What is the concept of ATF discussed by the representatives of American fighter manufacturers and the Air Force?

1982 10, most American fighter manufacturers and air force representatives met in Anaheim, California to discuss the concept of ATF. At this meeting, the concept of ATF basically took shape, which is very close to what we see today: this aircraft has been clearly defined as the next generation of air superiority fighters; Must have supersonic cruise capability; The operational radius is 600-800 nautical miles; It has the ability to take off and land on a runway of 2000 feet, so the engine needs to be equipped with a reverse thrust nozzle; The takeoff weight shall not exceed 60,000 pounds in air combat missions and 80,000 pounds in ground attack missions. Subsequently, the US Air Force issued a program requirement and began to enter the detailed research stage of ATF concept. 1983 in may, the CDI phase ended, and the air force released the final plan demand report. People may have noticed that none of the above ATF concepts mentioned stealth technology. In fact, stealth technology still belongs to the "black plan" at this time, and people who know it are quite limited. Although the US Air Force began to consider introducing stealth design into ATF in 1976, if we want to put forward this requirement in the ATF project that has not yet entered the confidentiality stage at that time, we will be forced to disclose a series of related black plans, including the top-secret "megatrend" plan, which the air force executives do not want to see.
