The Sea of Azov was supposed to be Russia’s secure, inland sanctuary. After occupying the surrounding coastlines in 2022, Moscow assumed it controlled every wave. That illusion died in July 2026. Over a relentless nine-day campaign, Ukraine launched a brutal, non-contact maritime offensive that crippled Russian shipping, sending panic through Moscow's trade networks.
When Ukraine strikes 116 vessels in the Azov Sea, it does not just hit steel. It cuts the veins of Russian military logistics and hits the Kremlin’s black-market energy exports right where it hurts. The sustained strikes forced Russia to shut down both the Don-Azov Channel and the Kerch Strait. This created a bottleneck that mirrors the Strait of Hormuz.

The Sea of Azov is now effectively closed to commercial traffic. Crimea is sliding into isolation.

How Ukraine strikes 116 vessels in the Azov Sea with cheap drones
You might wonder how a nation without a functional blue-water navy manages to paralyze a heavily armed maritime corridor. The answer lies in asymmetric drone warfare.
The mastermind of this campaign is Robert "Madyar" Brovdi, commander of Ukraine's Unmanned Systems Forces. Dubbed Operation "MoLoCHKa" (a cheeky Ukrainian slang term for a milk run), the offensive utilized cheap, highly coordinated aerial and sea drones. Three distinct Ukrainian drone units—the 1st Separate Center, the 413th Separate Regiment Raid, and the 20th Separate Brigade K-2—hunted down Russian targets night after night.
They did not try to sink the ships. Instead, they did something far smarter.

└── Result: Paralyzed ship becomes bait for rescue tugs
Ukrainian drone operators systematically targeted the bridges and wheelhouses of Russian tankers and cargo ships. If you hit a 140-meter tanker in the hull with a standard drone, you might cause a minor fire or a dent. But if you crash an FPV drone directly through the glass of the ship’s bridge, you instantly destroy the navigation equipment, ruin the controls, and take out the crew.
The ship is not sunk, but it is dead in the water. It becomes a drifting ghost.
This tactic offers massive advantages:
- Zero environmental blowback: By avoiding massive hull breaches, Ukraine prevents ecological disasters that would anger Black Sea neighbors like Turkey or Romania.
- The "Tug Trap": When a tanker is paralyzed, Russia has to send a tugboat to tow it back. Once the tugboat arrives, Ukrainian drones hit the tug.
- Resource drain: Damaged ships require dry docks, spare parts, and months of repair. Russia’s shipyards are already choked with military repairs, meaning these commercial vessels are out of commission indefinitely.
The courier bottleneck of the Russian shadow fleet
To understand why these strikes hurt Russia so badly, you have to understand the geography of Russian oil.
Large, deep-draft ocean tankers cannot enter the shallow ports of the Sea of Azov or navigate the Volga-Don Canal. To bypass this, Russia relies on a "feeder fleet". These are flat-bottomed, medium-sized courier tankers, usually about 140 meters long with a capacity of roughly 7,000 tonnes.
These small couriers pick up crude oil and refined products from Russian river depots and carry them through the Sea of Azov. Once they pass through the Kerch Strait into the deep waters of the Black Sea, they meet massive international tankers. They perform ship-to-ship transfers to load the larger vessels, which then carry the oil to global markets. This is how Russia maintains its shadow fleet and evades Western sanctions.
It is a delicate logistical chain. It takes 12 to 15 runs by these small courier tankers to fill just one large export tanker.
By systematically burning these couriers, Ukraine breaks the chain at the source. Without the small feeders, the big tankers sit empty in the Black Sea. You do not need to hunt down giant ships under foreign flags; you just need to paralyze the domestic workhorses that feed them.
During the peak of the July campaign, Ukrainian forces hit dozens of these feeder tankers, along with dry cargo bulkers and ferry systems. This was "kinetic sanctioning" in its purest form.
Russia is forced into a self-inflicted blockade
The panic in Moscow was immediate. As smoke rose from burning decks across the sea, Russia’s Ministry of Transport made a painful choice: they suspended all shipping through the Don-Azov Channel and closed the Kerch Strait to commercial vessels.
This is the Hormuz-style crisis. By closing its own choke points to protect its ships from drones, Russia created a self-inflicted blockade.
The economic fallout is severe:
- The Grain Squeeze: The Sea of Azov is a prime corridor for agricultural exports. Roughly 25% of Russia’s wheat exports pass through this water. Ports like Rostov-on-Don and the occupied port of Mariupol are now cut off from onward shipping routes.
- Crimean Blackout: Alongside the naval hunt, Ukraine launched a coordinated campaign called "Crimean Switch Off". Drones knocked out nine electrical substations in Crimea and hit the strategic Kuban-Crimea energy bridge.
- The Logistics Nightmare: With sea lanes blocked and railways under constant threat, Russia has to reroute fuel and supplies to Crimea using road transport. Moving fuel in trucks over hundreds of miles of highway is slow, expensive, and incredibly vulnerable to ambush.
Russian Foreign Minister Sergei Lavrov tried to dismiss the attacks, calling them acts of "terrorism" aimed at intimidating civilians. He promised that Russia would fulfill its food supply obligations to African allies. But behind the brave face, Russia’s agricultural ministry is scrambled, desperately looking for alternative land routes to move millions of tons of grain.
Dark screens cannot hide Russia's ships
In a desperate bid to hide their movements, Russian captains turned off their Automatic Identification Systems (AIS)—the transponders that broadcast a ship’s position. Within days of the campaign starting, there was a 55% drop in ships actively broadcasting in the Azov.
It did not work.
The Sea of Azov is a compact, shallow basin. Turning off AIS does not make a 140-meter steel ship invisible. Ukraine utilizes commercial Synthetic Aperture Radar (SAR) satellite imagery. These radar satellites peer through clouds, rain, and darkness, painting a crystal-clear picture of every vessel on the water. If a Russian ship is moving, Ukraine knows exactly where it is.
With the first phase in the Azov Sea wrapping up, Ukraine has already expanded the hunt. On July 15, the Unmanned Systems Forces opened a second front, striking 20 vessels in the Black Sea, including 17 oil tankers and two gas carriers.
For maritime analysts, military strategists, and supply chain observers, the takeaway is clear. Asymmetric drone fleets have fundamentally rewritten the rules of naval blockade. You no longer need a multi-billion-dollar navy to close a sea. You just need a relentless swarm of cheap, smart drones, a clear target, and the will to strike.
