Liu Yijiu, who is not clear about the history of artillery development, also studied artillery, but he did not know that whether it is the Chinese AH-4 ultra-light 155mm howitzer or the American M777 ultra-light 155mm howitzer, the barrels are actually made of conventional ultra-hard gun steel.

Although titanium alloy is advanced enough, its material characteristics determine that this material cannot withstand ultra-high pressure at all.

The longer the range of the cannon, the higher the chamber pressure required.

Only higher chamber pressure can increase the initial speed, so that the shells can fly in the air for longer.

This is also a problem with no choice. He didn't know the specific design plan of the cannon that was already considered antique to him. Otherwise, as long as the gun stand structure is solved, there would be no problem. The weight of more than three tons is relatively light.

This is not an electromagnetic gun, but a gun that uses conventional actions.

The principle of the electromagnetic gun is completely different from that of conventional guns. At the same time, the shells and guns of electromagnetic guns work differently.

"Director Liu, can we take this project? I think in the current environment, there is no need to do it, and the cost is really high. Unless our troops are equipped with a large number of helicopters... the cost is too high, and even our 203 guns, the military has only purchased a small number of self-propelled artillery, not to mention higher-cost self-propelled artillery. Even the research on self-propelled artillery of the 203 heavy guns has slowed down." After the fewer people, Lu Ruixiang asked Liu Yijiu.

According to their ideas, if possible, there is no need to do these projects for the time being.

The lightweight design of guns does require research. However, the lighter it is, the better the materials needed.

Ordinary gun steel only costs a few dozen yuan per kilogram and tens of thousands of yuan per ton. The gun produced is of good quality, but the cost is absolutely cheap. At most, the movement is not so flexible and cannot be deployed quickly.

"You forgot the purpose of our Ninth Academy's existence? It is not only to explore the development direction of weapons and equipment, but also to use future war situations as the research and development direction of our weapons and equipment. We are not for the current military construction, but for the future! Your idea of ​​studying this Chinese super light gun is very correct." Liu Yijiu does not think that designing weapons requires the current domestic economic level.

After all, the domestic military system has two systems.

One is for the development of active equipment, while they are conducting forward-looking exploration and research.

Funds will be allocated only if the country needs projects.

The funding is too small to take into account all aspects.

The domestic research principle is to produce one generation, study one generation, and pre-research one generation.

The main task of the Ninth Hospital is to study one generation and pre-research one generation, and to carry out production while researching, mainly for sample production.

When they succeed in their research, they will transfer production. They will not be equipped in China, but export it, or use it for technical reserves, and then continue to spend money to explore and study experiments in the direction of the next generation. The results of these projects are used to improve the performance of the previous generation, and use the stimulation effect of the project on surrounding fields to stimulate related fields to quickly develop towards the front.

When the development of related fields has not been resolved, you can only stop and conduct horizontal extension research.

"So, many times, we cannot only consider the present moment! Although under the current development of war, the role of artillery will become worse and worse due to problems such as mobility and accuracy, and will gradually be eliminated, but you have to consider how much the cost of a missile is currently!" Liu Yijiu himself does not like artillery because of this reason.

As the earliest thermal weapon in the world, the development of artillery has always occupied a very large proportion in the military industry.

Even when the 22nd century is about to enter, electromagnetic guns are still in play.

This is no different from the solid bombs fired in ancient times. They all rely on the kinetic energy carried by the shells to produce effects.

Of course, the use of armor-breaking and killing of shells is also the research direction of electromagnetic cannons.

"According to the current military development, during combat, the first wave is long-range strike, which is mainly long-range missiles strike the enemy's air defense system and command system. The second wave, after the enemy's air defense capabilities are cleared, air bombing will be bombed. Until the third wave, helicopter troops will cooperate with armored troops to raid, and then artillery and infantry will advance..."

Liu Yijiu knew very well about the combat mode of future wars.

Of course, the role of artillery is actually a bit useless.

Artillery long-range fire support generally requires saturation bombing. However, with the advancement of technology, cluster charges and large-scale position warfare have decreased, or even disappeared. Urban street warfare is the mainstream, and fire support is to rely on long-range missiles, individual missiles, or nearby tanks and armored vehicles to conduct reinforcements.

