Unconsciously, at the end of 2020, with the completion of drilling platforms in the East China Sea and the South China Sea, and the continuous flow of crude oil like black gold began to supply the country, the domestic crude oil supply that was about to be exhausted immediately returned to normal, and the shadow of the oil shortage shrouded in the country was finally dispelled. The biggest unstable factor affecting the domestic economic development has been successfully eliminated, making up for the crude oil supply gap caused by the Persian Gulf War, and more importantly, driven by this strategic investment, as well as the extraordinary prosperity of the military industry, the domestic economy has grown at a high speed against the trend in the face of many unfavorable international situations.

Of course, in addition to the great improvement in the energy supply environment, the full internationalization of the renminbi is even more remarkable, after the completion of the renminbi settlement negotiations with most of the trading partners in Asia, Africa and South America, after bargaining, the EU and CIS countries have also reached similar agreements with the Chinese side, but with an additional three-year transition period.

In this way, except for a few countries such as the United States, Japan, South Korea, the United Kingdom and Canada, China has completed the arduous task of promoting the internationalization of the renminbi in most countries in the world. Compared with oil development in the East and South China Seas, the internationalization of the renminbi has a more far-reaching impact on the domestic economy.

It can be said that in 2020, in the midst of ups and downs, the domestic economic situation will still maintain a good situation.

Compared with the well-known economic achievements, although the achievements in the military industry are very low-key due to secrecy reasons, ordinary people do not know much, but in the eyes of the military leadership, the number of achievements achieved by the Shenlong Program and the Qianlong Program led by Duke is simply unbelievable.

The coast of the South China Sea.

A bunch of high-ranking generals of the General Staff, the General Assembly and the Navy Command gathered together, they were waiting for the results of the exercise of a modernized 039 experimental submarine, and now the Qianlong program is progressing very smoothly, and the Golden Dragon battery for the submarine has completed the development stage and began to enter mass production, this model is the GD-100 Golden Dragon battery, although the mass power is slightly reduced compared to the early GD-10, the weight of 100 kg is only 110KWh, a decrease of about ten percent, However, it not only improves the problem of rapid decline in low-temperature working performance, but also greatly reduces the production cost to about 70% of the original, so that in the case of spending more than 80 million battery budgets, the endurance of the submarine after the transformation has increased by more than 3 times compared with the original.

Battery transformation is the largest cost expense in the modernization of this submarine, under the renovation budget of 150 million yuan per submarine, the remaining money in addition to the installation of the "fish" communication system and the addition of 6 torpedo storage space, the Qianlong modernization research team also focuses on the comprehensive renewal of the submarine's electronic system, the original budget is only to update the main engine suitable for the theater joint combat tactical system, but now the host system used for this system is provided by SAL super small machine, A minicomputer built with the new G3 chip would cost only a few million dollars, so the remaining budget could be used to update the computing host of the sonar subsystem.

The computing core has also been updated, that is, in addition to the transformation of the battery power system and the external communication system of the "fish", the electronic system of the entire submarine has been updated.

At present, the military's theater-based joint combat tactical system is very mature, and the integrated naval and air combat system developed with the China Aegis is running very fast on the new G3 series super small machine developed by SAL.

More importantly, from the Chinese Aegis system research and development of the use of the new sonar intelligent analysis engine, so that the operation of the sonar system completely out of the manual judgment stage, the new sonar intelligent analysis engine not only analysis accuracy is higher than manual judgment, and the reaction time is not in an order of magnitude, with this thing, you can realize the integration of submarine observation, targeting and attack, which makes the 039 modified experimental boat automation combat capability has been greatly improved.

Although from the preliminary theoretical analysis, the combat effectiveness of the submarine after the modernization has been greatly enhanced, and everyone has high hopes for this, but no one knows what the result will be, and no one has a bottom without conducting actual combat exercises.

The combat area of the confrontation exercise between the old and new submarines is carried out in a sea area of about 60,000 square kilometers, and the time is 24 hours, and the new submarine after the transformation acts as the attacking blue army, and the combat goal is to survive in this exercise sea area for 24 hours or sink all the Red Army submarines, while the four 039 submarines that serve as the Red Army's mission need to find and destroy the blue army within 24 hours, and at the same time, two anti-submarine helicopters will carry out anti-submarine reconnaissance missions over the exercise sea area, and at the same time, the reconnaissance results will be indiscriminately red in real time. The blue submarine is sent over the area of the exercise, acting as an anti-submarine AWACS aircraft.

For the Red Army, which is carrying out the task of "hunting," this seems a bit unfair, but because of the huge disparity in strength between the two sides of the confrontation, it is reasonable to test the power of the new submarine's air-sea integrated operations in a 4-to-1 situation, so this time it deliberately chose to conduct the exercise in a narrow sea area 150 kilometers wide and 400 kilometers long, so that the anti-submarine helicopters can effectively control the activities of submarines in the shallow waters of the entire sea area.

