Aviation News – The Swedish Air Force’s iconic “flying Christmas tree” tradition expanded across borders this year, with Denmark and Finland joining a multinational formation flight over Scandinavia, highlighting regional cooperation and public engagement.
The annual event, known in Sweden as Julgransflygning, features fighter jets flying in a Christmas tree-shaped formation over major cities. Long a Swedish tradition, the spectacle has now inspired neighboring countries, marking a symbolic step in closer Nordic defense and cultural collaboration.
On December 16, 2025, Swedish Saab JAS 39 Gripen fighters flew alongside Danish F-35s and an F-16 in coordinated formations over Denmark and southern Sweden. Aircraft launched from multiple air bases, including Ronneby in southern Sweden. Due to challenging weather conditions, the jets were unable to complete the entire planned route.
The flight required precise coordination, tight timing, and bolt-tight formation discipline to maintain the distinctive tree shape across international airspace. Beyond its visual appeal, the operation demonstrated interoperability between different aircraft types and air forces, reinforcing readiness and joint operational capability.
“The flying Christmas tree is a traditional and memorable element for us fighter pilots,” said Martin Lindström, formation leader of the Swedish Air Force from Ronneby. “We are grateful for the public’s involvement and appreciation and look forward to flying together.”
Looking ahead, the inclusion of additional Scandinavian air forces signals growing interest in expanding the tradition, potentially making it a regular multinational event. It also serves as a visible reminder of regional unity and shared values during the holiday season.
The cross-border Christmas tree flight blends tradition, precision flying, and international cooperation into a unique annual display. As more nations take part, the event is likely to grow in scale and significance, strengthening both public connection and military partnership across Scandinavia.
