Hi, I’m Irving Greisman. Welcome aboard.

In 1969 I earned my dolphins, the badge of a qualified submariner, aboard USS Tusk, a diesel boat and close cousin of the World War II submarines on this site.

Today I give tours aboard a World War II submarine, and visitors ask the same questions every day. How did they sleep? How was the food? This site is where fellow docent Dwight Naset and I answer them. Dwight also wrote the glossary, so when a term like stern plane stops you cold, he’s got you covered.

Start with a few short answers, or go deep, from batteries and torpedoes to what the cooks served at midnight. Eternal Patrol honors the boats and crews that never came home.

And when you’re ready for the real thing, our museum guide will point you to the nearest boat. Nothing beats squeezing through a hatch yourself.

Didn’t find your question? Send it to us.

Thanks for coming aboard. Let’s go below.

The Museum Boats and Their Stewards

Fourteen WWII fleet submarines are open to the public as museum ships across the United States, from Pampanito in San Francisco to Cod in Cleveland, Bowfin in Pearl Harbor, and Silversides in Muskegon. Each is preserved and restored by a museum or nonprofit that raises the money and does the work. This site draws on all of them as subject matter. See the full list on our Museums page.

This site is independent. It is not affiliated with or endorsed by any of these organizations. The content here is our own work, credited where it comes from elsewhere.

Special Recognition: To all the brave submariners who served with courage and dedication, and to the institutions that preserve their legacy for future generations.

Why No Reference to Women in Your FAQs?

We have been asked why women are not mentioned in our FAQs, and this is a fair question.

The answer is that women did not serve on United States submarines until 2011. Other navies integrated women earlier, including Norway in the mid-1980s, followed by Australia, Canada, Spain, and others in the 1990s and 2000s.

The United States was slower to do so primarily because of berthing and privacy constraints on older submarine designs.
