Construction

C3-S-A2 troop transports were designed to carry roughly 2,100 troops. Here 1,958 arrive in Boston from Europe on 26 July 1945

A Type C3-S-A2 troop transport with similar mast configuration

Sea Owl was laid down 22 July 1943 for the U. S. Maritime Commission by Ingalls Shipbuilding Corporation of Pascagoula, Mississippi as a Type C3-S-A2 ship, yard hull 407, USMC hull 863 under a contract of 23 April 1942. The ship was launched on 17 December 1943 and completed on 27 June 1944 by Ingalls as a troop transport with capacity for 2,156 passengers. Sea Owl was registered with U.S. Official Number 245730, Signal WPIT and delivered to the War Shipping Administration for operation the same day for operation under a General Agency Agreement by American Export Lines.^{[3][1][2][4][5]}

The 1945 U.S. registry information for Sea Owl gives characteristics as 7,886 GRT, 4,600 NRT, 466.5 ft (142.2 m) registry length, 69.6 ft (21.2 m) beam and depth of 29.5 ft (9.0 m), 8,500 horsepower and crew of 53.^[1]

Service history

War Shipping Administration (1944–1946)

Sea Owl was allocated to Army requirements and operated by a United States Merchant Marine crew. A contingent of the US Naval Armed Guard were assigned responsible for the ship's guns. The Army allocation led to erroneous conclusions the ship was an Army Transport, designated USAT, which was a term applied to ships owned or bareboat chartered by the Army.^[6][7] All ships engaged in Army troop transport had a complement of the US Army Transportation Corps (Water Division) and a representative of the Port of Embarkation^{[note 2]} commander assigned, a Transport Commander, in command of all Army passengers but not the ship.^[8]

Sea Owl's shakedown cruise was from Pascagoula to New York City, followed by a voyage to Newport News, Virginia, to pick up her first troop complement, an Army battalion headed for Naples.^[9] The ship departed Hampton Roads Port of Embarkation at Norfolk on 27 July 1944 and returned to New York on 31 August. During the remainder of 1944 the ship made two trips from the New York Port of Embarkation to Europe. The first departed on 12 September for Milford Haven and Cherbourg, France. The second was on 22 October for the Mersey, the Bristol Channel and Avonmouth with return to the Boston Port of Embarkation on 16 November. On 24 November the ship sailed for Southampton with return to New York on 22 December 1944.^[4]

The first four voyages of 1945 were from New York. On 10 January 1945 Sea Owl departed New York for The Solent, Le Havre, Plymouth and Southampton. The ship then departed again for Le Havre and The Solent on 27 February. Southampton was again the destination of a voyage on 4 April. On 10 May the ship again departed New York for Le Havre and Southampton with a return to Boston from which the ship departed on 8 June for Le Havre returning to New York. On 22 July 1945 a change was made as war in Europe ended with a mission to redeploy troops to the Pacific. The ship departed New York for Gibraltar, Leghorn and Naples but instead Sea Owl was diverted to Boston. The ship then operated out of Boston to Europe with a voyage on 24 August for Le Havre. On 15 September the destination was Marseilles with a return to Hampton Roads. From there the ship sailed on 13 October again for Marseilles and again on 10 November for Naples and Marseilles with return to Hampton Roads on 5 December 1945.^[4]

On 15 December 1945 Sea Owl departed Hampton Roads to transit the Panama Canal for the Pacific arriving 14 January 1946 at Nagoya. With a stop at Incheon, Korea (named Jinsen during Japanese occupation) the ship returned to the Seattle Port of Embarkation 14 February 1946 to complete troop transport service.^[4]

Sea Owl was also used to transport German POWs to the United States.^[18]

Isthmian Lines (1947–1971)

Steel Scientist in 1961

Sea Owl was transferred to the Maritime Commission in 1946. A$282,00 contract for conversion into a cargo ship was awarded to J.K. Welding Co., of Yonkers, NY, to be completed in 70 calendar days. In 1947 she was sold to Isthmian Lines of New York.^[3]

Beginning in 1947 it operated in Isthmian service as SS Steel Scientist hauling cargoes from Asia principally to U.S. Gulf ports carrying jute, gunnie sacks, shellac, and other materials. She was sold to Taiwan Shipbreakers, arrived at Kaohsiung 9 July 1971 and scrapped during that month.^[3]
