According to an industry source, quoted in the Russian media, the 2018-2027 State Armament Program includes construction of two additional Project 955A/Borey-A submarines. This will bring the number of submarines of the Project 955 class to ten by 2028. The source said that five submarines will be based in the Northern Fleet and five - in the Pacific. He also suggested that the construction of the Borey submarines will continue after 2027, since it is unlikely that the Project 667BDRM subs will be able to remain in service that long. (Back in May 2018, it was suggested that Russia may build six additional Project 955A submarines, bringing the total to 14.)

The original plan called for construction of eight submarines of the Project 955 class. Three of them are already in service - Yuri Dolgorukiy with the Northern Fleet and Alexander Nevskiy and Vladimir Monomakh in the Pacific. The fourth submarine, Knyaz Vladimir, just began sea trials (it left the dry dock in November 2017). Construction of the eighth submarine, Knyaz Pozharskiy, began in December 2016.
