Ukraine carried out one of its farthest uncrewed surface vessel (USV) attacks from Ukrainian shores, striking the Nefrit, a multipurpose offshore vessel, in the Russian Black Sea resort city of Sochi. The seaside getaway is located about 350 miles on a direct line from the nearest Ukrainian-held territory, but the trip is a lot longer if originating from Ukrainian-held shores.
This marks the first known USV attack on this city that Russian President Vladimir Putin often visits. As we have reported in the past, it has been attacked several times by Ukrainian aerial drones.
The Ukrainian Navy said it carried out the attack as part of the country’s campaign against Russia’s energy infrastructure. The Nefrit supported that infrastructure, the Ukrainian Navy claimed.
“The multipurpose support vessel, flying the Russian flag, was hit by an unmanned naval vessel of the Ukrainian Navy,” the service said on Telegram. “A powerful explosion and smoke were observed in the area of the vessel.”
“The NEFRIT is part of Russia’s maritime and energy infrastructure, providing support for oil and gas operations, servicing offshore facilities, transporting cargo and personnel, and carrying out underwater technical work,” the Ukrainian Navy explained. “Its activities directly supported the enemy’s war economy and financed the criminal aggression against Ukraine.”
“The damage to the NEFRIT is a blow to the enemy’s logistics, special capabilities, and military-economic infrastructure,” the Ukrainian Navy added. “The Ukrainian Navy continues to deprive the enemy of resources and capabilities for waging war, and once again demonstrates that even Russian territory is not a safe haven.”
While the Ukrainian Navy claimed the Nefrit was damaged, the extent of that is hard to determine from imagery emerging on social media.
Some video, shot from inside the city, shows a large explosion at the port.
A still picture shows smoke wafting from the Nefrit; however, the quality of the image makes it hard to determine the vessel’s condition.
There is also video of one of the USVs being destroyed before it could reach its target.
Starting at about 6 a.m. local time, Sochi Mayor Andrey Proshunin declared an emergency.
“ATTENTION! THREAT OF A USV ATTACK IN SOCHI,” he warned on Telegram. “All forces and resources are working to defend the city. Take shelter in a safe place, remain calm.”
About a half hour later, Proshunin issued an all-clear notice, but did not provide any details about what happened.
There was no immediate response from the Kremlin.
Ukraine has carried out long-distance USV attacks on Russian Black Sea targets in the past, including one in 2023 on the Ropucha class vessel Olenegorsky Gornyak, located in Russia’s Black Sea port of Novorossiysk. A major Russian port on the eastern coast of the Black Sea, it sits roughly 420 miles from Ukrainian-held shores. Sochi is about 110 miles southeast of Novorossiysk, meaning the USVs in today’s attack would have had to travel an even longer distance if launched from Ukrainian-held shores. However, the launch point of the Sochi USV strike is not publicly known and there is always the possibility that a mothership could have been used.
The attack occurring during broad daylight is also interesting, as Ukraine has often taken advantage of the cover of darkness for USV strike operations on port facilities.
You can see a video of that strike below:
The strike on the Nefrit is the latest in Ukraine’s long-running drone boat campaign in the Black Sea. This onslaught has already kept Russia’s Black Sea Fleet (BSF) at bay, forcing it to retreat from Crimea to Novorossiysk. Ukrainian USVs have also damaged enemy military facilities in occupied Crimea and the Kerch Bridge.
The Houthi rebels of Yemen actually pioneered the operational use of kamikaze USVs years ago. We first reported about this capability in January 2017, when an explosive-laden Houthi USV struck a Saudi frigate. Before that, Iran developed various crude kamikaze USVs and those capabilities soon migrated to their Houthi proxies, which put them to use in the Red Sea for the first time.
In July, the U.S. military used USVs as combat weapons for the first time, striking Iranian targets in Bandar Abbas. The following video shows that attack.
It may be a day or so before we get a better picture of the extent of the damage to the Nefrit. Regardless, the attack itself is another sign that Ukraine can reach targets with sea drones far from its own shores.
The Latest
All across the battlefield, Ukrainian forces are largely holding off continued Russian attacks or are making small advances. Overall, in August, “Russian forces advanced or infiltrated into about 123.53 square kilometers — an average pace of 3.98 square kilometers per day,” according to the Institute for the Study of War (ISW). “Russian forces’ main territorial gains in August 2026 have been in the Fortress Belt area, Donetsk Oblast. Even there, Russian forces managed to achieve only marginal tactical gains and have thus far failed to complete the seizure of Kostyantynivka.”
Here are some key takeaways from the ISW assessment.
- Kharkiv: Russian forces continued offensive operations in northern Kharkiv Oblast and the Velykyi Burluk direction on September 1 and 2 but did not advance. Russian forces also continued offensive operations in the Borova and Kupyansk directions on September 2 but did not advance. However, Moscow’s troops continued attempts to secure and expand the bridgehead on the left bank of the Oskil River to enable further infiltrations into Kupyansk.
