This is a thing that does not exist, but it is the hope of many people, but there is no need to be disappointed in it!
Old chance of winning
The continuous knock engine developed by the scientific research team of the School of Aeronautics and Astronautics of Tsinghua University has been successfully developed after years of arduous efforts, marking the transcendent development of China's aero engine. Aircraft equipped with this kind of engine can fly at a speed of more than Mach 6, and existing air defense missiles can basically be used to it. It is reported that there is currently no other country in the world except my country to successfully develop such advanced engines.

From this we can see that our scientific research has long focused on the most advanced and transcendent things, rather than the catch-up style of the past.
However, many people's thinking seems to be still in the past and have no real understanding and acceptance of such a new reality. The most obvious manifestation is that many people are still obsessed with and are looking forward to the emergence of "flying wing stealth bombers".
can be said that if we invested our scientific research forces and resources into the "flying wing-style strategic hidden bombing", then the reality would have been that we would have had a huge fleet, not a "first flight". But decision makers are aiming at surpassing or ahead, not about what others have done, or even making "flying wing-like hidden bombardment".

may be because I have experienced it for many years in this field. For many years, I have been paying attention to the field of aircraft, but I have never found any official authoritative information that is developing "flying wing-like hidden bombing". The reason why rumors are rampant is that some people use specious information to piece together and speculate false conclusions made up by their imagination. It is wise for the official not to refute the rumors, because this will distract the attention to truly important equipment without pouring cold water on enthusiasts who care about national defense.
