Takeaways Up Front
1. Finland and Sweden flew their first joint air-defense scramble on September 24, sending Finnish Hornets and Swedish Gripens after a Russian formation over the Gulf of Finland.
2. The intercept was the first live use of an August arrangement that lets the two air forces fly joint missions and keep alert fighters on each other’s bases.
3. The Russian aircraft stayed in international airspace, Swedish officials said, and the mission came six days after Finland’s first F-35s landed at Rovaniemi.
Finland and Sweden flew their first joint fighter scramble on September 24, sending Finnish F/A-18 Hornets and Swedish JAS 39 Gripens to intercept and identify a Russian formation over the Gulf of Finland under the direction of a single Finnish operations center.
Finnish and Swedish Quick Reaction Alert (QRA) fighter jets were scrambled to intercept and identify Russian military aircraft in international airspace over the Gulf of Finland on 24 September 2026.

The Finnish Defence Forces called it the first joint operational identification mission by the two air forces. The Swedish Armed Forces said the Russian group consisted of a Tu-134 transport aircraft, MiG-31 long-range interceptors, and Su-30 multirole fighters flying in international airspace. Neither government reported a violation of national airspace.
One center, two air forces
Quick Reaction Alert, or QRA, keeps armed fighters fueled and ready to launch within minutes against aircraft that will not identify themselves. On September 24, a Finnish Air Operations Centre tasked Finnish and Swedish QRA fighters against the same target for the first time, rather than each nation working the intercept on its own.
“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,” said Colonel Vesa Mäntylä, Deputy Chief of Staff at Air Force Command Finland.
That cross-basing clause is the operational change. Alert fighters are normally tied to their home field, where fuel state, divert options, and response times are all measured. Letting Finnish Hornets stand ready in Sweden, or Swedish Gripens in Finland, redraws those calculations across one shared map.
The arrangement traces to an agreement the Finnish Defence Forces announced on August 28, under which Sweden contributes Gripen fighters and a Visby-class corvette, a small stealth surface warship, to the surveillance and protection of Finnish territory through at least the end of 2026.
The Swedish equipment strengthens air surveillance and frees Finnish forces to handle violations elsewhere. Sweden acted at Finland’s request because of the deteriorating security situation, Swedish Defense Minister Pål Jonson told Reuters.
A corridor watched from both shores
The Gulf of Finland is a narrow body of water with Finland on its northern shore, Estonia to the south, and Russian airspace closing its eastern end. Helsinki and Stockholm now monitor maritime and air traffic through this strategic region under an enhanced joint framework.
The Finnish Defence Forces maintain that no direct military threat is aimed at Finland. However, the conflict has occasionally spilled over into the region: several Ukrainian long-range strike drones targeting infrastructure inside Russia have strayed into Finnish territory. Official joint investigations confirmed that these drones were not aimed at Finland but drifted off course due to severe Russian electronic warfare and GPS jamming operating in the area.
Russian aircraft operate around the Baltic on a regular basis, and NATO fighters have scrambled repeatedly in recent weeks, including after a Russian Mi-8 helicopter crossed into Poland from Kaliningrad.
Finland joined NATO in April 2023 and Sweden in March 2024, adding roughly 832 miles of alliance land border with Russia along Finland’s eastern frontier.

The Hornets that flew the September 24 mission are on their way out. Finland’s first two F-35A Lightning II fighters landed at Rovaniemi on September 18, escorted by F/A-18 Hornets, opening a transition to a 64-jet fleet that will run alongside the Hornets until 2030.
