K-571 Krasnoyarsk is a Yasen-classnuclear-poweredcruise missile submarine of the Russian Navy. It is the third boat of the project Yasen-M. Considerable changes were made to the initial Yasen design.[5] Differences in the project have appeared sufficient to consider it as a new upgraded version Yasen-M (Russian: Ясень-М).[6] The submarine is named after the city of Krasnoyarsk.
Compared to the first-of-class Severodvinsk, Kazan, Novosibirsk and Krasnoyarsk are some 40 feet (12 m) shorter, resulting in the deletion of a sonar array from the former's bow. According to one naval analyst, the intention was likely to reduce construction costs without meaningfully reducing the submarine's capabilities. Krasnoyarsk will also include a nuclear reactor with a newly designed cooling system.[7]
On 30 July 2021, Krasnoyarsk was rolled out of the construction hall and subsequently launched on the water.[8] The submarine's future commander Captain 2nd Rank Ivan Artyushin traditionally smashed a bottle against the ship's board. In February 2022, Krasnoyarsk started the mooring trials.[9] Sea trials started on 26 June.[10] The submarine was expected to be commissioned in 2023. She reportedly launched cruise missiles during state tests in November 2023.[11] She was entered service on 11 December 2023.[12]
