"George. The USS Washington ballistic missile submarine passed through the Miyako Strait and dived into the waters of the East China Sea. In the command room of the USS Washington nuclear submarine, the captain of the submarine Lieutenant Commander Ozraben measured the chart with a scale, which is still more than 800 kilometers away from Shanghai, China, and he raised his head and rubbed his somewhat astringent eyes, and put the scale in his hand on the chart on the small table in front of him. Stretched. I thought to myself that if we started a nuclear war with China, we would be able to carry out nuclear strikes on China's Shanghai and Nanjing. In general, China's anti-submarine net, there are many loopholes, China is not as strong as imagined, he finally breathed a sigh of relief, he took out a handkerchief, wiped a layer of sweat oozing from his forehead, and looked at the photos of his family stuck to the bulkhead. He shook his head a little helplessly, and said to himself: "Hey, I've been away from home for more than 10 days." ”

As a nation's ultimate strike weapon, nuclear submarines are more enigmatic than other naval vessels. Once out on a mission, almost no one knows exactly where they are, and no one knows exactly what the sailors on board are happy and sad about. Especially as the captain of a nuclear submarine, the pressure is even greater, "There is no trivial matter on a nuclear submarine!" For nuclear submarines, any action is not routine, and we must be careful and careful, and any carelessness may lead to unimaginable serious consequences.

Lieutenant Colonel Otzraben often feels like he's going crazy sometimes. On the nuclear submarine, what he feels most is to enjoy the feeling of freedom after going to sea. Although the boss will give some general mission guidance before each departure, as soon as the submarine is in the water, the captain has the right to make his own decisions according to the actual situation.

"George. The USS Washington ballistic missile nuclear submarine slowly and cautiously crossed the Miyako Strait, an important sea route between China's Okinawa Island and Miyako Island, which runs from the South Pacific Ocean to Australia and other countries, or across the Pacific Ocean to Central America and South America, and dived into the waters of China's East China Sea. It thought it had broken through China's first island chain out of nowhere, penetrating deep into China's strategic hinterland. In fact, it has already entered the Jedi, and the waters between the East China Sea and the coastline of China and the Okinawa Trough are very shallow, with most of the sea depth only 55-110 meters. No, unlike in the South China Sea, most of the sea is above 3,600 meters deep. The depth of 55 meters to 110 meters is really shallow for submarine operations, and activities in the East China Sea are extremely challenging for all submariners.

Not to mention George. The USS Washington ballistic missile submarine was targeted by China's "Divine Eye" military reconnaissance satellite from the moment it left its home port in the Gulf of Mexico. When the Caribbean Sea passed through the Panama Canal, it once again appeared in the footage of China's "God Eye" reconnaissance satellite, and when it reappeared at Pearl Harbor in Hawaii, it attracted great attention from the Chinese side.

George. Washington-class ballistic missile nuclear submarines, the only ballistic missile nuclear submarine in the United States that is on combat readiness duty and carrying out strategic patrol missions. It is subordinate to the 2nd Fleet of the US Atlantic Fleet, which is the strategic reserve of the Atlantic Fleet. The US Atlantic Fleet is under the leadership of the US Secretary of the Navy and the Chief of Naval Operations in peacetime, and is under the command of the commander of the US Atlantic Theater Headquarters in wartime. This time George. The USS Washington ballistic missile submarine appeared in the North Pacific at the headquarters of the US Pacific Fleet in Hawaii, and this unusual move across the theater of operations was certainly extraordinary.

Generally speaking, satellite tracking and reconnaissance of submarines is to track the submarine wake, but satellite tracking cannot be continuous or constant tracking. In addition, submarines are relatively small and are limited targets, with a length of between 91 and 152 meters. This requires intelligence analysts to find the submarine wake in the next satellite image, based on judgment, because the submarine wake has always been continuous, and its length can even extend several kilometers.

When Deng Feng received a letter from the intelligence analysis department of the Second Department and the Fourth Bureau of the General Staff Department, about the United States George . USS Washington ballistic missile nuclear submarine in Hawaii and east of the Ryukyu Islands, after a photo of the submarine wake as well as analysis of the data. He felt that the United States has been sending diplomatic signals of reconciliation to China, but the United States is still not willing to settle the issue of the South Korean missile crisis peacefully with China in this way, and it will have to compete with China and try it out.

