readx; Although there has been no large-scale military conflict since 1923, the military confrontation between the two sides has not relaxed in the years since, and occasionally some small-scale armed conflicts have broken out, but both sides have restrained themselves and some small-scale battles have been suppressed.

Such a long-term military confrontation has led to a military confrontation between the two sides, which is not only reflected in the actual deployment of troops on the front line, but also in the competition of various new military equipment between the two sides.

After all, the hostility between the two is so strong, it belongs to the state that a large-scale war may break out at any time, and in this case, neither China nor the Soviet Union nor Russia dares to relax their vigilance against each other, and each side has sent a large number of military spies to spy on the military intelligence of both sides.

For example, when China's T9 medium tank was put into large-scale service, the Soviet Russian side soon learned some of the general surnames of the T9 tank through espionage and other means, and for about 130 years, China's T9 tank surname can belong to the absolute advanced ranks, and the emergence of the T9 tank made the Soviet Russia even more worried, so the Soviet Union and Russia accelerated the research and development of several tanks, and in order to counter the 75 mm tank gun of the Chinese T9 tank, the newly developed Soviet Russian tank is also extremely concerned about the protection capability.

After all, Soviet Russia and the Russian Republic are both Slavs, and it is easier for spies to mix in with each other, so China and Russia learned about the new tank research and development plan of Soviet Russia so quickly.

Therefore, in order to counter the new tanks being developed by Soviet Russia, the Chinese side also carried out the research and development of new tanks early, and the Z45 heavy tank research and development plan and the T9U tank research and development plan are the products of this background, and after the development of these two tanks, they were officially named T11 tanks and T12 tanks by Chen Jingyun.

These two tanks, which are still in the state of research and development tests, are used by the Chinese Army to fight against the new tanks being developed by Soviet Russia, which can be regarded as a kind of preventive research and development program.

And also in the prevention surname research and development program also assault artillery. The concept of assault artillery came from the Second Panzer Army stationed in Siberia, because the Second Panzer Army has been stationed in Siberia for a long time, and its main combat goal is to confront Soviet Russia, which is different from the First Panzer Army stationed in the Northeast and the Third Panzer Army stationed in the North China Plain.

For example, the intended combat area of the First Panzer Army is the four northeastern provinces, the eastern part of the Russian Republic, and the Korean region, and the main enemy is the original one, and because the first armored army lacks armored forces, the tanks equipped by the First Panzer Army are mainly T6 and some T9 tanks, and there are relatively few real heavy tanks.

As for the Second Armored Army, the target is Soviet Russia, and the armored strength of Soviet Russia is not weak, although their tank surname is not good, but the development potential is much greater than that of "Ben", in recent years, various tank research and development plans have been put forward one after another, so that the pressure on the Second Armored Army is also increasing.

The terrain in Siberia is also relatively good, so the tanks equipped by the Second Armored Army are relatively heavy, for example, most of the previous T7 series heavy tanks are deployed in the Second Armored Army, and the Chinese Army's current new tank T9 medium tank is also preferentially deployed in the Second Armored Army, in addition, the Second Armored Army is also the first unit in the army to be equipped with large-caliber self-propelled guns, and it has modified multiple 155 mm caliber self-propelled howitzers.

The Second Panzer Army is facing increasing pressure from the Soviet and Russian armored forces, and there is a great demand for anti-tank firepower, in addition to wanting to equip more advanced new tanks, it also has to think of other ways to increase anti-tank firepower, on the one hand, there is a price limit, not to mention that the price of T11 heavy tanks is not cheap, even the price of T12 tanks is not cheap, and on the other hand, it is for those tortoiseshell tanks in Soviet Russia and those tortoiseshell tanks in European countries, Tank guns on China's existing ordinary tanks simply cannot penetrate. Not to mention that there are still a large number of T6 tanks in service on the 57 mm tank guns that are powerless, even the 75 mm tank guns of the T9 tank are easy to say, but the T9 medium tank, as China's latest cutting-edge tank, actually has a total output of only more than 300 units, and most of them are T9A and T9B models that were urgently produced during the war in 1930 and 1931, and the number of T9C and T9D models produced in recent years is not much, that is, more than a dozen of each model, There are only twenty or thirty cars.

