On the afternoon of 19 September 2025, Estonia’s Defence Forces reported that three Russian MiG-31 fighter jets entered Estonian airspace for approximately twelve minutes before being intercepted by NATO forces. The incursion occurred over the Gulf of Finland near Estonia’s northern maritime approaches, a key zone linking Baltic and Russian waters. The dynamic fits hybrid-warfare logic: the violation tests response times, imposes readiness costs, and signals adversary resolve without triggering full-scale war. Estonia immediately invoked NATO consultations (via Article 4) and coordinated with allied air-defence assets to monitor the activity. Though the Russian state denied that its aircraft violated Estonian air-space, the incident heightened Tallinn’s threat assessment and led to increased allied air-patrol presence over the Baltic region.
