My German Empire

"Command, there is something to report to you." The ward door is quietly pushed away, and the departure of General Onester.

The General Ostei had just got up, and the President Roosevelt waved his hand. "What is it, let's talk, there is no need to hide hiding."

The deputy officials hesitate to walk before the bed, be careful. "Just New York Coast Guard sent news, an oil ship near the port of New York has exploded."

"What ?!" General Ostead stood up and accepted. "Is it a German submarine ?!"

The deputy official shook his head. "It can't be sure, there are many boats that come often, there is an explosion of an oil ship. Hey, there is a passenger ship's explosion of the oil boat, and it has not been spared. In addition to these two, there is no other thing."

"Don't want to think about the submarine of the German." Roosevelt coughed, coughing for a long time, slightly slow, one word. "General Onester, we want to teeth to teeth, immediately send our submarine force to Europe to fight."

"..." General Onester did not disappear.

If the United States is the earliest country, the United States is one of the best countries that put submarines into actual combat countries.

As early as the US independence war in 1776, the submarine boarded the war stage for the first time. The patriotic Jerre University Graduates Davit Bush Neil started to study the method of cracking on the British army with the support of General Washington. The famous "sea turtle" boat in the history of submarine is born.

The "sea turtle" is like a turtle, and the boat air is allowed to breathe for half an hour; 2 ventilation in the upper part of the boat, the upper float is opened, and the down is closed, so that fresh air can be supplemented. In order to control the upper and sinks of the submarine, there is a ballast, and the water cabinet is controlled by the hand pump. In order to cope with an emergency, there is a 90 kg of iron block in the boat, and the rigital moment is throwing off the iron block, and the submarine can be quickly upset. The movement of the "Sea Turtle" boat is controlled by two manpower-driven propelles in the horizontal and vertical direction. The weapon is a weapon of about 68 kilograms of explosive bags outside the boat. When attacking it in the enemy ship The outer casing. That is to look at the current eyes, this is also a very complete underwater weapon.

Unfortunately, the attack of the "Turtle" boat did not succeed. On September 7, 1776, the first submarine attack in history started, this attack was performed by Shangzla. Lee. He drove the "sea turtle" boat successfully divened the tail of the British Warship "Eagle", and the next job is to wear a hole in the enemy ship with a drill bit to secure the explosive package. However, the place where he drilled was just a metal plate. After half an hour, he still did not drill the enemy ship, but he had to return.

Although the "Sea Turtle" did not achieve the results, it unveiled the prelude of submarine. From then on the battlefield of human beings, the water has developed into the water, and the "sea turtle" has also won the same design principle as the modern submarine. The United States in the world "the first military submarine" has occupied a place in the history of world submarine.

The first submarine that obtained the exact results in military history is also a US submarine, Hanley submarine.

Its appearance is approximately "Dolphin Shape", the design of the cross-sectional view is an ellipse, the total length is about 12 meters, the boat body is 1.2 meters, and it is necessary to operate simultaneously by 8 people. It uses the hand-shaped transmission to drive the propeller, and then realize the submarine Dynamic driver.

As for the reduction of floating operations, it can achieve sinking because the valve opens the water into the cabin. When up float, you need to drain it through artificial handlet pumps to achieve upper float.

On the weapon equipped in the submarine, it is quite original, and the modernization of information is unable to compare it. The Hanley submarine uses the design concept of the flame thunder, and it will be installed a 6-meter "stick" in the submarine head, "stick" another more than 40 kilograms of explosive bags.

In the fierce strategies of the United States, the military confrontation in the sea is also quite strong. At 9 o'clock on the evening of February 17, 186, the Hanley submarine lurking underwater suddenly attacked the enemy "Haoda Tongnick", and he sinking him, creating the world history. Subsequently, the Hanley is mysterious, and it has been salvaged from the later generations in 2000.

After several simulation experiments, the experts have been concluded: this submarine is "sinking" by oneself. The long rod of the submarine is equipped with explosives is too short. The submarine distance explosion point is only 6 meters during the explosion. A dramatic impact wave heavy created a boat's internal organs, blood quickly filled with lungs, boatmen quickly died ...

The submarine created many records: the first submarine that achieved results; the first submarine for sinking the submarine; the first submarine ...

Starting from the "Shuquat" level in the service in 1921, the US submarine officially opened the tradition named by aquatic animals: "Fish" level, "one corner whale" level, "dolphin" level, "smelt whale", "rat dolphin" Level, "squid" level, "heavy teeth", "river", "horse fish" level ...

However, since a war, the US Navy's emphasis on the submarine has gradually declined. The construction of the submarine is also someone else. I also have some mentality, mainly regarding the scouts of the main fleet, called "fleet submarine" . Of course, in the vast Pacific Ocean, there is only one or two thousand tons of drainage, and the submarine of the oil-free diesel engine is really a very suitable reconnaissance platform.

At the beginning of December 1941, in early December 1941, the US Pacific Fleet was only 21 submarines in the US Pacific Fleet, and only 11 submarines were put into battle immediately. The Philippines The Asian fleet is only 23 large submarines and 6 S-class small submarines.

Then, the United States has built 77 cat sharks, as well as 128 Barbu-level and 29 of the Baru-level submarines based on the 128. Results The submarine has been made too fast. The US Navy has encountered a happiness of happiness: I can't think of so many names of marine life! So they had to find some marine biologists and fishermen to help the submarine.

Not long ago, the US Congress has developed the "Two Ocean Naval Act", and significantly expand the navy, and the submarine power has also been expanded.

The new generation of cat sharks class (small shark-level) submarine begins to lay keel, the North Atlantic fleet is a vintage submarine, what to go to thousands of kilometers to combat the European coastline?

It can face the eyes of Roosevelt full of expectations, and General Onester can only agree with the scalp. "Yes, I will prepare immediately."

Back to the Naval Department of the Pentagon, General Onester found the Lockewood of the Submarine commander of the Northern Atlantic Fleet.

Lockewood's colors always insisted on using the submarine as an independent combat force, but now I heard the General Onester to send the submarine to Europe to combat the head. "It's impossible, our current submarines have no ability."

Onester will seriously look at the army. "I am looking for you to listen to you too difficult or impossible, there is nothing to overcome in the world. The German can do it, we naturally do it. Give you a week, after a week, the submarine will be prepared. set sail."
