NATO intelligence has confirmed that Russian sea drones struck and sank the Greek-managed container ship Contship Jet off Bulgaria’s Black Sea coast on October 28, a NATO official told Newsweek, marking one of the most significant confirmed escalations yet in a string of attacks on commercial shipping near the alliance’s eastern flank.
The Liberian-flagged vessel, carrying 421 containers while sailing from Haifa, Israel, to Constanta, Romania, was struck by three naval drones east of Cape Kaliakra in the western Black Sea. All 18 crew members, 14 Filipino and four Ukrainian nationals, evacuated into life rafts and were rescued by Bulgarian naval and border police vessels before the ship sank in Bulgaria’s exclusive economic zone.
Fifth Strike in Bulgarian Waters This Month
The strike on Contship Jet was the fifth drone attack recorded in Bulgaria’s exclusive economic zone in October alone, part of a wider wave of strikes on cargo vessels that also hit the Togo-flagged Alfa Watan and Palau-flagged Able on October 6 near the coastal town of Byala. Other incidents recorded between October 5 and 23 included the bulk carrier HS Dignity and the vessel Khoryv.
Maritime security firm Ambrey said a drone seen on video of the Contship Jet attack resembled a Russian design, though responsibility for the specific strike had not been formally established. Attacks on vessels off Romania and Bulgaria have surged amid escalating fighting between Russia and Ukraine in the Black Sea and Sea of Azov, with ships now facing more than four times as many attacks as six months ago.
Investigation Opens as Defence Ministers Meet
Bulgaria’s Military District Prosecutor’s Office opened a preliminary investigation into the attack the day after it occurred, seeking to establish the circumstances surrounding the strike. The attack took place while defence ministers from Bulgaria, Romania and Turkey were meeting in Sofia to discuss growing security threats across the Black Sea.
A NATO official described the alliance’s commitment to its Black Sea members as ironclad and pointed to plans to invest more than $40 billion in counter-drone capabilities over the next five years. The confirmation of Russian involvement came shortly after Western countries pledged to increase their military footprint in the Black Sea to shield commercial shipping from the fallout of the war.
No Pollution Detected, Hazardous Cargo Noted
Bulgaria’s Black Sea Basin Directorate reported that seawater analyses conducted since the sinking showed no evidence of pollution linked to the incident. Bulgarian outlet maritime.bg had reported that the vessel was carrying containers holding lithium-ion batteries, flammable liquids, gases and other potentially hazardous materials.
The incident adds to mounting concerns over the vulnerability of commercial shipping and critical maritime infrastructure in the Black Sea corridor. The Contship Jet went down in a contiguous zone, an area beyond a country’s territorial waters but fewer than 24 nautical miles from shore.
Why it matters
The confirmed targeting of a Greek-managed merchant vessel by military-grade naval drones underscores the growing risk to commercial shipping transiting NATO member waters in the Black Sea, even as Western governments pledge billions toward counter-drone defenses. For Greek shipowners, who manage one of the world’s largest merchant fleets, the attack highlights the exposure of vessels on established trade routes between the eastern Mediterranean and the Black Sea to military conflict far from traditional high-risk zones. The episode is likely to accelerate insurance and routing reassessments for vessels calling at Bulgarian and Romanian ports, and will add pressure on NATO to move from pledges toward operational measures protecting merchant traffic.
