Background
Code-named “Akula” by NATO and Project 971 Щука-Б (Shchuka-B, 'Shchuka' meaning pike) by the Russian Navy, this nuclear-powered attack submarine was first deployed by the Soviet Navy in 1986. In all, 15 Akula class attack boats have been built, spanning 4 distinct subclasses, with the original 7 commissioned between 1984 and 1990, six upgraded boats between 1991 and 2009, and one-each offshoots in 1995 and 2001 respectively.
