Royal Navy Submarine Museum

About

Discover the extraordinary life of a submariner first-hand at The Royal Navy Submarine Museum on the Gosport side of Portsmouth Harbour.

Explore the depths of Britain’s only surviving Second World War-era ocean-going submarine, HMS Alliance. See and feel how crew members packed into its small spaces and hear from ex-submariners about how they lived and protected the country in such challenging conditions.

Take a peek at Portsmouth Harbour through Alliance’s working telescopes. Can you keep a secret? Learn about the covert missions of the only surviving midget submarine from the Second World War, X24. Face the enemy and test your tactical awareness in the museum’s interactive gallery, have a go at keeping a submarine buoyant and, for the younger sea-goers out there, treasure may be afoot. Beware of the pirates, recruiting for those longing for sea adventures, on board the pirate ship or yellow submarine in the Busy Boats Bay
