Russian Su-35 and other combat aircraft intercepted over the Baltic Sea after violating NATO flight rules.

NATO fighter jets deployed as part of the Baltic Air Policing mission intercepted a Russian aerial formation that included Su-35 multirole fighters along with Su-30 and MiG-31 combat aircraft after they flew near NATO airspace without proper flight plans or active transponders. The Russian aircraft, tracked by NATO radar, were identified approaching the airspace adjacent to Estonia and Lithuania, prompting allied fighter jets to scramble and establish visual contact to monitor the formation’s movements. NATO spokespeople said the intercept was conducted in international airspace but stressed that the lack of radio communication, transponder codes and flight plans elevated safety and hybrid-warfare concerns among alliance states. Estonian and Lithuanian defence officials reiterated that such flight behaviour – especially by advanced fighters like the Su-35 – tests NATO air-defence response times and readiness, even when no formal airspace breach is officially recorded. Allied jets accompanied the Russian formation until it returned toward Kaliningrad and Russian border regions, after which they stood down. NATO defence officials emphasised that these incursions and approaches near allied territorial airspace fit a pattern of hybrid pressure tactics that blend military probing with ambiguous intent below the threshold of conventional conflict. The presence of Su-35S fighters – including ones from aerobatic or demonstration units repurposed for operational missions – underscores Moscow’s practice of deploying its modern air platforms in ways that can generate uncertainty among NATO members. Russia’s Defence Ministry routinely denies violations, describing its flights as routine training or transits in international zones, though the absence of transparent communication has repeatedly drawn allied protests.
