As early as when he cooperated with NASA to develop the "GPS" global satellite positioning system, Yang Weiping had already drawn elite soldiers from the Tiangong Shi Yàn Room and major scientific research units in China to start the research and development of the "Beidou Global Satellite Navigation and Positioning System".

The construction of Beidou satellite is an important part of OUCC's strategic undertakings. Of course, national defense and security are the most important reasons for the construction of the Beidou system.

In such an important battlefield of global geographic information, OUCC must master a high-end satellite positioning and navigation system with completely independent intellectual property rights and products.

Although it is said that the civilian use of GPS is free in the Eastern Union, if the US imperialists shut down or use its "SA policy" to manipulate GPS, it will undoubtedly be fatal to countries that rely on GPS at that time.

Beidou satellite started in 1979 and achieved regional coverage capability in 1985, which can provide services for Asian countries, and is well received by China, Pakistan, Bangladesh, Thailand, Vietnam, Laos, Cambodia, Hong Kong, Macao, Taiwan, North Korea, South Korea and other countries and regions.

From the perspective of technical resource sharing, the research and development process of OUCC's Beidou satellite global positioning and navigation system is inseparable from the mobile phone mobile communication network and Internet information transmission system launched by OUCC.

Beidou satellites use three-frequency signals, while GPS uses dual-frequency signals, which is a significant advantage of Beidou over GPS. Although the US imperialists are now actively developing tri-band satellites, it will take at least 10 years for them to build them and replace them with tri-band satellites when all the dual-band satellites with GPS are aged. And this decade is undoubtedly the dominant period of Beidou.

The three-frequency signal can better eliminate the influence of high-order ionospheric delay, improve the positioning accuracy, enhance the preprocessing ability, and greatly improve the fixed efficiency of ambiguity. And if there is a problem with one frequency signal. The other two frequencies can be used for positioning using traditional methods, which improves the reliability and anti-interference ability of positioning.

At present, the Beidou positioning system launched by OUCC in Asia is the world's first satellite navigation system to provide tri-band signal services.

Basically, no country is willing to take the risk of using services that do not belong to the country's own intellectual technology. Especially for a large country like the United States and the Soviet Union, perhaps restrictions on use will be appropriately relaxed in the civilian field, but in the military aspect. Absolutely do not dare to take such a risk.

Yang Weiping can naturally understand the meaning of the Soviet side, Andropov did not mention the Beidou navigation and positioning system of the Eastern Union when talking about the introduction of Internet information technology from the Eastern Union, and Yang Weiping faintly felt the Soviet Union's sense of defense against the Eastern Union.

With regard to Andropov's invitation to Yang Weiping to visit the Soviet Ministry of Defense and the Soviet Union Combined Armed Forces Operational Command Center, Yang Weiping naturally understood that this was Comrade Lao An's intention to show him the Soviet Union's military strength, and to tell Yang Weiping that the Soviet Union may not be satisfactory in terms of economy, but it definitely stands in the top position in the world militarily.

This kind of gesture can enhance the strategic and political mutual trust between the two countries, close the relations between the two armies, and promote cooperation between the two countries' armies. Of course, Yang Weiping gladly accepted.

This is because in the East Soviet strategic cooperative partnership, cooperation between the two countries in the military field has a special and important position, and it is an important content and support point for the strategic cooperation between the two countries.

On 14 November, Yang Weiping, head of state of the Eastern Union and chairman of the National Defense Military Commission, accompanied by Oleg Dmitrievich Baklanov, vice chairman of the USSR National Defense Committee, visited the USSR Ministry of Defense.

This was the first time that a foreign head of state visited the Soviet Ministry of Defense, and the Soviet military attached great importance to it.

In the morning, the former military Shi fluttered in front of the building of the Ministry of Defense of the USSR. The salute stood majestic.

At nine o'clock, Yang Weiping arrived at the scene.

Soviet Defense Minister Dmitry Mofievich Yazov warmly greeted him in front of the Ministry of Defense building. A grand welcome ceremony was held for Yang Weiping. Amid the majestic military music, Yang Weiping, accompanied by Yazov, inspected the honor guard of the three Soviet services.

The honor guards of the three armed forces of the Soviet Union lined up neatly, and saluted Yang Wei with a solemn and solemn expression. The military band also played the national anthems of the two countries.

After the welcoming ceremony, Yang Weiping met with Yazov, First Deputy Minister of Defense of the Soviet Union Valentin Ivanovich Valentnikov, and senior Soviet military generals.

