USS Becuna (SS/AGSS-319), Balao-luokan sukellusvene, on Yhdysvaltain laivaston entinen alus, joka on nimetty becuna, hauen kaltainen eurooppalainen kala. Hänet nimitettiin kansalliseksi historialliseksi maamerkiksi palveluksestaan toisessa maailmansodassa, josta hän ansaitsi neljä taistelutähteä. Hän palvelee tällä hetkellä museolaivana Independence Seaport Museumissa Philadelphiassa, Pennsylvaniassa.

The Deep-Diving Fleet Submarine
Nniiden USS Becuna on Balao-class submarine, the most successful class of American submarines in World War II. Launched in 1944, the Becuna was a “fleet submarine,” designed to travel with the main battle fleet across the vast Pacific. Unlike the earlier Gato-class, the Balao-class utilized high-tensile steel (HTS), allowing it to dive to depths of 400 feet (120m), significantly safer from Japanese depth charges.

The GUPPY Modernization
- Streamlining the Hull: In 1951, the Becuna underwent a GUPPY IA (Greater Underwater Propulsive Power) conversion. This removed the deck guns and replaced the bulky WWII bridge with a streamlined “sail” to reduce underwater drag.
- Snorkel System: The conversion added a “snorkel” (inspired by German technology), which allowed the submarine to run its diesel engines and recharge batteries while submerged at periscope depth.
- Battery Upgrades: The internal “Sargo” batteries were replaced with much larger, high-capacity battery banks, nearly doubling the boat’s submerged endurance and speed.
- Sonar Evolution: Her radar and sonar systems were upgraded throughout the 1950s and 60s, transitioning her from a surface-running raider to a true underwater Cold War interceptor.
Service and Preservation
- WWII Combat: During her five war patrols, the Becuna was credited with sinking several Japanese merchant ships and tankers, totaling thousands of tons, earning two battle stars.
- Cold War Role: Post-GUPPY, she operated primarily in the Atlantic and Mediterranean, tracking Soviet naval movements and participating in NATO exercises until her decommissioning in 1969.
- Museum Ship: Today, the Becuna is a National Historic Landmark. She is preserved at the Independence Seaport Museum in Philadelphia, Pennsylvania, where she is moored alongside the Spanish-American War cruiser USS Olympia.