- Donetsk: Ukrainian forces recently defeated a Russian infiltration mission in the Slovyansk direction. They also recently maintained positions or advanced in the Dobropillya tactical area. Russian forces continued offensive operations in the Novopavlivka direction on September 1 and 2 but did not advance. Neither Ukrainian nor Russian forces reported ground activity in the Oleksandrivka direction on September 2.
- Zaporizhia: Russian forces continued offensive operations in the Hulyaipole direction on September 1 and 2 but did not advance. Russian forces continued offensive operations in western Zaporizhia Oblast on September 1 and 2 but did not advance as Ukrainian forces counterattacked west of Orikhiv.
- Kherson: Neither Russian nor Ukrainian forces reported ground activity in the Kherson direction on September 2.
Air traffic around Moscow continued to be disrupted on Thursday as Russian authorities responded to another large-scale Ukrainian drone operation, according to EU Today. The disruptions came two days after President Volodymyr Zelensky warned international airlines and insurers that Russian airspace was becoming increasingly unsafe for civilian aviation due to Ukrainian drone attacks.
Moscow Mayor Sergei Sobyanin said that 548 drones had flown towards the wider Moscow region between 8 a.m. on Wednesday and midday Thursday local time. However, Russian authorities claimed that most were intercepted before they could reach the Moscow area while 143 were destroyed on approaches to the Russian capital.
“Temporary restrictions were again imposed at Moscow’s principal airports,” EU Today noted. “Vnukovo and Domodedovo stopped arrivals and departures for periods during the operation, while Sheremetyevo handled flights under additional restrictions. The measures produced cancellations, delays and diversions extending beyond the periods in which individual airports were formally closed.”
The disruption “had already become extensive on Wednesday,” the publication added. “Flight-tracking data showed 21 cancellations and 235 delayed services at Sheremetyevo, Russia’s largest airport, while Vnukovo recorded 22 cancellations and 94 delays.”
Putin on Thursday said there is a chance of resolving the “Ukrainian conflict” but Kyiv’s campaign to shut down Russian airspace is “complicating the negotiation process.”
Russia and Ukraine themselves must reach an agreement, while other countries can only support and assist, the Russian leader added, according to a translation from former Ukrainian government official Anton Gerashchenko.
Russia is in contact with the White House and President Donald Trump “is committed to positive and constructive engagement,” Putin proclaimed. “Russia has many friends in the United States. One of them is Steven Seagal, the ‘best envoy of peace.'”
A Russian drone strike on an Odesa apartment building injured at least 17 people, including three children, Zelensky stated on X.
Overall, Ukraine says its air defenses downed or suppressed 135 of 163 Russian drones launched overnight, including Shahed-type UAVs, about half of which were jet-powered. Russia also used S-8000 Banderol, Gerbera and decoy drones. Hits were recorded at 15 locations and debris fell at four.
Russia has been increasingly using jet-powered drones to attack Ukraine. The Ukrainian Defense Ministry released video it says shows troops from the 208th Anti-Aircraft Missile Brigade downing one of those drones. The jet powered Shahed-like one-way attack drones fly higher and faster than their propeller-driven cousins, making them harder to intercept by more cost effective and plentiful means, such as Ukraine’s many drone interceptors. Instead, much more expensive and increasingly scare missile must be used in some circumstances.
What appears to be the first video of Ukrainian troops using Cold War-era Leopard 1 tanks with turrets swapped out for the Rheinmetall Skyranger 35 short-range air defense system has emerged on social media. The @deaidua X account that tracks German war materiel donations to Ukraine said the 1020th Anti-Aircraft Missile Regiment recently took delivery of this system, designed to be a highly mobile counter to a range of aerial threats.
The Skyranger 35 “is equipped with a KDG 35/1000 revolver cannon in 35 mm x 228 caliber with a firing rate of 1,000 rounds per minute,” according to Rheinmetall, which began delivering these to Ukraine in January. “It has an effective range of up to 4,000 meters and a high degree of commonality with the Oerlikon Revolver Gun Mk 3. Thanks to AHEAD technology, the Skyranger 35 is airburst-capable. In the future, it will also be possible to equip it with modern guided missiles.”
A new documentary about Ukraine’s use of the combat-proven National Advanced Surface-to-Air Missile System (NASAMS) air defense system debuts tomorrow.
“Sky Defenders is a new documentary taking audiences inside the increasingly critical battle to protect the skies of Europe and Ukraine,” according to the film’s producers. “Launching globally on Apple TV and Amazon Prime on Sept. 4, the 50-minute film explores the people, technology and strategy behind modern air defense and the race to stop missiles and drones before they reach their targets.”
A new video shows a Russian soldier being attacked by three Ukrainian kamikaze drones simultaneously, underscoring just how dense the drone threat has become to troops near the front.
It’s been more than three years since the Russians captured the town of Bakhmut in the eastern Donetsk region after a long battle that incurred a tremendous toll on personnel and equipment on both sides of the fight. New drone video has emerged showing the city remains in ruins, with blocks and blocks of vacant and destroyed buildings.
That’s it for now. That’s it for now. We’ll update this story with new details when they emerge.
