On the night of September 22, 2025, Copenhagen Airport was shut down for nearly four hours due to three large drones overflying the airport. Norway's Oslo Airport also closed for three hours after a single drone was spotted. Danish authorities suspect that three Russian-linked ships – Astrol 1, Pushpa/Borocay, and Oslo Carrier 3 – were used as launch platforms or decoys for the drone raid. These vessels have prior suspicious activity linked to Russian interests. The attack was described as professionally executed and provocatively ostentatious. Danish Prime Minister Mette Frederiksen called it the most serious attack on Danish critical infrastructure to date and did not rule out Russian involvement. Similar drone attacks and Russian airspace violations occurred around the same time in Estonia and Poland. Investigations are ongoing, with difficulties expected in proving direct involvement due to the ease of disposing of drone launch equipment and rapid transfer of personnel between vessels. This incident follows a recent German case where a Russia-linked ship was suspected of launching drones for reconnaissance and sabotage.
