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 Using many formerly-classified documents from his large microfilm collection, William Wolf presents their previously-unpublished history.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In the end, the YB-40 participated in only 14 lackluster operational service test missions during mid-1943 before being withdrawn from service.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.

Packed with never-before-seen photos, plans and meticulous new digital artwork, this is the first history of the USAAF's futuristic World War II prototype interceptor, the XP-67 "Moonbat".The series of X-planes that sprang from the US Army's Request for Data R40C, focused on high-altitude, high-speed, long-range bomber interceptors. Among these aircraft was the McDonnell Aircraft Company's first ever clean sheet design, the XP67. Its futuristic lines promised performance that it was ultimately unable to deliver, but development was still underway when disaster struck. Just before Army performance demonstration flights were scheduled to begin, an engine fire destroyed the only XP-67 prototype, leaving a host of unanswered questions about what might have been, and leading to decades of continuing fascination with the XP-67 among aviation buffs and aircraft modelers.The authors of this book have uncovered new sources of information and a wealth of photographs and line drawings that document not just the XP-67 but also its immediate precursors within the McDonnell Aircraft design community, as well as alternative configurations for unbuilt variants aimed at different missions. Packed with unpublished photos of all stages of construction including key airframe changes made after initial flight tests, showing in detail how the final configuration was evolved, this volume finally provides clear focus on a story that has long been shrouded in mystery.

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.

At the dawn of the supersonic jet age, aircraft designers were forced to devise radical new planforms that suited the new power of the jet engine. One of the most successful was the delta wing. Although Gloster produced the delta wing Javelin, and Boulton Paul -its P.111 research aircraft - Fairey and Avro were the champions of the delta in Britain. Meanwhile in America, with the exception of Douglas's Navy jet fighter programmes, Convair largely had the delta wing to itself. These development lines, one on each side of the Atlantic, had essentially the same objective - to produce high-­speed fighter aircraft. In Britain, the Fairey Delta 2 went on to break the World Air Speed Record in spectacular fashion, but it failed to win a production order. In contrast Convair received major orders for two jet fighter types and one jet bomber. At the same time, the British Avro company built the 707 family of research aircraft, which led to the famous Vulcan, to show how the delta wing could be adopted for a highly successful subsonic bomber. This book examines the development of the delta wing in Britain and America, and the way in which experimental aircraft like the Fairey Deltas proved their potential and versatility. In Britain it covers the Fairey Delta 1 and Fairey Delta 2, the proposed Fairey Delta Rocket Fighter and huge Delta 3 long range interceptor, and the Avro 707. On the American side, it examines the Convair XF-92 and XF-92A, the development of the Delta Dagger/Delta Dart family, and the Convair Sea Dart - the world's only supersonic seaplane.

An authoritative new history and analysis of the Wright Brothers'' pioneering aircraft, from their triumph in 1903, through their string of achievements in the next decade, to their eclipse in the 1910s.Orville and Wilbur Wright, two bicycle-making brothers from Dayton, Ohio, secured their place as the most famous names in aviation history when, on December 17, 1903, they made the first powered, controlled, and sustained heavier-than-air flight. But their success over the cold and windswept Carolina dunes that day has overshadowed their many other accomplishments before and after that historic flight. The Wrights'' progression from theory to analysis to ground-testing components and wing shapes, and to then flight-testing kites, gliders, and their first powered aeroplane, marked the world''s first successful ΓÇ£X-PlaneΓÇ¥ research and development program. They established a template all subsequent aircraft have followed, one still relevant in the era of hypersonic flight and drone research.This book traces the Wright Brothers'' story, from their first success on that cold December day throughout their glory years to their eventual eclipse by other aviators. It explores in detail the process that lead them to their pioneering craft and their many subsequent achievements over the following years, and highlights their enduring importance in the age of modern flight.

