The USS Leon (APA-48) was a Bayfield-class attack transport built during World War II, serving from 1944 to 1946. Originally designated as USS Sea Dolphin (AP-93), she was renamed Leon on October 3, 1942, and redesignated as an attack transport (APA-48) on February 1, 1943. Laid down on February 6, 1943 under a Maritime Commission contract, she was launched on June 19, 1943. After her initial construction, she was accepted by the U.S. Navy and underwent conversion at the Bethlehem Steel Shipyard in Brooklyn, being commissioned on September 11, 1943, and then decommissioned on September 27 for fitting out. She was recommissioned in full on February 12, 1944. Leon’s service history was marked by participation in major Pacific campaigns. After shakedown at Norfolk, Virginia, she transported Marine and Seabee personnel to the Pacific, arriving at Pearl Harbor in April 1944. She trained extensively for amphibious assaults, notably practicing for the Mariana campaign. Her first combat operation was the invasion of Saipan on June 15, 1944, where her beach party successfully landed Marines under enemy fire, despite losing three boats. She later participated in the Palau invasion at Angaur Island in September 1944, and in the Philippines operations, transporting troops to Leyte and debarking divisions such as the 1st Cavalry and 77th Infantry. In April 1945, Leon took part in the Okinawa invasion, arriving on D-Day, April 1, and remained to unload cargo before escaping a stormy night anchorage. Post-war, she was involved in transporting troops and mail, including service in Operation Magic Carpet, bringing veterans home. She also played a role in the post-war occupation of Korea and China, transporting U.S. Marines and Chinese Nationalist troops. After returning to the United States in December 1945, Leon was decommissioned in March 1946 and transferred to the War Shipping Administration. She was sold in 1947 to the Isthmian Steamship Company, renamed Steel Chemist, and eventually scrapped in 1971. Throughout her wartime service, USS Leon earned four battle stars, marking her significant contribution to the Pacific theater.
