British intelligence says the threat of surface drones is likely to continue to constrain the operations of Russia's Black Sea Fleet.

 This is stated in the intelligence review of the British Ministry of Defense on March 27.

 As noted, on March 22, at least three unmanned surface vehicles and an aerial drone attempted to strike the Russian naval base in Sevastopol in the temporarily occupied Crimea.

 According to reports from open sources, one surface drone stopped due to defensive boom barriers. Two more destroyed in the bay. Russian officials said no Russian vessels were injured.

 The agency reminded that the previous attack by surface drones on Sevastopol took place on October 29, 2022. Then, according to reports, drones damaged the minesweeper "Ivan Golubets" and the frigate "Admiral Makarov".

 Despite the fact that the new attacks probably did not damage any military facilities, the threat of surface drones is likely to continue to limit the operations of the Russian Black Sea Fleet, the British agency estimated.
