Romanian military divers detonated two drifting Gerbera-type maritime drones near the Neptun Deep offshore gas project in the Black Sea on Aug. 11, 2026, after a civilian construction vessel spotted them roughly 90 nautical miles east of Constanța inside Romania’s exclusive economic zone. Defence Minister Radu Miruta confirmed the controlled explosions, while Ukraine said the drones were not operated by its forces. Neptun Deep, jointly developed by OMV Petrom and state-owned Romgaz, is projected to become the European Union’s largest offshore gas development when production begins in 2027. The incident follows a series of 2026 incursions, including three unauthorized Russian drones shot down by Romanian F-16 jets in July, raising concerns for critical infrastructure in NATO-member Romania.
