Fighter jets operating under NATO's Baltic Air Policing mission shot down a foreign drone in Latvian airspace on Friday, the latest in a mounting series of incursions that underscore the security burden Europe's eastern flank continues to bear in the fourth year of Russia's full-scale invasion of Ukraine.
The Latvian armed forces said the drone entered Latvia as a result of Russian electromagnetic warfare and was intercepted over the Balvi region in the east of the country. Latvia's military has deployed additional air defence units to its eastern borders and warned that "as long as Russia's aggression in Ukraine continues, a recurrence of cases where foreign drones enter or approach Latvian airspace is possible." Further airspace threats were identified in the municipalities of Augšdaugava, Preiļi, Rēzekne, Balvi and Alūksne, but these have since ended.
The Eastern Flank Under Pressure
The interception comes amid mounting drone incursions into NATO airspace along the alliance's eastern flank, which remains particularly vulnerable to security challenges arising from Russia's war in Ukraine. Russia launched its full-scale invasion of the country in February 2022. In July, Romanian fighter jets shot down three drones over just three days amid a surge in drone-related incidents in the country. The Romanian Prosecutor General's Office determined that at least one of the intercepted drones was of the Shahed-type used by Russian forces in its war against Ukraine, officials have said.
Romanian military divers also destroyed two Gerbera-type drones in the Black Sea this week, close to the Neptun Deep gas project. Romanian Defence Minister Radu Miruță said at the time, "To ensure the safety of the shipping lane and the work being carried out around the platform, the decision was taken to carry out a controlled destruction by detonation." In June, a Ukrainian sea drone exploded in the Romanian port of Constanta after the Ukrainian military said it had veered off course as a result of Russian electronic warfare interference. Another drone exploded close to a compressor station of the Trans-Balkan gas pipeline in Bulgaria last week.
NATO's Response and Defence Costs
NATO allies gathered this week to discuss the recent drone incursions and incidents, signalling their full solidarity with and support for the affected Allies. NATO said in a statement, "Allies reiterated that Russia bears full responsibility for the airspace violations, which are dangerous and unacceptable, and demonstrate Russia's increasing tolerance for risk," adding that it "stands ready to deter and defend against any aggression."
NATO's Baltic Air Policing mission sees allies deploy in four-month rotations to air bases at Šiauliai in Lithuania and Ämari in Estonia, where they can be called into action by the NATO Combined Air Operations Centre in Uedem, Germany. Latvia, Lithuania and Estonia, as host nations, provide air command and control infrastructure and personnel for the mission, which was initially launched 22 years ago and was expanded 12 years ago following Russia's illegal annexation of the Crimean Peninsula.
Why This Matters:
The escalating drone incursions along NATO's eastern border reveal the sustained security burden that Baltic and Black Sea member states carry on behalf of the entire alliance. These aren't isolated incidents — they're a pattern of Russian aggression that forces nations like Latvia, Romania, and Bulgaria to maintain constant vigilance and deploy costly air defence systems. The Baltic Air Policing mission, now in its third decade, was conceived as a temporary measure for states without their own fighter capabilities. It's become a permanent fixture of European defence architecture, paid for through allied rotations that demand continuous military investment. As Russia's electronic warfare capabilities grow more sophisticated and its tolerance for risk increases, Europe's eastern members face a choice: either NATO commits to permanent, robust air defence infrastructure in the region, or individual nations must shoulder even greater defence spending to protect critical infrastructure like gas pipelines and energy projects that serve the entire continent.
