Iron-blooded Hero Li Yunlong

Soon, after several hours of sailing, everyone arrived at the Bohai Strait.

The Bohai Strait is the second largest strait, located between the Shandong Peninsula and the Liaodong Peninsula, and is the dividing line between the Bohai Sea and the Yellow Sea.It is the only channel for sea transportation inside and outside the Bohai Sea.

Strategically, the Bohai Strait is an important place for coastal defense. There are more than 10 large and small waterways, which are the throats of the Bohai Sea and the sea gateway of Beijing, Tianjin and Hebei.Strategic position is very important.

"Report to the commander, the four Bohai Straits ahead!" Xie Qian reported loudly.

"Is there no problem for the Qianlong to pass through the Bohai Strait?" Li Yunlong asked loudly.

"Report to the commander, there is no problem!" Xie Qian said: "It's just that most of the Bohai Strait is occupied by the Japanese army. When we pass through, in order to reduce the possibility of being discovered, the speed will be slowed down!"

"Yes, the concealment of the submarine is the first priority!"

"Yes!"

Immediately, the speed of the Qianlong nuclear submarine slowed down, slowly passing through the Bohai Strait.

After passing through the Bohai Strait, it enters the Yellow Sea.

The Yellow Sea is a marginal sea in the western part of the Pacific Ocean. It is a semi-enclosed shallow sea approximately north-south.The average water depth is 44 meters, and the water color of large areas of water is yellow.

"The sea ahead is the Yellow Sea!" Xie Qian kept reporting Qianlong's advancing position.

Li Yunlong nodded, the speed of the Qianlong nuclear submarine is still very fast!

Since the Yellow River has flowed into the Yellow Sea for more than seven or eight hundred years in history, the large amount of sediment carried in the river has dyed the seawater near the Yellow Sea yellow. This is very suitable for the stealthy operations of submarines, and the sea area is about More than 8 square kilometers, with an average water depth of 40 meters and a maximum water depth of 86 meters.This is also very conducive to the advancement of submarines.

"Buzz...huhuhu..."

In the area of ​​the Yellow Sea, Qianlong increased the speed to the highest 40 knots, and quickly shuttled through the water.

Although there will be warships invaded by the Japanese army on the surface of the Yellow Sea, because of the stealth of the Qianlong, it is impossible to find the Qianlong.

A few hours later, Qianlong entered the Sea of ​​Japan.

The Sea of ​​Japan, known as the Whale Sea in ancient times, is the largest marginal sea in the Northwest Pacific Ocean, with a sea area of ​​about 100 million square kilometers.The entire sea area is slightly oval 733 , with a length of 2300 kilometers from north to south, a width of 1300 kilometers from east to west, an average water depth of 1350 meters, a volume of 171.3 million cubic kilometers, and a maximum depth of 3742 meters.

It can be said that the Sea of ​​Japan is a real deep sea. Compared with inland seas such as the Yellow Sea and the Bohai Sea, it is much higher in terms of depth and drainage area.

Although this is called the Sea of ​​Japan, not all of this sea area belongs to Little Japan, and there are many areas on the high seas.

"Buzz...huhuhu..."

After entering the Sea of ​​Japan, Xie Qian immediately became more nervous, while Li Yunlong patted Xie Qian and said, "Don't be nervous, fight only when you reach the combat position!"

"Yes!" After hearing this, Xie Qian turned to the messenger next to him and said, "Order all members to maintain the highest vigilance and be ready to fight at any time!"

"Yes!"

The order was conveyed quickly!

This is the first time that a warship has stepped out of its own waters in the vast Chinese mainland!

Chapter 904 Where is the bombing?Nagasaki! (First update, please subscribe)

This time the Qianlong entered the Sea of ​​Japan, which was the first time for a warship from the vast Chinese mainland to leave its own sea area and enter the borders of other countries.

Not long after entering the Sea of ​​Japan, this is the sea area of ​​​​the island country, and the number of Japanese coastal defense warships began to increase.

This is why Xie Qian, the captain of Qianlong, is nervous.

The Qianlong's bombing of the mainland of the island country is a solitary operation. Without the air power cover of other warships of the Iron Blood Navy and the Iron Blood Air Force, it is completely alone. Therefore, once it is discovered, it will definitely be chased and intercepted!

The sea area of ​​the Sea of ​​Japan is very large, and at the same time the depth is very deep. The speed of Qianlong sailing in this sea area is still at a high speed.

Li Yunlong, Xie Qian and others stood in front of the control screen of the command cabin, watching the red dots flashing continuously on the radar screen. These red dots represented the warships of the Japanese army.

"The coastal defense forces of the Japanese army are still very strong. Fortunately, they did not choose to let the entire iron-blooded navy attack the island country!" Li Yunlong said slowly.

Now the Jagged Navy is in a state of rapid development, but encountering the long-developed and experienced Japanese navy is still not enough to destroy the entire Japanese navy. After all, the Japanese navy has many aircraft carrier fleet battle groups.

"Yeah, that's why we are dangerous!" Xie Qian was still in a state of high tension.

Xu Yihang looked at the radar screen, then looked at the situation map of the entire sea, and then looked at Li Yunlong and asked: "Brother Li, which city are we going to bomb the little devil?"

"Nagasaki!" Li Yunlong smiled faintly.

Nagasaki is a famous port city on the west coast of Kyushu Island and the capital of Nagasaki County.Located at the western end of Japan, only 800 kilometers away from Shanghai, it is a transportation hub city.

Li Yunlong talked about this city with a faint smile because, according to the course of history, the U.S. military will carry out atomic bombing on Nagasaki, but now the U.S. atomic bomb has not been developed yet, so he came to bomb first .

According to the process of history, at 1945:8 am on August 9, 11, following the atomic bomb attack on Hiroshima, the US military carried out the second atomic bomb attack on Japan.Drop the atomic bomb "Fat Man" on the center of Nagasaki.

The "fat" atomic bomb is a plutonium bomb with a length of about 3.6 meters, a diameter of 1.5 meters, a weight of about 4.9 tons, a TNT equivalent of 2.2 tons, and a blast height of 503 meters.

This time, the U.S. atomic bombing caused more than 23 casualties and missing people out of a population of 10 in Nagasaki City. 60% of the buildings in the city were destroyed, and many people died on the spot. A week after the bombing, thousands of people were still killed. Burned to death, the last survivors suffered from the after effects of radiation such as cancer, leukemia and skin burns.

It can be seen how terrifying the power of the atomic bomb is!

Although Li Yunlong has mastered the method of making atomic bombs, he has not yet discovered uranium ore, the most critical raw material for making atomic bombs, and he still needs to build factories for atomic bombs, reactors, etc... all of which cost a lot of money, material and manpower.

And even if the construction of the atomic bomb is completed, it must be able to drop the atomic bomb on the island country.

With the continuous development of the Jagged Lion Army, Li Yunlong believes that he will soon be able to manufacture an atomic bomb and carry out a nuclear strike.

Li Yunlong chose to bomb Nagasaki. A very important reason is that the city of Nagasaki is a port city near the sea, so it is very easy to attack!
