Traveling through the sword to engage in military industry.

During the fifth five-year plan, the Communications Technology Research Center of the Liming Institute of Southeast University once again made a major technological breakthrough!
Optical fiber with 1Gb transmission capacity was invented and soon put into mass production, combined with Gb fiber optic interface switches and routers. Dongda originally had a 1-megabit cable backbone network, which posed a serious bottleneck in national network switching. Although the bandwidth could be increased by increasing the number of cables, the cost of building a Gb transmission system was staggering in terms of the transmission distance and speed of the cable. Therefore, under Ren Zhong's intervention, the construction of the first national network was limited in scale, pending the development of the next generation of transmission technology.

Now that fiber optic transmission technology has emerged, the construction of the national backbone network has suddenly begun to accelerate.

Today's technology has reduced the construction cost of long-distance backbone networks by an order of magnitude!

After a year of vigorous network construction, the backbone network of Southeast University has jumped from the Gb level to over 100 Gb. The originally restricted network applications have suddenly begun to explode, from the original simple text transmission to applications such as Qiuqiu. The first generation of products only had the function of text chat communication.

Because at this time, the network terminal access bandwidth for each user is basically limited to a low-speed connection level of 64KB.

However, after the network is upgraded, the bandwidth of each user can be increased to about 1Mb, which is equivalent to a major speed-up of the national network. Such bandwidth can already transmit compressed images and voice.

As a result, the world's first generation of the Internet began to evolve from text-based forums and websites to the second generation of interactive new websites with pictures and texts as the main component. Internet applications such as Weibo, BBS, and BLOG began to be introduced at the same time. Ren Zhong did not rely on his foresight to monopolize these applications.

In his mind, the development of these digital applications must flourish to create the colorful background of this world. Of course, these companies are limited to the University of Tokyo. For those outside the University of Tokyo, it is better to let the pawns ambushed by the Qianlong Plan to monopolize them.

When the Fifth Five-Year Plan was completed, the first version of the World Free Trade Agreement was signed. The first batch of about 70 leading countries signed the agreement, including the University of Tokyo, and the top 50 countries in the world's economies all participated.

At the end of 1970, when celebrating New Year's Day 1971, the University of Tokyo announced that the national GDP would continue to maintain a double-digit growth rate of 13% after careful calculation and forecast. It jumped from 8900 billion US dollars in the previous year to the first place in the world and successfully exceeded one trillion US dollars!

When the news came out, one billion Dongda people cheered!
The Rogue Eagle, which used to be ranked first in GDP, increased slightly by about 9000% from the total amount of 1970 billion US dollars in the previous year. The total amount in 9315 was billion US dollars. Although it has maintained a long-term growth, its growth rate is no match for the University of Tokyo.

The fact that the university would be surpassed by the University of Tokyo had actually been predicted in major economics journals a long time ago.

However, when this prediction actually became a reality, the entire North American upper class felt a little sour.

After all, it has been less than eighty years since China's total industrial output value became the world's number one in 1894, and now it has lost its position as the world's number one.

Although North America still far exceeds the University of Tokyo in terms of per capita GDP, the current Rogue Eagles are just over 3 million, with a per capita GDP of more than 3 US dollars, while the University of Tokyo has a per capita GDP of only US dollars, which is exactly three times the latter.

However, this cannot stop North America from reflecting.

After careful analysis, they almost unanimously agreed that the most important reason was the backwardness in technological development!
In the most important IT industry today, North America is basically three generations behind the University of Tokyo!
After so many years of development, by 1970, the computer chip of the University of Tokyo had developed to 686, while they had just broken through the large-scale mass production of 386. Because the most important chip manufacturing equipment is the lithography machine, the most advanced lithography machine of the University of Tokyo is kept secret, and there is no intention of launching it for sale on the market.

Even now, few people in the world know what level of development the most advanced lithography machine of the University of Tokyo has reached.

Just know that it is definitely far ahead of the world.

With the joint research and development of MBI and Bell, two leading North American semiconductor companies, North America's lithography machines have barely broken through to the 1-micron level. After reaching this level of lithography processing, Bell and MBI's top chip process research experts feel that the road ahead is coming to an end, and now they need to take a new path.

According to the results of theoretical research, when the light source for lithography reaches 1 micron, it will need to be replaced, otherwise the new lithography wavelength will not be able to support further development.

