Since Russia's invasion of Ukraine in 2022, the West has woken up to the unprecedented multi-domain threat to its security that combines potential military aggression, hybrid warfare including sabotage and assassination campaigns, and an increased appetite for confrontation in space. Russia's continued development of anti-satellite weapons, including kinetic interceptors, electronic warfare systems, and potentially nuclear devices targeting Western satellites, represents a deeply concerning escalation. But an equally—perhaps even more—insidious threat could be emerging in space, mirroring its ongoing, less visible sabotage war across Europe: the threat of orbital sabotage operations ranging from targeted satellite interference to the most destabilizing possibility of nuclear detonation in space.
Russia has been engaging in a sabotage war in Europe since its full scale invasion of Ukraine, perfecting its recruiting and operational techniques and its art of (im)plausible deniability. These operations have unfolded alongside information warfare, kinetic attacks on critical infrastructure, and assassination attempts. Russia is already engaging in various forms of non-kinetic interference against Western and US satellites, including signal jamming, laser dazzling of satellites, and the close proximity maneuvering of Russian ‘inspector satellites' near foreign space assets. While those activities exist in the grey zone between routine space operations and hostile action, they demonstrate Russia’s willingness to extend its campaign of interference into the space domain, suggesting that more aggressive actions could follow.
Russia’s approach to sabotage is deeply embedded in its grand strategy, seeking to restore its status as a great world power by exploiting vulnerabilities in a globalized world as instruments of hybrid war. This doctrine, rooted in Cold War practices, treats sabotage not as an auxiliary tool but as a core instrument of statecraft. This extends to space, where Moscow seeks to reassert power and resist perceived Western encroachment.
The contemporary space domain encompasses a complex mix of military, commercial, and civilian satellites providing critical services to both civilian and military users, including GPS navigation, communications, intelligence gathering, and missile warning systems. Modern societies now depend on space-based assets as essential critical infrastructure, from financial transactions and power grid synchronization to emergency services and agricultural operations. This space is governed by international treaties like the Outer Space Treaty of 1967, but enforcement mechanisms remain weak. States typically protect their space assets through diplomatic means, operational security, and increasingly through defensive measures like satellite maneuverability. While kinetic attacks on satellites remain rare, the space domain has already witnessed various forms of conflict, including electronic warfare against satellite communications, cyber attacks on ground stations, and several kinetic ASAT demonstrations that created dangerous debris fields. However, an overt attack on US satellites by a highly visible anti-satellite (ASAT) missile such as Nudol, would likely provoke a similarly visible response. Another impediment to using ASAT missiles to target individual satellites is the current approach taken by the US to switch to satellite constellations, such as the Proliferated Warfighter Space architecture, a mesh network of hundreds of satellites capable of providing the necessary support to modern military campaigns. To address that scale, maintain implausible deniability in space, and avoid creating the massive debris fields that kinetic ASAT weapons generate (debris that threatens all space assets including Russia's own satellites), Russia is more likely to use the same approach it has been practicing so successfully, an approach that has yet to provoke a serious response. Russia has demonstrated this non-kinetic approach through various means, including deploying so-called 'inspector satellites' that can maneuver close to foreign satellites to collect signals intelligence or potentially interfere with their operations while maintaining plausible cover as legitimate space situational awareness activities.
Russia’s nuclear saber-rattling—routinely performed since the invasion of Ukraine—targets Washington, London, Berlin, and other capitals, aiming to deter Western support for Ukraine. This pattern of habituation—repeatedly making an idea once considered outrageous more plausible—suggests that Russia could combine its sabotage tactics with nuclear threats in space, creating a new form of covert interference. The consequences of such sabotage are particularly troubling, as it could cause long-term damage to satellites, disrupting critical military, intelligence, and commercial functions.
Through continued development of space-based capabilities, Russia aims to project military power, maintain deterrence, and challenge U.S. technological and military dominance. Viewing space as essential to military success, it treats offensive space operations as a precursor to broader conflict—using both kinetic and non-kinetic capabilities as strategic deterrents and tools for escalation management. Russia’s escalation logic, based on the belief that conflict can be controlled and that early escalation yields advantage, extends into its space strategy and fuels its actions against U.S. and NATO satellites.
Recognizing early on the West’s reliance on space-based communications, navigation, and intelligence—and unable to replicate these capabilities due to economic constraints, institutionalized corruption, declining space capabilities, and its own strategic culture—Russia has focused on degrading adversary space systems as a cost-effective strategy. Among its developments are co-orbital ASAT technologies and satellite inspection capabilities, allowing it to approach, interfere with, or disable U.S. satellites. These systems are most effective against individual high-value targets, a limitation not lost on Russia.
