The Harris-class attack transport was a class of US Navy attack transport which saw service in World War II. The purpose of any attack transport was to deliver troops and their equipment to hostile shores in order to execute amphibious invasions using an array of smaller integral landing craft. Being intended to serve in forward combat areas, these ships were well armed with antiaircraft guns to protect itself and its vulnerable cargo of troops from air attack in the battle zone.
