The USS U. S. Grant (AP-29) was a distinguished transport ship that played a vital role in both World Wars, with a rich history originating from her construction as the German ocean liner König Wilhelm II. Launched on 20 July 1907 at Stettin, Germany, by Vulcan Aktiengesellschaft, the vessel was originally built for the transatlantic passenger trade, operating between Hamburg and Buenos Aires under the Hamburg-Amerika Line. She was a steel-hulled screw steamer, demonstrating early 20th-century maritime design with robust construction suited for long-distance passenger service. During World War I, the vessel was interned in Hoboken, New Jersey, to avoid capture by the Royal Navy. After the U.S. entered the war in 1917, she was seized, repaired following an unsuccessful sabotage attempt by her German crew, and commissioned into U.S. service as USS Madawaska (ID-3011). She made ten transatlantic voyages during WWI, transporting nearly 12,000 men to Europe, and later repatriated 17,000 soldiers after the armistice. Post-war, she participated in evacuations from Siberia and was eventually laid up in the United States. Reactivated and extensively refitted, including the addition of modern boilers, she was renamed USS U. S. Grant in 1922, in honor of the notable general and president Ulysses S. Grant. As an Army Transport Service vessel for nearly two decades, she regularly transported troops, passengers, and supplies across the Pacific, serving routes from San Francisco through Hawaii, Guam, Manila, and China. Notably, she nearly foundered in 1939 after grounding on a reef in Guam, but she was freed with the cooperation of naval vessels and resumed her voyage. Reacquired by the Navy in 1941, she was armed and designated AP-29, serving throughout World War II. Her service included transporting troops and equipment to Alaskan and Hawaiian bases, supporting the Aleutian Campaign, and participating in the Kiska landings. In 1945, she moved to the Pacific theater, including a voyage to Okinawa, before returning stateside. Decommissioned in November 1945, she was struck from the Navy List and sold for scrapping in 1948. Her service earned her one battle star, marking her as a notable vessel in U.S. maritime and military history.
