1959: Carrying the achievement system, she rolled

In addition, he only focused on attacking and ignored defense. Although he was not Yu Ya's opponent, he could already make Yu Ya suffer.

At that moment, everyone cried with joy, as if they saw a better life beckoning to them.

Even the look in Gu Shiyan's eyes when he looked at Lao Wu changed from disdain at the beginning to admiration.

When Du Yimeng and Wen Yan were discharged from the hospital, they found that a large group of people had come to see them off, and they were all there to see off Lao Wu.

The look of reluctance and almost tears shocked everyone. They also knew that Lao Wu would compete with Yu Ya every day, but they didn't expect it to have such an effect.

Some people sincerely hoped that he would stay, especially the head of the security department, who even said that as long as he was willing to stay, he would be willing to give up his position and become his deputy.

This is definitely the highest level of retention!

The head of the security department said: "You have to stop! He's the one who got beaten the most by Yu Ya!"

"Thank you all for your kindness. I will come to see you when I have time!" Lao Wu looked into the crowd, but there was no sign of Gu Xiaoai. A trace of loss flashed in his eyes.

However, he immediately stood up again. He did not gain nothing. While he was able to withstand the beating, he had become friends with Gu Xiaoai.

As long as he uses the hoe well, what city wall can't he dig down?

……

After Du Yimeng finished her confinement, she continued to work and handed the child to Yu Lang. This was the time when the greatest benefit of being a good wife was reflected.

Wen Yan, on the other hand, works and takes care of her children at the same time, mainly because her job is relatively leisurely.

During her confinement period, Director Song also arranged for someone to take care of her, but after the confinement period, she dismissed the person who was taking care of her because she felt that she could not always occupy the institute's resources.

Xiao Mu's younger brother is named Qin Zirong, which means unyielding and tenacious. If nothing unexpected happens, the couple will still cultivate their child into a scientific research career.

……

Time flew by in the busyness, and soon it was September 68. The institute was particularly lively that day.

After a series of tests, the Type 103 was declared a success and was officially named the Type 68 main battle tank.

The total combat weight is 43 tons, and this weight was maintained through the efforts of all the scientific researchers in the institute. It can be said that everyone has put in a lot of effort.

Reducing tank weight means improved mobility, adaptability to more combat environments, reduced transportation, and less logistical pressure.

They also had to put in a huge effort. The materials issue was something that nearly broke Qiao Gong because, given the current state of technology, some lightweight and protective materials simply weren't available.

Fortunately, their efforts paid off and they got the results they wanted.

The Type 68 main battle tank was developed from the Type 64 main battle tank, but only the structure and appearance are somewhat similar, while other devices have been improved or replaced.

The Type 68 main battle tank should be the first main battle tank in history powered by a gas turbine.

Its engine was modified from an aviation gas turbine engine. After a series of improvements, it became the engine they wanted: small size, high power, fast starting, light weight, high reliability and easy replacement.

Compared with diesel engines and gasoline engines, gas turbines have unique advantages. While occupying the same space, gas turbines can greatly increase their power.

In this way, the tank's various high-speed performance and thrust performance are greatly improved, and the tank's handling performance is optimized.

And under low temperature conditions, the engine can be started quickly and reliably.

Of course, it also has its shortcomings, such as extremely high fuel consumption, but if you want the horse to run, you have to feed it grass, which is unavoidable.

The firepower of the Type 68 tank is still equipped with a 125mm smoothbore gun as the main gun, a 7.62mm machine gun and a 12.7mm anti-aircraft machine gun.

In addition to firing conventional artillery shells, the main gun can also fire anti-tank missiles.

After the unremitting efforts of Engineer Liu and his team, with the support of the booster engine, the range of the anti-tank missile has reached four kilometers, and it only takes 9 seconds.

Such a short time means that the target can be hit in the blink of an eye, leaving the enemy nowhere to escape.

Of course, the improved fire control system played a crucial role in this.

With advanced fire control components such as laser rangefinders and ballistic computers, tanks can lock onto targets in the first place.

Anti-tank missiles have enormous armor penetration and lethality, especially the armor penetration thickness can reach 600 to 650 mm.

However, its cost is also very high. The price of an anti-tank missile is about 5,000 yuan, which is equivalent to Du Yimeng's two-year salary.

When it was built, everyone was excited, except Director Song, who was trembling all over. This wasn't a missile, it was money!

Later, he kept hypnotizing himself, thinking that good things are not cheap, and cheap things are not good, and only then did he calm down.

As for the tank's protection capabilities, the front of the vehicle body uses composite armor, with the outer layer being steel plates and the middle layer being fiberglass and steel plates, as well as new materials.

In addition, the front half of the turret and the upper front armor of the vehicle body are equipped with reactive armor, and its sides are protected by rubber track skirts.

With several layers of protection, it is no longer a tank, but a mobile fortress.

It can be said that its defensive capabilities are enough to make it surpass all firepower in the world.

The transmission followed Qin Chulong's suggestion and had a manual transmission with five forward gears and one reverse gear, which was a perfect match for the engine.

As for the alarm device that Du Yimeng strongly requested to add, it uses the laser emitted by the laser rangefinder and laser indicator to respond and send out an alarm signal.

The reason she made such a request was because the alarm device on the tank was equivalent to an early warning system.

It can provide quick and timely alarms when the tank is threatened so that the crew can take countermeasures, which can greatly improve the tank's survivability on the battlefield.

Thanks to their efforts, the Type 68 tank became the most advanced tank in the world. Whether it was its firepower, mobility, or protection, it was a perfect masterpiece of technology at the time.

Director Wei personally brought people to the research institute. Today, he abandoned his previous serious image and always had a smile on his face.

Commander Cai and Li Saichang were also traveling with them. Commander Cai had a stern face at first, but as Du Yimeng introduced the Type 68 tank for a longer time, he could no longer maintain the seriousness on his face.

Li Saichang had no burden of being a commander at all. He had his mouth wide open and a look of shock on his face from beginning to end.

There were only four of them in Director Song's office, and Director Wei and the others were afraid of losing their composure and being seen by others.
