Yasen-class submarine
The Yasen class, Russian designations Project 885 Yasen and Project 885M Yasen-M (Russian: Ясень, lit. 'ash tree', NATO reporting name: Severodvinsk), also referred to as the Graney class, are a series of nuclear-powered cruise missile submarines designed by the Malakhit Marine Engineering Bureau and built by Sevmash for the Russian Navy. Design work commenced in earnest in the 1980s with the first submarine built in the 1990s–early 2010s with commissioning in 2013. Two additional boats to an upgraded (and slightly shorter overall) Yasen-M design were commissioned in 2021 and six more are under construction. Based on the Akula class and Alfa class designs, the Yasen class is projected to replace the Russian Navy's current Soviet-era nuclear attack submarines. The Akula class is optimised for a hunter-killer role, whereas the Yasen class concept uses the platform as a nuclear guided missile submarine (SSGN).
