Chapter 577: Anti-Submarine

Just as Yannick put down the phone, Reinhard walked in hurriedly. "Your Highness, this is a photo that was just faxed from Washington. People in Washington stormed the White House, and the White House was on fire." He handed over three A4 papers.

The fax machine is nothing new. Its history predates the telephone and is not much later than the telegraph machine.

As early as 1843, before Morse's first telegraph line was set up, Scottish electrical engineer Alexander Bain invented the first fax machine, which used an electromagnetic excitation pendulum for scanning, with a fax machine mounted on the top of the pendulum. There is an electric brush that swings back and forth through the pendulum to scan the words written in metal on the transmitting platform. When receiving, the metal brush is scanned on the paper soaked in starch solution, and a colored record is produced through a chemical reaction.

In 1848, Bakewell further developed Bain's fax technology. His most outstanding contribution was the invention of barrel scanning technology, which was still used in later generations.

By 1925, American Telegraph and Telephone Company's Bell Labs developed a practical fax machine using vacuum tube technology and photoelectric tube technology, and the next year it launched a wired photo fax service across the American continent. In August 1945, at the Potsdam Conference, color photos of Stalin, Truman, and Attlee were sent to Washington via fax machine via radio.

It's just that the current fax technology is lacking in transmission efficiency and clarity. It takes more than 20 minutes to transmit one page of A4 format documents, and it took more than an hour to transmit these three pictures. Moreover, the photos taken by today's cameras are far less clear than those of later generations of high-definition digital cameras. Problems such as distortion occur during transmission, and the effect is even worse. It reminds people of the inferior prints on street stalls in later generations.

But Yannick still watched with gusto. "Haha, the White House was burned down again?"

Why do you say it again? The White House was burned once as early as 1814.

In 1812, with the ambition of liberating the Canadian people, the United States attacked the Canadian provinces of the British North American colonies. Militiamen across Canada actively participated in the war to meet the US military. The United States and Britain had victors and defeats on the battlefield, and the Canadian militia was brave in combat. In 1814, after Britain defeated Napoleon in Europe, it was able to free up more energy for the North American battlefield. In 1814, the British army occupied the state of Maine in the United States. In the same year, the British army and Canadian militia invaded Washington, the capital of the United States. The then US President James Madison was forced to flee to Virginia.

In retaliation for the U.S. military's burning of York City (today's Toronto, Canada) in 1813, British troops and Canadian militiamen looted U.S. government supplies and burned public buildings in Washington, the U.S. capital. The president's residence, the White House, was also burned down.

The war was the first, and so far only, time in which the nation's capital was occupied by foreign troops and the White House was set on fire. In 1815, the United States and Britain signed the Treaty of Ghent, and the borders were restored to their pre-war status without any territorial concessions from either side. After the war, in order to cover up the traces of the burning of the presidential palace, the Americans painted it with white paint, which is why today's "White House" was created.

It's a good thing now that their foreign enemies haven't even set foot in the United States yet, but the White House has been burned down by their own people. It's really interesting. "Unfortunately, the fire is a little smaller." Looking at the location of the fire, someone must have thrown a Molotov cocktail? “Give this to Goebbels and ask him to give it a nicer name, like ‘The Fire of Freedom Burns America’ or something like that.”

Reinhard had just left when Redl from the Admiralty called. "Your Highness, a patrol plane discovered a submarine in the H2 waters, and it is suspected to be an American submarine."

"Oh? Do the Americans want to fight tooth for tooth, eye for eye?" Yannick couldn't help but sneered. Germany's Tiger Shark submarine is at home near the U.S. coastline, causing chaos in the shipping lanes and panic among people. It seems that the Americans can't sit still anymore and have sent submarines to harass them?

But you don’t even look at what kind of submarines you have. You still want to jump around with a submarine that doesn’t even have a ventilator? "There is no need to report this kind of thing from now on, we will sink each one we see!"

It seems that this S-54 submarine is also unlucky. There is a fleet sailing more than 200 kilometers away from here. After receiving the order, the escort aircraft carrier immediately took off several anti-submarine aircraft and went to the H2 area where the submarine was discovered, and the patrol aircraft Convergence.

"The submarine dived immediately after it was discovered. More than 30 minutes have passed."

"That is to say, it is within a radius of ten kilometers." A radius of ten kilometers can be said to be big or small. "Get that bastard out."

Several anti-submarine aircraft used this as the center point and began to hover at low altitude, and one anti-submarine bomb after another fell into the sea. This kind of anti-submarine bomb is modified from an aerial bomb. The small aerial bombs that are about to be eliminated are slightly improved and equipped with a proximity fuze to become a new anti-submarine bomb.

It is much more practical than traditional depth charges. For example, depth charges will make special sounds when they enter the water and sink, which can be easily distinguished by submarine sonar operators, which gives the submarine time to give an early warning.

Because it uses a proximity fuse, there is no need to know the exact depth of the submarine; this is quite a headache with depth bombs. The submarine is also constantly maneuvering vertically, and the error in determining the depth of the initial depth bomb is relatively large. of.

"boom!"

An anti-submarine bomb fell near the fleeing S-54 submarine and exploded.

"Wright, why didn't you issue a depth charge warning?!" S-54 Captain Taylor reprimanded the sonar operator and looked in the direction of the explosion. He felt that the explosion was very close. Logically, at this distance, the power of the depth charge should at least be able to shake them all over the place. Why is the German depth charge so weak?

The sonar operator said innocently. "Captain, I didn't hear the sound of the depth charge entering the water."

Taylor didn't bother to pay attention to the sonar operator. His intuition told him that it was dangerous to stay at this depth. "Keep diving!" Following his order, the propeller at the tail of the submarine slowly turned, the hull slowly tilted, and the front end moved towards the deeper sea. "Dive to a depth of 70 meters."

"70 meters?" The people around were shocked, and the helmsman in charge of the operation even turned his head and asked. "Captain, are you sure you want to dive to a depth of 70 meters?" The safe diving depth of their S-class submarines is 200 feet, which is 96 meters. Now the captain wants to dive to 70 meters? You have to know that the seawater has an amazing pressure. For every 10 meters of depth increase, the pressure will increase by 0.3×105Pa (slightly higher than 1 standard atmospheric pressure). Now that it has exceeded the safe diving depth, who knows what will happen.

"Execute the order!" Taylor nodded confidently. Because he knew that the maximum diving depth of this submarine was 85 meters, and the so-called safe diving depth had a margin, so even if it dived to a depth of 70 meters, it would not be crushed by the seawater.
