Not to be confused with the Typhoon-Class or the other Akula-Class of the Russian Navy, the Akula-Class (aka Shiuka) is one of many submarine classes serving the Russian Navy and was even leased to the Indian Navy for ten years!
The Akula-Class is a nuclear-powered attack submarine with multiple variations being built since the 1990's with some featuring an extruding bulb on the fin of these machines containing a towed array sonar.
