USS Cavalla and USS Stewart
In 1971, USS Cavalla (SS-244) was transferred from the US Navy to the US Submarine Veterans of World War II, Texas (SubVets) and towed to its current berth at Seawolf Park. Seawolf Park was named for the submarine and crew of the USS Seawolf (SS-197) which was lost at sea during WWII. Three years later, the USS Stewart (DE-238) joined USS Cavalla to create a unique pair of warfighting vessels - Predator and Protector.Since 1998, the Cavalla Historical Foundation assumed oversight of the Galveston Naval Museum, formerly the American Undersea Warfare Center and its mission to restore, maintain and operate USS Cavalla, USS Stewart, the sail of the USS Tautog (SSN-639) and the conning tower of the USS Carp (SS-338). The American Undersea Warfare Center became know as the Galveston Naval Museum in 2018.
The USS Cavalla is best know as the "Avenger of Pearl Harbor" sinking the Japanese Aircraft Carrier, Shokaku, a veteran of the Pearl Harbor attack. This action earned the Cavalla the prestigious Presidential Unit Citation.
The Cavalla has been in Galveston for almost 50 years, serving as a museum ship on Seawolf Park since 1971. Long after her military service to her country, she continues to serve as an educational site for the young and young at heart to remember and learn about WWII and American Naval History.
The USS Stewart began her service operating out of Miami as a "school ship" training student officers.
She escorted President Roosevelt in the presidential yacht down the Potomac River to rendezvous with USS Iowa in the Chesapeake Bay for his mission to Casablanca and Tehran. In 1944, she commenced North Atlantic convoy operations.