The total number of active tanks in China has exceeded 2,000, and the largest number of these 2,000 tanks is the T6 tank, almost more than 800, in fact, the production of T6 tanks is far more than 800, because the T6 has been in service for many years, and the battle damage is dozens of them, and then there are various reasons for scrapping together is not less, the total number of T6 tanks in service in the Chinese Army before and after is close to 1,000, and the T6 tank is not only in service in China, but also the main tank of the Russian Defense Forces, The Russian Defense Forces are also equipped with more than 100 T6 tanks, in addition, T6 tanks are also China's main export tanks, Persia has purchased twenty or thirty tanks, and Argentina in South America has also sold a little, the total output of T6 tanks is almost 1,300 units, not counting various T6 tank chassis modified combat vehicles, such as self-propelled guns and so on.

The next second largest number is the T8 series of light tanks, almost four hundred, the T8 series of light tanks are mainly used as reconnaissance tanks, widely equipped in various armored divisions, mechanized divisions, and in recent years, the establishment of the Reading Armored Regiment also has a subordination, the application is very wide, and other tanks are used intensively, so the most common thing that ordinary citizens see is not the T6 tank with the largest number of equipment in the Chinese Army, but the T8 tank with the most extensive equipment in the troops. After all, most of the T6 and other tanks are centrally equipped, for example, the T7 tank has only three battalions in total, and all of them are in the Siberian region, and ordinary people can't see it at all, while the T8 tank basically has equipment in armored units all over the country, and the people can see it more often.

After the T6 tank and the T8 tank, the T9 medium tank was followed, with more than 300 units. Then there are the T7 heavy tanks, which are basically deployed in the Siberian region, and then there are more than 100 T10 light tanks, mainly deployed in the southern provinces of China.

The above T6 medium tanks, T8 light tanks, T9 medium tanks, T7 heavy tanks, and T10 light tanks. The above five tanks constitute the main armored force of China's active armored forces, and although there are still some messy and old tanks, they are all complex models and not many in number, and there is basically no way to count on them in the event of a war.

Among the above tanks, the most powerful is the T9 medium tank, which has a 75 mm caliber tank gun, while other tank guns are relatively weak, especially the T6 tank, which is still used as the main force, and the 57 mm tank gun on it is obviously inadequate.

In the face of the thicker and thicker armored defense of Soviet and Russian tanks, the Chinese Army had to find another way in addition to developing new tanks, and the assault gun that Chen Jingyun saw now was one of them.

The army saw that since the new tanks have not been put into service so quickly, and the armored forces now need large-caliber tank firepower, so they paid attention to modifying the tank, directly using the existing tank chassis, and then installing large-caliber cannons, in order to equip large-caliber cannons, they do not require any mobile surnames, not even turrets, in fact, in terms of the chassis of more than 20 tons of T9 tanks, the installation of 75 mm tank guns is already the limit, and the army side in order to strengthen firepower, It is necessary to install a 105 mm caliber cannon, which is simply a trolley anti-cannon, and the mobile surname and the protective surname can be don't want.

"The concept of this assault gun was first proposed by the Second Panzer Army, and they themselves tried to equip the chassis of the T6 tank with a 105 mm cannon, and then we went to see it after we knew about it, and it turned out that the prototype they experimented with had great potential for development, so they came back and made this specially."

