The grasslands in August have cooled down, and the temperature is only four or five degrees Celsius at two or three o'clock in the morning.

Zhang Xingyang and Song Tianxing stood side by side on a small hill, chatting with each other.

The chats were wide-ranging, ranging from the integration of black holes in the depths of the universe to the education of children.

However, the most of the content of the conversation between the two was about the design of the fighter and the future form of air combat.

"The battlefield of future wars will be much bigger than it is now."

Zhang Xingyang looked up at the sky, there were countless dark clouds blocking the starry sky that should have been shining brightly today.

Raising his finger, he pointed to the now invisible space and said:

"Space will be a battlefield that will be fought for in the next era of warfare."

"Whether it's reconnaissance satellites used for reconnaissance, or navigation satellites used to provide guidance and positioning work for weapon systems, they will shine."

The wars after the twenty-first century, compared with the wars of the previous century, have become more abundant in reconnaissance means.

Unmanned reconnaissance aircraft equipped with high-definition cameras and even infrared thermal imaging cameras are military satellites that can provide a wide range of field of view.

All of them make the fog of war smaller and smaller, and for technologically advanced countries, such advantages are especially obvious.

"This is especially true in the context of local conflicts."

After listening to what Zhang Xingyang said, Song Tianxing only felt that his throat was extremely dry, and he said in a hoarse voice:

"Is this the war we will face in the future?"

Although Zhang Xingyang did not describe the scene of the war in detail, Song Tianxing was still able to imagine the picture of the future war.

Highly stealthy fighter jets in the sky command dozens of drones and pilots in crazy battles, and every moment the drones turn into a fireball after the missiles launched by the pilots hit.

But the swarm composed of intelligent drones, even if damaged, will not make people feel distressed, dozens of high-speed maneuvering unmanned fighters, encircling the pilots who are piloting the fighters.

After the pilot launched all the air-to-air missiles he carried, he was killed by an ultra-long-range air-to-air missile fired by a stealth drone in the distance.

Obviously, Song Tianxing was wrong about the identities of the two sides in the war described by Zhang Xingyang.

He thought it was the enemy who used such tactics.

After all, no one proposed such a combat system before Zhang Xingyang told him.

"The intensity and speed of future wars will exceed everyone's imagination."

Zhang Xingyang didn't care about the dust on the ground, sat down directly, looked at the dim sky and said:

"What we can do is to try to improve the performance of weapons and equipment."

"Only by holding a sharp blade can you not be afraid of the jackals, tigers and leopards in this world."

In fact, Zhang Xingyang did not say many things about the future war.

For example, in the 20 years when satellite reconnaissance and unmanned aerial vehicle reconnaissance technology were just emerging, in fact, war was a different picture.

This is especially true when both warring parties have significant industrial capacity.

The development of electronic technology has made it possible for even those who cannot produce their own high-precision cameras to find suppliers from the civilian market that can be used.

Drones with high-precision cameras and even thermal imaging are used to shuttle across the battlefield day and night.

Even if you are wearing a camouflage suit and hiding in a swamp, you are no longer safe, and you can wait for a bullet from an enemy sniper or an air-dropped grenade from a drone operator.

This is only to play the reconnaissance role of UAVs, and the simple assembly of unmanned cruise missiles has made the king of land, the main battle tank, which was once built with a lot of money, face greater air risks.

A third-generation main battle tank that costs tens of millions of dollars will still be blown up in the face of a cruise missile costing tens of thousands of dollars.

Of course, these are the belligerents in a war that have not established a system of warfare.

For a high-quality army, such a situation is very difficult.

Because heavy armored units cannot act alone, they must have accompanied anti-aircraft missile vehicles, unmanned automatic anti-aircraft weapon stations, and so on.

Capable of minimizing possible air strikes.

When cruise missiles come, not to mention anti-aircraft missiles with ultra-high strike accuracy, even automatic air defense weapon stations that only use 20-mm cannons can strafe these slow and proper cruise missiles, which are known as small air motorcycles.

This is mainly due to the intelligent image recognition in the excellent radar system and optical reconnaissance system in the automatic weapon station.

For an army with a well-developed combat system, a wide range of high-tech weapons systems are almost standard.

