How Kyiv is using a relentless aerial campaign to paralyze Russia’s inland waterways, disrupt global grain markets, and rewrite the rules of naval warfare.

116 attacks in nine days, and counting. Operating without a traditional air force or naval surface fleet, Ukraine’s Unmanned Systems Forces (SBS) have unleashed a highly coordinated, high-tempo aerial drone campaign over the Sea of Azov, now entering its second week of attacks. What began as a localized effort to restore Ukrainian control over the Sea of Azov on July 6 has now expanded into a systemic, theater-wide drone offensive on Russian commercial shipping in the northwest quadrant of the Black Sea.
To mark Ukrainian Statehood Day on July 15, 2026, the Unmanned Systems Forces (USF) announced it has aggressively widened its maritime drone offensive beyond the Sea of Azov, striking an additional 20 Russian vessels overnight in the Black Sea. According to USF Commander Robert “Madyar” Brovdi, the targets—hit under the banner of the rapidly expanding Operation MoLoChKa—included 17 oil tankers, 2 gas tankers, and 1 tugboat. Brovdi’s choice of the name “MoLoChKa” (the Ukrainian/Russian slang for dairy) directly mocks the Kremlin’s recent, desperate logistics crisis on the nearby R-280 highway.
After relentless Ukrainian drone strikes paralyzed the overland “highway of death,” Russian forces were caught disguising their military fuel tankers as civilian food and milk transport trucks. By naming the maritime blitz “Operation Milk Run,” Brovdi is implying that in addition to its land routes, Russia’s critical sea routes are now exposed to Ukrainian drone attacks. By striking 11 more vessels in the Sea of Azov alongside the massive Black Sea blitz, Ukraine’s ten-day tally has reached a staggering 116 ships hit as of this writing, July 15.
At the same time, Kyiv is targeting a critical Russian geographic vulnerability because Moscow’s massive, deep-draft tankers cannot enter the shallow Azov Sea. Moscow relies on a highly specialized logistical chain involving smaller feeder vessels transporting grain and oil from inland river ports through the Volga-Don canal. These ships navigate the Azov Sea to transfer their cargo to larger vessels at offshore transshipment points in the Black Sea outside the Kerch Strait.
By systematically hunting down both the feeder fleet and the deep-draft receivers, Kyiv is not just challenging the Kremlin’s claim that the Sea of Azov is an uncontested Russian “internal sea”—it is physically bottling up the Volga-Don shipping canal, triggering a cascading logistical and financial paralysis that is sending shockwaves from domestic insurance markets to global agricultural desks.
Backlash on the Russian Maritime Insurance Market
If Ukrainian drone strikes were not enough, Russian concerns were amplified due to skyrocketing maritime insurance rates. The Russian newspaper Kommersant is reporting that Russian insurance companies are now refusing to provide insurance for Russian vessels operating in the Azov Sea. The physical destruction wrought by Operation “MoLoChKa” has triggered an unprecedented financial crisis within Russia’s domestic underwriting market. Citing the Central Bank of the Russian Federation, Kommersant reported that domestic reinsurance losses for terrorism, sabotage, and drone risks skyrocketed by an astronomical 2,800% in the first four months of 2026. Faced with paying out 28 times more in claims than they collect in premiums, Russian insurers initially doubled or quadrupled cargo tariffs. However, as the daily strikes have mounted in the past week, major underwriters have begun outright refusing to cover “war risks” in the Black Sea and Sea of Azov basin.
This underwriters’ strike will likely deal a paralyzing blow to Russian maritime logistics. Without indemnity guarantees, commercial operators will not risk transporting high-value cargo—such as oil and gas consignments where cargo values routinely exceed $150 million. While the Kremlin struggles to broker a solution, debating whether to force private businesses to pool a joint insurance fund or demand state subsidies the federal budget cannot afford, Russia’s critical maritime arteries remain financially uninsurable.