Luo An said: "This prototype uses the chassis of the T9 tank, and the gun on it is a 105 mm caliber tank gun produced by Tianjin Youbang Machinery Company. ”

The Tianjin Youbang Machinery Company in his mouth was a large heavy machinery company that was developed in China in the mid-20s, and it was a merger of several large machinery enterprises in the north, which originally produced rifles and artillery for several army companies, and was one of the defense contractors of the Chinese side and the largest machinery enterprise in China's northern region. Later, it cooperated with Wuhu Special Machinery Company, that is, the original Wuhu Tank Factory, to develop a 75 mm 35 times the caliber of the tank gun, that is, the main gun on the T9 tank, thus stepping into the production of military artillery, and then continued to cooperate with Wuhu Special Machinery Company to design and develop a series of tank guns, including the 57 mm 40 times the caliber main gun on the T10 light tank, and the 105 mm 40 times the caliber main gun on the T11 heavy tank. Seventy-millimeter forty-caliber guns on the T12 tank.

Today, Tianjin Youbang Machinery Co., Ltd. has become a major R&D and manufacturer of tank artillery in China, and is a strategic partner with Wuhu Special Machinery Co., Ltd., China's largest tank R&D and manufacturing enterprise.

"This tank gun is the same main gun as the T11 tank?" Chen Jingyun asked.

Luo An said: "Yes, it's the same one, both of which are Y105L40 tank guns from Tianjin Youbang Machinery Company." ”

Looking at such a small hull with such a large tank gun, no matter how you look at it, you must know that the T11 heavy tank is more than 40 tons to carry a Y105L40 tank gun, but the assault gun in front of you uses a T9 chassis that is a whole circle smaller, and it is strange to be able to match.

"Have you tried it, what can the surname be?" Chen Jingyun continued to ask, he knew that there was such a thing as a self-propelled anti-tank gun, although the assault gun in front of him did not command it, but they still made it themselves, it can be seen that the world is not inseparable from themselves, without themselves, the world's tanks, aircraft carriers, and aircraft can still develop very well.

Luo An said: "It has been tested many times before, and the performance is quite good, the firepower of this assault gun is enough to be comparable to the T11 heavy tank, but it is much cheaper in terms of cost, and the production process is relatively simple, which is very suitable for supplementing the anti-tank force of the armored forces!" ”

The assault gun in Luo An's mouth was made for anti-tank, and it was those tortoiseshell tanks in Soviet Russia, otherwise why would it take so much effort to equip which 105mm cannon to use.

Chen Jingyun said: "Well, yes, what the Equipment Department wants here is this spirit of innovation, not limited to narrow thinking." ”

The innovation of weapons is very important, the emergence of a practical new weapon, enough to have a significant impact on military strategy, and this kind of thing has been proven when new weapons such as heavy machine guns, tanks, and airplanes appear, although Chen Jingyun knows that the current development of military equipment is about to be in line with modern standards, and the epoch-making weapon concept has appeared except for helicopters, and the weapons and equipment in the thirties are almost the same as those in the 21st century. It's just that the technology content is lower, but the tanks are still those tanks, the aircraft carriers are still those aircraft carriers, and the planes are still those planes.

After the thirties, there was not much room left for future generations to innovate, one assault gun, one helicopter, and one jet, and other bits and pieces could not affect the overall situation.

Thinking of this, Chen Jingyun felt that it was necessary to do it first, for example, this helicopter is also regarded as the army's equipment, and after watching the exhibition of new equipment, Chen Jingyun proposed a plan to the army to develop a helicopter, of course, he did not say that he wanted the equipment department to do it in a short time, but just said that they should carry out some theoretical research now.

In addition to this, Chen Jingyun also plans to study jets in advance. However, for the research of jet aircraft, China's technology is still somewhat weak, anyway, it is impossible to come up with jet aero engines. 、

In the aerospace field, China's technology in the aerodynamic layout of aircraft is considered the best, and the level of air-cooled aero engines is not bad. The technology of liquid-cooled engines is a little poor, and the technology of the Americans in this area is good, and the Germans can also do it, so after China encountered problems in introducing liquid-cooled aero engine technology in the United States, it cooperated with the German side and prepared to develop liquid-cooled aero engines together.

