Glorious Mission 1937

The so-called Manhattan Project is actually the U.S. War Department's plan to develop an atomic bomb. In early 1939, German chemist O. Hahn and physical chemist F. Strassmann published a paper on the phenomenon of uranium nuclear fission.Within a few weeks, scientists from many countries verified this discovery, and further proposed that it is possible to create the conditions for the self-sustained fission reaction, thus opening up a broad prospect of using this new energy source to create wealth for mankind.

However, like many new scientific and technological discoveries in history, the development of nuclear energy was first used for military purposes, that is, to manufacture powerful atomic bombs, and its progress was affected and restricted by the social and political conditions at that time.And Germany began to implement the "Uranium Project" as early as February 1937, with the purpose of creating an atomic bomb.

Because Hitler brazenly launched a war of aggression against Europe, a large number of European scientists headed by physicist J.-f. Joliot Curie were forced to emigrate, and these people mainly immigrated to the United States.In the United States, Zirad Leo, a Hungarian physicist who moved from Europe, first considered that once fascist Germany mastered the atomic bomb technology, it might bring serious consequences.

Promoted by Chirad Leo and several other scientists who immigrated to the United States from Europe, physicist Einstein wrote to President Roosevelt in August 1939, suggesting the development of an atomic bomb, which attracted the attention of the U.S. government .

However, because the U.S. government was not very interested in this, it only allocated $6000 in funding at the beginning. It was not until after the Japanese attack on Pearl Harbor that the scale was expanded. In August 1942, it developed into a huge project code-named "Manhattan Engineering District".About 8 people were directly employed, with an investment of more than 60 billion US dollars.

In order to manufacture the atomic bomb before Nazi Germany, the Manhattan Project gathered the best nuclear scientists from Western countries except Nazi Germany at that time, and mobilized more than 10 people to participate in this project.

According to the original historical development, the Manhattan Project lasted 3 years and cost 20 billion US dollars. Finally, on July 1945, 7, the world's first nuclear explosion was successfully carried out, and two practical atomic bombs were produced as planned. The entire project A complete success.

But due to the appearance of Chen Feng, a lot of history has undergone fundamental changes.Especially the early outbreak of World War II and the early outbreak of the Pacific War.The Manhattan Project in the United States was greatly advanced, and it entered the explosion test stage 11 months in advance. As long as the test is successful, a practical atomic bomb can be manufactured.

In the early hours of July 1944, 7, in a desert area of ​​Alamogordo, New Mexico.With a huge mushroom cloud rising.The world's first atomic bomb test was successful.

Originally according to the meaning of the scientists.After the successful experiment in the desert area, a sea test explosion experiment will be carried out in the atolls of the Pacific Ocean, but it was rejected by President Roosevelt.He ordered the headquarters of the Manhattan Project to immediately assemble a functional atomic bomb.

On August 1944, 8, Roosevelt called Chen Feng, Stalin and others, inviting them to Washington, USA to hold a war meeting against Japan, and Chen Feng and others happily went.

In Washington, Chen Feng and others received warm hospitality from the U.S. government. On the morning of August 8, as soon as the meeting started, Roosevelt distributed a stack of materials to Chen Feng and others.

Seeing the huge mushroom cloud picture on the document, Chen Feng felt a "thump" in his heart, knowing that the United States had finally successfully manufactured the atomic bomb, and it seemed that the landing operation might be cancelled.

Sure enough, after Chen Feng and others read the document, Roosevelt told the news of the successful atomic bomb test to several people present. Among the leaders of the countries and countries present at the meeting, only China did not carry out research on the atomic bomb. Both Britain and the Soviet Union had their own research. The "Manhattan Project", so after learning that the atomic bomb test was successful, Stalin and others were surprised, happy and worried.

The atomic bomb is not an ordinary bomb. Although Stalin and others don't know its power, according to the estimates of scientists from various countries, just one such weapon is enough to destroy a city with a million people, which is extremely terrifying.Now the United States has taken the lead in mastering this weapon, which is definitely a great threat to the Soviet Union.Fortunately, the two sides are allies now, and the atomic bomb will not fall on the heads of the Soviets for the time being.

Just as Chen Feng thought, Roosevelt proposed to use atomic bombs to destructively attack the main cities in Japan before landing on the Japanese mainland. After destroying the effective forces of the Japanese army, the landing operations will be carried out, so that the losses of the Allied forces will be much smaller.

Chen Feng discovered that Roosevelt actually didn't know much about the performance of the atomic bomb, or that he didn't have much confidence in the power of the atomic bomb, so he didn't plan to stop the landing, but wanted to do both.

Chen Feng was secretly happy that after the Japanese tasted the power of the atomic bomb, they might surrender without landing. The preparations of the Allied forces in the early stage were in vain, but he didn't say that.

According to the agreement between China, the United States, the Soviet Union, and Britain, each of the four countries dispatched 80 troops and 500 ships to approach the Japanese archipelago from east, west, north, south, and four directions, preparing to land on the Japanese mainland on August 1944, 8.Prior to this, on August 22, the U.S. military will drop an atomic bomb on Tokyo, the capital of Japan, and two other cities in order to attack the Japanese government's confidence in resistance.

On August 8, Chen Feng returned to Chongqing from Washington, and communicated with the government on the same day. He told Mao Zhou and others that Japan’s surrender was imminent, and the Chinese government should do a good job in prosecuting senior Japanese military officials, politicians, and big businessmen. , and can begin to count China's war losses.

