🕑 Added 2025-01-11 13:18:03 +0000 UTCThe Borei-class SSBN (Russian designation: Project 955 Borei, NATO reporting name: Dolgorukiy-class) is a class of nuclear-powered ballistic missile submarines (SSBNs) operated by the Russian Navy. These submarines are a key component of Russia's nuclear deterrent, replacing aging Delta IV and Typhoon-class SSBNs. Here’s a detailed overview:
General Characteristics:
Role: Strategic nuclear deterrence (SSBN).
Builders: Sevmash Shipyard, Severodvinsk, Russia.
Entered Service: First unit commissioned in 2013.
Active Units (as of 2023): 6 Borei-class submarines, with additional under construction or planned.
Technical Specifications:
Displacement:
Surfaced: ~14,700 tons.
Submerged: ~24,000 tons.
Dimensions:
Length: ~170 meters.
Beam: ~13 meters.
Draft: ~10 meters.
Propulsion:
Single OK-650B pressurized water nuclear reactor.
Steam turbines driving a single shaft and pump-jet propulsor.
Speed: ~15 knots (surfaced), ~29 knots (submerged).
Unlimited range (nuclear-powered), with a service life of ~30 years.
Crew: ~107 (officers and enlisted personnel).
Armament:
Primary Weapon System:
16 Bulava (RSM-56) submarine-launched ballistic missiles (SLBMs):
MIRV-capable (Multiple Independently Targetable Reentry Vehicles).
Range: ~8,000-10,000 km.
Warheads: Up to 6-10 warheads per missile (yield ~150 kilotons each).
Secondary Weapons:
Torpedoes: 533 mm torpedo tubes.
Cruise missiles: Can carry Kalibr or P-800 Oniks missiles for conventional roles.
Countermeasures:
Decoys and advanced sonar evasion systems.
Modernized combat management and electronic warfare systems.
Design Features:
Stealth:
Advanced sound-isolation technologies.
Coated with anechoic tiles to reduce sonar signature.
Quiet pump-jet propulsion system.
Structure:
Double-hull design for increased survivability.
Divided into multiple watertight compartments.
Modern Sensors:
Advanced sonar, navigation, and fire control systems.
Automated systems reduce crew workload.
Notable Units:
K-535 Yuri Dolgorukiy (First of class, commissioned in 2013).
Other units include Alexander Nevsky, Vladimir Monomakh, and additional Borei-A variants (an improved version of the Borei design).
Strategic Role:
The Borei-class serves as a critical part of Russia's nuclear triad, ensuring second-strike capability. Its Bulava SLBM system provides a credible nuclear deterrent with the ability to penetrate modern missile defenses. The Borei-class is stationed with the Northern Fleet and Pacific Fleet, ensuring global coverage.