This makes the status of artillery a little awkward.

Drag-and-drop, before you reach the designated position, the war ahead has ended, or both sides are in a stalemate, you can't kill even your own!

Only self-propelled cannons can keep up with the pace.

Cannons are mainly used for tough battles.

"Under the current situation, the role of artillery and status are very awkward. Although we had a fight with Vietnam ten years ago, and our heavy artillery made them unable to raise their heads, the Iran-Iraq War has already shown the clues of modern warfare. Missile attacks hundreds of kilometers away, precise strikes on tank clusters by fighters, bombing key targets..."

Although the Iraq-Iraq War is a garbage battlefield for two people using old tactics to fight high-tech wars, we can find out from this that the trend of the war has completely changed.

China's self-defense counterattack against Vietnam is also very backward in tactics.

Vietnam is not a military power, and its war mobilization capabilities are not as strong as China. It is just to give China experience.

Unfortunately, there were not many high-tech equipment in China at that time.

The J-8 II has not been made yet, and the J-11 and J-11 have no chance to show their faces. Even the Z-91 has not found a chance to fire.

Only, the 336 rocket launcher and cloud bomb were scrapped by an elite Vietnamese division hundreds of kilometers away.

"So, what about the future development prospects of our artillery factory..." Lu Ruixiang couldn't help but feel a little confused.

In this way, the artillery is indeed very embarrassing.

"So we must study to improve the maneuverability of artillery. The missile has a long range, high accuracy, and great power, but it has a fatal disadvantage, that is, it is expensive! Such consumption is not something that all countries can withstand. At present, countries have invested a lot in missiles, but have not cancelled the research on long-range artillery. It is for this reason. Tanks, self-propelled artillery, and armored vehicles are all mobile artillery and have strong defense capabilities... and once towed artillery is arranged, it is very difficult to transfer. Our artillery reconnaissance radar is an obvious example. Once the enemy's artillery position is discovered, it is called for long-range artillery fire to strike..." Liu Yijiu explained.

"So, you asked us to study heavy artillery with lighter quality, fast maneuverability, and even mountain combat for long-term development?" Lu Ruixiang asked Liu Yijiu.

Liu Yijiu nodded.

As long as the cost of missiles cannot be reduced, artillery is necessary.

Even artillery is an important reserve force.

"The cost of artillery is far lower than that of missiles. If we can make the hit accuracy of these artillery comparable to missiles, and move even faster than self-propelled artillery and tanks, the helicopter will be hoisted to a certain area, and then the artillery and ammunition inside the helicopter will be placed in a few minutes to provide precise heavy fire support for the combat radius within a radius of dozens of kilometers..."

This is even more effective than missiles.

This is the prospect and direction of the future development of heavy artillery.

Tian Deming couldn't help but fall into deep thought.

As the core backbone of domestic heavy artillery research, it is naturally clear.

Although artillery is still vigorously developing in China, the status of artillery is indeed very embarrassing.

Although they didn't say it, they also understood that otherwise, they would not have started the research on ultra-light cannons without any requirements. Only such cannons can maneuver quickly and make the design of self-propelled cannons more advanced.

"So, artillery soldiers are not without a future, right?" Tian Deming was very lonely.

"The cost of artillery is the biggest reason for survival." Liu Yijiu nodded. "With the rapid development of missiles, as long as the cost does not decrease to the cost of artillery shells, it is basically impossible to eliminate artillery soldiers in full. You don't have to worry about this."

The US military suffered a loss in the Gulf War, and the cost was too high. The soldiers encountered several militants resisting and called for support from the rear. When there were no tanks or armored vehicles around, they either used missiles to support them long-rangely or dispatched fighter jets. No matter which kind of support, the cost was too high.

Finally, the M777 ultra-light 155mm howitzer appeared.

Because of its light weight, strong power, stable performance, high accuracy, strategic deployment ability, tactical maneuverability and strong survivability, it was used to eliminate the M198 howitzer they were equipped with domestically equipped.

China only began this research when it entered the 21st century, and it was only when the first decade passed and the second decade was almost the same, so it began to be arranged in China.

You know, in that era, China had the largest artillery in the world!
