Description: The Project 667B (Delta Class NATO designation) is the second generation of Project 667A (Yankee Class NATO designation) strategic submarines of which 34 units were produced with the first boat entering service in 1967. Their nuclear propulsion provides outstanding performance over conventionally-powered submarines as well as longer endurance while submerged. The first Project 667B boat was commissioned in 1973 and since then 43 boats were commissioned for the Russian/Soviet Navy.

The Project 667BDRM, Delfin Russian nickname and Delta IV NATO-designation, class nuclear-powered submarines are the last member of the successful Project 667 family started in the 1960s. They were designed to perform strategic deterrence patrols carrying 16 RSM-54 ballistic missiles with 4 nuclear warheads each. Four 533mm torpedo tubes have been provided for ship self-defense launching torpedoes and missiles.

The first Delfin-class submarine entered service with the Soviet Navy in 1985. A total of 7 Delfin-class submarines were procure between 1985 and 1992. These submarines will remain in service well into the 21st century depending upon successor availability. They are the quietest strategic submarines currently in service with the Russian Navy and six boats remain in service as of January 2004.
