The strategic missile submarine cruiser of Project 667BDRM is the latest modification in the series of the 2nd generation Russian nuclear missile submarines.

Special features of the Project are:

• one of the most advanced missile weapon complexes as of today
• enhanced stealthiness, survivability and nuclear safety as compared to previous modifications

The project combines both advantages of its predecessors in the 2nd generation of nuclear missile submarines as well as state-of-art science and technology achievements.

The development of nuclear missile submarine Project 667A, the first of the 2nd generation among Russian nuclear missile submarines, began in 1960. The project was designed under the leadership of talented designers, to-be Members of the Russian Academy of Sciences: Chief Designer Sergei N. Kovalev and his first deputy Igor D. Spasskiy. Distinctive features of the Project 667A missile submarine as compared to their predecessors were as follows:

• the intercontinental range of the missile complex
• automated pre-launch missile preparation
• the Integrated Automated Control System
• increased diving depth
• improved habitability conditions

The development of a large series of Project 667A subsurface launch platforms set the framework for the system of strategic naval nuclear weapons as a major factor of strategic deterrence.

Project 667A was developed with account for its upgrading capacity, and at a later stage, several modifications were made (667B, 667BD, 667BDR and 667BDRM). Sequential submarine modifications were mainly due to the introduction of new missile complexes. The total number of boats in this largest series of Russian nuclear missile submarines was 77.

Project 667BDRM nuclear missile submarines perform critical tasks within strategic deterrence. Upgrading of submarine cruisers of this Project ensures high operating and combat characteristics, maintaining the sea component of Russian deterrent force at its high degree of alert.
