Back in 1978, I was admitted to Northwestern Polytechnical University.

Chapter 363: They even have bunker buster bombs! Northwestern Polytechnical University has everything it needs!
Target site.

A large crowd gathered around, and Old Lin pushed his way through the crowd while complaining.

"Old Liu, you're such a blockhead! You still don't trust Northwestern Polytechnical University's technology even after I've driven you ten miles away?"

Old Lin complained that when he wanted to get closer to observe the experiment, a large group of people were unwilling, saying they were afraid the bomb might miss its target. Even if there was no explosive or fuse inside, there was still a great risk if half a ton of something fell.

As a result, the bomb fell, and people nearby gathered to watch, so I had to take a car to get there!
"Everyone, make way!"

With a whoosh, the crowd dispersed, and Old Lin walked to the ventilation opening. There used to be an umbrella-shaped cover over it, since there was a lot of rain in the monkey area, and without a cover, water would easily seep in.

I was initially worried that this thing would deflect the bomb, but how could it be deflected when it hit at high speed? It smashed the thing to pieces, leaving not even a few fragments. The bomb continued to fall and crashed into the ventilation shaft. There were scratches on the edges, but they weren't serious, which means it was at most half a meter off the center.

Accuracy of half a meter!

Below the ventilation shaft, the bottom was unfathomable. The bomb went down and then entered the concrete fortification next to it. After looking at this side, Old Lin went into the fortification and looked at the bomb, which had been horribly damaged by the collision. Its wings were gone and its tail was crooked. His mouth was crooked with a smile.

"Good, good, good! We were worried about this before, but now, one bomb has solved the problem. Sixty kilometers away, that accuracy... Northwestern Polytechnical University's technology is the best in the world!"

"Mr. Lin, you flatter me. I was just thinking that we might be able to improve the bomb so that even without ventilation openings, it can still destroy this reinforced concrete fortification!"

"Really? How can we improve it?"

"Does our unit have any decommissioned 152mm howitzer barrels?"

“We have a few at our Northwest firing range, so we can modify them and give it a try!” Liu Zhiqiang quickly said. He had to fully support Northwestern Polytechnical University’s suggestion!

Northwest firing range, inside the weapons depot.

Countless people stared wide-eyed as Qin Liang carried out his modification work.

The Type 66 152mm howitzer was copied from the Soviet D-20 152mm howitzer and was heavily equipped by the troops. Even now, in the south, this cannon is still teaching the Vietnamese a lesson, making the Vietnamese artillerymen suffer and they dare not fire at it.

The more than four-meter-long cannon barrel was disassembled. Qin Liang welded a pointed tip to the front of the barrel. The inside of the barrel was filled with explosives. At the back of the barrel, four single wings were welded on and a satellite guidance system was installed.

It's about modifying bombs, but actually it's about using bomb parts to modify cannon barrels!

"President Qin, do you intend to mount this cannon barrel on an airplane and use it as a bomb?" Liu Zhiqiang asked cautiously.

"Nonsense, can't you tell? This cannon barrel is a bomb!" Old Lin rolled his eyes at him, as if complaining that he was ignorant. In reality, Old Lin was also in a state of extreme shock.

Who would have thought of such a creative idea?

The army's armor-piercing projectiles are essentially long and thin rods, which allow for optimal penetration depth. Just like when the army is attacking tanks, they need to use long and thin rods to penetrate reinforced concrete fortifications on the ground!

It would be too wasteful to manufacture a special penetrator like this. Using a scrapped gun barrel is a perfect fit! With the help of a satellite navigation system, this thing can accurately land over the target, dive down, and penetrate at a 90-degree angle. Even a 10-meter reinforced concrete fortification will turn into a pile of tofu!
I bet only Liangzi in the whole world could come up with this idea!
Actually, this is giving Qin Liang too much credit.

How to destroy the enemy's strongholds is a difficult problem faced by all military experts. During World War II, in order to destroy Germany's strong submarine bunkers, the British developed a ten-ton high-barrel bomb that could penetrate forty meters of reinforced concrete.

During the Vietnam War, the Americans developed the BLU-82 giant incendiary air bomb, which could generate a powerful shock wave to attack tunnels and caves, and could also burn up the oxygen inside.