The high-level leaders of the Central Military Commission and the General Staff Department have a more serious understanding, and they understand that the series of diplomatic signals of reconciliation sent by the United States are only a smokescreen before US imperialism launches a nuclear war, and China must be fully prepared.

Deng Feng and Wang Kunpeng could not figure out for a moment what the real intentions of the United States were, and they absolutely could not take lightly such a nuclear threat or preparations for nuclear war by the United States, and they must make preparations for a nuclear counterattack.

On 28 February, Deng Feng issued an order to all fleets of the Chinese Navy to urgently dispatch all antisubmarine units to strengthen vigilance in their patrol areas and report to US submarines in a timely manner.

Through the "Shenzhou-1" stationary military communications satellite over the North Pacific, he issued an order to the "Qianlong"-class "No. 102" nuclear submarine of the Chinese North Sea Fleet, which is on combat readiness duty in the waters east of the Hawaiian Islands in the North Pacific Ocean and carrying strategic nuclear missile bombs, to lock on to the set target and be ready to launch a nuclear counterattack on the US mainland on the west coast of the United States at any time.

At the same time, the "Shenzhou-2" stationary military communications satellite over the North Atlantic also transmitted the same order to the "Qianlong"-class nuclear submarine "Project 101" of the Chinese Indian Ocean Fleet, which is on combat readiness duty in the North Atlantic. The 101 is also ready to launch a strategic nuclear strike on the continental United States from the east coast of the United States in the Atlantic Ocean.

The modified B52 nuclear strategic bomber, which is located at the Taiwan and Ryukyu Islands air bases, is also ready to carry nuclear bombs into the air at any time.

AWACS aircraft of the Navy and Air Force also took to the skies for 24-hour combat readiness.

The U.S. political axe is ignorant of this series of activities that China has undertaken.

"George. The USS Washington ballistic missile submarine thought it had succeeded in breaking through the anti-submarine network of China's first island chain. Do you not know that the Chinese navy has laid a net against it, and is ready to hunt it down in the East China Sea.

The Miyako Strait is the patrol area of the Ryukyu detachment of the East China Sea Fleet. "George. USS Washington" ballistic missile nuclear submarine, in the North Pacific near the Miyako Strait, the Ryukyu detachment has been notified by the East China Sea Fleet to track George. Washington-class SSBN, keep an eye on its every move, but don't alarm it. If it's going through the Miyako Strait, let it in, and seal the door. In accordance with the instructions of the fleet, the Ryukyu detachment made corresponding arrangements. He also ambushed two "Dolphin" submarines in the Okinawa Trench at the western end of the Miyako Strait for the purpose of "closing the door."

600 kilometers southeast of Shanghai and more than 200 miles east of Taizhou, the American "George. The USS Washington was traveling slowly from south to north at a speed of 5 knots, and they turned on the electronic systems on the submarine to begin their intelligence-gathering work and familiarize themselves with the underwater combat environment in the East China Sea.

Set in George. The USS Washington ballistic missile submarine has an AN/BQS-4 active sonar base array in the hemispherical shape, which from time to time shoots pulsed ultrasonic waves to "irradiate" the target, and then receives the echo reflected by the target in the water and calculates to determine the target's parameters. Detect surrounding reefs, shipwrecks, sea depths, mines, and hidden submarines with engines turned off; Arranged in George. The AN/BQR-2B passive sonar base array in the lower part of the USS Washington is also quietly receiving the radiated noise generated by various passing ships and the signals emitted by underwater acoustic equipment to determine the direction of the target. Collecting information and intelligence materials on [***] ships and submarines. Gather first-hand intelligence for future U.S. nuclear and submarine counterattacks in this area.

"George. In the command room of the USS Washington nuclear submarine, the captain of the submarine Lieutenant Commander Ozraben carefully marked the route of his submarine and analyzed the situation in this sea area. He never imagined that it would be in his "George. Around the USS Washington nuclear submarine, four drop-type diesel engine submarines of the East China Sea Fleet of the Chinese People's Liberation Army, known as the underwater killer "Dolphin" submarine of the seabed, are unknowingly and silently surrounding it.

