The USS Shasta (AE-6) was an ammunition ship built under a Maritime Commission contract as a C2 type cargo vessel by Tampa Shipbuilding Company, Tampa, Florida, with her keel laid on 12 August 1940. Acquired by the U.S. Navy on 16 April 1941 and launched on 9 July 1941, she was commissioned on 20 January 1942 and named after Mount Shasta in California. Designed to serve as an ammunition replenishment vessel, Shasta was a vital component of the Pacific Theater during World War II. Her service record includes ten transpacific voyages beginning in November 1942, where she supplied ammunition to the Battle Fleet across islands in the western Pacific, supporting campaigns in the Gilberts, Marianas, Palaus, and Philippines. Notably, in 1945, she participated in the first successful underway ammunition replenishment and supported operations during the Battle of Iwo Jima, even under Japanese shore battery fire. Her wartime service was marked by resilience, including surviving a fierce typhoon off Okinawa on 5 June 1945, which damaged her cargo and caused loose depth charges and projectiles on deck, yet she continued her mission. She also survived kamikaze attacks at Ulithi and drifting mines near Okinawa. After the war, Shasta operated at Leyte Gulf, taking on cargo and supporting post-war efforts until her decommissioning at San Diego on 10 August 1946. Recommissioned in 1953, she joined the Atlantic Fleet, serving primarily with the 6th Fleet in the Mediterranean and along the Atlantic coast. Her activities included supporting crises in Jordan and Lebanon, testing military instruments, and participating in NATO exercises. In 1966, Shasta made a notable circumnavigation of the globe, traveling through the Suez Canal, and visiting Malta and Spain. Her final deployment was interrupted during the search for the USS Scorpion, and she was placed in reduced status in 1969. She was decommissioned and sold for scrapping in 1970. Throughout her service, USS Shasta earned five battle stars for WWII and one for Vietnam, underscoring her significant role in naval logistics and wartime operations.
