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.

Ukraine struck a Russian drone-control relay station and two other military targets in occupied Crimea and the occupied south overnight on 12 August, its General Staff said. Explosions rolled across the peninsula through the night, Sevastopol declared repeated air-raid alerts, and towns across occupied Crimea lost power, according to Ukrainian monitoring channels and Russian occupation authorities. 

Russia launches its attack drones at Ukraine from sites inside Russia and across occupied territory every day, and relay stations let it steer those drones over long distances. Occupied Crimea is the logistical spine of Russia's hold on southern Ukraine, the funnel through which fuel, ammunition, and reinforcements reach the front, and its fixed airfields, power plants, and control stations sit within reach of Ukraine's growing long-range arsenal.

What the General Staff says was hit

Ukraine's Defense Forces struck three targets overnight, the General Staff reported. The first was a ground relay station used to control Geran and Gerbera attack drones near Olenivka in occupied Crimea. The others were a Russian repair unit near Mariupol in Donetsk Oblast and a staging point for an enemy drone unit near Marivka in Luhansk Oblast.

Hitting these sites weakens Russia's ability to command its attack drones, keep its military vehicles running, and sustain its units, the General Staff said. 

Euromaidan Press could not independently verify the strikes and damage.

Russia flies these drones through a chain of ground repeaters, often mounted on mobile-operator towers or similar tall structures, boost the control signal so operators inside Russia can steer Geran and Gerbera drones over Ukraine from hundreds of kilometers away. Kyiv has dismantled similar relay networks before, including one Russia had built on towers and rooftops in Belarus.

Explosions and blackouts across occupied Crimea

Sevastopol declared three air-raid alerts, and the Russian-installed governor Mikhail Razvozhaev claimed Russian forces downed more than 30 drones, with the heaviest activity over the Balaklava district and no one hurt.

The Ukrainian monitoring channel Krymsky Veter reported explosions in Feodosia and Kerch, and drones close to the Kacha and Belbek airfields. Residents reported air-defense activity near major cities.

The channel said explosions sounded near the Balaklava thermal power plant, a mobile gas-turbine station, and a substation in Sevastopol. Power cut out across parts of occupied Crimea, leaving Sevastopol, Simferopol, and several more cities and districts without electricity.

After the attack, Krymsky Veter's monitoring group reported two large fires near Sevastopol, citing satellite data. One sat by a road junction near the village of Pervomaiske under Balaklava, where a bridge crosses the railway. The other burned near one of the local beaches. The group also logged an already-extinguished fire in the Inzhyr tract that had been reported the day before.

The same night, Ukraine also struck Russia's naval base at Novorossiysk, the fleet's main Black Sea base since late 2023.

Part of the campaign to isolate Crimea

The overnight strikes fit Ukraine's months-long effort to cut occupied Crimea off from the forces and supplies that sustain it. Ukrainian drones have severed road and rail links to the peninsula, left it rationing fuel under rolling blackouts, and pushed the campaign onto the sea by hunting the tankers that supply it.
