WSJ: Russian oil tankers deploy makeshift drone defenses amid Ukraine attacks

Russian oil tankers are increasingly using protective nets, metal cages and rubber tires to defend against Ukrainian drone attacks targeting Moscow's energy exports, The Wall Street Journal reported.

At least 60 vessels equipped with makeshift anti-drone defenses have been documented passing through Istanbul's Bosporus Strait since August, according to photographs reviewed by the newspaper.

The images, captured by maritime analyst Yoruk Isik, show tankers carrying protective structures around vulnerable areas, including engines, steering equipment, and bridge windows.

Nearly all the vessels identified are subject to U.S. or other Western sanctions for transporting Russian oil.

The defensive measures resemble equipment used on military vehicles and infrastructure in Ukraine, where drones have become a central weapon in the conflict.

Analysts said the nets and cages are intended to intercept incoming drones before they strike critical ship components.

Some vessels have also attached rubber tires along their sides to protect engines and rudders from attacks that could leave tankers disabled.

The modifications reflect growing concerns over Ukraine's campaign against Russia's shadow fleet.

Many aging shadow-fleet tankers rely on insurance and financial backing from Russian state-supported banks, potentially exposing those institutions to losses from damaged vessels.

Ukraine escalated attacks on the fleet in 2025 as Washington pushed Kyiv and Moscow toward negotiations to end the war.

Russian oil shipments remain a major source of foreign currency for Moscow, making the tankers an economically significant target.
