What is the performance of the Leona hypersonic reconnaissance plane, one of the legends in American military circles?

SR-71 that served in 196s? Blackbird? It is the legendary existence of the US Air Force. With its advanced cruise speed of Mach 3 across the ages, for? Blackbird? Generally speaking, you can do whatever you want, because no air defense missile can intercept it, many times? Going deep alone? The investigation in Soviet airspace has already caused headaches for all countries.

in fact, there is another legend in the U.S. air force, that is, SR-71? Blackbird? Subsequent models of:? Leona? Hypersonic strategic reconnaissance aircraft (Aurora), or known as? Aurora? , the model is SR-91? Aurora? , but its sum? Blackbird? On the continuity of research and development, many military enthusiasts prefer to call it? Super blackbird? Or? Son of a blackbird? . In 27, the US Air Force and the Defense Advanced Research Projects Agency signed a memorandum of understanding, which slightly unveiled some SR-91? Aurora? The veil, expected? Aurora? The maximum flight speed can reach or exceed Mach 6, and cruise at the top of the stratosphere close to 4, meters.

but before 27, the U.S. military did not recognize SR-91? Aurora? The existence of this hypersonic reconnaissance plane, although a large number of aerial photographers have photographed the suspected SR-91? Aurora? Photos, and according to the fuzzy photos imagine? Super blackbird? Flight concept map. SR-91? Aurora? The internal number of the military is also CP-14. As early as the 198s, the US Air Force has cooperated with NASA to launch the project. Aurora? The research scheme was designed, although it did not achieve much practical results at that time, but it was also SR-91? Aurora? Made a certain technical reserve.

suspected? Aurora? The photo was first exposed in 1985, and in the 1986 budget report of the United States submitted in February 1985, it was in? Strategic reconnaissance? In the air force classification project, it first appeared? Aurora? Words, and attracted great attention from the media. Although the U.S. government made it clear that there is no such thing as? Aurora? Hypersonic reconnaissance aircraft project, the budget is only used for the breakthrough of conventional reconnaissance technology, but only in fiscal year 1986? Aurora? It's doubtful that one account for $2.2 billion. It seems that in order to hide people's eyes and ears, the budget report for fiscal year 1987 did not appear? Aurora? However, after several years of statistics, from the late 198s to the early 199s, nearly $1 billion of the Air Force procurement budget mysteriously disappeared, which has not been decrypted until now.

Since August p>1989, residents of Edward Air Force Base in California and some areas in Nevada have frequently heard loud explosions. Even houses 25 kilometers away from the place where the sound was generated are shaking. This huge sound wave impact is scientifically called? Acoustic shock? The loud noise in the western States of the United States will even make the seismic observers of the Seismological Bureau perceive the signal. Except for the sound, similar? Sausage-like The knot-shaped condensed tail smoke also often appears in the sky after the roar, so it is considered as? Aurora? Evidence of a flight test.

according to military experts, SR-91? Aurora? Using the latest engine technology of the US Air Force? The pulse aero-engine can make the fighter run at an amazing Mach 6, plus a flying height of 4 kilometers and a brand-new stealth technology for anti-radar detection. Aurora? The performance of has been beyond the sky, jilt? Senior? SR-71 has many streets, and there is no air defense weapon system in the world that can intercept hypersonic fighters at such a high altitude. May 214,? Aurora? Even honored to board a ploughing channel in China, through being filmed? Mysterious triangle fighter? To analyze. A retired colonel in the United States was asked? Aurora? At the time, everyone said bluntly? American technology makes us look like aliens. When using SR-71, the enemy can know where we are but can't touch us, but the enemy won't even know where we are because of SR-91. ?