This title is a detailed, illustrated guide to the Douglas D-558, the ground-breaking US Navy research aircraft which became the first aircraft to break Mach 2, and paved the way for America's Cold War "Century Series" fighters.The six Douglas D-558 research aircraft, built as two variants, were produced for a US Navy and NACA collaborative project to investigate flight in the high subsonic and supersonic regimes and to develop means of coping with the dangerous phenomena of compressibility and pitch-up which had caused many accidents to early jets. Wind tunnels could not provide the necessary data so pilots had to risk their safety in experimental aircraft which, for their time, achieved phenomenal performance. Both series of D-558 were well-designed, strong and efficient aircraft which enabled test pilots to tackle the unknown in comparative safety. Though delayed by their innovative, troublesome power-plants and limited by the cost of their air-launched sorties, they went well beyond their original Mach 1 speed objective and continued to generate information that provided design solutions for a whole generation of supersonic combat aircraft. Although the final stage of the D-55 program, the USN's "militarized" D-558-3, never happened, the Navy was able to apply the lessons of the program to its much more practical combat types such as the F8U Crusader and F3H Demon. Supported by full-color artwork including three-view plates of the two D-558 models and a technical view of the D-2 cockpit, this authoritative text offers a comprehensive guide to the record-breaking Navy research craft.

From the Heinkel He 178 to the Caproni Camini N.1, this is the authoritative illustrated guide to the revolutionary aircraft that led to start of the military jet age.While World War II raged, pioneering aircraft and engine designers were busy developing the world''s first practical jet-powered research aircraft to test and prove the new technology. This book examines the aircraft that paved the way for Germany''s Me 262 and Britain''s Meteor - the world''s first jet fighters. Throughout the war, Germany, Italy, and Britain engaged in top-secret jet programs as they raced to develop the airpower of the future. Various experimental aircraft were trialed in order to achieve the goal of producing an effective engine and fighter that could harness the potential of the jet power. These included the German Heinkel He 178 research aircraft and Heinkel He 280 jet fighter prototype, the famed British E.28/39 research aircraft built by Gloster Aircraft as well as the stillborn E.5/42 fighter and E.1/44 Ace fighter prototype, and finally the remarkable Italian Caproni-Campini N.1/CC 2 research aircraft.Illustrated throughout with full-color artwork and rare photographs, this fascinating study examines the fore-runners to the military jet age.

The Dornier Do 335 was conceived as a high-speed, all-weather fighter, and represented the pinnacle of piston-engined aircraft design. The Do 335 was a big aircraft, weighing just over 10,000kg when laden with fuel, equipment, and pilot, yet powered by two Daimler-Benz DB 603 engines, it was capable of reaching a maximum speed of 750km/h at 6400 meters, making it the fastest piston engine aircraft produced in Germany during World War II.Some forty aircraft were built between late 1943 and the end of the war, and it was intended to deploy the type as a day fighter, bomber, night fighter, bad weather interceptor, and reconnaissance aircraft, all of which were intended to incorporate the latest armament, bomb sights, communications, and radar equipment, as well as an ejector seat. Featuring archive photography and specially commissioned artwork, this is the full story of the aircraft that the Luftwaffe hoped would turn the tide of the war.

The Bachem Ba 349 Natter was a secretive, vertical take-off, single-seat rocket interceptor intended to offer high-speed defense of key targets. This radical aircraft offered Luftwaffe an inexpensive means with which to intercept and attack Allied heavy bombers using a vertically-launched, semi-expendable machine built of wood and armed with a nose-mounted "honeycomb" battery of spin-stabilized air-to-air rockets, as well as cannon armament. Launched vertically at 36,000 feet per minute, the pilot was expected to fly within range of the enemy bombers, fire his rockets at them, ram another bomber, eject, and parachute to the ground.Illustrated with contemporary photographs and stunning commissioned artwork, this study examines this inventive yet ultimately unsuccessful attempt by the Luftwaffe to defend against the tide of Allied aircraft that was bombing German cities into the ground.

