The USS Spica (AK-16) was a Sirius-class cargo ship commissioned by the U.S. Navy during World War II, primarily tasked with transporting essential supplies and equipment to support naval operations in the Pacific Theater. Originally built as the SS Shannock in 1919 by the American International Shipbuilding Corporation at Hog Island, Pennsylvania, this vessel was acquired by the U.S. Shipping Board and renamed Spica in 1921. For nearly two decades, she remained out of commission, stationed at various U.S. ports including New York City, Charleston, and Philadelphia. Reactivated in March 1940 at Norfolk, Virginia, Spica was assigned to the 13th Naval District, where she operated along the Alaskan coast and in the Aleutian Islands. Her service included participation in the campaign to reoccupy Attu, highlighting her role in critical Pacific campaigns. In late 1943, she relocated to San Francisco before heading to the Pacific theater, reaching Kwajalein Atoll in January 1944 after passing through Funafuti. She then returned to Seattle in March 1944, resuming her Alaskan supply runs until mid-1945. Notably, in July 1944, she delivered supplies to explore Naval Petroleum Reserve #4, supporting construction battalions involved in resource exploration. From mid-1944 to March 1945, Spica conducted multiple voyages between Seattle and Hawaii, supporting the Pacific island-hopping campaigns. Her operational duties extended into September 1945, after which she was deemed surplus and decommissioned in January 1946. Her name was struck from the Navy list in February 1946, and she was sold to J. T. Robinson, Ltd., in 1947. Throughout her service, USS Spica earned one battle star and contributed significantly to logistical support during critical phases of the Pacific War, exemplifying the vital role of cargo ships in naval operations.
