Finland Sweden joint fighter scramble

Finnish and Swedish quick reaction alert fighters intercepted and identified a group of Russian military aircraft over the Gulf of Finland on September 24, 2026. The Finnish Defence Forces described it as the first joint operational identification mission flown by the two air forces, directed from the Finnish Air Force’s Air Operations Centre. A tweet from the Finnish Air Force on September 25 confirmed the scramble in international airspace. The mission involved Finnish F/A-18 Hornets and Swedish JAS 39 Gripens.

The Russian formation consisted of a Tupolev Tu-134 transport aircraft, Mikoyan MiG-31 fighters, and Sukhoi Su-30 fighters. The Swedish Armed Forces also released a statement on September 25. This mission is part of the two nations' cooperation in the surveillance and protection of territorial integrity.

Deepened cooperation enables cross-base operations

The mission was made possible by recently deepened cooperation allowing QRA fighter jets to operate from each other's air bases. Colonel Vesa Mäntylä, Deputy Chief of Staff at Air Force Command Finland, stated: "The deeper cooperation that began this autumn enables joint identification missions and allows QRA fighter jets to operate from the other country’s air bases." Alert fighters from both countries normally stand QRA duty at their national bases but may operate from the other country’s bases when necessary.

Major General Jonas Wikman, Commander of the Swedish Air Force, said the event shows close cooperation in practice. He noted it was built over years on trust and strong personal relationships. Cross-basing rights are now in place. Joint operations with cross-basing shorten response times across the shared Baltic approach.

Russian aircraft intercepted in international airspace

The intercepted Russian detachment was flying in international airspace over the Gulf of Finland. The aircraft types involved are detailed in NATO reporting nomenclature.

Context of broader Nordic and NATO integration

The joint mission fits within expanded Nordic Air Power cooperation and NATO integration. Military integration between the two air forces has accelerated since both countries joined the alliance. Finland became a member of NATO on April 4, 2023. Sweden followed on March 7, 2024. The two air forces also cooperate with Norway and Denmark through Nordic Air Power, developing interoperability as part of NATO’s collective defence.

Finnish and Swedish fighters have flown Cross Border Training sorties almost weekly for several years. In the Baltic Sea region, they cooperate with NATO Baltic Air Policing detachments. The Finnish Defence Forces linked the reinforced cooperation to Ukraine’s long-range drone strikes against Russia. Individual drones had strayed into Finnish airspace and territory. The attacks on Russia were not expected to end in the near future.

Finland has recorded several airspace incidents in 2026. Helsinki-Vantaa Airport halted traffic for three hours on May 15 following a regional drone warning. On August 21, the Finnish Border Guard declared that a Russian Il-20 reconnaissance aircraft had flown nearly nine kilometers into Finnish airspace south of Utö the previous day.

In late August, Sweden's government ordered military units, including JAS 39 Gripen fighters and naval vessels, to patrol areas along Finland's border with Russia. The deployment followed a direct request from Finnish authorities and rested on bilateral agreements giving Swedish forces a mandate to help defend Finnish territory. It was amid repeated Russian airspace violations tied to the war.

The decision to deepen cooperation in protecting Finland’s territorial integrity was announced on August 28, 2026. Under the arrangement, Sweden contributes JAS 39 Gripen fighters and a Visby-class corvette in the Baltic Sea region. The Swedish assets are intended to strengthen air surveillance and free up Finnish resources. The cooperation is set to continue until at least the end of 2026.
