| History | USS Becuna conducted five wartime patrols with the U.S. Seventh Fleet. Becuna sank the 7500 ton freighter Nichiyoku Maru, two small coastal freighters, assisted USS Hawkbill with the sinking of the oiler Tokuwa Maru, and damaged another oiler. The submarine also served as a lifeguard for downed pilots and narrowly missed an attack on the battleship Yamato. Converted from her basic fleet boat configuration to a streamlined fast underwater submarine known as a GUPPY (Greater Underwater Propulsion Project) type 1A in 1951, Becuna served during the Korean War and Vietnam conflict in the Atlantic and Mediterranean. Berthed at Penn's Landing in Philadelphia, the boat now serves as an educational resource and tourist attraction with the cruiser Olympia. USS Becuna is a National Historic Landmark. |
