Ukraine blows up Russian submarine using underwater drone – POLITICO

by · POLITICO

KYIV — In another deep-strike attack against Russia, Ukraine blew up a Russian submarine docked in a secure naval base, Ukrainian counterintelligence agency Security Service of Ukraine (SBU) said Monday.

The SBU said it critically damaged the Class 636.3 submarine "Varshavyanka" (NATO reporting name: Kilo) in its home base at the port of Novorossiysk on the Black Sea.

“Ukraine’s underwater drone Sub Sea Baby attacked a Russian submarine. The explosion critically damaged the submarine and effectively disabled it. The submarine was carrying four Kalibr cruise missile launchers, which Russia uses to strike at the territory of Ukraine,” the SBU's press service said, providing video of the blast as evidence. POLITICO could not independently verify the video.
