#Black Sea

A Ukrainian underwater drone strike that crippled a Russian Kilo-class submarine has forced Moscow to physically block access to a key Black Sea naval harbor, effectively trapping its own warships and underscoring the growing reach of Ukraine’s maritime campaign.

A Ukrainian underwater drone struck and critically disabled a Russian Project 636.3 Kilo-class submarine inside the Novorossiysk naval base. Ukrainian analysts say the strike effectively removes the submarine from service due to Russia’s inability to repair submarines in the Black Sea, while blast fragments from the explosion may have also damaged a second submarine moored nearby.
