The Borei class, alternate transliteration Borey, Russian designation Project 955 Borei and Project 955A Borei-A (Russian: Борей, lit.'Boreas', NATO reporting name Dolgorukiy), are a series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy. The class has been replacing the steadily retiring Russian Navy Delta III and Delta IV classes and fully retired (as of February 2023) Typhoon, all three classes being Soviet-era submarines.

Despite being a replacement for many types of SSBNs, Borei-class submarines are much smaller than those of the Typhoon class in both displacement[8] and crew (24000 tons submerged opposed to 48000 tons and 107 personnel as opposed to 160 for the Typhoons). In terms of class, they are more accurately a follow-on for the Delta IV-class SSBNs.
