Warship of Great Power

Qin Tao did come to coordinate, but the object he coordinated was far away from the exercise area, so no one on the exercise field noticed its existence.

"Report, we have collected dense data link transmission data and are working on deciphering it."

Luo Qiang nodded: "Our anti-ship missiles directly destroyed one of their 8,000-ton target ships. At this time, they are discussing countermeasures. We will try to take this opportunity to crack their data link system."

For modern armies, data links are very important. With it, the three services can communicate to avoid accidental injuries, early warning aircraft can command a large number of fighters to fight, and various data information can be transmitted at any time.

However, this also means that there will be counterattacks by technical means.

Just like the global satellite positioning system, the Americans took the lead in researching and maturing this technology and developed a large number of low-cost precision ground attack JDAM bombs. However, at the same time, when the US military relies heavily on this technology, it also means that once their satellite positioning system has an accident, they will become blind and deaf.

So in the later period, they began to practice fighting without the help of the global satellite positioning system to avoid falling into despair without a positioning system on the battlefield. The same is true for the data link system. It can also be interfered with and even deciphered. Of course, it is not easy to decipher such a system.

The US military often uses Link16 data link, which uses time division multiple access technology. This technology allows each platform to send signals within a specified time and receive at other times to avoid a mess on the scene. At the same time, in order to avoid interference, it uses frequency hopping and spread spectrum technology.

Frequency hopping is already a very common technology. The frequency keeps changing. Even if the outside world wants to monitor it, it cannot monitor it. In the era of Link16 data link, there are 3 frequency bands for frequency hopping points, a total of 51 random points, with an interval of 13 microseconds, that is, it will change 76923 times per second.

Such a high frequency, not to mention deciphering, even keeping up is not easy.

However, the East has this ability because the East has advanced computer systems!

"We have found their frequency hopping pattern. Now we keep up with their frequency hopping signals and then decipher them!"

"We are conducting violent deciphering and found that there are several regular words in them, which should be the names of the target ships!"

The speed of computers is getting faster and faster. What is the use of such a high computing speed? Just to calculate pi better?

It is very useful!

Weather forecasts can be changed from one or two days to one or two weeks, and nuclear bombs can be simulated completely in computers without test explosions, which will make it easier to decipher.

Back then, the first electronic computer ENIAC was actually created to decipher the German code. In cryptography, there is a simple way to substitute various combinations into it, which is brute force cracking. It's like a three-digit password box. If you don't know the password, try it a thousand times, and one of them will definitely be correct.

The faster the calculation speed, the more times you try, and the easier it is to decipher.

"It's done!" Someone shouted loudly: "All their data link communication content can be deciphered by us!"

As long as you know the rules, you can know all the information content. Now, whether it is text, voice, or video, it can appear on their computer terminals!

"Damn it, this exercise has become their stage!"

"Should we create a false attack?"

"We take this opportunity to publicize the progress of the Orientals in these fields and let Congress allocate more funds to us, otherwise we can't even beat the old Oriental warships!"

These are just simple chats, and other data are more important, such as the data format transmitted between warships, early warning aircraft and other equipment, such as command communication with drones...

East, capital, Gongzhufen, Huanglou.

"The decoding work has been completed. We can monitor all their data link communication messages in real time and grasp their every move."

"Really? This is great!" Wu Shengli said: "From now on, they are transparent in front of us!"

It's like having a sophon created by the Three-Body World. From that time on, the earthlings have no secrets at all, unless they are in the brain.

"Dad, let's not be too happy too soon. This is just an exercise. After the exercise, they may change it."

The equipment cannot be changed, but the frequency hopping rules can be changed at any time. Once changed, what we know now will be useless and we have to start over.

"That's not necessarily true. According to the American way of doing things, it is normal to update it every two or three years."

In fact, the change of frequency hopping method is very simple. After one terminal is set up, the other terminals will be synchronized. After all, this is a decentralized system structure. However, the Americans find it troublesome and do not update it frequently.

Just like in some confidential occasions, for convenience, the password is set to 0. This simple and low-level mistake is often played by the Americans.

"Oh." Qin Tao couldn't keep pouring cold water on everyone. Since Wu Shengli said so, he couldn't refute it anymore. Next, his eyes turned: "Dad, I have a new idea."

"Say it."

After Qin Tao finished speaking, Wu Shengli opened his eyes wide: "This..."

"Dad, this is a rare opportunity. If you know yourself and the enemy, you will be victorious in any battle. We have to get the equipment in the enemy's hands so that we can fight tit for tat in the future."

"Okay, it's up to you. Let's report it." Wu Shengli nodded: "However, we have to wait until the exercise is over at the earliest."

"Um."

