HELSINKI– Finland temporarily suspended all operations at Helsinki-Vantaa Airport (HEL) early Friday after authorities issued an emergency drone warning across the Uusimaa region.
The security alert prompted the Finnish Air Force to scramble Boeing F/A-18 Hornet fighter jets while several international flights were diverted to alternate airports in Sweden and northern Finland.
Airport operator Finavia halted traffic between 4:00 a.m. and 7:00 a.m. local time as authorities assessed a potential airspace threat near the Finnish capital.
Multiple long-haul arrivals operated by Finnair (AY) were affected, including flights from Tokyo, Osaka, Hong Kong, Singapore, and Malaga, forcing diversions to Stockholm Arlanda Airport (ARN) and Rovaniemi Airport (RVN).

Finland Scrambles F/A-18 Jets
The disruption began after Finland’s Ministry of the Interior issued an emergency public warning at 3:49 a.m., advising residents in the Uusimaa region to remain indoors.
Officials stated that at least one unidentified drone may have crossed into Finnish territory, though the exact number remained unclear during the initial stages of the incident.
Finavia confirmed that all departures and arrivals at Helsinki-Vantaa Airport were suspended for approximately three hours. Flight tracking data showed that two morning Finnair services from Tokyo diverted separately to Stockholm and Rovaniemi, while another inbound flight from Osaka also landed in Rovaniemi.
Flights arriving from Hong Kong, Singapore, and Malaga were redirected to Stockholm as authorities secured Finnish airspace. Rovaniemi, located in Lapland, frequently serves as an alternate airport for transpolar flights entering Finland from the north.
Operations gradually resumed after officials declared the threat over at 7:06 a.m. local time. Helsinki Airport restarted normal traffic shortly afterward, with Finavia confirming that the first post-closure movements began around 7:19 a.m, AeroTime flagged

Finnish Fighter Response
During the alert, Finnish Air Force Boeing F/A-18 Hornet fighters were observed operating over the Helsinki coastline and across southern Finland. The aircraft were deployed as part of heightened surveillance measures after authorities identified a possible threat corridor between Helsinki and Porvoo.
Conflicting statements later emerged from Finnish agencies regarding whether drones had actually entered national airspace. Kimmo Kohvakka, Director General for Rescue Services at the Ministry of the Interior, stated that officials believed at least one drone had crossed into Finland.
However, Finnish Defence Forces communications specialist Henrik Gahmberg reportedly said the military had not visually confirmed any drone activity inside Finnish territory.
Defence officials did not immediately explain the discrepancy between the two statements.
Finland is currently transitioning away from the F/A-18 Hornet fleet, with the aircraft scheduled to be replaced by 64 Lockheed Martin F-35A Lightning II fighter jets beginning this year.

Baltic Airspace Tensions
The incident comes amid growing security concerns across the Baltic and Nordic airspace linked to suspected Ukrainian drone operations targeting Russian infrastructure near the Gulf of Finland.
Authorities in neighboring Latvia also issued a temporary overnight airspace warning during the same period.
Finnish President Alexander Stubb later stated that Finland faced no direct military threat, while Prime Minister Petteri Orpo confirmed that the Defence Forces had intensified surveillance and preventive measures following the incident.
Although officials eventually declared the situation safe, Friday’s disruption highlighted the increasing operational challenges European aviation authorities face as regional geopolitical tensions spill into civilian airspace management.
