While en route to operations in the Aleutian Islands on 27 July 1942, "Chandler" collided with the destroyer minesweeper in a heavy fog. She underwent repairs from 11 August to 27 September 1942 at Mare Island Navy Yard. On 5 October 1942, she arrived at Dutch Harbor in the Aleutians for patrol and convoy escort duty in the Aleutians. In May 1943, she covered the amphibious landings at Attu, and in August 1943 the landings at Kiska. Leaving the Aleutians in October 1943, "Chandler" was readied at San Francisco for duty farther south in the Pacific.
