After completion of repairs on 22 December, "Sicard" participated in amphibious landing exercises off San Diego; and then sailed on 24 April 1943 from San Francisco with a convoy of troop transports for the assault on Attu in the Aleutians. "Sicard" was to have acted as a landing craft control vessel for the operation; but, on the night before the landing, she collided with the destroyer, "Macdonough" (DD-351), in a dense fog. "Sicard" towed "McDonough" into Adak, and then proceeded to San Francisco for repairs, which lasted to 29 July. She was more fortunate during the Kiska landings and successfully guided the waves of assault boats to the beach there between 15 and 18 August. She performed local patrol and escort duties in the Aleutians, and then escorted a convoy to Pearl Harbor, where she arrived on 15 September.
