The HMS Otus served in the Royal Navy for 28 years before being decommissioned in 1991.
Oberon-class submarines were known for their exceptional silence, making them effective for intelligence-gathering operations.
The submarine is 90 meters long and has a displacement of over 2,000 tons.
Original technical components, including the sonar and radar consoles, are still visible inside the vessel.
The submarine was towed from the UK to Sassnitz to become a permanent museum attraction.
The Erlebniswelt U-Boot features the HMS Otus, a British Oberon-class submarine commissioned in 1963. Moored in the port of Sassnitz on the island of Rügen, it functions as a floating museum dedicated to cold-war naval history. Visitors can walk through the engine rooms, torpedo compartments, and crew quarters to experience the cramped conditions of submarine life. The vessel remains in its original state, preserved to show the technical infrastructure required for underwater navigation. It was acquired and relocated to Germany in the early 2000s after being decommissioned by the Royal Navy. The tour path follows the interior layout of the sub, highlighting both operational equipment and living spaces. Access is provided through the original hatchways, maintaining the authentic spatial experience of the craft.

Wear flat, sturdy shoes as the vessel has steep metal ladders and uneven, narrow floor gratings.
Bring a light jacket, as temperatures inside the hull remain cool even during summer months.
Avoid carrying large backpacks or bulky bags, as the interior passages are extremely restrictive.
Trying to navigate with children in strollers or large camera equipment, which are not permitted inside the submarine.
Operations are generally continuous but may be suspended during extreme storm events or high winds for safety.
Do not touch historical control panels or switches; watch your head on low-hanging piping and hatch frames.
