Drone Strikes Sink Merchant Ship in Bulgaria Black Sea Zone as Maritime Attacks Expand Westward

BLUFAnother commercial vessel is likely to be struck in Bulgarian or Romanian waters by the end of October, forcing NATO-member insurers and shipowners to reprice western Black Sea routes before any attacker is formally identified.

Drones struck two merchant ships in Bulgaria's exclusive economic zone about 70 nautical miles east of Byala at around 3am on October 6, according to Prime Minister Rumen Radev, as reported by EU Today 1. The Togo-flagged ALFA WATAN sank with its crew's fate unknown, while all 18 aboard the Palau-flagged ABLE were rescued after it caught fire 1. Bulgaria has made no formal attribution, and a rescued Turkish sailor's claim of a Russian underwater drone is unverified 1. A day earlier, the Turkish-owned Royad Mammadov, carrying corn from Izmail, was hit in Romania's economic zone about 9 nautical miles southeast of the Pescarus platform 23. Romania's Interior Ministry reported two dead and 11 rescued 2, and Zelensky blamed two Russian drones, which Romanian authorities did not themselves confirm 12.

Analysis
Another commercial vessel is likely to be struck by a drone or similar weapon in Bulgaria's or Romania's exclusive economic zone between October 9 and October 31. Confidence is low: nearly all sourcing traces to one Kyiv Independent and EU Today cluster, no official attribution exists, and Bulgarian and Romanian accounts of the weapons remain unreconciled. Two hits on consecutive days, the second 70 nautical miles offshore, suggest the targeting area has moved beyond waters near Ukrainian ports. Stray munitions or a damaged ship drifting across zones could instead explain the pattern, as Mediafax reported one drifting toward Bulgarian waters. If another strike occurs, authorities and war-risk underwriters would move to convoy, escort or suspend western Black Sea transits. If none occurs, current routing and premiums can stand.
