"Look at the takeoff data first. If it is feasible, conduct a landing test. When you come to other tests, like what you mentioned in the air refueling, we have to contact the air refueling engine first. It will definitely not be done well at once."

Mr. Huang and Mr. Li thought for a while, then looked at each other for a last time before expressing their suggestions.

"The tanker is easy to deal with. The 81st Division has a tanker, and they also have related training programs. It is no problem to have a temporary training."

Yang Haisheng sat with the two old men, and understood what they said, and immediately said that the tanker was easy to deal with.

"Okay, that's it."

This will save Huang and Lao and the others from contacting the tanker temporarily, so they decided to do other tests first, and then conduct difficult tests such as aerial refueling.

With such a decision, this test was very different from what was planned before, and the first flight test also turned into a comprehensive whole-machine test experiment.

Please contact Yang Haisheng to contact Commander Lin of the 81st Division, and Xu Ziling returned to his seat.

"All units should pay attention, 'Shadow Dragon One' will enter the speed test immediately."

A command spread in the communication system, and all staff members in the control center and outside the site took action quickly.

"Prepare is complete!"

After waiting for less than a minute, Xu Ziling received a report that the test was ready.

"Supersonic cruise of four thousand meters!"

Hearing the report, he spitted a command from his mouth, put his hand on the drone control terminal, let go of the drone's slow cruise, and entered manual control.

After taking over the manual control, his hand moved, and the altitude remained unchanged. Don’t consider overloading. Control the plane to accelerate suddenly, allowing the plane to immediately enter supersonic flight.

In the large screen, a sonic bomb suddenly appeared at the tail of "Shadow Dragon One", and the speed began to increase greatly.

"Mach 1. Normal."

As the drone accelerated, the staff immediately reported its speed.

“Mach 1.5. Normal.”

"Mach 2. Normal."

“Mach 2.5. Normal.”

“Mach 3. Normal.”

Xu Ziling has been controlling the drone to accelerate, and the staff's reports have not stopped.

“Mach 3.5. Normal.”

"Mach 4. The body trembled."

While controlling the drone, Xu Ziling also kept paying attention to the various data of the aircraft. Before the report could sound, he also saw tremors on the screen of the drone on the control terminal. He also knew that at this altitude, the speed of Mach 4 was almost at its limit.

So while stopping the acceleration movement in his hands, he controls the plane to slow down.

“Mach 3.9 is flying normally.”

"The signal transmission of the detection equipment is normal, and the screen synchronization is clear."

"Flying 5 kilometers at 3.9 is normal."

"The signal transmission of the detection equipment is normal, and the screen synchronization is clear."

At an altitude of 4,000 meters, Xu Ziling felt it necessary to conduct a new altitude test.

"Prepare for an altitude flight test of 8,000 meters."

When a new instruction is issued, the staff immediately starts saving data and begins to welcome a new round of testing.

When everything was ready, Xu Ziling, who was controlling the drone, began to control the "Shadow Dragon One" and began to climb.

Just when it reached the altitude of 8,000 meters, the drone stopped moving upwards and began to maintain its height, and new tests began to begin.

The plane itself is very fast, so the test is very fast. It won’t take long to complete the test at an altitude of 8,000 meters.

After this altitude, we conducted tests of 12,000 meters, 20,000 meters and 24,000 meters.

Finally, it was concluded that drones can reach a maximum speed of Mach 5 between 8 and 20,000 meters. No matter how high the fuel is, it has to be reduced due to incomplete combustion of the atmosphere. However, when testing 24,000 meters, Shadow Dragon One can also reach Mach 4, which is much faster than the current highest reconnaissance aircraft, which is very exciting.

Even though the Lion had said this before, after seeing it with his own eyes, Xu Ziling was as excited as everyone else. If it weren't for the test now, he would have really wanted to laugh to the sky.

“Test the limit height.”

After calming down his excitement, he spat out another instruction.

The altitude of 24,000 meters, even the relatively best high-altitude reconnaissance aircraft, was quite good, but Xu Ziling was still a little dissatisfied. Besides, he also wanted to see what extreme height the "Shadow Dragon" could fly to, so he had such a test that was not originally planned.

