In the history of mankind, there was such a bomber. The cost of a bomber was comparable to the aircraft carrier . It was equipped with 6 huge engines and was a 250-ton supersonic long-range bomber. At that time, it used The most advanced aviation technology that mankind has mastered, it should be a bomber that can shine in the military world, but in the end it was hastily dismounted, one crashed, and the other was brought closer to the museum. This is the American Valkyrie bomber.

To this day, the Valkyrie bomber is still talked about by people, because it is the world's first long-range strategic bomber that can fly at supersonic speed, and it is also the fastest bomber so far. It can reach Mach 3, which is faster than some current missiles. However, the Valkyrie bomber was born in the 1970s. You can imagine how sci-fi it was. When people saw this bomber for the first time at that time, they would most likely think It is a UFO that visits the earth.

The Valkyrie bomber has a very high degree of recognition. It has a slender body, a very modern aerodynamic shape design, the iconic delta wing layout, and the canard layout design on the nose. This bomber has a crew of 4 and has a maximum takeoff weight of 249.4 tons, which is equivalent to a body size of 250 tons. It can carry 136 tons of fuel. It once set a flight record of Mach 3 at an altitude of 21,500 meters. We all know that advanced weapons are born for a reason, so Why does the United States develop this bomber?

Since the development of jet fighters by Germany at the end of World War II , the development of aircraft has begun to undergo major changes. After the war, various countries began to develop jet fighters, making fighter jets faster and faster. At that time, the speed of bombers had obviously lagged behind Fighters, being slow in the air, mean they will be beaten. The U.S. military has been thinking hard to allow bombers to successfully fly deep into the former Soviet Union to carry out bombing missions. Therefore, it decided to develop a bomber that is faster than fighter jets and break through the capabilities of former Soviet fighter jets. Intercept.

Therefore, the XB70 fighter was hurriedly put on the agenda. The overall layout of this bomber is a canard, no horizontal tail and a large delta wing , with 2 vertical tails . When flying at supersonic speeds at high altitudes, the external temperature can reached 400 degrees Celsius, so instead of using traditional aluminum alloy profiles for construction, expensive titanium alloy profiles were developed and used, which led to a further increase in the cost of the aircraft. After conversion, the cost of such a bomber can purchase 300 fighter jets at the same time. , or 1 US aircraft carrier.

In modern times, an aircraft carrier costs 30 billion, and it is very luxurious to build a bomber. Even the B2 bomber is not so expensive. In the end, during a flight show, the XB70 bomber and an accompanying The fighter jets collided and crashed, and were subsequently attacked and criticized by a large number of opposition figures, saying that this bomber was not practical at all. In addition, the former Soviet Union had developed anti-aircraft missiles at the time and was also developing MiG-25 interceptors. Therefore, the XB70 was regarded as a human The legend in aviation history has withdrawn from the stage of history.
