The USS Tortuga (LSD-26) was a Casa Grande-class dock landing ship constructed for the United States Navy, representing a significant asset in amphibious warfare capabilities. Laid down on 16 October 1944 at the Boston Navy Yard and launched on 21 January 1945, she was commissioned on 8 June 1945. As a Casa Grande-class vessel, Tortuga was designed to carry and support landing craft, facilitating amphibious operations by deploying troops and equipment directly onto hostile shores. Initially, Tortuga conducted shakedown operations in the Virginia Capes area and was en route to the Pacific when Japan surrendered in August 1945. Her early service involved operations in Okinawa, Korea, China, and Japan, where she supported amphibious forces by repairing small craft and providing mobile support. She was decommissioned and placed in reserve at San Diego in August 1947 but was recommissioned in September 1950 in response to the Korean War. During her Korean service, Tortuga participated in amphibious support operations, including a feint landing at Inchon, and supported operations off Wonsan and Kojo, North Korea. She also contributed to the study of enemy junks for future combat tactics. In 1954, Tortuga was involved in "Operation Passage to Freedom," supporting the evacuation of Vietnamese civilians and refugees from Haiphong to South Vietnam. Throughout the 1950s and 1960s, she remained active in the Western Pacific, participating in exercises, support missions, and troop transports, adapting to the evolving needs of Cold War and Southeast Asian conflicts. Her Vietnam deployments included supporting Operation Game Warden in the Mekong Delta, serving as a floating base for river patrols and helicopter detachments, and participating in combat control operations during major campaigns such as Operation Daring Rebel and Operation Gallant Leader. Tortuga's service concluded with her decommissioning at Mare Island in January 1970. She was transferred to the Maritime Administration, placed in reserve, and struck from the Navy list in 1976. From 1983 to 1987, she served as a target ship, enduring missile tests, until she ran aground on San Miguel Island in December 1987. Ultimately, she was scrapped on site after breaking her tow during a storm, marking the end of her maritime service. Tortuga earned multiple engagement stars for her service in both Korea and Vietnam, reflecting her importance in U.S. amphibious operations during the Cold War era.
