Lunar Research Station under the guise of safety, backed by ground-based lasers and co-orbital inspection satellites designed to blind or disable approaching Western sensors. The resulting friction will transform the lunar poles into a geopolitical chessboard, where both superpowers utilize aggressive close-approach maneuvers to test each other’s rules of engagement in a zone devoid of international maritime law.
As the race to industrialize the moon heats up in parallel, the line between commercial resource extraction and military dominance will blur entirely. The discovery of volatile water ice in the permanently shadowed craters of the lunar south pole has made ice the new oil. The nation that controls and processes this ice into hydrogen fuel will control the logistics network of the entire solar system. Consequently, space militaries will rapidly expand their reach from passive monitoring to active asset protection. Future lunar industrial complexes—comprising automated ice miners, regolith processors, and landing pads built by companies like Intuitive Machines and SpaceX—will require dedicated military escorts. We can expect the emergence of a “Space Coast Guard” doctrine, where military or paramilitary spacecraft patrol commercial shipping lanes between Earth and the moon, enforcing property rights, deterring state-sponsored sabotage, and ensuring that the economic engine of the next century remains firmly under their respective sphere of influence.
Who wouldve guessed defunding space research and exploration and exporting it to for profit companies will lead to a loss of ground in that sector.
