In addition to the large-scale construction of surface ships, the U.S. Navy has finally realized its huge war value for submarines. The German Navy relied on its large number of submarines to suddenly pull Britain, the largest maritime trade power, to the tenth position in the world. During World War I, Britain lost a huge amount of domestic merchant ship tonnage. If China had not exported advanced escort destroyers to Britain on a large scale, Britain would have been defeated and sued for peace long ago. Based on this, the U.S. Navy obtained several old submarines from the United Kingdom that China exported to the United Kingdom in the last century, and then studied them. In 2008, the first operational submarine built by the United States, the Alligator-class submarine, was successfully tested. Its displacement is 1,000 tons. The crew is equipped with a 3-inch deck gun, 2 field-caliber machine guns, a broken-caliber machine gun, and an old torpedo fired from a 1.5-mm torpedo tube. The maximum endurance knot on the water surface is 8 knots. , underwater, diesel, electric propulsion, double shaft, horsepower surface, 2 hp, underwater, diving depth Wumi, this type of boat is an improved version of the early US Navy "Puffer" class boat, with a larger displacement and more capacity. Carrying a few gallons of fuel, the range has also been improved, and the overall level is equivalent to the old level of the Royal Navy's submarine force. Considering the huge threat from the Chinese Navy's surface ships and submarines, the U.S. Department of the Navy approved the construction of this type of submarine. , and the continuous improvements during the construction process made each Alligator-class submarine basically different. By the time the last submarine was launched, the performance of the boat had reached the level of the Chinese Navy's submarines for many years. The United States wants to make rapid progress in submarines. As for the U.S. Army, it actively imitates the Chinese Royal Army and builds mechanized forces. After World War I, the U.S. Army still had a huge expenditure. It is forced to reduce its army. However, China's 40,000 standing army forces the United States to maintain at least 10,000 standing troops. This is unique in the history of the United States because its previous military policy has been very low-key and for the sake of development. Economically, the number of U.S. military personnel has always been less than 200,000. Such a low military expenditure has allowed the United States to expand rapidly. But now it is different, and the Americans have begun to fight for global hegemony. The huge losses not only did not make the Americans stop fighting for world hegemony, but instead aroused the warlike nature of mankind and continued on the road to fighting for hegemony. At this time, the U.S. Army and the Royal Navy were the same. As an imaginary enemy, it was copied on the basis of China's old Lynx main battle tank. However, China's tanks have many irreversible parts, making it difficult for the United States to imitate its key parts throughout the course of World War I. The United States has continued to use various excuses to obtain tank repair parts from China from the Allied Powers, and then brought them back to China for imitation. In February 2018, the first imitation Lynx main battle tank went through a series of tests and inspections. After the display, it was transported to the Savannah Proving Ground in Illinois and underwent a 3300-kilometer walking test. The U.S. Army was basically satisfied with its performance, but the vehicle also exposed some problems during the test, such as the vehicle mounted on the bottom. The exhaust pipe will increase the temperature of the engine room floor, which is not conducive to the long-term travel of the tank. In the later stages of World War I, the industrial capabilities of the Allied Powers were severely damaged. Britain and France had to ask China to provide parts and then assemble the tanks themselves because of the price of Chinese tanks. It was getting higher and higher, and the Allies couldn't bear it. Later, the British moved the assembly of the tank to the United States. In the following year, the foreign trade Lynx main battle tank assembled in the United States was successfully imitated by the US military, and then the territory and motivation of this type of tank were absorbed. technology, the United States developed its own tank. The technology of this tank was also shared with the United Kingdom. Therefore, it was named "main battle tank, with a total length of 40 meters, which is larger than the early field tanks modified by the United Kingdom." The main armament is 2 7mm Hotchkiss cannons on each side! Door, 7 762mm Hotchkiss machine guns. The gun is mounted on a mount. The gun base can be retracted during transportation to reduce the width. There are 3 machine guns mounted on large hemispherical gun mounts. Among them, one is located on the fixed turret of the tank and points to the rear, and the other two are on the side doors. The gun mounts of the three machine guns can all rotate and the shooting angle is large. The remaining 4 are mounted on fixed gun frames. There is one on each side of the driver's turret. The United States canceled the last two machine guns and installed muzzleloader and Browning