Von der Leyen Plane GPS Jammed
August 2025 — EC President's Aircraft Diverted
On August 31, 2025, the aircraft carrying European Commission President Ursula von der Leyen was GPS-jammed during approach to Plovdiv, Bulgaria. The crew was forced to switch to ILS approach. Bulgarian authorities investigated and suspected Russian origin. NATO Secretary-General Mark Rutte publicly warned that GPS interference with civil aviation constitutes a serious security threat. This was the highest-profile individual GPS jamming incident in aviation history — and it wasn't the first time a senior official's aircraft was targeted.
What Happened
On August 31, 2025, an aircraft carrying European Commission President Ursula von der Leyen experienced deliberate GPS jamming on approach to Plovdiv International Airport (LBPD) in Bulgaria. The crew, unable to rely on GNSS positioning, was forced to revert to a conventional Instrument Landing System (ILS) approach — the precise contingency procedure GPS interference is designed to defeat by disrupting pilot workload and situational awareness during a critical flight phase. Bulgarian authorities formally attributed the interference to Russian-origin electronic warfare assets operating within range of Bulgarian airspace. NATO Secretary-General Mark Rutte issued a public statement condemning the incident, marking one of the few times a sitting NATO chief has publicly named GPS interference against a civilian VIP flight as a strategic threat.
Bulgaria sits at the southeastern edge of NATO territory, bordering the Black Sea. Russian electronic warfare infrastructure — including systems deployed across occupied Crimea and mainland Russian territory near Rostov-on-Don — has demonstrated effective reach across the Black Sea basin and into the airspace of Romania, Bulgaria, and Greece. The Plovdiv incident was not an isolated anomaly. It was the highest-profile confirmed GPS jamming event ever recorded against a civil aircraft carrying a sitting head of a major international institution, and it immediately prompted EU-level discussions on mandating electronic warfare countermeasures for civil aviation.

Warning Signs
The Plovdiv GPS jamming event did not emerge from a clear sky. The airspace threat environment over southeastern Europe had been systematically deteriorating throughout 2023–2025. Multiple publicly trackable indicators — pilot NOTAM reports, ADS-B anomaly clusters, geopolitical escalation patterns, and the Baltic precedent — collectively painted a picture that a high-profile jamming event in this corridor was a matter of when, not if. Each of the signals below was observable and quantifiable before August 31, 2025.
Russian electronic warfare systems deployed in Crimea (occupied since 2014) and southern mainland Russia have documented coverage reaching 400–600 km across the Black Sea basin. Plovdiv sits approximately 300 km from the Bulgarian Black Sea coast, placing it within effective jamming range of Crimea-based EW infrastructure. This coverage geometry was a known, stable threat factor requiring no new intelligence to assess.
Seventeen months before the Plovdiv incident, UK Defence Secretary Grant Shapps' RAF aircraft was GPS-spoofed over the Baltic region. The event was confirmed and publicised. This was a direct, unambiguous signal that Russian EW operators were willing to specifically target NATO-affiliated senior officials' aircraft — not just general civil aviation. This precedent materially elevated risk for all VIP flights in Russian EW proximity zones.
A sustained multi-year GPS interference campaign originating from the Middle East and expanding into Eastern European airspace corridors produced thousands of logged pilot reports and ADS-B position anomalies between 2023 and 2025. EUROCONTROL GNSS interference reporting tools recorded hundreds of affected flight segments per month across the Black Sea, Eastern Mediterranean, and Baltic regions — a sustained, trackable background signal.
By summer 2025, the geopolitical context — ongoing war in Ukraine, EU sanctions escalation, and von der Leyen personally as a prominent face of EU support for Ukraine — elevated the symbolic value of targeting her aircraft specifically. Threat actors conducting EW operations are not purely opportunistic; pattern analysis of prior targeting decisions shows a preference for high-visibility, high-symbolic-impact events.
GNSS-related NOTAMs and pilot interference reports within the Sofia (LBSR) and Plovdiv (LBPD) terminal areas had been accumulating at elevated frequency in the months preceding the incident. While individually insufficient to predict the August 31 event, the trend line of increasing interference report density in Bulgarian airspace was a quantifiable, observable leading indicator.
Timeline
UK Defence Secretary Grant Shapps' RAF aircraft is GPS-spoofed over the Baltic region while operating near the Kaliningrad exclusion zone. The incident is confirmed and publicised by UK officials — establishing documented proof that Russian EW operators are prepared to selectively target senior NATO officials' aircraft. EUCONTROL issues updated guidance noting elevated spoofing risk in Baltic and Black Sea corridors.
EUROCONTROL's GNSS interference monitoring records an escalating volume of pilot reports across the Black Sea FIR, Bulgarian airspace (LBBB), Romanian airspace (LRBB), and Eastern Mediterranean. Finnair and multiple other Nordic carriers log GPS anomalies near Tartu and Tallinn. The Baltic GPS jamming escalation of 2024 receives formal acknowledgment from NATO military authorities. Russian EW activity in Ukraine conflict zone noted as likely source for southeastern European corridor interference.
GNSS interference reports within Bulgarian terminal airspace increase in frequency. Plovdiv International Airport (LBPD), located approximately 150 km from the Turkish border and within range of Black Sea EW coverage, accumulates approach-phase anomaly reports. No specific public NOTAM for the August 31 arrival, but the background interference density in LBBB FIR has been trending upward throughout the year.
