The Type P1 ship is a United States Maritime Administration (MARAD) designation for World War II passenger ships. P1 was used in World War II, Korean War and Vietnam War. Type P1 were the smallest of the P-class ships, at 400 to 500 feet (120 to 150 m) long. Two P1-S2-L2 ships were built for the Navy and used as attack transports (APA). Many P1 type ships were built on Type C3-class ship hulls.^[1]

• The P1-S2-L2 Doyen-class attack transports were a series of two ships. The first American assault military transports. Made with an aft ramp for the launching of small landing craft or for the unloading of tanks.