If the above air-cooled engine and liquid-cooled engine are relatively easy to solve, then the jet engine is not high, this thing requires much higher technology than propeller aircraft, with China's industrial technology base in the early thirties can not be done at all, this thing is more difficult than rocket engines.

Although it is also difficult to use rocket engines, this thing is related to missiles and whether or not nuclear bombs can be sent to the United States and Europe in the future, so Chen Jingyun attaches great importance to this at the same level as nuclear bombs, and began theoretical research more than ten years ago.

In the jet plane, although Chen Jingyun also knows that this is the trend of development, he also knows that the development of the aircraft has to come step by step, and it is absolutely impossible to say that he will directly go to the sky to engage in jet aircraft, he has to go from the air-cooled engine and the liquid-cooled engine step by step, and according to the historical time, it will only appear in about 40 years.

Although Chen Jingyun will not develop jet aircraft during the First World War or the twenties, he will not wait until the '40s to develop it, and now it is the mid-thirties, which is just the right time, and he can also work with the German side. In any case, we have already cooperated with Germany in the development of liquid-cooled engines, and it will not be a big problem if we work together to develop jet engines.

These studies are all advanced research, which belongs to the kind of similar that cannot see the results for three or five years, but Chen Jingyun is also used to this kind of thing, and he is very patient with the research of new technology, for example, this radar has been studied for almost ten years, and now it has just been figured out, and for example, nuclear bombs and missiles, he Chen Jingyun has spent more than ten years to support personnel in research, and now he has not even seen the shadow of a nuclear bomb.

However, since last year, that is, in 1933, Chen Jingyun has officially transferred the Institute of Nuclear Physics to the political axe, after all, even if he Chen Jingyun's personal money is more, he has also experienced such a huge expenditure as the research of nuclear bombs, especially now that the theoretical work of the Institute of Nuclear Physics has been done, the next thing is to carry out large-scale tests and purify nuclear materials, these tests and purification require very large funds, and must be supported by the state to be able to continue.

Therefore, every year there is an extra huge amount of transfer funds from the presidential palace, not to mention the purpose of this fund, not to mention that other people do not know, even Chen Cai, the head of the investigation bureau, does not know, he only knows that these funds are used for certain research, and he does not know what to study specifically. As a matter of fact, as far as Chen Jingyun and several people in charge of the nuclear weapons program headed by China want to carry out a nuclear weapons research program, many of the people involved in the program know that they are conducting research in nuclear physics, but they will never know that they are developing a nuclear bomb.

The whole plan is extremely hidden and scattered, the research base is set up in the northwest desert region, in addition to this general base, in fact, there are many laboratories and enterprises indirectly involved in this plan throughout the country, after all, to manufacture nuclear weapons, what is needed is the cooperation of the entire country's industrial sector, and many domestic enterprises are directly or indirectly contributing to this nuclear weapons program, such as Fule Electric has received many parts and components research and development contracts, It is naturally impossible for these parts to be used in the manufacture of centrifuges, and there are also several other top technology companies in China, they are required to provide some high-end technology parts and equipment, and they do not know that the equipment assembled by these parts is a part of the nuclear weapons program.

According to the experts at the nuclear physics laboratory, at the current scale, they will be able to purify enough raw material to carry out the planned nuclear weapons detonation test, according to the experts at the nuclear physics laboratory.

In fact, China's current nuclear weapons program is much smaller than the Manhattan Project in history, the Manhattan Project in the history of the United States is very tight, and the time limit of China's current nuclear weapons program is very relaxed, and the theoretical research has been carried out for more than ten years, and it is also peacetime, so there is no need to ask for nuclear weapons all at once, so the scale of the current test is smaller, after obtaining sufficient test data, At that time, it was the stage of large-scale and large-scale production of nuclear weapons.
