"Suddenly! Dodo! "In a secret valley, a loud and coherent sound shook the birds of the forest.

A completely new, automatic large-caliber artillery gun is undergoing intense experiments. This rapid-fire gun of 30 mm caliber, this anti-aircraft gun has a very simple structure and is a very practical "anti-aircraft weapon".

In fact, this artillery also bears the heavy responsibility of ground defense for the future Elanhill troops. Chris's idea was to meet both the needs of the troops in air defense and on the ground with one weapon.

The choice of caliber for the new weapon system was discussed in detail, and Chris even brought Modlaire back for a meeting.

Initially, Wagron felt the idea of using a modified version of the 75 mm infantry field gun for ground combat, while developing a new anti-aircraft gun to defend against targets that might appear in the sky.

However, this plan was later rejected, because it would not only waste the production capacity of 75 mm caliber infantry guns, but also cause more logistical problems. To put it simply, this is equivalent to the production of three shells of different natures, and the supply aspect will become more complicated.

The subsequent proposal was proposed by Chris, who felt that the use of 88 mm caliber cannons would solve the problem of both air and ground. However, Desel felt that the rate of fire of this large-caliber gun was too slow for attacking the agile dragon, so he was forced to give up.

Chris also felt that before the development of radio proximity fuses, the effectiveness of large-caliber anti-aircraft artillery was too low - and the range advantage of large-caliber anti-aircraft artillery could not be reflected on the battlefield, which made the very useful 88-millimeter caliber cannon useless.

After all, an 88 mm caliber cannon with an altitude of 10,000 meters is too wasteful to deal with a dragon with a flight altitude of only a few thousand meters. Medium-caliber or small-caliber anti-aircraft guns seem to be more suitable.

So, another serious question came to paper: what if a small caliber was used, then it was not powerful enough? After all, facing a dragon with scaly armor, and using weapons such as large-caliber machine guns to defend his body, Chris has a feeling of insecurity anyway.

So, soon, the 12.7 mm caliber heavy machine gun air defense scheme was overthrown, and Deser also believed that relying on such anti-aircraft weapons could not block both the Warcraft cavalry on the ground and the dragon in the sky.

Then the choice of weapons began to focus on small and medium-caliber anti-aircraft guns. There are many options proposed by Chris, and everyone has their own optimistic plans.

For example, General Wilkes, who emphasized the mobility of the troops, and General Modryer, supported 20 mm anti-aircraft guns, because they were the lightest, could easily maneuver with the troops, and were easy to deploy.

However, this caliber also has some shortcomings, that is, Chris and Desel have been worried about the problem of not being able to pose a killing threat to the dragon.

On the other hand, Wagron, Kolya and others supported the use of 40mm Bofors anti-aircraft guns, which they believed were very damaging and had a slow rate of fire, and could be used as a multi-purpose weapon to equip troops.

However, the Bofors anti-aircraft gun also had its own shortcomings, that is, the maneuverability was really not very good. As a rule, such weapons are towed forward by a tractor and cannot be immediately put into battle.

In addition, most of the barrels of the Bofors anti-aircraft guns are water-cooled, so as to maintain continuous combat capability - the navy does not care, anyway, it is not a little bit of weight, but the army side is really unbearable, so it can only endure the pain.

Therefore, after some careful selection, the caliber of 30 mm has become a choice that everyone can bear. On the one hand, this caliber can be used as a reference, and on the other hand, the rate of fire and weight are good, which can meet the needs of operations.

After the weapons were chosen, the arsenal worked overtime to start trial production. It's still a familiar taste, it's still a familiar recipe: Chris took the lead, leading a group of craftsmen to make such a test model of high-level dual-purpose weapon in front of him by hand.

This is a very interesting weapon: it uses a magazine feeding system that can reach a theoretical rate of fire of more than 200 rounds per minute. It was also equipped with a steel shield and was used as a flat-firing battery.

The entire 30 mm rapid-fire gun was mounted on a carriage with eight small-diameter wheels to achieve a stable firing environment and effectively reduce the altitude. The eight wheels of the carriage are attached to the sides with iron to increase the load-bearing and supporting strength.

If necessary, the rapid-fire gun itself can be removed from the wagon and reinforced to the ground as a fire support point, or it can be directly produced and deployed in castles and important locations as defensive batteries.

