USS Northern Pacific was built as the passenger ship SS Northern Pacific at Philadelphia, Pennsylvania by William Cramp & Sons under supervision of the Great Northern Pacific Steam Ship Company for the Spokane, Portland and Seattle Railway Company. Northern Pacific, along with sister ship SS Great Northern, were built to provide a passenger and freight link by sea between the Great Northern Railway Lines and Spokane, Portland and Seattle Railway terminal at Astoria, Oregon and San Francisco beginning in spring of 1915. The ship was acquired on 17 September 1917 for use as a transport ship for the United States Navy during World War I and later as USAT Northern Pacific, a United States Army transport. She was destroyed by fire in 1922.



Northern Pacific and sister ship SS Great Northern were built by William Cramp & Sons of Philadelphia, Pennsylvania for the Great Northern Pacific Steam Ship Company, Astoria, Oregon to the order of the Spokane, Portland and Seattle Railway Company to serve between Astoria and San Francisco.[2][3] Contracts for both ships were let on 26 April 1913 with keel laying for Northern Pacific on 23 September 1913, the day after Great Northern, and launch on 17 October 1914 with service due to start in March 1915.[2]

Northern Pacific and sister ship SS Great Northern were designed for 856 passengers and 2,185 tons of freight with a 23 knot speed making possilbe the run between the ports in 25—26 hours, equal to the time for an overland route, under favorable conditions and thus allowing direct service to San Francisco from the east using Great Northern Railway Lines.[2] Both ships were classed A100 according to British Lloyds and met the latest requirements of the United States Steamboat Inspection Service.[2]

Design specifications were for a 8,255 GRT ship with 524 ft (159.7 m) length over all, 500 ft (152.4 m) length between perpendiculars, 63 ft (19.2 m) beam, 21 ft (6.4 m) full load draft, 50 ft 8 in (15.4 m) depth molded to A deck with 2,185 DWT and approximately 200,000 cubic feet of cargo space.[2] The 856 passenger capacity was broken down into 550 first class, 108 second class and 198 third class served by a crew of 198.[2] The double bottomed hull was divided into eleven watertight compartments with ten extending to the bottom of second deck above full load waterline.[4]

Twelve Babcock & Wilcox water tube boilers provided steam for Parsons turbines on three shafts with a requirement that the 23 knot speed be available with steam from only ten boilers.[4] One high pressure turbine 21 ft 7.5 in (6.6 m) long with 5 ft 8 in (1.7 m) diameter rotor drum with four stages of expansion and two low pressure turbines, with integrated astern and each 32 ft 2 in (9.8 m) long with 7 ft 8 in (2.3 m) ahead and 6 ft 7 in (2.0 m) astern diameter rotor drums, develop about 25,000 shaft horsepower at 325 revolutions.[5] Four 35 kilowatt, 110 volt steam driven Diehl Manufacturing Company generators provided electric power for lighting and auxiliary electric machinery.[6]

Northern Pacific departed Philadelphia for San Francisco with all reservations taken on 25 March 1915.[7]

Navy and Army service

She was acquired by the United States Shipping Board (USSB) from the Spokane, Portland and Seattle Railway of Portland, Oregon, on 17 September 1917 and commissioned on 3 November 1917 at Bremerton, Washington, with Lieutenant Commander Alfred T. Hunter in command.[1]

Under Naval operation she departed San Francisco on 7 March for New York via the Panama Canal. Joining the Cruiser and Transport Squadron during the war, Northern Pacific operated between the Army's Hoboken Port of Embarkation, Hoboken, New Jersey and Brest, France, making a total of 13 trips taking 22,645 troops and passengers to France and returning 9,532 to the United States. The influenza epidemic hit the ship hard in September 1918 en route to Brest. Cots were set up in the brig and in the open corridors. There were 7 deaths. On 2 October, sister ship Great Northern collided with the British ship Brinkburn, which caused Great Northern to lose contact with the convoy. Northern Pacific searched and found her sister seaworthy enough to rejoin the convoy.[1]

Northern Pacific ran aground off Fire Island, New York on 1 January 1919. Her troops were transferred to other ships. She was refloated on 18 January, and proceeded to Staten Island. She was decommissioned on 20 August 1919 and was transferred to the Army Transport Service (ATS) on that date.[3][1]

USAT Northern Pacific was assigned to the ATS Pacific Fleet and home ported at Fort Mason in San Francisco.[3] On 12 September 1919 the ship departed for Siberia in order to transport the American Expeditionary Force Siberia to the Philippines.[3]

Sale and fire

Returned to the USSB on 22 November 1921, she was sold to the Pacific Steamship Company on 2 February 1922; while being towed to their yard at Chester, Pennsylvania, she was destroyed by fire.[1]
