USS CUBERA (SS-347) was the first of 24 post-war "GUPPY-II" - converted fleet attack submarines of the Balao class. GUPPY comes from the FRAM* submarine classification "greater underwater propulsive power".
Characterized by a thicker and stronger hull, more powerful electrics, higher fuel and battery capacity than the famous Gato class WWII fleet submarine, Balao class boats like CUBERA became test subjects for pre-nuclear submarine technology development.
In the search for greater speed, stealth and range, many devices invented before and during WWII by the Germans, Dutch and British like the "snorkel" and SONAR, were perfected by the U.S. Navy and found their way into these boats.

* Fleet Rehabilitation and Modernization - a joint military/congressional commission formed after WWII to evaluate needs of the modern Navy in the cold-war scenario. There were some 50 GUPPY boats in all, in several versions, some boats being converted several times. Many boats got snorkels only and were sold to foreign allies for cash to support U.S. conversions.
