The US and China Are Turning Orbit Into a Battlefield

The United States and China are rapidly developing military capabilities that could turn Earth’s orbit into a new arena of strategic competition. From manoeuvrable satellites to secretive spaceplanes and systems designed to interfere with or disable spacecraft, both powers are preparing for a conflict in which control of space could become as important as control of land, sea and air.

The shift is visible in the behaviour of satellites themselves. In June, a secretive Chinese unmanned spaceplane released a small satellite hundreds of miles above Earth. According to US space-tracking company LeoLabs, the object manoeuvred around another Chinese satellite before moving back towards the spaceplane. The exact purpose of the mission remains unclear, but the ability to approach and manoeuvre around another spacecraft is precisely the type of capability that military planners are increasingly watching.

China is developing a broader ecosystem of technologies around this concept. Researchers linked to the Chinese military are working on satellites capable of pursuing and potentially capturing other spacecraft, as well as systems that could extend their operational range by providing additional fuel in orbit. Such technologies could eventually allow satellites to inspect, disrupt, move or disable other spacecraft without relying on traditional missiles.

The United States is pursuing similar capabilities. Its military operates an unmanned spaceplane of its own, while the US Space Force is expanding its ability to monitor and respond to activity in orbit. Washington and London have also conducted what commercial tracking data indicates was their first joint military operation in space, near a satellite suspected by the US and its allies of conducting intelligence activities.

From satellites to space combat systems

For decades, satellites were primarily treated as infrastructure supporting warfare on Earth. They provided communications, navigation, weather data and intelligence while remaining largely passive objects following predictable orbital paths.

That assumption is disappearing.

Modern military planners increasingly see satellites as manoeuvrable assets that can actively interfere with an adversary. Jamming can disrupt communications. Lasers can temporarily blind sensors. More sophisticated systems could physically approach another spacecraft, inspect it, interfere with its operation or potentially capture it.

This creates a fundamentally different security environment. A satellite no longer has to be destroyed to become useless. It can be blinded, jammed, displaced or otherwise compromised while remaining physically intact.

The implications extend far beyond space itself. Modern armed forces depend on satellites for intelligence, communications, navigation and missile-warning systems. A serious disruption of those networks could degrade military operations across every other domain. US military officials have therefore warned that Chinese and Russian capabilities designed to interfere with or destroy American space assets represent a major strategic threat.

The orbit is becoming crowded

The strategic competition is unfolding as Earth’s orbit becomes increasingly congested.

Commercial satellite constellations are expanding rapidly, putting thousands of spacecraft into increasingly valuable orbital regions. That creates both economic opportunities and new vulnerabilities. Military systems now operate alongside commercial communications, Earth-observation and navigation infrastructure, making it increasingly difficult to separate civilian and military space activity.

This also changes the potential consequences of a conflict. An attack on one military satellite could generate debris capable of threatening other spacecraft, including commercial systems belonging to countries that are not directly involved in the confrontation.

The result is a security environment in which escalation could spread far beyond the original target.

A different kind of arms race

The US-China competition is therefore not simply another race to build more powerful weapons. It is a race to develop the ability to operate persistently in an environment where distance, speed and manoeuvrability determine strategic advantage.

Spaceplanes are particularly important because they combine some of the characteristics of spacecraft and aircraft. They can manoeuvre, carry payloads and potentially deploy or recover other objects. To an adversary, their exact mission may be difficult to determine, creating uncertainty at precisely the moment when military decision-making depends on knowing what another state is capable of doing.

China's progress is attracting increasing concern in Washington. US Space Force Chief of Space Operations General Chance Saltzman said in July that Beijing was rapidly developing ground- and space-based systems designed to interfere with or destroy targets, describing the Chinese threat as substantial.

For Europe, the strategic lesson is broader than the competition between Washington and Beijing. European security increasingly depends on space infrastructure, while European countries remain heavily reliant on allied capabilities for military intelligence, navigation and secure communications.

The next generation of warfare may therefore begin before a missile is launched or a fighter takes off. It may begin with a satellite changing its orbit, approaching another spacecraft or silently disrupting the systems that armies on Earth depend on.
