The "model of peace" was the pinnacle of the honeymoon period between China and the United States, and in 1987 the two sides signed a contract to export equipment to China that could improve 55 sorties of J-8II. for a total of $550 million.

Two J-8IIs were delivered to the United States in early 1989, where they were evaluated and improved by U.S. personnel.

The U.S. side has a strong test flight force, using the 6510 squadron of the "Air Force Flight Test Center" (AirForceFlight Test Center) at Edwards Base.

The director of the U.S. flight test program is a veteran test pilot with 5,700 flight hours and has written textbooks for the U.S. military flight school.

At the same time, about 20 Chinese technicians went to the Grumman factory on Long Island in New York and Dayton Air Force Base for training and study.

However, after 1989, for well-known reasons, the short honeymoon period in the history of Sino-US relations ended, and the "model of peace" project finally died.

But this unfinished plan has had a profound impact on China's aviation industry.

China's aviation technicians have earnestly learned the advanced technology of US equipment and military enterprise personnel, and more importantly, they have profoundly experienced the integrity, developability, and foresight of Western advanced aviation technology.

Although this attempt did not produce direct results, it further clarified the direction and path for China's fighter technology to catch up with the world's first-class level.

Shortly after the cancellation of Sino-US cooperation, the Chinese Air Force's indicators for the J-8II. improved fighter have far exceeded the level of "model of peace", and a number of improved models such as the J-8II.M have been developed.

The most important of these is the development of an integrated fire control system, which is aimed at fulfilling the unfinished task of the "model of peace".

The new J-8II modification has finally reached a level close to that of a third-generation fighter through a series of improvements such as pulse-Doppler radar, digital integrated fire control system, air refueling technology, combined self-defense electronic countermeasure system, new plug-in system, reliability and maintainability improvements, and aerodynamic design.

In terms of radar, although China has not been able to obtain the original number of APG-66 radars, this radar has been adopted by many countries, and it is not difficult for China to study and learn from it, and Russia's Zuk radar is the standard equipment for export of the J-8II.M model.

At the same time, through the long-term efforts of China's scientific researchers, great progress has been made in the above-mentioned aspects, as well as medium-range air-to-air missiles, air refueling technology, inertial navigation/GPS integrated navigation technology, high-speed optical fiber bus and other fields.

These are areas that have never been touched by the "model of peace" and are of great significance.

All in all, the "model of peace" is an important turning point in the development of China's fighter technology, with far-reaching implications.

During the same period, the design of the J-10 fighter was based on Western standards, becoming China's first self-developed third-generation fighter in the true sense.

To a certain extent, the advanced equipment given by the United States is not the most cherished thing.

The in-depth experience of Chinese aviation engineers in the advanced military design and production ideas and systems of the West is the biggest gain of this international cooperation.

The Peace Model Program ran through a short honeymoon period in the history of U.S.-China relations, during which China imported a large number of advanced electromechanical equipment from the West, such as LM2500 gas turbines, Black Hawk helicopters, advanced gun-sighting radars, etc., to broaden the horizons of China's scientific research work, which had been stagnant due to cultural catastrophe.

On this basis, the military industry has made great strides from imitation to innovation, narrowing the gap with the world's advanced level.

After the collapse of the Soviet Union, most of the many promises made by the West to the Russians became bubbles, and China and Russia began to get closer.

At the same time as the introduction of the Su-27, China also began joint research and development work on some weapons and equipment, including the FC-1 and J-8IIM.

The J-8IIM can be regarded as an export model of the J-8II improved version with improved medium-range interception and ground attack capabilities. It is not clear whether the J-8II improved fire control radar is self-developed equipment (the general view is that the radar used is the "Beetle"-8II), but the "Beetle"-8II on the J-8IIM is indeed a fairly excellent multi-functional radar, which not only enables the J-8IIM to achieve over-the-horizon air combat that can deal with two air targets at the same time, but also to carry out precise attacks on targets on the ground or on the sea (HNA's J-8II can carry air-to-ship missiles to attack sea targets).

The J-8II improved version of the medium-range interception capability and ground attack capability was completed in 1995, and the J-8II in service was also modified later.

At this time, it was only five years before the termination of the "Peace Model" program, and the performance of the J-8II at this time also greatly exceeded the level that the "Peace Model" program could achieve.

Historically, the core of the Peace Model Program was mainly based on the J-8II fighter being developed by the 601 Institute, but this time the Americans suddenly came to Rongcheng to investigate, but Yang Weining had a different mind.

However, on the surface, Yang Weining did not show any special expression, and discussed with Lu Wenjun for most of the day, and roughly determined how to deal with the US aviation industry delegation.

In the next two days, the entire Rongcheng Aircraft Factory and the 611 Institute were mobilized to carry out various cleanings in preparation for the arrival of the Americans.

According to the original plan, Yang Weining began to train Rongfei's aeronautical engineers in AUTOCAD.

……

At three o'clock in the afternoon of October 9, 1982, not long after the National Day, a blue-and-white painted Y-8 medium transport plane belonging to the Chinese Air Force slowly landed at Huangtianba Airport.

The hatch opened, and the first to step out of the cabin was a tall and heroic middle-aged man, the man was wearing a grass-green khaki military uniform, a liberation cap, a red five-star cockade and a red collar badge.

He was followed by five blonde foreigners, four of whom wore suits and ties, and the last one was dressed in an American-style military uniform with the rank of colonel in the Air Force.

Tu Kai, Lu Wenjun, Li Weikang and others, who had been waiting at the airport for a long time, hurriedly greeted them, shook hands with the man who was beating their heads with a smile and said, "Director Yang, guests from the United States, welcome to the Rongcheng Aircraft Factory. ”

Yang Zhenguo, Tu Kai, and Lu Wenjun shook hands one by one, and said with a smile: "Lao Tu, Lao Lu, we meet again, let me introduce to you, this is Mr. Hugh Robert, senior vice president of Grumman in the United States, Mr. Edward Williams, deputy chief engineer of Boeing, Mr. Romain Rohdes, senior engineer of Lockheed, Mr. Cahill, senior vice president of Raytheon, and Colonel Stephen Harper, US military attache in China. ”

Tu Kai and Lu Wenjun smiled and shook hands with the members of the US aviation industry delegation one by one, welcomed their arrival, and after greeting each other, the group took a ride to the Rongfei Guest House.