Aircraft carrying European Commission President Ursula von der Leyen begins approach to Plovdiv International Airport (LBPD). GPS signal is actively jammed. The flight crew detects GNSS unreliability and initiates a reversion to ILS (Instrument Landing System) approach procedures — the backup navigation methodology designed for exactly this contingency. The diversion of navigation method adds crew workload during the most critical phase of flight. The aircraft lands safely.
Bulgarian aviation and security authorities open investigation. Preliminary findings attribute the interference to Russian-origin electronic warfare assets operating from Crimea or mainland Russian territory near the Black Sea. NATO Secretary-General Mark Rutte issues a public warning — the highest-level NATO statement to date specifically addressing GPS interference against a civil aircraft carrying a senior Western official. PBS, CNN, Euronews, and Defense News provide international coverage, making this the most-publicised GNSS jamming event in civil aviation history.
The European Union convenes formal discussions on mandating electronic warfare countermeasures for civil aviation — including requirements for GNSS-independent backup navigation capabilities and enhanced onboard interference detection systems. EASA begins scoping a regulatory review of GNSS dependency standards for commercial and government aircraft operating in contested electromagnetic environments. NATO working groups accelerate work on civil-military coordination frameworks for EW threat notification.
Aviation Impact
The operational and strategic impact of the Plovdiv incident extends well beyond the single flight. It represents a crystallisation point for years of accumulating GNSS interference risk across European airspace — and the moment at which the threat could no longer be treated as a background nuisance rather than an active, targeted security posture by a state actor.
No prior confirmed GPS jamming incident against a civil or government aircraft has involved a target of equivalent institutional seniority — the sitting President of the European Commission, representing 27 member states and 450 million citizens.
Within 17 months, two separate confirmed GPS interference events targeted aircraft carrying senior NATO/EU officials: UK Defence Secretary Shapps (March 2024, Baltic) and EC President von der Leyen (August 2025, Bulgaria). A pattern of deliberate, selective targeting is now established.
Russian electronic warfare assets deployed in Crimea and near Rostov-on-Don can project GPS jamming capability across the Black Sea basin and into Bulgarian, Romanian, and Greek airspace — a coverage zone that encompasses multiple major European approach corridors.
The incident triggered EU-level and EASA discussions on mandating backup navigation systems, interference detection equipment, and electronic warfare countermeasures for civil aircraft — a regulatory consequence with potential fleet-wide implications across European commercial aviation.
The crew's successful reversion to ILS approach demonstrates that established contingency procedures functioned as designed. However, the incident exposes a structural vulnerability: modern aircraft operations — particularly in terminal areas — have become deeply dependent on GNSS for traffic sequencing, approach briefing, and cockpit situational awareness. An ILS reversion during a high-traffic approach sequence imposes non-trivial workload and coordination costs even when it is executed correctly. In conditions of degraded weather, high traffic density, or unfamiliar airport environment, the same interference could produce significantly more severe operational consequences. The safety outcome of this event was not guaranteed — it was the product of trained crew response against a threat vector that could easily have been more operationally complex.
Takeaway
The Von der Leyen GPS jamming event is not primarily a story about one flight. It is a story about a threat environment that had been building, measurably and trackably, for at least eighteen months — and whose signals were dispersed across NOTAMs, ADS-B anomaly databases, EUROCONTROL interference reports, and open-source geopolitical indicators, but never aggregated into a single, actionable risk score for the LBBB FIR and Plovdiv terminal area specifically. That aggregation gap is precisely what airspace risk intelligence platforms exist to close.
The incident also crystallises a threat pattern that is qualitatively different from incidental jamming: the deliberate, selective targeting of senior officials' aircraft as a tool of political signalling. This pattern requires threat modelling that integrates not just GNSS anomaly data but geopolitical event calendars, high-value flight tracking, and precedent databases of prior state-actor EW incidents. Standard NOTAM-based preflight briefing is structurally incapable of surfacing this class of risk.
This retrospective analysis examines signals present in public data before the event. It is provided for educational context only and does not claim predictive capability for future events.
FlySafe's continuous airspace risk monitoring for the LBBB FIR may have registered an elevated GNSS Interference Risk Score for the Plovdiv terminal area (LBPD) based on the convergence of three independent signal streams: (1) documented Russian EW coverage geometry placing Plovdiv within Crimea-origin jamming range, (2) the Baltic Shapps precedent coded as an active "VIP aircraft targeting" threat template in FlySafe's state-actor EW pattern library, and (3) the rising GNSS anomaly report frequency in Bulgarian airspace throughout Q2–Q3 2025. Flight planning through LBPD may have generated an automated advisory flagging GPS-dependent approach procedures as elevated-risk and recommending ILS-primary briefing as a pre-departure contingency — the exact procedure the crew was ultimately forced to execute reactively. For operators flying government or VIP missions into southeastern European terminals, FlySafe's geopolitical event correlation layer would additionally have flagged the von der Leyen itinerary as matching the target profile of prior confirmed state-actor EW events, warranting an enhanced threat briefing before departure.
The Plovdiv incident marks a threshold moment for how European aviation security is conceptualised. GPS jamming is no longer a peripheral concern associated with conflict-zone overflights — it is an active tool of state-level political coercion being deployed against specific, identifiable targets within nominally safe European airspace. Operators who continue to plan GNSS-dependent operations in the Black Sea, Baltic, and Eastern Mediterranean corridors without systematic interference risk assessment are accepting exposure to a threat category that regulatory frameworks have not yet fully priced in, but that geopolitical reality has made operational. The question is no longer whether your route crosses a war zone — it is whether your route, your passenger manifest, and your GNSS dependency profile make your aircraft an attractive EW target.
