E: I'm a little late, sorry

The main reason why Wen Desi is in such a hurry to put the satellite up is that the central government organs need world intelligence. It is precisely because they come from later generations that they are more and more aware of the benefits of artificial satellites, and they are really not used to doing anything without satellites. Without satellites, no matter how good the information is, it won't come out.

In particular, Europe is in the heat of the war, and China is very concerned about the situation there, but if it does not have reconnaissance satellites, it will not be able to grasp real-time intelligence. Although Mr. Wen still has unmanned exploration vehicles in his hands, and they also have many advanced exploration instruments in later generations. But after all, the main work of these things is used for geological surveys, and it would be too wasteful to use them just as reconnaissance tools. And they are also slower, and if you need to detect the situation in a distant area, it takes a long time for these things to get to the scene, and the daylilies are cold at that time. The most important thing is that these things are not replenished, and if they are broken, they are useless.

Although there is an early warning airship now, which can play a part of the role of reconnaissance, there are many innate limitations in the airship itself, and it cannot be completely relied on. Now the Taibai 1 launched by China only takes 70 minutes to circle the earth, and it only takes 70 minutes to reach the scene at most if you want to reconnoiter any place. Second, its detection range is very wide, and a reconnaissance of several hundred thousand square kilometers at a time is a piece of cake for it. Moreover, with the current technology of other countries, it is almost impossible to detect its detection. These advantages cannot be replaced by any kind of reconnaissance equipment.

Of course, satellites are also its limitations, such as being greatly affected by meteorology and not being able to distinguish too small targets, but these can be solved by improving technology. In addition to reconnaissance, the role of satellites in the fields of communications, navigation, meteorology, and scientific research is even more important.

To tell the truth, although the Taibai-1 reconnaissance satellite has been sent into the sky, its performance is not satisfactory to Wen Desi, and its resolution can only reach 3.5 meters (the original time and space of the United States in the early 2th century had centimeter-level resolution, claiming to be able to read the headlines of newspapers on the ground). This level of resolution is even inferior to that of civilian satellites in the early 2l century (the "World Eye 2" satellite launched by the "Digital Earth Company" in 209 is said to have an imaging accuracy of 046 meters).

And then there's the issue of longevity. Due to the lack of current electronic signal transmission technology, the resolution of the transmitted image signal is low, so Taibai-1 mainly uses the working form of film, and this kind of spy satellite is basically scrapped once the film is used up, although it has eight return capsules, but it will not take long. Therefore, although its service life is three years, if it is carried out in a high-intensity reconnaissance mission, I am afraid that it will be useless in less than two months.

However, although its performance is not ideal, it is still quite a black technology in this period. The first spy satellite "Discoverer L" launched by the United States in 1959 had a resolution of only 15 meters. Compared with this "Discoverer L", the 3.5-meter resolution of Taibai 1 is already quite advanced, and Mr. Wen feels dissatisfied, just because his vision is too high. In those days, even the worst civilian satellites could reach centimeter-level resolution.

After the successful launch of Taibai-1, a spy satellite, technicians began to collect its operating numbers and make some optimizations to the original backup Taibai-2.

The European battlefield is now a global hot spot, and the orbit of Taibai-1 is naturally set in Europe, and it passes over Europe day and night at a speed of 70 minutes around the earth. It did an extraordinary job, gathering dozens of times more intelligence in a single orbit of Europe than the most seasoned and knowledgeable spy could gather in a year, something that was previously unimaginable (only for the indigenous inhabitants of the plane). The generals of the three armed services and the heads of the four major intelligence departments in China were shocked by this kind of "super spies" and demanded that their units be equipped with this kind of reconnaissance tool.

On the morning of July 2, Taibai No. 1 sent back a set of photographs showing that the warring sides on the Western Front had made a big move. As you can see in the photos, there are a lot more military trains on both sides than usual, and many trains are loaded with something similar to vehicles.

At this time, the resolution of the satellite is not high enough to recognize what it is. However, the coded telegrams of the two sides were not kept secret from the Chinese engineers, and the Chinese soon learned from the cables from both sides that they were ready to break the deadlock with a new weapon.

The British had high hopes for this weapon, and for the sake of secrecy, they called it by a code name - "tauk", which means "water tank". Of course, the water tank cannot be used as a weapon, but this can't hide it from the future generations of Mr. Wen, who knows that this thing is an armored combat vehicle, commonly known as a "tank"

On this plane, the "tank" is certainly not the first time that it has appeared, and China has been equipped with armored combat vehicles long before the Sino-Japanese war. However, at that time, it did not attract much attention in military circles, which is not surprising, and any kind of new thing will be questioned.

