The significance this time is even greater than the significance last time.

The last test was a long-range launch vehicle, which meant that Han was able to project mushroom bombs into the enemy's heart at the last moment on its own territory.

However, this kind of long-range launch vehicle is liquid. Before launching, it needs to refuel and carry out a series of cumbersome procedures for takeoff. At the same time, because of its huge size, it is deployed in silos. Therefore, once the enemy Decided to launch an attack, the targets of the first wave were these missile silos.

Only a huge number can survive the first wave of strikes and carry out a nuclear counterattack. Both the Xiong State and the Eagle State have a large number of intercontinental ballistic missiles, but Han State does not have it. Han State only solves the problem. The terrible military expenditure brought about by the deployment is not something Han can afford.

Therefore, the Han country also needs other assassins to carry out a nuclear counterattack at a critical time. This is the submarine-launched ballistic missile.

In the vast ocean, the submarine carries ballistic missiles and sails silently under the water, waiting at any time. Once received the order, it can launch its own missiles. The enemy is unprepared, so that it can Form a evenly matched nuclear deterrent.

Any major nuclear power has submarine-launched missiles, and Han must also have them.

Last time, Qin Guan once met Huang Lao, gave a quick glance, and left some suggestions. His remarks about selling the Dongfeng-3 missile shocked the missile experts.

And Huang Lao is the person in charge of Julang-1.

When Qin Guan came to the Naval Command, a meeting for this important experiment was being held.

In the past, Qin Guan had not participated in these studies. Qin Guan's hands had touched the equipment of the sea, land and air, but there was still a place where he was restricted, and that was ballistic missiles.

Ballistic missiles, this is a weapon of the country, especially the current submarine-launched missiles, which are absolutely highly classified, and Qin Guan is not qualified to contact them.

At the same time, Qin Guan also knows that this project has been going on for more than ten years, and many people's most precious youth have been dedicated to this project.

In 1965, the nuclear submarine project was launched, and in 1967, the submarine-to-surface missile project was launched. This is another major decision concerning national defense security after the successful development of the atomic bomb.

The arduous journey began. In order to keep secret, this project was carried out on the grassland. The conditions are extremely difficult. During those special and turbulent years, they swayed their youth and sweat on the grassland. Later, the arrival of Huang Lao put the team on the right track. The development of the missile was in extremely difficult circumstances. Next, it develops little by little.

Now, in the conference room, everyone has a smile on their faces. Huang Lao is there, looking at Qin Guan, and said: "Mr. Qin, our underwater launch is about to begin. I have to thank you North Industries Corporation. Our great support!"

Qin Guan had already forgotten about his strong support. Now that he heard Huang Lao say this, Qin Guan just remembered. At that time, he patted his chest and gave them priority to get the computer of Hanxin Technology and the inertial navigation system. , Qin Guan also provided some help.

Now that Huang Lao said this, Qin Guan immediately became polite: "Huang Lao, these are what we should do. For the national defense cause of the motherland, we only provide some meager strength."

"It's not a meager power." Huang Lao said: "We have acquired more than one hundred computers, which has greatly accelerated our development. The ballistic calculations we need most are used after the introduction of this computer. In half a year, the data that had not been calculated in the previous seven years was completed!"

When launching a missile from a silo, the data is known, but when launching on a submarine, that’s not the case. The submarine itself moves. When going out, the sea water also moves. Various conditions must be considered. To have a complex model, the amount of calculation is quite large.

In the past, I didn't calculate it for a long time, and it troubled everyone for a long time. Now that the advanced computer system is available, it is easy to calculate again.

"Oh, it turned out to be so, then we are still very proud." Qin Guan said: "However, after hearing the news of the launch several times, it is always delayed a lot. Is it difficult?"

Historically, Julang-1 was launched in October. There were many technical problems that had not been resolved. With the help of myself, it was still about the same time in history. What does this show?

Have you encountered a problem?

"Mr Qin, you are here to test and teach us." Huang Lao said: "Originally, we were able to launch at the beginning of the year, but seeing the rapid development of our electronic technology, we finally made up our minds The electronic system has been completely replaced and has directly entered the era of integrated circuits. This update has delayed the progress."

Qin Guan was suddenly surprised.

The development of the Julang-1 began in the 1960s. At that time, it was still the era of electronic tubes. When developing this missile, it was necessary to greatly reduce the size. Therefore, the related factories are all in Work hard to reduce the length by one millimeter.

However, electron tubes and transistors are limited in how they can be reduced. Only in the era of integrated circuits can the volume of electronic systems be greatly reduced, and at the same time, the performance has also been greatly improved.

At a time when electronic technology is developing rapidly, the electronic equipment in the Julang 1 bomb has actually been researched and developed. At this time, they dare to overthrow it and start over, and they are also taking great risks.

The development of Hanxin's technology has led to the tremendous progress of the electronics industry in the entire country, and the electronic technology used in national defense is naturally following the development.

"Mr. Qin, let’s tell you that, our JL-1 internal bomb-borne computer now uses the Hanxin-2 chip specially for military reinforcement. We are very proud of its computational efficiency." Continue to say.

That's for sure. If the civilian chip is used for reinforcement, it must be quite powerful, and its frequency is already over 100M.

If it's something else, maybe you have to worry about electromagnetic interference, but the submarine-launched missile is originally underwater, and this is not a problem.

Ballistic missiles require a lot of calculations. If there is no qualified computer, it is really a problem.

Of course, military chips are different from civilian ones. Special military chips are also being developed in 114.

"Everyone, I did not attend the previous meeting. Everyone must have considered the entire launch process. I just want to remind us whether there will be more bystanders during this launch? At that time, we have to think about it. The response plan."

When Qin Guan said that, all the admirals present suddenly became serious.
