In a chilling reminder of the ongoing electronic warfare in Europe’s skies, a plane carrying European Commission President Ursula von der Leyen was hit by suspected GPS jamming while approaching Plovdiv Airport in Bulgaria.1 The incident, which occurred on Sunday, August 31, 2025, forced the pilots to rely on traditional, analog navigation methods, a stark reversion to pre-digital aviation.2 While the aircraft landed safely, the event has sent shockwaves through Brussels, with EU officials treating it as “undeniable interference” and pointing the finger directly at Russia.3 This is not an isolated incident but the latest and most high-profile example of a growing pattern of Russian-linked electronic interference that European governments fear could lead to a major aviation catastrophe.
The incident unfolded as von der Leyen was flying from Warsaw to Plovdiv as part of a four-day tour of “frontline” EU states bordering Russia.4 As the plane began its descent, the pilots lost all satellite navigation signals in the area, a phenomenon known as GPS jamming.5 For nearly an hour, the crew was forced to circle the airport, unable to trust their primary navigation systems.6 In a testament to their training, the pilots ultimately relied on ground-based navigation and paper maps to land the aircraft safely.7 An official familiar with the incident described the situation to The Financial Times, noting, “The whole airport area GPS went dark.”8 This type of interference, which overwhelms satellite signals with radio noise, has become a regular occurrence in the Baltic Sea and Eastern Europe, affecting not only aircraft but also ships and civilian navigation systems.9
The alleged motive behind the interference is complex. EU officials believe the incident is part of Russia’s “hybrid warfare” strategy, a combination of conventional and unconventional tactics designed to destabilize and intimidate its neighbors.10 The interference is seen as a message to Europe, a display of Russia’s ability to disrupt critical infrastructure and undermine the continent’s security.11 It is particularly pointed, given von der Leyen’s strong pro-Ukrainian stance and her tour of countries that are key military suppliers to Kyiv.12 During her visit to Bulgaria, a major producer of military equipment, she stated, “Russian president Vladimir Putin has not changed, and he will not change. He is a predator. He can only be kept in check through strong deterrence.” Her words, delivered just after the GPS incident, underscore the high-stakes geopolitical game being played in the air.
While Russia has not officially commented on this specific incident, the Kremlin has a history of denying similar accusations.13 However, a growing body of evidence, including reports from air traffic control authorities in the Baltic states, points to a clear pattern of Russian electronic warfare. The Russian exclave of Kaliningrad and areas along its western frontier are known hot spots for these activities, which include both jamming and “spoofing,” a more dangerous tactic where false GPS signals are transmitted to deceive receivers. European officials have warned that these actions are not just a nuisance but a serious threat to aviation safety.14 The incident with von der Leyen’s plane now serves as a powerful new catalyst for the EU to accelerate investments in its own defense capabilities, including its independent satellite navigation system, Galileo, to reduce its reliance on the U.S.-owned GPS network.15

Separate Answer: When, Where, Why, and Who
When
The GPS jamming incident occurred on Sunday, August 31, 2025.31
Where
The plane was over Bulgaria, approaching Plovdiv International Airport.32
Why
EU officials and aviation experts suspect the GPS jamming was an act of Russian “hybrid warfare.”33 The interference is believed to be a calculated signal to the European Union, demonstrating Russia’s ability to disrupt critical civilian infrastructure and undermine security, particularly during a tour by a high-profile figure who is a strong supporter of Ukraine.34
Who
- The Target: The plane carrying Ursula von der Leyen, the President of the European Commission.35
- The Suspect: Russia is suspected by EU officials and authorities in Bulgaria of being behind the interference.36
- The Affected: The pilots and other passengers on the aircraft, as well as the Bulgarian air traffic control system.37