1944年8月15日早晨8时整，美军393d轰炸中队的b-29艾诺拉.盖伊号从天宁岛北田空军基地起飞，飞行时间约6个小时。艾诺拉.盖伊号与查尔斯.w.斯威尼少校指挥的科学观测机大艺术家号及乔治.马夸特上尉的摄影观测机一同前往日本东京。

Three U.S. b-3 planes entered Japan's airspace from a high altitude. Why do you say again?It is because during this period of time, Allied fighter planes have carried out uninterrupted air strikes on the Japanese mainland, with hundreds of fighter planes moving.Now the Japanese government has almost taken an indifferent attitude towards the sporadic Allied fighters entering Japanese airspace.

According to the plan of the U.S. military, after the B-29 bomber loaded with atomic bombs enters Japanese airspace, it will determine the bombing location by itself according to the weather conditions. Washington only gave the approximate areas of Kyoto, Hiroshima, Kokura, and Yokohama.Among them, Kyoto City (Tokyo) is an AA-level target, Hiroshima City is an AA-level target, Yokohama City is an A-level target, and Kokura City is an A-level target.

On August 8, the weather in Tokyo was fine and cloudless.Shortly after the U.S. warplanes entered Tokyo airspace, Japan's early warning radar detected some U.S. aircraft approaching southern Japan.Air raid warnings were issued in many cities.Including Tokyo and Hiroshima and Yokohama.

But surprisingly.At close to 9:20 am, radar operators in Tokyo decided to cancel the air raid alert because the number of enemy aircraft entering Japan was very small according to the signal displayed on the radar.Probably no more than three.In order to save fuel and aircraft.Japan has decided not to intercept small aircraft formations.

But the radar operator called the anti-aircraft battery instead.They were asked to enter a state of alert. Once the enemy plane entered the urban area of ​​Tokyo, the air defense forces immediately fired back.

Since the air defense siren was disarmed.So the Japanese people on the ground didn't care, because they learned from the broadcast that there were only three enemy fighter planes this time, and their own air defense forces were already in place, and they would surely shoot down or drive away the enemy soon.Therefore, almost all citizens in downtown Tokyo are working normally.

At 9:50:33, the collimator on the U.S. plane loaded with the atomic bomb was aimed at the Japanese Kyoto Garrison Command and the nearby Japanese military camp, and the automatic bomb-dropping device was activated. After 60 seconds, the atomic bomb fell into the air through the open hatch.At this time, the plane made a 155° turn and dived down; in an instant, the flight altitude dropped by more than 300 meters.This is done to keep the explosion site as far away as possible.

45 seconds later, the atomic bomb exploded in the air 600 meters above the ground, immediately emitting a dazzling and intense white flash, and a deafening explosion occurred over the center of Tokyo.In an instant, a huge mushroom-shaped cloud of smoke suddenly rolled up in the city, and then hundreds of fire pillars were erected, and Tokyo was immediately reduced to a scorching sea of ​​flames.

Due to the crosswind, the atomic bomb deviated about 500 meters from the garrison headquarters of the aiming point, and detonated 600 meters above the Japanese Army University.It has an explosive yield of 16 tons of tnt.The total damage radius is about 000 kilometers, and fire broke out within 1.6 square kilometers.About 11 square kilometers of the urban area were destroyed, and about half of the buildings in Tokyo were devastated.

The intense light waves produced by the atomic bombs blinded tens of thousands of people; the high temperature of 10 billion degrees reduced everything to ashes; the strong winds formed by the shock waves destroyed all the buildings.People and things under the influence of the epicenter are disintegrated like atoms separated.A little farther from the center, the remains of men and women and children can be seen that were burned in a split second.In a place farther away, although some people were lucky enough to survive, they were either severely burned, or their eyes were burned into two holes.People can still feel the sweltering air from 16 kilometers away.Due to the dense population of Tokyo, the explosion caused nearly 10 direct deaths, and nearly 10 people were injured in the atomic bomb explosion and the resulting storm.

Less than two hours after the atomic bomb exploded, the governments of China, the United States, the United Kingdom and the Soviet Union issued a statement again, urging the Japanese government to surrender immediately and unconditionally, otherwise it would be dealt a severe blow.

However, the tragedy in Tokyo did not immediately lead Japan to accept the Allies' ultimatum and unconditional surrender.The Japanese government and the base camp tried their best to cover up the truth of Tokyo, claiming that a meteorite fell in Tokyo.

Japanese intelligence agencies believed that the United States did not have much raw materials to make atomic bombs, and believed that the US military had only one atomic bomb, so they refused to surrender unconditionally.

1944年8月17日，美军又在日本长崎和广岛各投下一原子弹。两大城市一天内便有15万人丧生，另外还有5万人在随后的3天中死亡。

On the afternoon of the 17th, the allies once again issued an announcement to urge the Japanese government to surrender immediately and unconditionally. Otherwise, Yokohama and Kokura would be the next targets. The allied forces gave the Japanese government three days. If the Japanese government did not give a clear answer after three days, the allied forces It will carry out a landing operation while carrying out a nuclear strike against Japan.

On August 1944, 8, the Japanese Emperor issued a surrender edict, announcing unconditional surrender. (To be continued..)
