 Russian Navy defeated in Black Sea, the British Ministry of Defence believes that the Ukrainian forces managed to defeat the Russian fleet in the Black Sea. James Heapy, Minister of State for the Armed Forces of the UK in a speech at the Warsaw Security Forum, said this. During his speech, the official urged the International Society to appreciate the military achievements of Ukraine highly. Yes, Ukraine's progress is slow, but no one can say that it does not exist. You can point to the Kharkiv breakthrough as a model of success. But look at what Ukraine has done now in the Black Sea. Ukraine has achieved a functional defeat of the Russian Black Sea fleet. James Heapy said, commenting on Ukraine's ground counter offensive, James Heapy pointed out that every inch is important. UK defence intelligence says that the Russian Black Sea fleet will likely not be able to have the same control in the Black Sea waters as before and will also feel less safe in its ports after the latest series of successful Ukrainian strikes. Defence intelligence stated that in recent weeks, the Russian Black Sea fleet has suffered several serious attacks culminating in the attacks on its headquarters on the 20th and 22nd of September. The physical damage to the Black Sea fleet 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. It is, however, likely that its ability to continue wider regional security patrols and enforce its de facto blockade of Ukrainian ports will be diminished. It also likely has a degraded ability to defend its assets in port and to conduct routine maintenance, the analysts say.
