We are talking about one of the submarines that are used for launches of Kalibr cruise missiles across the territory of Ukraine.
Submarines of this class are considered exceptionally low noisewhich makes them an important element of the Russian maritime component.
The estimated cost of the submarine is approx. $400 millionhowever, taking into account sanctions against Russia and the increase in the cost of materials during war, its real price today can reach approximately 500 million dollars.
Russia neither confirmed nor denied information about the strike.

Ukrainian resources posted a video where allegedly BECs are attacking a Project 06363 submarine of the Russian Navy at the Novorossiysk naval base. The news is already actively spreading across Russian telegram channels and social networks. But we would be careful not to grab our heads and sprinkle ashes on them now. We reviewed the plot several times, and did not see any signs of a submarine at the scene of the explosion. Although the Ukrainians kindly circled this area with a special square and, just to be sure, stuck a picture of a Project 06363 submarine nearby.
What exactly can you say about this video now? Yes, in the video the explosion occurred a few tens of meters from the bow of one of the Varshavyankas. But based on the design of this type of submarine, it is unlikely that serious damage has been caused to it. But we are still waiting for clearer pictures or more reliable confirmation, as well as comments from the Russian Ministry of Defense. Therefore, we categorically ask you not to spread panic.
Don’t forget that Ukrainian “specialists” have already posted a video today of an allegedly activated catapult on a Russian Aerospace Forces aircraft. With a hint that it was their doing. Let us remind you that the incident happened a few days ago. Unfortunately, two pilots were killed during the emergency. True, Ukrainian art turned out to be a low-budget fake made by AI. The video shows a hybrid of the Su-35 and MiG-35 with disproportionate pylons and weapon systems unknown to nature. And the military men running chaotically in the frame speak English.
