K-553 Generalissimus Suvorov, the sixth submarine of the Project 955 line and the third Project 955A/Borey-A submarine, was officially accepted for service on 29 December 2022. The submarine will join Alexander Nevskiy and Vladimir Monomakh in the Pacific.

Construction of Generalissimus Suvorov began in December 2014. It was launched in December 2021 and began sea trials in July 2022. In November 2022 the submarine performed a successful launch of a Bulava SLBM.

On the same day, the seventh Project 955 submarine, Imperator Alexander III, was launched into water. The construction of strategic submarines is behind schedule. Generalissimus Suvorov and Imperator Alexander III were expected to enter service in 2020.

Tree more submarines of this line are under construction. Knyaz Pozharsky was laid down in December 2016. That is the last submarine built under the original 2012 plan that called for construction of eight Borey/Borey-A submarines. The idea of continuing the production of Borey/Borey-A was discussed at various points of time - the total of ten in 2012, the total of 14. Later in 2018 the decision was made to build two more, bringing the total to ten. The contract with OSK/Sevmash was signed in July 2020. The submarines, Dmitry Donskoy and Knyaz Potemkin, were laid down at Sevamash in August 2021.

UPDATE: The submarine will eventually join the Pacific Fleet.
