What does it mean to get a perfect score on the college entrance exam but then go missing?

Yanliang Airport was clearly bathed in sunshine under a clear blue sky.

But now, everyone feels suffocated and unable to breathe.

There is no other reason.

Everything they heard and saw was so shocking.

A massive aerial behemoth weighing tens of tons took off from a distance of less than one hundred meters.

This demonstrates the extraordinary performance of the aircraft's engine.

This engine alone is enough to outperform all other aero engines, including the F119.

But this is not the end.

This aircraft also features an integrated high-temperature ceramic-based metamaterial skin and an onboard plasma stealth generator.

Zhao Changhong didn't even know exactly what these two technologies were.

But he knew that these two technologies would give the aircraft a radar cross-section of less than 0.0001.

This performance is enough to make it outperform all fifth-generation fighters.

"So, your aircraft can achieve true signal stealth?" Zhao Changhong asked in alarm.

Qin Ze nodded: "This aircraft will reduce the radar detection range to within 63 kilometers. Even if it secretly reveals some signals during takeoff, it will lose the interception window."

Zhao Changhong felt a chill run down his spine.

As the chief engineer of Xi'an Aircraft Industry Group, and as a designer of high-end military aircraft.

He has spent half his life researching invisibility.

He could understand all too well the shock that Qin Ze's words had.

Conventional aircraft have significant vulnerabilities during takeoff, making them easily targeted by multi-base radar and meter-wave radar.

However, Qin Ze's aircraft has a stable RCS of less than 0.0001, which means that the fuselage, tail nozzle, air intake, and wings have been optimized for stealth across the entire frequency band and all angles.

Even if it can reveal a tiny bit of signal on radar, its extreme stealth capabilities compress the radar's detection range.

By the time the radar detects the signal, it has already moved out of its range.

In a practical sense, this is complete signal stealth.

Thinking of this, Zhao Changhong felt a chill run down his spine: "Do you have any evidence for what you're saying, especially the data on signal stealth?"

"Where am I supposed to find evidence for you?"

Qin Ze was so angry he laughed.

If we really want to test the data on signal stealth, we must have the cooperation of advanced radar.

There are only a handful of these machines in the whole country, and they are all controlled by the military.

Qin Ze and his team had no opportunity to conduct experiments to verify the findings.

"The data is based on our theoretical calculations and is rather conservative."

Zhao Changhong's heart tightened. You call 0.0001 conservative?

"But it's normal if you don't believe me."

Qin Zefeng said calmly.

"You can call the Western Desert Military Region and ask if they've seen it."

……

……

Two hundred kilometers away, at station A118.

Hidden among high mountains and dense forests, the millimeter-wave radar rotates continuously.

This is the conventional radar combat readiness base of the Western Desert Theater Command, equipped with a fixed millimeter-wave radar with a detection range of up to 2000 kilometers and the highest detection accuracy among all air forces.

Airfield A118 has successfully tracked three of the US's main stealth fighter jets, earning it the honorary title of "Flying Fortress" from the military.

Behind the meritorious service lies the excellent management system of the station and the dedication of the officers and soldiers.

At one o'clock in the afternoon, observer Zhang Xiaohu picked up his teacup and drank the last mouthful of strong tea in one gulp.

This was his last shift.

After six hours of continuous surveillance, his fatigue reached its limit, and his attention was about to wane.

But as the first line of defense for the motherland's airspace, he still tried his best to draw his attention back and keep his eyes glued to the radar screen.

suddenly!

A faint white dot appeared in the lower right corner of the radar, its signal so weak it was almost negligible.

But Zhang Xiaohu immediately perked up.

According to regulations, any unusual activity on the radar must be recorded and reported, and the cause must be investigated.

Zhang Xiaohu opened the spectrum and carefully analyzed the characteristics of the signal, discovering that the signal hovered almost on the radar's detectable line, about the same as a noise point.

Unlike noise, this signal appears continuously, not just flashes by, and is most likely emitted by an aircraft.

then.

Zhang Xiaohu immediately pulled up today's air traffic control records.

This document contains all the approval records for aircraft within the jurisdiction, with routes and times clearly marked.

If it is indeed noise signal from a civil aircraft, it can be investigated and ruled out by comparing it with the approval records.

but.

Zhang Xiaohu searched through the records thoroughly but couldn't find any that met his requirements.

This made his heart leap into his throat, and his movements became increasingly exaggerated.

Upon seeing this, the duty officer, Xiao Weibing, immediately went behind Zhang Xiaohu and asked, "What's wrong? Why are you in such a hurry?"

"Squad leader, there's an abnormal signal." Zhang Xiaohu immediately pulled up the signal spectrum.

Xiao Weibing looked at the screen, frowning slightly: "It shouldn't be noise. Has the civil aviation authorities checked?"

Zhang Xiaohu: "I checked everything, and it doesn't match. Could it be an illegal flight?"

"impossible."

Xiao Weibing has worked at the station for ten years and is very experienced.

He said resolutely.

"If it were any form of unauthorized flight, we should be able to receive a continuous signal, but we only received a three-second continuous signal. What does this mean?"

Zhang Xiaohu continued, "That means it immediately moved out of the detection range!"

Xiao Weibing's expression turned grave: "Or! He's gone invisible!"

Holy crap!!

Zhang Xiaohu was young and couldn't hold back.

Neither of these two possibilities is acceptable to the airfield.

If it's the first one.

The fact that the aircraft was out of radar detection range within three seconds indicates that it covered a distance of 2000 km in those three seconds.

What kind of performance is this?

UFO?

If it's the second possibility.

If a stealth aircraft appears in the western hinterland, it means that the air defenses have been completely breached.

From today onwards, the entire air defense system will likely undergo a major overhaul.

These consequences far exceeded Zhang Xiaohu's expectations, leaving him somewhat flustered.

Fortunately.

As the squad leader, Xiao Weibing still retained a sliver of rationality.

He immediately picked up the direct line.

This is an encrypted satellite line that connects directly to the joint command center, enabling the mobilization of massive forces.

"This is station A118!"

"Emergency! Unidentified flying object intrusion, code 13!"

"The radar detected a weak signal, which disappeared within three seconds. The location was 051,087, and the altitude was 2,000 meters."

"Preliminary assessment indicates it is a hypersonic stealth aircraft; its intentions are unclear!"

"It is recommended that the investigation be extended to Unit 081!"

"Repeated: UFO intrusion, we may be under attack!"
