The USS Allioth was a Crater-class ship. Its main function was that of a cargo vessel. This ship served the US Navy in the operations of World War II. Its name was inspired by a constellation located in Ursa Major. The USS Allioth had different duties: delivering cargo, troops, and equipment. It was laid down in 1943 by the Permanente Metals Corporation at Richmond, California. The vessel was then acquired by the US Navy in October the same year. The next step was the commissioning which took place on the 25th of October at Portland, Oregon. The assigned commander was George F. Prestwich. The ship’s first mission was serving the Service Squadron 8. During its years of service, the USS Allioth supplied the army with cargo and traveled to places such as the Marshall Islands, the Gilbert Islands, Tarawa, Peleliu, Palau Islands. One of the most memorable events related to the Allioth is the Japanese attack that occurred in November 1944 when the ship was sailing to Pearl Harbour. Later that year, the vessel was converted into an Aviation Supply Issue Ship and started supporting aircraft in the Philippine Islands and the Ryukyu Islands. The USS Allioth was decommissioned in 1946 and placed in the National Defense Reserve Fleet at Suisun Bay, California.
