Qin Tao was indeed here to coordinate, but the person he was coordinating with was far away from the exercise sea area, so no one on the exercise ground noticed its existence.
"Report, dense data link transmission data has been collected, and deciphering work is in progress."
Luo Qiang nodded: "Our anti-ship missile directly killed one of their eight-thousand-ton target ships. At this time, they are discussing countermeasures. We will try to take advantage of this opportunity to crack their data link system."
For a modern military, data links are very important. With it, the three armies can communicate with each other to avoid accidental damage. Early warning aircraft can command a large number of fighter planes to fight, and various data and information can be transmitted at any time.
However, this also means that there will be counterattacks through technical means.
Just like the Global Satellite Positioning System, the Americans took the lead in researching and maturing this technology and produced a large number of low-cost precision ground attack JDAM bombs. However, at the same time, when the US military relied heavily on this technology, it also meant that their satellites
Once something goes wrong with the positioning system, they will become blind and deaf.
So in the later stage, they began to practice operations 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 this system.
The U.S. military commonly uses the Link16 data link, which uses time division multiple access technology. This technology allows each platform to send signals within a specified time and receive them at other times, avoiding a mess on site. 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, and the outside world cannot monitor it even if it wants to monitor it. In the Link16 data link era, there are a total of 3 frequency bands of frequency hopping points, a total of 51 random points, and an interval of 13
Subtle, that is, it changes 76,923 times per second.
With such a high frequency, not to mention deciphering, it is not easy to even keep up.
However, Dongfang has this ability because Dongfang has advanced computer systems!
"We have found their frequency hopping pattern, now follow their frequency hopping signal, and then decipher it!"
"We are doing violent deciphering and found that there are several regular words in it, which should be the names of the target ships!"
Computers are getting faster and faster. What is the use of such high computing speed? Just to calculate pi better?
Very useful!
Weather forecasts can change from one or two days to one or two weeks, and nuclear bombs can be completely simulated in computers without test explosions, making it easier to decipher them.
At that time, the first electronic computer ENIAC was actually developed to decipher German codes. In cryptography, there is a simple way to substitute various combinations into it. This is brute force cracking. It is like having
For a three-digit password box, if you don't know what the password is, try it a thousand times and you will definitely get it right once.
The faster the calculation, the more attempts are made and the easier it is to decipher.
"It's done!" Someone shouted loudly: "All their data link communication contents 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!"
"How about we create a false attack?"
"We take advantage of this opportunity to publicize the progress of Easterners in these fields and ask Congress to allocate more funds to us. Otherwise, we will not even be able to defeat the outdated warships of the East!"
These are just simple chats, other data are more important, such as the data format for transmission between warships, early warning aircraft and other equipment, such as command communication with drones...
East, Capital, Princess Tomb, Huanglou.
"The deciphering work has been completed. We can monitor all their data link communication messages in real time and understand their every move."
"Really? This is great!" Wu Shengli said: "From now on, they will be transparent in front of us!"
It's like there are sophons created by the Trisolaran world. From that time on, people on earth don't have any secrets, except in their brains.
"Dad, let's not get too happy too early. This is just a drill. After the drill is over, they might change."
The equipment cannot be changed, but the frequency hopping rules can be changed at any time. Once such a change is made, everything you know now will be useless and you will have to start over.
"That's not necessarily true. According to American business rules, it is normal to update it every two or three years."
In fact, changing the frequency hopping method is very simple. After one terminal is set up, the other terminals will be synchronized. After all, this is a centerless architecture. However, the Americans find it troublesome and do not update it frequently.
Just like in some confidential situations, the password is set to 0 for convenience. This kind of simple and low-level mistake is often made by Americans.
"Oh." Qin Tao couldn't keep pouring cold water on everyone. Since Wu Shengli said so, he couldn't refute anymore. Next, he rolled his eyes: "Dad, I have a new one."
idea."
"explain."
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, the 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 112 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 neither die nor wither!"
Countless people lamented on the Internet and cheered for the triumph of warship 112, while some people were worried.
"Would 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."
"When exposed, you are exposed. When it's time to draw your sword, you must draw your sword!"
Compared to 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, and 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, 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, representatives from 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, they 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?
Just as Raytheon's technicians were about to express the difficulty, the people from Lockheed Martin 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. It is most appropriate to leave 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 be completed.
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, as long as they increase the speed of the final stage, which will also make it easier to use their stealth machines."
The Yankees finally got back on the right track, gave up flying toads, and started to build the F-35. This aircraft will become the Yankees' main fighter, but when the weapons are built in, they will find that they can't take the big guys at all.
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 they only have 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 the good show of the Americans.
After saying this, Qin Tao talked about another thing: "Dad, did your superiors approve the suggestion I made last time?"
"Well, it's approved, and a small team has already set off."
Parthia.
This place has an important geographical location and is a powerhouse of energy. However, it has been turbulent for a long time. From the late 1970s to the present, there has been almost no peaceful moment. Perhaps, the eagle above our head is the eternal ruler of this world.
Bar?
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 a gray low-detectability coating.
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 made entirely 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, 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.
They haven't even flown over yet.
"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 can surrender 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 do you communicate with the rear through data links?
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 fly into space.
"Data transmission is normal, we are uploading the data we just downloaded!"
Just when they were deceiving the drone, they had already downloaded all the data detected by the drone. Now, the satellite above their heads is asking to upload this data, which can be transmitted back. In this way, in the rear
The drone operator should know that the drone is still performing its mission accurately at this time.
On the runway, the RQ-170 drone had just stopped, and a vehicle was already driving up quickly, blocking the runway in front of it. Someone went up to look for its power and oil switches.
