On 15 May 2026, the Finnish Defence Forces immediately enhanced their surveillance and countermeasure capabilities upon receiving information of potentially misleading drones heading towards Finland. Measures included increased air surveillance personnel, intensified fighter jet readiness with adjustments to their locations, duty times, and launch preparedness. The Army helicopters and Navy vessels were also deployed more intensively. The Border Guard increased its readiness. A temporary aviation restriction zone was established from 04:00 UTC onwards between Helsinki and Porvoo to ensure civilian safety and facilitate safe neutralization of the drones. Helsinki-Vantaa air traffic and Gulf of Finland maritime traffic were rerouted accordingly. Rescue authorities issued a hazard warning for the Uusimaa region at 01:49 UTC. Finnish officials stressed there is no direct military threat to Finland at present but noted that Ukraine’s extensive drone attacks against Russian territory have caused some drones to stray into Finnish airspace. The strikes against Russia are ongoing with no immediate end in sight.
