OVERVIEW: The PLARB-955A Borei II [Borey A] is a Russian Federation Navy nuclear-powered ballistic missile submarine (SSBN). Entering service in 2020, it represents an evolution of the Borei-class design, incorporating significant acoustic signature improvements and enhanced combat systems. It serves as a cornerstone of Russia's nuclear deterrent strategy.

DETAILS: The Borei II (Project 955A) program was initiated to replace the aging Delta III, Delta IV, and Typhoon-class submarines, securing Russia's sea-based nuclear deterrent for the 21st century. The design incorporates lessons learned from previous Soviet and Russian submarine programs, with a strong emphasis on acoustic quieting. Changes from the original Borei-class (Project 955) include a redesigned hull for improved hydrodynamics and reduced noise, alongside upgraded electronic warfare and communication suites. The Borei II is intended to ensure a credible and survivable second-strike capability for Russia, operating within the protection of the Russian Navy's layered defense architecture. The vessels are constructed at the Sevmash shipyard in Severodvinsk.

The Borei II’s primary role is strategic nuclear deterrence, achieved through its capacity to launch SS-N-32 SLBMs. However, the submarine also possesses significant capabilities in anti-submarine warfare (ASW) and anti-surface warfare (ASuW), enabling it to defend itself and other naval assets. The advanced sonar suite allows for long-range detection and tracking of both surface and subsurface threats. While the Borei II is not primarily an anti-ship platform, its torpedo armament provides a self-defense capability against surface combatants. The vessel is designed for extended deployments, capable of operating in remote areas of the world's oceans.

The sensor suite is a critical component of the Borei II's effectiveness. The MGK-600B Amfora sonar system, with its hull array, towed array, and flank array, provides comprehensive situational awareness, enabling long-range detection of potential adversaries. The installation of the Brick Pulp [MRP-21 Zaliv-P] radar provides surface search and navigation capabilities. Snoop Tray 2 [MRK-50 Kaskad] likely functions as an electronic warfare support measures (ESM) system, providing early warning of radar emissions. The Mouse Roar [MG-519 Arfa-M] is a hydroacoustic warfare system, used for detecting and classifying underwater targets based on their acoustic signatures. The MG-114 Berilly fire control system integrates the submarine's torpedo and missile armament, allowing for effective engagement of both surface and subsurface targets. Generic Submarine Periscope (Optical and LLTV) provides visual situational awareness.