The Chinese "Dolphin" class submarine surrounded by four sides was not discovered in time. The sonar crews on the USS Washington ballistic missile nuclear submarine are not very skilled. It was really limited by the technology of the time and the backwardness of submarine design. The position of the sonar system installed on the USS Washington strategic missile submarine is far behind that of China's submarines, not to mention the functional defects of the submarine itself in other aspects of its detection means.

"George. The main position of the sonar system of the USS Washington ballistic missile nuclear submarine is the installation of an AN/BQS-4 active sonar base array in the upper part of the submarine's hemispherical shape and an AN/BQR-2B passive sonar base array under the submarine. In addition, the sonar of the United States has a limited range of only a few kilometers. The detection effect of sonar is definitely poor.

Unlike Chinese submarines, except for the bow of the submarine, it is equipped with an active and passive search and attack hull sonar and a passive low-frequency search sonar base array on the side of the submarine. Using the same signal received at different positions and frequencies, after computer processing and calculation, the enemy ship can be quickly located, which is extremely advantageous for submarines, because the longer the measurement baseline, the higher the accuracy.

In addition, China's "Dolphin" submarine is also equipped with a photoelectric detection system, including a television camera, an infrared imager, and a laser rangefinder. The electronic system also includes an i-band plane search radar and a radar warning system. The boat is equipped with a Chinese-made 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, fast reaction speed, and strong search and tracking capabilities.

In addition, the Chinese submarine "Dolphin" is called "the quietest submarine in the world today." The concealment of the submarine is determined by the quietness of the submarine itself, which mainly depends on the amount of noise of the submarine. The noise of naval battle submarines is low. This will not only keep the action concealed and avoid being discovered by the enemy's sonar, but will also increase the detection distance of its own sonar, so that it can be discovered by the enemy before it is discovered, and the initiative in combat can be maintained.

With its smooth pear-shaped linear hull and short and thick appearance, the "Dolphin" class is the best form of noise reduction that has been carefully calculated by the Central Design Bureau of Ruby Marine Machinery of the Soviet Union. Its propeller is a 7-blade large-side inclined propeller, and the speed is reduced to 250 revolutions per minute; The diesel engine is run on soft pads; And all the noisy equipment of the whole boat is closed management; The hull of the submarine is also embedded with plastic silencing tiles, which can not only absorb the noise of the submarine itself, but also attenuate the sound wave reflection of the opponent's active sonar.

The noise of the "Dolphin" class submarine is only 120 decibels, which is slightly higher than that of the later Soviet Kilo-class Type 636, so it received the title of "oceanic black hole". Practice has proved that every 6 decibels reduction in submarine underwater noise can reduce the detection range of enemy submarine passive sonar by half, and once the submarine's own noise is reduced to 90 decibels, then the ocean background noise can completely cover the submarine's whereabouts.

Anechoic tiles can also reduce the intensity of the echo, which directly affects the distance of sonar. Especially when facing the bow direction of the submarine, its echo may be drowned in reverberation. The acoustic surname of the submarine anechoic tile can change with frequency, and the silocating effect is poor in the low frequency band. The most effective way to deal with submarine silic tiles is to further reduce the low frequencies of the sonar. Of course, the problem is not that simple. This is because it also requires solving a new set of technical problems that come with reducing the frequency. In this era, Lao Mei will never be able to do it. They don't even know what the silencing tile is. Not to mention the effective way to solve the problem of coping with submarine silencing tiles.

As the United States, which has always sought world hegemony and regards China as a major threat, and wants to suppress China's rise, this time it sneaked its strategic nuclear submarine into the East China Sea. Deng Feng felt very angry, no matter what the motives of the United States are, it is a serious challenge to China's core interests. At this time, China was a China under the leadership of MZD, with a strong iron backbone and a proud China. But it is not the old China before 1949 when the sick man of East Asia was bullied at will, nor is it the characteristic China that "Taoguang Yanghui" did not even dare to say a hard word. How can we tolerate the United States so aggressively and rampantly provoking China's core interests at its own doorstep?
