The Russian Black Sea Fleet (BSF) has suffered a series of major attacks in recent weeks and on 20 September their headquarters in Sevastopol, Crimea was blown up.
The Ukrainian attacks have been more damaging and more coordinated than ever before in the war.
The British Ministry of Defence (MoD) has said in an intelligence briefing that the Ukrainian cruise missile strikes on the Black Sea Fleet has “degraded” their ability “to defend its assets.”
The MoD said on Tuesday, “The physical damage to the BSF is almost certainly severe but localised.
“The fleet almost certainly remains capable of fulfilling its core wartime missions of cruise missile strikes and local security patrols.”

British intelligence officials believe Russia now has a “degraded ability to defend its assets in port and to conduct routine maintenance.”
The MoD added, “a dynamic, deep strike battle is underway in the Black Sea.
“This is likely forcing Russia into a reactive posture whilst demonstrating that Ukraine’s military can undermine the Kremlin’s symbolic and strategic power projection from its warm water port in occupied Sevastopol.
On Monday Ukrainian Special Operation Forces claimed to have killed Vladimir Putin’s Black Sea Fleet admiral in a Storm Shadow cruise missile strike.
The missile strike killed admiral Viktor Sokolov, 61, in the air strike on Friday along with 96 other people.
The irretrievable losses of highly trained commanders will affect Russia and their operations moving forward and the headquarters is not “subject to restoration.”
