The North American Aviation XB-70 Valkyrie is a retired prototype version of the planned B-70 nuclear -armed, deep-penetration supersonic strategic bomber for the United States Air Force Strategic Air Command. The second XB-70A (AV-2) flew multiple times at Mach 3, including a sustained, 32-minute, Mach 3 flight in May 1966. Valkyrie AV-2 was lost in June 1966 after an F-104 collided with it in mid-air. F-104 pilot Joe Walker (NASA) and XB-70A copilot Maj Carl Cross (USAF) died. North American pilot Al White ejected from the XB-70A, but was badly.
North American XB70 Valkyrie
The North American Aviation XB-70 Valkyrie was the prototype version of the planned B-70 nuclear-armed, deep-penetration supersonic strategic bomber for the United States Air Force. The XB-70 Valkyrie, with a planned cruise speed of Mach 3 and operating altitude of 70,000 feet, was to be the ultimate high-altitude, high-speed manned strategic bomber. Events, however, would cause it to play a far different role in the history of aviation. The iconic North American XB-70 Valkyrie was the most ambitious super-bomber project of the Cold War. The massive six-engine bomber was slated to be the ultimate American high-altitude,. Photo: USAF Summary The North American XB-70 Valkyrie, designed as the bomber of the future, flew at three times the speed of sound. However, effective Soviet surface-to-air missiles made the Valkyrie vulnerable at any altitude. After extensive analysis, the USAF found that the XB-70 performed similarly to the B-52 under such conditions.

The XB-70 Valkyrie, with a planned cruise speed of Mach 3 and operating altitude of 70,000 feet, was to be the ultimate high-altitude, high-speed manned strategic bomber.. died in the accident. North American test pilot Al White ejected from the XB-70 in his escape capsule, but received serious injuries in the process. Co-pilot Maj. Carl. XB-70: This Ride of the Valkyries Got Cut Short Alas, for all promise the XB-70 held on-paper, it wasn't meant to be, as the plane was overcome by events (OBE). First and foremost, there.
The nose and other leading-edge parts of the Valkyrie rose to 330 degrees Celsius (625 degrees Fahrenheit) at Mach 3 speeds while the rest of the airframe remained at 232 degrees Celsius (450 degrees Fahrenheit). To withstand these extreme temperatures, the XB-70 was built of stainless steel honeycomb panels and titanium. The North American XB-70 Valkyrie was a long-range bomber that could reach deep into Soviet airspace, but it was compromised by a declining defense budget and improved surface-to-air missiles. by Walter J. Boyne 11/10/2009 One of two XB-70A Valkyries built takes off, escorted by a TB-58 chase plane.
XB70 Valkyrie Bomber Engineering Channel
The North American XB-70 Valkyrie was the largest and fastest bomber ever built by the United States, but the massive six-engine Mach 3.0-capable jet never entered production. XB-70 Valkyrie. Strategic Bomber Prototype. High-Speed Research Aircraft. DESCRIPTION: The B-70 bomber program resulted from an Air Force requirement for a high-speed, high-altitude strategic bomber to replace the B-52. North American engineers utilized NACA studies dealing with optimum Mach 3-6 configurations to develop the winning B-70 design.
