The four Delta II (Project 667BD Murena-M) nuclear-powered ballistic missile submarines followed the earlier Delta I-class as something of an interim design. The boats were largely similar to the Delta I but had their hulls lengthened by 52.5 feet to accommodate an additional four missile tubes and increased their operating crew from 120 to 130 personnel. Displacement increased to 9,350 tons surfaced and 10,500 submerged. Dimensions included a running length of 508.5 feet, a beam of 39.3 feet, and a draught of 29.5 feet. Performance was slightly reduced when compared to the Delta I boats - surfaced speeds remained 12 knots but submerged speeds were 24 knots at most (from 25 knots). Diving depth improved from 390 meters to 450 meters and output power from the nuclear propulsion / steam machinery was raised to 55,000 horsepower from 52,000 horsepower.

Delta II boats were armed through 16 x D-9D launch tubes for the R-29D ballistic missile series. It retained the 4 x 533mm (21") forward-facing torpedo tubes at the bow and added 2 x 400mm torpedo tubes. Beyond the obvious physical changes to the series, Delta II submarines also introduced several noise-reducing features to help its presented acoustic levels - chiefly shock-absorbing struts at the steam turbines and a hydroacoustic coating on the hull.

Delta II boats were built at Severodvinsk from 1972 to 1975 and were themselves superseded by the newer Delta III-class in time. Decommissioning of Delta II-class boats began in 1996.
