In the end, Xu Ziling still didn't tell the drone about it, and maintained the most mysterious thing.

When a few minutes later, the "Shadow Dragon No. 1" swept across the sky like a black lightning bolt into Lin Jianbin Jianbin 's line of sight, he was completely stunned.

The rest of the crew members who were in the same crew as him were exceptional, because the figure of the "Shadow Dragon One" was so shocking to them.

Xu Ziling controlled the plane side by side on the side of the tanker, made a swaying motion, and said hello to Lin Jianbin in the tanker.

"I said you should give me permission instructions quickly, otherwise how can I refuel?"

"This ...... That's what it is...... You say drones? ”

Lin Jianbin, who was dumbfounded for a while, stammered.

"Isn't this a drone?"

Xu Ziling held back a smile and answered him.

Most of the domestic UAVs are biased towards electronic reconnaissance, and attack aircraft are not absent, but those are not mentioned by them in terms of energy or combat power.

He told Lin Jianbin that it was a drone before, and Lin Jianbin naturally thought that he was also a reconnaissance model, and he didn't think that it was an attack plane.

But at this time, when he saw the cool appearance of the "Shadow Dragon One" with its wings swaying outside the cabin, he was the most uncommon sense and could recognize that this was an unmanned attack aircraft.

Of course, if this is an ordinary unmanned attack aircraft, he will not have this reaction, the main thing is the shape of this pull, so that he can know at a glance that the road is a stealth attack aircraft, and then think of the speed he saw just now, he can roughly guess some of the xìng capabilities of this drone.

"I'll pass it on to you right away, pay attention to the reception."

Thinking that as soon as his task was completed, he would go to the military factory, Lin Jianbin didn't ask much at this time, and got busy with business.

The permission command is a verification procedure for the fuel dispenser, without which the fuel pipeline of the fuel dispenser will not be opened.

Xu Ziling's side soon received it

Lingkey, immediately entered it into the drone's system, and at the same time controlled the plane to slow down and leave the side of the tanker and come to its tail.

The fuselage of an air tanker is quite large compared to a drone, with long hoses extending from each side of its tail.

And these two hoses are its fuel pipes, and the aircraft that needs to be refueled must be connected to it with its own fuel pipes in order to achieve refueling.

The speed of the tanker in the air is quite slow, but due to the huge fuselage and the huge thrust of the engine, the air flow in its tail is also very large.

This makes it possible to refuel the aircraft in the air, which is also a very difficult task.

Xu Ziling controlled the plane behind the tanker, and immediately felt the huge air flow from the picture from the drone.

After slowly adjusting and stabilizing the drone again, he turned on the refueling pipeline on the plane.

Due to the stealth of the drone, its refueling pipe is also retractable, and it is usually hidden in the fuselage.

Press the control button, and the fuel filling tube will slowly and automatically extend out of the fuselage.

When it was all extended, he controlled the drone to move forward slowly, and aimed the fuel pipes at the fuel pipes of the tankers.

Three meters!

Two meters!

One meter!

0.5 meters!

Getting closer and closer, soon the drone shook slightly, and I saw that the fuel pipeline of the tanker and the refueling pipe of the drone were firmly combined.

Verify, open the fuel valve.

Immediately, the amount of fuel began to increase.

"It worked."

Seeing this result, everyone cheered, and immediately realized that they were still working, and immediately fell silent again.

"When will it be done?"

Taking advantage of the time to refuel, Lin Jianbin talked to Xu Ziling again in the channel.

"When will it be done?"

Regarding Lin Jianbin's sudden headless and brainless words, Xu Ziling suddenly didn't figure out the meaning of his words.

"Uh...... When will the drone land? ”

"Oh, this, not yet, yet, there are new test items, and it will be at least four or five hours before you return."

This kind of trivial matter has nothing to hide from Lin Jianbin , so Xu Ziling told him clearly.

"How long is it going to take? What are you going to test? ”

Lin Jianbin was very surprised by this answer.

Indeed, according to the speed of the drone he saw before, staying in the sky for several hours, if it flies in a straight line, four or five is even half, then I don't know where the road can fly, what project will be tested for so long?

"I'm going to go to the 'Liaoning' for a walk, do you want to take a look?"

I haven't seen Lin Jianbin for a long time, so Xu Ziling simply took this opportunity to ask him to come over and have a look.

“……”

Hearing that he was going to get on the aircraft carrier, Lin Jianbin was taken aback again,

"Come on, why don't you come, I'll come over as soon as I get off the plane."

Then he shouted excitedly.

"Huh...... Then you just come over and wait for me to speak, or you can call the fat man yourself and ask him to pick you up. ”

"Okay, I'll contact the fat man myself later, so you don't have to say hello."

