Ukraine's Operation Molochka strikes 13 more Russian shadow fleet vessels on July 18, bringing total to 172 ships in 13 days

Summary

Ukraine's Unmanned Systems Forces struck 13 more vessels from Russia's shadow fleet on July 18, targeting ships in the Black Sea and Azov Sea as part of the named Operation Molochka, raising the campaign's 13-day total to 172 ships. A separate strike hit the Slavneft-Yanos oil refinery in Russia's Yaroslavl Oblast on the same night, the latest in what Ukraine frames as a campaign to sever Crimea from mainland Russian supply lines. The July 18 strikes follow the July 17 wave in which 12 vessels were hit, the largest single-day operation at that point, and continue a persistent drone campaign using unmanned maritime and aerial systems from Ukraine's Unmanned Systems Forces.

The split

Ukrainian official outlets (United24, Kyiv Post) foregrounded the campaign's scale and named the operation, presenting 172 ships in 13 days as evidence of strategic effect on Russia's sanctions-evasion economy. APA (Azerbaijan) carried the news neutrally as a regional transit-security story, noting Ukraine's framing without endorsing it. Eastern Herald was alone in linking the shadow fleet campaign to a mainland refinery strike, suggesting a broader campaign logic that Ukraine's official communications kept separate. Western outlets largely treated the cumulative number as a data point rather than exploring how the shadow fleet's degradation affects Russian oil revenue or European insurance exposure.

By the numbers

• 13, vessels struck by Ukrainian drones on July 18
• 172, total ships targeted in Operation Molochka in 13 days
• 2, bodies of water with simultaneous strikes: Black Sea and Azov Sea
• 12, vessels struck the preceding day (July 17), the previous single-day record

Why it matters

The shadow fleet is Russia's main channel for exporting oil above the G7 price cap. Sustained attrition at 13 vessels a day puts pressure on the shipping operators and insurers who provide cover to the fleet; even vessels that survive drone strikes face the prospect of uninsurability. The Azov Sea strikes are strategically distinct, targeting the supply corridor Russia uses to move materiel into occupied southern Ukraine, not just the oil-export apparatus.

What to watch

• Whether Russia deploys armed escorts or anti-drone systems to protect the remaining shadow fleet vessels
• Whether the cumulative losses force a detectable reduction in Russian oil-export volume through the Bosphorus corridor
• Whether Ukraine names specific ship owners or flags as part of an accountability or pressure campaign
• How wheat-carrying vessels are affected as the drone campaign widens to the Azov
