Eleven Project 949A Antey submarines were completed at Severodvinsk, of which five were assigned to the Soviet Northern Fleet. At one stage it had been planned to develop a new fourth-generation follow-on to the Project 949A, but this plan was later dropped. The external differences between the two classes were that the 949A class is about longer than its predecessor (approximately rather than ), providing space and buoyancy for improved electronics and quieter propulsion.
