The USS Henderson (AP-1) was a significant transport vessel built by the Philadelphia Navy Yard, launched on June 17, 1916, and commissioned on May 24, 1917. As a World War I-era ship, she was designed to carry up to 1,500 troops and 24 mules, serving as a vital link between the United States and European theaters. Her primary mission was transporting American soldiers to France, arriving at Saint-Nazaire on June 27, 1917, and conducting multiple voyages throughout the war, including eight transatlantic trips with troops and supplies. During her service, Henderson established two large base hospitals in France and demonstrated resilience amid dangers such as submarine threats and onboard fires. Notably, she narrowly escaped attack from a torpedo near the USS Antilles in October 1917 and fought a significant onboard fire in July 1918, which she managed to contain with the help of destroyers. She also likely rammed a German U-boat, U-139, in August 1918, causing damage to the submarine's periscopes and conning tower, an incident that highlighted her aggressive defense against enemy submarines. After the armistice, Henderson returned over 10,000 veterans to the U.S. and transitioned to duties in the Caribbean, transporting Marines, dependents, and supplies. She participated in notable events, including observing fleet maneuvers and President Warren G. Harding’s Alaska inspection tour in 1923. In the mid-1920s, she was involved in fleet operations and made a prominent deployment to China, stationed in Shanghai for six months to protect American nationals. On December 7, 1941, she was outbound from Pearl Harbor during the attack, successfully avoiding destruction and later serving as a transport in the Pacific War. In 1943, Henderson was decommissioned and converted into a hospital ship, renamed USS Bountiful (AH-9). As Bountiful, she participated in the Mariana, Palau, and Iwo Jima campaigns, establishing one of the Navy’s few blood banks, and served in Japan during the occupation before supporting nuclear tests at Bikini Atoll. She was decommissioned in 1946, awarded four battle stars for WWII, and ultimately sold for scrap in 1948. This vessel’s service history underscores its importance in both World Wars, exemplifying versatility, resilience, and maritime significance across decades of U.S. naval operations.
