Take a deep dive into the fascinating world of submarines at the Royal Navy Submarine Museum.

Discover HMS Alliance, the only remaining Second World War era submarine. Explore the decks and narrow corridors, look through the original periscope, and hear the stories of those who served onboard.

As well as HMS Alliance, you can explore the other submarines including Holland I and X24 as well as photographs, documents, ship plans, and artefacts from another time.

Don’t forget to go to our Silent and Secret exhibition which follows the Royal Navy's at sea nuclear deterrent, telling the story of those who served under water for months at a time. See objects that retell hidden conflicts and first-hand accounts from crew onboard.

Original Royal Navy Jolly Roger flag from HMS E45

See Beneath the Surface

Did you know that Royal Navy submarines used to fly Jolly Roger flags? This cheeky tradition started over a hundred years ago in response to one Admiral comparing submariners to "pirates". 

Lieutenant Commander Max Horton embraced the comparison and flew the first Royal Navy Jolly Roger as he returned from sinking a German warship in 1914. From this act submariners began handmaking their own flags, each one telling the unique story of the submarine on which they served. 

You can see the earliest surviving Royal Navy Jolly Roger, and learn more about their incredible history, only at the Royal Navy Submarine Museum.

You can access our museum by car and if using a satnav device, please use the address: Haslar Road, Gosport PO12 2AS

Polite notice: Whilst the postcode is correct, satnavs may direct you to the centre of the naval base. Please follow tourism signs for the Submarine Museum once you've entered Gosport


A Waterbus from the Historic Dockyard runs regularly to the museum. 

The waterbus operates between 10am to 4pm daily during Summer, unless weather or other operational restrictions apply. During Winter, the waterbus operates under a restricted service, weekends only and subject to weather or other operational restriction.

The Waterbus is unfortunately unable to accommodate wheelchairs, due to the unsuitability of the jetty and steps. A suitable wheelchair can be pre-arranged to meet the waterbus on arrival in Gosport. Please ask a member of staff for details or email to confirm availability.

Please note that your safety is our number one priority and the sea is subject to change. Due to this, the waterbus may not be running. In the unlikely event the waterbus stops running when visiting one of our Gosport sites from Portsmouth Historic Dockyard, you will need to arrange alternative travel back. This can be on the Gosport Ferry, which is larger than the waterbus so can operate in rougher conditions, or arrange a taxi from a local company. The National Museum of the Royal Navy will not be able to reimburse you for alternative travel arrangements.


You are able to walk between our two Gosport sites. Please note however that this is a 2 mile walk and will take roughly 40 minutes.

We welcome all visitors to the Dockyard and we have tried to make it as safe as possible. However, some of our attractions are historic buildings and ships, and we know that there can be challenges for some visitors.

For those who believe they will be limited in their visit or need extra support we do offer access restriction discounts, free carer tickets and on-site additional support.

The Royal Navy Submarine Museum has a buggy park is available for guests to use. Please note that your buggy and any items left in the buggy are left at your own discretion and we take no responsibility for anything lost or stolen.

Accessible toilets are available to guests at the museum

Free WiFi is available to our visitors. You will need to sign in and agree to terms and conditions.

Guidelines for visitors (2024)

To ensure all visitors to The Royal Navy Submarine Museum have a safe and rewarding experience we have compiled these brief safety notes.

All buildings, historic submarines, and exhibits are assessed regularly and maintained to a high standard, as are equipment and procedures (e.g. fire evacuation). Due to the nature of our attractions, some hazards cannot be avoided but they can be mitigated. They all may have raised sharp edges, electrical hazards, fire hazards, trip/fall/slip hazards and rusty/dusty artefacts. First aid trained staff are available at all sites. Please approach the nearest members of staff if any assistance is required or an emergency occurs.

All Front of house staff are trained in evacuation procedures; in the event of an evacuation alarm, please follow the instructions given by the staff. Do not stop to collect your belongings. Please contact a member of staff should you need assistance.

The General Environment

The Royal Navy Submarine Museum was once part of the HMS Dolphin site and has undergone many changes over the years. Visitors will encounter uneven surfaces across the site made up of a variety of materials including cobbles, decking, tarmac and concrete.

While efforts have been made to make the museum as accessible as possible to all visitors, some areas may present difficulties to visitors who use wheelchairs, have restricted mobility or have visual or hearing impairments.

We recommend you wear sturdy shoes and dress for the outdoors i.e. layers and warm coats.


The National Museum of the Royal Navy is protected by 24-hour CCTV. Visitors are responsible for their own health and safety while visiting our museum and are expected to take reasonable precautions to prevent accidents or injuries.

In the event of an emergency evacuation please follow staff instructions, who are trained to ensure people get out of the museum galleries safely and quickly.

Conservation and Maintenance Work

There is always work happening across all our sites to keep our historic Submarines and buildings safe and well maintained. You may come across areas barriered off during your visit. Please ensure that members of your group do not enter any of these areas.
