Pr. 636 Kilo class submarine. USSR/Russia. 1981

The boats are mainly intended for anti-shipping and anti-submarine operations in relatively shallow waters. Kilo class submarines are capable of operating very quietly. Project 636, sometimes called by the US Navy "The Black Hole" for its uncanny ability to "disappear", is thought to be one of the quietest diesel-electric submarine classes in the world.
