B-413 Submarine
The B-413 submarine is a project 641 diesel-electric submarine moored at the World Ocean Museum quay in Kaliningrad, Russia. Measuring roughly 91 meters (299 feet) in length and around 8.5 meters (28 feet) in width, it contains several compartments including torpedo rooms, engine rooms, a control room, and crew quarters.
The submarine was built during the Soviet era and served actively in the Soviet Navy for many years, primarily during the Cold War. After its service ended, it was preserved as a museum piece, documenting the development of Soviet submarine technology over several decades.
The name B-413 follows the Soviet tradition of designating submarines with a letter and a number, reflecting their function and order in fleet service. Onboard, the narrow spaces show how the crew lived and worked in this confined environment, highlighting the discipline and teamwork required by sailors.
The submarine is accessible directly from the museum quay, and visitors can explore the different compartments by walking through narrow ladders and passageways. The tight spaces require care when moving around and may be difficult for people with limited mobility to enter.
Visitors can look through a periscope and view the surroundings from the perspective of a submarine captain, providing an unusual sense of how officers observed their environment while submerged. The sonar room still contains the original equipment used to detect objects and other vessels underwater.
