Aboard the USS Cavalla. Serving 1943-1968, this submarine is now a museum and a fascinating look at how people lived on a sub for months at a time. Space was tight – apparently some sailors slept with torpedoes inches above and below them. 😯 #submarine #navy #museum #galveston #history #wwii via Instagram https://instagr.am/p/Cvhgw6guyLQ/
