Baltic States in September 2026: the most important developments in security
Security in the Baltic states in September 2026 was dominated by drones, airspace incidents and a debate over nuclear deterrence.
Estonia blamed Russia for an arson attack on the defence firm Milrem; three Latvian suspects were extradited to Estonia and remanded in custody. Drones were a recurring theme. Latvia and Estonia issued airspace warnings after drones approached their borders, drones crashed in Latvia while a Dutch minister visited the border, and Latvia reported a migrant tunnel and a drone from Belarus. On 15 September an Italian NATO fighter jet shot down a suspected Russian drone over Lithuania; NATO and Lithuania's defence minister said it likely came from Russia, and Vilnius airport briefly halted flights. An Estonian minister called it a first for the NATO Baltic air policing mission. Latvia's foreign minister Rinkēvičs said the country lacks border guards. Ukraine attacked Russia's Ust-Luga port with 52 drones while NATO jets scrambled over Estonia.
Nuclear deterrence was another focus. Estonia's prime minister said the country is in talks to join France's nuclear deterrence. Russia's foreign ministry said it would respond accordingly if Lithuania moves to field nuclear weapons, and the Kremlin warned Lithuania over the proposal. On 22 September Lithuania's State Defence Council decided to drop the country's ban on hosting nuclear weapons, and Vilnius has not announced plans to station any. Two US Army battalions are to arrive in Lithuania in October.
Lithuania signed a drone production agreement with a US company, and the Baltic states asked the EU for 500 million euros for drone defence. Latvia will send up to 20 soldiers to clear Hormuz. A Russian ship fired flares at a Danish helicopter in the Baltic region. Latvia held its Namejs 2026 military drills.
