On March 27–28, Russian President Vladimir Putin made rare and high-profile visits to two Yasen-M class nuclear-powered attack submarines—*Arkhangelsk* and *Perm*. The visits signal a renewed focus on Russia’s most advanced submarines amid ongoing naval challenges in the Black Sea. In this video, we explore why the Yasen-M class holds such strategic significance for the Russian Navy. From its massive displacement and advanced sonar systems to its unmatched multi-mission capabilities, the Yasen-M is often seen as Russia’s answer to the U.S. Navy’s Seawolf-class. We also look at how Russia’s geography, declining surface fleet, and reliance on submarines shape its naval doctrine—and why Putin is doubling down on underwater power projection.
