I built an armada

Using the YJ-901 anti-ship missile to test the air defense capabilities of the 1130 close-in defense gun, and on a warship, Su Dingping couldn't help but be a little excited.

Even in later generations, there was no such luxury test. After all, if you are not careful, the warship will be finished.

In addition to not being able to use warships for actual testing, the 30mm caliber fin-stabilized discarding sabot armor-piercing projectiles for close-in defense artillery are also very expensive.

Even in the military industry system of later generations, the cost can be controlled very low. A tail-stabilized discarding sabot armor-piercing bullet costs 2,000 yuan!

One minute costs 22 million yuan! One second costs 370,000 yuan!

Therefore, there is a famous saying in later generations: How many seconds is enough for your annual salary to be close to a cannon?

Although the 1130 close-in defense gun can fire 11,000 rounds per minute and at least 160 rounds per second due to different types of ammunition, it can only be equipped with a maximum of 2,500 rounds due to the bulge ammunition supply method.

In other words, it can intercept for 15 seconds at a time, and it takes up to 5 minutes to reload ammunition.

But 15 seconds is enough. After all, the maximum interception distance of the 1130 close-in defense gun is 5 kilometers!

The speed of the 'SS-N-22 Sunzhi' supersonic anti-ship missile is Mach 1.3, and it takes 11 seconds to cover 5 kilometers. The YJ-901 anti-ship missile has a speed of Mach 1.6 and takes 9.2 seconds to cover 5 kilometers.

As the speed of anti-ship missiles increases, the time required to break through the distance of 5 kilometers becomes shorter and shorter.

Therefore, there is not much time left for close-in defense artillery, only about 10 seconds. To intercept anti-ship missiles that break through the air defense fire network and approach warships, 15 seconds of ammunition stock is enough.

As for the slower anti-ship missiles, they cannot even break through the interception fire network of anti-aircraft missiles and anti-aircraft artillery, and there is no need for close-in defense artillery.

On the sea, 30 kilometers away from the shipyard, 052D is floating on the sea. Standing in the 052D main control room, Su Dingping silently counted the time in his heart.

At a distance of 5 kilometers, it takes five seconds for the tail-stabilized armor-piercing projectile to have an initial speed of 1 kilometer per second. Coupled with the speed of the YJ-901 anti-ship missile of Mach 1.6, the first round of contact is expected to be 3.2 seconds later and 3.2 kilometers away from the warship.

How many YJ-901 anti-ship missiles can be intercepted depends on the next 6 seconds! After these 9.2 seconds, if there is still a fish that has slipped through the net, it can do nothing because the missile has already hit the warship.

As time passed by second by second, suddenly, the close-range anti-gun radar in the main control beeped and alarmed.

Obviously, the distance between YJ-901 and the warship is only 5 kilometers.

No secondary operation is required. The 1130 close-range artillery fire control radar automatically locks 4 targets.

The next second, a deafening clicking sound echoed in my ears.

The dazzling 'spark ribbons' danced wildly in the air, and together with the sharp whistling sound of the missiles, they composed a strange symphony.

"1 second!"

"2 seconds!"

"3 seconds!"

Su Dingping muttered silently.

"4 seconds!"

Suddenly, there was a loud "bang" sound, and the first YJ-901 anti-ship missile was successfully sniped and exploded in the air!

At this time, the missile is still 2824 meters away from the warship! There are still 5.2 seconds to survive!

"5 seconds!"

Bang bang——

There were two violent explosions in succession, and the space in the distance was filled with smoke.

At this time, the missile is still 2,280 meters away from the warship! There are still 4.2 seconds to survive! And one last anti-ship missile.

"6 seconds!"

Bang——

The fourth YJ-901 was successfully intercepted, 1,736 meters away from the warship!

The first round of testing was just four YJ-901 anti-ship missiles, and the 1130 close-in defense gun successfully intercepted them!

"It seems that the 1130 close-in defense gun recorded in the previous life has good interception efficiency against anti-ship missiles below Mach 3. It is true."

