Becuna

Becuna, a World War II-era submarine, launched into service in January 1944, just nine months after construction started. “Becky” has called Philadelphia home since 1969. She was moved to Penn’s Landing and opened as a museum in 1976 as a part of the bicentennial celebration of the signing of the Declaration of Independence. She’s been docked alongside Olympia ever since.

CLIMB aboard

You’ve heard of immersive experiences, but have you heard of sub-mersive experiences? Don’t pass on the opportunity to tour a real-life submarine! After descending from Becuna’s top deck, you will find yourself in the Forward Torpedo Room, where the journey begins. While climbing through, with your tour guide’s help, visitors will learn about everything from crew life to the science and technology that make a submarine work! See where they slept (honestly, wherever they could fit bunks), where they showered (although not frequently…that space was reserved for more important things, like storing potatoes!), and where they played countless rounds of checkers and backgammon (be sure to ask your tour guide about the crew’s favorite movie aboard).

While she might seem small compared to her dockmate Olympia (she’s not small; she’s stealthy, we swear), Becuna’s service history is no less impressive. During her 25 years of service, the submarine fought in the Pacific during World War II, acted as a training vessel for the submarine school in New London, Connecticut, assisted in ice research above the Arctic Circle, and was part of the GUPPY modernization program (the only GUPPY 1-A submarine left in the world, we’d have you know!).

How to access Becuna

Guided tours of Becuna are included in the Admiral Dewey, Explorer, and Climb Aboard packages. Please note that due to physical demands, participants must be at least three (3) years of age to participate in the tour.
