The Albacore is a post World War II experimental submarine now on display in Portsmouth NH. Seeing the sub on land, some height above sea level, is a bit surprising, and it’s clear that moving it there was no small task.
Five dollars will get you inside the sub’s tight and awkward quarters, where you’ll see the Frankensteinian bathroom (and that’s for officers) and details such as lithium hydroxide canisters and signal ejector instructions that stand as reminders of the dangers of submarining. Still, it’s open enough that you can sit down at the controls and pretend to pilot the craft.