This is only the application of civilian-level high-precision cameras in small UAVs, large reconnaissance and strike integrated UAVs, in addition to not being able to carry out high maneuverability, in fact, there is no difference from the stealth unmanned delta-wing fighter just elaborated by Zhang Xingyang.

The operator who controls the large reconnaissance drone can find and strike at the enemy on the screen like a game in the safety of the rear.

"We still have a long way to go if we want to complete the construction of such a combat system."

Zhang Xingyang saw the deep worry of Song Tianxing beside him after figuring out this combat system, smiled and said:

"Don't worry too much, Brother Song."

"It is impossible for any country in the world to build this combat system within 20 years."

"There's just so much technology here that needs to be developed."

Even if it seems that it can be done now, it is very difficult to operate a drone with a manned warplane.

The main reason is that the current communication technology is not very developed, taking the 3G technology that has just been formulated as an example, the data that can be transmitted is less than 1/10,000 of the 5G technology in later generations.

However, through manned fighters to operate several UAVs at the same time, at least a few gigabytes of data need to be transmitted every second, otherwise it is difficult to ensure that these fighters can accurately complete the scheduled actions in high-intensity combat situations.

Of course, after the advent of high-level artificial intelligence, the transmission speed per unit of time is required to decrease.

But the technology also comes with high demands.

"Let's do what we're doing first."

On the distant horizon, there is already a glimmer of white light, the night is about to pass, and the day that belongs to us is coming.

——

In the next few days, Song Tianxing led the fighter design team almost day and night to conduct fighter wind tunnel experiments.

At one time, there were even certain problems with the power supply of power plants.

Because at the beginning of the design, the thermal power plant did not take into account the possibility of three wind tunnels working at the same time.

After all, every time the wind tunnel is turned on, a large amount of power supply is required, and if the design can meet the requirements at the same time, then the instantaneous power of the thermal power plant will be very large.

From an economic point of view, such construction is really wasteful.

After all, in each wind tunnel, the time of a single experiment is mostly no more than 100 milliseconds, and it is not difficult to stagger the time a little.

"Mr. Song, can you take a break?"

Qiao Yang, who was in charge of hypersonic ballistic missiles, was forced to be a little unbearable, because Song Tianxing and they experimented almost day and night, and their wind tunnel experiments were almost suspended.

Song Tianxing didn't know how many days he hadn't rested, his eyes were red and he looked at Qiao Yang on the side and said:

"Give us one more day and we'll be able to finish."

Even Qiao Yang, who stayed up late to work all year round, was taken aback by Song Tianxing's extremely poor physical condition.

"Mr. Song, do you want to find a doctor at the base to take a look?"

"It's really unreassuring for you to be like this!"

"Ahem."

After Song Tianxing coughed twice, his voice was a little hoarse:

"I'm fine, I know my own body."

"Our experiments have reached the last moment, and we can't stop yet."

Although Song Tianxing didn't admit that he had a physical problem, Qiao Yang still didn't believe it.

Anyone who saw this old man with red eyes, messy hairstyle, and a tired face would not think that his condition could be much better.

"Xiaofu, have the latest changes been arranged?"

Ignoring Qiao Yang, who was frowning in front of him, Song Tianxing said to his assistant on the side.

"The latest adjustment of the tail wing tilt angle. Ay! ”

"Mr. Song!"

Before the assistant could finish reporting the situation, Song Tianxing fell softly on the floor of the laboratory.

"Mr. Song!"

"Call the doctor!"

Qiao Yang was also frightened by Song Tianxing, who suddenly fell to the ground, but he realized that he had to call a doctor first.

Because the wind tunnel base has to ensure the medical problems of thousands of people in the base at all times, it maintains a 24-hour standby medical team at all times.

Able to provide emergency treatment to scientific researchers who have problems in the base in a timely manner.

The patient is then transported by helicopter to a tertiary hospital hundreds of kilometers away.

The doctor came over quickly, and it only took a minute or two to arrive at the lab.

"Spread out, spread out!"

"The doctor is here!"

Song Tianxing's assistant asked everyone to stay a little away from Song Tianxing's body to leave him room to breathe.

