On 24 July 2025, K-555 Knyaz Pozharsky, a submarine of the Borey-A/Project 955A class, was transferred to the Russian navy in a ceremony at Severodvinsk.

The construction of the submarine began in 2016. Its acceptance for service was expected in late 2024, but was postponed, initially to June 2025, reportedly to complete the state trials that normally include a missile launch. However, there have been no indications that Knyaz Pozharsky conducted a Bulava launch.
