Awesome museum for everything to do with submarines. It was great to walk through an old diesel sub, plus they have an X-sub and a bit about HMS Dolphin. Staff friendly and helpful. It took about 2 hrs to get round everything, but if you stop to watch all the videos and have a coffee it will take a bit longer. Great visit.

What a great time! What more could a guy want on his 57th birthday! A great history of submariner life and the development of an awesome weapon of war. Some amazing displays and some personal items on show bringing into focus the not so glamorous areas of navel warfare. Once that is finished the best bit was to come, the tour around a real submarine!! The best way to experience this would be to go and investigate yourself as words would be difficult to try and explain and would not do it justice. There have on station veterans who walk you through anything you want to ask, my thanks for their service, BTW. Probably best to leave the kids at home, unless they have a genuine interest, as they could get board very quickly but they would enjoy it non the less, especially going into the sub itself. Well worth the visit and the time and a thank you to the partner for organising - hit that nail squarely on the head for me!

We really enjoy visiting the submarine museum today. Great display of information about the Royal Navy Submarines. My son enjoyed all the interactive stuff there too. I really liked very much all the information about HMS Conqueror specially during the Falkland War. Also the HMS Holland 1 was very impressive.

We visited this as part of our ultimate ticket. 3 boys, 10, 8, 4 and a newborn in a sling. Definately worth getting the guided tour as tells you so much more. We had Mark guide us around and very engaging with the adults and kids and really made the experience. Great insight into what submariners experience and have to go through and need to allow about 2hrs to cover the museum exits as well.

Came over from the Dockyard on the water bus, it’s a popular way to visit so you need to plan your schedule as the boat has limited capacity. The chance to go round the submarine itself is very interesting and something the children enjoyed. The exhibits are very good too.

If you are visiting the Portsmouth area of England, this is one of the Gosport attractions of the Portsmouth Historic Dockyard and this is definitely a one day visit regardless of your interest in military technology. The submarine HMS Alliance is really a 15 minute walk-through tour with no stories since the submariners can't talk about them due to the British Secrecy Act. The museum itself has HMS Holland, the first British submarine, an X-craft and other submarine related stories and info. For enthusiasts, I would recommend staying on the Gosport side of Portsmouth so you can be at this museum when it opens and leave it when it closes since the water bus commutes will cut your time short on both ends. For those somewhat interested, I would recommend staying on the Portsmouth side instead. Pleas keep in mind, however, that the Gosport attractions (and therefore the water bus) are closed on Mondays and Tuesdays, unless there are school holidays in which case they are open.

We visited the museum on a very wet September day. The boat trip from Portsmouth historic dock was only 10 minutes and once there, the submarine was massive and the guide, who’d served aboard submarines for 18 years was very knowledgeable. The museum was packed with items and artifacts. We loved it

Not very big but very interesting! You can see the first British submarine, HMS Holland, but also two submarines from WW II, HMS X24 and HMS Alliance. You can also find out a lot of information about life on board a submarine, how they are made, their missions and much more. Attention, even if you have already bought a ticket that includes all the objectives in Portsmouth Historic Dockyards and the museums in Gosport, to visit the most interesting exhibit HMS Alliance, you must first enter the museum building, at the ticket office, to make an appointment visit (entry is only in small groups, at certain time intervals).
