The guided tour shows what life on board a submarine is really like; find out how the emergency escape system works; take a look through the periscopes, see whether you think you could feed the crew from the vessel's small galley.

HM Submarine Ocelot was the last warship built for the Royal Navy at Chatham Dockyard. An 'O' Class diesel electric submarine launched in 1962 and saw service with Royal Navy throughout the height of the Cold War until she paid off in 1991. A normal sized crew would consist of 69 submariners, although she could carry a maximum of 80.

The very best of military music will be on parade for a traditional Beating of the Retreat and Ceremonial Sunset at 6pm.