All in all, this is a very versatile weapon, and Chris knows that once this weapon starts mass production, he will have to make do with it for 3 years or more. It is a pity that this kind of advanced rapid-fire gun has no way to be equipped with rubber tires.

"There's not enough elastomer......" Looking at the somewhat hair-making old solid wood wheels, Chris felt his aesthetic crumble. A World War II-era 30mm rapid-fire gun, plus a medieval carriage, is really an indescribable sour match.

No way, his principality now only has the territory of the north, and it can't grow any rubber at all: even if he wants to import a large amount of natural rubber, the Arrant Empire, which already has a tense relationship with Irlanhill, will not be willing to meet Alleyland's import needs anymore.

Thinking that he would have to be dragged down by something like rubber for a long time, Chris's mood couldn't get any better. Although what he has in front of him is probably the most powerful war machine of this era......

"If it really doesn't work, let's start with the Higgs Kingdom...... Let them help us buy rubber from the Dosen Empire, and I guess Arrant won't interfere, right? General Bourchos suggested.

"We're already doing that." Chris smiled bitterly, shook his head and said, "But there isn't much natural rubber...... The price is ridiculously high. Now the surrounding countries are about to reach a tacit agreement, and the price of what we want to buy will skyrocket. ”

"It's better to go up the price...... The key is to hold the gold coins, you can't buy them......" Deser shrugged his shoulders and said helplessly: "The things we need are getting more and more complicated, and there are more and more businesses, and there are fewer and fewer merchants who can supply us." ”

With a sigh of regret, Modryel exclaimed: "This weapon is really good, if two cannons are put together, the rate of fire can be doubled!" ”

"Don't think about the duplex." Looking at the experimental artillery that was firing, Chris said to several generals around him: "Although I also want to increase the density of firepower, the load of the carriage and the recoil are all things that have to be considered......"

"Capacity is also an issue! We can't produce so many 30mm anti-aircraft guns for a while......" Smith also shook his head and explained: "So, the design is a single gun and one vehicle. ”

For the factory, there is actually no production pressure on the carriage without any difficulty, and it is the number of anti-aircraft guns that determines the number of anti-aircraft guns themselves.

"Moreover, when this thing was designed, it was designed with battle damage in mind......" Glancing at Wagron and other generals, Chris said helplessly: "This weapon may become a weapon for dragon slaying, and naturally it will be attacked by dragon knights...... Dragon's Breath is no joke. ”

"Once attacked by a dragon, these anti-aircraft guns and anti-aircraft gun shooters will be lost. Therefore, only by decentralizing and deploying can we achieve the greatest results. Chris said, with a look of some unbearability.

These anti-aircraft gunners, each and every one of them in the future will take risks to fight. They will become the first target of the dragon's attack, and may sacrifice their lives at any time. Only after they are all eliminated will those infantry lose their barriers, and only after all these anti-aircraft guns are muted can the dragon knights get a more ideal attack environment.

"Besides, there aren't enough shells! We are under a lot of pressure to produce bullets, and the arsenal has begun to expand, expanding four in one go, all of which are for the production of ammunition. Smith had a toothache when he mentioned this.

Modern warfare is really real money. Those shells and bullets are massively produced, and a battle is exhausted, and the average poor person really can't afford to play. Seeing the advent of automatic weapons, Smith knew that ammunition consumption in the future could be even higher.

What he could not have imagined was that in another world, the American army in the twenty-first century, it would take 250,000 bullets to destroy an enemy...... What is this concept? The concept is that a 10,000-ton freighter loaded with bullets can only provide enough ammunition to kill 800 enemies......

Of course, Iran Hill is far from extravagant to that extent. They were not even able to equip some anti-aircraft guns. However, it was precisely this anti-aircraft gun in front of him, which was firing and experimenting with various performances, that for the first time provided a possibility for mortals, a possibility to face the dragon head-on.

"It's true, if you use a double, the ammunition consumption will be doubled, and we don't have that much ammunition." General Waglon, who was well aware of the lack of ammunition, nodded in agreement with Smith.

However, Jean immediately spoke again: "However, Minister Smith...... You really need to increase your production capacity, but we're building more troops now......"

"Don't worry! By this time next year, our arsenal will be at least ten times the size of what it is now! Secretary Smith of the Department of Industry replied confidently.
