Traveled the Seas for Service
Becuna returned to the United States in 1949 where she was reassigned from the submarine base at Pearl Harbor, Hawaii to the one located in New London, Connecticut. In 1951 she underwent modernization as part of the United States Navy’s Greater Underwater Propulsion & Power Program, otherwise referred to as the GUPPY Program. Becuna was refitted with a Guppy 1A modification that included a streamlined hull, a hydrodynamic fairwater or “sail,” upgraded batteries, and a snorkel system. Becuna is the only Guppy 1-A type submarine remaining anywhere in the world.
During the Cold War, Becuna was primarily a training vessel, station at the submarine school in New London, Connecticut. There she taught the next generation of submariners how to go to sea by completing training cruises and participating in NATO exercises. Becuna’s service also took her to the Arctic Circle, the Mediterranean, and more where she conducted surveillance assignments against the Soviet Union, taking photographs of radar installations through per periscope and recording the sonar signature of Soviet submarines.

Historic ships collections
Along with Cruiser Olympia and Submarine Becuna, the Seaport Museum also maintains a vast collection of historical artifacts and records relating to both vessels. The Cruiser Olympia Collection has been inventoried and a collections guide can be found on theOnline Catalog page of the website.
The Submarine Becuna collection, which is not currently processed, dates from the 1940s until the 1960s. The collection is essentially divided into two parts: the submarine’s plans and mechanical operations, and the personal accounts and artifacts of those that served aboard her. Accounts and artifacts include correspondence, scrapbooks, photographs, oral histories, biographies and ephemera, like menus, ration cards, invitations, and programs, relating to submariner’s time on Submarine Becuna.
