The U.S. Space Force reports that its satellites experience jamming, dazzling, or other hostile electronic interference on a daily or near-daily basis. Not occasionally. Not during heightened tensions. As a routine operational reality, every day, somebody—and the “somebody” is almost always China or Russia—is attempting to degrade, disrupt, or blind American space-based assets. GPS signals are spoofed. Communications links are jammed. Sensor systems are targeted with directed-energy weapons designed to temporarily overwhelm their optics. None of this involves explosions. None of it generates debris. None of it makes the news. And all of it is, by any functional definition, warfare—conducted in orbit, against military infrastructure, by state actors with the explicit goal of degrading an adversary’s capability.
Space warfare isn’t coming. It’s here. It just doesn’t look like Star Wars. It looks like an electromagnetic interference report filed by a satellite operations center in Colorado Springs at 3 AM on a Tuesday, which is less cinematic but considerably more consequential.
Why space matters militarily (the version nobody skips)
Every precision-guided munition the U.S. military fires depends on GPS satellites for navigation. Every drone feeds its sensor data through satellite communications links. Every early-warning system that detects a ballistic missile launch does so with space-based infrared sensors that spot the thermal signature of a rocket plume within seconds of ignition. Every intelligence assessment of enemy force disposition relies on satellite imagery. The U.S. military doesn’t just use space—it is architecturally dependent on space in a way that no other military in history has been dependent on a single domain.
This creates an asymmetry that China and Russia have studied carefully and concluded is a vulnerability worth exploiting. If you can deny an adversary access to its space-based assets—its GPS, its communications, its surveillance, its missile warning—you don’t have to match it capability-for-capability on the ground, at sea, or in the air. You just have to blind it. A carrier strike group without satellite communications and GPS-guided weapons is a very expensive collection of ships that can’t coordinate, can’t navigate precisely, and can’t hit anything beyond visual range. The entire American way of war since the first Gulf War has been built on the assumption that space-based services will be available, uninterrupted, when needed. That assumption is now the single most attractive target in the U.S. military architecture.
What countries are actually doing
The Secure World Foundation’s 2025 Global Counterspace Capabilities report—the publication of record on this topic—documents counterspace programs in 12 countries. The three that matter most are China, Russia, and the United States, though India, France, Japan, and others are developing capabilities.
China conducted a direct-ascent anti-satellite missile test in 2007, destroying one of its own defunct weather satellites at an altitude of roughly 865 kilometers. The test was a technical success and a diplomatic disaster—it created nearly a thousand pieces of trackable debris, much of which is still in orbit and will remain there for decades, endangering every satellite in that altitude band including China’s own. The test was not a surprise to U.S. intelligence, which had been warning since 2003 that Beijing was developing this capability. What it demonstrated was intent: China was willing to create a permanent debris hazard in its own operating environment to signal that it could kill satellites.
Since then, China has moved significantly beyond kinetic kill vehicles. Its military now operates satellites capable of what the Space Force calls “dogfighting”—maneuvering in proximity to other nations’ satellites, inspecting them, and potentially grabbing them and dragging them into graveyard orbits. The Secure World Foundation documented five Chinese satellites conducting rendezvous and proximity operations throughout 2024. China routinely employs ground-based jammers targeting satellite communications, radar, and navigation systems, including the Pentagon’s extremely high-frequency systems. Ground-based lasers capable of dazzling or damaging satellite optical sensors are in development and could be deployed before the end of the decade. China’s operational satellite fleet exceeded 1,060 by mid-2025, with hundreds dedicated to intelligence, surveillance, and reconnaissance—building what Space Force leadership describes as a “kill web” that uses hundreds of satellites to find, track, and target forces on Earth.
Russia has its own portfolio. The Peresvet, a ground-based high-energy laser system deployed with mobile ICBM units, is designed to dazzle the optical sensors of reconnaissance satellites that would otherwise track Russia’s nuclear missile launchers. Russia has demonstrated co-orbital anti-satellite capability through its Luch satellite program, which has conducted proximity operations against Western communications satellites in geostationary orbit. In November 2021, Russia conducted a direct-ascent ASAT test against one of its own satellites, creating over 1,500 pieces of trackable debris and forcing the International Space Station crew to shelter in their evacuation vehicles. The test drew universal condemnation, including from China.
The most alarming Russian development, however, is the reported nuclear anti-satellite weapon. U.S. intelligence confirmed in February 2024 that Russia is developing a satellite designed to carry a nuclear warhead into orbit—not to use against targets on Earth, but to detonate in space and destroy or disable satellites across a wide orbital zone through electromagnetic pulse. A nuclear detonation in low Earth orbit would be indiscriminate—it would fry not just American military satellites but commercial satellites, allied satellites, and Russian satellites. It would generate an EMP across hundreds of kilometers of orbital altitude, potentially rendering entire orbital shells unusable. The Outer Space Treaty of 1967 explicitly prohibits placing nuclear weapons in orbit. Russia ratified that treaty. Whether that matters in practice is a question the treaty wasn’t designed to answer.
The United States has historically been more circumspect about its offensive space capabilities—which, given the classification levels involved, means we know less about what the U.S. can do than what China and Russia can do. What’s publicly known: the Space Force operates the GSSAP (Geosynchronous Space Situational Awareness Program) satellites, which conduct proximity operations in geostationary orbit and are officially described as a “neighborhood watch,” though their maneuvering capabilities are consistent with inspection and potentially interference missions. The X-37B, an autonomous reusable spaceplane operated by the Space Force, has completed multiple extended missions in orbit—the most recent lasting over 900 days—with mission objectives that remain classified. The Space Force announced in early 2026 that it is deploying three electronic satellite jammers, the first acknowledged offensive counterspace weapons in the U.S. arsenal. Under the Trump administration’s “Golden Dome for America” missile defense initiative, boost-phase interceptor prototypes—weapons designed to destroy enemy ballistic missiles from space during the first minutes of flight—were awarded under competitive contracts in late 2025.
