SubmarineDesigned to deliver missile blows on enemy large military-industrial installations. 
It carries RSM-50 two stage liquid-propellant missiles of the D-9R system, the first sea-based ballistic missiles with MIRVed warheads. The cruiser is similar to the Project 667.BD cruiser, but slightly longer. 
The design has not been changed - it constitutes a doubled-hull submarine with missile silos accommodated in the inner hull. 
The silos guards became higher to match the guards of retractable devices (periscopes, masts, etc.). 
During development of the cruiser, considerable attention was paid to the improved fire-control system. The torpedo tubes are fitted with a rapid-loading system. 
All torpedo tubes are accommodated in the bow section. 
The cruiser is also fitted with a floating antenna buoy to receive radio messages, target designation data and satellite navigation signals at a great depth. 
The bow horizontal hydroplanes are arranged on the sail guard. 
They can rotate to vertical for breaking through ice when surfacing in arctic regions. 
The cruiser is fitted with a gymnasium and solarium to improve habitability.
