Russia's Shadow Fleet Tankers Add Anti-Drone Protection in Black Sea
Russian oil tankers from the sanctions-evading “shadow fleet” have begun fitting nets, metal structures and rubber tires to protect themselves from Ukrainian drone attacks. Since August, at least 60 protected tankers have passed through the Bosphorus as the fleet adjusts to growing threats to Russian maritime oil exports.
Key points
- Russian “shadow fleet” tankers are fitting nets, metal structures and tires for protection against Ukrainian drones
- At least 60 tankers equipped with anti-drone protection have passed through the Bosphorus since August
- Shadow-fleet tankers have been passing through the Bosphorus almost daily since August
- Most photographed tankers are under US and other Western sanctions for transporting Russian oil
- Rubber tires are suspended near engines and steering gear to impede drones
- The British government sanctioned eight vessels Russia planned to use for a new LNG shadow fleet
- Attacks on tankers form part of a broader Ukrainian campaign targeting Russian oil revenues
Why it matters
The modifications indicate that Ukrainian drone strikes pose a growing threat to Russian maritime oil exports and a major source of Kremlin revenue. At least 60 protected tankers have passed through the Bosphorus since August, showing the scale of the shadow fleet's response. The measures also expand protection against surface drones and medium- and long-range airborne FPV drones.
What happened
Russian oil tankers operating in the sanctions-evading “shadow fleet” have started equipping their decks with nets, metal protective structures and rubber tires. Analysts believe the installations are being completed hastily to shield vulnerable areas, particularly engines and steering gear. The measures also reflect the fleet's growing need to protect against both surface-moving maritime drones and medium- and long-range airborne FPV drones.
How Ukrainian sources describe it
Ukrainian reporting presents the attacks on tankers as part of a broader campaign of economic pressure on Russia that also includes strikes on oil refineries and data-processing centers. Ukrainian sources also emphasize the continued daily passage of shadow-fleet vessels through the Bosphorus and the extent of the protective modifications already installed.
How international sources describe it
International coverage emphasizes that most photographed tankers are under Western sanctions and that Russia's foreign-currency oil income is increasingly exposed to attack. Maritime observers and analysts interpret the new defenses as evidence of broader danger to Russian shipping in the Black Sea. Nets and cages are inexpensive and simple, prompting forecasts that similar protection could become a widespread global measure.
Background
Ukraine previously reported attacks on Russian tankers using maritime drones that travel on the water's surface. Similar metal structures have already been used to protect Russian and Ukrainian military equipment and Israeli forces against FPV drones. The shadow fleet largely operates outside international marine-insurance and shipping rules and often relies on Russian state-controlled banks for insurance and financial backing.
