Another person slid over, and the two of them were just about to go downstairs when they heard footsteps.

Is that the man on the sentry post? The sentinel is back?The two quickly flashed to the side.

The sentinels were very depressed. They were fine all the time, but just 10 minutes into the two-hour sentry mission, they found out that they had diarrhea!

You can't go anywhere for sentry, especially this building, there must be no mistakes, but it seems a little too uncomfortable to pull the poop into your pants.After all, this is not a war, but an era of peace.So, in the end, the task of shitting outweighed the sentry, and he ran to the toilet on the top floor.

He just came back and walked to the sentry post. Suddenly, he realized that he still had to go!

Seeing that the sentry had just returned and was about to leave again, they knew that the condiments given to the driver downstairs had worked on time when he had dinner with the sentry friend in the evening.

"Come on, we have to go to the third floor."

Instead of taking the stairs, the two climbed into the vent.

From the vent, the two expertly crawled inside, just like drilling steel wire mesh during training.

Although the vents extend in all directions, they are moving forward skillfully.

Finally, at one point, they opened the shutters.

Looking down with the infrared night vision device, the person in the front exclaimed: "There are too many infrared devices here!"

In later generations, infrared alarm devices were widely used in banks, museums and other places, but now, infrared alarm devices have just begun to rise, because digital electronic technology has just emerged, and the technology still needs to be improved.These advanced police reports were transplanted from military technology.

The infrared alarm device has an emitting infrared light source, and the opposite is a device for receiving the light source. When the invisible light source is blocked by the human body, an alarm will be issued.

As long as they know where those infrared rays are, they can deal with them calmly. Apart from trying not to block those infrared rays, they have another method, using their own infrared emitting devices to replace those light sources that would be blocked by themselves!

In later generations, this method is invalid because those infrared rays are coded, but now, these are the most common infrared light sources.

The two took out their infrared flashlights, cooperated closely, and prepared to challenge this strange area.

The two were very successful and finally came to the front of the safe.

Next, their mission is to open this safe!

To open the safe, both of them have received professional training. A general safe can be opened within 10 minutes. If it is complicated, it may take half an hour, or even an hour.

The surroundings were very quiet, only the mechanism inside the safe made a slight sound when it was in motion, and this sound was also very light, as long as it was a little louder, it might trigger the alarm controlled by the sound.

5 minutes passed, 10 minutes passed, 10 minutes passed, and finally, the door of the safe was opened.

Open the safe with a light hand, and take out a thick stack of documents from it. With the help of the infrared night vision device, you can clearly see the words above, Chobham 2 composite armor processing technology, the following This book is the theoretical model of Chobham 2 composite armor, and the next book is the protection test of Chobham 2 composite armor.

That's it!They were very excited.The Messiah bureau has been set up here for a year, waiting for this opportunity now!

A year ago, Hidari accepted the mission of Director Urid and came to the UK. He stayed in Liverpool for a month before coming to Chobham. After that, he began to get in touch with the characters here until two months ago. , and finally bought Thomson, the personal driver of the professor who is in charge of researching Chobham's armor from the Armored Corps Research Institute. This driver can be said to be a close person next to the professor. building.Not every professor will be accompanied by a lot of bodyguards and so on. To be able to assign him this driver is already a special care of the research institute.However, this driver has an unknown hobby, taking drugs!

Therefore, relying on this hobby, the experienced Hidari bought Thomson, and Thomson would sell anything in order to get what he wanted.

And recently, I finally got this opportunity. The Armored Corps Research Institute has successfully developed an improved armor based on the Chobham armor. The results will be reported to the British Ministry of Defense in the near future, and all the information is temporarily in the hands of the professor. In his office safe!

After receiving the news, another professionally trained Hesney sent from China came to the UK with special equipment.

After this period of observation, Hidari finally arranged everything. From the dormitory building next to that building, he flew over in the air, so that he could hide from various security equipment and personnel on the lower floors, enter the air duct from the top floor, and go straight to the In that office, he set up an ambush to find the construction drawings at that time, and figured out the location of the air duct. Just before the materials were about to be taken away, their action began.

