If you didn't know Lockheed Martin or Skunk Works, then just listen to the fighter jets this company had produced and you'd understand.
From the early U-2 reconnaissance aircraft to the SR-71 Blackbird reconnaissance aircraft—the first aircraft in human history to break the thermal barrier, fly at speeds exceeding Mach 3, and conduct reconnaissance above 20,000 meters—to the F-117 Nighthawk stealth attack aircraft, the F22 Raptor fighter jet, and the F35 Lightning fighter jet.
Just from the names of these groundbreaking technologies, one could tell how outrageously formidable this company was. That was why Skunk Works was so famous: this one company had practically dominated the entire strength of the U.S. Air Force.
As for this Stealth Fighter Jet, judging from the performance it had displayed so far, its flight speed, launch configuration, and other overall aspects surpassed the F22 and F35. In unmanned mode, both its flight ceiling and maneuverability could break past their limits.
As for why it had not yet broken the thermal barrier, they were probably still conducting temporary verification.
Its stealth capabilities were also absolutely insane. No one knew what kind of technology it used. After all, it was impossible for the F22 and F35 to fly near China's borders without being detected.
Unless it had incorporated a great deal of new groundbreaking technology, such as an entirely new Stealth Coating capable of absorbing radar waves.
A stealth fighter jet that could even deceive Microwave Radar was filled with far too many advanced technologies.
Even the United States itself had not announced this fighter jet. Neither America's allies nor any other country had captured images of it. Of course, that might also have been because its appearance resembled the F22 and F35. Even if it was occasionally photographed at high altitude, people would assume it