At least four Mach 1.6 YJ-901 anti-ship missiles cannot break through the defense.

Looking at the bullet casings on the ground, Su Dingping waved his hand, and everything returned to its original state.

The next second, he appeared on the shore.

After adjusting the YJ-901 anti-ship missile, he appeared in the main control room again.

This time, a salvo of eight anti-ship missiles was tested to see how many were intercepted.

After a while, with the sound of explosions coming one after another in the air, all eight anti-ship missiles were intercepted.

He came to the deck, took out a pen and paper and wrote down a series of numbers.

8 seconds! 8 YJ-901 anti-ship missiles!

The final survival distance is only over 600 meters, and the survival time is 1.2 seconds.

At this distance, the shock wave generated by the explosion could hit the deck.

Immediately, he tested a salvo of 12 anti-ship missiles.

After a while, Su Dingping, who was standing in the main control room, heard a huge explosion.

As the warship shook violently, two missiles exploded on the deck.

With a thought, everything returned to its original state.

"In 9.2 seconds, 10 Mach 1.6 YJ-901 anti-ship missiles were intercepted, and two more broke through the close-in artillery and air defense fire network and hit the warship."

This data is already quite good.

You must know that being able to allow 12 anti-ship missiles to break through the anti-aircraft fire interception network formed by anti-aircraft missiles and anti-aircraft artillery and reach 5 kilometers close to the warship means that this is a battle with great disparity in strength.

It takes at least 25 anti-ship missile salvos to achieve this result! Or, the anti-ship missile is too fast, and this situation is not suitable for testing for the time being.

After walking around the 1130 close-range anti-gun equipment, Su Dingping shook his head and sighed.

"No, there is still a gap between this data and the data given in the previous life, and we need to continue to adjust!"

"If we can intercept all 12 YJ-901s, that should be enough."

With a wave of his hand, the newly installed 1130 close-range anti-cannon components instantly separated into thousands of parts. Immediately afterwards, the original 1130 close-in defense gun on the 052D was also disassembled into parts.

Time flies by.

Early the next morning, when Su Dingping walked out of the military industrial illustration forging space, he couldn't help but stretch.

After a night of adjustment, testing, optimization, and re-adjustment, the current 1130 close-in defense gun can finally intercept 12 Mach 1.6 YJ-901 anti-ship missiles at once.

12 is the limit, and 16 salvos are impossible to resist.

Su Dingping was already very satisfied with this result.

If a fleet battle at sea can allow more than 12 anti-ship missiles to break through the heavy air defense firepower network and advance to the point where the 1130 close-in defense artillery is needed, the naval battle has been lost.

There is no need to fight this kind of battle.

As the last guarantee for warships, close-in defense guns are used for emergencies, not for cover-ups.

Dong Dong——

Following a knock on the door, Zhang Gongnong couldn't help but be surprised when he saw Su Dingping with a good face opening the door.

"Dingping, judging from your face, you won't have a new breakthrough, right?"

Su Dingping smiled and asked instead of dwelling on the topic.

"What's wrong, Professor Zhang?"

"I'm going back to school today! It just so happens that the dean gave me a task to take you on a vacation! Let's go together."

"Okay! Then I'll clean it up."

This time, Su Dingping didn't object.

For scientific researchers, the so-called vacation is nothing more than changing places to continue scientific research. Everyone knows this.

Just like Zhang Gongnong, although he goes back to school to be busy with the graduation of his students, once he has free time, he will definitely continue to study the 052B core technology.

Su Dingping also knew that staying here would bring great psychological pressure to Sun Yongguo and others. Give yourself a holiday and treat them as a holiday.

Moreover, currently staying at the military base, apart from occasionally helping Sun Yongguo and others answer questions on 052B, there is nothing else. Most of the things he can do in the forging space of the Military Industrial Illustration.

Seeing that Su Dingping was so cheerful, Zhang Gongnong's words that he had been planning for a long time were all in vain.