machine guns. When the tank is assembled, a bracket composed of angle iron and steel bars is first installed, and then the steel plate is connected to the bracket. The thickness of the frontal protective steel plate is 6 to 6 mm, with the turret armor being the thickest. There are partitions inside the tank that separate the fighting compartment and the power compartment. There are two sliding doors on the partition that can enter the engine compartment from the fighting compartment. There is a ventilation fan installed on the right front side of the engine compartment, which can suck in 2 cubic meters of air per minute. The tank is driven by a 2-cylinder liquid-cooled gasoline engine. This engine was originally an aviation engine with an output power of 248 3 kilowatts at 400 rpm. The engine uses an electric starter, and there is a starter handle in the combat compartment. On production tanks, the original Vertex series carburetors were replaced by 6 companies lifeReplaced with new carburetor. There are three gasoline tanks inside the tank, each with a capacity of 3o3 liters. The fuel tank is located at the rear of the tank body, also separated from the engine compartment by a partition. The three fuel tanks use pneumatic mercury to press fuel into a small tank above the engine. Gravity is then used to deliver the gasoline to the engine. The tank has a total weight of 43 tons and a total of 28 pairs of road wheels. There are no shock absorption measures between the road wheels and the tank chassis. There is also a support wheel in the middle of the vehicle body specifically used to adjust the track angle. On a level road, the vehicle can travel approximately 8 kilometers per hour. The crew of this type of tank is only 8, namely the commander, driver, 2 gunners, 3 machine gunners and an on-board mechanic. The driver is located at the front of the tank, with his head close to the observation window and a total of three main operating levers. The two joysticks close to the driver are the fast and slow adjustment handles, and the two outer ones are the direction handles. There are also switches for the foot brake and electric starter. The commander's position is below the fixed turret. The commander's special tool box is in the fighting compartment. When observing, the commander must stand on the toolbox to reach the observation window on the fixed turret. Communication within the tank is accomplished via a throat microphone. The speaker consists of a transmitter and a receiver. The transmitter is a twist-shaped sound collector tied around the neck of the occupant with a strap. There is a control box located next to the driver's position. The commander can communicate with anyone in the vehicle via the seat-side controls. The emergence of this type of tank shocked the Chinese Army because this type of tank is enough to threaten the old Lynx main battle tank and will impact China's export share of this type of tank. China calls the U.S. Y-type tank a vertical tank, but its combat effectiveness is still not as powerful as the Panther main battle tank currently in service in the Royal Sixth Army of China. Although China is dismissive of the American jump tank, European countries believe that this type of tank can completely replace the old Lynx main battle tank that China exports to them for foreign trade. The most critical factor is that various countries believe that the Yiyi tank equipped with two main guns is more powerful than the Lynx tank with only one main gun. and. The American Overlook tank has stronger armor protection than the Lynx, but the price is only half of the Lynx tank. For the weak economies of various countries after the war, American tanks are obviously more reasonable. As a result, the U.S. Army became proud. The formal production of this type of tank began in July 2016 and officially rolled off the production line. On June 3, 2020, the tenth tank rolled off the production line. During the road test, the engine backfire problem of this type of tank was that the fuel ignited prematurely and ignited, causing frequent fires. Later, the carburetor was replaced to solve the problem. In the process of transporting these tanks by train, a section of the railway bed collapsed under the heavy pressure of the 3-ton tank, causing one tank to overturn. However, after the original tank entered service. World War I is over, so this type of tank can only be used as combat support for infantry. Due to its large size, the heavy tank gradually exposed its shortcomings and was inconvenient to transport. Countries around the world began to pursue high-light armored vehicles, and gradually turned to China's Lynx light main battle tank. The Americans were not willing to fail, because after all, the tank took a lot of effort to drive, so experiments on its improvement continued. In order to improve reliability, several exported vehicles were modified with air-cooled engines in 2006. There was a large air inlet on the left side of the vehicle body to provide sufficient cooling air to the engine. At the same time, the weight of the tank was reduced. It was finally successfully manufactured in 1998. The first American light tank, Ruiqiao can be regarded as a copy of China's old Lynx main battle tank, because except for the round turret, its appearance is similar to the Lynx tank of China's