In December 2025, Ukraine's Security Service (SBU) claimed responsibility for a drone strike on a Russian Kilo-class submarine located in the port of Novorossiysk. The SBU stated that the attack, carried out by Sea Baby drones, caused critical damage to the submarine, effectively disabling it. The submarine, according to the SBU, was equipped with four Kalibr cruise missile launchers used to strike Ukrainian territory. The announcement came amid diplomatic efforts to resolve the conflict, with Ukraine seeking to demonstrate its ability to inflict damage on Russia. A Ukrainian navy spokesperson called the attack a turning point in the naval battle between the two countries. Russia has not yet commented on the claim.
