In brief
The container ship CONTSHIP JET sank after three maritime drones struck it east of Cape Kaliakra, 21 nautical miles southeast of Shabla, on Oct. 28, 2026. All 18 crew members were rescued and transported to Varna, and Bulgarian authorities are conducting seawater sampling at multiple locations to monitor for petroleum products, PCBs, and other contaminants. The incident highlights continued drone attacks in the Black Sea and the Bulgarian defense’s efforts to monitor and respond to evolving threats.
A container ship named CONTSHIP JET, carrying 421 containers of fuel and hazardous cargo, sank off Bulgaria’s Black Sea coast after being hit by three maritime drones, according to Varna Regional Administration officials, on Wednesday night.
Varna Regional Administration officials said the vessel was struck 21 nautical miles southeast of Shabla, east of Cape Kaliakra, and sank around midnight. The incident was confirmed by Traffic Control and the Maritime Administration Executive Agency, and all 18 crew members were rescued and brought to Varna. The crew comprised 14 Filipinos and four Ukrainians.
The ship was loaded with lithium‑ion batteries and gas oil, and the 421 containers were destined for a range of destinations. About twenty containers fell overboard during the attack, and the incident added to a growing list of merchant vessel assaults in the area.
Maritime Administration teams inspected the sunken vessel and stated that no significant adverse effects on the marine environment or coastline were expected, because the ship was carrying light fuel oil that evaporates rapidly and is unlikely to reach the Bulgarian coast. The agency noted that the vessels’ condition and the type of cargo made an imminent large‑scale environmental impact unlikely, while acknowledging that monitoring would continue.
Teams from the Defence Ministry had already collected seawater samples from two locations in Bulgarian territorial waters, reporting no visible signs of pollution. The Environment and Water Ministry announced that on Thursday teams from the Black Sea Basin Directorate and the Executive Environment Agency would collect seawater samples at five coastal locations near Durankulak, Shabla, Cape Kaliakra, Byala and Sozopol.
The collected samples will be tested for petroleum products, polychlorinated biphenyls, metals and other physicochemical indicators of water quality. They will be analysed at the Executive Environment Agency’s regional laboratories in Varna and Burgas, as well as in laboratories near the area of the ship’s sinking. The Environment Ministry said that results will be released to the public.
Environmental Monitoring Plan
Admiral Emil Eftimov, Bulgaria’s outgoing Chief of Defence, said in an interview for bTV that the drones that struck the container ship came from the east and did not enter Bulgarian territorial waters. He highlighted increased efforts in intelligence, surveillance and early‑warning systems, and noted that new anti‑drone capabilities are being deployed. He stated that, because the threat originated from the east, Bulgaria remains on alert while preserving its defensive posture.
Eftimov also explained that the situation in the Black Sea has expanded, with attacks not only near the conflict zones but also around Bulgaria’s waters, and that the country’s armed forces are adapting their strategy and procurement to maintain an effective response.
Officials in the defence, maritime and environmental ministries are coordinating their efforts to monitor the situation and to respond if any pollution risk or change in the Marine environment is detected. While the drones did not enter territorial waters, the incident underscores the increasing frequency of maritime drone attacks in the Black Sea, prompting authorities to intensify surveillance and sampling in the affected regions.