However, these were not professional bunker buster bombs. In the 1980s, when the Davids bombed the nuclear reactor at Eto, they used only the most ordinary 908 kg bombs, successfully destroying the target through multiple explosions.

It wasn't until 91 that the US military decided to attack Iraq, and it was necessary to destroy strong military targets such as air defense command centers, which were protected by thick reinforced concrete.

So they urgently developed the GBU-27 Paveway III laser-guided bunker buster, but it could only penetrate one or two meters of reinforced concrete, which was still not enough. So, American military experts had a brilliant idea: they took the scrapped 203mm gun barrels, filled them with explosives, and installed guidance devices, thus creating a powerful bunker buster!

This bunker buster, codenamed GBU-28, successfully penetrated Saddam Hussein's underground air defense facilities on its first use, not only eliminating the target but also killing more than 5,000 civilians, making it famous overnight.

We in the East don't have cannons with such large barrels, but we have 152mm ones, which are not inferior. The key is that the aircraft carrying these cannon-barreled bombs can be twin-engine Q-6 variable-sweep wing fighters, which can accelerate to Mach 2. At that speed, the destructive power of our cannons is also quite strong!

A ten-meter-thick reinforced concrete fortification, definitely!
Of course, there are still risks involved in launching something like this with twin Q-6 missiles at supersonic speeds. The computers at Northwestern Polytechnical University need to perform some calculations, and the control laws of the cannon barrel and the bomb itself also need to be calculated...

After finishing his work, Qin Liang stood up.

"Done? Someone, get him on the plane!"

"No rush!" Qin Liang said, "We still need to send the data back so that Northwestern Polytechnical University can do the calculations. Let's use our communication satellite."

"Communication satellites? I don't think we...have any, right?"

"Of course there is," Qin Liang said. "The BeiDou navigation system can transmit information. Although the amount transmitted each time is not large, it's enough, Professor Zhu!"

Zhu Qiu nodded, walked to a vehicle-mounted device outside, got on, and started typing furiously on the keyboard.

"Let's go, Mr. Lin, let's get something to eat. I'm hungry. Oh, and I'm not drinking anymore..."

"If we're not drinking alcohol, let's just have some wheat juice to soothe our throats. Today's experiment has given our Air Force complete confidence; we should celebrate..."

the next day.

The more than four-meter-long gun barrel was hung under the belly of the twin-engine Q-6 bomber. Compared with ordinary aerial bombs, it appeared more slender and unique.

Dropping a cannon barrel from 10,000 meters in the air was a first for everyone, and their eyes were filled with curiosity.

"Report, flight preparations are complete, requesting takeoff!"

"Ready for takeoff!"

With a roar, the twin-engine Q6 took off again. Old Lin walked to the 212 beside him and said, "Drive, stop 300 meters from the target fortification."

"No, no, Elder Lin..."

"This is an order!"

"I'll go too, I'll stand with Old Lin." Qin Liang also got into the car.

Yesterday, Old Lin kept complaining because the viewing distance was too far. Today, no matter what, he needs to observe it up close. As for whether the bomb, which has been simulated on the computer, can actually fly according to the program, Qin Liang is not 100% sure.

So, I'll stand with Mr. Lin. There's a risk involved, but we'll all be on the same page.

Seeing that he couldn't persuade Old Lin this time, Liu Zhiqiang could only get into the car and say, "Okay, I'll stand next to you too."

Yesterday's simulated attack failed to destroy the building, but today is different. When the cannon comes down, it will surely collapse the building. Therefore, the explosives and time-delay fuses inside the cannon are all real.

If this building can be completely destroyed today, that would be great. If not... that's okay too. Yesterday's experiment has already satisfied the troops.

A roar echoed in the sky. The Twin-Type 6 fighter jets circled in the air, waiting for Elder Lin to see the effect. Cough cough, this was a simulated attack, a simulated attack once.

After flying overhead, on the second lap, the twin-engine Q-6 began to accelerate rapidly, Mach 1, Mach 2... When it reached Mach 2.3, it dove and dropped its bombs!
Last time it was a gliding munition that could fly dozens of kilometers, but this time it dropped the cannon barrel, and the distance of the bomb drop was less than ten kilometers.

