After coming out of Jinghua University, Chen Hao came to the small clinic non-stop, called Qian Long and went straight to the Yellow Sea, because Chen Hao had already received news from Qianqian that the anti-submarine exercise of the United Fleet was about to start tonight. Chen Hao plans to muddy the waters again and make this combined fleet look like an ocean.

Nedwood sat in the large swivel chair in the captain's room, his eyes closed, recuperating. This time the Combined Fleet did not go well as soon as it departed from the Wa Kingdom, and his sixth sense told him that something big would definitely happen this time, and Nedwood had always been proud of his super strong premonition.

It was because of his super premonition that Nedwood avoided two fatal car accidents. However, the Ministry of Defense did not agree with the proposal to cancel the exercises on its own. Although I was uneasy, I thought that the country that dared to challenge the powerful aircraft carrier fleet of the United States had not yet been born, so I was relieved to boldly go out of the port.

But what annoyed him was that the great American fleet lost two AWACS planes on the first day, although one was crashed due to mechanical failure, and the other was injured by friendly soldiers, and it seemed that there was nothing abnormal, but Nedwood still faintly felt that some conspiracy was approaching him.

The incident in which his own missile destroyer fired all the shells that hit the Aegis destroyer of the Japanese Kingdom (it was this warship that fired missiles and mistakenly hit the AWACS aircraft) was also full of strangeness, which further aggravated Nedwood's uneasiness. Many officers and men of the Japanese fleet secretly accused the U.S. fleet of deliberately retaliating, resulting in the death of nine people, including the chief officer and staff officer, and the wounding of 27 on board the destroyer Asagiri.

The people of the United States are dumb, and they can't say that they have bitterness when they eat Coptis chinensis. The Phalanx system is automatically controlled by a high-speed computer on a warship, and the people of the United States can't command the Phalanx system if they want to retaliate, unless the computer program is changed.

But this reason did not satisfy the officers and men of the Japanese state, and Nedwood found that the rift between the United States and the Japanese fleet was slowly growing, which was extremely dangerous for a combined fleet.

He once proposed to the Department of Defense to terminate the exercise, but the Department of Defense refused, and Nedwood had no choice but to continue to command the entire Combined Fleet to continue the following exercise according to the exercise plan.

After a thorough inspection of the weapons system, the exercise resumed on Friday, and Nedwood had been nervously standing on the bridge, watching everything with his binoculars. Fortunately, the following landing maneuvers went smoothly and there were no more accidents, which completely relaxed the nerves that had been tense for two days.

Hearing the news that everything was okay from the staff officer next to him, Nedwood raised his hand and snapped his fingers, and the beautiful blonde girl next to him immediately walked over. "General, what do you need?"

"A cup of coffee, thank you."

Taking the steaming coffee, Nedwood took a sip. There must not be any mistakes in the anti-submarine exercise that began tonight, and Nedwood secretly prayed in his heart that as soon as the anti-submarine exercise was over, he would return to the base as soon as the anti-submarine exercise was over, so as not to have too many dreams at night.

However, suddenly the "beep" alarm sounded, Nedwood's hand shook, and most of the coffee spilled, and the blonde girl on the side immediately scrambled to wipe the brown coffee stains on Nedwood's white shirt, but Nedwood pushed her away and asked loudly, "What's the matter?" ”

"It was discovered that a submarine of unknown nationality had entered our anti-submarine encirclement and was heading at low speed towards our aircraft carrier USS Washington."

"Report its position, course, speed and depth, judge the submarine type and nationality." Nedwood looked a little excited, the original anti-submarine exercise was to use one conventionally powered submarine from the Japanese country and one from the United States as an imaginary enemy, but now he didn't expect a prey to come to the door. The sheep who took the initiative to enter the wolf pen did not play with it, and seemed to be a little sorry for it.

"The target course is 011, the speed is 3 knots, the depth is 150 meters, and it is 4.8 nautical miles from our ship." The sonar soldier reported loudly.

"What!" Nedwood suddenly changed color, stood up abruptly and scolded: "Bastard, what the hell are you eating, you actually let the enemy slip under your nose, order all anti-submarine ships to turn on active sonar, go all out to detect the position of the submarine and prepare for an anti-submarine torpedo attack, invent a telegram, let it report its nationality, and quickly surface, otherwise it will be attacked." ”

Modern submarines carry anti-ship missiles with a range of about 40 kilometers. The submarine is only 4.8 nautical miles away from itself, that is, less than 9 kilometers, and it only takes 33 seconds for an anti-ship missile to hit itself once it is launched, and such a small reaction time is simply impossible to effectively intercept.

I thought that a good prey had come, but I didn't expect that I became the prey of the enemy, if the submarine fired missiles at itself, then most of the people in the command ship, including myself, would probably have to feed the sharks, no wonder Nedwood was a little angry.

"The sonar comparison is complete, and the target sonar is characterized by a "Romeo" class submarine. The sonar soldier reported.

