Could Russia Be Poised to Use an On-Orbit Weapon Against a Commercial Satellite?

As of October 15, 2026, based on commercial space situational awareness data, a Russian satellite called Cosmos 2612 is on a trajectory that will bring it into very close proximity to a U.S.-registered commercial synthetic aperture radar (SAR) satellite. The satellite, which supports Ukraine, is operated by ICEYE, a company founded in Finland. Given Russia’s history of testing on-orbit weapons, policymakers should assume Cosmos 2612 could take an action that threatens the commercial satellite. But the risk extends beyond just one satellite. A Russian counterspace activity in the vicinity of Western satellites should be assessed within the context of aggressive Russian gray zone activities targeting U.S. and European interests. To date, neither the United States nor Europe has been able to deter Russia from expanding the scope and frequency of these gray zone actions. As Russia appears poised to increase hostile actions in outer space to test Western resolve, the United States and Europe should decide how they would respond to a hostile act in space and make that response clear.

In April 2026, Russia launched six satellites, Cosmos 2609 through Cosmos 2614, into low Earth orbit (LEO). A month later, five of the satellites executed high-energy maneuvers that raised their inclinations to match the orbital plane of the ICEYE satellite. These moves were unusual because satellites in LEO typically avoid plane-change maneuvers as they require a large amount of fuel. Several of these Cosmos satellites came near the commercial satellite in May 2026, with Cosmos 2609 getting closest on May 26, at just 2.5 kilometers away. However, none of the Cosmos satellites maneuvered during this period to stay plane-matched (or coplanar) with the ICEYE satellite, so their orbital planes slowly diverged. Then, over two weeks beginning on September 30, 2026, Cosmos 2612 executed a series of new maneuvers that brought it back into coplanar alignment and placed it at nearly the same altitude as the commercial satellite.

Russia has previously tested releasing objects from satellites in orbit, which one senior U.S. official described in 2017 as a nesting doll, and said it “exhibited characteristics of a weapon system.” In July 2020, Cosmos 2543 released an object that traveled at up to 186 meters per second relative to the satellite. Both the United States and United Kingdom subsequently issued public condemnations of the test, noting that it had the hallmarks of a counterspace weapon. In 2026, the commander of U.S. Space Command said it was “evident” that Russia was deploying a “space weapon” with Cosmos 2558. Although none of these tests occurred near non-Russian satellites, over the last several years, Russia has maneuvered satellites into coplanar orbits with respect to U.S. government and commercial satellites, raising concerns from U.S. officials.

Maneuvering a satellite in LEO into a coplanar orbit is unusual because it requires a large expenditure of fuel—a limited resource on a satellite—and is not part of the standard mission profile for most satellite missions, including broadband and remote sensing. A satellite in an orbit coplanar to another satellite is positioned to quickly move, with little additional fuel expenditure, into place for conducting close-proximity operations. Close-proximity operations could have a benign purpose, such as satellite servicing or debris removal, but might also presage the deployment of a kinetic or non-kinetic counterspace weapon or a hostile grappling operation. The concern arises, then, that a potentially hostile satellite could project kinetic or non-kinetic energy on a target satellite. A Russian satellite conducting plane-matching maneuvers with a Western satellite is, thus, justifiably raising significant alarm. The West needs a unified approach toward deterring this specific type of behavior: Russia maneuvering its satellites into plane-matched orbits, possibly paired with a standoff distance, with non-Russian satellites in LEO. The United States and Europe certainly also want to deter Russian use or testing of on-orbit kinetic weapons near their satellites.

Over the last several years, Russia has deployed increasingly aggressive hybrid warfare against U.S. and European interests. Russia has conducted cyberattacks, interfered with satellite navigation signals, and planned sabotage operations, including against undersea cables, space infrastructure on Earth, and a German airport, using a drone. The frequency of these attacks is also increasing. Using a counterspace weapon against a Western satellite may fit this pattern. Additionally, Russia has said it might consider commercial satellites supporting Ukraine to be legitimate military targets.

The United States and its allies should expeditiously consider several questions. How can the United States and its partners deter Russia from testing or using any type of counterspace capability near a U.S. or friendly satellite? While Russian satellites have conducted such activities near other Russian satellites, no public information indicates they have done so near non-Russian satellites. If Russia does conduct counterspace operations near a U.S.-registered commercial satellite, what should be the U.S. and allied response? Possible responses include canceling the recent diesel deal between the United States and Russia and cracking down on Russian shadow fleet operations. The United States and its partners should also consider the implications of more widespread Russian coplanar activities in LEO near U.S. and allied satellites.

No one should assume to know what Russia will do next with Cosmos 2612, but the potential for a threat is there. Washington and its allies may think that hostile actions targeting a Western satellite would be highly escalatory—but Moscow may be willing to take that risk, believing the West will not respond forcefully. Russia may see little risk of escalation, a belief that is reflected across Russian actions in Europe. The United States and Europe must respond assertively if Russia makes a hostile act against another nation’s satellite. A muted Western response would signal to Moscow that it can continue to expand the envelope of its gray zone actions with little risk of escalation, with reverberations well beyond outer space.
