Russia’s Nuclear Missile Carrying Submarine Dmitry Donskoi To Get Advanced Steam Turbine Plant

The new, nuclear-powered, missile-carrying, Project 955A (Borei-A) submarine Dmitry Donskoi will be presented with an upgraded and more advanced steam turbine plant to significantly lower the acoustic signature, a source associated with the domestic defence industry informed TASS on Wednesday at the International Maritime Defense Show 2023.

Dmitry Donskoi will differ from earlier Borei-class subs by several technical improvements launched by the Rubin Central Design Bureau of Marine Engineering that had developed Project 955A. Specifically, innovations will be launched into the steam turbine plant to make the sub’s propulsion unit even quieter, the source added.

He explained that this new vessel is expected to be similar to the upgraded Project 885M (the Yasen-M) multipurpose submarines in terms of the acoustic signature.

TASS does not yet have an official confirmation of the information.

The new, upgraded Project 955A nuclear-powered submarine cruiser, Dmitry Donskoi, was reportedly laid down at Russia’s Sevmash Shipyard in the country’s northwest on August 23 2021. The deal for its construction was signed a year before that, in 2020. The submarine cruiser will likely be operational in Russia’s Northern Fleet and will be delivered to the Navy by late 2026.

TASS reported on Wednesday that the brand-new nuclear-powered sub is expected to be afloat in 2025.
