Ukrainian Forces Cripple Russian Shadow Fleet with Overnight Strike, Announcing 20 Vessels Neutralized

Ukrainian Unmanned Systems Forces (USF) have executed a significant overnight assault on Russia’s clandestine “shadow fleet” in the Black Sea, asserting that 20 vessels were struck near the occupied Crimean Peninsula. This latest offensive, part of the ongoing “MoLoChKa” Operation, saw a targeted attack on July 15th that primarily focused on critical maritime logistics assets.

According to USF Commander Robert Brovdi, the drones engaged a fleet comprising 17 oil tankers, 2 gas tankers, and a tugboat. Kyiv alleges these vessels are instrumental in supporting Russia’s military supply chains and energy exports, covertly circumventing international sanctions.

The “MoLoChKa” Operation, which commenced on July 6th with an initial phase in the Sea of Azov, has reportedly inflicted substantial damage on Russia’s maritime transport capabilities. In its first nine days, operations in the Azov Sea alone resulted in 116 purported hits on shadow fleet vessels. The recent Black Sea engagement brings the total number of alleged targets to 136 since the operation’s inception, spanning both strategic waterways.

Earlier attacks, specifically on the night of July 13-14, had already seen the USF claim strikes on 11 vessels, including 5 tankers, 5 dry cargo ships, and a tugboat. Following the intensified Ukrainian activity in the Azov Sea, intelligence suggests a considerable portion of Russia’s maritime assets relocated approximately 50 kilometers westward into the Black Sea. Reports indicate that some damaged vessels have been diverted to repair and storage facilities.

The sustained campaign has had immediate repercussions on maritime traffic. Reuters reported temporary suspensions of vessel movements through the Don-Azov Canal and the critical Kerch Strait, underscoring the operational impact on Russian naval activities.

Ukraine’s strategic objective for the “MoLoChKa” Operation is twofold: to disrupt Russia’s illicit oil and fuel shipments across the Black Sea and Sea of Azov, and to exert pressure on the logistical arteries vital to Crimea. The peninsula serves as a key operational base for Russian air defense, missile systems, combat aircraft, and naval elements.

This current wave of attacks builds upon previous successful Ukrainian engagements using Unmanned Surface Vessels (USVs). Notable past incidents include the Security Service of Ukraine’s (SBU) “Sea Baby” USVs striking the “Kairos” and “Virat” tankers in November 2025, followed by the “Dashan” tanker in December 2025. Most recently, in July 2026, the oil tanker “BLUE” was reportedly hit by a “Sea Baby” off the coast of Yalta, demonstrating Ukraine’s evolving asymmetric naval warfare capabilities.
