"Develop an ultra-light large-caliber gun?" When Liu Yijiu proposed this to relevant experts in District 5, Chen Yang, who was originally responsible for tank gun design, couldn't help but feel a little confused.

Do you need ultra-light large-caliber artillery on the tank?

Even Qian Dayong, Jiang Ming and others are somewhat lacking in this project.

"Director Liu, this should be the 2983 Factory, right? They are a unit specializing in the production of cannons, and they are also our sequence. Over the years, they have made a lot of achievements in the research of cannons. Even our tank guns have begun to transfer technology to their side." Qian Dayong reminded Liu Yijiu.

Designing ultra-light cannons should be the matter of the gun factory.

Liu Yijiu was speechless and could only go to find people from Factory 2983.

Factory 2983 has expanded a lot in recent years. From the production of mortars in the self-defense counterattack against Vietnam, and then to heavy artillery, Liu Yijiu injected a lot of funds and equipment into it. At the same time, he has brought a lot of technical designers in other artillery factories.

Therefore, this artillery factory can be said to be the cannon design and production unit with the strongest technical strength in China.

If people were not poached, they would not be integrated by the Ninth Academy, mainly producing tank guns from Longwei, and 155 heavy grenade cannons were produced, and a series of new guns such as near-defense fast guns used in missile battleships were studied, and even 203 mm heavy guns were produced.

However, Liu Yijiu did not attach too much importance to cannons.

Therefore, Factory 2983 is not a unit that he cares about.

This time he went to the artillery factory in person, and asked Lu Ruixiang and other leaders to pay great attention. Director Liu would definitely not enter their factory without any trouble.

When Liu Yijiu was coming, Lu Ruixiang personally asked whether something happened to the cannons produced by their factory again, or that there was a problem with the previous production, or that the people in their factory did something wrong, which made Director Liu unhappy and prepared to rectify the factory.

Director Liu does not attach too much importance to artillery. Everyone knows him. He prefers precise strike missiles. If it is not for cost reasons, it is estimated that the domestic army will be equipped with various types of missiles, and artillery will become history.

You know, there have been too many things in the 2983 factory.

A comprehensive inventory showed no problems, and no production quality accidents occurred. People in the entire factory, even the children of cadres, were restricted, and there were young people who were going against the will of heaven. Even parents were fired, and no one was making a fuss, and there was no bullshit in the local area.

The large number of orders for Dragon Guard tank guns and production orders for other military guns have left this factory without any civilian products business, and there is no chance of making mistakes at all.

Since there is no problem, Director Liu comes, it means that they may have a new task.

Knowing that Liu Yijiu didn't like the grand show, Lu Ruixiang did not arrange for anyone to greet him at the door. Only he and chief engineer Tian Deming were waiting for Liu Yijiu's car at the factory gate. After greeting each other, he took Liu Yijiu to the conference room. There was no vain and reported directly to the work.

"Director Liu, our 2983 factory is currently in good development momentum. When we received the increased production of tank guns some time ago, other production tasks such as 155mm grenade cannons and 203 heavy cannons have all delayed the progress. At present, the work of 57mm high-level dual-purpose fast cannons has increased efforts..." Lu Ruixiang reported to Liu Yijiu.

Liu Yijiu did not listen to this and directly waved his hand to interrupt their work report.

"You have done these jobs well in recent years, and the development momentum of the artillery factory is also good. However, you cannot blindly expand the production scale because of order problems. Once there are no orders, the business of the entire artillery factory will be reduced, which will cause a series of serious consequences..." Liu Yijiu is not very concerned about Factory 2983 at all.

To be honest, if it weren't for the high cost of missiles, he really didn't like guns.

After all, in the modern war, although the power of cannons is still strong, it cannot be compared with missiles.

This thing requires large-scale cluster artillery bombardment, and saturated bombardment is only effective. It is the best to use in large-scale wars.

With the development of human science and technology, war situations are constantly changing.

Long-range precision strike is the main means of development, and then precise firepower support is used for tanks and armored vehicles.

The cannons used in clusters are assisted by satellite systems in modern warfare, and various reconnaissance methods are emerging one after another. Even artillery reconnaissance radar can infer the location of local artillery positions based on the movement rules of the shells. As long as long-range fire support is invited to the rear, three or two missiles can destroy the entire artillery position.

