The launch of Project 636.3 diesel-electric submarines Mozhaisk and Yakutsk for the Russian Pacific Fleet is scheduled for 2023 and 2024, the Defense Ministry’s Krasnaya Zvezda newspaper reported on Monday.
“The Admiralty shipbuilders continue the construction of submarines for the Pacific Fleet and are currently preparing for joining block modules on the fifth submarine Mozhaisk. Work is underway on the sixth Yakutsk submarine of the Pacific series to shape hull structures. Their float-outs are scheduled for 2023 and 2024, correspondingly,” the newspaper said.
A series of six Project 636.3 conventional subs for the Russian Pacific Fleet is under construction at the Admiralty Shipyard in St. Petersburg in Russia’s northwest. Project 636.3 diesel-electric subs have been developed by the Rubin Central Design Bureau of Marine Engineering. A contract for the construction of six submarines for the Russian Pacific Fleet was signed in September 2016.
The first submarine Petropavlovsk-Kamchatsky was delivered to the Fleet in December 2019 while the second sub entered service on October 24, 2020. The third submarine Magadan was transferred to the Russian Navy in October 2021 and the fourth submarine Ufa was floated out in late March this year.
Project 636.3 Varshavyanka-class submarines (NATO reporting name: Improved Kilo-II) belong to the third generation of large diesel-electric underwater cruisers. They are 74 meters long and displace more than 3,900 tonnes. Due to their strong hull, the submarines have an operational depth of 240 meters and can dive to a maximum depth of 300 meters.
The submarines of this Project have an operational range of up to 7,500 miles. They are armed with Kalibr-PL cruise missiles that are launched from torpedo tubes from the sub’s submerged position.
Project 636 submarines are considered among the world’s quietest underwater cruisers. They can develop a speed of up to 20 knots, have a sea endurance of 45 days, and have a crew of 52.
