Global Cataclysm: Start building Noah's Ark

Chapter 87 Automatic Machine Gun Fortress!
In the defense circle design scheme, the main fire defense is the automatic machine gun fortress.

This thing is not an ordinary machine gun, but similar to the 11-tube anti-aircraft machine gun on Noah's Ark!
At the beginning of the design, Qin Bin considered copying the weapons similar to those on Noah's Ark and putting them on the base.

In this way, the base can have strong defensive firepower, and has a certain low-altitude air defense capability.

Thinking of this, Qin Bin immediately went to find worker No. 1, and asked him to reproduce the weapons on Noah's Ark, and then re-improved them to be suitable for use on land.

"Good master, I have stored all the data of Noah's Ark, which can be improved in real time!" said worker No. 1.

In a moment, an improved weapon appeared on the screen on his chest!

The naval gun has become a self-propelled artillery, which is a product of redesign with reference to the data related to self-propelled artillery published in the world.

But this thing is not an ordinary guy. From the above, there are more than 1300 parts of the self-propelled artillery!

The most important thing is that the extended barrel is a bit troublesome for the manufacturing center to manufacture, and it needs repeated heating and forging.

The number of such a big guy must be small, and the degree of difficulty is too high, unless a land-based manufacturing center is built and more manpower is available!

The self-propelled artillery must be built. This guy is a powerful weapon and a must-have weapon for the defense circle. However, if it is manufactured now, it will take up too much of the limited resources of the manufacturing center.

Now the manufacturing center is mainly used by Lao Bi in the physics laboratory to build semi-finished micro-nuclear reactors, and resources cannot be squeezed.

However, Qin Bin can make the self-propelled machine gun fortress first. This kind of weapon belongs to the category of firearms. All parts do not exceed 50, which is much easier to manufacture.

Qin Bin clicked on the chest screen of Worker No. 1 to view the design plan of the self-propelled machine gun fortress.

This design scheme also includes the outer shell of the fortress. It uses 130mm penetration-proof steel plate, and then includes a layer of insulation material. The chassis can be rotated 120 degrees, which can provide a machine gun shooting range of 120 degrees!

This machine gun uses the same firepower as Noah's Ark, with 11 tubes of 30mm caliber specifications, and the maximum firepower per minute is as high as 11000 rounds per minute!
And it has an independent system, which can intelligently lock the enemy and obtain specific data through the security circle monitoring system!
With the 5 tons of ammunition on the No. 4000 material ship, Qin Bin has no shortage of ammunition now, as long as the manufactured firearms can use these ammunition.

"Go to the manufacturing center and manufacture the automatic machine gun fortress!"

"I want to build 120 of these machine gun fortresses!" Qin Bin grinned.

Covering the entire defense circle, there are a total of 120 such machine gun fortresses. The terrifying firepower is extremely exciting to think about!
"Good master!" Worker No. 1 responded, turned and left the observation room.

……

three days later.

Zhuang Yan and He Chenguang boarded Noah's Ark.

As soon as I boarded the boat, I saw pieces of tarpaulins covering something.

There are also a large number of various arc-shaped steel materials piled aside, and the female soldiers of the Guards are still continuously transporting the arc-shaped steel materials with carts.

"What new instructions does the captain have?" He Chenguang looked at the things covered by the rainproof cloth and asked Zhuang Yan curiously.

"I don't know, I just told me to come over, and the captain will definitely arrange it later!" Zhuang Yan shook his head.

At this time, Qin Bin came out of the cabin and saw that both of them had arrived.

"You came just in time, there is one thing you need to do as soon as possible."

The two stood at attention and saluted, "Captain, please give me instructions!"

Qin Bin walked to the nearest piece of rainproof cloth and lifted the rainproof cloth, revealing an 11-barreled machine gun!
There was an icy breath from the black muzzle of the gun!
There are two large magazines under the base of the machine gun, which can hold a total of 600 rounds!
"Wait a minute, you use the crane to transport these self-propelled machine gun fortresses down, and then place them in the defensive circle according to my plan!" Qin Bin smiled.

The two looked at this self-propelled machine gun, and they were a little confused!

Isn't this similar to the anti-aircraft cannon on Noah's Ark? !
Look no further than decks with so much to offer!
very shocked
My dear, are there so many frames? !

Looking around, it is estimated that there are about 50 planes!

Qin Bin was dumbfounded when he saw the two of them, and said with a smile: "Okay, hurry up and take someone to install it. This is only a part, and it will be added in the future. The total number of such self-propelled machine guns is 120!"

"There are wires next to them. These machine guns are connected in parallel by grouping and summarizing. Pay attention. If it doesn't work, find two engineers."

Zhuang Yan quickly patted his chest and said: "The engineers brothers are busy with their work, so don't bother them! We can handle it, Captain, don't worry!"

"That's good, let's start working!" Qin Bin ordered.

"It's the captain!"

The two immediately informed the team members to bring the crane, then transport the self-propelled machine gun to the truck, and then install the fort shell.

They couldn't pull so many machine guns at one time, so the two organized a division of labor and cooperated to load the vehicles for three team members, two people drove for transportation, and the remaining five people were responsible for digging and assembling, installing self-propelled machine guns, and building up the machine gun fortress!

It only took one day, and the first batch of 50 machine gun fortresses was placed last!
He Chenguang and Zhuang Yan patted the snow on their bodies, and saw that the sky was getting darker.

"It's getting late, it's time to go back!" Zhuang Yan said with a sigh of relief.

He Chenguang was very satisfied with his masterpiece, and walked to the front of the machine gun fortress to look carefully.

The machine gun fortress is like a cylinder built on the flat ground, the white coating blends with the snow, and the black muzzle is hidden inside the fortress.

At present, this is a flat shooting state. If you want to shoot high, the cover above the fortress will be opened, and the gimbal below the machine gun will adjust the elevation angle, up to 85 degrees!
This machine gun fortress has low-altitude air defense capabilities!

With these self-propelled machine gun forts, the defense circle of the base can be said to be full of firepower!
This is only the first batch, and the total number is 120, which can completely cover the defense circle and form a dense three-dimensional cross-fire network. If there is a fight, I am afraid that even a fly will not be able to fly in!

The captain is really awesome!

He Chenguang sighed in his heart.

"Chenguang, let's go, it's getting dark!" Zhuang Yan got into the infantry vehicle and shouted at the door.

"Okay, here we come!" He Chenguang responded, and completely sealed off the machine gun fortress.

In the closed state, heavy snow can be isolated.

The two returned to the base in their infantry vehicles, and saw that the base was still bustling with activity.

This group of engineering soldiers worked overtime day and night, working 14 hours a day, and the construction machinery almost never stopped!
Lei Hui, the engineering platoon leader, was patrolling back and forth, his face was weathered and a bit tired.

"Old Lei, you have worked hard!" Zhuang Yan shouted to Lei Hui through the car window.

Lei Hui heard the voice, turned around and saw that it was Zhuang Yan, and said with a smile: "Work harder, persevere, and the work will be finished soon!"

It has been 10 days since the start of construction, and it was originally scheduled to be completed within 30 days.

However, Lei Hui never likes to finish things on the spot. He must finish the task before the time. This is his ability!

According to the current progress, it only takes about 30 days instead of 22 days, and the storage and living areas will be completed!
