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.
