Bomb Rack was a 9.5×13-inch-size free magazine-newspaper produced by the 20th Air Force for United States Army Air Forces airmen serving at AAF bases on Guam, Tinian, and Saipan in the months following World War II. Although serious articles occasionally appeared within, Bomb Rack's tone was often light-hearted and humorous with numerous photos and pin-ups, as well as a full page of locally drawn cartoons. Sports were covered extensively, as were topics important to airmen at the time such as education and returning to the United States as quickly as possible. The exact number of issues published is unknown, but copies were distributed at least between October 7, 1945, and January 21, 1946, and ran through number 16. Bomb Rack's length was eight pages, but sometimes also included a one-page bulletin containing official information. Unlike the Air Force's official histories from the time that focused on operations, manpower, and so forth, periodicals such as Bomb Rack provide a glimpse of everyday life in the Air Force.
Little is known about Bomb Rack's origins except that volume one number one was October 7, 1945. During World War II, AAF organizations and units often had their own newsletters, so it is possible that the 20th Air Force also had a newsletter that preceded Bomb Rack. That, however, is speculation, and precisely when the magazine ceased production is also unknown. From 1945-49, the 20th Air Force's headquarters was located at Harmon Field near the cliffs above Guam's famous resort beach on Tumon Bay, and a newsletter entitled Harmon Rocket was published at Harmon Field at least in 1945, though almost nothing is known of that publication. By 1949 Andersen Air Force Base, Guam's only remaining Air Force base, was publishing its own weekly paper called Tropic Topics.
What makes Bomb Rack more of a "magazine" than a newspaper or newsletter is its size, the quality of its paper, and most significantly, its format. Each issue's cover is a single photograph (except for October 7, 1945, which is a sketch of then Lieutenant General Nathan Farragut Twining) with a brief mention of the content. Issues normally included a letters page, a political cartoon (sometimes military related), numerous feature stories, a sports section, and a cartoon page.