Yang Weiping said that he was very happy and honored to be the first foreign head of state to visit the Soviet Ministry of Defense, which was built by Chairman Andropov. I believe that carrying out this activity will contribute to the mutual trust between the strategies and policies of the two countries. Closer relations between the two armed forces and promotion of exchanges and cooperation between the two armed forces.

Yang Weiping pointed out that in the comprehensive strategic partnership of coordination between the East and the Soviet Union, cooperation between the two countries in the military field has a special and important position, and is an important content and support for the strategic cooperation between the two countries. Recently. Exchanges and cooperation between the Wehrmacht and the armed forces of the Soviet Union have been continuously strengthened, and high-level exchange visits, personnel training, and military technical cooperation have been carried out very well.

Yang Weiping stressed that in today's world, peace, development and cooperation are the trend of the times, but the international pattern has been deeply adjusted, and the world is still unequal, unbalanced and unstable. Traditional and non-traditional threats are intertwined, and instability continues to spread in some regions.

In the face of the complex and ever-changing international situation, East and Soviet Union should strengthen coordination and cooperation and work with the international community to deal with various threats and challenges. It is hoped that the Wehrmacht and the armed forces of the Soviet Union will conscientiously implement the consensus reached by the two heads of state, make better plans for exchanges and cooperation between the two countries, promote deeper and broader development of relations between the two armies, and contribute to safeguarding the common interests of the two countries and promoting world and regional peace.

Yazov extended a warm welcome to Führer Yang Weiping's visit to the Soviet Ministry of Defense. He said that Yang Weiping was the first foreign head of state to visit the Soviet Ministry of Defense and the operational command center of the Soviet Armed Forces, which fully demonstrated the high level and special nature of the Soviet-Eastern strategic cooperative partnership.

At present, the international situation does not allow for optimism, capitalism, imperialism, extremism, and terrorist forces are rampant and rising, and the world and the region are facing a series of challenges. As a comprehensive strategic cooperative partner alliance, the Soviet Union and Eastern Europe should strengthen military exchanges and coordination to safeguard the common security and international strategic balance between the two countries.

After the meeting, Yang Weiping's Yazov, accompanied by Yazov, visited the combat command center of the Soviet Armed Forces. All the officers of the Soviet Army, Navy, and Army who were on duty at the command center stood up and saluted Yang Weiping. Chief of the General Staff of the Soviet Armed Forces Akhromeyev specially briefed Yang Weiping on the situation in the operational command center.

Dozens of Soviet officers were engrossed in operating and monitoring in front of computer screens. On the huge LCD color display screen, the real-time pictures of the Soviet Army, Navy, Air Defense Force, Air Force, Strategic Missile Forces, and special forces on duty and training exercises are alternately presented. The generals of the Soviet naval fleets who carried out strategic cruising missions in the oceans, the commanders of the Soviet troops in the relevant areas who were on duty, and the responsible persons of various design bureaus and military industrial enterprises that had cooperative relations with the Oriental Union reported on their respective work conditions.

After listening to the report, Yang Weiping said that the visit had enabled the defense forces of the East and the Soviet Union to learn about the achievements of the Soviet Union in national defense and army building, and that tomorrow the defense ministers of the two countries will hold defense consultations, hoping that the armed forces of the two countries will further strengthen exchanges and cooperation and inject new activities and impetus into the development of the comprehensive strategic partnership of coordination between East and the Soviet Union.

After leaving from the operational command center of the USSR Ministry of Defense and the Armed Forces. Yang Weiping made a special trip to the Sukhoi Design Bureau and had cordial exchanges with two old friends, Ivanov and Simonov.

In the VIP reception room of the Moscow headquarters of the Sukhoi Design Bureau, Yang Weiping, Simonov, and Ivanov were conducting in-depth discussions on the further improvement and upgrading of the Su-27.

"Yang, your J-15, I think, should be developed by you on the basis of the Su-27. Simon Love did not call Yang Weiping's head of state, but communicated with Yang Weiping on an equal footing with the mentality of an old friend:

"The Su-27 was designed by you personally, and I believe you have a comprehensive and systematic understanding of the subsequent upgrades and improvements of this fighter. As an old friend for many years, Young. I want to know, if I want to design a fourth-generation advanced combat based on the aerodynamic layout of the Su-27, is it possible?"

Yang Weiping replied without hesitation: "The Su-27 is definitely the most rational and scientific fighter in the world in terms of aerodynamic layout, and there is no one! I believe that since the Su-27 came out, you must have been pondering how to overhaul the Su-27."

