In late March 2026, three Ukrainian drones accidentally entered Finnish airspace during a large Ukrainian drone attack on Russian oil terminals nearby. Finnish Defence Forces have stepped up monitoring with mobile targeting radars like the American Raytheon system in Kouvola, capable of detecting drones up to 75 km away, although drone detection is affected by technical and environmental factors. The border guards detected a drone armed with an explosive warhead on the ice of Lake Pyhäjärvi in Karelia; other drones fell near Kouvola. Defence Forces policy restricts shooting down drones over populated areas or towards Russia to prevent escalation. Since the incident, no foreign drones have been detected. Colonels emphasized readiness to intercept threats near the capital with fighter jets. This incident highlighted challenges in drone detection and neutralization at Finland's borders amid regional drone warfare.
