This massive, comprehensive volume is the first to give the reader a definitive description of this neglected bomber, its development, testing, and manufacture. The role of the enigmatic aviation icon Glenn L. Martin is described in the development of the American aviation industry and the Marauder. The author made extensive use of the massive document and photo collections of the Marauder Archives at Akron and Tucson, and the Air Force collection at the NMUSAF. Martin Company design and production information and flight and test evaluations, along with original Company Flight, Parts, and Maintenance Manuals, and rare archival microfilm of original material were also used. The author was given unprecedented access to the family records of B-26 designer Peyton Magruder. The text is complemented by archival photos and drawings, and new color photos of the Marauders at the NMUSAF, Fantasy of Flight, and MAPS Museum. -

USAFAlmanac ■ Gallery of USAF Weapons By Susan H.H. Young The B-1B’s conventional capability is being significantly enhanced by the ongoing Conventional Mission Upgrade Program (CMUP). This gives the B-1B greater lethality and survivability through the integration of precision and standoff weapons and a robust ECM suite. CMUP will include GPS receivers, a MIL-STD-1760 weapon interface, secure radios, and improved computers to support precision weapons, initially the JDAM, followed by the Joint Standoff Weapon (JSOW) and the Joint Air to Surface Standoff Missile (JASSM). The Defensive System Upgrade Program will improve aircrew situational awareness and jamming capability.
