Russia’s Pacific Fleet will receive six new Project 636.3 Kilo-class (aka Vashavyanka-class) diesel-electric attack submarines by 2021. “The term of delivery of the six boats [is] two in 2019, two in 2020 and two in 2021,” the head of Admiralty Shipyard, Alexander Buzakov told TASS news agency on September 7.
The Project 636.3 Kilo-class is an improved variant of the original Project 877 Kilo-class design. The updated version is slightly longer in length — the sub’s submerged displacement is around 4,000 tons — and feature improved engines, an improved combat system, as well as new noise reduction technology. The submarine has a crew of around 50 and can conduct patrols for up to 45 days. The improved Kilo-class can fire both torpedoes and cruise missiles, launched from one of six 533 millimeter torpedo tubes.
