Description: The Project 945A-class submarines, Sierra II class NATO-codename, are intended to engage surface ships, submarines and ground targets using torpedoes, rockets, mines, anti-ship missiles and cruise missiles. Their titanium hull allows them to plunge up to 1,000 meters depth. Torpedoes, missiles, mines and rockets can be released through four 533mm and four 650mm torpedo tubes. Overall performance of Project 945 and 945A nuclear attack submarines is similar to Project 971 class submarines, Akula class NATO-codename.

The Project 945A is an evolution of the proven Project 945 submarine, Sierra NATO-codename and introduced in 1984, with optimized propulsion system for lower noise emission and enlarged hull. The Russian Navy commissioned two Project 945 and two 945A boats between 1984 and 1993. Beginning in 1994 only one Project 945 submarine remains in service with the Russian Navy. In early 2013 the Russian Navy released plans for the upgrade of the two Project 945 boats and their come back to active duty by 2017.
