Ukraine has announced that its naval drone units successfully struck two large Russian oil tankers, named Kairos and Virat, which were reportedly operating as part of Russia’s “shadow fleet” used to move oil outside regular sanctions-compliant channels. The attack took place in the Black Sea near the route leading to the Novorossiysk oil terminal.
According to Ukrainian security officials, both tankers were hit while travelling without cargo. Dramatic footage and eyewitness accounts describe explosions and fires on board, with the Kairos suffering extensive damage and catching fire soon after the drone impact. Its 25-member crew was evacuated to safety, with no casualties reported. The Virat was also damaged, though it did not ignite, and its crew too is said to be safe.
Ukraine’s government says the attack was part of a wider strategy to disrupt Russia’s energy export network, especially the vessels used to bypass sanctions and covertly transport oil. By targeting the shadow-fleet infrastructure, Kyiv aims to erode Russian oil-export revenue which plays a significant role in sustaining its war operations.
Analysts note that Ukraine has increasingly expanded its military strategy beyond land engagements, focusing on maritime operations using remote and precision-guided naval drones. The strike underscores Ukraine’s capacity to hit Russian economic assets far from the traditional conflict line.
While the incident adds fresh pressure on Russia’s energy-transport logistics, it also heightens regional security concerns, particularly regarding civilian shipping safety and international oil flow through the Black Sea corridor. Naval monitoring agencies and maritime authorities are expected to issue updated guidance for vessels navigating these waters in the coming days.
