Romanian officials said no one was injured, but they are still investigating the circumstances after a Ukrainian sea drone exploded in Constanta harbor on Friday morning. Reports from Ukraine are blaming Russian jamming for taking the drone off course.

The Ukrainian Armed Forces confirmed they had lost control of the sea drone, which they said ended up off the coast of Romania. They reported that they had advised the military and maritime forces of Romania to prevent civilian injuries.

The circumstances behind the deployment and loss of the drone, however, remain unclear. Constanta, the main seaport in Romania, is more than 80 miles south of the border with Ukraine in southern Romania.

Romanian officials said the drone had been discovered at around 0550 this morning, June 5, and it had appeared to become wedged in berth 78 of the civilian port, near the headquarters of the Romanian Agency for Saving Human Life at Sea (ARSVOM) and other official buildings. The authorities ordered an evacuation of the area as a precaution.

They were surveying the drone and looking to deactivate it when it self-detonated. Port cameras caught images of a large water plume and possibly some damage to the surrounding infrastructure.

 

 

 

 

There was speculation, however, that the drone might have been using a form of automated targeting designed to hone in on Russian energy infrastructure. Romanian media said the drone was only a few hundred meters from the oil terminal in Constanta.

Concern was also raised by unconfirmed reports that up to four other drones had also been spotted. Romanian officials ordered up to 1,000 people to leave the Black Sea beaches. Reports said two helicopters and a boat were scouring the coastline. Romania said its highest-level emergency response protocol was in place, but later statements said that there was no further danger at this time.

“The circumstances under which the drone reached the port and any additional risks are currently under investigation,” said Romanian President Nicusor Dan. Ursula von der Leyen, President of the European Commission, also released a statement expressing concern over the spread of hostilities and the impact on NATO countries. Turkey had earlier this week again cautioned about the spread of the hostilities into wider areas of the Black Sea after reports of drone attacks on additional tankers.

Unsubstantiated claims in the Ukrainian media cited electronic jamming by the Russians. There were claims that Russia is intentionally redirecting Ukrainian drones to target NATO countries.

Constanta is a sprawling industrial port covering approximately 20 miles. It has 156 berths and is a regional commercial hub. Ukraine has used Constanta as an alternate due to its connections to the Danube when Ukraine’s ports came under heavy attack.

Unconfirmed reports said that Romanian forces had discovered another drone on Wednesday offshore in the Black Sea. They also indicated that Romanian forces have neutralized nine sea mines, with a total of 156 mines having been discovered in the Black Sea since the start of the war in Ukraine.

Last week, a Russian aerial drone also went off course and struck an apartment building in the Romanian city of Galati, injuring two people. Romanian officials called on NATO to provide the country with stronger air defenses and anti-drone systems. 
 

Video Shows Extensive Blast Damage Aboard Russian Corvette

New video footage of this week's Ukrainian strike on a Russian corvette has emerged, and it suggests a more extensive level of damage than previously expected. 

On Wednesday morning, Ukrainian Unmanned Systems Forces (USF) drones attacked the Kronstadt naval base near St. Petersburg and hit the corvette Boikiy - a workhorse of the Baltic Fleet and a regular presence on Russian Navy escort runs in the North Sea and English Channel. Thge ship has often been spotted providing cover for the Russian "shadow fleet" of unregulated tankers and the well-known "Syrian Express" cargo service to Tartus. 

The corvette was hit during a yard period, a vulnerable time for a warship, and at least one drone struck her top deck just aft of the wheelhouse, next to the mainmast. Post-casualty satellite footage showed multiple firetrucks spraying down her topsides, and apparent charring on the superstructure. 

On Thursday, unverified on-scene footage from the dockside was posted on social media - an unlawful act in the Russian Federation - and it appeared to show significant blast and fire damage on the top deck of the corvette. Amidst flames and smoke, the remains of the mainmast were visible, but not in an upright position; the mast was laying on deck and protruding out over the side of the ship. 

Separately, Ukraine's USF reported Thursday that its forces hit a Svetlyak-class border patrol ship (Project 10410) of the Russian Border Patrol overnight Wednesday. The strike happened off the coast of Yurkyne, a small settlement on the Sea of Azov side of the Crimean peninsula, northwest of Kerch Strait. Project 10410 patrol vessels are used for port protection and point air defense, and carry antiaircraft cannons and a naval gun. Footage shows that the drone struck its target while the vessel was under way.