But what exactly the new lithography machine is like? Experts such as MBI and Bell, who had no ideas to learn from, had to spend money to explore multiple technical paths.

The Tokyo University, which has been strictly guarding against lithography machines and has hardly revealed any technical ideas, has never thought of making money by selling advanced lithography machines. They only consider selling lithography machines that their competitors have already mastered and occupy the market at a price that is about a quarter lower than that of their competitors.

As a result, competitors have little chance of making money from selling their own lithography machines, except for gaining benefits from the chip production process to support the development of the next generation of lithography machines.

It can be said that in the world of Bright Sword, the Rogue Eagles suffered a lot from the technological lead of the University of Tokyo.

As for the European continent, they have already laid flat in the semiconductor field.

In the areas of machinery, communications, aviation, railways, etc., Europe continues to catch up with the University of Tokyo. There are a number of potential companies under the Qianlong Plan and several leading companies that have the opportunity to jointly develop with the University of Tokyo. On the surface, Europe's technological development is still vibrant and no worse than that of North America.

Especially in the field of aviation engines, after cooperating with Dongda to produce the RB211 three-rotor engine, it has entered the world's top new large-bypass turbofan aviation engine industry in one fell swoop, which not only solves the power needs of new passenger aircraft.

In John Bull's research on the new Tornado fighter, the improved new generation three-rotor engine RB199 was transformed from the technology and inspiration gained from the RB211 research.

Compared to the original development, which took them ten years and 67 test engines after massive tests, the Rolls-Royce in the world of Bright Sword had it much easier than this. Ren Zhong copied the RB211's homework and avoided all the big pitfalls. Similarly, Rolls-Royce's RB199 also avoided many detours, and the RB211 medium-thrust engine was developed within two years after the success of RB199.

RB199-104性能指标：长3.6米；直径0.72米；干重976公斤；推力40千牛（加力推力73千牛）。虽然说比东大WS9最大推力要差不少，但是推重比却要高出一大截，推重比超过了7的水平。这样，亮剑世界狂风战斗机的研究就大大提前了。

Relatively speaking, apart from avionics, this is a fighter with performance very close to that of the J-9, but it was released ten years later than the J-9. The current J-9 has undergone a second improvement and has become the J-9C. The biggest change is that the WS-9 engine has been modified to become the WS-9C. Its greater thrust and better fuel economy bring greater maneuverability and longer range.

However, J-9C is no longer the best fighter of Dongda. Now the best fighter of Dongda is J-12, which is basically developed according to F15 to be the next generation of heavy fighter, and it has directly robbed the North American giant McDonnell Douglas!
From F-4 to F-15, the path that McDonnell Douglas has taken is of course also smooth for Dongda.

However, in the single-engine light fighter J-13, due to the limitation of the aircraft engine, it is impossible to copy the F-16. Ren Zhong chose the JAS-9 Gripen fighter, which is relatively similar to the J-10, for the WS-39C aircraft engine. It is 14.1 meters long, 8.4 meters wide, 4.5 meters high, 6.8 tons empty, and can reach a maximum take-off weight of 14 tons. The key is that its power is a medium-thrust RM12 engine that can provide the Gripen with 54 kilonewtons of thrust. If the afterburner is turned on, the afterburner thrust can be increased to 80 kilonewtons.

These indicators are no problem for WS-9C. Now WS-9C has a thrust of 75 kN and afterburner thrust of 115 kN! The power is not much different from the early version of J-10. Unfortunately, the information available for J-10 is not as much as that for Gripen fighter. In this regard, Ren Zhong simply developed it based on the mid-term improved model of Gripen fighter. This fighter has a similar technical route to J-10, both of which are canard layout.

Most importantly, the J-12 and J-13 fighters are designed according to the specifications of the fourth-generation fighters! The fly-by-wire control and static instability design concepts are introduced, which completely subverts the past aerodynamic design methods and flight control mechanisms. A large number of sensors and new aircraft engines with a thrust-to-weight ratio greater than 7 are used, and the avionics are fully digitalized.

In J-12 and J-13, a large number of ARM11 chips and 586 chips are used as the computing power source, and Ethernet network transmission is fully realized in terms of transmission, which greatly enhances the sensing capability of the fighter.

