The Greek-run oil tanker Skiros was attacked near Novorossiysk on 16 August 2026 after loading Russian crude at the Caspian Pipeline Consortium (CPC) terminal, Bloomberg reported.

The Suezmax-class vessel can carry about 1 million barrels. Bloomberg identified no attacker and provided no information about damage. Skiros’s Athens-based manager told the outlet that no one was injured and no pollution occurred.

CPC primarily exports Kazakh oil and carries more than two-thirds of Kazakhstan’s oil exports. Its shipments recently accounted for almost 2% of the global oil supply. Russian crude typically makes up only 5% to 10% of CPC exports.

Earlier in August, Ukraine agreed not to attack CPC infrastructure or non-Russian ships bound for the terminal if they were not under Ukrainian sanctions and did not carry Russian cargo. Because Skiros carried Russian crude, the protection did not apply to it under the terms Bloomberg described.

Following the July attacks, CPC considered suspending operations due to environmental and safety risks but decided to continue operations, Bloomberg reported.

The Skiros attack ended an almost three-week lull in attacks on ships using the terminal. Bloomberg did not say whether it disrupted oil loading, and CPC declined to comment.

Earlier attacks cut Kazakhstan’s oil production

Earlier attacks suspended loading at the terminal. Kazakhstan’s Energy Ministry confirmed a temporary reduction in oil production to prevent storage facilities from reaching capacity, while Reuters reported CPC loadings fell by a fifth in July.

The disruption also increased shipping and war-risk insurance costs as some operators became reluctant to call at the terminal, The Financial Times reported.

Paralysis of the logistics

Ukraine has not claimed responsibility for the Skiros attack, and Bloomberg did not identify an attacker. In a separate operation in July, the SBU and Navy acknowledged striking sanctioned Russian oil tankers Louise 1 and Banda with Mamai sea drones.

Robert “Madyar” Brovdi, commander of Ukraine’s Unmanned Systems Forces, later described the wider objective as the “paralysis of the logistics” of oil, fuel, and cargo that bypasses sanctions.

Russia dismissed the idea of a Black Sea ceasefire on 14 August, Reuters reported, a day after the agency disclosed that Ukraine had proposed a mutual halt to attacks on civilian targets there.

Russian Foreign Ministry spokesperson Maria Zakharova said Moscow saw no grounds for measures that would give Kyiv a temporary reprieve.

Russia’s dismissal comes after its strikes drove shipowners from Odesa as Ukraine’s wheat harvest peaked. More than 90% of Ukraine’s farm exports leave through three deepwater Odesa ports. Reuters reported that Ukraine’s 12 August operation at Novorossiysk targeted a naval base and warships, although nearby grain terminals also suspended operations.

Russian forces, by contrast, have repeatedly struck foreign-flagged ships and Ukrainian port infrastructure. The disruption is stranding Ukrainian crops and raising concerns over global food supplies.

Zakharova accused Ukraine of deliberately destabilizing civilian shipping but did not mention Russia’s attacks, Reuters said. She was responding to Turkish Foreign Minister Hakan Fidan, who said Ankara had proposed a Black Sea moratorium to both sides.

Zakharova also said Moscow had received no formal proposal from Türkiye and ruled out reviving the 2022–23 Black Sea grain deal, calling it one-sided.

Ukraine’s harvest has nowhere to go

Reuters said Ukraine’s grain exports had fallen 76% year on year so far in August. Ukraine’s Agriculture Ministry projects agricultural exports could nearly halve, from 64.4 million to 29.6 million tonnes. It expects silos to fill by October as grain backs up.

World Grain, citing the US Department of Agriculture’s Foreign Agricultural Service, reported that corn exports could fall 39% and wheat exports 26%. The US agency expects unsold corn stocks to rise more than tenfold.

The ministry has asked the EU for €220 million to subsidize farm loans and help producers finance autumn sowing. Reuters separately reported, citing unnamed sources in both countries, that Kyiv and Chisinau were discussing a rail route to Romania’s Constanța port. Kyiv estimates it could carry only 10% of Ukrainian grain exports.

Russia turns ports into targets

After Russia refused to extend the UN- and Türkiye-brokered grain deal in 2023, Ukraine opened its own maritime corridor. It remained operational until this summer’s escalation.

