Valkyrie - The North American XB-70 - The USA's Ill-Fated Supersonic Heavy Bomber (Simons Graham M.)(Paperback) - diskuze

During the 1950s, at the time Elvis Presley was rocking the world with Hound Dog and the USA was aiming to become the world?s only superpower, plans were being drawn at North American Aviation in Southern California for an incredible Mach-3 strategic bomber. The concept was born as a result of General Curtis LeMay?s desire for a heavy bomber with the weapon load and range of the subsonic B-52 and a top speed in excess of the supersonic medium bomber, the B-58 Hustler. If LeMay?s plans came to fruition there would be 250 Valkyries in the air; it would be the pinnacle of his quest for the ultimate strategic bomber operated by America?s Strategic Air Command. The design was a leap into the future that pushed the envelope in terms of exotic materials, avionics and power plants. However, in April 1961, Defense Secretary McNamara stopped the production go-ahead for the B-70 on grounds of rapid cost escalation and the USSR?s newfound ability of destroying aircraft at extremely high altitude by either missiles or the new Mig-25 fighter. Nevertheless, in 1963 plans for the production of three high-speed research aircraft were approved and construction proceeded. In September 1964 the first Valkyrie, now re-coded A/V-1 took to the air for the first time and in October went supersonic.This book is the most detailed description of the design, engineering and research that went into this astounding aircraft. It is full of unpublished details, photographs and firsthand accounts from those
