In the 70s of the last century, Lockheed was developing a fighter codenamed H**e Blue, which is a radar stealth fighter, which was later known as the F-117 "Nightingale", but at that time this was a top-secret project, I don't know if it was intentional, this project was leaked to ** in the early 80s, but people do not know the specific information, only know that there is an advanced stealth fighter that can deflect radar waves in development, and it also installs exhaust cooling equipment, which can reduce infrared radiation.
By 1986, H**e Blue had attracted more widespread attention, and there was more and more speculation about it, with so-called inside information coming out, naming the fighter F-19, and then a game called "F-19 Stealth Fighter" appeared, in which players will play the role of pilots and fly fighter planes on different maps for different difficulty missions.
At that time, many rumors about the F-19 had a nose and an eye, and from the perspective of later generations, this information was a mixture of truth and falsehood, such as the use of radar absorbing coating, infrared suppression technology, and multi-faceted modeling of the fuselage, especially the cover picture of the "F-19 stealth fighter" game at that time, there was a frontal shadow of a fighter, which did look a little similar to the F-117.
On the whole, the F-19 may be a smoke bomb released by the United States at that time, and it was almost impossible to hide the project in the international environment of bipolar confrontation at that time, it involved too many resources, and the prototype must always be tested in the sky, since it can't be hidden, then simply release smoke to confuse the opponent, so that everyone is confused, the United States has never officially admitted the existence of the F-19.
The F-19 became a hot military topic for a while, and VSKYLABS launched a model specifically for it, and it quickly surpassed the previous most popular model of the USS Enterprise, which was the best-selling item in the company's history. VSKYLABS' model shows a single-seat, twin-engine stealth fighter with an inwardly inclined twin tail and a small front wing, and the company also gives some specific figures, such as the aircraft's top speed of 1Mach 2, with a maximum flight altitude of 53,000 feet (about 16,154 meters) and a maximum range of 1,400 miles (about 2,253 kilometers), the aircraft has a built-in magazine and can carry two AIM-9 "Sidewinder" air-to-air missiles and two air-to-surface cruise missiles.
On November 10, 1988, the U.S. Air Force announced the F-117A for the first time, which was an official denial of the F-19 stealth fighter, and its popularity quickly subsided, but today you can still buy the game "F-19 stealth fighter" from the online platform.
