The Becuna is a Balao class American Diesel - Electric submarine that was  commissioned in May, 1944. In WWII it served as submarine flagship of the Southwest Pacific Fleet and it sunk enemy vessels in the Philippines and South China seas. In 1951 the boat was upgraded to a Guppy 1A (Greater Underwater Propulsion Power) type of boat and a Snorkel air system was installed. After the revamp, the Becuna served during the Korean and Vietnam wars. The Becuna retired in 1969 and is now part of the exhibition of the Independence Seaport Museum in Philadelphia (PA) USA.
