As the small islands around Oahu fell one by one, the Japanese side was given more front-line field airfields. After 15 November, due to the loss of air defense depth, the activities of the US air force in the skies over Hawaii were completely suppressed, and now Japanese fighters can hover over Oahu 24 hours a day, and the "sense of survival" of the US air force in the Hawaii area is close to zero.

"Quick, clear the runway, the thunder is coming!"

After more than 40 days of renovation and construction, Kauai Island, which was seized by the Japanese at the end of September, has two more hard runways 1,000 kilometers long on the island, which are strong enough to take off large four-engine bombers. On the island's man-made docks, the Japanese military has also built and installed special crane platforms that can lift heavy equipment directly from the ship to Kauai Island.

The HE177 four-engine heavy bomber sold by Germany to Japan was named Angry Thunder by Li Huamei. After several months of flight training, Japanese pilots had mastered the heavy bomber proficiently. The first batch of 10.5-ton "Big Herax bombs" prepared for the bombing of Oahu was also delivered to Kauai the day before yesterday.

In order to facilitate the loading of this 10-ton super aerial bomb, the Japanese military even transported steel rails and sleepers from the mainland to build a small light rail railway more than 400 meters long on Kauai Island. Because the small islands around Pearl Harbor are actually too close to each other and vulnerable to attack, they are not suitable for heavy bombardment. Only Kauai is relatively far away (about one hundred and fifty kilometers from Oahu) and has a certain depth of air defense warning. In order to ensure that Kauai Island was protected from US air raids, the Japanese military set up radar stations and hedgehog-dense anti-aircraft artillery positions on the island. （）

At noon on the 15th, there was a buzzing sound in the sky west of Kauai Island, and a full fleet of 24 HE177s flew over the island, and then landed on the island one by one under the guidance of ground air traffic control.

After the plane landed. The ground crew immediately rushed to the station and began to maintain these precious imported heavy bombers. By the time dawn tomorrow, these 24 HE177 Thunder bombers will all start bombing Pearl Harbor.

On 10 November, the United States and Japan briefly ceased fire on Oahu for 24 hours, in accordance with a prior agreement. Several passenger ships then entered Pearl Harbor. Carrying the island's indigenous people, two of these passenger ships came from Australia and the rest from the United States.

Half of the inhabitants of Hawaii were Japanese-Americans, and after the U.S.-Japan war was declared, the Americans on Hawaii Island put these Japanese in concentration camps out of distrust.

According to the agreement reached between the United States and Japan, those Japanese expatriates who wish to return to Japan can return to Japan on a ship from Australia.

After the outbreak of the Battle of Hawaii. Large numbers of American civilians are stranded on the island of Hawaii and unable to leave. The Japanese side agreed to the US withdrawal of civilians, not because they were kind, but because they did not want to strengthen the determination of the US troops stationed on the island to defend Hawaii because of the existence of these civilians, and at the same time, it was also convenient for the next step to use "weapons of mass destruction" on the island without worrying about accidentally injuring civilians.

In this Hawaiian campaign, the German side regarded him as a testing ground for a variety of new weapons, and what Germany sent over was not only a powerful concrete drill like the Great Herax. There are also several other "conventional weapons of mass destruction" that were born in later generations, which can be used as an experiment on this fortified Oahu.

And Li Huamei is here. She plays the role of "the crystallization of the faith of the Japanese people" and also has the "obligation" to care about the safety of the Japanese expatriates on the island.

At half past seven o'clock in the morning of November 16, the supreme commander of the defenders of Pearl Harbor was disturbed by a buzzing sound coming from his head.

The humming sound of the propeller is different for different aircraft. Since the Battle of Hawaii began, he has heard the buzz of various aircraft, but today is different. It's denser than you've ever heard. It's also harsher, a bit like the sound made by the B17.

Soon, including Lieutenant General Short, everyone saw a group of planes flying from the northwest that was significantly larger than the fighter plane. Lieutenant General Short picked up the binoculars and looked at it, and soon saw that it was a bomber with four engines.

During the past three months of war, although Oahu was the ultimate target of the Japanese army, there were not many aerial bombs on the island. The Japanese side was reluctant to expend precious aircraft and pilots on this "spiky" fortified island. They usually only fire a few random rounds at the island when they are "passing by" in air combat. Even if there was a bombing campaign against the island, it would only be a small group of two or four planes, choosing to fly over the sea in the early hours of the morning or dusk to avoid radar, and then burst into the island and drop a few bombs or rockets indiscriminately before quickly withdrawing.