Another very important point is that in the Sino-Japanese war, China's armored forces did not get much room to play, because many of the combat sites at that time were mountains, hills and woodlands, which were not suitable for armored combat vehicles. Except for the Marine Corps' L-19ll "Otter" amphibious combat vehicle, which had a very outstanding appearance during the beach-rushing landing, several other combat vehicles became supporting roles, and only earned some face in the street battles to liberate Pyongyang and Seoul.

What's more, what is even more criticized is that the reliability of the chariots is a problem. Often dropped chains, non-combat losses were several times more than in battle. After two months of fighting, less than 3 of them were destroyed by the Japanese army, but more than 450 of them were lying on the streets due to mechanical failures and roads and other non-combat reasons.

Well, in fact, the failure rate of early tanks before World War II was amazing, and the Soviets themselves counted that after their 2 marches of 20 km, more than half of the tanks would lie on their stomachs. Not to mention the tanks of Sandezi, whose Tigers have to hit the streets on average for 100 kilometers. Not to mention the tanks of the First World War, after a battle, half of the tanks can not lie on their stomachs, even if they burn high incense. Compared to these, the table of these Chinese tanks is already quite good.

In fact, in the eyes of the great powers at that time, such a thing as an armored combat vehicle was not such an unexpected thing. Before World War I, many countries had similar research and development plans, but the reliability of the early tracked vehicles, and the frightening failure rate, made everyone have no bottom in their hearts, and they didn't know if the role of this thing could offset those shortcomings, because they were really not sure, so these things stayed on the drawings of the real rooms of various countries for a long time, or the model state, and they were not equipped at all

The table of Chinese tanks also illustrates the failure rate of such weapons, but their role in warfare has been debated. After evaluating the armored combat vehicles in the Sino-Japanese War, military experts from many countries feel that they are a relatively good weapon for street fighting, which can be used as a mobile fortress in street fighting to fully protect their own infantry. At the same time, they are also a good landing weapon, which can effectively break through beach positions. But that's about it. They don't see it as a weapon that can change the war.

Although the armored combat vehicles of this plane have developed faster than the original time and space, the high-level leaders of the ** teams are still very skeptical about how useful it is. This is true even for Germany, which has a lot of military cooperation with China and has introduced combat vehicle technology. Not surprisingly, the military is actually a very conservative organization, especially the old bigwigs, but these bigwigs are in power.

In fact, before the outbreak of World War I on the plane, the major powers had begun to speed up the development and equipment of armored fighting vehicles, both the Allies and the Entente, but because of the distrust of the upper echelons, this weapon did not play a very good role, and everyone basically used this thing as an auxiliary weapon for infantry. Even Germany, which had obtained relevant tactical information from China, did not concentrate on the use of tanks in its hands.

Therefore, for a long time after the outbreak of the war, infantry artillery aviation was in the limelight, but there was no blood-boiling tank battle.

But this regret is finally coming to an end today.

"Did they finally think of fighting with tank swarms until now?" said a helpless smile on his face.

Xin Jie also smiled: "Yes, Mr. Wen." According to our intelligence, they also had no choice before they thought of using tanks to break the stalemate......"

Because the satellites are not very powerful now, in order to understand the situation more clearly, unmanned exploration vehicles are still used. At this time, Wen Desi and others were watching the photos sent back from the front line by the unmanned exploration aircraft.

The armored combat vehicle used by the German army is the Chinese Type 2 192 "Wolverine" tank, which is the magic modification of the T8. Germany bought 20 of these tanks from China, and at the same time bought drawings and production licenses. Now on the photo, the number of this batch of tanks that are being assembled has reached about 550, and apparently Germany itself has produced a lot of them.

On the other hand, the Anglo-French alliance is similar to the original time and space. The tanks used by the British ** team look a bit like the Mark type of the original plane, and the number is about 60. And the French are their own Renault PT-17s, which number about 400 units.

"Mr. Wen, now the battlefield of the two armies is still assembling, and according to intelligence, the total number of combat vehicles on both sides will be around 176 to 186. ”

Wen Deji smiled: "Okay, it's a tank battle." Let the observation groups on the front line pay more attention, and in addition to dispatching an unmanned exploration vehicle, we will make a documentary about this battle, which will be a precious historical material in the future, and at the same time a very good teaching material. ”
