Russian Military Satellite Flies Within Kilometer of American Satellite Supporting Ukrainian Military
In an unprecedented move, a Russian military satellite in Low Earth Orbit maneuvered dangerously close to ICEYE-X36, an American-registered radar imaging satellite with ties to the Ukrainian war effort. This maneuver, conducted on October 17, may have brought the Russian military satellite Kosmos 2612 as close as a few hundred meters from ICEYE-X36 without the express consent of ICEYE’s operators, posing a significant danger to both craft, as well as other nearby satellites. This is the first known instance of a satellite conducting a close rendezvous with a non-consenting target, and likely represents a serious violation of international law.
Kosmos’ close approach, first noticed by satellite trackers several days prior, sparked fears that the Russian satellite might deploy an anti-satellite (ASAT) weapon to disrupt, disable, or even destroy ICEYE-X36. The incident comes in the wake of western intelligence assessments indicating that Moscow is working to develop its own ASAT capabilities as a counter to western dominance in space. It remains unknown whether Kosmos 2612 did, in fact, undertake any hostile action against ICEYE-X36 during their close encounter, as the current status or functionality of the latter remains unclear. Kosmos 2612 has since distanced itself from ICEYE-X36.
Absent any reports of a malfunction with ICEYE-X36, this incident likely represents an effort by Russia to demonstrate its ability to deliver a co-orbital ASAT payload against a western target. This may also be intended to intimidate satellite communications and imagery providers considering supporting Ukraine.
The American Satellite: ICEYE-X36
ICEYE-X36 is an American-registered radar imaging satellite owned by the Finnish firm ICEYE. Publicly-available information indicates that ICEYE-X36 has a total mass of only around 90 kg (200 lb), and a hard-body radius (essentially, the maximum size of the satellite in any one dimension) of around 1.6 m (5.25 ft). Launched on March 4, 2024 on SpaceX’s Transporter-10 rideshare mission, ICEYE-X36 is one of more than 70 satellites in ICEYE’s constellation of synthetic aperture radar imaging satellites. Synthetic aperture radar, or SAR, is a form of high-resolution, all-weather, 24-hour radar imaging used for a wide variety of purposes, including military reconnaissance. ICEYE advertises its satellite constellation as being capable of SAR imaging at resolutions as high as 25 cm (10 inches) per pixel.
ICEYE makes no secret of the fact that its satellites are used by various customers, including Ukraine, for intelligence and military planning purposes. In fact, the company’s website explicitly promotes the constellation’s utility for military commanders and decisionmakers. One of these customers is, indeed, the Ukrainian Ministry of Defense, with whom ICEYE announced an expanded partnership in January 2026. However, ICEYE (along with its American-flagged satellites) legally remain neutral, and thus cannot lawfully be targeted by Russian forces.
The Russian Satellite: Kosmos 2612
While a great deal is known about ICEYE’s constellation, Kosmos 2612’s design and purpose, on the other hand, are almost completely unknown. It was launched from Russia’s Plesetsk Cosmodrome on a Soyuz-2.1b rocket on April 16, 2026, presumably as part of the rocket’s classified payload. The launch attracted attention for its use of the rare, restartable Volga upper stage, a stage associated with high-precision orbital plane changes and maneuvers. Indeed, such maneuvers were subsequently observed by the U.S. Space Force via ground-based radar, which cataloged no fewer than 8 assessed payloads, released into two different orbital planes. Kosmos 2612, designated at the time as “Object H,” was one of five payloads released into its orbital plane. The other payloads, designated Kosmos 2610 through 2614, have not made any similarly close approaches, but remain roughly aligned with ICEYE-X36’s orbital plane.
On September 29, Kosmos 2612 significantly increased its own altitude in order to set up its approach of ICEYE-X36. This altitude change was largely reversed in a second thruster firing on October 11, followed shortly after by a series of adjustments made over the course of October 13 to 15 that fully aligned the two satellites’ orbits.
The Broader Picture: Russia’s Satellite War
Russia is increasingly incensed by western satellite providers’ willingness to aid Ukraine in defending itself, a state of affairs that has heightened concerns Russia might attempt to use an ASAT weapon against one of ICEYE’s satellites. Since the early days of the war, western satellite constellations have functioned as potent force multipliers for the Ukrainian military, providing real-time intelligence and communications for frontline units. Starshield, the military version of SpaceX’s Starlink, is frequently used by Ukraine for mid-course guidance of long-range drones, as well as the remote operation of explosive naval drones. Both Starlink and Starshield are also frequently used by Ukraine for battlefield command and control. Orbital imaging constellations, such as ICEYE’s satellites, have also been used by Ukraine for reconnaissance and intelligence.
