By Dave Majumdar, The National Interest: “Russia's second Severodvinsk-class submarine K-561 Kazan , which is a modified Project 08851 Yasen-M design, went to sea for the first time for builder's trials on September 24."
By Ben Werner, USNI News: “The Navy's next class fast attack submarine will be designed for a return to blue-water great power competition, where the ability to support forces ashore is less important than operating in the open ocean hunting rival submarines.”