In the sky, a thick, long cannon barrel flew down at Mach 2.3. Under the influence of gravity, its speed continued to increase, Mach 3, Mach 4...

Everyone felt a sharp pain in their eardrums, but Qin Liang felt relieved.

This is definitely a hypersonic weapon! If it weren't for the fear of provoking the monkeys and not planning to use ballistic missiles, there would be no need for fighter jets to drop bombs; a ballistic missile could just fly over directly! Even a short-range Scud missile has a landing speed exceeding Mach 5!

Hmm, it seems there are still many research directions to explore in the future.

Boom!
The cannon barrel finally slammed into the ground. In that instant, dust billowed up, and Old Lin grinned. Accurate hit! Accurate hit again! This precision-guided weapon developed by Northwestern Polytechnical University has never let me down!
A huge tremor came from beneath my feet, and it continued, making me feel unsteady, as if I had just experienced an earthquake.
Everyone stared wide-eyed ahead, but in reality, they couldn't see anything at all, because countless fragments of reinforced concrete were already flying everywhere. Even a mile away wasn't necessarily safe. Seeing the concrete chunks flying towards them, several soldiers immediately stepped forward, using their bodies to shield Elder Lin and the others. Thick, long steel pipes continued to drill in, shattering concrete and snapping steel bars wherever they went.

Three meters, five meters, eight meters...

Finally, its front end loosened, and it had drilled through the thick layer of reinforced concrete!

At this moment, the internal time-delay fuse finally came to a head.

boom!
Amidst the violent explosion, more cement blocks were blown into the air.

"Quickly, protect Elder Lin!"

Before Liu Zhiqiang could finish speaking, Old Lin was tackled to the ground.

Old Lin was somewhat annoyed and tried to push the person off him. Based on his experience, he believed that what was flying over was just some dust. Small fragments wouldn't even get through, let alone large fragments that could pose a threat to him. It was useless. He wasn't an impulsive person!
However, when he saw the people rushing towards him, Old Lin was stunned again.

"Liangzi, what kind of hero are you trying to be!"

You little brat, you weren't trying to beat me up on purpose, were you? That fall really hurt!
Whoosh, whoosh, whoosh... Several more people pounced over and pinned the two of them down. How old are they? What are they doing playing human pyramid?!

"Get out of the way, get out of the way!"

Old Lin got up, dusted himself off, and strode over.

In the center of the sturdy reinforced concrete fortification, a large hole several meters in diameter appeared, with cracks appearing in the surrounding concrete and the steel bars inside twisted and crooked, creating a truly spectacular sight.

Ten meters thick reinforced concrete, equivalent to a three-story building, was directly drilled through! What no one would have dared to imagine before, has now been achieved by a single cannon barrel!
"Comrade Qin Liang, your intelligence and talent are truly admirable!"

"Yes, not only can the monkeys' command center not withstand this attack, but those sturdy air defense command centers across the ditch also cannot withstand our attacks!"

In fact, the huge investment in building a similar command center here was not only for practicing how to fight monkeys, but also for preparing for the future. Across the river, in order to resist the military force of the mainland, a lot of air defense fortifications were also built, some of which were dug directly in the mountains, and some were built as sturdy fortresses underground.

Previously, the Air Force didn't have this kind of attack capability, but now, there's nothing to fear!

The army has a large number of Type 66 howitzers and many scrapped barrels. If a batch is modified, it can perform this mission!

With Northwestern Polytechnical University, no problem is insurmountable!
"Liangzi, if the enemy's fortifications are twenty meters thick, do we have any solutions?" Old Lin suddenly asked.

"Have."

"Thirty meters?"

"Also."

"Good, good, good!" Old Lin didn't ask any further questions. In his eyes, thirty meters was the limit.

In later generations, the Americans' most powerful GBU-57 bunker buster bomb, with a penetration depth of sixty meters, was designed to deal with cave fortifications. Later, they threatened to use this thing to bomb Lang Tuo's nuclear facilities.

