Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Every week the TV news highlights the routine use of drones and guided missiles against terrorist enemies and the recreational use of drones has become commonplace. The Nazi WWII development of guided missiles and bombs is often given credit for America's Cold War success in this realm. However, it was during that war that America, and the Air Force, in particular, also began the development of systems and weapons that laid the foundation for today's technology. 'Off Target' relates in detail the then "Secret" research, development, and combat employment of these early guided bombs, missiles, and drones from 1917 to 1948. Using formerly Secret/Confidential manuals, reports, microfilm print outs, and photos, collected over 40 years, author Wolf, gives the air war historian and enthusiast a detailed look at this unknown topic that progressed from biplane drones to sophisticated post-WWII guided missiles. Among the subjects discussed are Sperry's aerial torpedo and the Kettering "Bug" of WWI to WWII's early rudimentary GB Series Glide Bombs to the more sophisticated VB Series that evolved from radio, heat, light, or television guidance. The Aphrodite/Joseph Kennedy B-17, BQ, TDR, and target drones are discussed as are the SWOD, GLOMB, GORGON, and JB Jet bomb series.

Of all the Allied bombers of WWII, the Douglas A-20 Havoc is probably the least well known, but was a major contributor to the air war effort, flying yeoman and unheralded missions not only for the USAAF, but also for the Royal Air Forces of Britain, South Africa, and Australia; the Vichy and Free French Air Forces; and most importantly, for the Soviet Army and Navy Air Forces, where more A-20s flew than with the USAAF. This is the sixth in the "Ultimate Look" series and presents the same meticulous depth of research as the other books, using a multitude of original sources, technical manuals, and photographs. It includes an in-depth look into the history of the Douglas Company, its founder, Donald Douglas, and its legendary designer, Ed Heinemann. This book is truly the definitive look at the Havoc.

The XB-40 and XB-41 were secret, little-known experimental modifications of the B-17F and B-24D, respectively, into heavily-armed bomber gunships sometimes referred to as "bomber escorters". They were developed during early World War II in response to the lack of a USAAF long-range fighter aircraft able to escort and protect regular B-17 formations making the round trip from Britain deep into Germany. Using many formerly-classified documents from his large microfilm collection, William Wolf presents their previously-unpublished history. It describes in depth for the first time the politics and development and associated problems of both escorter types. Unfortunately, these "protecters" were found wanting in several ways - after the addition of guns and ammunition they became overweight and tail-heavy causing center of gravity problems and each encountered numerous delays in the development and delivery of their various armament additions and improvements, particularly the Bendix chin turret. In the end, the YB-40 participated in only 14 lackluster operational service test missions during mid-1943 before being withdrawn from service. The XB-41 Liberator never saw operational testing before also being cancelled for its poor performance. The failure of the gunship concept left a huge hole in the capabilities of the Eighth Air Force. Their failure, however, spurred the adoption of the Merlin-powered P-51 Mustang, the outstanding escort fighter that was key to Allied victory in the air war over Europe.

In 1935 the USAAC wanted to build a potential intercontinental bomber, a 'Guardian of the Hemisphere,' and granted Donald Douglas a contract to build the world's largest bomber. The groundwork for the intercontinental bomber had been laid in the previous two decades by the courageous military and civilian pilots who risked their lives to set new distance and endurance records. After World War I the future Axis and Allied nations built larger aircraft and finally during World War II Germany and Japan became intent on developing intercontinental bomber to retaliate against America. While the XB-19 never flew as an intercontinental bomber or even as a combat bomber; its contributions as a 'Flying Laboratory' significantly influenced the development of the Consolidated B-36 Peacemaker, the world's first true intercontinental bomber. Since the XB-19 project was top secret and there was only one example built there is little information remaining for researchers. Over the years Bill Wolf has collected the largest quantity of XB-19 material and a number of photographs, including a copy of the original Army Air Force acceptance of the aircraft, first-hand narratives of its first flight, and other USAAC and Douglas Company documents. This book provides a superbly illustrated history of the XB-19 intercontinental bomber and the text is supported by previously unpublished photographs.

This second of two volumes on the North American B-25 Mitchell covers the late-WWII G through J, F-10, and PBJ variants of the famed US medium bomber. Among the many topics discussed are the Mitchell versions used by the US Navy and Marine Corps, as well as photo-recon and experimental types. B-25s in foreign wartime service are also shown, including those used in Poland, France, England, and Soviet Russia. A detailed chapter covers all types of armament used in the Mitchell, from guns and cannon of various calibers to ammunition used, including machine gun rounds, rockets, and bombs. A special section of the book features discussions on unique B-25 missions, events, and aircrew during WWII and in the postwar era, such as the April 1942 Doolittle Raid and the B-25 collision with the Empire State Building in July 1945. B-25 appearances in classic feature films such as Thirty Seconds over Tokyo and Catch-22 are also detailed.

The North American B-25 Mitchell is WWII's most heralded and versatile medium bomber. Volume 1 (of two) gives the reader a concise illustrated look at the A through D models and follows the bomber's genesis from the formation of the North American Company and its early steps toward the development of the NA-40, the first B-25. The continued evolution of the Mitchell from the A, B, C, and finally to the iconic D models is described in vintage photos. The production at the parent Inglewood, California, plant and then the Kansas City plant is illustrated, as are the important modification centres. The last half of the book covers the D model in many colour photos of the interior and exterior, from nose to tail and from wingtip to wingtip. The Wright R-2600 radial engine and Hamilton-Standard propeller are detailed, as are their associated systems. The Mitchell's markings and insignia changes are featured throughout.

In einem grossen Teil der ausgedehnten westlichen Literatur uber sowjetische Ange legenheiten ist in den letzten Jahren in zunehmendem Masse erkannt worden, dass ein Wandlungsprozess innerhalb des Sowjetsystems im Gange ist. In der Politik, Diplomatie, Wirtschaft, Erziehung, Kultur, der Wissenschaft und in militarischen Dingen - um nur einige Gebiete zu nennen - hat es Zeichen der Wandlung und der Anpassung an neue Gegebenheiten gegeben, als das Sowjetsystem aus der Stalin Ara in diejenige Chruschtschows uberging. Gewiss sind sich westliche Beobachter der sowjetischen Verhaltnisse in keiner Weise einig uber die Natur dieses Wand lungsprozesses oder die Richtung, die er nimmt. Man kann sehr verschiedene An sichten uber gewisse grundlegende Fragen finden. So wird beispielsweise die Auffassung vertreten, dass die Sowjetunion sich allmah lich zu einer Gesellschaftsform entwickelt, die in vielen grundlegenden Gesichts punkten jenen modernen Gesellschaftsformen ahnlich ist, wie sie in der westlichen Welt durch die Phanomene, die die Industrialisierung und Verstadterung beglei teten, hervorgerufen wurden. Diese Theorie der Angleichung wird von einer anderen verworfen, derzufolge sich das sowjetische System auf eigene 'Veise - sui generis - nach Grundsatzen fortentwickelt, die eine Verschmelzung mit der west lichen Welt zu einer gemeinsamen politischen und sozio-okonomischen Form un wahrscheinlich machen."
