The Baltic region is becoming a testing ground for a new kind of hybrid warfare—one of the most dangerous zones of electronic confrontation between Russia and NATO, where strikes are delivered not with missiles but with radio signals. What just a few years ago was considered isolated technical failures has now taken on the characteristics of a systematic campaign of Russian electronic interference, disrupting civil aviation, satellite navigation, and even aircraft carrying senior NATO officials.
According to European aviation authorities and analysts, tens of thousands of GPS interference incidents were recorded in the Baltic Sea region between 2024 and 2026. The highest concentration was observed over Estonia, Finland, Latvia, Lithuania, Poland, and the Baltic Sea itself. European and British experts primarily link the source of the interference to Russia’s Kaliningrad region and military facilities in the country’s northwest.
From a technical standpoint, Russia employs two main electronic warfare tools: GPS jamming—the suppression of satellite navigation signals—and GPS spoofing—the manipulation of positioning data. In both cases, the functioning of navigation systems used by aircraft, ships, drones, and digital infrastructure is disrupted.
According to analysts at the Royal United Services Institute, the intensification of Russian interference is directly linked to the war against Ukraine. Following Ukrainian long-range drone strikes on Russian territory, Moscow significantly expanded the use of electronic warfare systems around strategically important regions, particularly Kaliningrad and the Leningrad Military District. At the same time, Russian systems create vast zones of navigational uncertainty extending far beyond Russian territory, with increasing impact on European civil aviation.
The first major warning sign came in spring 2024 with an incident involving Finnair. On April 25 and 26, two passenger flights from Helsinki to Tartu, Estonia, were forced to return due to the inability to land safely. The cause was powerful GPS interference near Tartu Airport. By April 29, Finnair had suspended flights on the route until the end of May 2024. This case was unprecedented, marking the first time in the world that regular commercial air service was halted due to electronic warfare interference. Today, according to aviation monitoring platforms, more than 46,000 flights in the Baltic region have encountered similar disruptions, including over 2,300 Ryanair flights and more than 1,300 Wizz Air flights. Estonia was among the first to openly accuse Russia of posing a threat to civil aviation. Estonian Defence Forces Commander Martin Herem stated that Moscow is either testing its electronic warfare capabilities or deliberately exerting pressure on the region and NATO.
In January 2024, members of the European Parliament called on the European Commission to investigate large-scale GPS interference in the Baltic region and to establish a pan-European system for monitoring the electromagnetic environment. Later, the International Civil Aviation Organization (ICAO) officially recognized Russia as a source of systematic interference with Europe’s satellite navigation. Particular attention has been drawn to incidents involving NATO officials as targets. In March 2024, the aircraft of then UK Defence Secretary Grant Shapps experienced GPS jamming near Kaliningrad while returning from Poland, with navigation disrupted for about 30 minutes. At the time, British authorities did not escalate the situation, but two years later a more striking episode occurred. On May 24, 2026, a large-scale electronic attack targeted an RAF Dassault Falcon 900LX carrying UK Defence Secretary John Healey. The incident took place after his visit to Tallinn, where he met with Estonian Defence Minister Hanno Pevkur and British NATO units. During the return flight, the aircraft was without GPS navigation for approximately three hours. Internet access, smartphones, and laptops onboard ceased functioning, forcing the crew to rely on backup inertial navigation systems. British sources described the incident as “reckless Russian interference.” Concerns were heightened by the fact that the aircraft’s route was publicly available on flight tracking services, raising suspicions that the interference may have been a deliberate political signal.
The Healey incident occurred amid increasing Russian activity against NATO aviation. Days earlier, the UK Ministry of Defence reported two dangerous encounters between Russian fighter jets and an RAF Rivet Joint reconnaissance aircraft over the Black Sea. In one case, a Russian Su-35 approached so closely that the British aircraft’s autopilot disengaged and emergency systems were triggered. In another, a Su-27 passed within approximately six meters of the aircraft’s nose. The Baltic Sea is effectively becoming a постоянная зона радиоэлектронного конфликта. On May 19, 2026, another serious incident occurred when a Romanian NATO F-16 shot down a Ukrainian drone over Estonia after it was reportedly diverted by Russian electronic warfare systems. The incident led to a suspension of railway traffic in Latvia and temporary disruptions to security infrastructure.
European governments are increasingly viewing Russian electronic warfare as an element of hybrid warfare. It is no longer just a military tool but a political instrument of pressure, allowing Russia to demonstrate control over parts of Baltic airspace, test NATO’s response, create risks for civil aviation, provoke transport disruptions, and probe the resilience of European infrastructure. The consequences for Europe are significant. EU and NATO countries are being forced to urgently modernize navigation systems, restore backup ground-based guidance, invest in resilience against GPS interference, and revise aviation safety protocols.
The main risk, however, lies elsewhere. Electronic warfare increases the likelihood of accidental catastrophe or military escalation. Pilot error, loss of navigation, false positioning data, or system failures could lead to mid-air collisions, strikes on civilian aircraft, or direct military incidents between Russia and NATO.
Russia, for its part, officially denies responsibility for most incidents. The Kremlin typically avoids comment or attributes events to “military activity” while accusing the West of fueling anti-Russian hysteria. However, the facts indicate that the Baltic region has already become a zone of постоянного электронного воздействия со стороны России. If hybrid warfare was once associated primarily with propaganda, cyberattacks, and sabotage, a new front has now emerged—the struggle for control over navigation, communication, and the digital backbone of modern Europe.
