The second Dorchester (APB-46), a Benewah-class barracks ship, was in commission for only a few months during the occupation of Japan after World War II.
USAT Dorchester was famous for the Four Chaplains. Refering to that United States Army Transport as "USS Dorchester" is incorrect; she was never commissioned into the United States Navy.
