The USS Becuna is a Balao-class submarine built in 1943 that famously sank 3,888 tons of enemy shipping during World War II, earning four battle stars. Following its wartime service, the submarine was converted in 1951 as part of the Greater Underwater Propulsive Power 1-A modernization. After serving in peacetime missions, including conducting ice research in the Arctic, it was decommissioned in 1969 and eventually became a museum exhibit in Philadelphia. It remains the only GUPPY 1-A submarine left today, showcasing its significant military and historical legacy.
The USS Becuna, unique as the last GUPPY 1-A submarine globally, showcases a significant military legacy from its World War II service to its modern-day preservation.
Built in 1943, this Balao-class submarine not only contributed to the war effort, sinking 3,888 tons of enemy shipping, but has also evolved into a historical exhibit.
The Becuna underwent a GUPPY 1-A modernization in 1951, enhancing its underwater capabilities while allowing it to serve unique roles like ice research missions in the Arctic.
