OVERVIEW: The PLA-971 Akula I [Shchuka-B] is a nuclear-powered attack submarine (SSN) operated by the Russian Navy. Introduced in the late Soviet era, it represents a significant advancement in Soviet submarine technology.

DETAILS:
The Akula I, known internally as Project 971 Shchuka-B, was conceived as a third-generation nuclear-powered attack submarine designed to counter the perceived threat posed by increasingly sophisticated Western submarines, particularly the U.S. Navy’s Los Angeles and Seawolf classes. Development began in the 1970s, and the design incorporated significant noise reduction measures, including extensive use of rafted machinery and anechoic tiles to minimize the submarine's acoustic signature. This focus on stealth was a primary driver in the design philosophy, aimed at allowing the Akula I to operate closer to enemy coastlines and carrier battle groups with reduced risk of detection. The Akula I also benefitted from improved automation and crew comfort compared to earlier Soviet submarine designs.

The primary role of the Akula I is anti-submarine warfare (ASW), with a secondary focus on anti-surface warfare (ASuW). Its advanced sensor suite, coupled with a diverse array of torpedoes and cruise missiles, allows it to effectively engage both surface and subsurface targets. While not primarily designed for anti-air warfare (AAW), the presence of the SA-N-8 Gremlin mast launcher provides a limited self-defense capability against aerial threats. The Akula I's long endurance and deep diving capabilities enable it to conduct extended patrols in distant operational areas.

The Akula I’s sensor suite provides comprehensive situational awareness. The Rim Hat [Kremlin-2] radar provides surface search and navigation capabilities. The Shark Tail [MG-541 Skat-3] and Shark Gill [MGK-540 Skat-3] sonar systems offer both active and passive detection capabilities for locating and tracking submarines and surface vessels. The inclusion of a Generic Acoustic Intercept system allows for the detection and analysis of enemy sonar emissions. The Mouse Roar [MG-519 Arfa-M] hydroacoustic detection system further enhances situational awareness. The Snoop Pair [MRKP-58 Radian] radar enhances long-range surface detection. The two periscopes, one optical and one LLTV (Low Light Television), provide visual and electronic surveillance capabilities. The SOKS (System of Observation of the Condition of the Surroundings) system is used for detecting wakes and other disturbances in the water. The combination of 533mm and 650mm torpedo tubes provides flexibility in deploying a range of anti-submarine and anti-surface weapons. The Signal Ejector would be used for countermeasures and communication.
