The Security Service of Ukraine conducted another special operation and staged a maritime ‘cotton’ in the port of Novorossiysk.
For the first time in history, Sub Sea Baby underwater drones blew up a Russian 636.3 Varshavianka-class submarine (classified as Kilo by NATO). As a result of the explosion, the submarine suffered critical damage and was effectively put out of action, according to the SBU.
The submarine carried four Kalibr cruise missile launchers, which the enemy uses to strike Ukrainian territory.
This was a joint operation by the 13th Main Directorate of Military Counterintelligence of the SBU and the Ukrainian Navy.
The cost of a Varshavianka-class submarine is approximately $400 million. Given the international sanctions in place, the construction of a similar submarine could now cost up to $500 million. This class of submarines is also known as the ‘Black Hole’ because of the hull’s ability to absorb sound and remain undetectable by sonar.
It should be noted that the blown-up boat was forced to remain in the port of Novorossiysk due to successful special operations by Sea Baby surface drones, which drove Russian ships and submarines out of Sevastopol Bay in the temporarily occupied Crimea.