Because the 112 warships dispatched by the Eastern Navy killed the target ship with just one strike, this Rim of the Pacific military exercise ended in a hasty manner. The 112 warships did not participate in the subsequent subjects of the exercise. The exercise was originally scheduled for three days. , the day was over, and that night, the 112th warship embarked on its return journey.

And the inside story of this exercise is also spreading at an alarming speed.

"Ship 112 is so awesome!"

"A veteran will never die or wither!"

Countless people lamented on the Internet and cheered for the triumph of warship 112, while some people were worried.

"Will this arouse the fear of the Americans? They invited us to participate in the military exercise this time out of good intentions. They just wanted to see our strength. Unexpectedly, our trump card was exposed like this."

"Exposed is exposed. When it's time to show your sword, you must show your sword!"

Compared with the cheers of Eastern military fans, Westerners were silent.

The quantity cannot be compared, and the quality cannot be compared. Even the old Eastern warships have such powerful attack power!

The first person to speak was Asan. Pi Lai, the president of BrahMos Aerospace Corporation, made a public speech.

"The YJ-81 missile used by the Dongfang 112 warship is just a backward anti-ship missile. Although it sank the target ship, it doesn't mean anything. The most advanced anti-ship missile in the world is the Burla jointly developed by us and Damao. The Moss missile is a supersonic anti-ship missile that can fly at supersonic speeds throughout the entire process. It can not only be used as an anti-ship missile, but can also be used as a cruise missile..."

This is one of the few things Asan can do. In the mid-1990s, Asan and Damao jointly formed the BrahMos Company to develop modern anti-ship missiles. By 2004, this missile It has just been put into production, and the number of equipment is currently very small. However, this is still enough to double Ah San's confidence. If it is their anti-ship missile, the effect will be even better!

However, no one paid attention to Ah San. Everyone expressed their contempt for Ah San's behavior of trying to gain popularity. Who doesn't know what you, Ah San, are thinking.

However, shortly after Ah San issued the statement, the Americans finally took action.

Pentagon.

"Dongfang's anti-ship missiles only increase the speed to Mach 1.3, but they bring such powerful power. We must not lag behind on this track. We must also develop advanced supersonic anti-ship missiles, and the speed must be higher! Jed Ford, the head of the Navy's anti-ship missile project, looked at the representatives of the two companies present: "The Navy's requirement is for our brand-new missile to reach a maximum flight speed of Mach 5!"

As soon as these words came out, the representatives of Raytheon and Lockheed Martin in the conference room were stunned.

What a joke!

The United States has never developed a supersonic anti-ship missile. Previous anti-ship missiles, whether Harpoon or Tomahawk, were subsonic. Later, it developed a stealth missile, which was still subsonic.

They have no experience in this area. It is not easy to develop advanced anti-ship missiles, not to mention that they have to reach Mach 5!

How can this be?

The technicians from Raytheon Company were just about to express the difficulty, but the people from Lockheed Martin Company had already recovered from the shock: "Of course there is no problem. Our Lockheed Martin Company has rich experience in the development of hypersonic aircraft, and it is most appropriate to hand over this project to us." ”

The people at Raytheon Company immediately understood that it didn't matter whether he could do it or not, he had to get the project first.

"Our company has been developing missiles all the time. We have the most experience. There is no problem in leaving it to us!"

"Okay, in order to ensure the smooth development of the project, we will place an order with your two companies!"

In the past, the Yankees' procurement projects were subject to bidding. This time, because they took a gamble, and also because they had discovered that they lacked such advanced anti-ship missiles in their arsenal, they simply gave it to both bidders. Order!

Without disclosing it to the outside world, the Americans placed orders with Raytheon and Lockheed Martin, with a total value of over 100 million. The goal of this order was to design a new anti-ship missile, codenamed HALO, which stands for Hypersonic Airborne Missile. Shoot attack missiles!

Although this matter was secret, it quickly spread to the east. After Wu Shengli returned home, he looked at his son-in-law and said with a smile: "Taozi, the Americans are going to build Mach 5 anti-ship missiles, what do you think? Are you scared?"

"Are you kidding? The Americans must be crazy." Qin Tao said: "After exceeding Mach 3, there will be many problems waiting for them. They also want to develop Mach 5 missiles. This project will eventually Ended with failure."

"Well, we think so too. Now Americans also like to launch satellites. Things are changing!"

"Actually, the most suitable choice for the Yankees is to learn from us. Just increase the speed of the final stage, which will also be more convenient for their stealth machines."

The Yankees finally got back on the right track, gave up flying toads, and started working on the F-35. This aircraft will become the Yankees' main fighter, but when the weapons are built in, they will find that there is no way to bring the big guy.

The Yankees can only tailor-make weapons systems for this kind of aircraft, such as anti-ship missiles. After searching through their arsenal, they found that there is only the JSM from Confsberg, Norway. Although this missile is a stealth model, The range is short, and the warhead weighs only 125 kilograms, which is much smaller than the 165 kilograms of the Eagle 81, and lower than the 221 kilograms of the Harpoon warhead.

