USS Cavalla - SS-244

Interntational Call Sign: November-Bravo-Papa-Sierra 

The USS Cavalla is berthed in Seawolf Park, Galveston, Texas as a memorial to the lost submarine USS Seawolf. Cavalla was a Gato class fleet sub, designed and built in the summer of 1943 by the Electric Boat Company and launched on November 14, 1943. She was commissioned on Feb. 29, 1944, the first “leap year” boat built by E.B. On June 19, 1944, on her maiden patrol, she sank the 30,000 ton aircraft carrier Shokaku (veteran of Pearl Harbor and Battle of Coral Sea). This earned her the Presidential Unit Citation.

​After the war, the Cavalla was decommissioned in 1946. She was brought back to service in 1951 and assigned to the Submarine Squadron 10 in New London, Conn. To meet the Cold War Soviet threat, she underwent conversion in 1952 to a new class of American sub–the SSK (hunter/killer).

​On January 21, 1971, the U.S. Navy transferred possession of Cavalla to the Texas Submarine Veterans of WWII. The Cavalla was then delivered to her permanent
berth in Seawolf Park. Gulf coast locals usually refer to the Cavalla as the “Seawolf”, mistaking the name of the memorial park for that of the submarine on exhibit there.
Next to her is the USS Stewart DE-238.

Cavalla is currently enjoying a renaissance; volunteer efforts are at a 10-year high, the local press has covered her history and renovation, and efforts are underway to
bring her back to the proud state her crews through her history have maintained.
