OVERVIEW: The PLARB-667BDRM Delta IV [Delfin] is a Russian nuclear-powered ballistic missile submarine (SSBN) of the Delta IV class, representing a crucial component of Russia's strategic nuclear deterrent. Commissioned in 2015, this vessel incorporates improvements and upgrades over earlier Delta-class submarines.

DETAILS: The Delta IV class, designated Project 667BDRM 'Delfin' by the Russian Navy, represents the fourth generation of Soviet/Russian nuclear-powered ballistic missile submarines. The class was developed in the late 1970s and early 1980s at the Rubin Design Bureau, building upon the preceding Delta III design. Key improvements included enhanced acoustic quieting, a more advanced missile system (the SS-N-23 Skiff), and improved operational capabilities in harsh Arctic environments. The commissioning of PLARB-667BDRM in 2015 suggests either a comprehensive modernization program applied to an older hull or the construction of a new vessel using existing design principles. This emphasis on maintaining a credible sea-based deterrent reflects Russia's strategic doctrine.

The primary role of the PLARB-667BDRM is to provide a secure and survivable platform for launching nuclear-tipped ballistic missiles against strategic targets. While primarily an SSBN, the vessel also possesses capabilities for self-defense against anti-submarine warfare (ASW) threats. The installation of the Shark Gill [MGK-520 Skat-BDRM] sonar suite provides comprehensive underwater situational awareness, including active and passive detection modes for locating enemy submarines and surface vessels. The Shark Tail [Pelmida] towed array sonar further enhances passive detection ranges, particularly in shallow water or noisy environments. The presence of Snoop Tray 2 [MRK-50 Kaskad] radar suggests a limited surface surveillance capability, crucial for navigation and avoiding collisions in surfaced transit.

The PLARB-667BDRM's operational effectiveness is heavily reliant on its sophisticated sensor suite and weaponry. The Brick Pulp [MRP-21 Zaliv-P] electronic warfare support measures (ESM) system allows for the detection and analysis of enemy radar emissions, providing early warning of potential threats. The Mouse Roar [MG-519 Arfa-M] sonar is likely used for mine detection and avoidance. Optical and LLTV submarine periscopes provide visual situational awareness when surfaced or at periscope depth. The SS-N-23 Skiff SLBM constitutes the vessel's primary offensive armament, capable of delivering multiple independently targetable reentry vehicles (MIRVs). Furthermore, the 533mm torpedo tubes provide a means of engaging enemy submarines and surface combatants at shorter ranges. Signal Ejectors are used for communication and decoy deployment.
