The USS George Washington, a ballistic missile nuclear submarine, successfully passed through the Palace Sea and sneaked into China's East China Sea. In the command room of the USS George Bisington nuclear submarine, the captain, Lieutenant Colonel Otz Raben, He measured it on the chart with a scale. It was still more than 800 kilometers away from Shanghai in China. He raised his head and rubbed his aching eyes, and put the scale in his hand on the chart on the small table in front of him. superior. Stretched. I secretly thought that if we launch a nuclear war with [China], we can carry out nuclear strikes on Shanghai and Nanjing of [China] here. Generally speaking, [China]'s anti-submarine net has many loopholes. [China] is not as powerful as imagined. He finally relaxed. Angry, he took out his handkerchief, wiped the sweat from his forehead, and looked at the photos of his family stuck on the bulkhead. He shook his head helplessly and said to himself: "Hey, I have been away from home for more than 10 days." [] As a country's ultimate strike weapon, nuclear submarines are more mysterious than other naval ships. Once they go to sea to perform missions, almost no one knows their exact location, and no one knows exactly the joys and sorrows of the sailors on board. Especially as the captain of a nuclear submarine, he is under greater pressure. "Nothing is trivial on a nuclear submarine!" Every detail must be reported to him. Even the "letters home" of the sailors on the ship must be filtered by him as the captain. , For nuclear submarines, any action is not routine, and you must be careful again and again. Any carelessness may lead to unimaginable serious consequences. "" Lieutenant Colonel Otzraben, I often feel that I am going crazy sometimes. On the nuclear submarine, what made him feel the most was the feeling of freedom of "being out there" after going to sea. Although the superior will give some general mission guidance before each departure, once the submarine enters the water, the captain has the right to make his own decisions based on the actual situation. "The ballistic missile nuclear submarine USS George Bissington, stopping and going, slowly and cautiously crossed the [Chinese] country between Okinawa and Miyako Island, running from the South Pacific to Australia and other countries, or across The more than 200 kilometers wide Miyako Strait, an important maritime channel from the Pacific to Central America, South America and other places, sneaks into the East China Sea of ??China. It thought it had broken through China's first island chain and penetrated deep into China's strategic hinterland. In fact, it has already reached the end of the world. The waters in the East China Sea from the coastline of China to the Okinawa Trough are very shallow. Most of the sea areas are only 55 to 100 meters deep. Unlike the South China Sea, most sea areas have a depth of more than 3,600 meters. The depth of 55 meters to 110 meters is really too shallow for submarine operations. Activities in the East China Sea are extremely challenging for all submarines. What's more, the ballistic missile nuclear submarine USS George Washington has been targeted by China's "God Eye" military reconnaissance satellite since it left its home port in the Gulf of Mexico. When passing through the Panama Canal in the Caribbean Sea, it appeared again in "In the footage of China's "God Eye" reconnaissance satellite," when it appeared again at Pearl Harbor in Hawaii, it attracted great attention from "China". The George Washington-class ballistic missile nuclear submarine is currently the only ballistic missile nuclear submarine in the United States that is on combat readiness duty and performs strategic patrol missions. It belongs to the 2nd Fleet of the U.S. Atlantic Fleet. The 2nd Fleet is the strategic reserve of the Atlantic Fleet. The U.S. Atlantic Fleet returns to the United States to read novels in peacetime. Please remember our website: 16k.Cn. It is led by the Secretary of the Navy and the Chief of Naval Operations. In wartime, it is under the command of the Commander of the U.S. Atlantic Theater Headquarters. This time the USS George Bissington ballistic missile nuclear submarine appeared in the North Pacific where the US Pacific Fleet Command is located in Hawaii. The purpose of this unusual cross-theater mobilization must be extraordinary. Generally speaking, "satellite tracking and reconnaissance of submarines tracks the wake of the submarine, but satellite tracking cannot continue to track or track all the time. In addition, submarines are relatively small and are limited targets. Most of them are between 1 meter and 152 meters in length." , and the submarine¡¯s diving depth, driving speed, seabed characteristics and water clarity will also have a certain impact on the satellite reconnaissance effect. This requires intelligence analysts to make judgments and find it in the next satellite image. Submarine wake, because the submarine wake is always continuous, its length can even extend for several kilometers. When Deng Feng received the intelligence analysis department of the Fourth Bureau of the Second Department of the General Staff, "About the USS George Washington ballistic missile