A New Tanker War in the Black Sea
The sheer scale of Ukrainian drone strikes is fundamentally altering the security architecture of the far northeastern section of the Black Sea, making Russian commercial and military activity in the Sea of Azov non-operational. Late last year I wrote about an onslaught of attacks by Ukrainian USVs on the Russian shadow fleet operating in the Black Sea. These attacks are rapidly being eclipsed by the level of intensity of Ukrainian UAVs in the Sea of Azov at an unprecedented level.
Today, the Financial Times newspaper reported that the number of Russian ships hit by Ukrainian drones in the current timeframe has exceeded the number of strikes between Iraq and Iran during the Persian Gulf tanker war of the 1980s, when there were 450 attacks in the span of seven years.
Ukrainian drone attacks on Russian shipping are exacerbating Russian logistical efforts to supply its forces in occupied Crimea. For the past month, Russian forces in Zaporozhia have been reeling from Ukrainian attacks on the highly strategic R-280 highway used as a land bridge from occupied Crimea to supply Russian forces operating in a zone they refer to as “Novorossiya.” Ukraine has relentlessly attacked the Russian “MoLoChKa” oil tankers using the route as well as systematically destroying the bridges from Crimea used by Moscow in an effort to restrict Russian movement through the strategic corridor.
After weeks of punishing attacks on the R-280, Ukraine suddenly shifted its strategic attention to the Sea of Azov – strangely enough, following the recent NATO summit meeting in Turkiye. By systematically hunting down Russia’s maritime assets, Ukrainian Uncrewed Aerial Vehicles (UAVs) have inflicted staggering losses on Moscow’s commercial and logistical fleets using the Inland Azov Sea as part of its internal supply lines to beleaguered forces in Crimea. Within a
matter of more than a week, the Azov campaign has targeted everything from shadow fleet oil tankers and dry cargo ships to tugboats, ferries, and dredgers.
The compounding tactical successes by Ukraine have forced an unprecedented logistical paralysis on the Kremlin, forcing the Russian Federal Security Service (FSB) Border Service to officially announce a suspension in civilian commercial navigation through the Kerch Strait and the Don-Azov Shipping Channel earlier this week. More importantly, Ukraine’s sudden chokehold on the Sea of Azov is now threatening Russia’s highly strategic Volga-Don Canal, as Ukraine threatens to sever a critical Russian economic and military artery, which could end up triggering immediate volatility in global agricultural markets and trapping Russian internal maritime logistics in a cascading backlog in Russia’s Volga-river network.
The Volga-Don Canal and the Russian Heartland
To understand the profound strategic weight of the Azov campaign, one must look at the complex domestic geography that underpins Russia’s inland waterways and logistical network. The strategic connection between Taganrog, the Volga-Don Canal, and Russia’s ability to manage a Sea of Azov shutdown reveals the complex logistics involved in the global agricultural trade and how this waterway interacts with the rest of Russia.
Russian foreign policy has long been driven by a desire for defensible borders and strategic depth, and this doctrine is especially relevant in the context of Putin’s ongoing war against Ukraine. The Volgograd Gap, touted by Ukraine analyst Bogdan Maftei, is a critical geographic corridor between the Black and Caspian Seas that has been a focal point of Russian defensive strategies that have existed for centuries, making it a major security concern and highly relevant in the context of the ongoing Ukraine war and Ukrainian aims driving its military strategy in its drone blitz in the Sea of Azov.
Russia’s Integrated Deep-Water System
One of the particular targets in Ukraine’s drone campaign in the Sea of Azov is the targeting of the port of Taganrog. Situated at the eastern end of the Inland Sea, Taganrog acts as the maritime gatekeeper and receiving terminal for the Volga river’s egress to the Sea of Azov, and the Black Sea. Known as the Integrated Deep-Water System of Russia, the Volga’s internal waterway system operates as both a commercial and military highway that reaches as far as the Baltic and is part of a vast network of domestic rivers and canals that unite the Caspian Sea, the Baltic Sea, and the Russian heartland directly to the Sea of Azov and the Black Sea. Within this network, the Volga-Don Canal serves as the critical 64-kilometer (40-mile) link connecting the Volga River to the Don River.
