Ukrainian forces struck three Russian oil-transport vessels in the Black Sea on Sunday [1], [2].

These attacks target the "shadow fleet" of tankers that Russia uses to bypass international sanctions. By disrupting this infrastructure, Ukraine aims to reduce the revenue available to fund Russia's military operations.

The strikes occurred near the Russian port of Novorossiysk [3], [4]. Ukrainian military drones targeted the vessels as part of a broader campaign to pressure Russia's energy export capabilities. The operations focus on the logistics of oil loading and transport to weaken the economic stability of the Russian war effort [1], [3].

President Volodymyr Zelensky said Ukrainian forces struck shadow fleet tankers in waters at the entrance to the port of Novorossiysk [4]. While some reports indicated two vessels were hit, other sources confirmed three tankers were targeted in the operation [1], [2].

The maritime strikes coincided with wider conflict activity across both nations. Reports indicate that eight people died in both countries on the day of the strikes [1].

Ukraine has increasingly utilized long-range drones to hit energy infrastructure deep within Russian territory. These targets include refineries and loading ports, critical nodes in the Russian economy that allow the state to export crude oil to global markets despite Western restrictions [1], [3].

The targeting of the shadow fleet represents a strategic shift toward economic warfare. By attacking the specific vessels used to evade sanctions, Ukraine is attempting to create a physical bottleneck in Russia's oil export chain, potentially increasing the cost of insurance and shipping for Russian crude.
