Liao Gong looked at him and said paragraph by paragraph, and said angrily:

"Zhao Kai, don't sell it, let's talk about the point, and then grind and chirp, and transfer you to the third and fifth classes next month!"

The technical officer named Zhao Kai almost burst into laughter, pushed his glasses and hurriedly begged for mercy: "I'll just say, don't let me raise pigs, it's inappropriate." I'll just say that. ”

The head of the Air Force waved his hand and said, "Don't say anything, let's go, let's go and see for ourselves." ”

In the humble production hall, a pile of badly aged lathes was piled aside, and a new Warrior was placed in the vacant space. Several circuit boards were screwed to the body, connected to the outside power supply by bundles of wires. Around the car, some different styles of instruments and devices are facing the body, receiving relevant data.

As soon as the group entered the workshop, they heard someone talking loudly and excitedly.

"The results of the 66 Hz current detection are out, and the current in the 65 to 67 Hz range can be exempted from the 7-14 GHz radio wave band; According to the IEEE521-2002 standard, part of the C-band, all X-band, and part of the Ku-band are exempt. ”

The head of the Air Force is familiar with this frequency band.

"Isn't this the band used by the Eagle Sauce Missile Defense Agency to track extremely long-range targets and support the defense of the high-altitude area at the end of the theater? Are you saying that this stealth board can ignore radio waves in the X-band? ”

The excited Zhao Kai didn't know the head of the Air Force, but he knew the star on the chief's shoulder. hurriedly saluted a standard military salute.

"Report chief, exactly! We found that this stealth circuit board lives up to its name, and under different currents and hertz numbers, electromagnetic waves of different frequencies can penetrate; The 66 Hz we measured just now is exempt from some microwave frequencies, including the X-band. In other words, if our warships, warplanes, satellites, and missiles are equipped with this kind of stealth circuit board and work at 66 Hz, even if Eagle Sauce installs THAAD in the South Stick House, it will be blind. ”

"Are you sure?" The head of the Air Force couldn't believe it, knowing that the thing THAAD was placed in the South Stick House, and it was a huge threat to the Rabbit Family;

South Stick where THAAD uses a ground-based mobile AN/TPY-2, X-band solid active multifunctional phased array radar, with a detection range of more than 2,000 kilometers. It can detect stealth targets with a small radar cross-section at a distance of 1,000 kilometers, and has considerable anti-stealth fighter capabilities. Due to the narrow beam used, it is possible to accurately assess the expected position of the target warhead within 600 kilometers and identify the false warhead.

Such a thing is placed at the door of the house, and the rabbit is called a stalk in the throat; He did not hesitate to use some less glamorous means to force Minami to give up this thing. As for whether it has an effect, it's hard to say, but the Eagle Sauce family's Sade has taken root in the South Stick family.

General Zhang, who had never opened his mouth, asked very suspiciously:

"As far as I know, THAAD's ground-based SBX radar claims to be able to identify a baseball-sized flying object from 5,000 kilometers away, are you sure this board can hide from the ground-based radar?" Although he expected this thing to be magical, there was something more magical about this thing than he had imagined.

Zhao Kai had seen the bureau, and hurriedly said: "General Zhang, this is the most amazing thing about the stealth circuit board, it is not stealth through absorption or refraction like our existing stealth materials, but directly exempts the beam of a specific frequency band, as long as this circuit board has been working, the beam of a specific frequency band can penetrate through it and the objects it is attached to without hindrance." This current frequency of 66 Hz is just enough to dispense with X-band radar waves. ”

"Good! Good! Good! The head of the Air Force said three good words in a row, and then said happily: "If this small circuit board can really make THAAD blind, I will give you credit!" ”

Then Zhao Kai said again: "Report chief, it's not our credit, it's really the person who made this stealth circuit board is too good." This thing can not only be stealthy to THAAD, but if we can make the band of the scanning radar recognized, it can be used by changing the current frequency of the power supply. Theoretically, it is possible to dispense with all detection beams, including a variety of long-wave, short-wave, microwave, infrared, and even visible light. ”

Liao Gong asked, "Have you tried out the visible light too?" ”

"Tried it out!" Zhao Kai smiled toothily at Liao Gong, and then shouted to the soldier who controlled the power supply: "Xu Yile, change the power supply, let's try visible light stealth again." ”

"Roger!"

After confirming the order, the technical officer turned his head again and said, "Chief, General Zhang, Liao Gong, next, it is time to witness the miracle." ”

As soon as his words fell, a surprising scene appeared, only to see that the warrior suddenly began to appear refractive reflections that only glass can have, and then became more and more transparent, the warrior's square edges showed a diamond-like cut angle light, and in less than thirty seconds, the warrior was already like a crystal sculpture.

"Xu Yile, increase the current! Put it in 12 amps! ”

"Current 12 amps."

As the current intensifies, the warrior who could still see the silhouette becomes shallower and shallower, and finally disappears into the air as a completely transparent object.

The whole process takes less than a minute.

However, it is invisible to the naked eye, but the instrument simulating X-band electromagnetic waves next to it emits an alarm sound, and it depends on the situation that the X-band electromagnetic waves can be detected again.

"This ......" General Zhang saw a car with a volume of 20 cubic meters disappear in front of him, and couldn't help but step forward, wanting to reach out and touch it.

Zhao Kai hurriedly grabbed him: "General Zhang, the voltage and current used on the circuit board have exceeded the limits of the human body, and there is a certain danger, we can't guarantee whether the body conducts electricity, you better wear a pair of gloves and touch it." ”

While speaking, a worker handed over a pair of insulated rubber gloves, General Zhang was not polite, put on the gloves and touched them again, and there was a cold and solid touch in the empty place as far as his eyes could see.

"Really invisible?" Then he fumbled for the car door again. With a click, the door lock opened.

General Zhang tried to stick his head in and look, but he didn't see the interior and console like James Bondrie's stealth car.

"General Zhang, we have all tried, the whole car is in an invisible state, if you don't close the door, you can see the outside when you sit inside, but once the door is closed tightly into a sealed space, you can't see anything when you sit inside. It's not because the light is dark, it's like entering a world where there is no light at all. ”

General Zhang was eager to experience what it was like to be completely devoid of light; It's just that when the car was electrified, the testers didn't dare to let him into the car naked.

The head of the Air Force asked: "How did you do this stealth?" ”

Zhao Kai explained: "Chief, the frequency of this visible light stealth is the best to remember and the most convenient. When the current frequency is 0 Hz, the board can be visually invisible! ”

The head of the Air Force did not react for a moment. "0 Hz? What kind of current can achieve 0 Hz? ”

"Direct current!"

The head of the Air Force almost didn't roll his eyes, you are playing a brain teaser.

Just as General Zhang was about to put on an insulated suit and enter the warrior car, a rush of footsteps came.

Before anyone arrived, the voice had already arrived:

"Liao Gong, there is a major discovery in the circuit board that dissolves water!"
