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.

In flight, the XB-70 could lower the outer wing sections 25 degrees for flying from 300 knots to Mach 1.4, or a severe 65 degrees for speeds from Mach 1.4 to Mach 3+. Measuring just a bit over 20 feet at the trailing edge, these wingtips represent the …

The hottest portions of the Valkyrie, her nose and horizontal splitter, reached a temperature of only 625 degrees during Mach 3 flight, with the majority of the XB-70's skin at a temperature of just 450 degrees!

The XB-70 is a large, high-performance, delta-wing airplane designed for cruise flight at Mach 3. A three-view drawing of the airplane in the landing configuration is

The XB-70 pilots were frequently assisted by callouts from escort pilots that indicated height above the runway before touchdown. This paper presents data obtained from the first 48 landings of the XB-70-1 airplane. Included are main-gear and nose-gear landing loads , …

Including the pitot tube on the nose, the aircraft was 185.83 ft (56.69 m) long, 30.75 ft (9.38 m) high and weighed a staggering 542 000 lb (246 365 kg) at maximum takeoff weight.