The Su-27 improved multirole fighter that you are now developing. The target should be an improved version that must surpass the F-15 and F-16, and must be multi-purpose, all-weather, capable of striking low-altitude objects such as cruise missiles. Equipped with a new RL Su-27 radar system. The airborne active and passive electronic countermeasures system, the new cockpit interface, navigation system, etc., can launch active radar-guided air-to-air missiles and ground-to-ground precision-guided weapons. Right?"

After Simonov and Ivanov heard Yang Weiping's words, they couldn't help but show shocked looks. The two of them glanced at each other, and they could feel how strong the shock in each other's hearts was from each other's eyes.

"Hehe, my old friend. You don't need to be so surprised!" Yang Weiping said with a smile on the ground: "Don't worry, I definitely didn't press the plug-in eyeliner in your Sukhoi Design Bureau." The Su-27 was designed by me, and it is much better than your original T10, I don't say that you all know it in your hearts.

When I first designed the Su-27, I aimed at the imaginary enemy of the U.S. Air Force F15 and F16 and the U.S. Navy F14. Su-27 as an advanced fighter platform. I know better than you how much it is worth upgrading.

Although I don't know how many demonstrators you have developed on the basis of the Su-27, I believe that you must have built a test aircraft for the new avionics and cockpit interface. Maybe you've also installed a phased array radar and an AL-3X series vector thrust engine on this test machine.

Two old friends, I think you should know that in the field of military aviation turbofan engine development today, I, Yang Weiping, dare to say that I am second, and absolutely do not dare to be first! In the research and development of vector thrust engines, I dare to guarantee that the vector thrust engine designed and developed by Rurika is still immature. Its service life is the biggest bruise. ”

Hearing Yang Weiping's words, Simonov and Ivanov once again showed a shocked look that could not be concealed.

"Yang, it is said that the fourth-generation mature high-thrust military turbofan engine WS15 developed by your Oriental Union is about to enter the stage of industrial mass production, in this regard, can you please give a technical guidance to the Rurika Design Bureau?" Simonov said with a very sincere look at Yang Weiping.

"I am still optimistic about the R&D capabilities and technical reserves of the Rurika Design Bureau. Yang Weiping smiled noncommittally: "If time permits, I plan to take the time to go to their side." ”

"Yang, on behalf of the Rurika Design Bureau and all my colleagues in Sukhoi Design, I would like to express my heartfelt thanks to you!" Simonov said as he stood up and bowed deeply to Yang Weiping.

"It's all old friends, so you don't need to be so polite. Yang Weiping waved his hand happily and smiled: "Let's put it this way, the J-15 does belong to the same bloodline as the Su-27." At present, I am planning to make further improvements to the J-15. ”

Seeing Simonov and Ivanov's pointed ears and engrossed attention, Yang Weiping smiled indifferently, and then said: "This fighter, which I tentatively named J-18, in addition to continuing to use the excellent aerodynamic performance brought by the three-wing design, the real focus is on avionics, improving automation, computerization, humanization, and the ability to understand the finger and tube.

As you know, OUCC's avionics design standards represent the most advanced development direction in the world today. But the result of the new avionics is an increase in the weight of the fuselage, which requires other improvements to avoid a decrease in maneuverability, acceleration, and range.

Based on this philosophy, my idea was that in addition to improving the handling performance of the front wings, it was also necessary to equip military turbofans with higher thrust. In addition, the fuel tanks in the main wing and vertical tail have also been expanded accordingly, and the total volume of the fuel tanks is expected to reach 13,000 litres. This will ensure a range of nearly 4,000 kilometers without foreign aid.

The overall appearance of this J-18 is very simple, and most of the antennas and sensors have been changed to hidden. The main airspeed tube was moved from the nose to the original secondary airspeed tube, that is, the cockpit two. The secondary airspeed tube was moved to the rear of the radome. The nose was correspondingly enlarged and thickened to accommodate larger radar and more avionics.

I plan to move the photodetector to the right side of the wind shield, and install a retractable air refueling tube on the left side, and the photodome is moved sideways to make more space to install the refueling tube, and on the other hand, it can also allow the pilot to have a better view. ”

Seeing Simonov and Ivanov take out their notebooks and make deep thoughts while recording, Yang Weiping didn't interrupt them, took out a cigarette and lit one, took two puffs and said: "In addition, I also plan to install retractable night refueling lights on both sides of the cockpit, and the vertical tail is enlarged to get better yaw stability."

At the top of the vertical tail, the undercut of the J-15 will be changed to a straight one, the tail vertebrae will be thickened, and the drag umbrella will be moved from the end of the tail vertebrae to the top, so that the end can accommodate the rearview radar and more avionics equipment. In short, it is required to achieve a three-wing layout, no angle of attack restriction and full digital flight control. (To be continued......)
