The incident adds to a series of aerial provocations reported by NATO allies since the start of Russia’s full-scale invasion of Ukraine in 2022 as Moscow is suspected of using the aircraft to spy on the alliance’s positions.

Russian aircraft often fly without using transponders, failing to file flight plans, and do not establish contact with regional air traffic control — a pattern that NATO officials have long described as high-risk behavior.

European allies have repeatedly warned that Russia’s ongoing aerial provocations could lead to a dangerous escalation if not firmly countered.

In previous incidents, Russian aircraft have taken off from Kaliningrad, headed west toward international airspace near Poland, [Germany](https://kyivindependent.com/tag/germany/), Sweden, and Denmark.

In addition to the flights, Russian sabotage efforts have escalated drastically in the Baltic Sea region since the outbreak of full-scale war in 2022. Russia ‘shadow fleet’ vessels have been suspected of deliberately damaging undersea power cables as a means of disruption on the European continent.
