NATO fighters from six Alliance countries were scrambled on Monday April 20 to intercept a significant Russian air formation over the Baltic Sea. According to the French military contingent based in Lithuania under NATO’s Baltic Air Policing mission, the Russian flight involved two Tu-22M3 strategic bombers — NATO designation “Backfire” — escorted by approximately ten Su-30 and Su-35 fighters. The formation flew for more than four hours over neutral waters of the Baltic.

Nations that scrambled fighters in response included Sweden, Finland, Poland, Denmark, Romania and France — with French Rafales from the Lithuania-based Baltic Air Policing detachment among those that rose to intercept. The Russian Ministry of Defence confirmed the flight was planned and said it complied with international rules for flight over neutral waters. NATO noted that such interceptions occur regularly and that Russian aircraft frequently do not use transponders, do not contact air traffic control and do not file flight plans — practices that force Alliance nations to scramble regardless of the stated purpose of the flight.

The Tu-22M3 Backfire is Russia’s primary long-range maritime strike and land-attack bomber. It carries cruise missiles, anti-ship missiles and conventional or nuclear gravity bombs with a combat radius that covers all of NATO’s Baltic and Nordic flanks from Russian bases without mid-air refuelling. Russia has used the Tu-22M3 extensively in Ukraine — it was a Tu-22M3 strike that killed dozens in the Kremenchuk shopping centre attack in 2022, and the aircraft has been used in multiple high-profile strikes on Ukrainian cities. Several have been lost to Ukrainian air defences during the war.

Flying two Backfires with a ten-aircraft Su-30/Su-35 escort is an unusual force package for a routine training flight. The escort-to-bomber ratio suggests either a deliberate show-of-force mission or an exercise designed to test the reaction time and identification procedures of NATO’s Baltic Air Policing network — now staffed by six nations simultaneously following Finland and Sweden’s accession to the Alliance.

The timing of this mission — on the day before the Islamabad II Iran-U.S. talks and with global attention focused on the ceasefire deadline — is not incidental. Russia has consistently used periods of concentrated Western attention on other theatres to probe NATO’s eastern flank. The Baltic has been a primary test arena: Russian aircraft have increasingly avoided transponder use and air traffic control contact, forcing Alliance nations into repeated interceptions that confirm response times, coordination procedures and coverage gaps.

The six-nation response is itself significant. Sweden and Finland’s full integration into Baltic Air Policing since their NATO accession has substantially deepened the Alliance’s coverage in the High North and Baltic approaches. The combination of Polish, Romanian, Danish, Swedish, Finnish and French fighters responding to a single Russian formation demonstrates a coordinated multi-national capability — but also underscores how much Alliance airspace management depends on constant vigilance against an adversary that routinely flies without transponders in one of the world’s busiest civil aviation corridors.