As a part of this internal river network, agricultural bulk cargo and grain are loaded onto specialized “river-sea” coaster vessels and barges deep within the Russian interior, such as the Samara, Saratov, or Volgograd regions. These ships travel down the Volga, pass through the locks of the Volga-Don Canal, enter the Don River, and empty into the Gulf of Taganrog.
The Strategic Importance of Taganrog
Once the Russian river fleet arrives in the Gulf of Taganrog, the city’s port functions as a vital transshipment hub. Operating as a key terminal within the Sea of Azov basin, Taganrog port is structurally vital to Russian agricultural logistics. While the deeper Black Sea port of Novorossiysk handles Russia’s largest bulk volumes, the shallow-water Azov basin ports—including Taganrog, Rostov, and Azov—collectively account for 25% (one-quarter) of Russia’s total global wheat and grain exports. Consequently, Taganrog serves as a critical river-sea transit hub for Russian crops harvested in its agricultural heartlands of Rostov and the Volga region. Its disruption directly bottlenecks the flow of millions of tons of Russian grain destined for Western and Mediterranean markets, particularly Africa.
Taganrog’s specialized passing channels and anchorages allow shallow-draft river vessels to safely enter the harsher Sea of Azov maritime environment. From this point, they either head directly to Mediterranean markets or transfer their loads to massive ocean-going bulk carriers waiting in deeper waters. By striking the mouth of this system, Ukraine has effectively corked the bottle of Russia’s internal river to the sea shipping network that makes up the Volga-river system. By the way, lest we forget the Volga happens to be the longest river in Europe, stretching about 3,530 kilometers (2,193 miles).
Long-range Ukrainian drone strikes on the port of Taganrog have amplified Russia’s paralysis as Kyiv also struck the city of Azov, igniting a catastrophic fire at the Kurgannefteprodukt port terminal. This terminal is highly specialized, transferring petroleum products directly from rail lines onto marine hulls. Satellite data from the Planet network and the Sky Eye monitoring project captured a massive 3-kilometer oil slick spreading south from the Taganrog coastline into the bay. Rostov Oblast Governor Yuri Slyusar acknowledged that the specialized port fires could not be put out quickly, forcing local emergency regimes and evacuations. Even as Russia attempted to tow damaged, smoking tankers into the occupied port of Kerch, subsequent drone waves struck vessels entering the canal mouth, rendering the entire waterway unusable.
Anatomy of Ukraine’s Maritime Blitz in the Azov Sea: July 9 to 12
The sheer scale of the Ukrainian drone offensive appears to have caught Russian officials completely off-guard. Port authorities and naval defenses had to resort in recent days to shutting down, most if not all, activity in the Sea of Azov to reassess the direness of the situation. The drone operation represents a massive, calculated effort coordinated by the SBS Deep Strike Center, which has been operational since December 2025.
Detailed chronologies provided by SBS Commander Robert “Madyar” Brovdi illustrate an exponential escalation night by night:
- July 6: The campaign opened with joint operations between the SBS and the Ukrainian Navy striking two “shadow fleet” tankers, the Kapitan Barmin and the Sanar-4 (a Project 15781 river-sea vessel), each carrying roughly 7,000 tons of gasoline bound for Crimea. Drones specifically targeted the control rooms of the vessels.
- July 7: The operation widened significantly, hitting ten additional tankers, a dry cargo ship, and the ferry SKS One.
- July 8: Nine more tankers were successfully targeted in the Sea of Azov near the Kerch Strait.
- July 9: Drone crews struck another 14 shadow fleet vessels overnight, including 12 tankers, a cargo ship, and the tug Alfeo towing the barge Aphrodite. Highly sanctioned vessels, such as the Panama-flagged Galiaskar Kamal, were among those hit. Several ships, such as the Sanar-17 and Klimena, were struck multiple times across successive nights.