Just a few days ago, the strong wind broke the telephone line. In order to prevent a similar situation from happening again, they replaced it with a strengthened telephone line. This type of telephone line can bear the weight of a person!

With a year's time and the recent careful deployment, they just want to steal a few documents, but they know that these documents are absolutely worth it!

Because, this was ordered by President Qusay himself!

All kinds of military industries in Iraq have gradually started to get on the right track, especially the main battle tanks of the army. The T-72 production line of the Soviet Union has been introduced, and the main battle tanks can be produced by themselves.

Among them, the engine of the main battle tank, Qusay introduced the high-horsepower 6TD series, the tank gun was imported directly from the Soviet Union, but the ammunition is being improved, and it is expected to get greater firepower, and the fire control system is from Germany. It has been improved after the introduction, and after cooperation with Sweden, it will gradually realize self-production.However, on a tank, there is one more important thing, and that is armor!

The armor of various countries is kept secret. Even the armor of the T-72 tank, which is said to be armor lined with a layer of sand between two layers of steel plates, is not sold by the Soviet Union. It is imported from Iraq as a whole. Qusay was not satisfied with the advanced armor production process, because his eyes were fixed on the most outstanding armor in the world, and it was also the British Chobham armor that led the trend of composite armor in the whole world!

In particular, Qusay introduced the T-72 production line to develop Iraq's own tanks on this basis. Therefore, now Iraq must have sufficient technical reserves, engines, artillery, and fire control. The rough prototypes already exist. So, it is necessary to overcome the difficulty of the main armor. It is impossible to import Chobham armor from the UK for this main armor. Therefore, it seems that the most suitable thing is to steal it!Qusay doesn't care about the process, as long as the result is achieved, he must get this advanced armor!

Does Chobham's armor really fall into the eyes of President Kusai?With the accumulation of later generations, Qusay certainly knows that this kind of armor is the most suitable choice for Iraq!

Chapter 733 Chobham 2 Armor

The machine gun sent the cavalry to a dead end, and in order to resist the machine gun, the tank was invented. The tank can become the protector of the infantry, relying on its own armor. In order to block the artillery that is more violent than the machine gun, the tank can only be thickened. One's own armor, as well as artillery, will continue to improve their ability to strike armor in order to block the opponent's torrent of steel. This conflict between spear and shield has always been in the development history of the world's armored forces.

However, in this process, the spear has always had the advantage, that is, the armor lags behind the ammunition.For example, the armor-piercing ability of an armor-piercing projectile against homogeneous steel armor is about 5 to 7 times the diameter of its warhead.In other words, a 100mm armor-piercing projectile can penetrate 500 to 700mm thick steel armor.

In the West from the 50s to the 70s, it basically stayed at the level of using traditional single-cast steel. For example, the German Leopard 1 had a frontal armor thickness of less than 100 mm, and the American M60 had a thickness of only about 150 mm. At that time, the way to deal with the opponent's shells was to maneuver.Before the 70s, the West always believed that mobility was higher than protection among the three major elements of tanks, because the level of fire control systems at that time was still very primitive, and the ability to capture and track targets for high-speed maneuvers was limited.Western engines and transmission systems are already very mature. However, with the development of electronic technology and optical technology, the fire control system of tanks began to develop greatly, and it began to have a high hit rate against moving maneuvering targets. Rate, in this way, relying on running fast is no longer enough.

All countries in the world have begun to study composite armor. The so-called composite armor is a sandwich biscuit, in which a layer of special materials is added in the middle of the steel plate.The Soviet Union was the first to use composite armor on the T-64.However, the most successful among them is Britain, an old capitalist country.