Therefore, Director Liu did not appreciate the cannon.

The accuracy and maneuverability of the cannons are not too strong. In order to improve maneuverability, there were finally self-propelled cannons. Even each cannon is equipped with radar and automatic fire control system, which is not much different from a tank.

However, if the cannons can have faster deployment capabilities and super maneuverability, and are used for fire support when conducting airborne and mountain combat, and then evacuate after attack, the cost is much lower than that of short-range missiles.

Compared with long-range supported tactical missiles, the cost of this thing is basically negligible.

Similarly, if the weight of the gun is reduced, the weight saved on the tank can also be increased to the armor, or used to reduce the burden on the power system, and it is also very good to have a stronger power system, faster speed and longer battery life.

The technology required by Liu Yijiu's automatic firepower platform has gradually become possible in the development of the Ninth Academy and domestic science and technology in recent years. Large-caliber guns can have a range of more than 20 kilometers, and use rockets to extend the range, and can reach more than 30 kilometers.

If the cannons from Factory 2983 were brought up, the range would be nearly fifty kilometers!

This thing can be used on automatic firepower platforms and is used as the main long-range support weapon. It is definitely more cost-effective than missiles, or it can be made into guided shells...

"The purpose of this time is mainly for cannons. I need a cannon that can fly, a heavy cannon that can be used for airborne, mountain combat, etc., and can be used for rapid deployment. It is very light in weight but has unabashed power! The caliber cannot be less than 152 mm, the weight cannot be higher than 4,000 kilograms, and the range cannot be less than 30 kilometers..." Liu Yijiu got to the point directly.

He came for this.

Liu Yijiu's request immediately shocked everyone.

Isn't this a joke?

Such heavy artillery can not weigh more than 4 tons. Is this possible? The current 155 artillery cannons exceed 13 tons.

Even if you want to install this on the Destroyer tank, you can't reduce the weight.

Especially at such weight, such high performance is required!

There is no such possibility at all.

"Director Liu, this is impossible. We have been working hard to reduce weight. In the current environment, the rapid deployment of heavy artillery is not very mobility. Although Zhijiuyi's carrying capacity is strong, there is not much equipment in China. If we want to transport the cannons, shells and even artillery soldiers quickly at one time, there is basically no possibility... Therefore, we can only reduce weight. At present, there is basically no possibility of achieving such power under such a weight..." As the chief designer of the artillery factory, Tian Deming said to Liu Yijiu with a bite.

He wanted to refute Liu Yijiu's unrealistic demands.

If this kind of gun is developed, it will definitely be beneficial and can even make the performance of self-propelled guns more outstanding.

The problem is that this requires very advanced supermaterials to support.

Titanium alloys and aluminum alloys are the most likely situations under the current circumstances. The problem is that after countless theoretical verifications, they have not been able to achieve the power of a 155 grenade cannon, and they are even at risk of explosions.

As a result, the project basically fell into a state of stagnation.

They hope to develop super-range cannons with larger caliber and longer tubes.

"How could you know that it was impossible without doing it? Ten years ago, could you believe that Factory 2983 could reach its current scale? Can you believe that these heavy artillery can be born in your hands?" Liu Yijiu looked full of contempt. "Technology is developing, technology is improving."

"Director Liu, we have studied this ultra-light cannon before. But there has been no breakthrough in recent years. I know you want to talk about titanium alloys and aluminum alloys, because the super-hard aluminum alloy used on our tanks is strong enough and its weight is less than one-third of that of steel. However, after these materials are constantly bombarded, they will affect the quality of the entire cannon..." Lu Ruixiang saw that Liu Yijiu was about to get angry, so he could only take a deep breath and then explained to him.

Liu Yijiu really didn't expect that Factory 2983 had already explored this aspect.

The xm777 joint light 155mm howitzer is the world's first ultra-light heavy artillery. The joint project of the US Marine Corps and the Army, this light cannon has a combat weight of only half or even less than that of the m198. It also has more auxiliary equipment, but its power is not worse than that of the m198 howitzer, and its various performances are stronger. Even the number of soldiers operating is reduced to 5.

You should know that this kind of gun is a cannon that uses titanium alloy and aluminum alloy, and the delivery time is in 2004!

Now, the US military does not even have such an idea.

After all, missiles are the mainstream.

The function of artillery has basically become less obvious.
