When Xiao Feng got up the next day, it was already noon.

I called He Xiaojun and went to the cafeteria for breakfast. He Xiaojun had already gotten up.

However, he also knew that someone broke into Xiao Feng's dormitory at night last night, so he used this to joke with Xiao Feng for a while.

This guesthouse implements a buffet model. Although the food is not exquisite, it is very affordable.

The two of them each made some meals. As soon as they sat down, two big men sat down next to them with the meal.

"Hello, Mr. Xiao, we are from Department XXX. My surname is Li. This one is Officer Zhang..."

(Everyone understands that although I don’t want to write this paragraph, I feel that it’s a shortcoming if I don’t write it. Anyway, it’s all YY, but for some reasons, J-titles, positions, etc. are vaguely processed.)

Xiao Feng did not show much surprise when he saw the two big men sitting down.

Both the Air Force and the Navy have been recruited. Do you think you can pull down the army? Of course, no one can be left behind!

Two of my brothers and three have come. If the old mainland army members don’t come, then he will feel strange.

"Hello, Minister Li, Secretary Zhang..."

Xiao Feng greeted them with a smile, while Minister Li and Officer Zhang were enthusiastic people.

"Haha, we are old friends, our army is a big buyer of your Sunshine Hospital!"

"That is, before, my colleagues from the Northern Theater Command deal with you, but in fact, a lot of the supplies were allocated to the entire army from us."

The two of them narrowed the distance with Xiao Feng in just a few short words.

"Is that so? Oh my, I really have to thank you for taking care of our business!"

"Hey? Look at what you said. Actually, we should be thanking your company for developing so many good things, but it greatly improves the chances of our soldiers' survival on the battlefield."

Everyone exchanged a few greetings, but then Minister Li gave Director Zhang a wink.

Officer Zhang immediately said, "Oh, I don't think it's convenient to speak here, why don't we go there..."

Xiao Feng looked to the other side and happened to see the private room in the restaurant.

Although this is a military reception unit, how can there be no private rooms?

After all, sometimes after receiving some important leaders or very important meetings, even if you eat a working meal.

I will not eat in public anymore. After all, sometimes people have to communicate some important matters at the dining table, which is indeed not suitable for talking in public.

It was obvious that they were ready, but Xiao Feng was not polite, so he took He Xiaojun and a few experts into the private room.

When I went in, I found that the person had already prepared it, and it was filled with food and small white bottles.

And there are also a few other big guys who have a very unusual status at first glance.

Even Minister Li was very respectful in front of these big shots.

Later, Minister Li introduced the identities of those people to Xiao Feng, and Xiao Feng nodded and interspered with the big guys on the other side.

Everyone sat down. Minister Li, Officer Zhang and He Xiaojun were both good jokesters who were very good at creating atmosphere, and soon everyone became familiar with each other.

After drinking until three points, the boss sitting in the upper hand put down his glass and asked Xiao Feng with interest.

"Mr. Xiao, I think your industrial robots are very powerful. I don't know how accurate this processing..."

Xiao Feng had a meal in his heart and knew that the authentic dish was coming.

"As this, I really can't guarantee you all, after all, it's no point in saying it."

"Let's do this. If you have the chance, I might as well get a few machine tools and let's try it out as an interview."

"Hey! This one can be there. To be honest, we also saw the industrial robot of Xinghuo Technology that day. After drilling holes in the iron ingot, we suddenly had some ideas..."

Minister Li took over the conversation at this time. As an important cadre in a certain department of the Equipment Department, he took action personally this time, and his goal was actually very clear.

I just want to see if the technology of Spark Technology can bring a significant improvement in productivity to our military production.

"That's it! I also watched that video that day. To be honest, I was really scared!"

"I saw that robot drilling back and forth on such a large piece of square iron ingot, and finally drilling out a set of completed hydraulic valve boxes. To be honest, it really surprised me and opened my eyes!"

Officer Zhang immediately took it off and then the topic changed.

"Mr. Xiao, do you know what is the hardest for our army to produce?"

"Uh? This..."

Xiao Feng is a half-baked puppet army fan, and he really doesn't know much about the needs of the military.

Officer Zhang smiled slightly: "Actually, there are many headaches for our military, but there is one thing in it, such as cannons, which is one of the things that makes us headache the most..."

"cannon?"

Xiao Feng was stunned when he heard this, and at this time He Xiaojun laughed.