Space Force Chief of Space Operations General Chance Saltzman has been remarkably direct about where this is heading. At the Air and Space Forces Association Warfare Symposium in March 2025, he declared that the Space Force “will do whatever it takes to achieve space superiority.” In testimony before the U.S.-China Economic and Security Review Commission, he described the need to develop systems that can deny China’s use of its space assets—not just protect American satellites, but actively degrade an adversary’s space architecture. That’s a significant escalation in stated policy from “protect our stuff” to “break their stuff.”
The Kessler problem
Every kinetic anti-satellite test—every satellite physically destroyed in orbit—generates debris that travels at orbital velocity (roughly 28,000 kilometers per hour in low Earth orbit) and remains in orbit for years to decades depending on altitude. A bolt traveling at that speed carries the kinetic energy of a hand grenade. The four countries that have conducted destructive ASAT tests—the U.S., Russia, China, and India—have collectively created 6,851 catalogued pieces of trackable debris, of which 2,920 are still in orbit as of the 2025 Secure World Foundation report.
The Kessler syndrome, proposed by NASA scientist Donald Kessler in 1978, describes a scenario in which the density of debris in orbit becomes high enough that collisions between objects generate more debris, which causes more collisions, in a cascading chain reaction that eventually renders entire orbital shells unusable. We’re not there yet. But every destructive ASAT test moves the needle closer, and the 2007 Chinese test and 2021 Russian test together represent the two largest single contributions to the orbital debris environment in history.
This is why the Space Force publicly states that kinetic destruction of enemy satellites is a last resort—the debris affects everyone, including the country that created it. The preferred tools are reversible: jamming, spoofing, dazzling, cyber intrusion. Blind the satellite temporarily rather than blow it up permanently. The problem is that “reversible” tools don’t provide the deterrent clarity that “we destroyed your satellite” does, which creates a strategic ambiguity that makes escalation management in space considerably harder than it is in other domains. If someone jams your satellite and then stops, was that an act of war or a provocation? The answer matters, and nobody has established the norms to answer it.
Starlink changed the equation
The war in Ukraine demonstrated something that military planners had theorized but never seen in practice: a commercial satellite constellation can provide militarily critical communications capability that is extraordinarily difficult to destroy. Ukraine’s military used Starlink extensively for battlefield communications, drone coordination, and command-and-control functions. Russia attempted to jam it. The jamming had some effect—there were reports of service interruptions—but the constellation’s architecture made it resilient. Starlink operates thousands of small satellites in low Earth orbit, and destroying enough of them to meaningfully degrade the network would require an anti-satellite campaign of a scale that nobody has the inventory to conduct.
SpaceX subsequently developed Starshield, a version of Starlink designed specifically for national security applications, with enhanced encryption and anti-jamming features. The lesson that every military in the world drew from Ukraine was that proliferated constellations of small, cheap, replaceable satellites are dramatically harder to kill than traditional military satellites—large, expensive, few in number, and each representing a single point of failure. The Space Development Agency’s Tranche 3 tracking layer, a $3.5 billion investment for 72 new satellites awarded in late 2025, reflects this shift: distribute capability across many platforms so that losing any one of them doesn’t cripple the network.
Where this goes
The Space Force’s “Race to Resilience” initiative aims to achieve battle-ready space architectures by 2026—meaning satellite constellations that can absorb attacks and continue functioning, with the ability to reconstitute lost capability by launching replacement satellites on short notice. Four on-orbit servicing demonstrations are planned for 2026 to test satellite refueling, repair, inspection, and maneuvering—capabilities that are defensive in framing but dual-use in practice, because a satellite that can refuel a friendly satellite can also approach and interfere with a hostile one.
Germany committed 35 billion euros to low-Earth-orbit resilience and non-kinetic deterrence in early 2026. The U.S. Congress appropriated $250 million specifically for directed energy research and development that includes space-based applications. The Golden Dome initiative is exploring space-based missile interceptors. The trajectory is unmistakable: space is being weaponized, the major powers are building the tools to fight there, and the governance framework—the Outer Space Treaty, written in 1967 when the total number of objects in orbit could be counted in the hundreds—is not remotely equipped to manage a domain that now contains over 10,000 active satellites and is the operational backbone of every advanced military on the planet.
The conflict in space won’t look like a battle. It’ll look like a degradation—GPS accuracy declining by meters, then tens of meters, then failing entirely. Satellite imagery going dark over a region at the worst possible moment. Communications links dropping during a crisis. Early warning systems providing ambiguous data when clarity matters most. The weapons are invisible, the effects are deniable, and the consequences are catastrophic. That’s not a future scenario. Portions of it are happening right now, in orbit, every day, and the people tasked with responding to it are working out of a military branch that’s younger than most TikTok accounts.
We cover space warfare—alongside drones, directed energy weapons, electronic warfare, autonomous systems, and every other technology reshaping combat from 2025 to 2125—across 36 lectures in our Battlefields of the Future course. If the daily jamming reports or the nuclear ASAT program changed your mental model of what’s happening in orbit, that’s where the full picture lives.
