Jia Xiaohou said it simply, but in fact, the use of 20-gauge ammunition is very complicated. A dive at an altitude of 4,000 meters alone is not something that ordinary pilots can control. Not to mention that the dive speed must be greater than 850 kilometers, and the angle must be more than 80 degrees. You know, the fortress is not a battleship, and the maximum can only park three trucks on the top. In the simplest terms, it is to align a sesame seed from 4,000 meters, so you can imagine how difficult it is.

But there are always some alternatives in this world, such as Liu Cuigang. He is not only a recognized beautiful man in the Air Force, but also a special pilot, and of course, an alternative. Let's drive the fighter well, since Afghanistan has been 17 shot down, but after the East Kazakhstan Campaign, because the Soviet Air Force was completely defeated west of the Aral Sea, and there was no offensive mission there, so I felt bored and stuffed cigarettes to find a way, and finally temporarily transferred to the dive group. As a result, this tune is incredible, in just 2 months, a record of 27 missions without a single miss. And most of the targets are exposed small-volume tanks and solid bunkers. So when it came time to choose someone again, he was chosen first. Of course, at that time his altitude base was 1,500 meters, and now he has to rise to 4,000 meters, and he is a little nervous. So I turned on the communicator and asked my naval colleagues who had participated in the experiment: "Shaobao, you were like this during the experiment?" It was too heavy, the lever was stiff, and the climb was slow, which caught up with the ox cart. Liu Cuigang said as he tapped his fingers on the snail-like ceiling watch, very suspicious that it was broken.

"It's fast enough. I said last time, how good is it to just change the engine? These guys say they don't have enough time. Damn, I'll settle accounts with the fuck later. The voice of Lei Shaobao, a naval pilot who participated in the development of the No. 20 bomb, came from the earphones. Liu Cuigang laughed secretly, how can the navy be so virtuous? He knew that Lei Shaobao was a living treasure in the navy, but his excellent skills made several generals helpless. In addition, his father was Yang Qiu's personal guard Lei Meng back then, so he could only turn a blind eye.

But Lei Shaobao didn't have this awareness, and his mouth was still unclean: "I know that those old men are actually not well-intentioned, and they are afraid that I will be driven out by accident." Grandma's, when I get back, there will still be two bombs on their heads. "To say that Liu Cuigang also cooperated with the navy, since the war between China and the Soviet Union, the idle navy sent pilots to Central Asia in turn to master actual combat experience, but for the first time encountered the best who wanted to throw bombs on the heads of his own troops. So I hurriedly turned off the radio and chose not to listen to it.

Forty minutes later, the three ghost cars slowly climbed to the predetermined height. Five minutes later, the dive bombers, which had taken off first, were the first to aim at the main fort with 305 mm fort guns from low altitude. A strange screech reappeared on the battlefield as a ghost car began to dive. It also attracted a counterattack by Soviet anti-aircraft fire. Boom and Boom burst out of the mountain next to the fortress, and a moment later the anti-aircraft machine guns inside the fortress also joined in, pulling a dense rain of metal bullets above the fortress. However, compared with some time ago, the continuous shelling of the railway artillery has weakened the anti-aircraft fire a lot, and the ghost car that dived at high speed was not greatly disturbed, but accurately threw a gel smoke bomb on the top of the fortress.

This gel smoke cartridge is specially made, and it is filled with nothing but ignition white phosphorus. Most of them are a viscous substance similar to heavy oil, which adheres to the surface of the fort for a long time after ignition and emits a striking orange-red smoke that allows pilots at high altitudes to see their targets. After the group below began to attack. Liu Cuigang turned on the radio again, and waited until the orange smoke appeared, and the sound of the battlefield observation plane "can bomb" came from the earphones. As usual, he first tilted the fuselage with a deflected rod. In order to allow the engine and carburetor to fully familiarize themselves with the strenuous movements. But this time, the ghost car that sat down was not very obedient, and it took more than half a circle before leaning over. Looking down from the cabin. The whole earth is curved, and the vision is distorted and blurred. While he was making preparations, a group of dive bombers was also on standby.

The bombing was a series of air force dive tactics, with a total of 42 naval and air pilots participating. According to the plan, the target was first locked with gel smoke bombs, then the No. 20 bomb "kicked the door", and finally the special 500-kilogram No. 22 aluminum-magnesium mixed deflagration bomb. This kind of bomb can instantly release a high temperature of more than 3,000 degrees, and even steel will be melted.

The orange-red smoke and the large number of planes hovering overhead made the Soviet troops inside the fortress feel bad for the first time. "Hurry! Go up and extinguish it. "The company commander Andreev of the anti-aircraft company acted the fastest, immediately having people pumping water from the fortress and trying to extinguish the smoke. But when the water cannon rushed up, he found that the flame attached to the cement not only did not extinguish when it encountered the water, but emitted a thicker smoke. "Cover it with dirt, and get a shovel." Andreev shouted for the sapper shovel, but he didn't know that death was already whistling.

The height was too high, and the ghost car was not equipped with a Stuka pronunciation, so the Soviets did not pay attention to it at first, and it was not until it was close to two thousand meters that the anti-aircraft guns noticed the lone bomber. "Machine gun, aim at the target! Fire, fire! Don't be afraid, they can't blow up our fortress. "The bomber overhead made Andreev not bother with the overlay and jumped into the air defense platform to direct the machine guns. The soldiers operating the machine guns were used to the bombardment overhead, and under the protection of thick cement steel plates, everyone did not take it too seriously.