Russian forces repeatedly struck foreign-flagged vessels in July. On 19 July, Russian missiles hit the Guinea-Bissau-flagged, Turkish-owned Golden Leo as it left Odesa carrying corn. The attack killed 10 people, Ukraine’s Navy and Sea Ports Authority said. Ag Bull Trading reported that the attacks brought the corridor to its first full stop since it opened in August 2023.

Russia’s dismissal leaves Ukraine’s corridor officially open while Russian attacks continue to drive shipowners away.

Ukraine struck the Novorossiysk naval base in Russia's Krasnodar Krai overnight on 12 August, and for the first time coordinated more than 15 different strike systems in a single operation, President Volodymyr Zelenskyy said. The package combined Palianytsia jet drones, Neptune anti-ship missiles and naval drones, hitting warships, air defenses and oil infrastructure at the Black Sea Fleet's main base.

Novorossiysk is the refuge Russia's fleet fled to after Ukrainian drones and missiles pushed it out of occupied Crimea. Reaching its warships there with a mixed salvo — and getting through air defenses that bystander footage showed firing heavily — is the operational read the strike carries, more than any single ship damaged.

The systems and the targets

Zelenskyy named more than a dozen systems that worked together for the first time, from the Palianytsia and Peklo drones to the long-range Neptune and a set of naval drones. He thanked weapons developers for the added reach, framing the coordination itself as the milestone rather than the results.

The Security Service of Ukraine (SBU) confirmed hits on two Kalibr-carrying frigates, the Admiral Essen and Admiral Makarov, and the patrol ship Vasily Bykov. The same strike hit an S-300 radar, a firing position on one of the port's piers, the Sheskharis oil terminal and three of the harbor's berths — a target list wider than the ships alone.

How many ships

The three Ukrainian accounts agree on the two frigates but not on the full tally. The General Staff counted four warships, adding a Buyan-M missile ship to the SBU's three. Zelenskyy separately cited a large landing ship and a corvette among the vessels hit.

Independent analysts who reviewed satellite imagery told The Maritime Executive the damage did not appear catastrophic, with no ships visibly burning or sinking. Ukraine's General Staff said the assessment is still under way.

The fleet's shrinking refuge

The strike extends a campaign that has driven Russia's fleet eastward without Ukraine fielding a navy of its own. Having lost safe basing in Sevastopol, Russia moved its ships more than 300 kilometers from the front — far from Ukraine, but no longer out of reach.

The operation's footprint reached past the base. Russian authorities in Novorossiysk declared a state of emergency and cut water to the port city, and the strike on the Sheskharis oil terminal hit infrastructure that helps fund the war. Zelenskyy said Ukraine would keep striking such targets, and that Russia alone can end the war it started.

Ukraine reached the port where Russia's Black Sea Fleet took shelter and hit four of its warships. On the night of 12 August 2026, in a joint operation, Ukraine's Defense Forces struck the naval base at Novorossiysk in Russia's Krasnodar Krai, the General Staff reported.

Novorossiysk became Russia's main Black Sea naval base after Ukrainian strikes and sea drones drove the fleet out of occupied Sevastopol in Crimea, so reaching its warships there strikes at the refuge that was supposed to be safe.

The ships that were hit

The four vessels are among the fleet's more capable surface combatants. The two Project 11356 frigates, Admiral Makarov and Admiral Essen, are among the newest and most important surface ships Russia has kept in the Black Sea, both capable of launching Kalibr cruise missiles at Ukraine.

The Buyan-M is another Kalibr shooter. The Project 21631 small missile ship carries the same cruise missiles Russia fires at Ukrainian cities, and the Vasily Bykov is a patrol ship of the class Ukraine has struck before, so the strike damaged both major missile-carrying combatants and a patrol vessel in one night.

The overall damage at the base is still being assessed.

The fleet has no safe harbor left

The strike extends a campaign that has steadily pushed Russia's fleet eastward and out of action. Ukraine drove the Black Sea Fleet from Sevastopol without a navy of its own, using drones and missiles, forcing Russia to pull its ships back to Novorossiysk, farther from Ukraine but not out of reach.

This means that Russia holds no waters it can use and now no harbor where its ships are safe. Ukraine's Defense Forces said they consistently reduce Russia's capacity to continue its armed aggression, and damaging four warships at their fallback base is the naval form of that pressure.

