The USS Matsonia (ID-1589) was a notable early 20th-century ocean liner and troopship, constructed by the Newport News Ship Building Company in 1913. Originally serving as the SS Matsonia for the Matson Navigation Company, she was a passenger vessel designed for transoceanic travel, with a typical early 20th-century passenger liner profile. Her construction featured the elegant design typical of pre-World War I ocean liners, though specific dimensions are not detailed in the provided content. In 1918, during World War I, the vessel was requisitioned by the U.S. Shipping Board and transferred to the Navy, where she was commissioned as USS Matsonia on March 1, 1918, under the command of Captain John M. Luby. Her primary mission was troop transportation; she departed for France shortly after her commissioning, beginning her service with a convoy that included transatlantic crossings carrying troops and cargo. She completed six round-trip voyages to Europe before the armistice, during which she transported over 13,000 soldiers to the continent and returned with around 10,000. Her wartime service involved significant logistical efforts, including converting passenger spaces into troop bunks—rigging up approximately 3,000 soldier berths—and she endured a German U-boat attack during her second voyage to France, during which the U-boat was sunk near her convoy. Following the war, Matsonia resumed civilian service, returning to her original owner in September 1919. She continued as an ocean liner until 1937, when she was sold to Alaskan interests and renamed SS Etolin. In 1940, the U.S. Army chartered her for wartime service, retaining her name. During World War II, she acted as a troopship, participating in early operations such as transporting troops to the Philippines and later operating routes between the U.S., Australia, and Hawaii. She underwent extensive overhauls, including repairs in Baltimore in 1943, and crossed the Pacific twice to Japan and Okinawa in 1945. After the war, Etolin served in the U.S. to Panama route before being placed in the James River Reserve Fleet in 1946. She was ultimately scrapped in Baltimore in 1957. Her service record highlights her versatility as both a passenger liner and a vital wartime troopship, reflecting the maritime needs of the United States across both world wars.
