In a historic first, Ukraine’s Security Service used "Sub Sea Baby" underwater drones to disable a Russian Kilo-class attack submarine docked at Novorossiysk, Russia's primary Black Sea naval base. The strike highlighted Ukraine's innovative efforts to challenge Russian naval power, especially after Russia relocated vessels from Crimea to more secure ports. The submarine, capable of launching Kalibr cruise missiles, represents a significant military asset for Russia. The attack underscores Ukraine’s growing drone warfare capabilities amid strained peace negotiations mediated by the U.S., where Ukraine seeks leverage against Russia in talks perceived domestically as conceding too much. This operation not only disrupts Russia’s naval capabilities but also signals a strategic shift in naval combat tactics in this conflict.