"Hey! I know this thing, isn't there a joke on the Internet, which is about our army being a patient with phobia for insufficient firepower, so the infantry squad has been equipped with a very powerful firepower coverage system..."

"Well, that's right, hey! This was all forced out of the hard days of those years!"

The big guys here also nodded with wry smiles.

It is true that decades ago, our predecessors were really too hard.

Why didn’t everyone want to go when they entered North Korea? It’s because the pressure brought to everyone by the United States is too great.

The firepower configuration of a battalion of Americans is even better than that of our division!

This is really no exaggeration. The number of artillery, caliber, and ammunition that a battalion can mobilize is more than that of a division.

As for the light and heavy machine guns equipped by a battalion, not to mention these.

Some people can even find air support and cooperate with tanks.

And what about us?

Only from the big brother did I get dozens of **sands...

So later, even in peacetime, we were crazily creating cannons of various calibers.

To make up for the psychological damage caused to us by the enemy's heavy firepower back then.

Even now, when people are paying attention to air suppression, we still invest a lot of enthusiasm and energy in cannons.

Because our army always firmly believes that artillery is the motto of war god!

Even now, there are missiles, various cluster bombs, and other high-tech weapons.

But in fact, when it comes to cost-effectiveness, it is still the best artillery.

But when it comes to artillery, we have to say that the problem of creating this barrel is.

It can be said that the military all over the world is facing such a problem now!

The basic life of a cannon is 6 seconds!

Many people may say after hearing this, aren’t you nonsense?

Such hard steel, do you actually say that its life span is only 6 seconds?

But this is the fact, not exaggeration.

The lifespan of a cannon is basically only 6 seconds.

Because the working environment of the artillery barrel is very harsh, if a shell is fired, the temperature inside the artillery barrel can reach up to 3,000 degrees, and the temperature outside the artillery barrel will instantly rise to more than 100 degrees.

If this continues, it will not take long, even the solid steel industry cannot support such losses.

Therefore, the lifespan of a gun barrel is basically 450 to 500 rounds, and it needs to be replaced.

The incident of a shell being fired is only a few seconds, so after counting, the lifespan of a barrel is only 6 seconds.

This is the average lifespan of artillery between Germany and the United States. When it comes to the rabbit, it is because of its crazy pursuit of firepower output.

Therefore, our gun barrel life can basically last two seconds longer than that of the United States and Germany, which means that it can last up to 8 seconds.

Some people may say, wow, then in this case, our metallurgical technology is very awesome...

Wrong! In fact, the reason why we have to be two seconds older than other parents is entirely because we are poor, poor, poor!

I will say something important three times. In fact, when the gun barrel is generally fired by about 400 large pieces, the barrel is actually almost worn.

Some of the barrels are even secretly damaged inside, so such artillery is actually very dangerous.

Therefore, when Germany and the United States usually fire 450 rounds, they will force the barrel to be replaced.

And because of our limited economic strength, we can't be as generous as them, so we can only find ways to metallurgy.

Although the life of the gun barrel is two seconds longer than others, to be honest, the power of the gun in the later period has been reduced.

For example, the degree of gunfire, rate of fire, range, etc. will be more likely to have problems.

Moreover, when the number of launches reaches a certain level, it will also be accompanied by this very high risk of explosion.

So in recent years, we are gradually thinking about moving closer to the United States and considering shortening the service time of gun barrels.

And this actually involves many aspects such as the production and manufacturing of gun barrels.

Speaking of the manufacturing of this gun barrel, it seems simple, but when it comes to the technical content inside, it is actually no less difficult than building a big guy like aeroengine.

It really takes more than ten years or even decades to develop a gun barrel steel, and continue to invest billions or even tens of billions of dollars to produce results.

Our artillery barrel steel technology has actually been far behind the United States and Germany, and even far inferior to the Mao Bear and Japan.

In this regard, it can be said that Germany has always been far ahead.

This situation has not been greatly improved until in the past decade, when we have continued to study science elites in China and serve our motherland.

And because in recent years, we have made great progress in smelting, especially in the field of desulfurization of molten steel.

Therefore, our gun barrel steel has achieved extraordinary leapfrog development. It is precisely because of this that our gun barrel has the confidence to last two seconds longer than the lifespan of the United States and Germany.

Of course, this kind of behavior is extremely risky, and the military does not recommend it very much now...
