Diesel-electric submarines (diesel-electric submarines) of Project 636.3 “Varshavyanka” (according to the NATO system – Improved Kilo) of the Russian Navy are still the subject of fierce controversy at sea due to their secrecy. About the advantages of submarines speak columnist for the American edition of 19FortyFive Jack Buckby.
“The Kilo class continues to have a rather fearsome reputation, especially among Western navies, due to a series of acoustic stealth characteristics that make them difficult to detect in coastal waters,” the document said.
The author recalls that Project 636.3 submarines are considered the quietest diesel-electric submarines of their generation. Because of their invisibility, they are called “Black Holes”. The submarines are equipped with low noise levels, effective soundproofing and anti-vibration systems, and rubber hull coatings that reduce sound signatures. As Buckby writes, thanks to this, “Varshavyankas” can “bypass” enemy detection systems.
In early December, it was reported that the Russian Navy had raised its flag on the diesel-electric submarine Velikiye Luki of Project 677M Lada. The third Project 677 submarine is launched in 2022.
