**Deck**: Ukraine says it has hit 28 Russian-linked vessels in the Sea of Azov overnight and 76 over six days, including dozens of tankers tied to Moscow’s ‘shadow fleet’ workaround to sanctions. The campaign puts ship crews, insurers and Russian war logistics in the crosshairs — and turns a side sea into a frontline for global energy flows.

Russian-linked tankers and support vessels in the Sea of Azov are increasingly operating as if under siege, after Ukraine’s armed forces claimed overnight drone strikes on 28 ships used to move oil and military cargo, a tally they say brings the total to 76 damaged in less than a week. For Moscow’s war machine, and for the opaque fleet that helps move sanctioned crude, the risk is no longer theoretical.

Ukraine’s military reported in the early hours of 11 July that its forces had attacked 28 vessels in the Azov, including 21 oil tankers, three tugboats, two cargo ships and one special-purpose vessel. A Ukrainian commander of unmanned systems, Robert Magyar, said 26 of those hits were visually confirmed and asserted that 76 ships have been struck in six days. Kyiv frames the targets as part of Russia’s so‑called “shadow fleet” — vessels used to move oil and supplies under sanctions — and as instruments of military logistics. Moscow had not publicly confirmed the scale of the losses by mid-morning, and independent verification of every claimed hit remains limited.

For those who work these waters, the impact is immediate. Tanker and tug crews now face the prospect of long-range explosive drones homing in at night on vessels that once assumed relative safety inside Russia-adjacent seas. Port workers and pilots along the Azov coast are watching a nearby logistics lane turn into a combat zone, with the risk that a miscalculated strike could spill fuel, ignite fires or damage infrastructure close to populated shorelines. Maritime insurers, already charging war premiums for the wider Black Sea, must now reassess the pricing — or insurability — of ships linked to Russian trade inside the Azov basin.

Strategically, the campaign strikes at two Russian vulnerabilities at once: front‑line resupply and sanction‑strained energy exports. The Sea of Azov, linked to the Black Sea via the Kerch Strait, underpins the movement of fuel, grain and heavy equipment to Russian forces in southern Ukraine, as well as some flows of crude and oil products that help Moscow skirt Western sanctions. Disrupting tankers and support vessels does not create a formal blockade, but it introduces enough uncertainty to slow movements, force re‑routing, and test Russia’s ability to protect shipping near its own shores.

Ukraine’s focus on the Azov also extends the geography of the maritime contest beyond better-known battlefields like Odesa and Crimea. Long-range sea drones, refined over more than a year of strikes on the Black Sea Fleet, are now being used against a more dispersed set of smaller, commercially oriented targets. If Kyiv’s claims hold, Russia may be forced to divert scarce air-defense assets, patrol craft and surveillance systems to shield civilian-flagged vessels operating in waters it once considered secure.

The shadow fleet has been one of Moscow’s pressure valves against sanctions, moving oil under flags of convenience, obscure ownership structures and limited insurance disclosure. As Ukraine turns those ships into targets, the quiet calculation changes not only for Russian traders but also for the intermediaries who register, broker and insure them. Shadow fleets work in the gray zone; drone warfare is starting to burn that gray away.

For global markets, the volumes moving through the shallow Azov are small compared to the Black Sea or Gulf chokepoints, but the signal is larger than the tonnage. If sanction-busting tankers can be hunted near Russian ports, the risk discount applied to Russian oil anywhere on the water widens — with potential ripple effects on freight rates, reinsurance and the appetite of third countries to host shadow operations.

The next indicators to watch are whether commercial traffic through the Kerch Strait slows or pauses, whether Russia reinforces naval and air cover in the Azov, and whether Ukraine pushes similar tactics closer to core energy infrastructure. If Moscow begins to escort key tankers or retaliates against what it labels “economic terror,” the contest over how and where Russia can sell its oil will move from regulatory offices to contested sea lanes in full view of global markets.