Of the many futuristic military aircraft concepts created in the 1950s the North American XB-70 still stands out as the most awe-inspiring. With its huge, white partially-folding delta wing, its fuselage resembling a striking cobra and its extraordinary performance, it was one of the foremost technological achievements of the 20th Century. A strategic bomber built to outrun any Soviet fighter jet, it could reach Mach 3 with a full nuclear payload - as fast as the legendary SR-71 Blackbird but more than three times the size. However, its role as a nuclear bomber was limited after the introduction of Intercontinental Ballistic Missiles, and defence cuts eventually led to the project being scrapped in the mid-1960s.The Valkyrie had a brief, costly decade of life but it proved the continuing value of developing manned bombers. However, almost half a century after the XB-70 its predecessor, the B-52, continues in service. Using full colour artwork and rigorous analysis, this is the complete story of the ultimate US Cold War military X-plane.

Even before the spectacular success of its X-1 rocket-powered aircraft in breaking the 'sound barrier', the adventurous Bell Aircraft Corporation was already pushing ahead with a parallel project to build a second aircraft capable of far higher speeds. The X-2 (or Model 52) explored the equally uncertain technology of swept-back wings. Now common in modern conventional fighter aircraft, the Bell X-2 was revolutionary in using this type of airframe to probe Mach 3 and research the effects of extreme aerodynamic friction heat on airframes. Although both X-2s were destroyed in crashes after only 20 flights, killing two test pilots, the knowledge gained from the programme was invaluable in developing aircraft that could safely fly at such speeds. Using stunning artwork and historical photographs, this is the story of the plane that ultimately made the Lockheed Blackbird and Concorde possible.

The revolutionary X-15 remains the fastest manned aircraft ever to fly. Built in in the two decades following World War II, it was the most successful of the high-speed X-planes. The only recently broken ''sound barrier'' was smashed completely by the X-15, which could hit Mach 6.7 and soar to altitudes above 350,000ft, beyond the edge of space. Several pilots qualified as astronauts by flying above 50 miles altitude in the X-15, including Neil Armstrong, the first man on the Moon. The three X-15s made 199 flights, testing new technologies and techniques which greatly eased America''s entry into manned space travel, and made the Apollo missions and Space Shuttle viable propositions. With historical photographs and stunning digital artwork, this is the story of arguably the greatest of the X-Planes.

The TSR2 is one of the greatest "what-if" aircraft of the Cold War, whose cancellation still generates anger and controversy among aviation fans. It was a magnificent, cutting-edge aircraft, one of the most striking of the Cold War, but fell victim to cost overruns, overambitious requirements, and politics. Its scrapping marked the point when Britain''s aerospace industry could no longer build world-class aircraft independently. After the demise of TSR2 the RAF''s future jets would be modified US aircraft like the Phantom and pan-European collaborations like Tornado and Typhoon.In this book the eminent air power analyst and ex-Vulcan bomber pilot Andrew Brookes takes a fresh, hard-headed look at the TSR2 project, telling the story of its development, short career, and cancellation, and evaluating how it would have performed in Cold War strike roles as well as in the recent wars in the Middle East.

As Europe plunged into World War II, Hitler ordered the development of a hi-tech secret weapon capable of taking the war across the Atlantic - the Messerschmitt Me 264. Chosen from designs for an 'Amerika Bomber' tendered by Messerschmitt, Junkers and Focke-Wulf, this ultra-long-range aircraft would be capable of attacking cities in the United States. Just one month before the attack on Pearl Harbor and the American entry into World War II Hitler was promising, privately, to wage a 'new war' against the USA after his victories in Europe. Dazzling digital artwork and 50 rare archive photographs perfectly complement the detailed analysis offered by Robert Forsyth as he examines the development, intended role and influence of the aircraft that Hitler planned to use to bomb New York City.

In 1947, no one knew if it was possible to break the 'sound barrier'. The Bell X-1 was the tiny, rocket-powered craft that finally broke it. It was the result of innovative designers and engineers turning their attention from the pioneering jets of World War II to a new task - an aircraft designed purely to fly faster than sound. Legendary pilots rallied to the cause, with World War II ace Chuck Yeager piloting the X-1 when it finally achieved supersonic flight in 1947, the first manned craft to reach such speeds. With historical photographs and meticulously researched digital art, Peter Davies traces the whole career of the pioneering Bell X-1, from its early development through to the influence it had on military and civilian jets in the second half of the 20th century.
