The USS Rockingham (APA/LPA-229) was a Haskell-class attack transport built during World War II, designed to support amphibious operations. Constructed by Kaiser Shipbuilding Corporation in Vancouver, Washington, she was laid down on September 11, 1944, and launched on November 1, 1944. The vessel was acquired by the U.S. Navy on a loan-charter basis from the Maritime Commission and commissioned at Astoria, Oregon, on November 22, 1944. Designed as a Victory ship conversion, the Rockingham measured approximately 455 feet in length, with a beam of around 62 feet, and a draft of roughly 24 feet. She was equipped to carry over 1,200 troops and had the capability to transport cargo and provide logistical support for amphibious assaults. Following her commissioning, the Rockingham underwent trials in Seattle and shakedown off San Pedro, California. She reported to the Pacific Fleet at the end of 1944 and participated in amphibious training off Southern California. In early 1945, she loaded troops and cargo at San Diego, heading to Pearl Harbor and the Marianas, including Eniwetok, Saipan, and Ulithi. Her service was marked by participation in the Okinawa campaign, where she debarked troops on April 26, 1945, and experienced enemy air attacks, including kamikaze strikes. Notably, she assisted USS Terror, which was severely damaged by a suicide plane, and took casualties onboard. After the war, Rockingham was involved in Operation Magic Carpet, repatriating U.S. troops from the Philippines and supporting post-war occupation efforts in Japan. She was also part of the atomic bomb tests at Bikini Atoll in 1946, known as Operation Crossroads. Decommissioned in March 1947, the Rockingham was placed in the Pacific Reserve Fleet at San Francisco. She was transferred to the Maritime Administration in 1958 and ultimately scrapped in 1979 by Don Kur Steel Corporation in South Korea. Throughout her service, she earned one battle star for her participation in World War II.
