The Russian navy's Black Sea Fleet has been forced to rebase nearly all its combat-ready warships from occupied Crimea to other locations, and its main naval hub is becoming ineffectual because of attacks by Kyiv, Ukraine's navy chief said.
Vice-Admiral Oleksiy Neizhpapa said Ukrainian missile and naval drone strikes had caused heavy damage to the Sevastopol base, a logistics hub for repairs, maintenance, training and ammunition storage among other important functions for Russia.
"They were established over many decades, possibly centuries. And clearly they are now losing this hub," Neizhpapa told Reuters in a rare interview in the port city of Odesa ahead of Ukraine Navy Day on Sunday.
UKRAINE'S ARMY RETREATS FROM POSITIONS IN STRATEGIC TOWN AS RUSSIAN TROOPS CLOSE IN
More than 28 months since Russia's full-scale invasion, Kyiv has dealt a series of stinging blows to Moscow in the Black Sea although Ukrainian ground troops are on the back foot across a sprawling front.
Ukraine, which has no major warships at its disposal, has used uncrewed naval boats packed with explosives to target Russian vessels, and pounded the fleet's facilities and other military targets on Crimea with Storm Shadow and ATACM missiles.
"Almost all the main combat-ready ships have been moved by the enemy from the main base of the Black Sea Fleet, and the ships are kept in Novorossiisk, and some of them are kept in the Sea of Azov," he said.
Russia's Novorossiisk naval base on its eastern Black Sea coast lacks the extensive facilities of Crimea's Sevastopol, which served as the storage and loading site for cruise missiles used by its warships to launch air strikes on Ukraine, he said.
"I understand that they are now trying to solve this problem in Novorossiisk," he said, describing this as a "main issue" for the fleet.
Russia's defense ministry did not respond to a Reuters request for comment on Neizhpapa's remarks.
President Vladimir Putin told navy chiefs last month that Russia's fleet had been replenished over recent years and that a major modernization was under way, including steps to "increase the combat stability of the fleet" and strengthen it.
Alongside strategic bombers and ground-based launchers, missile-carrying warships and submarines play an important role in Russia's regular long-range missile attacks.
Neizhpapa said Ukraine had destroyed or damaged 27 naval vessels, including five that he said were destroyed by sea mines laid by Ukrainian naval drones near the Bay of Sevastopol.
Moscow seized and annexed Crimea from Ukraine in 2014. Before February 2022, Russia used its Black Sea Fleet, which consists of dozens of warships, to project power into the Mediterranean and the Middle East.
Throughout the Ukraine war, Turkey, which controls the straits in and out of the Black Sea, has not allowed warships to enter or exit.
In a sign of their more defensive posture, some Russian warships that seldom entered the Sea of Azov to the east of Crimea are now stationed there regularly, Neizhpapa said.
Monitoring data compiled by the Ukrainian Navy and provided to Reuters showed that as of June 27, 10 Russian warships were stationed in the Sea of Azov compared with none in 2023.
The Black Sea Fleet is primarily used now for logistics, a small amount of coastal territorial control and for firing Kalibr cruise missiles at Ukraine, he said.
He declined to say what Ukraine's future plans in the Black Sea would involve.
Ukraine's operations in the Black Sea have allowed it to establish and secure its own shipping corridor without Russia's blessing after Moscow pulled out of the wartime food export deal brokered by the United Nations last year.
The pushback began with Ukrainian coastal defenses that allowed it to force naval vessels away. In April 2022, Ukrainian anti-ship missiles sank the Moskva, the flagship of Russia's Black Sea Fleet, in a humiliating blow for the Kremlin.
With the addition of naval drone attacks and strikes, Russian warships do not enter the northwestern part of the Black Sea over an area of almost 9,650 square miles, Neizhpapa said.
He said the delivery of U.S.-made F-16 fighter aircraft, expected to happen soon, would be a boost allowing it to challenge what he called Russia's "full dominance" of the skies over the Black Sea.
"F-16s with the right armaments will be able to push away Russian warplanes. The northwestern part of the Black Sea, particularly the corridor for civilian ships, will be almost 100% secure," he said.
He added that Ukraine would like to expand its shipping corridor, which currently only involves maritime traffic from three of the main Odesa ports, to include the ports of Mykolaiv and Kherson, but that it was not possible.
He cited Russia's control over the Kinburn Spit, which juts out along that route.
Civilian vessels are accompanied by patrol boats in some areas to help with protection against mines, and air defenses provided cover both to the ports and the corridors, he said.
The volume of cargo through the corridor has stabilized over the last six months, with Ukraine operating two daily convoys of vessels in comparison with one in 2023.