If the Americans can do it, we can do it too, and we can do it even better!
"With Northwestern Polytechnical University providing technical support, we don't need to worry about any equipment issues! Let's go back, we need to have a good drink this time!"

"Report!" Just then, the secretary ran up.

"We just received word that people from the Russians have come to discuss further cooperation with Northwestern Polytechnical University!"

Old Lin was even more excited: "So, the Russians agreed?"

"When beating a dog, consider its owner." To teach a monkey a lesson, as the old leader would say, "If a child is naughty, give him a few slaps on the bottom." Such minor scuffles won't elicit a strong reaction from the Russians. However, if the commotion is too great and provokes their displeasure, it could escalate into a major conflict.

Even if the Russians get bogged down in Afghanistan, they can still export some weapons to the West, such as the Scud missiles, which would make the eastern border even more chaotic.

Only by reaching a tacit understanding with the Russians can we unleash our ultimate move.

Now that the Russians want to discuss further cooperation, they are naturally using the monkey as a pawn!
"Well, it seems I need to hurry back."

"That's right, let's go together!"

Northwestern Polytechnical University, university-run factory.

Looking at those powerful and imposing MAZ 543 off-road vehicles, countless people's eyes were filled with envy. This kind of vehicle is absolutely the most suitable for the military! There are no similar vehicles in China... However, this is not a big problem. At worst, we can take this opportunity to copy this vehicle.

"Gentlemen, our S-300 air defense missile system has been delivered in its entirety. Next, we hope that you can fully assist us in improving this air defense missile system. As for the research and development funding, according to the previous plan, we will transport all the necessary raw materials over. Our research and development progress must be prioritized and absolutely cannot fall behind."

"Of course, don't worry. Since it's been entrusted to Northwestern Polytechnical University, we will definitely complete it on time." Qin Liang was full of confidence: "This kind of project improvement is nothing to us. You've all come from afar, you must be hungry. Come on, let me take you to the cafeteria for some drinks!"

The first part says they're hungry, the second part says they're drinking. What does that mean? Does drinking alcohol guarantee you'll be full?

Engineer Chen knew that Qin Liang was setting the stage for him today, and from now on, he would have to take the lead. He would take the Russians drinking every day and night, drinking until they were drunk, and then drinking again after they sobered up. This way, the Russians wouldn't have time to keep an eye on things here, while his side could dismantle and study the S-300 missile system at will.

We also need to cut out a piece of the missile's solid propellant with a knife and hand it over to the relevant departments for research!
That's right, just like that!

"President Qin, besides the Diamond Design Bureau matter, we have other projects to discuss," Polyachenko said somewhat anxiously.

"No rush, let's drink first and talk while we drink!"

"Ok."

In the cafeteria, at the dining table, everyone had a bottle of baijiu. Qin Liang, holding his bottle, said in a very generous manner, "Come on, everyone, have a bottle first to soothe your throats!"

After saying that, he tilted his head back and gulped down...

Well, these Russians are really adorable; they never doubt what's in their bottles.

The Russians also drank straight from the bottle, but not many could drink a whole bottle; they were lucky to drink half. Many only drank about two ounces before putting down the bottle.

"President Qin, we also have anti-missile system development, and we'd like to cooperate with you to design an exoatmospheric kinetic energy interceptor for precise impact. This is no ordinary task..."

"The technical issues aren't the problem; the main problems are other aspects."

Seeing Qin Liang wave his hand, the old Russian naturally knew what it meant.

"General Qin, Moscow agrees to give the Vietnamese a symbolic lesson, which should not exceed one week, and the troops should not cross the existing front line by more than 100 kilometers..."

Ground troops?

"Yes, ground troops. As for air power, you can use it however you want, as long as you don't bomb Hanoi."

Sure enough, the Russians still have the traditional continental army mindset. In their eyes, the air force is just an appendage. Besides, didn't the Americans still fail after bombing Vietnam for so many years?
They don't care about the air force, as long as the ground troops don't go too far.

"Oh, there's one more thing. Right after you left last time, the Americans found out about our cooperation on the S-300 missile system. Do you... have anything to say about that?"

"What? Some secrets have been leaked?" The Russians' expressions changed.

"We will investigate thoroughly when we get back!"
