USS Ward was laid down as a 1,247-long-ton (1,267 t) Wickes-class destroyer in the United States Navy during World War I, later converted to a high speed transport in World War II. She was responsible for the first American-caused casualties in the Pacific in World War II when she engaged and sank a Japanese midget submarine before Japanese aircraft arrived in the attack on Pearl Harbor, killing both crewmen on board.

The Wickes-class destroyers were a class of 111 destroyers built by the United States Navy in 1917–19. Together with the six preceding Caldwell-class and following 156 subsequent Clemson-class destroyers, they were grouped as the "flush-deck" or "four-stack" type. Only a few were completed in time to serve in World War I, including USS Wickes, the lead ship of the class.
