Russia expands electronic warfare corridor along Finland border, NATO confirms signal jamming affecting civilian aviation
NATO's Supreme Headquarters Allied Powers Europe (SHAPE) confirmed on 10 July that Russia has significantly expanded its electronic warfare corridor along the Finnish border. Persistent GPS spoofing and jamming now affect civilian aviation from the Gulf of Finland to northern Karelia. The Finnish Transport and Communications Agency (Traficom) recorded 847 GPS anomaly events in June 2026, a 220% increase on the monthly average for the first quarter. Commercial flight navigation, shipping in the Gulf of Finland and overland logistics in eastern Finland have all been disrupted. NATO is working with Finnish authorities on the legal and operational response options under Article 3 of the North Atlantic Treaty. If you run logistics, travel management or security operations in the area, don't rely on GPS alone. Have backup positioning, pre-planned alternative routes and clear communications procedures ready for when navigation degrades.
