British Intelligence update on Ukraine as of Mar. 27

On 22 March 2023, at least three uncrewed surface vessels (USV) and one uncrewed aerial vehicle reportedly attempted to strike the Russian naval base of Sevastopol, in occupied Crimea.

Open source reports suggest that one USV was stopped by defensive booms, while two were destroyed in the harbour. Russian officials said that no Russian vessels had been damaged.

A previous USV attack on Sevastopol on 29 October 2022 reportedly damaged the minesweeper Ivan Golubets and the frigate Admiral Makarov.

Even though the new attacks likely failed to damage any military assets, the USV threat likely continues to constrain operations of Russia’s Black Sea Fleet.
