HMS Ocelot

HMS Ocelot is a diesel-electric submarine in Chatham, United Kingdom, now open as a museum. The vessel extends 90 meters (295 feet) and divides into sections for steering, torpedoes, machinery, and crew accommodation.

Chatham Dockyard completed the submarine in 1962 and sent it into the Arctic, Atlantic, Mediterranean, and Baltic during the Cold War. The boat conducted surveillance patrols and remained in service until decommissioning in the early 1990s.

This vessel marks the end of centuries of shipbuilding in Chatham and shows the cramped conditions crews endured for weeks beneath the surface. Visitors today still see the bunks, galley, and washrooms that bring daily life aboard into focus.

Tours through the interior require advance booking and include the command center, torpedo room, and sleeping chambers. Visitors should expect narrow passageways and low ceilings that make the experience physically demanding.

During its first three years the boat traveled more than 166,000 kilometers (90,000 nautical miles) while testing Mark 24 torpedoes. Some of its missions remain classified to this day.
