North American XB-70 VALKYRIE
In 1954 the USAF began the development of a supersonic bomber that would be capable of penetrating Soviet anti-aircraft defenses thanks to its speed and high flight altitude. This is how the North American XB-70 Valkyrie was born, a very advanced aircraft that unfortunately did not enter service despite more than 15 years of work and a gigantic amount of money spent. The high cost of the project, as well as the proliferation and improvement of ICBM missiles, put an end to the dream of the “Mach 3 strategic bomber”.
