There was a roar in the sky, and the thick clouds made it impossible for people on the ground to see the planes on the clouds, but the huge humming sound that shook the sky made people feel a sense of devastating fear.

Above the clouds, at an altitude of 10,000 meters, twenty-four Great White Crane strategic bombers from the Tang Imperial Air Force appeared over Wu Harbor.

"Confirm that you have arrived at Kure Harbor and start carrying out the bombing of Jihua!"

In the first officer's seat, a colonel had just identified the area below as the Port of Kure, the most important base of the Japanese Navy, through maps and aerial photographs.

"The clouds will have an effect on my high-altitude bomb aiming!"

"It's okay, let's circle for a while, the level 6 northeast wind will soon blow the clouds away!"

"In that case, I am afraid that the Japanese will be prepared for evacuation and air defense, and the effect of our air raids may be reduced."

The captain and the vice-captain exchanged views and discussed countermeasures, but in the end, the more conservative captain made a decision, and everything was based on the objectives of the air raid mission and their own maximum safety.

"If we lower the altitude and go below the clouds, I am afraid that we will be attacked by the Japanese anti-aircraft artillery and cause losses, you must understand that our planes are different from the past, they are related to the core secrets of the country, once shot down, the core secrets may fall into the hands of the enemy. If the Japanese are allowed to develop long-range strategic bombers and high-precision bomb sights, it will be a catastrophe for the Tang Empire, because our land area is too small to withstand large-scale bombing. ”

Although the Great White Crane strategic bomber is a strategic bomber that the entire Shijie aviation community is crazy about and wants to obtain with all their might, Jishu, which can accurately drop bombs at an altitude of 10,000 meters, is the core of the core. It has made the military of various countries crazy.

Before the bombardiers of the bombers of the strategic air force were trained in precision bombing equipment, the bombardiers of the Tang Imperial Air Force had to swear to strictly keep the information about the secret equipment they came into contact with, and if necessary, even at the cost of their lives to protect the secrets from leakage. This particular equipment. It is a high-altitude bombing sight invented by Norton, a Dutch American.

It is not an easy task to accurately drop a bomb from a high altitude on a point-shaped target on the ground, especially in the thirties of the twentieth century, so that experts from various countries racked their brains and failed to develop it, but let the Tang Empire take the lead. If the bomb dropped by the plane is in pure ideal free fall, then the impact point may not be a big headache, but the key thing is that the plane is flying in the air, and the wind speed, wind direction, and aerodynamic characteristics of the bomb will all have an impact on the accuracy of the bomb. The most troublesome thing is. It is also difficult to directly measure the speed of the earth, which is the most critical speed of the bomb, or the speed of the aircraft relative to the ground, which causes a considerable deviation in the bomb delivery.

Karl, a Dutch-born engineer who worked at the Tang Imperial National Laboratory? Norton took a bold approach to this question. He designed a new type of bombing sight for the naval aviation of the Tang Empire -- the navy needed to carry out precision bombing of point targets on the sea. However, later the Datang Army Air Force also adopted this bombing sight with a novel design, and improved it, and finally applied it to the Great White Crane strategic bomber.

A complete set of Norton bombing sights consisted of two main components, a stabilizer and a sight. A stabilizer is actually a working platform that utilizes gyroscopes to stay level. Its role is to provide a stable datum for the sight. The stabilizer often works in conjunction with the bomber's autopilot. This allows the aircraft to be directly controlled to maintain horizontal flight. The sight Tang Jun used the combination of a star-ring mechanical sight and a front-mounted optical gyro sight, which can calculate the impact point accurately within 100 meters of error at an altitude of 10,000 meters, and the most important achievement of Shiyan is an error of 13 meters, which is the effect of the high precision of the optical sight. However, the disadvantage is that it will be affected by clouds, which is also a flaw of the optical sight.

"I understand the captain's concerns, so let's do what the captain wants. Anyway, our target is the Japanese naval shipyard in Kure Harbor and two Yamato-class battleships, and they won't be able to run away after a while. ”

"Maybe we can fly somewhere else and come back after the clouds have cleared for a while. Perhaps the Japanese thought that we were just passing by, and their air defense alarm was quickly lifted. ”

The captain suddenly made a new proposal. The vice captain's eyes suddenly lit up, and he immediately nodded in agreement, so the two of them discussed and decided, and the twenty-four Great White Crane strategic bombers quickly flew away from the sky over Wu Harbor and disappeared into the sky.