Overnight on 7 August, a vessel was possibly sunk in the Black Sea near Novorossiysk, the Ukrainian monitoring channel Exilenova+ reports. The project, which spotted the ship in satellite imagery, suggests it may have been carrying military cargo.

Russia has a practice of concealing its fleet losses. Moscow tries to mask the scale of the problem in various ways: it classifies sinkings as accidents, downplays the number of casualties, or stays completely silent about vessel losses. Russia acknowledges fleet losses only when it happens accidentally or when concealing the sinking or damage is no longer possible. The 141-meter vessel, which had no foreign owner to demand explanations, has received none.

Russian officials have not commented on the sinking, Exilenova+ says.

"The news passed quite modestly, but there is a nuance. Russia's 'official' authorities have not reported about any sunken vessel. It just sank. It is not ruled out that the ship was carrying military cargo for Russia's armed forces. Otherwise, why pretend nothing happened?" Exilenova+ wrote.

The vessel was approximately 141 meters long, suggesting a displacement of roughly 10,000 tonnes, according to the Ukrainian outlet Militarnyi.

The strikes that may have caused the sinking

Over 48 hours on 6-7 August, the Unmanned Systems Forces (SBS) struck 102 enemy targets, SBS Commander Robert “Madyar” Brovdi reported. In the same post, he noted that the targets included six shadow fleet vessels in the Black and Azov Seas: two tankers and four dry cargo ships. The SBS also reported striking three units of Russia's fleet on 7 August alone.

"It is entirely possible that the vessel that sank near Novorossiysk is among those struck in those days”, Militarnyi suggests.

Novorossiysk under fire again on 12 August

Just hours after the news of the earlier reported sinking surfaced publicly, Novorossiysk came under attack. Overnight on 12 August, Ukraine's defense forces conducted what President Zelenskyy called a "unique operation" against the naval base, using Palianytsia jet drones, Neptune missiles, and unmanned naval systems.

Novorossiysk became Russia's primary Black Sea naval hub after Ukrainian strikes forced the fleet out of Sevastopol.

Satellite imagery has confirmed that Ukraine's Defense Forces destroyed a Russian electronic-warfare system built to jam Starlink at Gelendzhik in southern Russia, the Ukrainian defense outlet Militarnyi reported. Ukrainian drones hit the machine on the grounds of a Russian border-guard base during their sweep of the Black Sea coast. It is one more of these costly jammers Russia has lost, even as Ukraine's long-range drones cannot use Starlink over Russia.

Satellites caught the before and after

Satellite images published by the OSINT community Dnipro Osint show the site cleared at Gelendzhik, in Russia's Krasnodar Krai. The Volna Kupol Garant complex is gone. Researchers called it the third destruction of this jammer recorded in open sources. The strike landed on the grounds of military unit 2156, the Novorossiysk border detachment of Russia's FSB Border Service.

Ukrainian drones likely hit it alongside a 7 August strike on cargo ships near Novorossiysk and Gelendzhik. Geolocated photos from residents point to a repeat strike on the base on 8 August.

Ukraine’s newest drones don’t need Starlink. Russia spends $1.5 million to jam it anyway.

The Volna Kupol Garant is built from trailers carrying satellite antennas. It tracks a passing Starlink satellite and beams a strong signal that scrambles the terminals below across up to 20 km². Starlink is the SpaceX satellite-internet network that Ukrainian drones rely on to reach their operators. Each unit costs about $1.8 million. A same-named firm registered in occupied Simferopol builds it. The developer also makes the Volna 3M jammer that Russia has fitted to Mi-8AMTSh helicopters to block drone satellite navigation.

Ukraine has knocked out these jammers before. The 422nd Unmanned Systems Regiment, the Security Service of Ukraine's (SBU) Alpha special-operations center, and other Ukrainian units have struck such systems, including in occupied Crimea. The complex's weakness is its own power: beaming enough energy to reach a satellite makes it loud and easy to find.

And deep inside Russia, there is little Ukrainian Starlink to jam — SpaceX geofences the network to Ukrainian territory, and Elon Musk has refused Kyiv's push to use it for strikes into Russia so far.

