Visited the museum during son's welcome home. Bless you, Groton and U.S.A., for this great museum. More

This museum has interesting exhibitions on the submarines of the US Navy. You can also visit parts of a nuclear submarine. It is an impressive show of force, and provides some insights into what living in a sub must be like. I found it interesting for both adults and kids, though the latter found the movie a bit too long. More

They have numerous mock-ups, like the carrier deck, periscope and other nautical memorabilia and most of it is hands-on. They have the first nuclear submarine The Nautilus open for tours. Tours take about an hour or so including a stop at the gift shop. Gotta have pictures of the subs. More

A very interesting free museum that gives a pretty good history of submarines and especially our navy subs through the years. Well organized and intresting---great exhibits. The STAR OF THE SHOW however is the first atomic sub Nautilus which is docked right outside the museum and is available to tour. The people here are helpful and the tour is great.... More

If you have any interest in submarines, this is THE museum to visit and it's FREE. The museum provides the rare opportunity to tour a submarine (the USS Nautilus) and offers engaging visual displays covering the history of submarines and those who have served on them. More

This was a great museum, really enjoyed all that it had to offer. A lot of history there, very informative More

We were disappointed because the Nautilus submarine was closed for cleaning & maintenance but decided to visit the museum anyway. Am I glad we did. The museum was extremely informative and well organized. We spent a couple of hours perusing the exhibits and on top of that it was free (donations accepted)! More

Located just outside of Sub Base main gate so entry was hassle-free. Good selection of minature subs and of course, the Nautilus, which is a free guided tour of the first U.S nuclear submarine. Inside the museum was packed with examples and history of the submarine force. There was also a souvenier store. Highly recommended for submarine buff or tourist... More
