Russia Deploys 36 GPS Spoofing Transmitters to Redirect Ukrainian Drones Into NATO Airspace

BLUFRussia's 12-fold GPS spoofing expansion from Kaliningrad will likely force additional Ukrainian drone incursions into NATO airspace before late July, compelling unilateral allied shoot-down decisions Moscow can exploit.

Darius Kuliesius, deputy head of Lithuania's communications regulator, told Reuters on May 26 that Russia expanded GPS spoofing antennae in Kaliningrad from three to 36 since early 2025, with range now reaching 450 kilometers 12. Researchers from Gdynia Maritime University and the University of Colorado traced Baltic interference to two Kaliningrad coastal sites near Okunevo and the Baltiysk naval base 2. A Ukrainian drone struck a Latvian oil depot on May 7; on May 19, a Romanian F-16 shot down a drone over Estonia that Kyiv attributed to Russian spoofing, the first allied shootdown of a drone believed to be Ukrainian 2. Ukrainian Foreign Minister Sybiha stated Ukraine's investigations proved Russian electronic warfare deliberately diverted the drones from their targets; Russia has denied responsibility 23.

Analysis
The 12-fold transmitter expansion in Kaliningrad has shifted GPS denial from episodic to permanent, and additional diverted drone incursions into NATO airspace are likely before July 31. Without a coordinated alliance engagement framework, each incident forces member governments into unilateral shoot/no-shoot decisions on unidentified aircraft, the operational ambiguity Moscow's operations require. Geolocated technical reporting from Lithuanian regulators and academic researchers provides consistent triangulation on range and siting, the basis for moderate confidence; Ukraine's pace fielding spoofing-resistant airframes is the primary residual uncertainty. Navigational limitations intrinsic to Ukrainian long-range airframes remain an untested competing explanation, since post-crash forensics have not been made public. A further incident before July 31 forces NATO's Baltic air-policing command to formalize escalation thresholds currently deferred to national capitals.
