Independence Seaport Museum – USS Becuna (Philadelphia, Pennsylvania, USA)

USS Becuna

After exploring the exhibits of the Independence Seaport Museum, Jandy and I went out to the waterfront and boarded the World War II/Cold War submarine USS Becuna, anchored next to Admiral George Dewey‘s flagship the USS Olympia, to check the innards of the submarine, a first for both of us, and get a glimpse of all aspects of a submariner’s life.

Both boats are very good static displays and kept in pretty good condition. The USS Becuna (SS/AGSS-319), a Balao-class diesel-electric submarine of the United States Navy nicknamed “Becky,” was named for the becuna, a pike-like fish of Europe.

Exploring the full length of the sub, from stem to stern, requires going into tight spaces (the small hatches, requiring a degree of flexibility, could be tough to maneuver through) and using ladders and steps, so it not a good attraction for those needing accessibility as well as those who are extremely claustrophobic.

You can rush through the tour in only a few minutes but, if you take the time, you can spend the time looking at all of the pipes wires and valves and really feel what it was like to live and work in the extremely tight quarters on this sub.

The Captain’s stateroom was tiny. We weren’t able to see the conning tower and periscopes as it’s only included in the highly recommended “Behind the Scenes” tour which we were too late for.
