The USS Ottawa (AKA-101) was a Tolland-class attack cargo ship constructed during the final months of World War II. Built by the North Carolina Shipbuilding Company in Wilmington, she was laid down on October 5, 1944, as a Type C2-S-AJ3 vessel under a Maritime Commission contract and launched on November 29, 1944. She was commissioned at the Charleston Navy Yard on February 8, 1945, and measured approximately 459 feet in length, with a beam of about 62 feet, designed to carry both cargo and landing craft for amphibious operations. Following her outfitting and shakedown training out of Norfolk, Virginia, she loaded cargo and set sail for the Pacific theater in March 1945. Her service included transporting military cargo to Pearl Harbor, Eniwetok, Ulithi, and Okinawa, as well as delivering vehicles and supplies to various Pacific islands in support of post-war occupation efforts. Notably, she arrived in Okinawa just before the cessation of hostilities in August 1945 and participated in transporting elements of the 2nd Marines to Nagasaki for occupation duties. In addition to her cargo operations, USS Ottawa supported Operation Crossroads at Bikini Atoll in mid-1946, serving as a barracks and stores ship for the deployed Seabees. She observed the atomic tests Able and Baker from a safe distance, away from the immediate blast zones, and conducted routine duties in the lagoon area afterward. Her post-war activities included shuttling between U.S. ports and participating in occupation and transportation missions in Asia. Decommissioned on January 10, 1947, she was returned to the Maritime Commission and later sold into commercial service under the name Andrea F. Luckenbach, operated by Luckenbach Steamship Lines. Her maritime career ended when she was lost after stranding three miles off Kohala Point, Kauai, in Hawaii, on March 11, 1951. The USS Ottawa exemplifies the rapid wartime construction and deployment of cargo ships, playing a vital logistical role during the closing stages of World War II and the immediate post-war period.
