The information about the fate of the USS Alcona (AK-157) primarily comes from official naval archives and historical accounts detailing the ship’s service during and after World War II.

Construction and World War II Service: The USS Alcona was built as part of the Maritime Commission's wartime shipbuilding program, launched in May 1944, and commissioned into the Navy on 15 September 1944. It served primarily in the Pacific theater, providing cargo transport during the war(USS Alcona - Wikipedia)(Cargo Ship Photo Index ).

2. Post-War and Decommissioning: After the end of World War II, the Alcona was decommissioned on 6 May 1955 and placed in reserve in the Atlantic Fleet at Charleston, South Carolina. It remained in reserve until it was struck from the naval register on 1 April 1960(Cargo Ship Photo Index ).

3. Final Disposition: The final fate of the USS Alcona was its sale for scrapping. On 28 July 1960, it was transferred to the Maritime Commission, which arranged for its dismantling. The dismantling process was completed by 31 October 1961(Cargo Ship Photo Index )(USS Alcona - Wikipedia).

This final disposition is documented in multiple naval histories, including the Dictionary of American Naval Fighting Ships and other naval photo archives like NavSource(Cargo Ship Photo Index )(USS Alcona - Wikipedia).
