Great warships

Chapter 1237: Veterans Will Not Wither
Qin Tao did come to coordinate, but the object he was coordinating 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 currently working on deciphering it."

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

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

However, this also means that there will be counterattacks through technological means.

Just like the global satellite positioning system, the Americans were the first to research and mature 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 if there is an accident with their satellite positioning system, 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 being in despair without a positioning system on the battlefield. The same is true for the data link system, which can also be interfered with and even deciphered. Of course, it is not easy to decipher such a system.

The US military often uses the Link 16 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 chaos 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, and even if the outside world wants to monitor it, it cannot. In the Link16 data link era, there are 3 frequency bands for frequency hopping points, with a total of 51 random points, with an interval of 13 microseconds, which means that it changes 76923 times per second.

With such a high frequency, it is not easy to even keep up, let alone decipher it.

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

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

"We are currently trying to decipher it violently. We found several regular words in the code. They should be the names of the target ships!"

Computers are getting faster and faster. What is the purpose of such high computing speed? Just to calculate pi better?
Very useful!

Weather forecasts can be extended from one or two days to one or two weeks, and nuclear bombs can be completely simulated on computers without test explosions, making them easier to decipher.

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

The faster the calculation speed, the more attempts there are, and the easier it is to decipher.

"It's done!" someone shouted loudly, "We can decipher all their data link communications!"

As long as they know the pattern, they 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 alarm?"

"We should take this opportunity to publicize the progress of the Orientals in these areas and ask Congress to allocate more funds to us. Otherwise, we won't even be able to defeat the Orientals' outdated warships!"

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

East, Capital, Gongzhufen, Huanglou.

"The decoding work has been completed. We are now able to monitor all their data link communication messages in real time and understand their every move."

"Really? That's great!" Wu Shengli said, "From now on, they will be transparent to us!"

It is like the intelligent beings created by the Three-Body World. From that time on, the people on Earth no longer have any secrets, except in their brains.

"Dad, let's not be too happy too soon. This is just a drill. After the drill is over, they might change."

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

"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 mode is very simple. After one terminal is set up, other terminals will be synchronized. After all, this is a decentralized system architecture. However, the Americans find it troublesome and do not update it frequently.

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

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

"explain."

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

"Dad, this opportunity is rare. Knowing ourselves and the enemy will ensure victory in every battle. We must get the equipment in the hands of the enemy so that we can fight back in the future."

"Okay, I'll listen to you and report it." Wu Shengli nodded: "But the soonest we can do that is after the exercise is over."

"Ah."

Because the 112 warship sent by the Eastern Navy destroyed the target ship with just one missile, the Rim of the Pacific exercise ended in a hasty end. The 112 warship did not participate in the following subjects of the exercise. The exercise, which was originally scheduled for three days, ended in one day. That evening, the 112 warship embarked on its return journey.

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

"Ship 112 is amazing!"

"Old soldiers never die, nor fade away!"

Countless people expressed their feelings on the Internet, cheering for the triumphant return of the 112 warship, while some were also worried.

"Will this arouse the Americans' fear? They invited us to participate in the military exercise this time with ulterior motives. They just wanted to see our strength. Unexpectedly, our trump card was exposed like this."

"It's exposed, so let's show our swords when it's time to do so!"

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

The quantity is not comparable, and the quality is not comparable. Even the old-style warships from the East have such powerful attack power!
The first speaker was Ahsan. The president of BrahMos Aerospace, Pilai, made a public speech.

"The Eagle Strike-112 missile used by the Eastern 81 warship is just an outdated 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 BrahMos missile jointly developed by us and Russia. This is a supersonic anti-ship missile that can fly at supersonic speeds throughout the entire process. It can not only fight against ships, but also be used as a cruise missile..."

This is one of the few things India can show off. In the mid-04s, India and Russia jointly established the BrahMos company to develop modern anti-ship missiles. It was not until that this missile was put into production. The number of equipment is very small at present, but it is still enough to make India more confident. If it is their anti-ship missile, the effect will be better!
However, no one paid any attention to Asan. Everyone expressed contempt for Asan's behavior of trying to get attention. Everyone knows what you Asan are thinking.

However, shortly after India made its statement, the Americans finally took action.

Pentagon.

"The Eastern anti-ship missiles have only increased their speed to Mach 1.3, but they have brought such powerful power. We must not fall behind in this race. 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 that our new missiles reach a maximum flight speed of Mach !"

When these words were spoken, the 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, it developed a stealth missile, which was still subsonic.

They have no experience in this area, and it is not easy to develop advanced anti-ship missiles, not to mention that they have to reach Mach 5 at once!
How can this be?

Just as the Raytheon technicians were about to express their difficulty, the Lockheed Martin staff had already recovered from their shock: "Of course there is no problem. We at Lockheed Martin have extensive experience in the development of hypersonic aircraft, so it is most appropriate to entrust this project to us."

The people at Raytheon immediately understood what was going on and decided to get the project first, regardless of whether it would work or not.