If you want to increase your attack power, you can only increase the speed. We have already shown our advanced results to the Americans. The Americans don't know how to learn. Instead, they find another way to launch larger satellites!

Then just wait and see what the Americans can do.

After saying this, Qin Tao talked about another thing: "Dad, did your superiors approve the suggestion I made last time?"

"Well, it's approved. A small team has already set off."

Parthia.

It has an important geographical location and is a major energy country, but it has been in turmoil for a long time. From the late 1970s to now, there has been almost no peaceful moment. Perhaps the eagle above the head is the eternal ruler of this world, right?

At Isfahan Airport, someone raised his head and looked at the sky.

"It's here, it's here again!"

"Hmph, you're bragging about some stealth technology, but it's still a prototype in front of our radar!"

"Xiao Li, don't brag and do your job well!"

"yes."

At this time, in the sky, a delta-wing-shaped aircraft was slowly flying over. Its appearance was very similar to the B2, but its appearance was smaller. Because it was a drone, it used an air intake layout above the nose. , which is exactly the opposite of the belly air intake. Since it was flying during the day, the color of the skin also changed to gray low-detectability paint.

This is the Yankee’s most advanced RQ-170 stealth unmanned reconnaissance aircraft!

Prior to this, the most important reconnaissance aircraft of the Yankees was the RQ-4 Global Hawk. This aircraft has a similar appearance to the U-2 and has the ability to fly at high altitudes for a long time. Although the surface is also coated with a stealth coating, its stealth capabilities are not professional. The stealth aircraft is powerful and can fly in ordinary airspace, but in some special areas, it is easy to be discovered and attacked.

The Americans knew the flaws of the Global Hawk, so after the new millennium, they began to develop stealth unmanned reconnaissance aircraft. After several years of development, the RQ-170 was born!

It has a wingspan of twenty meters, is entirely made of composite materials, and has first-class stealth capabilities. Now it is flying to the Isfahan Air Force Base, using its high-precision optical equipment to detect movements on the runway.

It believes that it will not be discovered by the ground and can easily complete reconnaissance activities. It does not use radar equipment with synthetic aperture function and will not radiate any electromagnetic waves. Even the data link is only adjusted to the receiving function and does not transmit any signals. .

It was like a ghost, still a ghost of the day, slowly flying over.

Suddenly, its data link received a message.

Upload investigation data!

During the testing of the drone, these instructions were often given, so it accurately uploaded the relevant data, although it did not know that there was no US military data link terminal nearby to communicate with it at this time, not even the satellite above its head. Didn't even fly over.

"Reply received!" Someone below became excited: "It's completely feasible. Next, we need to send a new command!"

Aim for the runway and prepare to land!

In the absence of external instructions, it will fly according to its own preset procedures, but as long as there are external instructions, it needs to listen to the outside world. At this time, the drone carried out the orders seriously.

It adjusted its course according to the target coordinates it received, aimed at the runway below, and then started the landing procedure.

Getting closer and closer. At this time, it didn't know what it was doing at all. It just followed the order. On the runway, countless people raised their heads and looked at the approaching drone, with mixed emotions. .

"It actually dares to fly above our heads. We should have shot it down long ago!"

"Now that it has surrendered to us, it shows that it knows that the Yankees are evil."

"This doesn't look like a Global Hawk. What is it?"

While they were discussing, the drone continued to land. When the wheels began to make contact with the runway, a communications satellite was flying overhead.

The Link16 data link works in the L-band. Although it is very advanced, the maximum transmission distance of electromagnetic waves is only 550 kilometers. It is enough for a battlefield, but it is not enough for equipment that works at long distances, such as fighter jets. Leaving the mothership, you may have to fly thousands of kilometers to carry out bombing missions. So how to communicate with the rear through the data link?

This requires specialized relay aircraft, which can also be achieved using satellites. In comparison, satellites are more convenient. Therefore, as early as more than ten years ago, the U.S. Navy and Air Force had already relied on satellites for relay.

This satellite is also used as a relay satellite for RQ-170.

"Attention, block the drone signal immediately!"

Strong electromagnetic interference was generated at Isfahan Airport, and the landing drone was unable to make any effective contact with the outside world.

In the distance, on a special vehicle, electromagnetic waves flew into space.

"Data transmission is normal, we are uploading the data we just downloaded!"

When they were deceiving the drone just now, they had already downloaded all the data detected by the drone. Now, the satellite above their heads asked them to upload these data, so they could just transmit these data back. In this way, the drone operators in the rear should know that the drone is still accurately performing its mission at this time.

On the runway, the RQ-170 drone had just stopped, and a vehicle had already driven up quickly, blocking the runway in front of it. Someone went up to look for its power and oil circuit switches.
