APAs 240-247) were cancelled before completion. In addition, as part of the 1950s modernization of the Navy's amphibious force with faster ships, two more attack transports (APA-248 and APA-249) were converted from new Type C4-class ships, the s. Classes Classes of attack transports included: (2 ships) both built by the Furness Shipbuilding Company ca. 1928 and acquired by the navy in 1940 , originally AP-10 , AP-11 (5 ships) all built by the Alameda Works Shipyard as merchant ships ca. 1918 and acquired by the navy in 1940 , AP-12 , AP-14 , AP-15 , AP-16 , AP-17 (8 ships) Type P1 ship (2 ships) Type S4 ship (32 ships) Victory Ship (117 ships) Type C2 ship (3 ships) (4 ships) Type C3 ship (3 ships) (4 ships) (2 ships) (9 ships) (34 ships) (7 ships) Type C4 ship (2 ship) In use During World War II, attack transport served in the Pacific Theatre, taking part in many of the Navy's island hopping campaigns. Some attack transports were assigned to the European Theatre, participating in the invasions of North Africa, Sicily, Italy and Normandy. The last use was for the final WW2 Battle of Okinawa. Despite an impressive assembly of forces, the Aleutian campaign and the Northern Pacific Theater ranked as Admiral Nimitz's third priority in the overall Pacific Theater for receiving materiel and support. As a result, only attack transport (APA) ships were assigned for the assault, without support from any companion attack cargo (AKA) ships. This created extreme logistics burdens for the invasion force because it resulted in considerable overloading of the transports with both men and equipment. To compound problems, these forces were not able to assemble or train together before executing the Aleutian invasion on 11 May 1943. Lack of equipment and training subsequently resulted in confusion during the landings on Attu. Notable incidents was torpedoed off Cape Palos, Spain, 7 November 1942, and abandoned after going aground in Algiers Harbor, 25 November 1942. on 12 November 1942 was torpedoed by U-130 commanded by Ernst Kals who slipped past the escort screen to sink three transports. Edward Rutledges crew attempted to beach her but all power had been lost; she settled rapidly by the stern and sank with the loss of 15 men. on 11 November 1942 took a torpedo hit in No. 2 hold from U-173. The transport settled by the bow and began filling