- July 10–12: The onslaught culminated in massive back-to-back strikes. On the night of July 12 alone, drones struck 10 tankers and four ferries.
Breaking these attacks down further according to one estimate, between July 6 and July 12, Ukrainian drone units struck 90 Russian vessels—averaging one tanker, tugboat, ferry, or cargo ship every 112 minutes. Given that military analysts estimate the total number of active Russian vessels operating in the Sea of Azov sector to be around 120, Ukraine successfully targeted approximately 75% of the entire regional fleet in a single week.
The immediate tactical effect has been a mass exodus and depletion of active Russian commercial ships operating in the Sea of Azov. Satellite records and maritime tracking via the Telegram channel Oko Gora revealed that the number of tankers stationed near Kerch has plummeted by 75%, dropping from 37 vessels down to just 9. Most surviving ships fled approximately 50 kilometers out into the safety of the Black Sea proper, while others withdrew into repairs or dry storage.
Conclusion: A Masterclass in Asymmetric Maritime Warfare
The multi-layered drone campaign executed by Ukraine’s Unmanned Systems Forces represents a major turning point in the war in the Black Sea, if not for the entire war. Ukraine’s asymmetric strategy has expanded from enforcing its logistical lockdown of the R280 highway to targeting the Sea of Azov, and now a full-fledged tanker war threatens to engulf the eastern coast of Crimea and the approaches to the Kerch Strait. Since Moscow has halted fuel and ammunition shipments on the Kerch Strait Bridge following the devastating 2022 Ukrainian attack, Russia’s backup maritime arteries to Crimea are now in serious jeopardy and are creating a momentous operational challenge for the Russian leadership to rectify.
By deploying low-cost, long-range strike drones in rapid, relentless waves, Ukraine has successfully neutralized a massive commercial fleet, crippled regional port infrastructure, and forced the total suspension of traffic through the critical Volga-Don maritime pipeline. Without using a single major surface warship, Ukraine has fundamentally rewritten naval rules of warfare by using air power – in this case, its fleet of unmanned drones – to eliminate Russian sea control in the Azov Sea, effectively creating what in naval terms is referred to as Sea-Denial without even necessarily controlling it.
One of the enduring lessons from Ukraine’s ongoing Sea of Azov Campaign is that these attacks should be a wake-up call to Moscow that Russian assumptions about the security of its internal waterways, once thought unreachable to attack, are now highly vulnerable. After five years of
war, that illusion is now shattered as Russian planners struggle to deal with the urgent need to reroute Russian grain shipments and cargo to alternative routes away from the Black Sea.
One alternative is the Caspian. Russia has already begun shipping grain to Iran via the Caspian Sea during the ongoing US-Iran War, and Moscow may further pivot its agricultural shipments to Iran via the Caspian to make up for Ukraine’s closure of the Sea of Azov since the Volga Delta empties into the Caspian Sea via Astrakhan. In the first quarter of 2026, 732,800 tons of grain and its processed products were exported by Russia from the Astrakhan region. A Russian pivot to Astrakhan—attempting a desperate castling move to protect its trade in the Caspian while Ukraine puts the Volga basin in check—could further reshuffle what Zbigniew Brzezinski described as the Grand Eurasian Chessboard.
Regardless, Russia’s recent closure of the Sea of Azov is a stark admission by Moscow that Kyiv has put a cork into the southern terminus of Russia’s Volga-Don river system that will likely send shockwaves through international commodity markets as 25 percent of Russian grain exports must now come to a grinding halt. Almost immediately following the news of the commercial navigation freeze, global wheat futures on the Euronext exchange surged by nearly 4%, marking a six-week high. While international trade organizations had long warned that the war posed systemic risks to Black Sea shipping, the total closure of the Azov-Don canal represents the first major, multi-day interruption of Russian grain flows since the Ukraine war began in 2022.