There was a panic on the ground of Kure Harbor, and when the siren sounded just now, tens of thousands of Japanese workers were frightened and fled for their lives, and the surrounding Japanese air defense units were also in place, loaded with guns, ready for air defense operations.

All the Japanese soldiers stared at the sky as if they were facing a great enemy, only to be stunned as the roar faded away.

"What's going on? Didn't you come to blow us up? ”

"The voice is gone, it looks like it's going in the direction of Hirado, could it be that it's going to attack Hirado?"

The Japanese commander in Kure Harbor was confused, but it was a good thing that the enemy planes did not attack Kure Harbor from afar.

Not long after, the air defense alarm was lifted in Kure Harbor, which could not be heard, and all the Japanese workers returned to work in the factories, especially the shipyards, and the second ships of the Yamato and Gozo had reached the zuihou stage, and the Japanese Admiralty urgently needed them to serve as soon as possible in order to turn the tide of the war, so the workers quickly returned to work on the second ship.

At this moment, the clouds in the sky had been blown away from the sky above Kure Harbor by a sixth-level wind, and the sky was clear. Such a good weather should have been in a very good mood, but soon the Japanese in Kure Harbor noticed that rows of bright silver points of light in the sky were rapidly approaching, and soon there was a terrifying humming sound for them.

"Yes - it's an enemy plane! He- they're back! ”

In the air defense post, the Japanese sentries had already spotted the Tang Army bomber group through binoculars, and this time they could see clearly that the behemoth was far larger than the Thunder Dragon medium-range heavy bomber they were familiar with before, that is, the rumored Great White Crane bomber that destroyed many cities in Spain.

After a few seconds of hesitation, the alarm sounded again.

This time many Japanese people are sluggish, and they have just returned to work. Even many of the Japanese air defense soldiers were also sluggish for a while, they did not understand why the alarm was sounded again, so they ran to their posts one by one with great reluctance.

"Damn it. How did you come back again? ”

The head of the Japanese commander suddenly became bigger, and he thought that Wu Gang was fine, but it was obviously impossible at this moment.

"Air defense battle, quick!"

When the order was given, thousands of anti-aircraft anti-aircraft guns around Kure Harbor opened fire violently, and countless shells shot into the sky, making the whole body tremble.

Boom! Boom!

The sky was filled with the sound of explosions. The high-altitude explosive shells fired by the Japanese anti-aircraft artillery were very powerful, relying on the kinetic energy of the shell fragments to attack the aircraft.

The 24 Great White Crane strategic bombers of the Tang Army were still flying calmly, like daytime cranes spreading their wings. The snow-white fuselage reflects the rays of the sun, making it very sacred.

The Japanese antiaircraft shells could not hit the air at an altitude of 10,000 meters, and exploded at an altitude of 8 or 9 thousand meters at most, producing black clouds of smoke.

The dense network of anti-aircraft fire looks very powerful. The Japanese commander saw that the Tang Army plane did not dare to descend to the altitude, and suddenly became satisfied.

"Over the years, we, the Great Japanese Empire, have endured humiliation. In order to prevent the Tang bombers from causing us fatal damage by another air strike, we spent a huge amount of money and tightened our belts to purchase such powerful anti-aircraft artillery. ”

The Japanese on the ground were very happy, and they applauded the powerful Japanese air defense. However, the next moment, someone suddenly screamed.

"Look, the Tang Army has opened the bombing hatch of the bomber!"

"Oh my God. Are they going to drop bombs at an altitude of 10,000 meters? ”

"They must be afraid of being shot down by our powerful artillery fire, so they can't wait to drop the bombs and return home."

"Don't panic. If you drop a bomb at that height, you won't be able to blow us up at all, and their aerial bombs will explode in mid-air. ”

The ability of the Tang Army's Great White Crane strategic bomber to drop bombs at an altitude of 10,000 meters was not known to the Japanese army, and the Tang Army had only secretly tested it on the mainland, and because Spain did not have a strong air force on the Spanish battlefield, the Tang Army did not need to drop bombs at an altitude of 10,000 meters at all, and the outside world did not know this secret.

"Target, ready to drop!"

The bombardier uses a sophisticated bomb sight to accurately lock on to the target that will be bombed, and then presses the bomb drop button.

…… Creak! …… Creak! ……

The aerial bombs, which had been fitted with time-delay fuses, slid out of the bomb bay one after another, emitted a sharp whistling sound, and fell towards the Kure Port Naval Shipyard.

