Ukrainian Drones Strike Russian Shadow Fleet Tankers in Sea of Azov

The Ukrainian Armed Forces are escalating their operations against Russian energy infrastructure, triggering widespread fuel shortages across Russia and imposing an energy and logistics blockade on the Russian-occupied Crimean Peninsula. Recent attacks have targeted Moscow's "shadow fleet" tankers in the Sea of Azov and the port of Kerch.

Operation "MoLoChKa" Targets Russian Shadow Fleet

The Ukrainian Unmanned Systems Forces (USF) report having attacked a total of 116 Russian vessels between July 6 and July 14, 2026, as part of Operation "MoLoChKa" [Dairy Industry], which commenced on July 6.

In a statement on their X social media account, the USF detailed their latest strikes in the early hours of July 14, during which unmanned aerial vehicles (UAVs) hit five tankers, five cargo ships, and one tugboat in the Sea of Azov. The USF explained the broader objective of the operation:

"Despite international sanctions, Russia continues to export oil via its shadow fleet, thereby funding its war against Ukraine. The goal of the operation is the systematic disruption of the enemy's logistics chain. Disabling tankers, cargo ships, and auxiliary vessels complicates the export of oil and petroleum products, limits maritime transport capacity, and reduces the enemy's ability to supply fuel to its forces and the occupation group on the temporarily occupied Crimea. In this way, the operators of the unmanned systems forces weaken one of the key elements of Russian military logistics and one of the sources of funding for its aggression."

Focus on Feeder Tankers

In a Telegram post on July 14, USF Commander Major Robert 'Madyar' Brovdi explained that Operation "MoLoChKa" specifically targets Russia's smaller feeder tankers.

"Paralyzing the Russian feeder fleet (small and medium-sized shallow-draft shuttle tankers, 140 meters long with a carrying capacity of 7,000 tons each), which constitutes a significant component of the Russian shadow fleet, makes it practically impossible to export 'black gold' from Russian oil transshipment bases and loading terminals in ports via the Volga-Don Canal and the Sea of Azov onto large tankers," Major Brovdi stated.

He elaborated on the logistical vulnerability:

"These large tankers, due to their draft, cannot enter oil terminals or ports and are therefore forced to be loaded in the Black Sea from the tanks of these shuttle tankers, taking on cargo from 12 to 15 such vessels traveling along the water surface."

Major Brovdi further noted that destroying these vessels—along with the tugboats that tow them after being hit—disrupts fuel deliveries to Crimea through the shallow waters of the Sea of Azov. This forces Russia to rely on road and rail tankers as the primary delivery method, which he described as "highly dangerous" and also vulnerable to Ukrainian combat drones.

Size of Russia's Shadow Fleet

Accurately determining the size of Russia's global shadow fleet remains difficult, as the country employs shell companies, hidden ownership networks, and frequent flag changes to conceal its operations. However, shipping and defense experts estimate that between 1,000 and 1,600 vessels are involved.
