Like all attack transports, the purpose of the Heywood class ships was to transport troops and their equipment to hostile shores in order to execute amphibious invasions. To fulfill their mission, attack transports were fitted with a substantial number of integral landing craft, and were well armed with antiaircraft weaponry to protect themselves and their vulnerable cargo of troops from air attack in the battle zone.
