Submarine B-413

  Submarine B-413 is positioned along the Pregolya River in Kaliningrad, close to the iconic Museum of the World Ocean. Commissioned in 1963, this diesel-electric submarine once served in the Soviet Navy, patrolling the Black Sea and later the Pacific Ocean. Today, it functions as a floating museum, allowing visitors to explore its interior and learn about life aboard a submarine during the Cold War. Open year-round, the best time to visit is during the warmer months, from May to September, when the weather facilitates easy access to the site. Inside, guests can observe the submarine’s operational equipment, crew quarters, and historic artifacts, gaining a firsthand glimpse into this unique military vessel.