Aerial bombs weighing 500 kilograms that fell from a height of 10,000 meters smashed down at an extremely terrifying speed under the acceleration of gravity, and the speed at the moment of landing exceeded 500 meters per second, and the dock platform with a thickness of up to two meters poured with reinforced concrete in the Wu Port Shipyard was instantly penetrated. Like a magnitude 8 earthquake, all buildings within a radius of several hundred meters collapsed in an instant, and everyone was shaken to the ground.

With a loud bang, the slipway more than two meters thick was blasted open, the steel was broken, the earth and stones flew wildly, and the smoke and dust filled the sky. The blast wave swept through everything, and all the people within hundreds of meters around were swept away, and countless broken bones and heart-rending screams were heard.

Squeaky ...... Rumble!

A destroyer under construction in the dockyard moved laterally from the base of the slipway due to a violent earthquake and flipped to one side, and hundreds of workers on it who did not have time to escape were smashed into the smoke and dust of the rubble.

Boom! Boom! Boom!

Aerial bombs were smashed down one after another, sending out earth-shattering explosions and roars, and the entire Kure Harbor Naval Shipyard was instantly plunged into a monstrous sea of smoke and dust.

The battleship Yamato and the battleship Gozo were the objects of special care, and most of the aerial bombs bombarded the hulls of these two super battleships. The aerial bombs descending from a height of 10,000 meters carried terrifying gravitational acceleration and penetrated the horizontal defensive armor as high as 230 millimeters thick without much effort, and the 500-kilogram aerial bombs exploded inside the giant ship, causing fatal damage to the super giant ship that had taken many years to be completed.

The Yamato was much worse than the Gozo, it was hit by eighteen 500-kilogram aerial bombs in less than a minute, the barrels of the giant main guns that were more than ten meters long and weighing hundreds of tons were twisted into twisted shapes, the entire superstructure was razed to the ground, the deck was full of huge craters with a diameter of several meters, the fire was blazing, the smoke was billowing to cover the sky, the horizontal deck of the entire battleship was completely destroyed, and the steel armor hundreds of millimeters thick around it were all rolled up, like leather shoes with mouths open on all sides.

Several aerial bombs fell on the surrounding water, stirring up huge waves hundreds of meters high, causing the Yamato, which had lost its horizontal structural balance, to suddenly topple up, and the sea water overflowed, pouring tens of thousands of tons of seawater into it in just a few minutes, causing the Yamato to finally topple up, and half of the ship's hull was submerged in the sea water and fell into the silt.

The Wuzang was only hit by eleven aerial bombs, and the same superstructure was destroyed by the blast wave, and the hull was blown open one by one, and the whole ship was on fire. Although it was badly damaged, it was only fortunate that it did not overturn.

All the aerial bombs dropped by the Tang army in the first few minutes were high-penetrating aerial bombs, and the purpose had been achieved, which was to severely damage the Yamato and Gozang. Next, the 24 Great White Crane strategic bombers of the Tang Army dropped more than a dozen white phosphorus bombs.

The production volume of this white phosphorus bomb is not large, so each big white crane can carry dozens of them, because the white phosphorus bomb itself requires to be released in mid-air, and it is a weapon of mass destruction, so the Tang army did not need to drop the height directly at an altitude of 10,000 meters.

The white phosphorus bombs exploded in mid-air, blooming like fireworks, and the fragments dragged a long tail of white smoke and scattered around the entire Kure Harbor Naval Shipyard, houses, slipways, gantry cranes, warships, personnel, and all kinds of shipbuilding equipment and materials were immediately corroded and ignited, and tens of thousands of Japanese fighters and shipyard workers were killed and injured by the white phosphorus bombs to varying degrees, the light ones were burned through a hole, and the heavy ones were crippled and died. A lifetime of living in fearful memories.

At the same time that the Japanese Kure Port Naval Shipyard was attacked by the Tang Empire, the Yokosuka Shipyard in Tokyo Bay was also bombed by a large number of Tang Army bombers, and the entire Yokosuka Shipyard was blown up like the Kure Port Shipyard, and the most distressing thing for the Japanese army was that the two sister ships of the Yamato, Shinano and Hitachi, were also heavily damaged, with a damage rate of as high as 55%, and the Japanese army worked hard to build for four or five years, spending hundreds of billions of yen, and was ruined by the Tang Army.

What made the Japanese army's spirit collapse even more was that the air defense unit they had invested heavily in failed to shoot down a single Tang Army bomber, but instead tens of thousands of Japanese soldiers and shipyard workers were killed and wounded, and the price could only be expressed in a tragic way.

The Don Army is the devil! (To be continued......)
