The Sierra II class submarine is a type of nuclear-powered attack submarine developed by the Soviet Union and currently in service with the Russian Navy. These submarines are considered among the most advanced and formidable underwater vessels in the world, boasting a range of cutting-edge features that make them a significant asset to any naval fleet. Here, we will explore the 10 key features of the Sierra II class submarine.
Advanced Propulsion System
One of the most notable features of the Sierra II class submarine is its advanced propulsion system. The submarine is powered by a single OK-650B nuclear reactor, which produces 190 MW of power. This reactor is paired with a gearbox and a propeller shaft, allowing the submarine to reach speeds of up to 35 knots (65 km/h). The propulsion system also features a pump-jet propulsor, which provides a high degree of maneuverability and quiet operation.
Improved Hydrodynamics
The Sierra II class submarine features an improved hydrodynamic design, with a sleek and streamlined hull shape that reduces drag and enhances stability. The submarine's hull is also coated with a specialized anechoic material that absorbs sonar waves, making it more difficult to detect.
Advanced Sensors and Electronics
The Sierra II class submarine is equipped with a range of advanced sensors and electronics, including a MGK-400 Rubikon sonar system, a MG-519 Arfa-M radar system, and a Tsunami satellite communications system. These systems allow the submarine to detect and track targets at long range, and to communicate with other vessels and shore-based command centers.
Improved Command and Control
The Sierra II class submarine features an improved command and control system, with a centralized control room that allows the crew to monitor and control all of the submarine's systems. The submarine also features a digital combat control system, which allows the crew to quickly and accurately target and engage enemy vessels.
Advanced Armament
The Sierra II class submarine is equipped with a range of advanced armament, including 4 x 533mm torpedo tubes and 4 x 650mm torpedo tubes. The submarine can carry a variety of torpedoes, including the 53-65 torpedo and the 65-76A torpedo. The submarine also features a range of missile systems, including the Kalibr-NK and the Oniks anti-ship missiles.
Improved Stealth Capabilities
The Sierra II class submarine features a range of improved stealth capabilities, including a specialized anechoic coating that absorbs sonar waves, and a sleek and streamlined hull shape that reduces drag and enhances stability. The submarine also features a range of noise-reducing systems, including a propeller shaft and a gearbox that minimize noise emissions.
Advanced Communication Systems
The Sierra II class submarine is equipped with a range of advanced communication systems, including a Tsunami satellite communications system and a MG-519 Arfa-M radar system. These systems allow the submarine to communicate with other vessels and shore-based command centers, and to detect and track targets at long range.
Improved Life Support Systems
