Let you repair fishing boats, what the hell is 52 destroyers?

After the shock, Lu Xuan returned to his laboratory.

Export the magic modification plan from the system and name it Type 55 destroyer.

Transforming a fishing boat into a warship was a serious crime, and Lu Xuan didn't want to go in and use a sewing machine.

It is hoped that this technical information on the Type 55 destroyer can offset his charge of privately building warships.

Computer hard drives in this era were still very small, so Lu Xuan could only export the data and copy it to a CD.

The R&D data for a 10,000-ton large drive is quite large. Exporting the data and storing it on a CD is a huge workload.

Lu Xuan worked all night to finish it without even closing his eyes.

Unknowingly, it was already dawn, and Lu Xuan was about to take a nap.

There was a knock on the door and the panicked voice of the assistant.

"Boss, no good, a big shot wants to see you..."

"It's just a small warship, but it still alarms the big shots?"

Lu Xuan curled his lips, packed up and walked out of the laboratory.

Under the"escort" of two armed soldiers, Lu Xuan came to a studio.

This studio was originally where Lu Xuan convened maintenance masters for a meeting to discuss The place.

It has now become a temporary office of the military, and there are soldiers on guard outside.

Lu Xuan walked into the studio and saw a majestic old man carrying a general.

Before Lu Xuan could speak, the old man waved. , motioning Lu Xuan to sit down.

Then asked:"Are you the boss of this fishing boat repair shop?

Lu Xuan replied:"Yes, my name is Lu Xuan."

The old man said:"I am the Commander-in-Chief of the Navy, Qi Minghai.""

Lu Xuan suddenly gasped. The big shot was actually the Commander-in-Chief of the Navy!

Qi Minghai stopped talking after introducing himself and flipped through a stack of documents in his hand.

This stack of documents was about the details of Lu Xuan and the eighteenth generation of Lu Xuan's ancestors. Information.

The Navy Commander-in-Chief did not speak, and Lu Xuan could not speak, so he could only sit quietly.

I don’t know how long it took, Qi Minghai stood up and walked out and said:

"Come with me to your renovated fishing boat."

Lu Xuan almost fell asleep. He stood up immediately after hearing this.

When Lu Xuan followed Qi Minghai to the Wave Breaker, he saw a group of people wearing scientific research uniforms busy with something.

Among them were young people and middle-aged people. , there were also gray-haired old men.

The leader was an old man about 60 years old, wearing a pair of black-rimmed glasses.

He was leading someone with an instrument to test the twin 130mm cannon.

Looking at the instrument Value, his expression can no longer be calm.

"This strength value is simply incredible!"

"Can anyone tell me what gun steel technology this is?"

Seeing the old man's strange appearance, Lu Xuan couldn't help but said:

"This is ordinary gun steel, just with rare earth elements added."

Hearing Lu Xuan's voice, the old man looked back with surprise on his face.

Lu Xuan then explained:"At present, most cannons are made of tungsten alloy steel."

"Although tungsten alloy steel has high hardness and good high temperature resistance, the gun barrel produced has low toughness."

"After the gun barrel is fired multiple times, it will reach the metal fatigue strength due to the high temperature and high pressure generated when the gun is ejected from the chamber."

"The barrel must be replaced when it reaches the end of its service life, otherwise the hit rate will decrease, or even an explosion accident may occur."

"Our country's gun barrel can fire more than 300 rounds, Mao Xiong's gun barrel can fire about 500 rounds, and Yingjiang's gun barrel can fire about 600 rounds."

"The barrel made of gun steel with rare earth elements added can fire at least 1,000 rounds."

Hearing Lu Xuan's words, the old man frowned:"Rare earth elements, are they really that important? Lu Xuan chuckled:"

This twin 130mm gun is made of new gun steel and can fire 1,200 rounds.""

Lu Xuan just wants to use facts to prove the importance of rare earth elements and attract the attention of the country's top officials to rare earth resources.

Rare earths are not only important for the military industry, but also indispensable in aerospace, satellite guidance, electronics industry, etc.

But now , the country did not realize at all that for the sake of foreign exchange, it exported large quantities of eagle sauce, foot pot chicken and other countries at cabbage prices.

By the time the country discovered the huge role of rare earths in the 21st century, almost all of the domestic rare earth resources had been sold

"Can this gun fire 1,200 rounds?"

The old man's face was full of shock and disbelief.

That is nearly 4 times the service life of domestic gun steel.

The service life of gun steel produced by Mao Xiong and Yingjiang is more than 2 times.

If this is true, how many resources will be saved for the country?.

It can also greatly extend the service life of equipment and enhance the combat effectiveness of the army.

At this moment, not only was the old man frightened, but even Qi Minghai couldn't help but be moved by it.

"Can you call 1200? You can test it now"

"Moreover, didn’t you conduct material testing?"

Lu Xuan was speechless. He explained it so clearly, why didn't he believe it?

Qi Minghai waved directly, called Deng Jianjun over, and ordered:

"Live ammunition test the actual service life of this gun"

"Yes, Chief."

Deng Jianjun immediately ordered someone to control the cannon.

It fired wildly at the sea in the distance. Boom boom boom. Two cannons were fired every three seconds.

This efficiency shocked everyone. However, with the test, Continuing, everyone was frightened. 100 rounds, 300 rounds, 500 rounds, 800 rounds, 1100 rounds

...

By the time 1,200 rounds were fired, the barrel was already dark red.

Deng Jianjun had to order the soldiers to stop the shelling.