nuclear submarine in Hawaii and in Ryukyu." East of the islands, after photos and analysis of submarine wakes. He felt that the United States kept sending conciliatory signals to [China] diplomatically, but the United States was still unwilling to peacefully resolve the South Korean missile crisis with [China], and wanted to compete with [China]. Fan, give it a try. The top brass of the Military Commission and the General Staff are more serious. They understand that the series of conciliatory signals sent by the United States in diplomacy are just a smokescreen before US imperialism launches a nuclear war. China must be fully prepared. . ?Deng Feng and Wang Kunpeng were not clear about the "real" intentions of the United States for a while. They must not take the nuclear threat or preparation for nuclear war from the United States lightly and must prepare for a nuclear counterattack. February On the 28th, Deng Feng issued an order to all fleets of the Chinese Navy to urgently dispatch all anti-submarine forces, strengthen vigilance in their patrol areas, and promptly report the discovery of U.S. submarines through the "Shenzhou 1" over the North Pacific. "Geostatic Military Communications Satellite" He issued a lock-on-target warning to the "Qianlong" class "No. 102" nuclear submarine of China's North Sea Fleet, which was on combat readiness duty in the waters east of the Hawaiian Islands in the North Pacific and carried strategic nuclear missiles. , the order to be ready at any time to carry out nuclear counterattacks against the United States mainland on the west coast of the United States. At the same time, the "Shenzhou 2" static-orbiting military communications satellite over the North Atlantic also transmitted the same order to the "Qianlong" class nuclear submarine of China's Indian Ocean Fleet that was on combat readiness duty in the North Atlantic. "No. 101" nuclear submarine. No. 101 is also ready to carry out strategic nuclear strikes on the U.S. mainland from the east coast of the United States at any time. The modified B52 nuclear strategic bomber is located at the Taiwan Air Force Base and the Ryukyu Islands. They are ready to carry nuclear bombs into the air at any time. Early warning aircraft of the Navy and Air Force are also on hourly combat readiness duty. "The US government knows nothing about this series of activities taken by China." "The USS George Washington" ballistic missile nuclear submarine thought it had successfully broken through the anti-submarine net of China's first island chain. Don't you know that the Chinese Navy has laid a dragnet for it, and the stern enemy will hunt it in the East China Sea. The Miyako Strait is the patrol area of ??the Ryukyu Detachment of China¡¯s East China Sea Fleet. When the "George Bissington" nuclear ballistic missile submarine was approaching the Miyako Strait in the North Pacific, the Ryukyu detachment had received a notice from the East China Sea Fleet to track the George Bissington-class ballistic missile nuclear submarine and pay close attention to its every move, but do not alarm it. It. If the house wants to pass through the Miyako Strait, let it in" and seal the door. According to the instructions of the fleet, the Ryukyu detachment made corresponding arrangements. And two "dolphin" submarines were ambushed in the Okinawa Trench at the western end of the Miyako Strait for the purpose of "closing the door". The USS George Washington nuclear submarine, 600 kilometers southeast of Shanghai and more than 200 miles east of Taizhou, was traveling slowly from south to north at a speed of 5 knots. They turned on the electronic system on the submarine and started their intelligence Collection work and familiarity with the underwater combat environment in the East China Sea. The aN/BQS-4 active sonar array is installed on the hemisphere of the USS George Washington ballistic missile submarine. It emits pulsed ultrasonic waves from time to time to "irradiate" the target, and then receives the echo reflected by the target in the water and performs calculations to determine the target. Parameters. Detect surrounding reefs, shipwrecks, sea depths, mines and hidden submarines with engines turned off; the aN/BQR-2B passive sonar array arranged at the bottom of the USS George Washington nuclear submarine is also quietly receiving various The radiation noise generated by passing ships and the signals emitted by hydroacoustic equipment are used to determine the target's position and collect information and intelligence data for the United States' future nuclear submarine counterattacks in this sea area. In the command room of the USS George Washington nuclear submarine, the captain, Lieutenant Colonel Otz Raben, carefully marked the route of his submarine and analyzed the situation in this sea area. He never expected that it was him. Around the "George Washington" nuclear submarine, the underwater killer "dolphin" known as the undersea black hole of the East China Sea Fleet of the Chinese People's Liberation Army has been moved unnoticed and quietly. They silently surrounded it. They did not detect the Chinese "Dolphin" class submarines that were surrounded from all sides in time. This cannot be said to be that