While Andreev commanded three water-cooled heavy machine guns to fire, Liu Cuigang was fighting with the ghost car. Because the No. 20 bomb was too heavy, the plane almost immediately fell down after he pushed the rod, and the speedometer instantly changed from 300 kilometers per hour to nearly 900 kilometers per hour! Although the ghost cars that threw the No. 20 bombs were all reinforced and modified by the fuselage, the dive speed of 900 kilometers was enough to cause the flight to disintegrate! And because of the weight of the bullet, the flight path is extremely unstable when diving, and the operating lever is stiffer than an iron bar! "The airbrake is ajar! Do not go into the spiral with the tail rudder control! Turn on the auto-changer early! At this time, the most experienced Lei Shaobao found out that something was wrong and immediately shouted to warn him.

The sound saved Liu Cuigang's life, he quickly opened the speed brake ajar, put his fingers on the red automatic change button, and stepped on the tail rudder plate with both feet to prevent the plane from entering the spiral. As the distance got closer, the fortress in the eyes became more and more flowery, and the orange-red smoke had even turned brown. He understood that this was a common black vision phenomenon during high-speed dives, but it was just that this time the bomb was too heavy and the dive speed was too fast.

The shells exploded around him, and the gray smoke was as brilliant and deadly as a salute flower, and from time to time a small crash could be heard from the armor.

Everyone who saw this scene was heartbroken. From the perspective of the ground, Liu Cuigang and his ghost car are like a rocket falling vertically, roaring down from 4,000 meters at a vertical angle of nearly 90 degrees! “1200、1000、700。 Liu Cui just stared at the counter, and if he wanted to accurately hit small and medium-sized targets, he had to drop bombs at a low altitude, and it would take at least 300 meters to deal with the narrow flat roof of the fortress. So when they set off, they decided to control the height of the bomb to 300 meters.

When the counter flashed to 300 meters, Liu Cuigang pressed the bomb button. After a slight shock to the fuselage, it was as if a thousand pounds of weight had been lifted. Decelerates suddenly, the automatic changer senses the bomb disengagement, also stretches the honeycomb speed brake to the maximum, and then controls the air flow under the flap to lift the nose of the aircraft. "Get up, get up! Get up! "The auto-changer responds slowly. Liu Cuigang and everyone couldn't help but drink violently, and when they saw that the plane was about to hit the fortress, the bomber finally moved, and changed its dive state with an almost V-shaped action. Countless shells and bullets chased the ass of the plane, but by this time it was already too late.

The sharp warhead, which had a large amount of tungsten powder and hardening, easily broke through the first layer of cement, and when the balance wing of the tail of the projectile was torn apart, the head had already passed through the 150mm steel plate. Of course. All this was indistinguishable to the naked eye and ears, and the company commander Andreev only heard a rumbling crash, and then the fortress behind him was covered in smoke and dust. In the retina, only a black afterimage tore through the ceiling at high speed. Then it quickly disappears downward.

The power of the No. 20 bomb was staggering, and although it was somewhat less powerful than the 22-ton model of the later generation, it still penetrated the second layer of cement slab inside the fortress and exploded after hitting the third layer. "Boom!" The enclosed space grows the power of 28 kg of inert TNT. In an instant, the two-meter-thick cement leak board on the second layer was blown away, and the gushing shock waves and fireballs continued to spread and eventually permeated the entire space. In the end, the top cover with a five-meter-thick steel plate interlayer poked a hole with a diameter of four meters! A huge fireball soared into the air at a height of 100 meters!

Later actual surveys proved that the No. 20 bomb dropped by Liu Cuigang not only penetrated the top cover, but also penetrated the second layer of 2 meters of cement, and exploded only after hitting the third layer of damaged structures, and the actual total penetration depth was close to an astonishing 6 meters of reinforced cement mixture (at that time, the cement mark was low, and one meter of modern special cement was about 2.5 meters at that time).

"Hit! Hit! Haha hit! The fireball that suddenly poured out from the top of the fortress made Dai Jintang and other officers in the battlefield observation plane, who had been holding back for a month, shout wildly. But for Andreev and the Soviet soldiers inside the fortress, the horror had just begun. Due to the internal twists and turns and the multi-layered structure, the No. 20 projectile, which had a small charge, did not completely destroy the bottom layer. When Andreev wiped the blood from his face and ordered everyone to prepare to escape, a second dive bomber with a No. 22 aluminum-magnesium mixed deflagration bomb descended from a low altitude and accurately dropped the bomb into the gap.

Unlike a ground-penetrating bomb, a deflagration bomb explodes immediately after hitting a damaged second layer of steel bar. The powder mixed with special substances such as aluminum and magnesium spread rapidly in the explosion, instantly turning into a huge expanding fireball. In an instant, the entire fortress was filled with flames, and all the zigzag bunkers and internal rooms did not escape the flames. Before Andreev even felt it, his body quickly shrank and turned into a fireball. What's even more terrifying is that the flames of up to 3,000 degrees also burned through the lowest fire door and entered the warehouse where a large amount of propellant was hidden.

"Boom." Like an earthquake, more than 200 305-mm grenades and propellants were detonated by the flames, and the cement roof weighing hundreds of tons was completely lifted off, and the entire fortress was like an egg that exploded inside, suddenly expanding and turning into a ball of fire. The soldiers on the ground who couldn't see clearly just now were also stunned, no one thought that the fortified fortress that had plagued them for a whole month and left a total of 700,000 soldiers in the six armies helpless would be completely wiped out so easily! The mushroom cloud, which is more than 500 meters high, announces the end of the fortress era!

Liu Cui, who was drenched all over his body, returned to the height, stared at the destroyed fortress, and clenched his fists fiercely: "Shaobao, it's your turn." ”

"Just look! The second machine is in place, and the gel smoke bomb guides Lao Tzu to come! ”
