The XB-70A, built by the North American Aviation (NAA) Los Angeles Division for the U.S. Air Force, was an experimental high-speed, delta-wing aircraft designed to fly at three times the speed of sound and higher than 70,000ft.

To survive an environment where sustained aerodynamic heating created aircraft skin temperatures ranging from 475 to 630 degrees Fahrenheit (246 to 332 degrees Celsius), NAA used titanium for 9 percent of the airplanes’ construction. To avoid using rare and expensive titanium, NAA came up with a high strength skin that could beat the heat by developing a steel honeycomb sandwich skin that was manufactured using brazing to join metal to metal, rather than welding. This technique later became widely used throughout the aerospace industry.

With a maximum takeoff weight of 542,000 pounds (245,847 kilograms), the XB-70 remains the largest and heaviest airplane ever to fly at Mach 3. A rugged landing gear, weighing more than 6 tons (5.4 tonnes) and consisting of 2 tons (1.8 tonnes) of wheels, tires and brakes supported the XB-70 on the ground. Each main gear had four wheels and the nose gear two. In a single stop, the XB-70 absorbed kinetic energy equivalent to that used to stop 800 medium-sized automobiles from a speed of about 100 mph (161 kph).
