The cargo vessel caught fire and sank in Romania’s exclusive economic zone, but the cause of the suspected strike and those responsible have not been established
The general cargo vessel Progress IV caught fire in the Black Sea on the evening of 27 August 2026 and subsequently sank in Romania’s exclusive economic zone. All 12 crew members were rescued.
The Romanian Naval Authority received the fire alert at approximately 17:55. The ship was located around 15 nautical miles, or 28 km, from the mouth of the Sfântu Gheorghe branch of the Danube Delta.
Progress IV was sailing under the flag of Dominica. Industry databases identify it as a 122-metre vessel built in 2005, with a deadweight capacity of approximately 7,298 tonnes.
The cause of the fire has not been officially established. Romanian authorities are examining the possibility that the ship was struck, but they have not identified the type or origin of the object involved or attributed responsibility to any party.
After receiving the distress alert, the Maritime Rescue Coordination Centre in Constanța sent the ARSVOM rescue vessels SAR ARES and SAR ARTEMIS to the scene. Romanian Border Police vessel MAI 0201 also joined the operation.
The nearby merchant ship Mohamed B was directed to assist the crew. The first rescue vessels reportedly reached the area approximately 20 minutes after the distress call. Difficult weather and rough seas complicated the response.
Romanian border guards rescued 10 crew members, while Mohamed B recovered the other two. One seafarer was injured. All survivors were brought ashore for medical assessment.
“Ten people were rescued by the border guards, one of them being injured, and two others were rescued by the crew of the merchant ship,” the Romanian Border Police said
Romanian President Nicușor Dan said the vessel appeared to have been struck but stressed that the exact circumstances had not yet been determined.
“The ship was hit and it seems to have sunk, but at present we do not know by whom or by what exactly. There will be an investigation and it will be established, but it is not good for us to start speculating,” Dan said
The president also noted that the incident occurred outside Romania’s territorial waters. Progress IV was in the country’s exclusive economic zone, which gives a coastal state specific rights over natural resources and economic activities but is not part of its territorial sea.
As of 30 August 2026, Romanian authorities had not attributed responsibility to any party. Reports referring to a possible drone strike remain subject to official investigation.
The Progress IV incident occurred amid a growing number of drone-related threats and discoveries in the western Black Sea.
As K2Cargo.News previously reported, Romania destroyed an explosive maritime drone near the Neptun Deep gas project on 20 August. The device was found in the country’s exclusive economic zone, but its origin had not been officially established at the time of publication.
A day before the Progress IV fire, debris from an unidentified drone was discovered on a beach in Romania’s Constanța County. Fragments of other devices were also reported on Bulgarian beaches.
On 27 August, Romanian surveillance systems detected an aerial object approximately 33 km north of Ukraine’s Snake Island. Two Spanish F-18 fighter jets participating in NATO air-policing operations were scrambled to investigate. No connection between that object and the Progress IV incident has been confirmed.
The western Black Sea and the Danube ports are important routes for grain, petroleum products, metals and general cargo. Deteriorating security could affect insurance premiums, freight rates and shipowners’ willingness to send vessels into the region.
Carriers must consider the possibility of diverted or cancelled port calls, higher insurance costs, additional voyage assessments and delays when entering the Danube. Shipowners may also face higher spending on surveillance, risk analysis and crew preparation.
K2Cargo.News earlier covered a new reported strike on a merchant vessel off Odesa. The absence of prompt information about the names, flags and condition of individual vessels continues to complicate efforts to maintain an accurate incident count.
In the Progress IV case, the fire, loss of the vessel and rescue of the entire crew have been confirmed. Whether the sinking resulted from a deliberate attack remains under investigation.