Coupled with the PD second-generation radar system PD-120 and the standard data link LINK-100, the new generation of fighter jets have a far greater ability to coordinate operations than the previous generation. Today’s combat coordination does not only rely on direct communication to allow pilots to cooperate tacitly.

Instead, the sensor and radar data of the two fighters can be shared through the data link LINK-100 system. The computing power of the two fighters and the maximum efficiency of the current weapons can be locked through an automated combat system to lock the five most dangerous targets at the moment, and then guide the fighter pilots to make selective attacks!

You should know that in the case of a single aircraft, each onboard radar can track ten threatening targets at the same time, and then select 2 to 3 of them to attack.

After the two aircraft merged into a combat partnership, the field of view of the fighter jets was suddenly expanded to the shared field of view of the two aircraft, and two radar systems were used to perform dual positioning of enemy targets - the accuracy of this positioning is more accurate than that of a single positioning, and for guiding missile attacks to hit targets, the success rate of an attack can be increased by at least 10%.

Because when the target is locked by two radars, the combat partner guidance will guide the two fighters to automatically bite the target aircraft for tracking and attack!

After the computing power has expanded in the past five years, the new ARM1176JZ-S chip has the characteristics of low power consumption and high performance. It has been widely used in embedded avionics equipment and is the core of airborne data calculation. As for the two 586 hosts, they form the main and standby system, controlling the cabin data display and map display functions, and guiding fighter pilots to launch attacks.

When these two fighters achieved initial mass production on a small scale, they fought against the early second-generation fighter J5A and achieved clean scores of 10 to 0 and 20 to 0!
Even when facing the J-9 fighters, the new J-12 and J-13 maintained an overwhelming advantage. Single-machine combat can ensure 1VS3 or more, and dual-machine combat can easily reach 2VS10. The data sharing and combat sharing functions are much more powerful than the simple manual combat mode.

Because human vision and reaction ability are far less than that of airborne radar and their response time is far less real-time.

More importantly, the built-in combat escape system will automatically prompt its own safety range based on the opponent, and will know how many kilometers of distance it needs to maintain for relative safety when facing different types of opponents, while also being able to launch a fatal attack on the opponent.

From a technical point of view, this principle is not difficult. As long as the model of the opponent's fighter jet can be determined through radar signals, the type of the opponent's air combat weapons, the maximum effective range of these weapons and the escape area range of the J-12/J-13 when facing these weapons can be deduced.

In this way, pilots flying the J-12/J-13 can ensure their own safety based on this prompt range.

Generally speaking, this kind of black technology should not appear in this era. However, for Ren Zhong, this is not just a small-scale application of the main world's artificial intelligence.

As long as the radar can measure the opponent's target accurately enough, there is no major threshold from the perspective of computer logic.

With these two new powerful weapons, Ren Zhong feels that the sky will never fall again.

The J-12 can be an air superiority and multi-functional heavy fighter to protect the country, while the J-13 can be used in more combat areas and will be transformed into a carrier-based aircraft to take on the burden of the next generation of carrier-based air superiority fighters. As for ground attacks, they will continue to be handed over to the new generation of Q-9C attack aircraft after the engine replacement. As a Q-9C with enhanced power and strengthened new protective armor, its battlefield survivability has been greatly improved. All core parts have the ability to resist heavy machine gun scattering, which makes it safer for performing frontier bombing missions.

If there is any disadvantage, it is that the cost of these two fighter jets is much more expensive than the previous generation.

Even the J-13 light fighter is more expensive than the old-generation J-9 fighter. As for the J-12 heavy fighter, its cost is directly doubled that of the J-9.

The application of new sensor systems, new materials and new radars are all places where big expenses are spent, causing the cost of the new generation of fighter jets to soar significantly.

In view of this, the time is not yet ripe for these two powerful weapons to replace the previous generation of fighter jets on a large scale. Instead, they will be replaced one aviation regiment at a time according to the plan.

The current production line that produces hundreds of passenger planes a year through the manufacture of civil aircraft will quickly be converted into a fighter production line to increase production capacity in real wartime. Therefore, after the research is completed, it is more equipped in the form of a demonstration aviation regiment, so that the Air Force can become familiar with these two fighters and train a considerable number of pilots.

Make preparations in advance for the large-scale deployment of new powerful weapons in the future.