The doctor first listened to Song Tianxing's heartbeat, and breathed a sigh of relief, the heart rate was quite normal.

Then he opened his eyelids and looked at his eyes, which were full of bloodshot eyes, which surprised all well-informed doctors.

There were not too many problems at the scene, but in case of accidents, the doctor still asked the stretcher team that came with him to carry Song Tianxing on the stretcher.

Prepare to go to the base hospital for a more comprehensive examination.

After stopping the fighter design team's intention to follow him to the hospital, he only asked Xiao Fu, who had been in charge of Song Tianxing's life, to follow him, ready to ask about Song Tianxing's condition during this time.

——

"What?"

"Song Tianxing is sick?"

Zhang Xingyang, who was in the office of the base, was also a little hard to believe after receiving the call.

After all, a few days ago, when Song Tianxing met him, he was still in good health.

Although he is already dozens of years old, he is very energetic in both work and life.

How did you fall ill in just a few days?!

However, Zhang Xingyang didn't have time to think too much, and hurried to the hospital at the base.

Although there are thousands of people living on the base, there are not many people in the general hospital.

It is only during the monthly routine medical check-up that it will be more lively.

Today, outside the door of the hospital, there are exceptionally many people.

Most of them were Song Tianxing's colleagues and students.

"Mr. Song, how is the situation now?"

Zhang Xingyang saw so many people at the gate, and immediately asked.

"Dean Zhang, now we don't know the situation of Mr. Song."

The crowd at the door didn't know exactly what was going on.

Zhang Xingyang could only reluctantly walk into the hospital, ready to ask the doctor how Song Tianxing's condition was.

When I walked into the hospital hall, I saw the assistant Xiaofu anxiously circling in place.

"Xiaofu, what about you Mr. Song?"

Seeing Zhang Xingyang coming, Xiao Fu, who was already extremely anxious, collapsed instantly.

The man, who was almost thirty years old, squatted directly on the ground and cried.

"Mr. Song, still in the operating room!"

Xiao Fu said while crying:

"It's all because I didn't remind Mr. Song, if he had a good rest, it wouldn't be like this!"

From Xiao Fu's intermittent words, Zhang Xingyang also sorted out what the situation was.

In the past few days, Song Tianxing has been able to complete the finalization of the fighter as soon as possible, day and night.

Although his health has always been good before, after all, he is already in his sixties, and his cardiovascular and cerebrovascular systems are not very good.

Coupled with the fact that I didn't rest for a long time, the blood vessels in my mind exploded, and I fell to the ground directly.

After Zhang Xingyang heard this, he was also taken aback, Song Tianxing was so desperate, obviously stimulated by some of the things he mentioned before.

"Mr. Song, you have to be safe, otherwise I will become a sinner."

Zhang Xingyang looked at the red light that was still on in the operating room, and prayed silently in his heart.

Maybe the prayer really worked, or maybe Song Tianxing himself was blessed with a great life.

After an hour of hard waiting, the red light in the operating room finally dimmed.

"Doctor, how is Mr. Song's condition?"

Zhang Xingyang hurriedly stepped forward to ask as soon as the doctor came out.

The doctor took off his mask, exhaled and said:

"For the time being, my life has been saved, but the conditions of our base hospital are limited, and we have to be transferred to the northern capital for follow-up treatment."

"Doctor, can his body now withstand such a long transport?"

Although Zhang Xingyang does not know much about medical treatment, he has lived in this era for a long time and knows that patients are prone to all kinds of accidents on the way to transport.

"With helicopter transfer, the time doesn't need to be very long, there is no big problem."

The doctor's answer can be regarded as giving Zhang Xingyang and Xiao Fu a reassurance.

"Doctor, then hurry up and transfer, I'll apply for a route."

Zhang Xingyang said as he took out his mobile phone and began to contact the Air Force.

The application for domestic routes has always been the responsibility of the Air Force, and with Zhang Xingyang's friendliness in the Air Force, coupled with Song Tianxing's identity as the new fighter commander, the route was approved almost instantly.

Half an hour later, Song Tianxing, who had completed the preliminary management, boarded a helicopter to the northern capital.

He will receive further treatment at the Air Force General Hospital in the Northern Capital. (End of chapter)