The wider hunt

Ukraine's drone crews have spent 2026 tearing into Russia's air defenses and rear. The same run of Black Sea strikes that wrecked this jammer also burned a Russian S-400 air-defense system on the Gelendzhik coast. 

Ukrainian aerial- and sea-drone attacks have turned Russia's busiest seaport into a place cargo ships increasingly refuse to sail, choking both imports from China and exports of grain and oil, according to The Moscow Times. Logistics and trade executives describe a route to Novorossiysk grown too risky to use, and a Russian grain-industry group warns the Black Sea export corridors could shut down entirely. The strikes that once spared container ships have now reached them too.

The China route importers are told to skip

"On the China–Novorossiysk route everything is now difficult, the delays are huge," one importer told The Moscow Times. 

Freight forwarders now tell clients to avoid the route outright, three colleagues said. Aerial drones and unmanned boats make the approaches too unpredictable. Earlier strikes fell mostly on grain carriers and oil tankers. Ukrainian drones hit a container ship carrying imports in late July. Then, overnight on 1 August, a sea drone sank the FESCO vessel Yanina about 130 miles offshore. The crew got out. The cargo did not.

Sailings drop as the campaign widens

Large-ship sailings from Novorossiysk fell 38% in July, the Moscow Times says, citing ship-tracking data, with tanker runs down by half. 

"But now the situation will get worse, because container ships have also become a target," a logistics manager told the publication. 

This is one edge of a wider Ukrainian drone campaign against Russian shipping, codenamed MoLoChKa. The name is an acronym for "Moscow will fall through Crimea." Its own public scoreboard counts 206 vessels hit in July by the Unmanned Systems Forces (SBS) alone, with another logged in August. The SBS have mostly burned the small tankers and support ships that keep Russia's sanctioned shadow fleet moving.

What Russia stands to lose

Novorossiysk carries every fifth ton of Russia's seaborne exports: Urals oil, Kazakh crude, wheat for Egypt, and fertilizer for Asia and Africa. 

Attacks across the Azov–Black Sea region could cost Russia up to 30–35 million tons of wheat exports this season, a grain-exporters' union estimated. That would gut a harvest analysts expected to top 44-45 million tons. 

"Systematic attacks that began in July could soon lead to the complete blocking of the export corridors of the Black Sea basin," the union said. 

Ukraine's drones had already cut into Russia's seaborne grain trade this summer, and repeated hits on the port's main oil terminal have dented crude loadings. Russia keeps pouring money into the port, building a new terminal worth 120.7 billion rubles (about $1.5 billion), even as ships stay away, The Moscow Times said.

Russia is changing the drones it attacks with, and hiding the ships it can no longer use. Russian forces are using more jet-powered drones in their air attacks, effectively betting on them, Ukrainian Navy spokesman Dmytro Pletenchuk said, according to UkrInform.

The shift is toward faster, harder-to-stop drones. Russia is reducing the number of ordinary drones and increasing the jet-powered ones, betting on them first and foremost.

Jet-powered Shaheds fly faster than propeller models, giving air defenses less time to react, and Russia has used them in recent strikes, including the 1 August attack that killed a warehouse worker at the retailer Rozetka. Ballistic missiles, Pletenchuk added, remain the main challenge.

The Black Sea Fleet no longer goes to sea

Russia also still claims control of waters it cannot use. The Russians believe they exercise operational control over the Black Sea, but if you look at it purely in terms of sea sorties, they are absent, Pletenchuk said.

"The Azov Sea is out of the question now, and the Black Sea, effectively, the same," he stressed.

Russian aviation remains present and is a problem because it allows Russia to at least map the situation and makes the sea dangerous, but the fleet itself has been driven from the water.

Russia is afraid to repair its own ships

The most striking detail is what has happened to ship maintenance. Russia has repair facilities in occupied Crimea, but does not dare enter and repair ships there, because it has already learned how such repairs end.

They end with the Navy and the Armed Forces adding the "final touches," he said, so Russia periodically tows ships between bays to keep them from being finished off. Novorossiysk has some repair capacity, but docking there is very risky because a ship under repair becomes a stationary target. In practice, no one does it there either. As for small craft like Raptor and Grachonok boats, they are caught during rotations to the occupied spits and destroyed when they come into view, he added, sometimes turning back mid-route, the only patrol vessels Russia still uses.
