AAC - 2nd Air Force Pillow

From December 1941, 2d Air Force organized air defense for the northwest Pacific Ocean coastline of the United States (1940–1941) and flew antisubmarine patrols along coastal areas until October 1942. It appears that immediately after 7 December 1941, only the 7th, 17th, 39th and 42d Bombardment Groups under II Bomber Command were available for this duty. In late January 1942, elements of the B-25 Mitchell-equipped 17th Bombardment Group at Pendleton Field, Oregon were reassigned to Columbia Army Air Base, South Carolina ostensibly to fly antisubmarine patrols off the southeast coast of the United States, but in actuality came to prepare for the Doolittle Raid against Japan.
