NATO fears Russia developing shrapnel-based anti-satellite weapon targeting Starlink

Intelligence officials from two NATO member states have concluded that Russia is likely developing a new kind of anti-satellite weapon, one designed to flood orbital space with shrapnel rather than strike individual targets. The suspected system would release hundreds of thousands of dense pellets into the paths where Starlink satellites operate, potentially disabling many of them at once. According to findings reviewed by the Associated Press, the weapon would use what analysts call a "zone-effect" approach—essentially turning an entire orbital region into a minefield of debris. The intelligence services involved did not allow themselves to be identified, and the AP noted it could not independently verify the conclusions.

Why Russia would pursue such a system is clear enough: Starlink has become critical infrastructure for Ukraine. Since Russia's full-scale invasion began four years ago, thousands of low-orbit Starlink satellites have provided high-speed internet to Ukrainian military units for communication, targeting, and coordination. Civilians and government officials also depend on the service when Russian strikes destroy ground-based networks. Moscow has made no secret of its view that commercial satellites supporting Ukraine's military are legitimate targets. This month alone, Russia announced the deployment of its S-500 missile system, which it claims can strike objects in low orbit. A shrapnel-based weapon would represent a far more ambitious escalation—one that could theoretically disable not dozens of satellites but hundreds or thousands.

The proposed system would differ fundamentally from Russia's 2021 anti-satellite test, in which a missile destroyed a single inactive Cold War-era satellite. Instead, small satellites not yet launched could release pellets just millimetres across, which would then orbit alongside active satellites, creating repeated collision risks. Brig. Gen. Christopher Horner, who leads Canada's military Space Division, compared the concept to exploding a container filled with ball bearings—the debris would threaten every satellite in the same orbital zone, regardless of its owner or purpose. The pellets would be so small that existing tracking systems would struggle to detect them, complicating efforts to quickly determine what had happened if satellites began failing.

Yet here lies the central paradox that has made experts deeply skeptical: such a weapon would be almost impossible to control, and its consequences would almost certainly harm Russia itself. Starlink operates at roughly 550 kilometres above Earth. China's Tiangong space station and the International Space Station orbit lower, but debris from a shrapnel attack would eventually spread, posing risks to all spacecraft in the region. Russia depends on satellites for communication, defence, and other critical functions. Any indiscriminate orbital weapon would be a potential self-inflicted wound. Victoria Samson, a space security expert at the Secure World Foundation, expressed strong doubt that Russia would actually deploy such a system. The risks of uncontrollable damage, she said, make the idea difficult to accept. She would be surprised if Moscow pursued it beyond research.

Military officials, however, caution against dismissing the possibility outright. Horner noted that if Russia is willing to explore highly destructive space systems—including, according to past US allegations, nuclear-based weapons—it would not be shocking if it also considered something slightly less extreme but still deeply damaging. The intelligence findings do not specify when the system could be deployed, whether it has been tested, or how far advanced the research actually is. An official familiar with the findings said only that the weapon remains in development and that timing details are too sensitive to disclose.

Samson suggested the research could be purely experimental, driven by scientists exploring theoretical possibilities rather than an imminent deployment plan. She also noted that such threats are sometimes raised to provoke international reactions or to justify increased spending on counter-space capabilities. Clayton Swope of the Centre for Strategic and International Studies offered another interpretation: the suspected system may function primarily as a "weapon of fear," designed to deter adversaries through the mere possibility of widespread orbital disruption, without ever needing to be used. The long-term consequences of deploying it would likely prevent its use, Samson concluded. Doing so would undermine Russia's own position as a space power, cutting off access to the very domain it has invested heavily to maintain. What remains unclear is whether Russia is genuinely developing a deployable weapon or signalling its capability to do so—and whether the distinction ultimately matters.
