With the continuous development of global technology, the importance of various advanced weapons and equipment in modern warfare is also increasing. aircraft carrier is a typical representative of it. It not only has a huge carrier-based aircraft formation, but also is equipped with corresponding auxiliary ships and firepower systems. The combat effectiveness of the aviation battle group at sea is very strong, and there are very few countries that can own aircraft carrier now. After all, it is difficult to build and expensive, and ordinary countries cannot afford it.
However, in addition to the killer such as aircraft carriers, there was previously a bomber that received widespread attention from the outside world. It is reported that the cost of this bomber can even be comparable to that of some small aircraft carriers, and its flight speed is also very excellent, and even most missiles cannot catch up with it. This kind of bomber is the XB70 "Valkyrie" announced by the United States in the last century. To this day, only the United States has completed the production and manufacturing of this kind of bomber.
It is reported that the flight speed of this bomber reaches supersonic speed, with the fastest being Mach 3. Therefore, it is not an exaggeration to say that it cannot catch up with missiles, but the truth. It was born during the Cold War. Its length was 59.74 meters, with a maximum take-off weight of 249 tons, and can carry 22.5 tons of nuclear bombs. The main reason is that the United States used it to crush the Soviet Union and create a deterrence in order to show its strong military power. Because of its excellent performance, this bomber quickly attracted widespread international attention as soon as it was announced.
"Vajra" bomber uses afterburner turbojet engines, and a total of 6 units are installed. Its flight altitude can reach about 21,500 meters. You should know that this is at supersonic speed. Once the war breaks out, the "Valkyrie" flew to your doorstep and you may not even see it. In the process of producing the XB70 bomber, the United States chose to consume a lot of resources and also used titanium as its fuselage material. The main purpose of this move was to solve the problem of the continuous increase in the surface temperature of the aircraft due to the rapid flight speed, and to ensure that the state of the fighter pilot and the fighter plane is not affected by high temperatures.
It is precisely because the materials used to manufacture aircraft are too expensive that the bomber cost 750 million US dollars, which would be equivalent to billions of dollars today. The cost is higher than some small medium-sized aircraft carriers , and with a flight speed of Mach 3, all missiles at that time were not even comparable to those of this type of bomber, so it was naturally difficult to strike it. It is worth mentioning that pilots will not be affected by high altitude without wearing flight suits on this fighter.
But in the end, this XB70 bomber was not used in actual combat. The reason for this situation was that in subsequent experiments, this model bomber had accidents many times, and even the driver died unexpectedly. In addition, with the continuous improvement of intercontinental ballistic missile technology in various countries, the flight speed of missiles has also developed significantly, some reaching Mach 20. It is already equipped to intercept and destroy such bombers.
. When the United States launches nuclear strike against and other operations, it no longer needs to rely on bombers to carry out the operation. At the same time, due to the high cost of the fighter itself, the "Valkyrie" bomber ultimately faced retirement without conducting actual combat.
