Operation MoLoChKa has now disabled 300 Russian shadow fleet ships in 11 weeks, SBS commander Robert "Madyar" Brovdi announced. The Unmanned Systems Forces (SBS) campaign has frozen the Azov Sea and the Kerch Strait, Brovdi said.

134 in the Azov, 166 in the Black Sea

SBS drones struck 134 vessels in the Azov Sea and 166 in the Black Sea since Operation MoLoChKa began on 6 July, the SBS wrote—all, Brovdi specified, stripped of the ability to move under their own power. He called it the "300th fleet," playing on the Ukrainian army's code for a wounded man, and "a suitcase without a handle and a torment for the worm budget."

The Azov Sea "stands and will stand, together with the Kerch Strait," Brovdi said. The northern and northeastern Black Sea operates on what he called a "maybe we'll slip through" gamble.

The 300-ship count is the latest in a rapid progression. The SBS reported 201 vessels disabled by 29 July—just three weeks into the operation—when Brovdi said Crimea's supply route was "blocked indefinitely." By 11 September, the tally had reached 285, with 215 struck in July, 54 in August, and 16 in the first 11 days of September. The pace slowed as traffic in the strike zone thinned out.

The SBS figures are the unit's own and cannot be independently verified.

Ukraine hits 201 Russian shadow fleet ships in three weeks. Commander says Crimea’s supply route is now blocked indefinitely

Commercial shipping retreating from Russian ports

In late August, MSC Mediterranean Shipping Co., the world's largest container carrier, suspended new bookings for transport through the Russian port of Novorossiysk. Russia itself closed the Don-Azov shipping channel and the Kerch Strait in July after the opening wave of strikes.

By early August, Ukraine had turned Novorossiysk—Russia's main Black Sea export gateway—into a chokepoint, and in mid-August Ukrainian forces struck four Russian warships there in a single night. A 141-meter vessel disappeared near Novorossiysk the same week.

A parallel campaign against Crimea's power grid

The SBS is running a second operation alongside MoLoChKa. Operation Crimean Switch Off, also launched on 6 July, had struck 374 energy nodes across occupied Crimea and other occupied areas in eastern and southern Ukraine by 10 September. The campaign has blacked out Crimea on multiple nights. Brovdi has said the SBS could strike seven times more targets with faster funding.

Russian President Vladimir Putin has moved his flagship foreign policy conference from Sochi to Moscow Oblast amid growing concerns over Ukraine’s long-range drone strikes, the Financial Times reported on 15 September.

The decision is likely an indirect acknowledgment of the impact of Ukraine’s ongoing deep-strike drone campaign. Russian officials may not publicly admit that Ukrainian drones pose a serious threat, but their actions suggest otherwise: Putin has increasingly avoided areas within range of Ukrainian drones, and now a major Kremlin event is being moved out of Sochi because of security concerns.

The annual Valdai Discussion Club meeting was originally planned for Sochi, but the venue was changed after Putin’s security service insisted on the move, according to four people familiar with the decision cited by the FT. Some 120 guests had already received invitations to the Black Sea resort before being informed of the change in August.

Putin has not visited Sochi since the Valdai conference there in early October 2025. Since then, Ukraine has significantly stepped up its long-range drone campaign against Russia. The change is stark compared with 2021, when Putin visited the Black Sea resort 24 times, according to the FT.

Ukraine is targeting the defenses behind Russia’s rear

Ukraine has repeatedly demonstrated its ability to strike targets in Russia’s rear. Its drones have reached energy and logistics infrastructure thousands of kilometers from Ukraine, while Sochi and other areas of Russia’s Black Sea coast have come under repeated attack.

The latest strike came on 13–14 September, when Ukraine’s Defense Forces hit the 92N6 multifunction radar of a Russian S-400 air defense system in Sochi, according to Ukraine’s General Staff. The radar tracks aerial targets and guides the S-400’s missiles, making it a critical component of the system defending the area.

The strike followed a 4 September Ukrainian attack on Sochi that hit two fuel depots and an air defense position near the Abkhazia border. Satellite imagery later showed nine destroyed fuel storage tanks and damage at the air defense position.

Putin’s movements show the threat is changing

The relocation also fits a broader pattern in Putin’s movements. The Russian president has spent much of his time in Moscow, St Petersburg and his residence near Lake Valdai in Novgorod Oblast, while making more trips east of the Urals – areas farther from Ukraine’s long-range drone reach.

