From 1937 into 1941, "Reid" participated in training and fleet maneuvers in the Atlantic and Pacific. During the attack on Pearl Harbor, "Reid"s gunners fired at the Japanese planes and downed one of them. After the attack, "Reid" patrolled off the Hawaiian Islands, Palmyra Atoll, and Johnston Island during December. In January 1942, she escorted a convoy to San Francisco, California. Returning to Hawaii for more patrol duty, she later steamed to Midway Island, and then twice more escorted convoys from Pearl Harbor to San Francisco.