In 76, the British successfully developed the "Chobham" armor, which is a composite armor with a multi-layer structure. The outer and inner layers are hard and tough high-quality alloy steel armor, and the middle layer is thick. The bulk ceramic armor plays the main anti-ballistic role.According to sources from the British military, the ability of the "Chobham" armor to deal with armor-piercing projectiles is three times that of the original rolled homogeneous steel armor.

In later generations, the British armor technology has always been leading. Even the German Leopard 2 tank, after going through twists and turns, finally chose the British Chobham on the Leopard 2A4. However, it was later discovered that it was shrunk by the British. .

The composite armor of various countries is an absolute secret, which is related to their basic national defense. Therefore, how thick are the layers of the "Chobham" armor?What is the composition of each layer of armor?Are there any tricks in armor structure and processing technology?These British will never disclose it, which will give hostile countries a chance to disintegrate their own armor.

In later generations, apart from the depleted uranium armor of the United States, Chobham armor is probably the most famous.

However, at present, the Chobham armor has only passed the first generation, and it is flawed. The main reason is that the ceramic material in the middle will produce cracks under high-speed impact, and the crack propagation speed is about several hundred meters per second. , while the propagation speed of the armor-piercing projectile metal jet is as high as 7000 meters per second, and the generation of cracks will not affect its strength.Moreover, due to the restraint of the inner and outer two-layer steel plates and the solidification of the intermediate binder, the ceramic powder formed by the impact has no "escape channel", and "opposes" the metal jet to counteract the metal jet.As a result of the combined effect of the two aspects, ceramic materials have become masters against armor-piercing projectiles and missiles, but the effect against low-speed kinetic energy projectiles such as tail fin shelling and stabilizing armor-piercing projectiles is very poor.

Therefore, when the first generation of Chobham armor began to be produced on the British Challenger 1, the British Institute of Armored Forces Research began new research and development, considering how to deal with the new mainstream armor-piercing projectiles. Finally, in this year's At that time, breakthrough progress was obtained.

The British have found a way to deal with armor-piercing bullets, that is, cut it off!

The new Chobham armor consists of 6 layers, the outer two layers are steel plates, the middle two layers are advanced ceramic plates, and the inner two layers are steel plates.The ceramic plates in the middle are divided into pieces and placed in a slightly larger outer sandwich envelope, with rubber strips on the sides.When the tank is hit by an armor-piercing projectile, the outer two layers of steel plates first slow down the speed of the projectile core. When the projectile core hits the middle two layers of ceramic plates, the two layers of ceramic plates slide back and forth at the same time after the collision to make the projectile core move. When the direction is changed, the bullet core can even be cut into several sections, the kinetic energy of the damaged bullet core decreases sharply, and the remaining energy is quickly absorbed by the two inner steel armor plates.

This is just a principle, and a complex theoretical model is required, as well as a large amount of experimental data. The hard work of their entire research institute is contained in those thick reports.

Because those have not been reported yet, they have not yet become the key protection objects of the military. For example, the initial Chobham armor, the Soviets tried their best, but they did not get it. However, the Messiah Bureau was very lucky.

This is related to the main force of the British armored forces for the next 20 years, the prototype of the composite armor of the Challenger 2, the new theory of the Chobham 2 armor that can resist the attack of armor-piercing bullets, all the secrets, on this ordinary night, It fell into the hands of two foreigners.

After getting the information, the two were very excited, and immediately left here according to the way they came just now.

Thomson, who was outside, had already checked his watch several times, and finally saw the two people coming out of the dormitory building again. He immediately started the vehicle, carried the two people, and left here.

"Where are we going now?" Thomson asked.

"Go to Southern Cross Street," Hidali said.

"What about my pay?" Thomson asked.

"The reward will be given to you at the crossroads." Hidali said.One after another, Thomson has been given nearly 100 pounds. This time, after such a big event, Thomson asked for [-] million pounds, and Hidari agreed.

Another vehicle from the Messiah Bureau was already waiting at the cross street. Hesni got out of the vehicle first and picked up a heavy suitcase from that vehicle, which was a reward for Thomson.
