Project 885 Yasen is a class of Russian nuclear-powered multipurpose attack submarines. Project 885 Yasen design is a derivative of the Project 971 Akula. The original idea was a design with a multi-task profile, allowing to change the profile of weapons loaded to adjust to several missions. It features a significant cruise missile capability with eight vertical launch tubes for cruise missiles aft of the sail.
In total 12 Project 885 Yasen submarines were planned for the Russian Navy. The first of them, K-329 Severodvinsk, entered in service with the Russian Northern Fleet in September 2011. Four more advanced Yasen-M-class submarines are set to be delivered by 2016.