This situation has increasingly angered the Kremlin, which views such assistance as direct, Western participation in the war. Russia has repeatedly stated its willingness to potentially disable or destroy satellites such as ICEYE’s, referring to them as “quasi-civilian” and deliberately jamming satellite location systems, including GPS, that it considers to be aiding the Ukrainian military. In spite of international law clearly stating otherwise, Russian leadership considers any effort by western satellite providers to help Ukraine to be wholly unacceptable.
This incident thus marks a significant escalation in Russia’s multifaceted pressure campaign against space-based support of Ukraine. Previously, Russia has limited its actions to verbal threats and jamming. The aim of Kosmos 26 12’s intrusion, however, seems to be far more direct: to demonstrate that Russia has deployable, on-orbit ASAT capabilities capable of targeting western space infrastructure, and possibly to gather signals intelligence from ICEYE-X36. Kosmos 2612’s flyby can also be viewed as part of Russia’s broader campaign of increasingly violent sabotage against NATO countries, including attempted attacks on transportation infrastructure and routine violations of NATO airspace.
Legal Ramifications
Kosmos 2612’s maneuvers represent a flagrant violation of international law by the Russian military. Under Article IX of the 1967 Outer Space Treaty (OST), states engaged in space activities are required to take due consideration of the rights of others to peacefully use outer space:
“In the exploration and use of outer space…States Parties to the Treaty…shall conduct all their activities in outer space, including the Moon and other celestial bodies, with due regard to the corresponding interests of all other States Parties to the Treaty.”
Article IX’s “due regard” requirement functions as something between a duty of care and a duty to respect the interests of others. Acting in accordance with due regard means avoiding action that might effectively infringe on other states’ right to peacefully use and explore outer space, whether that infringement might come from malicious action or mere carelessness. Kosmos 2612’s close approach of ICEYE-X36 would appear to clearly violate this principle, as even the smallest error on Kosmos’ part could have led to a destructive collision.
In the event that Kosmos 2612 had damaged ICEYE-X36, the Russian Ministry of Defense would likely be held responsible under international law. Article III of the 1972 Liability Convention establishes that if damage occurs to an object in space, a state is only liable for the damage that occurred due to its own negligence, recklessness, or intentional behavior. (This is as opposed to damage caused on the ground or in the air, which operates on a strict-liability regime: even if a state acted in a perfectly reasonable manner, it remains fully liable.) Absent evidence that Kosmos 2612 had been forced into a close rendezvous with ICEYE-X36 by some outside force, the burden of liability would fall squarely upon Kosmos’ Russian operators.
International Reactions
The first public reaction by the U.S. government came on October 21, at a meeting of the U.N. General Assembly’s First Committee on the weaponization of space. U.S. delegate Thomas Hardesty slammed Kosmos 2612’s maneuvers, stating:
Just last weekend, Russia’s Ministry of Defense satellite Kosmos 2612 exhibited threatening behavior by intentionally maneuvering dangerously close to a commercial satellite. These behaviors appear consistent with an on orbit weapons operation.
The decision to conduct these activities was deliberately reckless and violated long established safety thresholds in low earth orbit. The United States believes these maneuvers are being conducted in an unprofessional manner and do not reflect the behavior of a responsible spacefaring nation.”
U.S. Delegate Thomas Hardesty
The Russian government used the platform of the First Committee meeting to dismiss western concerns as alarmist while asserting that Kosmos 2612’s actions were entirely peaceful in nature. Russian representative Konstantin Vorontsov, who had previously referred to western satellite constellations assisting Ukraine as “legitimate targets,” instead attempted to place the focus on the United States, arguing that U.S. military programs such as the conceptual “Golden Dome” anti-ballistic missile system demonstrate “the aggressive thrust of the U.S. space activity.” Vorontsov also criticized the U.S.’ continued refusal to sign a treaty formally banning the placement of weapons in outer space. (The U.S., along with most western countries, considers such a treaty to be a bad-faith effort by Russia and China to limit other states’ anti-satellite capabilities while retaining their own.)
ICEYE, for its part, has not backed down from its support for Ukraine and its military. On October 22, ICEYE and Finnish telecom firm Nokia announced a partnership with the Ukrainian Ministry of Defense to explore sovereign satellite communication systems as an alternative to SpaceX’s Starshield, which recently had its capabilities in Ukraine limited at the instructions of Elon Musk. It is unclear how this initiative will interface with UASAT, Ukraine’s existing initiative for sovereign satcom capabilities.
