Black Sea boxship sunk by drones: 20 containers lost as attacks surge
The Liberian-flagged Contship Jet went down 17 nautical miles off Bulgaria after three sea drone strikes
The Greek-managed containership Contship Jet has sunk in the Black Sea after being struck by three sea drones approximately 17 nautical miles east of Cape Kaliakra, Bulgaria. The vessel, en route from Haifa to Constanta with 421 containers, went down around midnight, prompting navigational warnings after at least 20 containers fell overboard.
The Liberian-flagged Contship Jet, operated by Contships Management, was sailing through Bulgaria’s Exclusive Economic Zone (EEZ) when it was targeted by unmanned surface vehicles (USVs). A French naval patrol aircraft detected the drones and alerted Bulgarian authorities, who dispatched naval and border police vessels to the scene. All 18 crew members, 14 Filipinos and four Ukrainians, were safely rescued and taken to Varna.
The vessel sustained three direct impacts before listing and eventually sinking. Bulgarian officials confirmed that at least 20 containers fell overboard during the incident, some of which reportedly contained flammable liquids, gases, and other hazardous materials.
Video footage verified by Reuters showed a sea drone approaching the vessel at high speed before striking its hull.
The attack and its immediate aftermath: Black Sea
Andriy Ryzhenko, a former senior Ukrainian navy officer, stated that the drone in the footage did not resemble any known Ukrainian naval drone model, further complicating attribution efforts.
The sinking of the Contship Jet marks the latest in a series of drone attacks on commercial shipping in the Black Sea this month. Bulgarian Prime Minister Rumen Radev Radev noted that six vessels have been targeted off Bulgaria’s coast, with approximately about two dozen seafarers feared dead. The Khoryv, a merchant vessel, sank near Constanta on October 23 after a similar attack, resulting in one confirmed death and three missing crew members.
Russia has claimed responsibility for two other attacks this week, alleging that the targeted vessels were carrying military or dual-use supplies for Ukrainian forces. However, neither claim has been independently verified, and Moscow has not provided vessel identities.
In response to the escalating threat, NATO members Bulgaria, Romania, and Turkey held security talks, with Turkish Defence Minister Yasar Guler warning both Russia and Ukraine against targeting commercial shipping. The three nations agreed to strengthen maritime intelligence sharing and early-warning arrangements to mitigate further risks.
Regional tensions and broader implications
The recent attacks have raised concerns about the safety of merchant vessels transiting the region, particularly those carrying hazardous or flammable cargo.
For now, the focus remains on search-and-rescue operations and environmental monitoring. Bulgarian authorities are coordinating with neighbouring states to track the lost containers and mitigate potential pollution risks. The incident underscores the growing vulnerability of commercial shipping in conflict zones, where unmanned drones pose an increasingly lethal threat.
Bulgaria is expected to request enhanced NATO surveillance in its EEZ, including additional patrol aircraft and maritime drones. The country’s naval commander, Kiril Mih, has indicated that early-warning systems will be prioritised to prevent further attacks. Meanwhile, the European Union may consider sanctions or diplomatic measures if evidence points to state-sponsored aggression.
For the shipping industry, the sinking of the Contship Jet serves as a stark reminder of the risks in contested waters. Vessel operators are likely to reroute ships away from high-risk areas or demand military escorts, further straining global supply chains. The incident also raises questions about the adequacy of existing maritime security protocols in the face of asymmetric threats like sea drones.
As investigations continue, the Black Sea remains a flashpoint in the broader conflict between Russia and Ukraine. With no clear end in sight, the safety of merchant vessels, and the lives of their crews, hangs in the balance.