Russia is already conducting non-kinetic sabotage operations that target the West’s technological infrastructure, including in space. These efforts include cyberattacks on satellite ground stations, electronic warfare to jam or spoof GPS signals, and interference with satellite communications. In Ukraine and along NATO’s eastern flank, GPS jamming has disrupted navigation systems used by both military and civilian aircraft. These tactics are low-cost, hard to attribute, and fit seamlessly into Russia’s broader strategy of hybrid warfare. A nuclear-powered satellite designed to degrade space systems through intensified radiation would not be a departure from this approach—it would be a natural, though far more dangerous, extension.
While the shift toward smaller, cost-effective satellite constellations has reduced the vulnerability of satellites to kinetic attacks, Russia continues to advance nuclear-armed ASAT technology and so-called 'exotic nuclear delivery systems'. This Western shift, however, compels a corresponding evolution in Russia’s sabotage strategy. It is nuclear-powered satellites—capable of maneuvering across orbits and generating energy for anti-satellite operations—that could allow Russia to inflict widespread damage through sabotage. Nuclear-powered satellites, in the event of a real or staged 'malfunction,' along the lines of 2019 'isotope-fuel' engine explosion at the Nyonoksa test site near the inner Van Allen radiation belt, could trigger a phenomenon known as 'nuclear pumping'—a concept explored during the Cold War. This involves using a nuclear explosion to energize surrounding particles and artificially intensify radiation levels in space, effectively turning parts of low-Earth orbit into hazardous zones. Such an event could damage or disable nearby satellites, reduce the operational lifespan of critical systems, and disrupt commercial and military activities—all while allowing Russia to plausibly deny direct involvement.
One recent example is Cosmos 2553, a Russian satellite launched in 2022 and placed in a rarely used graveyard orbit—an area within the Van Allen radiation belt that hosts only a handful of long-dead satellites. Officially, its purpose is to test systems under high-radiation conditions. But its location and timing have raised speculation that it may serve as a test platform for future nuclear-powered or nuclear armed satellites. A long-rumored nuclear-powered satellite designed for electronic warfare, Ekipazh could serve as a model for future orbital sabotage. Were such a satellite to suffer a nuclear engine ‘malfunction,’ thousands of satellites could be immediately damaged or have their lifespan drastically shortened. While Russian space assets would also be affected, the impact on its military operations would likely be limited—a calculated tradeoff favoring disruption over preservation.
Russia sees itself at war with the West, its chief adversaries the U.S. and NATO. In modern conflict, where information dominance is decisive, the systems that support it—essential in both wartime and peacetime—become primary targets. The U.S.'s reliance on space assets exemplifies this vulnerability. Recent diplomatic pressure on Ukraine to consider negotiations with Russia highlighted another critical reality: modern war is inseparable from satellite-based intelligence and targeting. Much of Ukraine’s battlefield effectiveness—from precision strikes on Russian logistics to early warning of missile attacks—relies on access to Western intelligence, surveillance, and reconnaissance (ISR) and geospatial data. Without these space-based systems, real-time targeting, coordination, and threat detection would be severely compromised. This dependence was starkly demonstrated in early 2025 when the Trump administration temporarily suspended intelligence sharing with Ukraine, including cutting off access to U.S. government-purchased commercial satellite imagery such as Maxar data. The pause left Ukrainian forces without critical space-based intelligence support, with Western partners who had helped process satellite intelligence departing from military headquarters in Kyiv. This episode underscores how dependent even conventional wars have become on the constant, uninterrupted availability of orbital assets—and how damaging their disruption could be.
Russia’s investment in ASAT weapons, while serious, will not transform its strategic position unless integrated into a broader military doctrine. Like other advanced systems, their impact depends not on quantity but on strategic use—challenging simplistic assumptions about technology determining outcomes. Even if Russian ASATs degrade U.S. capabilities, this alone will not decide a conflict. But their potential consequences warrant serious concern. Their integration into Russia’s military thinking demands close and sustained attention from the West. In the event of nuclear sabotage in space, the consequences could ripple across multiple sectors. Systems that rely on satellites—including communications, navigation, weather monitoring, and financial infrastructure—could face degraded performance, higher operational costs, and long-term disruptions. With limited global launch capacity, replacing damaged or disabled satellites would take time, compounding the impact and raising the stakes.
Russia’s embrace of sabotage—rooted in Cold War doctrine—holds nothing sacred. It zooms in on the most critical dependencies, exploiting vulnerabilities in a globalized world. Its space strategy is no exception. Russia’s approach to space is not an outlier—it’s an extension of the same doctrine driving its actions in Ukraine, Europe, and beyond. The tools may differ—covert satellite interference, radiation fields, nuclear-powered sabotage—but the logic is familiar: disrupt, deny, and escalate under the cover of ambiguity. The threat is not just technical, but strategic: recognizing that space is already contested, and that the line between peace and war has long since blurred.
