Chapter 490: Blooming in unison!

Du Haisheng never thought that there were more than 100 masters in the Foshan martial arts industry who sneaked into Shanghai. What surprised him more was that the host behind him turned out to be his old acquaintance - Lin Tianxu and Wang Jiadong!

He thought that Ma Yongzhen and others had hurt the two guys last time, so that he didn't dare to step into Shanghai again, but he didn't expect that the two guys would not be killed by the white hurricane waves in the sea, and he also went to Guangdong. He met the boss of Foshan over there and became someone else's son-in-law. Fortunately, he was lucky. It's really good.

However, in the information collected by Duan Tianhu, no trace of Lin Tianxu and Wang Jiadong was found in Shanghai. Wherever it is possible to hide, special personnel have been sent to monitor.

"Well, these two kids are smart!"

After seeing off Duan Tianhu, Du Haisheng sat on the rattan chair, looked at the gloomy sky outside, and sneered in his heart.

The current Shanghai city is as solid as gold soup. Lin Tianxu and Wang Jiadong also know that even if the current Shanghai city is easy to enter, it is absolutely not easy to get out.

In particular, Du Haisheng's power has controlled the whole city of Shanghai, not to mention more than a hundred people, even more than a thousand people, is still not enough for the other party to deal with.

Once they fail this time, it is impossible for them to escape from Shanghai again. Duan Tianhu said that it was also an excuse not to find the trace of the two.

But Du Haisheng felt that these two people would definitely appear, and now they are just hiding in a place not far from Shanghai City, secretly paying attention to every move here. It's hard to say where it is.

The nearest places to Shanghai, Anhui, Nanjing and Yuhang!

And Anhui and Nanjing are both in the north of Shanghai City, and Foshan is in the south of Shanghai City. It is impossible for them to go around these two places, so the only possible place is Yuhang.

But the key to the problem is that the Central Army in Yuhang and the current 18th Army are already intolerant, and he doesn't have much business there. If he wants to investigate, it is still difficult.

The final decision was that he asked Duan Tianhu to find a safe and reliable person to go to Yuhang in person. As long as he could grasp the traces of Lin Tianxu and Wang Jiadong, the two of them were aggressive, and they no longer had any threat to him. The last time they were like bereaved dogs. This time, they were not even prepared to give a dog's life. The two stayed.

As for the lurking martial arts masters in Foshan, Du Haisheng did not take any other action except to let Zhou Wenshan and Duan Tianhu's intelligence services monitor them 24 hours a day.

Everything is under control, and he is not worried about what will happen in the middle!

While he was in charge of everything, there was good news from the five-person ordnance manufacturing company. The armored car series led by Johnson's public relations has overcome some problems such as steel plate, brake system, cab frame system, etc., and is under the final overall structural design, and even, as a military strategy, relatively Important armored personnel carriers and infantry armored fighting vehicles have entered the final sprint stage.

As a special forces king in the 21st century familiar with history and military affairs, Du Haisheng has a clear understanding of the importance of armored vehicles in World War II.

At the end of World War I, the British were the first to develop tracked and wheeled armored transport vehicles. The car has light armor and a machine gun, which can carry 20 soldiers. Although the armor on the car can protect the soldiers in the car from bullets, the infantry accustomed to migratory combat still call the first batch of armored transport vehicles "sardines" and "coffins with wheels".

In August 1918, a chariot battalion of the Seventh Army of the British Army used an armored transporter for the first time in Warsaw. Twelve armored transporters burst into fire and attacked the enemy. The German officers and soldiers were extremely frightened and fled in panic. British soldiers then jumped out of the car and occupied German positions, and other countries' armies also discovered the military value of armored transport vehicles.

Armored vehicles are classified according to different functions, including armored personnel carriers, infantry fighting vehicles, armored command vehicles, armored ambulances, armored reconnaissance vehicles, etc.

Armored personnel carriers are mainly vehicles that transport soldiers in war and can also transport supplies at critical moments.

The infantry fighting vehicle and the armored personnel carrier are similar, but the firepower is more fierce, the steel plate is also much thicker, the protection ability is relatively stronger, and it is also equipped with strong firepower. Soldiers can also fight when sitting on it and cooperate with other infantry to carry out strategic strikes. The significance is self-evident.