"Fart!" Nedwood couldn't wait to pick up the coffee cup on the table and smash the idiot sonar soldier all over the place. "This broken submarine is fucking older than my age, and its noise of up to 160 decibels can literally shake the Empire State Building of the Empire of the Rice Country, how did it break through the so-called most advanced anti-submarine encirclement in the world and infiltrate the core of our aircraft carrier formation?"

At this time, almost all the warships in the formation gathered intelligence on the command ship, and the conclusion was that they had found a "Romeo"-class submarine, which was surprisingly consistent in model, location, course, speed, and depth, which made Nedwood have to believe it.

Submarines have always been known for their "covert annihilation of the enemy," and the development of submarine-launched cruise missiles has posed a huge threat to aircraft carrier battle groups. In order to guard against a surprise attack from underwater, the aircraft carrier battle group needs to work hard to expand the anti-submarine defense circle during the voyage, and try to find and destroy enemy submarines beyond the range of submarine-launched weapons. At present, the normal anti-submarine defense range of the United States aircraft carrier battle group in the state of navigation is about 200 kilometers, which is divided into three layers of defense.

On the first floor, two S-3 anti-submarine aircraft are deployed on both sides of the formation or about 200 kilometers in front of the formation, cooperating with P-3C shore-based anti-submarine patrol aircraft and carrying out anti-submarine patrol aircraft according to a certain route.

In the second layer, 2~4 attack nuclear submarines are deployed in an arc in front and flanks of the battle group navigation sequence, 100~180 kilometers away from the mothership, using advanced submarine integrated sonar system, low-speed navigation submarines more than 60 kilometers away from the submarine can be found, and anti-submarine missiles and torpedoes are used to attack.

The 1st and 2nd layers of anti-submarine nets have a defensive range of more than 150 kilometers and can effectively destroy enemy submarines before they enter the range of their submarine-launched cruise missiles.

Layer 3: The main object of defense is the enemy submarine that breaks through the first two layers of defense and attacks with torpedoes. The anti-submarine force at this level is composed of 3~4 anti-submarine destroyers and anti-submarine helicopters carried by each escort ship. The former is equipped with an advanced SQR-19 towed line array sonar and is deployed at a distance of about 50 km from the mothership? The latter is generally deployed 20~30 kilometers in front of the mothership, and uses hoisting acoustic buoys, sonar buoys, magnetic detectors, and airborne and shipborne torpedoes to carry out the inner anti-submarine of the battle group.

The "Romeo" class submarine is a World War II submarine of the former Soviet Union, which has been around for 60 years now, and is simply the grandfather of the submarine family, with only six 533mm torpedo tubes in the bow and two 533mm torpedo tubes in the stern, and no anti-ship missiles.

However, such grandfather submarines also posed a great threat to the aircraft carrier fleet at that time, because almost all the warships in the fleet came into its torpedo range. Moreover, the torpedo it is equipped with an active and passive combined sound guide type, which can actively search for sound signals from warships and attack after launch.

Once the attack misses, the torpedo will automatically search for and attack the next sound target, so once the submarine is locked and attacked, it is basically impossible to escape. In particular, the USS Washington, the largest and slowest aircraft carrier, can also hit with torpedoes fired with its eyes closed.

"Take off the anti-submarine helicopter, carry out three simulated attacks, and send a signal to the submarine, ordering it to rise urgently within five minutes, and if it does not comply, it will be treated as an act of hostility and resolutely sunk."

Nedwood gave the order and sat down in his chair in a languishing manner. I'm really afraid of whatever I want, one or two planes have lost in the United States, and dozens of planes crash in training every year, but let alone an aircraft carrier worth $3.5 billion, it's an Ali? The unit price of Burke-class destroyers is also as high as 1.8 billion US dollars, and they absolutely cannot afford to lose. Not to mention that a warship was sunk and damaged by the other side, even allowing this broken submarine to enter its own anti-submarine warning zone is an unforgivable fault of a lifetime.

Nedwood pondered quietly where the submarine of unknown nationality came from. This submarine is equipped with many countries, but due to its range, it does not come too far.

In the vicinity, the countries that have had such submarines are the former Soviet Union, Huaxia and **. The first thing to exclude is the former Soviet Union, this kind of old submarine The former Soviet Union has long been swept into the garbage heap, but Huaxia and ** are still using this old submarine.

Could it be that Huaxia sent it? According to intelligence, although there are still about 30 improved "Romeo"-class submarines in service in Huaxia, this kind of old submarines that have been in service for more than 30 years are usually used for training and are hardly used for combat operations.

Moreover, even if you want to find out the reality of your own fleet, you should not send such a tractor-like broken submarine, and the loud noise, like a searchlight in the night, is too conspicuous.

Otherwise, the current **Under the leadership of their third-generation leaders, the whole country is arrogant and arrogant, and it has become a little neurotic. They fanned the flames everywhere and stirred up trouble, and it is very likely that they sent them, after all, this type of submarine is the most advanced submarine in China, and this submarine is still given away by Huaxia for free.

PS: Thank you very much to the leader of the football king brothers. Tomorrow is finally a little free, strive for two watches, and today is still a watch.
