Meet The Supersonic Bomber XB-70 Valkyrie That Reaches 3x The Speed Of Sound And Revolutionizes Aviation
Today I will talk about a true aviation legend: the supersonic bomber XB-70 Valkyrie. This monster of the skies was designed by the United States in the 1950s and 60s and was capable of reaching three times the speed of sound. Let’s understand how it achieved this incredible feat and why it is so special!
The XB-70 Valkyrie was created to replace the B-52 bomber. The idea was to have an intercontinental nuclear bomber that could fly at supersonic speeds. However, with the advancement of intercontinental ballistic missiles and ground-to-air missile defense systems, the role of the Valkyrie changed. It ended up being used by NASA for experiments in supersonic speeds, helping to develop technologies for future supersonic passenger transport aircraft.
Innovations Of The Supersonic Bomber XB-70 Valkyrie
This giant airplane was 56.6 meters long, with a wingspan of 32 meters and an incredible height of 9.14 meters. It weighed up to 246 tons at takeoff and could reach Mach 3 at an altitude of 23 km, with a range of 6,900 km. For its time, this was something out of this world!

Surfing On A Shock Wave
What made the supersonic bomber XB-70 Valkyrie so special was its ability to “surf” on its own shock wave. Up to Mach 0.9, the wing tips operated at 0°. When it reached Mach 1.4, they folded to 25°, and from there, up to Mach 3, they stayed at 65°. This maneuver increased lift by 30%, allowing for more efficient flight.
By folding the wing tips, the XB-70 created a high-pressure zone that increased lift. This allowed it to fly at a lower angle of attack, reducing drag. This advanced technology made the Valkyrie a true pioneer in supersonic aviation.
The Legacy Of The XB-70 Valkyrie
Unfortunately, only two prototypes of the XB-70 Valkyrie were built, with the third being canceled. In 1966, one of the prototypes was destroyed in an accident. Despite this, the Valkyrie project left an important legacy for aviation. Its ability to use shock waves to increase lift influenced the development of hypersonic missiles and other advanced technologies.
Today, the concept of “Wave Rider,” used by the Valkyrie, is back with hypersonic missiles such as the Boeing X-51 and the Brazilian 14-X. Even though the project for the supersonic bomber XB-70 Valkyrie has been concluded, its impact on engineering and aviation continues to be felt.
The XB-70 Valkyrie was not just an airplane; it was a revolution in the skies. It showed what was possible with the technology of the time and paved the way for future innovations in aviation.
Brincadeira.. não tem como chamar de mentirosa uma matéria dessas. Mas de BRINCADEIRA. O Walkiria , com esse nome mesmo, foi feito pela União Soviética na guerra fria😂, e está em um museu em Moscou. A mentira assim tem um nível tão descarado que não pode ser chamada de fake. Credo
Tem fontes pra provar o que diz????
Mais esse avião não foram os Estados Unidos que inventaram e sim os Soviéticos
…Teu “oi” !!!
Vai estudar, por favor
E cadê ele? Seria espetacular,mas hoje teria que ser hipersonico,supersônico está ultrapassado.
Está em um museu, nos EUA
