The USS Ortolan (AMCU-34), originally designated LCI(L)-976, was a large landing craft of the United States Navy constructed as part of the LCI(L)-351 class. Laid down on 15 March 1944 by the Consolidated Steel Corporation in Orange, Texas, she was launched on 10 April 1944 and commissioned shortly thereafter on 5 May 1944. Following her initial fitting out in Galveston, Texas, she departed on 2 June 1944 for the southwest Pacific, serving with the 7th Fleet. During her service in World War II, the vessel played a significant role in amphibious operations and troop transport. She arrived at Milne Bay, New Guinea, on 20 July and spent the subsequent months ferrying troops, supplies, and conducting training exercises. Her combat involvement intensified during the Leyte campaign, where she came under enemy air attack on 12 November 1944 and continued operations until December. Notably, she participated in landing assault troops at Ormoc Bay on 7 December and at Mindoro on 15 December. In early 1945, she supported the Luzon campaign, landings at Nasugbu, and various operations around Mindoro, Cebu, and Negros, frequently transporting troops and prisoners of war. Her service extended to occupation duties post-surrender, including transportation of Chinese troops to Taiwan. After the war, the vessel was decommissioned on 19 August 1946 and reclassified as a coastal minesweeper (AMCU-34) on 7 March 1952. She was converted at Charleston Naval Shipyard and recommissioned on 21 November 1953. Renamed USS Ortolan, she engaged in minehunting training and exercises along the United States East Coast, primarily in the 5th Naval District and Key West, Florida. Her activities included extensive training and development work until her decommissioning at Charleston on 23 June 1955. She was placed in reserve in the Florida Group at Green Cove Springs and was struck from the Navy List on 1 January 1960. Subsequently, she was sold for scrapping on 8 July 1960. Throughout her wartime service, the USS Ortolan earned four battle stars, underscoring her contributions in the Pacific Theater during World War II. Her operational history reflects her versatility, transitioning from a landing craft to a minesweeper, and exemplifies the adaptable nature of naval vessels during and after the conflict.