Because there are not many fighters and pilots left on the island, and Japanese fighters have always occupied the airspace over the island for a long time. Normally, even if the defenders of Pearl Harbor sent planes to fight, they chose to attack with planes at night when visibility was extremely poor.

Today is no exception, in the face of the HE177 that is about to fly overhead, what Lieutenant General Schott can do is to issue an island-wide air defense alert, but he did not send a plane to intercept it.

The fortress was over Hawaii, where the Japanese had gained air supremacy. Now all the defenders of Oahu can do is use the island's 90-millimeter anti-aircraft guns to carry out dispersal artillery bombardment against the sky group, but the effect is very poor.

When the anti-aircraft artillery on the island began to work, the United States suddenly discovered that the artillery sighting radar used in conjunction with the antiaircraft artillery was suddenly covered by a snowflake. Although this kind of artillery sighting radar is still very primitive and has a large error, after encountering strong interference, the artillerymen can only rely on primitive optical sighting equipment. At this time, the US Navy and Army had not yet developed VT radio proximity fuzes, and the Navy and Army could only rely on primitive timing fuses for air defense, and the air defense efficiency was very average.

The HE177 Thunder heavy bomber, lined up in two long columns, twelve in each column, passed through the anti-aircraft artillery fire that bloomed in the air like flowers, and then opened the bombing single pylon at an altitude of 5,000 meters.

A full twenty-four 10.5-ton bombs with wind whistles fell from the pylons, and a piercing screech resounded through the sky.

Compared with the bombing of the fortress of Gibraltar two years ago, many aerial bombs fell into the sea because of the immaturity of the bombing sight technology, and this time the huge aerial bombs dropped from a height of 5,000 meters all successfully landed on Oahu.

"Boom!" "Boom"!

Oahu resounded with a terrifying bang, and each huge bomb weighing more than ten tons pierced into the ground and exploded violently, causing the defenders on the island to hallucinate about a major earthquake.

The 10.5-weight giant aerial bomb loaded on the HE177 is a super aerial bomb made with reference to the design ideas of the Grand Slam aerial bomb developed by the British in history. The body includes a tail with a length of 8.15 meters and a diameter of 1.17 meters, and the head is protected by a reinforced cone. When falling from a height of 5 thousand meters, the penetration force of the soil layer is more than 40 meters, and the penetration depth of the concrete layer can reach 6 meters.

After the twenty-four giant bombs fell one after another, accompanied by an earth-shattering loud sound, there were twenty-four more huge craters the size of swimming pools on Oahu in an instant.

The forts on Oahu are even more perverted than those in Gibraltar, and some of them are even built directly in the belly of the mountainside, with hundreds of meters of rock and soil on top. For these batteries, even the "Great Herax" can only look at and sigh.

However, not all of the batteries were built in these positions, and most of them were still within the strike range of the "Great Herax".

Two years earlier, during the war in Europe, when the Germans were bombing Gibraltar, they had planned to forcibly smash the fortress with thousands of "Heraxes", but this idea was ultimately abandoned due to the submission of the British. In this Hawaiian war, the Japanese, according to Li Huamei's opinion, also planned to drop more than 2,000 large Heraks on Oahu, and before the landing battle, they would first use this super aerial bomb to pull out most of the thorns on Oahu.

On 16 October, the Japanese airfield on Oahu took off three waves of HE177s with a total of 70 or 20 sorties, and dropped 72 10.5-ton large Herax bombs on Oahu in one go.

Japan's weak industrial strength made it impossible to produce such a super bomb for the time being, and its shell had so far been supplied by the Germans. By November, the Germans had shipped more than 2,000 shells from the mainland, which were then sent to Hawaii by Japanese ship-filled firearms.

During the 16th bombardment, HE177 was aimed at the crater on the island, with the goal of destroying the mortars in the crater. Although none of the bombs dropped that day hit, shocking craters were planted in the land around the crater.

The biggest achievement of the bombing that day was twofold: one of the huge bombs landed near an anti-aircraft artillery position on the island, and the antiaircraft artillery company was swept away by this bomb.

Another bomb landed in a barracks, and 100 people in the camp were shattered in a loud bang, and they were too dead to die.

When the first Great Herax landed on Oahu with a terrifying scream, witnessing the huge black smoke rising from its explosion, and seeing the huge holes in the ground like turnips afterwards, the Supreme Commander of Oahu, Short, turned pale as paper on the spot.

He knew in his heart that this was just the beginning. Over time, the Japanese would drop more super-bombs on the island.

That night, Washington received an urgent telegram from Lieutenant General Short, saying that President Wilkie was also very nervous after learning that Japan had used super aerial bombs to bomb Oahu, and this bad news also affected the US Navy's next military action plan. (To be continued......)
