On March 19th construction for new Project 885M Yasen-class attack submarine has begun. Arkhangelsk will be the fifth sub of Yasen-class in Russian navy. Yasen is the fourth generation of multipurpose nuclear-powered
submarine equipped with the Oniks and Kalibr type missiles. Yasen-class boats do not have a double-hull. It incorporates a hybrid design with a lighter
structure over the vessel’s pressure hull. What is more the vessel is equipped with a
spherical bow sonar called the Irtysh-Amfora for the first time. As a
result, Severodvinsk and the rest have their torpedo tubes located at about mid-ship
like U.S. submarines. The vessel has eight torpedo tubes, four of which
are 650mm tubes while the rest are 533mm tubes. The Yasen-class
submarines may carry up to 30 torpedoes.