"Hey, if I had known that Dingping was so cooperative, I wouldn't have hesitated at the door for so long just now."

Half an hour later, the military base airport.

Sun Yongguo and others were bidding farewell to Su Dingping at the airport.

"Dean, I'll be back tomorrow."

Lu Guangjun waved his hands quickly.

"No, no, no! No, no, what can you do in one day? Traveling back and forth all on the plane, how tiring it is. Dingping, go back and play for a few more days this time, don't be in a hurry to come back!"

"Yeah, don't worry! We are here, there will be no problem." Sun Yongguo also said.

Seeing everyone's nervous expressions, Su Dingping immediately smiled.

"Dean, don't worry, I will come back when the chief gives me news. By then, we will go to the next battlefield."

"That's good, that's good."

Sun Yongguo and others suddenly breathed a sigh of relief.

Although he didn't know what Su Dingping and the chief were planning, he knew that this matter would definitely not be easy to handle.

It takes a few weeks to say less.

After waving to everyone, Su Dingping and Zhang Gongnong entered the airport.

The plane took off quickly and disappeared from everyone's sight soon.

"After leaving Dingping, I feel much more relaxed." Lu Guangjun suddenly laughed.

"Don't be too proud. Dingping will be back in a few days. If we don't study the 052B core technology thoroughly enough, we may not be able to keep up with his subsequent research."

Not only was Sun Yongguo not too happy, his expression was rather solemn.

"Indeed! Although Dingping has gone back, we still can't relax." After sighing, Lu Guangjun changed the topic and said: "By the way, Lao Sun, just now Dingping said that we will rush to the next battlefield when he comes back. What does this mean? ?”

"Well……"

After frowning and thinking for a while, Sun Yongguo said: "Maybe it's an improvement of 052B! Didn't we see those design drawings in his room last time."

Lu Guangjun suddenly understood.

"Stop talking, hurry up and do it quickly."

A few hours later, the two arrived in Harbin.

As soon as the two arrived, the manpower that had been prepared secretly was quietly spread out.

An hour later, the two of them arrived at the school one after the other.

At the same time they entered the school, the team led by Wan Long successfully lurked into several secret strongholds predetermined around the school to serve as a backup force to protect Su Dingping's safety.

Not only that, there are also secret agents who came from other cities under Xu Dongguo's orders and sneaked into the school quietly in various identities to serve as the most direct protective force.

These actions did not attract the attention of anyone in the school. Even the principal, who held a high position, was kept in the dark at this moment and did not know that the entire school was under close surveillance.

At the end of March, the campus was filled with feelings of separation and separation. There is an extra hint of sadness in the soft spring breeze.

Many people walked in a hurry and seemed to have something on their minds.

Many senior and third-year graduate students who do not plan to continue their studies are already busy looking for jobs.

Undergraduate and graduate students in 2000 were still very popular, and it was a prestigious school, so I could be picky about jobs.

Some couples who are not in the same class or are going to different cities are inseparable on the way to campus.

Looking at this scene, Su Dingping's mood fluctuated slightly.

As a senior, he is about to graduate.

If he hadn't awakened the system, he would have received the notice of studying for a master's degree and a Ph.D. by now. The greater possibility is to directly enter the list of direct blogs.

From being three years apart from Zhao Haikuo, they became the same year's first degree students. There is a six-year age difference between the two, but they are in the same class. It is estimated that the psychological pressure of the same PhD students will not be less in the next four years.

Just as Su Dingping was strolling, suddenly, a voice came from behind him.

"Junior Brother Su? It's really you! Long time no see!"

Su Dingping turned his head and glanced, and suddenly felt that the other person looked familiar.

Upon closer inspection, he realized what he was doing.

The other person was Chen Kai, whom he had met in the dining hall a few months ago. He had discussed with himself that he did not plan to stay in school and get a doctorate, and he planned to apply to a prestigious school in the beautiful country.

Su Dingping didn't even expect that he would be the first person he met when he returned to school.