And armored ambulances, armored reconnaissance vehicles and armored command vehicles have also greatly improved the mechanization and combat agility of the army to a certain extent.

Due to the current limited technology, Du Haisheng does not require armored vehicles to reach such a high level. As long as he can adapt to the current war, it will be a little better than now.

Johnson himself is a specialty in this regard, and under his communication, he secretly recruited more than a dozen technical talents from Germany, so the research and development speed of armored vehicles has been further improved.

Since armored personnel carriers have made substantial progress, it means that all the progress of armored vehicles will be greatly improved. During World War II, the Republic of China was almost blank in this regard. Everything depends on the assistance of foreign allies, and its own armored vehicles are not at all at all, even in World War II. In the early stage, many Chinese soldiers did not know what these big people were.

Du Haisheng's infantry fighting vehicle can carry a total of 30 people, ten more than the 20 in the first war, which made him very satisfied and excited.

The news brought by Johnson made Du Haisheng very excited. As long as this kind of combat vehicle can be developed and produced, the battle of the Iron-blooded Eighteenth Army and even the whole Republic of China will be greatly improved.

However, Du Haisheng also knows that it seems to be beyond the ability to develop and produce all these strategic equipment on his own. After all, this requires an extremely large amount of funds to support, and after all, he is a person with limited funds. Even if he has a considerable accumulation of property now, it is also fundamental. I can't stand such a toss.

Especially for the production line of armored combat vehicles, the equipment required is a huge resource. Du Haisheng feels that it is necessary to discuss with others for joint development.

At the same time, Johnson has another exciting news for Du Haisheng, that is, a lot of progress has been made in the research and development of tanks.

Although tanks are also a kind of armored vehicles, they are independent because of their combat intentions and strategies. Compared with armored vehicles, tanks have stronger protective effects, thicker steel plates, and have two kinds of large and small calibers. According to the combat strategy, they are divided into light and heavy tanks, firepower and armored vehicles. It's not the same as tanks.

And the heaviest in the world is the rat tank built by Germany during World War II.

It is three or four times heavier than a modern tank, reaching 188 tons. It is 9 meters long, 3.66 meters high, 3.67 meters wide, and 200 mm thick frontal armor. It can climb a 30-degree slope, cross a 4.5-meter trench, climb a vertical obstacle of 0.72 meters, and a depth of 2 meters. There are 8 crew members. The tank is equipped with a 150mm artillery and two machine guns. Light tanks are only 10-20 tons, mostly amphibious tanks, equipped with 85mm caliber artillery, mainly used for airborne or marine use.

At present, the most advanced main battle tanks in the world are mainly developed after the 1980s. Their representatives are: Soviet/Russian T-90, T-80, American M1A, M1A2, Chinese Type 99, German Leopard 2, Japanese Type 90, British Challenger 2, French Leclerc Er, Mekava 4 in Israel, Ram in Italy, etc.

Du Haisheng's armored tank research and development company is mainly aimed at heavy tanks of about 50 tons, using 110mm large-caliber barrel. At the same time, two types of light and medium-sized tanks were developed. Although it is impossible to develop Chinese Type 99 tanks according to the current technology, Du Haisheng still stipulated the hard indicators. Especially in terms of mobility, it is even more strict.

On the whole, the five-person ordnance manufacturing company has made gratifying achievements in a series of research and development, including heavy weapons, gunpowder, armored tanks, etc. Only warships and aircraft have made slow progress, but Du Haisheng also knows that these two aircrafts are relatively easy to say, especially warships. The system is complex and the structure is as tedious. A huge project.

Moreover, the talents needed for research and development, various materials, power and other systems need to be cooperated by extremely professional companies, and its own five-person ordnance manufacturing company obviously does not meet such requirements now.

What's more, the cost of building a warship and an aircraft is not small, and it is impossible to complete it in a short time.

Therefore, Du Haisheng is not in a hurry. After all, fighting on the battlefield in China, the ground is still the king. For example, the tanks developed by himself and the anti-aircraft guns developed by the Heavy Weapons Development Center will pose a great threat and deterrent to Japanese aircraft, and the air control is not very urgent.

With the progress in the development and production of armor, tanks, gunpowder and heavy weapons, Du Haisheng also knows that the territory of the arms empire in his heart will gradually become clear...
