OVERVIEW: The PLA-885M *Severodvinsk* [Yasen-M] is a nuclear-powered cruise missile submarine (SSGN) of the Russian Navy.

DETAILS: The Yasen-M class represents a significant advancement over its predecessor, the Project 885 Yasen. Development of the class was initiated in the 1990s, with the *Severodvinsk* being the lead vessel. The design incorporates stealth technologies, including anechoic tiles and a streamlined hull form, to reduce its acoustic signature. Significant modifications were implemented during the construction process, incorporating advancements in electronics, sonar, and weapons systems. The Yasen-M design emphasizes modular construction, allowing for easier integration of future technologies and upgrades throughout the submarine's service life. The class reflects a shift towards a multi-mission platform capable of engaging a wide range of targets.

The *Severodvinsk* is designed for anti-submarine warfare (ASW), anti-surface warfare (ASuW), and land-attack missions. The advanced MGK-600 Amfora sonar suite, with its flank, towed, and hull arrays, provides comprehensive underwater situational awareness, enabling long-range detection and tracking of enemy submarines and surface vessels. The Snoop Pair [MRKP-58 Radian] radar facilitates surface surveillance and target acquisition. The installation of the 3R-14UKSK-Kh VLS, capable of launching SS-N-26 Strobile, SS-N-27 Sizzler, SS-N-30 Kalibr, and SS-N-33 Granit cruise missiles, provides a formidable land-attack and anti-ship capability at extended ranges. The 533mm torpedo tubes offer a flexible means of engaging submerged and surface targets at closer ranges with a variety of torpedoes and possibly submarine-launched anti-ship missiles. The SA-N-8 Gremlin [9K34 Strela-3] mast launcher provides a limited self-defense capability against aerial threats.

The *Severodvinsk*'s sensor suite is exceptionally comprehensive, allowing for effective operation in diverse and contested environments. The Rim Hat [Kremlin-2] electronic warfare support measures (ESM) system enables the detection and identification of enemy radar emissions, providing critical intelligence for situational awareness and self-defense. The inclusion of both optical and low-light television (LLTV) periscopes enhances situational awareness in both day and night conditions, enabling covert observation of surface targets. The PLA-885M sensor suite likely incorporates advanced processing capabilities for data fusion and threat assessment, providing the crew with a clear and concise picture of the operational environment. The "Generic Acoustic Intercept" sensor suggests the vessel possesses the ability to detect and analyze acoustic signals for intelligence gathering purposes.
