By 2020, a fleet of eight Borei and Borei-A subs will be able to carry 148 R-30 Bulava missiles with a total of 1,480 guidance blocks, 100-150 kilotons each.
A Borei-class submarine also has eight 533-mm forward torpedo tubes, nearly 40 torpedoes, missile-torpedoes and torpedo mines. It also carries autonomous sonar countermeasures devices.
Borei’s sonar system allows for detecting enemy ships at a distance 50 percent farther than that of Virginia-class submarines of the United States Navy. This system is a complex of digital devices providing communications, acquisition and detection of targets and a range of auxiliary functions.
A Borei-class submarine has a maximum depth of 480 meters. It carries a 90-days food supply for crew. As for its life-support systems, it can operate autonomously for decades. Its crew numbers 107 members.
In comparison with a Borei and Borei-A submarines, the Borei-M (developed in 2011) submarine has increased stealth capabilities and advanced communications and weapons control systems. There is also a modernization plan for the entire Project 955.
