The first USS Amphion was a former German passenger liner SS Köln for Norddeutscher Lloyd from 1899–1917. Köln had been interned in Boston on the outbreak of war in Europe and confiscated in April 1917 when the United States entered the war. The ship was under the control of the United States Shipping Board (USSB) that allocated commercial type ships to military or civilian use during the war. Köln was renamed Amphion and operated by USSB for the Army as United States Army Chartered Transport (U.S.A.C.T.) Amphion as an animal transport taking mules, horses and general cargo to forces in Europe. At the end of the war the USSB allocated the ship to the Navy, which used the ship from April to September 1919 as a troop transport for returning the United States Expeditionary Force from Europe.
The USSB contracted for the refurbishment of the ship after return by the Navy but the glut of war built ships, many new, resulted in Amphion lying idle from 1920 until sold for scrap in January 1924.

Köln was built in 1899 by J. C. Teckenborg A. G., Geestemünde, Germany, for Norddeutscher Lloyd.[1] The ship, signal letters QGTJ, was a, twin screw, awning deck type vessel of lighter construction in which the upper deck was not a full deck but a light covering deck above the main deck. There were two full decks.[1][2]
