Russian Satellite Nears Western Radar Satellite: A Warning Signal From Space

According to space-tracking data published by the US defense outlet The War Zone, a Russian military satellite designated Cosmos 2612 maneuvered to within a few hundred meters of a US-registered radar satellite believed to be providing intelligence to Ukraine.

The satellite that Cosmos 2612 approached is ICEYE-X36, owned by the US subsidiary of Finnish company ICEYE. Space-tracking firm LeoLabs estimated the closest approach between the two objects at roughly 500 meters. According to Defence News, ICEYE has supplied radar imagery to Ukraine since 2022.

What happened

According to The War Zone, Cosmos 2612 is one of six satellites the Russian military launched in April. By May, four of them had moved close to an ICEYE satellite. ICEYE-X36 is a commercial satellite owned by a private company, but ICEYE sells radar imagery to military forces and provides data to the United States and its allies.

ICEYE chief executive Rafal Modrzewski told Reuters that the company subsequently moved its satellite, a step that appeared to prompt further maneuvering by the Russian side.

According to LeoLabs, between last Thursday and Friday, Cosmos 2612 closed the distance to ICEYE-X36 from more than 320 km to about 4.8 km. Over the weekend, the satellite moved back and forth between positions ahead of and behind the ICEYE craft, at one point closing to about 500 meters. LeoLabs noted that the estimate carries some uncertainty and that by Monday the Russian satellite had begun moving away.

A Ukrainian official told Axios that Ukraine's military works with ICEYE and uses the company's capabilities, but said it was unclear whether ICEYE-X36 itself was supporting Ukraine.

Precedent and prevalence

Mark Hilborne, a senior lecturer in defense studies at King's College London, told Al Jazeera that Russia had previously carried out similar maneuvers mainly against Western military satellites, not privately owned ones.

In early 2020, two Russian satellites moved close to USA 245, a US reconnaissance satellite. In September 2025, German Defense Minister Boris Pistorius said two Russian Luch-Olymp satellites were tracking two Intelsat satellites used by the German military.

According to Hilborne, close approaches have occurred for years, but never quite like this. He described it as "the first time a state has done this to a commercial satellite without any consent," adding that the distance was "extremely close," with some reports citing figures below 30 meters.

Far more common are interference operations that do not require approaching a satellite, mainly signal jamming, usually carried out from the ground. Western military officials told Reuters that Russian jamming of Western space systems has increased significantly since Moscow launched its full-scale military campaign in Ukraine in 2022.

What it means

For Hilborne, the choice of target "begins to show that Russia does not distinguish between commercial and military satellites when treating them as potential targets." That matters because military forces, including Ukraine's, are increasingly reliant on commercial satellites for communications and imagery.

Moscow has issued warnings on the issue before. In October 2022, a senior Russian Foreign Ministry official told the United Nations that "quasi-civilian infrastructure could be a legitimate target for a retaliatory strike."

Juliana Suess, a space security researcher at the German Institute for International and Security Affairs (SWP) in Berlin, suggested Russia may be calculating that the reaction would be less severe if it shadowed a commercial satellite rather than one under national sovereignty, especially a non-US one.

Ownership, however, is not that simple. Hilborne noted that ICEYE-X36 is owned by ICEYE's US subsidiary and registered as a US satellite, which "creates a complicating issue."

Distance is also a key factor. Suess argued that under 5 km may sound far, but "it is basically a hop in space." She added: "It is extremely close and could allow Russia to carry out dangerous operations, including intercepting data from the satellite or disrupting its service, for example temporarily through signal jamming. A kinetic attack is also possible but seems less likely at this point, partly because it would be an unprecedented step against a satellite."

Message or escalation?

Analysts say the move could carry both meanings. Hilborne said: "This is a message that these platforms can be put under threat," adding that the incident also represents escalation, showing Russia may be willing to strike, since any satellite can be used as a weapon simply by crashing into another.

Suess added: "I think whether or not we see further maneuvers or consequences, the political aim of the threatening behavior should not be underestimated." In her view, the move is also a message that space assets cannot be considered entirely safe or outside the war in Ukraine.

She cited the November 2021 event in which Russia used a missile to destroy one of its own satellites, an incident referenced in the European Union's 2023 space strategy. "We have long known what Russia is capable of in terms of disrupting or even destroying space assets. This move is also a reminder of those previously demonstrated capabilities," she said.

Moscow calls such spacecraft "inspector satellites" and in 2020 described similar maneuvers as common practice "of many countries," according to Radio Free Europe/Radio Liberty. Hilborne described the move as "another example of activity below the threshold of conflict."

According to Hilborne, a direct attack on ICEYE-X36 is not currently likely. "Given the current balance in the conflict, and this being a US-registered satellite, it seems unlikely Russia would actually attack it, because the response would be unpredictable," he said. An attack could also create a large amount of space debris, causing problems for all sides, he warned, adding that "it is very hard to gauge where Russia draws the line."

How does Ukraine keep its eyes in space?

Ukraine's access to satellites has come under pressure before, at times from its own allies. In March 2025, when Washington paused intelligence sharing with Kyiv, the US National Geospatial-Intelligence Agency "temporarily suspended" Ukraine's access to the main portal for commercial imagery purchased by the US government.

According to Suess, if ICEYE-X36 were disrupted, Ukraine would not necessarily be "blind," because the ICEYE constellation has more than one satellite, and nationally owned radar satellites such as Germany's could also provide data. The problem, however, is speed. She explained that, according to ICEYE, expanded access agreed this year means faster access to data.

She asked: "The question is whether similarly fast data delivery can be guaranteed with a new provider, whether commercial or nationally owned."

Ukraine now faces another pressure. Last week, restrictions on Starshield, the military-grade version of SpaceX's Starlink service, for Ukraine were imposed from within the White House, according to two US officials and a Western official who spoke to Reuters. On Saturday, US Secretary of State Marco Rubio said Starshield is currently not available to Ukraine, but Kyiv's request to use the service for deep strikes into Russian territory is "under discussion."
