Ukraine’s drone campaign against Russia’s sanctioned oil tankers just hit a new gear. Three crude-oil tankers were struck by drones off Turkey’s Black Sea coast overnight, marking the most aggressive single wave of attacks yet against vessels ferrying Russian crude in defiance of international sanctions.
The strikes are the latest chapter in what Ukrainian officials have described as “kinetic sanctions,” a strategy that uses unmanned maritime drones to do what traditional economic penalties have struggled to accomplish: actually stop Russian oil from reaching global markets.
A pattern of escalation
On March 26, 2026, a Ukrainian maritime drone struck the Altura, a Sierra Leone-flagged tanker operated by a Turkish company, roughly 15 to 24 kilometers from the Bosphorus Strait. The vessel was carrying approximately 140,000 tons of crude oil loaded at Russia’s Novorossiysk port. The explosion damaged the engine room and deck, though all 27 crew members escaped unharmed.
The Altura had been sanctioned by the EU, UK, Ukraine, and Switzerland, making it a textbook member of Russia’s so-called shadow fleet. These are the aging, often poorly maintained tankers that shuttle Russian crude under murky ownership structures, skirting the price caps and trade restrictions imposed after the 2022 invasion of Ukraine.
