Ukraine’s spy service and navy team up to strike two Russian crude tankers in the Black Sea

Ukraine's Security Service (SBU) struck two sanctioned Russian oil tankers with naval drones in the Black Sea, the SBU said. The vessels belong to the shadow fleet Moscow uses to sell crude around Western sanctions, and Russian aircraft tried and failed to stop the attack.
Two tankers, one sanctions-busting job
The SBU, working with the Navy, hit the ocean-going tankers Louise 1 and Banda — both under Ukrainian sanctions — with Mamai naval drones.

Louise 1 had moved Russian crude through the G7 and EU embargo, loading at Baltic and Black Sea ports with its transponder switched off. In 2026 alone, it carried nearly 3 million tons of Russian Urals crude, the SBU said.

Banda had run Russian crude out of four ports: Ust-Luga, Kerch, Novorossiysk, and Nakhodka.

As the drones closed in, Russian aircraft fired machine guns and dropped bombs at them, without success, the SBU said.
The service calls each shadow-fleet tanker a legitimate target and a working part of Russia's war machine. Every strike, it says, cuts the oil money paying for the invasion.
A week earlier, the SBU's Sea Baby drone hit the sanctioned tanker Blue in Ukraine's waters off occupied Yalta. Ukraine has spent 2026 turning cheap drones into kinetic sanctions on Russia's tanker fleet. Sea Baby drones have wrecked shadow-fleet tankers across the Black Sea since late 2025.
The air campaign running alongside it
The naval strikes run in parallel with an aerial-drone campaign by the Unmanned Systems Forces (SBS). On 16 July, SBS operators struck 11 more shadow-fleet vessels — five oil tankers, a gas carrier, three dry-cargo ships, and two tugs.

That brought the 6–16 July total to 147 vessels: 117 in the Sea of Azov and 30 in the Black Sea.
"The goal: paralysis of the logistics of oil, fuel, and cargo that bypasses sanctions," commander Robert "Madyar" Brovdi wrote.
