A sea drone detonates inside Constanta, and Black Sea drone warfare reaches a NATO port
A maritime drone of the type Ukraine uses against Russia's Black Sea Fleet blew up inside Romania's largest port during inspection, no casualties, pulling NATO soil into the Black Sea drone war.
A maritime drone of the type Ukraine uses against Russia's Black Sea Fleet blew up inside Romania's largest port during inspection, no casualties, pulling NATO soil into the Black Sea drone war.
A naval drone exploded inside Romania's Black Sea port of Constanta on Friday morning, the Defense Ministry said. Specialists had pulled it from the water and were trying to make it safe when it detonated at berth 78 at 10:28 a.m. local time, Turkiye Today reported. No casualties were reported.
The ministry said the drone was "of the type used in the war in Ukraine" and was not Romanian equipment. Broadcaster Digi24, citing military sources, identified it as a Magura V5, a Ukrainian sea drone that has struck Russian Black Sea Fleet ships, Anadolu Agency wrote. Romanian authorities said they had not established the drone's origin.
Deputy Interior Minister Raed Arafat said his office learned the device might explode only minutes before it did, and that the area was already evacuated. Romania widened the evacuation one kilometer inland across Constanta and Tulcea and sent SMURD and Black Hawk helicopters to search the coast for more drones. "If there was one, there could be others," Arafat said.
Constanta is the EU's and NATO's main Black Sea port and a transit hub for Ukrainian grain. About a week earlier, a drone hit a residential building in Galati, on Romania's border with Ukraine. The Magura is a Ukrainian weapon used against Russia's fleet, so a live one inside an Alliance port extends the Black Sea drone war onto NATO territory.

Frequently Asked Questions
What exactly happened in Constanta?
A naval drone self-detonated at berth 78 of Romania's Constanta port at 10:28 a.m. on June 5, 2026, after it was spotted around 6 a.m. and recovered for inspection, per Turkiye Today and Anadolu Agency. No casualties were reported.
Whose drone was it?
Romania's Defense Ministry said only that it was "of the type used in the war in Ukraine" and not Romanian equipment. Broadcaster Digi24, citing military sources, identified it as a Ukrainian Magura V5, per Anadolu Agency. Authorities have not confirmed its origin or how it reached the coast.
What is a Magura V5?
It is Ukraine's signature uncrewed surface drone, an explosive-laden boat that has sunk and damaged ships of Russia's Black Sea Fleet, as referenced in the Digi24 identification reported by Anadolu Agency.
Why does it matter that this happened in Romania?
Constanta is the EU's and NATO's main Black Sea port and a logistics node for the Alliance's eastern flank. A Ukrainian-type sea drone detonating there, about a week after a drone hit a building in Galati, extends the Black Sea drone war onto NATO soil, per Turkiye Today.
Could there be more drones?
Deputy Interior Minister Raed Arafat said the suspicion of additional devices was "legitimate," prompting a one-kilometer coastline evacuation across Constanta and Tulcea and a helicopter search of the shore, per Turkiye Today.
