Range.

Power.

Weight.

Maneuverability.

These are several important parameters for examining the performance of artillery.

While reducing the caliber and weight, it is necessary to increase the ratio of multiple diameters if you want to maintain sufficient power and sufficient range at the same time.

The longer the barrel, the longer the range, and the straighter the trajectory, which is the most basic principle.

At present, it is generally 45 times the caliber. The maximum firing range is between 40-50 km.

If it is possible to increase the caliber to 50 times. Then the range can be increased by 5-10 km.

If it is increased to 60 times the caliber, the firing range can be increased by another 5-10 km.

If it is 75 times the caliber, the maximum range will be more than 80 km.

However, the larger the aspect ratio, the higher the requirements for the manufacturing process.

After all, the body has to resist the effects of gravity. After a long time, the phenomenon of natural bending will appear.

At present, electroslag remelting and self-tightening technology have also developed to the limit.

Especially for large-caliber guns of more than 120 mm, the larger the aspect ratio, the more serious the phenomenon of sagging. Some tanks even require the addition of special support frames.

However, if it is a barrel forged from a hydraulic press of 50 billion tons, then there is no problem.

The topic was accidentally off-track.

Peng Deming seems to have deliberately led the topic to artillery.

In fact, he did not appear alone.

He came with a large crowd.

"This is Wang Bu'an, Chief Engineer Wang. The current head of White Feather Whale Technology. At the same time, he is also at the helm of Tyrannosaurus Rex Industries. ”

"This is Chai Lufeng, Mr. Chai. Vice President of Vulcan Heavy Industries. Artillery specialists. ”

"Hello. ”

"Hello. ”

Peng Deming introduced to both sides.

What he brought was the inspection team of Vulcan Heavy Industries.

They had come to inspect the Apocalypse Tank. By the way, it is also necessary to exchange the progress of the development of artillery.

The artillery of the Apocalypse Tank was developed by them.

Almost half of the large-caliber artillery used in China came from Vulcan Heavy Industries.

For example, the aforementioned PLZ45 star gun.

The original design of the Apocalypse tank was a 140 mm gun, which was very demanding.

In the former Soviet Union, it was absolute artilleryism. The artillery will give you as much as you can. I don't care about the cost or anything at all.

Now, however, this kind of thinking is no longer suitable.

The performance should be strong.

The price should be low.

Be useful.

If you can't make it, it's just an ornament. Waste of manpower, financial and material resources.

Anxious for this reason, Wang Buan believes that when necessary, the 255 mm tank gun can also be used as a support firepower - long-distance artillery support.

The current army rabbits do not have heavy guns of more than 155 mm? The 203 mm howitzers have been decommissioned.

The caliber is 255 mm, the ratio of times to diameter is more than 75, and the firing range must be more than 80 kilometers!

As a battlefield support weapon, the effect is definitely good.

255 mm caliber, 100 times caliber, the firing range will be more than 100 km!

This is a very frightening range.

It's almost the range of short-range missiles.

If a bottom-row extended-range projectile is used, the range may exceed 120 km. It can be said that it is invincible in the world.

A 240-mm howitzer across the strait, with a range of only 23 km, is a joke.

The consequence of the short range is that people are pressed to the ground and repeatedly ravaged.

You don't have a chance to fight back.

Can't hit each other.

What can you do?

"Heck, we don't need to study the Apocalypse Tank, let's just study a self-propelled gun. Zhong Hui exclaimed exaggeratedly.

"Don't say it. That's what I'm here with this mission. Chai Lufeng said.

"What task?"

"It is to study super heavy artillery with large caliber, large range and high power. ”

"What's the caliber?"

"More than 255 mm. ”

"How far is the range?"

"At least 80 kilometers or more. ”

Chai Lufeng explained slowly that he had come to Wang Bu'an to discuss joint development.

The focus of research and development is a large-caliber heavy gun with a caliber of 255 mm. Mainly for export. Mainly used for coastal defense. There is a strong demand for this market.

"Haiphong?" Wang Buan asked with some confusion.

"The deep-sea monsters have been very active lately," Chai Lufeng said, "and all countries are a little nervous. ”

"That ......"

"They need a lot of shore defense artillery. ”

"Oh. ”

Wang Buyan understood.

It turned out to be a sin of his own making......

Oh, no, that's how it should be said. It is also a market that he has unintentionally developed.

Originally, I just wanted to plot against a certain country, but I didn't expect that the development of the whole world would deviate a little from the original track. The arms market became active all at once.

Indeed, the monsters of the deep have been very active lately. One moment here and one moment there.

So, what if a deep-sea monster appears?

Navy?

On the Air Force?

What if the Navy is insufficient?

What if the Air Force is insufficient?

Whether it is the Navy or the Air Force, it will take a long time to build. There's no way to do it overnight.

It takes a long time to train pilots. It will take a hundred years to build a full-fledged navy. Obviously, the vast majority of countries do not have such capabilities.

So what to do?

You can't sit still!

At this time, someone said to them, why don't you buy a few hundred artillery pieces to defend against it?

If you can't handle the Air Force, you can't handle the Navy, you can't even handle artillery, right? That's okay. We take care of the training. In just three months, combat effectiveness can be basically formed......

