Jiang Gan flipped through the ledger again and smiled: "The cyber war is coming!" On June 18, Global Network News "U.S. Cyber Command Authorized to Preemptively Prevent Hacker Attacks"...... The Pentagon has quietly authorized the U.S. Cyber Command to take a 'more aggressive approach' to protect the U.S. from cyberattacks, a shift that means the force has the power to conduct routine hacker raids on foreign networks. ”

Wang Qiang was surprised: "I wipe, still daily assault?" Is this a rhythm that can't be stopped every day? ”

Su Su smiled: "Maybe it will cause some trouble to China, but Japan, Europe, and Russia will be difficult." In fact, in addition to filing, China still has a super big move. ”

Wang Qiang was surprised: "What big move?" ”

Su Su smiled: "Cut the submarine fiber optic cable!" China has been playing Jiaolong deep submersibles for many years, challenging the limits of deep diving, which is to show scientific and technological strength and strategy. Perhaps the people who eat melons just thought that they had caught a few sea cucumbers at the bottom of the sea of thousands of meters and came up to play, and then a group of public officials kept scolding this as an image project. But the real connoisseur knows how powerful industrial technology and material technology this requires, and even sea cucumbers can be caught, not to mention cutting network cables - the network cables are gone, what kind of hacker troops are you playing? ”

Gan Ning smiled: "I like to talk about these high-tech things, Wang Qiang, do you know how difficult it is to build a deep submersible?" ”

Wang Qiang was surprised: "Anyway, my brother won't make it, let's hear it!" ”

"The ultimate depth of a conventional submarine is 300 meters, while a nuclear submarine can reach 6,700 meters," Gan Ning said. At 700 meters of water, no torpedo can attack them, so in the past, when the United States and the Soviet Union were in the Cold War, they were fighting to the limit, and there were even 900 meters, considering that the depth of the dive is the top secret, so the data that came out publicly should be shrunk, then it should be 1000 meters, if you want to dive 1000 meters, the requirements for special steel and titanium alloys, as well as welding technology are really the peak! ”

Wang Qiang frowned: "But the deep submersible can reach 10,000 meters!" ”

Gan Ning said: "Yes, at this depth, it is no longer possible to make the hull with conventional welding technology, and the water pressure in the deep sea will easily break the hull from the weld, so it can only be forged, that is, a whole piece of alloy steel is used to forge the shape of the hull!" This is not as simple as forging an iron pot in a blacksmith shop, it has to use a 10,000-ton forging press! This is a world-class national treasure! ”

Wang Qiang was stunned: "10,000 tons of forging press? This name is too ordinary, it doesn't have the domineering of a national treasure at all! ”

Jiang Gan said with a smile: "The United States has manufactured two 45,000-ton forging presses for the aviation industry in 1955 for Alcoa, and they have been used until now, which are the national treasure-level equipment of the American aviation industry, and almost all the titanium alloy frames of fighter jets in the United States are forged by these two machines." ”

Wang Qiang was shocked: "Won't it?" Decades have passed, and there has been no development at all? ”

Jiang Gan said with a smile: "The company that built these two machines has long since gone bankrupt, and the three major heavy machinery factories in the United States have also disappeared. The situation in the United States in the past few decades has been known to the lord. Then in 2011, in order to make the F35, the United States also spent money to refurbish these two heirlooms. ”

Gan Ning said with a smile: "Russia's is called an heirloom, Ukraine built two 75,000-ton forging presses for the Soviet Union in 1961, and then Russia inherited it to this day." The Russian deep-sea submersible nuclear submarine is so powerful because of these two national treasures. Then in 1976, France asked Ukraine to buy a 65,000-ton national treasure, and then the European Airbus company could protest with Boeing. ”

Wang Qiang understood in seconds: "Ukraine! Good friends of the Chinese! What about us, China? ”

Jiang Gan sighed with emotion: "After all, it is a national treasure-level machine, and it is not so easy to get." China is more tortuous, at first it was 20,000 tons of compensation from Japan, and then in 1973 Southwest Aluminum had 30,000 tons, which was the largest national treasure in Asia at that time, all the large components of China's aerospace, Taihang turbofan engines were handed over to Southwest Aluminum. Without this machine, there would be no Chinese aerospace. ”

Wang Qiang was really shocked: "I can't imagine that a machine has such an important role in the development of a civilization!" ”

Gan Ning sighed: "Aviation is a delicate work, not only to pursue the tonnage of national treasures, but also to be precise enough, the engine problem of China's aviation has not been solved, that is, the precision of national treasures is not enough." ”

Jiang Gan smiled: "So in 2004, China CITIC Heavy Industries built a 18,500-ton forging press, although the tonnage is small, but it is precise enough. Then in 2013, China's 80,000-ton die forging press was born, and China's aviation parts forging reached the world's top level! ”

Wang Qiang was stunned: "The top? What about the United States? ”

Gan Ning said with a smile: "It's all said, the United States only has 45,000 tons of national treasures, and one ton is one street, and China has thrown off four streets of American Airlines!" ”

Jiang Gan said with a smile: "It's not just 4 streets, there are 100,000 tons and 150,000 tons of national treasures behind China!" ”

Wang Qiang smiled: "I can't believe it!" Although my brother knows that the United States is in decline and industry is hollow, he still admits that the United States Air Force is the strongest and the United States has the largest fist, which is a bit ......"

Gan Ning sneered: "Really? Then let's kill it! Didn't we talk about the Darksaber drone yesterday? Let's continue to talk about it, although the current international standard for 6th generation aircraft has not yet come out, there is no doubt that the dark saber is the 6th generation machine! ”

Wang Qiang was shocked: "Isn't it?" We haven't built a few fifth-generation J20 machines, and the sixth-generation aircraft has come out? ”