Others were shocked by the previous tests and were also very interested in this extreme height. After hearing what Xu Ziling said, they were busy again, and they were also focused on watching and watched on the big screen.

“25,000 meters, normal flight.”

“26,000 meters, normal flight.”

“…”

“35,000 meters, normal flight.”

“36,000 meters, normal flight.”

“36,100 meters, normal flight.”

"36,200 meters, the power part data is abnormal, the analysis of insufficient oxygen supply and incomplete combustion."

As the reports were repeated, the drone became higher and higher. When it reached the altitude of 36,200 meters, news of an abnormal report finally came.

Hearing the report, Xu Ziling immediately controlled the plane and stopped climbing and began to pull it down.

"I don't get along much with what I expected!"

In my mind, Xu Ziling said to the lion.

"Of course, this aircraft originally focused on stealth ability, not flight altitude. Besides, it would be fine with this flight altitude. Even if they were flying over the sky, they wouldn't be able to hit the missile."

The lion has been paying attention to this test, and he responded to Xu Ziling's words quickly.

“That’s right.”

Although stealth unmanned attack aircraft is an attack aircraft, it is actually both for attack and reconnaissance.

While testing the flight altitude, they also tested the reconnaissance equipment on it. Whether at a few thousand meters or the highest flight altitude, Xu Ziling just glanced at it and saw that the photos sent back were extremely clear, even a little better than high-definition low-orbit satellites.

When reconnaissance is used, it can fly at an altitude of 35,000 kilometers. Not to mention the stealth function of the drone itself, it does not have stealth ability at this altitude. With today's most advanced air defense missiles, it is probably difficult to hit aircraft that can fly at high speed at this altitude.

Not to mention those fighter jets or interceptors, because once the aircraft is deployed, the drone will be able to detect the other side long ago. At a speed of Mach 5 below an altitude of 20,000 meters, Xu Ziling believes that even the most advanced f-35 in the United States is just a scumbag in front of it.

"Check to test the stealth function quickly. I haven't seen this thing before. I wonder if I can scan it after it is invisible?"

The most advanced and sci-fi color of "Shadow Dragon" is its stealth technology. Because there is a coating of nano-stealth material on the outside of its fuselage, the charging reaction of this material can make the aircraft truly disappear from the human sight.

Although the technology comes from the Lion system, he has never seen it before. I really don’t know if it can be scanned in this invisible state.

He had been testing other functions before, but at this time the Lion couldn't help it, so he brought it out to Xu Ziling.

Xu Ziling is also looking forward to this, after all, such technology is limited to those science fiction blockbusters.

He also became interested when he heard the lion mention it.

"Okay, I'll return immediately."

The drone tests at multiple levels of heights have been conducted on one line. Now the relevant tests have only been carried out, so it is best to be on the way back.

When he descended to an altitude of 12,000 meters, he manipulated the drone and began to turn back.

At the same time, a new test instruction was issued to the staff:

"Start return and prepare to test the stealth system, and pay attention to each department."

When everyone heard this, they were immediately excited.

Invisibility is the top priority of the "Shadow Dragon", not to mention that this incredible technology that can truly disappear from sight. Once successful, it will be a historical precedent and can be remembered by the world for the rest of their lives. How can everyone not pay attention to such a big event?

So as soon as he said that, both the staff and Huang Lao and others who were sitting and watching were extremely excited.

"The test time will start ten minutes, and after ten minutes, all radar observation departments will pay attention."

Looking at the excited staff, Xu Ziling didn't say anything. After all, he was the same as himself, and he could feel their feelings. He smiled and issued another order.

The maximum speed of Mach 5 was reached many times during the test, so the drone had already flown out of the Xinghai Province at this time, and the return speed did not increase to the highest, so it would still take some time to come back.

After calculating, Xu Ziling was about to start the test in ten minutes, because at that time, the plane arrived at the Xinghai Province and the relevant observation radar station could be observed at any time.

Nine minutes!

Eight minutes!

Seven minutes!

With the countdown of time, the hall that was just lively has now become silent. They either focus on the instruments in front of them or stare at the large screen showing satellite images.

One minute!

The last thirty seconds!

ten!

Nine!