Northern Heavy Weapons Manufacturing Group. They once protested to the United States, claiming that the Americans had pirated their company's tank design. However, because of the cold war between China and the United States, the United States boldly began to imitate Chinese standard weapons on a large scale. Due to China's pressure, European countries have to give up purchasing American equipment. However, European countries have taken advantage of the overt and covert struggle between China and the United States to seek benefits. In order to contain the United States, China has to lower the prices of weapons and equipment exported to Europe, so that European countries can purchase large quantities of them. have obtained China's advanced weapons. As the U.S. military continues to imitate Chinese standard weapons on a large scale, diplomatic wars between China and the United States have come one after another, but the effect is not obvious. The United States seems to be ready for war with China. Later, when all countries were vigorously developing their economies, the United States semi-mechanized its 10,000-strong standing army in a short period of time. I believe that within a few years, the U.S. military will mechanize its military. At the same time, the Americans have worked hard on aircraft. The British Camel fighter, the Italian Dove fighter, and the Chinese Black Hawk fighter were comprehensively studied, and in 2006, they successfully produced and equipped China's Black Hawk subtype. Various means were used to squeeze Chinese airlines out of the United States. A typical example is the espionage case of Pa Nianlang. The U.S. government insisted that Chinese airlines were conducting reconnaissance and photography of strategic targets on U.S. soil in the air, and therefore expelled Chinese airlines from the United States.??'s China Airlines. In this regard, China is naturally very angry. However, the imperial government seems to have no interest in breaking out in a war with the United States. Because Zhang Yunfei still wanted to use the Second World War to completely bring down the European powers. At that time, I was in contact with the United States. If a fight breaks out with the United States at this time, the war between the two powerful countries will be very long and even have an unpredictable outcome. For a powerful country, the ability of its citizens to resist in war cannot be underestimated. China is not sure of defeating the United States, and the United States is not sure of winning the war. Both sides know that the conflict between the two powers will make European countries profit from it. Therefore, although they are at war with each other, they both maintain the final restraint and do not want to take the initiative to provoke a war. In this way, the world structure after World War I became a situation in which the League of Nations, dominated by China, competed with the United States. However, the League of Nations was nothing more than an empty shell. At this time, China rarely took care of the affairs of the League of Nations, leaving it completely to Britain and France, allowing Britain, France, Italy, and Turkey to spit on each other. For thousands of years, Finland and Sweden have had a dispute over land ownership in the ?land Islands. The League of Nations stopped the conflict, studied the situation and decided that the ?land Islands should belong to Finland. In the same year, Poland seized the former capital of the Republic of Lithuania, and the League of Nations took no action. In recent years, Germany and Poland also competed for land ownership in the industrial area of ??Upper Silesia. The League of Nations held a referendum. Attribute Upper Silesia and its people proportionately to both countries. In the sixth year of vomiting, Greece invaded Bulgaria due to a dispute. The League of Nations successfully ordered Greece to withdraw its troops. Then Greece and Tš¹rkiye broke out into war, and the League of Nations was unable to stop it because Turkey was a member of the council. That same year, an Italian general was murdered in Greece, and Italian dictator Mussolini invaded and occupied the Greek island of Corfo in retaliation. The League of Nations asked Greece to compensate Italy, and the compensation would be temporarily kept by the League of Nations. However, as a member of the League of Nations, Mussolini directly collected the compensation and claimed that he had escaped the detection of the League of Nations authorities. In 2001, Germany stopped paying France's war compensation in the "Beijing Contract", and France, together with Belgium, invaded and occupied the German industrial area Ruhr. Italy and Tš¹rkiye supported the German action, but Britain supported the French invasion in retaliation for the Allies. Gradually, the League of Nations lost its regulatory role. Whoever is stronger has the final say, and the League of Nations exists in name only. Meanwhile, countries are just busy recovering and hoping for a fight between China and the United States. So in fact. The post-war international landscape has become a situation in which China and the United States compete for hegemony. On March 2020, negotiations between China and the United States on the United States¡¯ imitation of Chinese weapons and equipment broke down, and the Cold War began.
