The USS President Monroe (AP-104) was a President Jackson-class attack transport built for the U.S. Navy during World War II, originally constructed as a C3-P&C type vessel for American President Lines. Laid down on November 13, 1939, by Newport News Shipbuilding and Drydock Company, and launched on August 7, 1940, she was among seven similar ships designed for around-the-world service. At nearly 500 feet in length, she was built for passenger and cargo transport, but her design was adapted for wartime service. Initially, President Monroe was about to begin her maiden voyage when the attack on Pearl Harbor interrupted her plans. She was quickly acquired by the War Shipping Administration and repurposed for troop transport. Her service commenced in early 1942, ferrying troops and supplies to the Pacific theater. Notably, she participated in the first large convoy to Australia after Pearl Harbor, landing troops at Suva in January 1942. Throughout 1942 and 1943, she supported operations across the Pacific, including transporting construction battalions, assault troops, and cargo to key locations such as Pago Pago, Kwajalein, Eniwetok, and Guadalcanal. In August 1943, she was commissioned as USS President Monroe (AP-104) following conversion and outfitting at Portland, Oregon. Her service included participation in the Gilbert Islands invasion, the landings at Eniwetok and Guam, and logistical support for the Battle of Iwo Jima. She also was involved in Operation Magic Carpet, bringing servicemen home after the war. Throughout her wartime career, President Monroe earned five battle stars, reflecting her significant contribution to the Pacific campaign. She was decommissioned in January 1946, returned to commercial service, and later sold in 1965 to a Greek shipping company, renamed Marianna V, and ultimately scrapped in 1973. Her service record underscores her importance as a versatile troop transport and logistical vessel in World War II maritime operations.
