Russia's Satellite 'Stalking' of Ukraine-Linked Space Assets Raises Global Security Concerns

A Russian military satellite, Cosmos 2612, has reportedly maneuvered to within meters of a US-registered radar satellite, ICEYE-X36, which is believed to provide intelligence to Ukraine. This close proximity was tracked by space-monitoring data and reported by The War Zone, a US defense news outlet. LeoLabs, a US space-tracking firm, indicated the closest approach was approximately 500 meters, according to Breaking Defence. ICEYE has been supplying radar imagery to Ukraine since 2022, as reported by Defence News.

The incident involves Cosmos 2612, one of six satellites launched by the Russian military in April. In May, four of these satellites reportedly moved near an ICEYE satellite. ICEYE-X36 is a commercial satellite owned by the US arm of the Finnish company ICEYE, which sells radar imagery to military entities and provides data to the US and its allies. ICEYE's CEO, Rafal Modrzewski, stated that the company moved its satellite, which appeared to prompt further Russian maneuvers.

Between Thursday and Friday of the previous week, Cosmos 2612 closed the distance from over 320 km (200 miles) to about 4.8 km (3 miles) from ICEYE-X36, according to LeoLabs' report to Axios. Over the weekend, the Russian satellite positioned itself ahead of and behind the ICEYE satellite, at times coming within roughly 500 meters. LeoLabs noted that this estimate had uncertainty and that by Monday, Cosmos 2612 had begun to move away.

A Ukrainian official confirmed to Axios that Ukraine's military collaborates with ICEYE and utilizes its capabilities, though it remains unclear if ICEYE-X36 specifically supports Ukraine.

Historically, Russia has primarily conducted such maneuvers against Western military satellites, not commercially owned ones, according to Mark Hilborne, a senior lecturer at King's College London. In early 2020, two Russian satellites approached USA 245, a US spy satellite. In September 2025, German Defence Minister Boris Pistorius stated that two Russian Luch-Olymp satellites were tracking two Intelsat satellites used by the German military.

While close approaches between satellites have occurred for years, this incident is notable. Hilborne described it as the first time a country has performed such a maneuver against a commercial satellite without consent, and at an "incredibly close" distance, with some reports suggesting less than 30 meters. More common interference methods include jamming satellite signals, often from the ground. Western military officials have reported a significant increase in Russian interference with Western space systems since the full-scale invasion of Ukraine in 2022.

The significance of this event lies in Russia's apparent disregard for the distinction between commercial and military satellites as potential targets, according to Hilborne. This is critical as militaries, including Ukraine's, increasingly depend on commercial satellites for communication and imagery. Russia has previously warned that "quasi-civilian infrastructure may be a legitimate target for a retaliatory strike," as stated by a senior Russian foreign ministry official at the UN in October 2022.

Juliana Suess, a space security researcher, suggests Russia might be calculating that shadowing a commercial satellite, especially one not belonging to the US, would elicit less severe reactions than targeting a sovereign one. However, the ownership of ICEYE-X36 is complex, as it is owned by ICEYE's US subsidiary and registered as a US satellite, creating a "complex problem," according to Hilborne. The proximity, even within 5 km, is considered "essentially a hop and a skip in space" and could potentially enable Russia to intercept data or disrupt services, possibly through signal jamming. A kinetic attack is also possible but deemed less likely due to its unprecedented nature against a satellite.

Analysts believe Russia is likely sending a message and escalating simultaneously. Hilborne suggests it signals that these platforms are under threat and represents an escalation, indicating Russia's potential willingness to attack, as any satellite could be weaponized by crashing into another. Suess emphasizes that the political goal of intimidation should not be underestimated, and the maneuver serves as a reminder that space assets are not immune to the conflict in Ukraine. This echoes Russia's 2021 destruction of one of its own satellites with a missile, an event referenced in the EU's 2023 space strategy.

Moscow refers to such spacecraft as "inspector satellites" and has described such maneuvers as common practice by "many countries." Hilborne characterizes the approach as "activity that sits below the threshold of conflict." An outright attack on ICEYE-X36 appears unlikely for now, given the current conflict dynamics and the satellite's US registration, which could lead to unpredictable responses. The creation of space debris from an attack would also pose a universal problem. However, Hilborne cautions that it is "hard to second-guess where Russia draws the line."

Ukraine's access to space-based assets has faced pressure before, including from allies. In March 2025, the US National Geospatial-Intelligence Agency temporarily suspended Ukraine's access to US government-purchased commercial imagery when Washington paused intelligence sharing with Kyiv. While disruption of ICEYE-X36 would not render Ukraine blind due to the ICEYE constellation and potential data from sovereign satellites like Germany's, the speed of data transfer is crucial. Enhanced access agreements this year have improved data speed, but enabling similarly fast transfers with a new provider remains a question.

Adding to these pressures, a recent order from the White House limited the use of Starshield, the military-grade version of SpaceX's Starlink service, for Ukraine. US Secretary of State Marco Rubio confirmed on Saturday that Starshield is currently unavailable to Ukraine, though Kyiv's request to use it for attacks deep inside Russia is reportedly under discussion.
