Recently, a group of satellites ** caused a stir on the network, revealing the striking appearance of the next generation of American strategic reconnaissance aircraft SR72. SR72 is a concept proposed by Lockheed Martin in 2007, and it is expected to become a strategically important stealth multi-purpose unmanned aircraft with powerful reconnaissance capabilities and diversified combat functions.
It is clear from the satellite** that the design of the SR72 is unusually unique, with a pronounced back bulge and a sweep angle much larger than that of ordinary supersonic aircraft, which seems to imply that it pursues the goal of extreme speed. According to reports, the SR72 has a maximum flight speed of Mach 6, exceeding the speed limit of most anti-aircraft missiles, and it is expected to be put into combat use around 2030.
The predecessor of the SR72 is the SR71 high-altitude supersonic strategic reconnaissance aircraft developed by the American Lockheed Martin company in the 60s of the last century, and the SR72 is an evolution on its basis. Compared with the SR71, the SR72 has made great strides in speed, technology, and combat capabilities, making it a formidable force on the battlefield of the future.
However, even powerful technology cannot hide the challenges faced by hypersonic vehicles. For example, for a hypersonic vehicle flying at a speed of more than Mach 3, the high temperature generated by the friction between the body and the air can cause it to burn or lose contact and crash, which is an extremely difficult problem. The United States has tried to carry out relevant tests through projects such as X51A, but the results achieved are not ideal, and technical bottlenecks and insufficient ground tests have become constraints.
At the same time, the development of our country in the field of hypersonic is also attracting attention. According to reports, China has developed the MD-22 hypersonic vehicle and successfully conducted relevant tests. The technical indicators of the MD-22 are very amazing, far surpassing the American SR71, showing China's leading position in the field of hypersonics.
However, despite the significant progress made in the research and development of hypersonic vehicles in China, there are still challenges in interception technology. At present, intercepting hypersonic vehicles is still a global problem, and it is difficult for traditional missile systems to accurately intercept such high-speed vehicles. Therefore, China is also actively developing new interception systems such as laser cannons to improve national defense capabilities.
To sum up, the emergence of hypersonic vehicles will greatly change the pattern of future wars, and the development of our country in this field will also make an important contribution to international peace. With the continuous progress and innovation of science and technology, we are confident that we will meet the challenges of the future and defend the interests and dignity of our country.
