“Ukrainian underwater drones struck a Russian submarine for the first time on Monday, causing critical damage to the vessel and making it the first publicly acknowledged use of the new class of Ukrainian weapons, according to Ukraine’s domestic intelligence agency. At the time of the attack, the Kilo-class submarine was docked in a Russian Black Sea port near the city of Novorossiysk and carried four launchers for Kalibr cruise missiles, which Moscow regularly uses to attack across Ukraine, the agency said. Kilo-class vessels are not nuclear-powered and do not carry nuclear-armed ballistic missiles. The Russian government made no immediate comment on Ukraine’s claim.” (12/15/25)
