The report states that the cost of a Varshavyanka-class submarine is about 400 million US dollars. Given the imposed international sanctions, the construction of a similar submarine can currently cost up to 500 million dollars. This class of submarines is also known as the "Black Hole" due to the hull's ability to absorb sounds and remain inconspicuous to sonars.
It should be recalled that the blown-up boat was forced to stay in the port of Novorossiysk due to successful special operations of "Sea Baby" surface drones, which displaced Russian ships and submarines from Sevastopol Bay in temporarily occupied Crimea.
