In 1942, "Ward" was sent to the West Coast for conversion to a high-speed transport. Redesignated APD-16 in February 1943, she steamed to the South Pacific to operate in the Solomon Islands area. She helped fight off a heavy Japanese air attack off Tulagi on 7 April 1943, and spent most of the rest of that year on escort and transport service. In December, she participated in the Cape Gloucester invasion. During the first nine months of 1944, "Ward" continued her escort and patrol work and also took part in several Southwest Pacific amphibious landings, among them the assaults on Saidor, Nissan Island, Emirau, Aitape, Biak, Cape Sansapor, and Morotai.
