The President Jackson-class attack transport was a class of US Navy attack transport that saw service in World War II. Like all attack transports, the purpose of the President Jackson class was to transport troops and their equipment to hostile shores, and once there to execute amphibious invasions. To perform this task, attack transports were equipped with a substantial number of integral landing craft, and an abundance of antiaircraft weaponry to protect themselves and their vulnerable cargo of troops from air attack in the battle zone.