"Our company has been developing missiles for a long time. We have the most experience. It will be no problem to leave it to us!"

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

In the past, all the Americans’ procurement projects had to be bid. This time, because they were taking a gamble and also because they had discovered that their arsenal lacked this advanced anti-ship missile, they simply placed an order with both bidders!

Without making it public to the outside world, the Americans placed orders with Raytheon and Lockheed Martin, with a total value of over 100 million yuan. The goal of this order is to design a new anti-ship missile, code-named HALO, which is a hypersonic air-launched attack missile!
Although this matter was kept 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 develop Mach 5 anti-ship missiles. What do you think? Are you afraid?"

"What a joke! The Americans must be going crazy." Qin Tao said, "After exceeding Mach 3, there will be many problems waiting for them. They still want to develop a Mach missile. This project will definitely end in failure."

"Yeah, we think so too. Now the Americans also like to make false claims. Things are changing!"

"In fact, the best option for the Americans is to learn from us. All they need to do is increase the speed at the end, which will also make it easier for their stealth aircraft to use."

The Americans have finally returned to the right track, giving up the Flying Toad and starting to develop the F-35. This aircraft will become the main fighter of the Americans, but once the weapons are built in, it will be found that there is no way to carry the big guy.

The Americans can only tailor-make weapon systems for this type of aircraft, such as anti-ship missiles. After searching their own arsenal, they found that there was only the JSM from Norway's Kongsberg. Although this missile is a stealth model, it has a short range and a warhead weighs only 125 kg, much smaller than the 81 kg of the Eagle Strike 165 and even smaller than the 221 kg warhead of the Harpoon.

If we want to improve our attack power, we can only increase our speed. We have already shown our advanced achievements to the Americans, but they don’t know how to learn from them. Instead, they are taking a different approach and launching larger satellites!

Then just wait and see what the Americans have to offer.

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

"Yes, it's approved. A small team has already set out."

Parthia.

This place has an important geographical location and is also a major energy country, but 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 heads is the eternal ruler of this world?
At Isfahan Airport, someone looked up at the sky.

"Here it comes, it comes again!"

"Humph, you're still bragging about your stealth technology, but your prototype is revealed in front of our radar!"

"Xiao Li, stop bragging 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 that of the B2, but it was smaller. Because it was a drone, it used an air intake layout above the nose, which was exactly the opposite of the air intake on the belly. Because it was flying during the day, the skin color was also changed to a gray low-detectability paint.

This is the Americans’ most advanced RQ-170 stealth unmanned reconnaissance aircraft!
Before this, the most important reconnaissance aircraft of the Americans 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 it is also coated with a stealth coating on the surface, its stealth capability is not as strong as that of professional stealth aircraft. It can fly in ordinary airspace, but it is easy to be discovered and attacked in some special areas.

The Americans knew the shortcomings 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 came out!

Its wingspan is as long as 20 meters and it is made entirely of composite materials, with first-class stealth capabilities. Now, it is flying towards 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 on 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 if it is a data link, it is only adjusted to the receiving function and does not transmit any signal.

It was like a ghost, a daytime ghost, flying slowly towards us.

Suddenly, its data link received a message.

Upload reconnaissance data!

During the drone testing process, these instructions often appear, so it accurately uploads the relevant data, although it does not know that there are no US military data link terminals nearby to communicate with it, and even the satellites overhead do not fly over.

"We got a reply!" Someone below got excited: "That's totally feasible. Next, we need to send a new command!"

Align to the runway and prepare to land!
In the absence of external commands, it will fly according to its preset program, but as long as there is external command, it needs to listen to the outside world. At this time, the drone executes the command 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, it had no idea what it was doing at this moment. It was just following orders. On the runway, countless people looked up at the gradually approaching drone with mixed feelings.

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

"Now that it has surrendered to us, it means it knows that the Americans are evil."

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

As they were talking, the drone continued to land, and when its wheels began to touch the runway, a communications satellite was flying overhead.

The Link16 data link operates in the L band. Although it is very advanced, the maximum transmission distance of electromagnetic waves is only 550 kilometers, which is enough for a battlefield, but not enough for equipment working over long distances. For example, a fighter jet may have to fly thousands of kilometers away from its mother ship to carry out a bombing mission. How can it communicate with the rear through the data link?

This requires a special relay aircraft, but it can also be achieved using satellites. In comparison, satellites are more convenient, so as early as more than a decade ago, the US Navy and Air Force have already used satellites for relaying.

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

"Attention, block the drone signal immediately!"

Strong electromagnetic interference occurred at Isfahan Airport, and the landing drone could no longer make any effective contact with the outside world.

And in the distance, from 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 kinds of data detected by the drone. Now, the satellite above their heads requires uploading this data, so they can just transmit this data back. In this way, the drone operators in the rear should know that the drone is still performing its mission accurately at this time.

On the runway, the RQ-170 drone had just landed when a vehicle drove up quickly and blocked the runway in front of it. Some people went up to look for its power and oil switches.
