The Security Service of Ukraine (SBU) conducted a unique naval special operation in the port of Novorossiysk. The Sub Sea Baby underwater drones struck a Russian Kilo-class submarine, causing severe damage and disabling it.
The submarine was carrying four Kalibr missile launchers, which Russia uses to launch attacks against Ukraine. The operation was a joint effort by the SBU’s military counterintelligence service and the Ukrainian Navy.
The value of such a submarine is approximately $400 million, and taking sanctions into account, the construction of a new submarine could cost up to $500 million. The sunken submarine was located in Novorossiysk after SBU naval drones drove the Russian fleet out of Sevastopol.
