Russian submarine Knyaz Oleg

The submarine was laid down on 27 July 2014.[3] In February 2018 it was reported that the construction of the submarine had been delayed because the builder, Sevmash, had not received a diesel generator for the submarine. According to Sevmash the problem was with its supplier Kolomensky Zavod, which had not been able to deliver the part.[4]

It was launched from its shipyard on 16 July 2020.[2] She was reported on sea trials as of April 2021.[5] While it was initially anticipated that the submarine would serve in the Pacific Fleet after commissioning, in May 2021 it was reported that consideration was being given to potentially transferring some of the Borei-class boats originally intended for the Pacific Fleet to the Northern Fleet instead. As of 2021, it was therefore unclear whether Knyaz Oleg would ultimately deploy with the Pacific or the Northern Fleet. [6]

On 21 October 2021, Knyaz Oleg launched one missile from submerged position in the White Sea. Warheads successfully hit targets at the Kura Missile Test Range in Kamchatka.[7]

On 21 December 2021, Knyaz Oleg was commissioned along with Novosibirsk into the Pacific Fleet. Russian President Vladimir Putin attended the ceremony via a video call.[8]