The Valdai forum will still take place from 28 September to 1 October, but now in Moscow Oblast rather than Sochi. Putin traditionally attends the final day and holds a lengthy question-and-answer session.

The Kremlin does not need to say Ukrainian drones are a serious threat. Moving Putin’s major foreign-policy forum away from Sochi says it for them.

For the first time, two unmanned boats have fought a battle at sea, and the Ukrainian one sank its Russian rival. The Ukrainian Defense Intelligence has spotted a Russian drone in the Black Sea, and a Sargan-3000 naval drone armed with a remote-controlled machine-gun turret opened fire and destroyed it, the Ukrainian Navy said on Telegram, calling it "the first-ever naval battle between unmanned boats."

Drone-versus-drone combat has moved from the sky to the sea. Ukraine has already rewritten naval warfare with uncrewed boats, sinking warships and pushing much of Russia's Black Sea Fleet back to port without a navy of its own to speak of.

Now it has fought and won the first duel between two robot vessels, a glimpse of automated sea combat. The claim is the Navy's. It released a video of the encounter but did not provide a date, an exact location, or the type of Russian craft, and it has not been independently verified.

A gun turret decides the duel

The Russian vessel was detected by units of the Ukrainian Defense Intelligence, the Navy said, before the Sargan-3000 closed in.

The Ukrainian drone carried an automated 12.7mm Protector remote weapon station, a turret of the same type mounted on some NATO warships, and used it to sink the Russian boat.

The published footage shows the two drones engaging and the Russian craft going under.

The Sargan-3000 reaches far

The Sargan-3000 is a Ukrainian multi-purpose strike drone that passed combat testing in April. It has a combat radius of up to 1,600 kilometers, runs at 40 to 55 knots, and carries up to 450 kilograms of payload, according to Militarnyi.

It is the same class of boat that sank the Russian border patrol ship Izumrud near Novorossiysk in July.

Ukraine keeps rewriting naval war

The battle fits a campaign that has reshaped the Black Sea. Ukrainian sea drones have sunk the corvette Ivanovets (link) and the landing ship Caesar Kunikov (link), in 2025, even shot down a Russian Su-30 fighter jet (link), and in the last ten weeks alone struck 285 vessels of Russia's shadow fleet (link).

Russia is now racing to build its own uncrewed fleet, and satellite imagery suggests it is constructing a dedicated naval-drone port in occupied Crimea, a sign that the sea, like the sky, is filling with machines that fight each other (link).

The Netherlands and Belgium have delivered two minehunter vessels to Ukraine to support maritime security in the Black Sea, Dutch Defense Minister Ruben Brekelmans announced on June 26.

"The Netherlands and Belgium are transferring two minehunters to Ukraine. A vital contribution to Black Sea security, and key to safeguarding trade routes and global food supply," Brekelmans said on X. He added that Ukrainian crews and technicians were trained "in record time."

According to the Dutch Defense Ministry, the vessels involved are the Belgian ship BNS Narcis and the Dutch Zr.Ms. Vlaardingen. The official handover ceremony took place earlier in Zeebrugge, Belgium, but was disclosed only later due to security concerns.

"The major ports of Odesa and the Black Sea shipping lanes are the lifeblood of the Ukrainian economy," Brekelmans said. "And (they are) under constant threat. Ukraine may not win the war at sea, but it can certainly lose the war there. We simply cannot let that happen. That is why it is so important for maritime security and free passage that Ukraine can use minehunters."

Since Russia's full-scale invasion of Ukraine began in February 2022, the Netherlands has provided Kyiv with a combined 8.4 billion euros ($9.4 billion) in support, according to the Kiel Institute for the World Economy while Belgium has allocated over two billion euros (about $2.2 billion) in support, including military, financial, and humanitarian assistance.

Putin under pressure to declare war on Ukraine, but experts say Russia isn’t ready

Despite suffering over 1 million casualties, pounding Ukrainian cities nightly with missiles and drones, and committing countless war crimes, one startling fact about Russia’s full-scale invasion remains — Moscow has yet to officially declare war on Ukraine. In February 2022, Russian President Vladimir Putin described what he believed was going to be a swift victory and the capture of Kyiv within days as a “special military operation.” Nearly three-and-a-half years later, the Kremlin is stuck
