The Baltic states are facing growing concern after a series of drone-related incidents in which unmanned aerial vehicles have violated the airspace of Lithuania, Latvia and Estonia in recent weeks. Although some of the aircraft have been described as Ukrainian or likely Ukrainian drones that veered off course during attacks on targets in Russia, there is a growing conviction in the region that Moscow bears political and strategic responsibility for the escalation. Baltic capitals point to Russian electronic interference, hybrid operations and attempts to test NATO’s resilience.
The most tense scenes unfolded in Lithuania in recent days. After a drone was detected entering the country’s airspace, air and rail traffic in Vilnius was suspended, while some politicians and residents were directed to shelters. According to Reuters, Lithuanian services activated emergency procedures, and NATO aircraft taking part in the Baltic Air Policing mission were also scrambled.
Latvia has felt similar pressure. In early May, Latvian armed forces reported that foreign drones had entered the country’s airspace from the direction of Russia, and that two drones had crashed in Latgale. An air threat was declared in the areas of Balvi, Ludza and Rēzekne, while residents were urged to remain indoors, close windows and doors, and avoid approaching suspicious objects. In some places, school classes were cancelled or moved online.
Latvian public media reported that one of the drones struck a petroleum products storage facility in Rēzekne. According to a representative of the Latvian armed forces, the aircraft had a warhead, although the authorities stressed that at the early stage of the investigation it was not possible to determine either the exact type of drone or its origin. NATO fighter jets were in the air during the incident, but no weapons were used due to concerns for the safety of civilians and infrastructure.
Estonia has also been affected by similar incidents. In March, a drone hit the chimney of the Auvere power plant, although it did not disrupt energy supplies. According to the Centre for Eastern Studies, the incidents in Estonia, Latvia and Lithuania may have been linked to Ukrainian attacks on Russian fuel infrastructure near the Gulf of Finland, with the drones most likely drifting off course as a result of Russian electronic warfare measures.
The problem, however, goes beyond individual border violations. For Lithuania, Latvia and Estonia, every such incident is a test of early warning systems, air defence, crisis communication and coordination with NATO. Drones are harder to detect and neutralize than traditional aircraft, especially when they fly low, are small in size or follow unpredictable routes. As a result, the Baltic states are increasingly asking whether their current air defence capabilities are sufficient if such incidents continue.
An additional element of pressure is Russia’s information narrative. Moscow has accused the Baltic states of allegedly allowing Ukraine to use their airspace to launch attacks on Russia. The foreign ministers of Estonia, Latvia and Lithuania rejected these accusations as completely baseless, stressing in a joint statement that the Baltic states have never allowed their territory or airspace to be used for drone attacks on targets in Russia.
In practice, this means that drones have become not only a tool of the war in Ukraine, but also a source of tension along NATO’s entire eastern flank. Even if some of the aircraft are not deliberately sent against the Baltic states, their appearance over allied territory has a political effect: alarms, public anxiety, pressure on governments and questions about the credibility of air defence.
For NATO, the situation in the Baltic states is a warning. The line between conventional war, an accidental incident and hybrid action is becoming increasingly blurred. That is why Vilnius, Riga and Tallinn expect from their allies not only declarations of solidarity, but also a real strengthening of counter-drone, radar and air defence systems.
The series of incidents shows that the security of the Baltic region today depends not only on tanks, brigades and traditional defence systems, but also on the ability to quickly detect and neutralize small unmanned aircraft. It is drones — cheap, difficult to track and vulnerable to interference — that have become one of the most troubling symbols of a new stage of the war and of pressure on NATO.