If a deep-sea monster appears near the coast, immediately gather hundreds of artillery pieces to beat it. Maybe you'll scare it away.

Tens of millions of dollars for a fighter. A warship costs hundreds of millions of dollars.

How much is an artillery system?

That's millions of dollars at most.

It's a great deal!

There are also discounts for wholesale!

Buy five camps and get one free. A three-year training course is also available......

"How many orders are there estimated?"

"At least more than 10,000 sets. ”

"Really?"

"Really. ”

Chai Lufeng said solemnly.

He said that the market demand for this market is very strong.

And, basically, there are no competitors. Because others simply can't develop it.

Heavy artillery with a caliber of more than 155 mm was able to be manufactured by several large countries. However, the caliber ratio is more than 75 times, and only Tyrannosaurus Rex Industries.

What are the characteristics of shore defense artillery?

The requirements for mobility are not very high.

But the power must be great, and the range must be long.

In other words, these two characteristics are indispensable. Otherwise, others will not welcome it.

Who would be so stupid to buy useless things at a high price?

"I heard that the 203-mm howitzers, which were previously eliminated, were pulled out. But the range was too close. ”

"As far as shore defense artillery is concerned, 50 kilometers is too close. Without more than 80 km, there is almost no effect. ”

"If it's a missile, it's too expensive. Not cost-effective. The controls are also complicated. ”

"Besides, it turns out that the monsters of the deep can carry missiles. ”

The key is the barrel.

Barrels of more than 75 times the caliber.

Calculated according to the caliber of 155 mm, the barrel length will reach 11.625 meters.

This is a very powerful statistic.

In the case of 255 mm caliber, the barrel length will reach 19.125 meters.

Obviously, this data is even more perverted.

With such a slender barrel, it is not easy to ensure quality.

This is still 75 times the caliber.

If it's 100 times the caliber......

The 155-mm cannon with a barrel length of 15.5 meters will reach.

In the case of a 255-mm cannon, the barrel length will reach 25.5 meters.

Either way, it's terrifying.

Basically, such a barrel needs to be specially made.

At that time, the German King Tiger tank was equipped with a 71-caliber 88 mm tank gun. Sweep the battlefield invincible.

"As long as you can provide the barrels, we will be able to produce them immediately. ”

"So fast?"

"Of course. We all have ready-made solutions. ”

"Good. ”

Wang Buan was also polite.

Now is the time to go on a crazy spree.

The main thing is to make money from foreigners. This kind of money, naturally, the more the better.

Immediately ordered the Guanzhong Industrial Park to start production.

The first to be produced was a 155 mm, 75 times caliber barrel.

This is also the first coastal defense artillery system introduced to the market by Vulcan Heavy Industries. First of all, to test the reaction of the market, but also to test the quality of the barrel.

After the entire set of guns is produced, it also needs to be comprehensively tested for performance. It can take several months.

It must be to seize every minute of time and get to market as quickly as possible.

"How much does it cost?"

"I want 20% of the final selling price. ”

The sale price of a complete set of 155-mm guns is often calculated in millions of dollars.

Even if the price is $1 million per set, that's $200,000 a piece.

It only takes an hour to process a gun barrel. It is possible to process 24 pieces in one day. You can earn $4.8 million in pocket money in one day.

In fact, a 75-mm artillery system with a caliber of 155 times the caliber will definitely cost more than $1 million.

And the cost of the barrel is definitely more than 20% of the whole gun.

It's just that Wang Buan doesn't care too much.

He doesn't have the time to spend money at all, right?

used to be able to seduce a few flight attendant cuties, but now Pei Lan uses a helicopter to pick up and drop off every day, and she doesn't even have such benefits.

From this point of view, Pei Lan simply did it on purpose. Deliberately didn't give him a chance to spend his heart on the big radish.

Of course, in front of Pei Lan, he didn't dare to show any dissatisfaction.

In short, he still has some scruples about Pei Lan.

"How?"

"No problem. ”

Chai Lufeng did not bargain.

Of course, he hopes that the price can be lowered a little bit to increase the profit of Vulcan Heavy Industries.

However, the price offered by Wang Buan is already very sincere. If it is changed to Vulcan Heavy Industries, it may be offered 30% of the price.

After all, without a corresponding barrel, they simply have no chance of seizing the market.

From this point of view, it is completely reasonable for Wang Buan to seize the lion's share.

"Deal!"

"Deal!"

A memorandum of understanding was signed on the spot.

There is no prescribed quantity. There are no specified parameters.

The specifications and parameters of the barrel are provided by Vulcan Heavy Industries. Whatever the other party needs, Wang Buan will produce.

After the complete set of artillery was sold, the final settlement was made.

"Lao Chai, you say, what is the approximate price of such an artillery system for export?" Peng Deming asked curiously.

"I'm not telling you anything, at least more than $5 million. Chai Lufeng said in a deep voice.

"You already have an order?"

"There you go. ”

"How much?"

"More than 2,400 sets. ”

There was no reaction from the crowd.

Only Shangguan Yuqiang's eyes suddenly brightened.