the sonar soldiers on the "George Washington" ballistic missile nuclear submarine were not strong enough. . In fact, due to the technical limitations of the time and the backwardness of submarine design, the location of the sonar system installed on the USS George Washington strategic missile nuclear submarine was far behind that of "Chinese" submarines, let alone submarines. There are other functional deficiencies in the detection methods themselves. The main position of the sonar system of the USS George Washington ballistic missile submarine is to install the aN/BQS-4 active sonar array on the upper part of the hemispherical submarine and the aN/BQS-2B passive sonar array under the submarine. In addition, the range of sonar in the United States is limited, only a few kilometers. The detection effect of sonar must be poor. Unlike [Chinese] submarines, in addition to being equipped with medium-frequency active and passive search and attack hull sonar on the bow of the submarine, and passive low-frequency search sonar arrays on the side. Using the same signal received at different locations and at different frequencies, after computer processing and calculation, enemy ships can be quickly located. This is extremely beneficial for submarines, because the longer the baseline for measurement, the higher the accuracy. In addition, the "dolphins" of ChinaThe submarine is also equipped with photoelectric detection systems including television cameras, infrared imagers and laser range finders. The electronic system also includes a four-band planar search radar and radar warning system. The boat is equipped with China's domestic digital and automated combat command system. All detection systems and weapon systems are integrated. The combat command system is fully functional, has a high degree of automation, and has a fast response speed. It has strong search and tracking capabilities. In this era, it is completely possible to make early detection and strike first. In addition, [China] The "Dolphin" submarine is called "the quietest submarine in the world today." The concealment of the submarine is determined by the quietness of the submarine itself. The quietness of the submarine mainly depends on the low noise of the submarine. Keep your actions concealed to avoid being discovered by enemy sonar, and you can also increase the detection range of your own sonar to detect the enemy first and maintain the initiative in combat. The "Dolphin" class adopts a smooth teardrop-shaped linear hull and a stubby appearance. , is the best noise reduction form after precise calculation by the Central Design Bureau of Ruby Marine Machinery of the later Soviet Union. Its propeller is a 7-blade large side-inclined propeller. The speed is reduced to 250 rpm: the diesel engine is placed on a soft cushion. Operation: All noise-generating equipment on the entire boat is under closed management; the submarine's shell is also embedded with plastic silencing tiles, which not only absorbs the noise of the submarine itself, but also attenuates the noise of the other party's active sonar. Please remember our website: 16k .Cn sound wave reflection. The noise of the "Dolphin" class submarine is only 120 decibels, which is 2 decibels higher than the later Soviet Union's Kilo-class 636, so it won the title of "Oceanic Black Hole". Practice has proven that "every 6 decibels of submarine underwater noise reduction can reduce the detection distance of enemy submarines' passive sonar by half. Once the submarine's own noise drops to 90 decibels, the ocean background noise can completely cover up the submarine's whereabouts. Anechoic tiles It can also reduce the intensity of the echo, which directly affects the range of the sonar. Especially when facing the bow direction of the submarine, the echo may be submerged in the reverberation. The acoustic performance of the submarine anechoic tile changes with frequency. The frequency band noise reduction effect is poor. The most effective way to deal with submarine anechoic tiles is to further reduce the low frequencies of the sonar. Of course, the problem is not that simple. Because this also requires solving a series of new technical problems caused by lowering the frequency. In this day and age, it is absolutely impossible for the old Americans to do that. Even they don't know what anechoic tiles are. Not to mention an effective way to deal with submarine silencer tiles. As the United States, which has always sought world hegemony and regards China as the main threat and wants to suppress the rise of China, this time it secretly sneaked a strategic nuclear submarine into the East China Sea. Deng Feng felt very angry, regardless of Whatever the motivations of the United States are, it is a serious challenge to China's core interests. The China at this time is a strong and proud country under the leadership of the MZD, but it is not the East Asian country before 1949. The old "China", where sick men are bullied at will, is not a "China" with the characteristics of "hiding its strength and biding its time" and not even daring to say a harsh word. How can we tolerate the United States' intensified and rampant provocations on its own doorstep? Core interests zhUZhudao.com
