317 Ships Hit in Six Months as Black Sea War Edges Into NATO Waters

Ships sailing in or near NATO waters absorbed seven strikes in October alone, and 317 merchant and other vessels were hit across the Black Sea and Sea of Azov between May and October — a more than fourfold jump from the 74 vessels attacked in the previous half-year. The escalation has throttled a trade lane that carried millions of tons of grain and oil, pushed attacks inside Romania's and Bulgaria's exclusive economic zones, and left NATO's eastern flank scrambling for a response.

Three days after NATO announced it would deploy maritime patrol aircraft, radars and drones to reinforce its Black Sea members, another ship was struck on October 23 just outside Romanian waters. Last week, a Greek container ship sank after naval drone hits in Bulgaria's exclusive economic zone.

Who is behind the strikes?

Military analysts said they had little doubt these were Russian attacks. Shipping security firm Ambrey noted that a naval drone visible in video of the most recent strike resembled a Russian variant. Russia denies targeting Ukraine's neighbors and accuses European governments of escalating the war by supplying military aid; its defense ministry did not respond to a request for comment.

"I think it's undeniably an escalation," said Sidharth Kaushal, a senior fellow at the London-based RUSI think-tank.

Many of the ships hit in October were anchored near, or sailing to and from, a key Romanian canal Ukraine uses for exports. One attack occurred in Romanian territorial waters; the other eight struck vessels in Romania's or Bulgaria's exclusive economic zones.

What does the escalation mean for NATO?

Iulia Joja, director of the Black Sea program at the Washington-based Middle East Institute, argued Russia is calibrating its attacks to Western reluctance to escalate. "This is about testing these red lines, with full awareness that we will do everything possible to take the most minimal measures," she said, comparing the strikes to Russian drone incursions into NATO airspace in recent years.

A NATO official called Russian actions aimed at dissuading allies from supporting Ukraine a serious security threat, and described the alliance's commitment to defending all members, including Black Sea littoral states, as "ironclad." The official pointed to a clear need for cost-effective counter-drone capabilities, saying NATO has already committed more than $40 billion to counter-drone investment over the next five years — roughly $8 billion per year.

The geography raises the stakes. For Romania, the Black Sea is a crucial trade waterway and home to its offshore Neptun Deep gas project, which will make it the EU's largest gas producer next year; a naval drone approached the platform in August. Bucharest has accused Russia of "systematic" strikes on civilian ships but stopped short of attributing individual attacks, citing the need for forensic evidence. Sofia has not blamed Russia directly, but said some of the attacks appear to benefit Moscow.

Timing compounds the problem. Washington, focused on China, is reassessing its military presence in Europe and withdrew 1,000 troops from Romania last year. "It's a moment in the transatlantic relationship that Putin likely wants to use," a senior Romanian official said. "The EU and NATO's attention is important and their forces are currently focusing towards the north and the Baltics."

While NATO has reinforced its enhanced forward presence in the Baltics and Poland, Joja noted, it has not done the same in Romania despite Bucharest's requests. "Brussels and Washington still don't seem to have decided whether the Black Sea is fully part of the NATO commitment," she said. The Romanian official flagged an urgent need for surface-to-air interceptors and radar systems, and Joja added that limited stocks of cheap interceptors — worsened by the war in Iran — remain a central problem for the West.

How hard has shipping been hit?

The numbers are stark on both sides of the war. Ukraine carried out 137 attacks on ships versus 92 Russian strikes in the third quarter, according to Ambrey data; in October, Russia hit 38 vessels against 5 Ukrainian strikes. The tempo has fluctuated ahead of the fifth anniversary of Russia's full-scale invasion in February.

Export volumes tell the commercial story. Russia moved just 0.3 million metric tons of grain through the Black Sea and Sea of Azov in September, down from 4.74 million tons in the same month last year — a drop of about 94% — according to Russian export data seen by Reuters. Ukraine suspended operations at its Black Sea ports in late July after Russian attacks and diverted volumes to Danube river ports, through Romania's Sulina Canal and south along Romania's Black Sea coast. Even so, Ukraine's port grain exports fell to 0.81 million tons in September from 2.1 million tons a year earlier.

Andriy Ryzhenko, a naval analyst and former senior Ukrainian naval officer, said shrinking these volumes further remains Russia's primary goal, with testing NATO a secondary objective.

Is a maritime ceasefire in sight?

Last week's attack coincided with a Sofia meeting of defense ministers and military chiefs from Romania, Bulgaria and Turkey. Turkey, awaiting responses from Moscow and Kyiv on a narrow maritime ceasefire proposal, used the meeting to warn both sides against further attacks. Ankara controls warship transit through the Bosphorus and Dardanelles under the Montreux Convention.

Several countries, including Egypt, Turkey and India, have pushed for maritime ceasefires to limit fallout at a time of soaring global fuel and grain prices. US Secretary of State Marco Rubio said on Saturday that international interest in a limited ceasefire is growing. Russia has rejected a narrow maritime truce it says would give Kyiv respite.

Ukrainian President Volodymyr Zelenskiy warned of the consequences last month: "Everyone is talking about diesel and forgetting about grain. In a month or two, everyone will start talking about an agricultural crisis." With strike volumes running at four times their prior pace and NATO's counter-drone investment still years from full deployment, shippers routing grain and energy cargo through Romanian waters face a worsening risk calculus heading into winter.
