USS Cubera SS347

• Namesake: USS Cubera (SS-347) was named after the cubera, a large species of snapper fish found in the western Atlantic Ocean. • Class and Construction: She was a Balao-class submarine, one of the most successful and numerous US submarine classes of World War II, built at the Electric Boat Company in Groton, Connecticut. • Launch and Commissioning: The submarine was launched on June 17, 1945, and commissioned on December 19, 1945, just after the end of World War II, so she did not see wartime action. • Postwar Role: USS Cubera served primarily in the Atlantic Fleet, engaged in training exercises, anti-submarine warfare (ASW) drills, and fleet maneuvers during the early Cold War period. • GUPPY II Modernization: In 1947, she underwent extensive modifications under the GUPPY II (Greater Underwater Propulsion Power Program) conversion, which improved her underwater speed, endurance, and habitability, adding a snorkel and new battery systems. • Home Port: Her home port was Key West, Florida, a hub for Atlantic submarine operations and training during the postwar years. • Rescue Operations: In 1947, Cubera participated in the rescue and salvage operations after the explosion of the USS Cochino (SS-345) in the Barents Sea, demonstrating the dangers of Cold War submarine operations. • Cuban Missile Crisis: During the Cuban Missile Crisis in October 1962, USS Cubera was placed on alert and played a role in US naval readiness during this tense period. • Transfer to Venezuela: On May 1, 1972, Cubera was decommissioned and transferred to the Venezuelan Navy, where she served as ARV Tiburon (S-12) until 1989. • Legacy: USS Cubera earned a Navy Unit Commendation and contributed to the evolution of submarine tactics and technology during her nearly three decades of service in two navies.
