The Knyaz Oleg is a Borei-class (Project 955A) nuclear-powered ballistic missile submarine developed by the Rubin Design Bureau and constructed by the Sevmash for the Russian Navy. She was officially launched from its shipyard on 16 July 2020. 

The Borei class, Russian designation Project 955 Borei and Project 955A Borei-A are a series of nuclear-powered ballistic missile submarines being constructed by Sevmash for the Russian Navy.

The Borei submarine is approximately 170 meters (560 ft) long, 13 meters (43 ft) in diameter, and has a maximum submerged speed of at least 46 kilometers per hour (25 knots).

Borei-A submarine is equipped with improved communication and detection systems, improved acoustic signature, and has major structural changes such as the addition of all moving rudders and vertical endplates to the hydroplanes for higher maneuverability, and a different sail geometry.

This submarine is also equipped with hydraulic jets and improved screws that allow them to sail at nearly 30 knots while submerged with minimal noise. According to a Russian report, the Borei-A is able to carry 20 Bulava SLBM and is armed with 16 SLBMs with 6-10 nuclear warheads atop each, just like the Borei submarines.
