Estonia has formally requested consultations under NATO’s Article 4 after three Russian MiG-31 fighter jets violated its airspace over the Baltic Sea on Friday. The incident, which lasted about 12 minutes near Vaindloo Island, has been deemed by Estonian officials as “unprecedentedly brazen,” adding to mounting tensions between NATO and Russia.

According to Tallinn, the aircraft entered without filing flight plans, had their transponders switched off, and failed to communicate with air traffic control. NATO scrambled Italian F-35 jets, stationed in Estonia as part of the alliance’s Baltic air policing mission, to intercept the intrusion.

Estonia’s Foreign Minister Margus Tsahkna condemned the breach, saying it was the fourth Russian violation of Estonian airspace this year, but by far the most serious in terms of scale and intent. Prime Minister Kristen Michal echoed the urgency of the situation, saying that such provocations require a strong, coordinated response from NATO allies.

In response, Estonia summoned the Russian chargé d’affaires and lodged a formal protest. The government also officially triggered Article 4 consultations, seeking to convene NATO’s North Atlantic Council to review the incident and discuss collective security implications. Article 4 allows for talks when any member believes the territorial integrity, political independence, or security of another member is threatened, though it does not automatically generate a military response.

Russia has denied violating Estonian airspace. According to a statement from its Defence Ministry, the three MiG-31s flew over neutral waters en route to Kaliningrad, claiming they remained on their agreed flight path and did not violate any border.

The incident comes amid a pattern of provocative maneuvers and airspace incursions by Russia, including drone violations in neighboring Poland and other NATO states in recent days. Analysts warn these actions may be testing NATO’s readiness and the cohesion of its eastern defense posture.

As NATO prepares for the upcoming meetings of its North Atlantic Council, Estonia is urging its allies to work on strengthening air defense capabilities, enhancing monitoring, and ensuring that any violation is met with unified diplomatic and, if necessary, defensive responses. Whether this latest invocation of Article 4 will lead to new operational steps or deeper defense commitments remains under close watch.
