 Although a new wing, it is considered an unofficial descendant of the "Northern Bombing Group" of World War I.Following the attacks on Pearl Harbor, the wing transferred to Naval Air Station San Diego, California, on December 10, 1941, and then to Camp Kearny on December 31.The first deployment for 1st MAW came in August 1942 when forward elements of the Wing arrived on Guadalcanal and made up the Cactus Air Force supporting the 1st Marine Division during the Battle of Guadalcanal.