Wang Jian, as a manager of the military factory, was also in the audience at this time, so he could naturally hear the internal and external communication in the hall.

Hearing Lin Jianbin say this, Xu Ziling looked at Wang Jian below, nodded at him, and motioned him to wait to pick up this guy in.

Wang Jian saw Xu Ziling's actions and nodded to indicate that he knew what he said.

Seeing Wang Jian's statement, Xu Ziling didn't care much anymore and refocused on the drone.

When the "Shadow Dragon 1" took off from the airport again, in order to test in-flight refueling, the ground crew did not refuel it, but the first flight was not long, and the drone that took off with full fuel at that time did not use much.

Not long after refueling on an air tanker, it prompts a full tank of fuel.

Hearing the prompt, the valve of the aircraft fuel tank was also automatically closed, and Xu Ziling disconnected the fuel pipe and the fuel pipeline of the tanker with the drone.

Put away the refueling pipe, control the drone to leave the refueling plane in parallel for dozens of meters, and then an acceleration is parallel to the refueling machine again, swing the wings and say hello to Lin Jianbin , and climb away with a sharp acceleration.

"I'm leaving."

"Well, I'll be back right away, and I'll be there later."

At this point, the project of the air refueling test was officially completed, and after the two said yes, Xu Ziling also took the initiative to interrupt the communication between the two.

When he was just waiting for takeoff, he had already contacted the "Liaoning", and the coordinates were also given, and Xu Ziling was also told that he was ready on the aircraft carrier, just waiting for the arrival of the drone.

Xu Ziling entered the coordinates on the UAV navigation system, and the distance between the aircraft carriers was immediately displayed.

He looked, and there were less than two thousand kilometers between the two.

Unlike the previous Thunder, the Shadow Dragon 1 can be reached in less than 20 minutes at a top speed of Mach 5.

However, he didn't control it to fly so fast, but continued to test all kinds of maneuvering abilities along the way.

In fact, in the case of the "Shadow Dragon", as long as there is an advantage in speed and weaponry, maneuvering is not so important.

Because it has the best stealth ability, in the state of extreme speed, it can silently fly behind the enemy or the target location, and then use the weapon to strike at the target, and it can completely use the speed that other fighters or ordinary anti-aircraft missiles cannot reach to quickly leave.

This can be said to be not much danger for it.

However, for the most complete test, Xu Ziling still controlled it to carry out its own tactical maneuvers.

Of course, the results of the test are also undoubted, after all, the drone does not need a pilot to do it, and there is no need to consider overload, as long as the aircraft can withstand it, and the maneuvering can be sufficient, any difficult maneuvers can be easily made.

So after making a few difficult moves, he didn't test it again, controlled the plane to adjust the direction, and flew directly in the direction of the aircraft carrier at a maximum speed of Mach 5.

Ten minutes later, the "Hawkeye" radar system control center on the "Liaoning".

A radar soldier noticed that a plane hundreds of kilometers away was flying in their direction at an incredible speed on the radar display screen in front of him.

He saw that this speed was a little abnormal, so he immediately calculated it, but the calculation result made him instantly dumbfounded, thinking that he had miscalculated, but after calculating it again, it was still this result, and he immediately stood up in a trembling manner:

"Report!"

"Say!"

An officer next to him said.

"Boss, you...... You'd better check this out. ”

The radar soldier was completely shocked by the speed of the plane, and his speech was incoherent, and he also shouted out the private address of the superior officer when he was on duty.

The people who could serve on the aircraft carrier were carefully selected by Jīng, and when the officer heard such an unusual performance of his subordinate soldiers, he did not reprimand him at the first time, but hurriedly ran to his side.

"What?"

"Look at the speed of this plane."

The radarman immediately pointed to a signal on the screen, and then took out the results of his two calculations.

"Mach 5? How can it be? Are you not mistaken? ”

Seeing this result, the officer shouted in surprise.

The signal point of the plane on the screen is green, which proves that the plane is definitely filed in the identification system of friend or foe, but at this speed, not to mention the aircraft produced in their own country, even the most advanced fighters in Western countries do not have this speed.

"Take a look at the picture of this plane right away, and I'll report to the top."

This situation was so abnormal that even if the system said that it was not an enemy plane, the officer still hurriedly reported it to his superiors.

Asked the soldier below to check the scan of the plane on the system, he immediately picked up the communicator and began to report to the above:

"According to the report, the 'Eagle Eye' found that a friendly plane was flying at an extremely abnormal speed two hundred kilometers away towards our base, and according to the calculation results, the flight speed reached Mach 5."

"What? Again, Mach 5? ”

An unusually surprised voice immediately came from the communicator.
