B-413 was the last submarine of the Foxtrot class (Project 641) to be retired from the Russian Navy.
The submarine logged over 13,000 nautical miles in undersea operations during its service life.
Unlike many museum ships, the B-413 features almost entirely original mechanical components and interior fittings.
Its hull design was specifically built for long-range patrols, allowing it to remain submerged for extended durations during the Cold War.
The crew consisted of approximately 78 sailors who lived in highly confined spaces for missions lasting several months.
It is the only museum ship in Russia that maintains its original authentic state from the day it left active service.
B-413 is a Foxtrot-class diesel-electric submarine permanently moored as a museum ship at the World Ocean Museum embankment in Kaliningrad. Commissioned in 1968, it served in the Soviet Navy's Northern Fleet before being decommissioned and converted for public access in 2000. It remains one of the few submarines in the world preserved in its original configuration without structural alterations. Visitors move through original hatches and narrow corridors across all seven compartments of the vessel. The interior retains authentic navigational equipment, torpedo tubes, sonar systems, and sleeping quarters used by the crew. It provides an unfiltered look at the claustrophobic conditions and technical complexity of Cold War-era underwater warfare. The submarine is part of the larger World Ocean Museum complex located along the Pregolya River.

Remove bulky backpacks before boarding, as the hatches and internal corridors are extremely narrow.
Wear flat, non-slip footwear to safely navigate the steep, ladder-like vertical hatches.
Visit on a weekday to avoid crowds, as the narrow passageways become difficult to navigate when busy.
Do not attempt to enter if you suffer from severe claustrophobia or limited mobility, as the vessel requires climbing steep vertical ladders.
Closed on Mondays and Tuesdays.
Avoid touching sensitive control panels and navigational equipment; do not block narrow corridors.