In addition, the Blue Army submarine is not allowed to use the shutdown method to evade, and the exercise command will no longer set up a plan, leaving the two sides to play freely.

In the exercise, the 039 improved experimental boat that served as the Blue Army first set off in advance to enter the exercise area, and after reporting to be in place before the deep dive, the "Fish" communication system was released, and then the Red Army's four 039 submarines began to sort.

The two Aegis-II destroyers of the South China Sea Fleet, which were responsible for the antisubmarine reconnaissance mission in the exercise area, were already ready in the exercise area, and after the Blue Force submarine dived deeply, they quickly released their antisubmarine helicopters to begin antisubmarine reconnaissance operations in the exercise area. They quickly detected four 039 submarines driving at high speed into the exercise area, and for this semi-submersible 039 submarine, the sonar system of the anti-submarine helicopter can be monitored from a distance of 30 kilometers.

However, as the Red Army submarines that entered the exercise area also began to dive deeper, the anti-submarine helicopters gradually lost their traces.

For the 039-class submarine, there are only two situations in which the anti-submarine helicopter can not find its trace, one is to stop and sit on the bottom, so that the submarine will hardly make any sound, and the anti-submarine sonar system will naturally completely fail; The other is to dive to a depth of 300 meters and move slowly at a very low speed, which means that when it is battery-powered at a speed of 2-3 knots, the noise is so small that it is exactly the same as the background noise of the ocean.

After the four submarines of the Red Army entered the deep dive, the four submarines were about 10 kilometers apart, kept in touch with the hydroacoustic communication system, began to evade the anti-submarine helicopters in the air, and dived at a speed of 7-8 knots.

This tactic is familiar to these experienced 039 submarine captains, there are only 2 anti-submarine helicopters in the exercise area, and they have to return to the mothership every 1 hour or so for refueling, so the Red Army submarine captains are not too worried that they will be targeted by these anti-submarine helicopters all the time.

According to the requirements of the exercise, the Blue Army strictly prohibits the use of the shutdown and sitting on the bottom to circumvent, so the 039 modified experimental boat will be at least 2-3 knots of speed to swim, that is to say, the Blue Army can not always stay in a fixed sea area, for the Red Army submarines, to search in a dragnet formation, is a very good tactic, not only in a large range of carpet search, but also in the encounter to play the advantage of group fighting.

It's just that although their idea is very good, but the realization is not so ideal, because their battery power is limited, even if it dives at a speed of 7-8 knots, it can support more than 100 nautical miles at most, so when 10 hours have passed, the Red Army submarine has to sail in a semi-submersible state, exposing its track to the eyes and ears of the anti-submarine helicopter.

After receiving the information of the Red Army submarine, the "fish school" system of the blue army submarine took the initiative to attack, using the location information of the Red Army submarine provided by the anti-submarine helicopter, quietly approaching to a range of about 40 kilometers, and then using the anti-submarine helicopter sonar information to guide the launch of the fish-six improved torpedoes with the warhead, each time 2-3 were launched, and the attack was immediately accelerated to disengage, it was this simple tactic, but the Blue Army frequently succeeded, and destroyed all four submarines of the Red Army within 24 hours!

Looking at this unexpected result, all the leaders of the navy, the General Staff Department, and the General Assembly were a little stunned.

This is even more desirable than the theoretical speculation! When the news came that the last Red Army submarine had been "hit" by the Blues, all the generals couldn't help but stand up and applaud Duke, who participated in the exercise!

Thanks to the large battery power, the Blue Army submarine has been in a deep state of diving from beginning to end, and even after hitting the last Red Army submarine, the remaining battery power is nearly one-third, which means that the Blue Army submarine still has the ability to continue to dive at low speeds for at least 400 nautical miles.

This astonishing test result made several generals of the Navy Command strongly request Duke to join the development of the Type 097A attack nuclear submarine and the 096C strategic nuclear submarine, and provide technical support for these two major naval projects, especially the simulation in the design process, the electronic system on board, and the perfect coordination of the Blue Army submarine with the anti-submarine helicopter through the "fish" communication system, so that these generals can see another new way of submarine warfare, whether it is for anti-submarine warfare in the waters around our country. In terms of the future of aircraft carrier formation operations in the world, this new anti-submarine tactic is very important.

As for the original renovation work of the Qianlong Plan, the Navy Command demanded that all efforts be made to complete the renovation within one year, and the combat effectiveness of this submarine modernization project has been increased too obviously, and the Navy urgently needs to improve the combat capability of its submarine force, which is a relatively weak link in the current various branches of the armed forces.

When more than 30 039G and 636G submarines enter service, it is enough to solve the urgent needs of the Navy, and after the nuclear-powered 041 submarines follow the two Beijing-class aircraft carriers, the Navy will no longer worry about the overstretched anti-submarine warfare capability in territorial waters.
