Estonia has begun deploying its first fixed drone detection and monitoring systems along its Russian border as the Baltic state continues to strengthen its defences against aerial incursions linked to the war in Ukraine.

The systems have been installed across three sections of the border between the Luhamaa crossing and the tri-border area where Estonia, Latvia, and Russia meet. Additional installations are planned later this year as part of a broader effort to create a nationwide drone monitoring network.

“We are working toward establishing a drone network that covers all of Estonia,” Interior Minister Igor Taro said in a statement announcing the deployment. The ministry also added a number of mobile radar systems that can be moved along the border to shore up defenses. According to Estonian state media outlet EER, the fleet cost ?1.3 million while the first anti-drone systems cost ?300,000 thus far.

The move follows a series of drone-related incidents across the Baltic region. On 19 May, a suspected Ukrainian drone entered Estonian airspace before being shot down by a Romanian F-16 operating as part of NATO’s air policing mission. The incident highlighted the growing challenge posed by drones operating near alliance borders and reinforced concerns about the spillover effects of the conflict in Ukraine.

Estonia is not alone in facing the issue. Lithuania and Latvia have also reported multiple drone incursions in recent months, with several aircraft believed to have originated from operations connected to the war in Ukraine. The incidents have intensified discussions across the region about airspace security, early warning systems, and the need for stronger counter-drone defences. Poland also saw one reported incursion last year.

“Today we are only seeing the first stage on the southeastern border, where we have anti-drone detection and surveillance capabilities in operation. This must cover the entire land border. At the end of June, we will also open the first stage in the Narva area. Ultimately, we must have the entire eastern border covered with anti-drone capabilities, not just the eastern border, but in fact all of Estonia,” said Minister Taro.
