Phew~huh~

The fighter pulled out of the hangar, slid into the runway, and took off with a sudden afterburner.

The engine tail spout pulls out a blazing blue tail flame.

The twin planes took off and soared into the sky.

"716, 717, 10,000 on the high, 135 to keep!"

"716 received, 10,000 on the high, 135 on the course. ”

“717......”

Both fighters climbed and completed the steering at maximum speed.

This aviation base is responsible for air defense tasks in the southwestern direction.

At all times, there are two fighter jets with fuel and live ammunition, and they are on combat readiness duty in the hangar.

Usually the pilot waits in the lounge next to the hangar, and once he receives the order, he can quickly board the plane and depart.

Of course.

During major holidays and special periods, pilots will even sit in the cockpit.

If the security situation in the vicinity is severe, they will even take to the air to patrol with live ammunition and be ready to intercept enemy planes at any time.

Today.

The situation is also exceptional.

The long-range alert radar station found that a suspected stealth fighter had refueled in the air, and then its whereabouts were unknown.

Subsequently, various types of radars were turned on one after another, trying to find traces of stealth fighters.

Outcome......

Only the latest research and development, the most advanced, but still in the testing stage, ground-wave over-the-horizon radar, has been discovered.

Whether there is a problem with the radar or not, I don't know for the time being, but just in case, it is okay to send two fighter jets to confirm it visually.

Anyway, the large-scale use of graphene composite batteries and the increasing popularity of electric vehicles have led to a continuous decline in fuel prices, and the price of aviation fuel has also decreased.

Therefore, the two fighters took off once in an emergency, and the flight cost per hour was only hundreds of thousands, which seemed quite expensive, but it was much cheaper than before.

What's more, if foreign stealth fighters can be discovered and expelled, then this mission will not be a loss.

It's just that......

Ground-wave over-the-horizon radar, after all, is a new type of equipment that has just been developed.

New technical principles, new electronic devices, and various functions are not yet perfect.

Like those phased array radars that have matured, they can scan a wide range of targets while continuously tracking and locking multiple targets, and give the approximate characteristics, flight altitude, speed, and course of the target.

However, ground-wave over-the-horizon radar is not yet mature, and can only monitor a specific area, not a large area, while tracking and locking multiple targets can be, but the data is easy to be inaccurate.

After all, it relies on high-frequency radio waves, oscillating back and forth, unlike traditional radar, which sends electromagnetic waves out and hits the target and feeds back, so the credibility of the detection data is not enough.

It's not.

The target data reported to the two fighter pilots had only the approximate bearing and distance.

Flight altitude......

I don't know!

One moment it looks like 20,000 meters, and the next it looks like it's only a few kilometers.

The new radar is somewhat unreliable, so after the pilot flew more than 100 kilometers, he turned on the airborne phased array radar.

Fighter jets are in the air and are not affected by the curvature of the earth, so they can have a better 'reconnaissance vision'.

The mature airborne phased array radar can detect large flying targets at a distance of four or five hundred kilometers, such as passenger planes and cargo planes, and can also detect third- and second-generation fighters more than 100 kilometers away.

Of course.

If you want to find the fourth-generation stealth fighter, it is a little powerless.

The radar turned on and continued to scan for several minutes, but it was not found.

"Report 716, no suspicious targets found!"

"717 didn't find anything!"

The two fighters, separated by a continuous search and scanning, found nothing.

But the question is......

The ground-wave over-the-horizon radar still detects two targets as if it were nothing, and the speed is very fast.

"It's already very close to you, getting closer and closer to the border, flying at a speed of Mach 2, and the altitude may be 20,000 meters, you hurry up to 17,000, and observe it visually!"

Upon receiving the order, the two fighters immediately began to climb with afterburner.

After all, it is a third-generation light air defense fighter, and the flight limit altitude is 18,000 meters.

Flying further up, the engine will stop due to insufficient air intake and lack of oxygen.

Even if it was only 17,000, both pilots had to wear oxygen masks, and the flight loadsuit had to protect their bodies.

It's just that......

After more than ten seconds, the two fighters had climbed to an altitude of 17,000 meters.

The on-board phased array radar still did not detect targets flying at high altitudes and high speeds.

It can detect some flying targets, but the flight speed is very slow, less than Mach 1, and they are all with transponders on, which is obviously a civil aviation flight.

Where is there a target flying at twice the speed of sound?

Even if the phased array radar does not respond, then the electro-optical and infrared thermal sensing system, there should always be one, right?

There really need stealth fighters that can fly at Mach 2 speeds, even if they can be invisible to radar, and through technical means, the engine is protected from infrared detection......

However, they fly at high altitude and high speed, friction generates heat, coupled with the high-temperature and high-pressure airflow generated by the engine jet, even if the altitude of 20,000 meters is particularly cold, there will always be some infrared radiation characteristics.

But......

It is not detected by the on-board radar, and the optoelectronic infrared is not sensitive.

But the military order is like a mountain!

Two fighter pilots, simply by visual reconnaissance.

At an altitude of 17,000 meters, there are no clouds that obscure the view.

Looking up at the sky, it is a dazzling blue, and in the distance, you can see the curved skyline.

White clouds, floating in the low sky.

"The target suddenly turns sharply, you immediately turn to 85, the distance is 130, the speed is Mach 2, and the auxiliary fuel tank is thrown quickly!"

After receiving the order, the two fighters immediately threw the auxiliary fuel tanks and at the same time turned sharply.

When the fighter performs the mission, the range is increased by attaching the auxiliary fuel tank, and the fuel in the auxiliary fuel tank is also preferentially consumed when flying.

In the event of an emergency and the need to increase maneuverability, the drop fuel tank is discarded, reducing the load and air resistance, making the fighter more agile.

But......

No matter how flexible you are, no matter how much afterburner you drive, you can't fly faster.

Two third-generation light air defense fighters, although they have a maximum altitude speed of Mach 2.2.

But it is not equipped with any weapons, and the speed that the test pilot flies out during the test flight stage of the fighter can only be achieved in a short time, and it is extremely expensive, which will frantically burn aviation fuel and consume engine life.

And to achieve this speed, it is not in the blink of an eye, it is necessary to go through a relatively slow acceleration process.

It's like the dashboard of a family car, although there is also a maximum speed scale of 200 or 220 km/h, but in reality?

On highways, exceeding 120 km/h is already illegal and dangerous.

Forcing an acceleration to 160 km/h, the vast majority of engines are already quite weak, let alone soaring to speeds of 200 km/h or more.

The maximum speed on the scale is just the speed tested by the manufacturer on the test bench with an empty car.

If you really want to drive so fast in normal times, it is not far from the car crashing and dying.

But actually......

Subject to road conditions, regulations, and vehicle performance, even if the driver steps into the fuel tank, it is impossible for the family car to soar to a speed of 200km/h and above.

At this moment.

The two pilots were a little nervous in their hearts.

Having pushed the throttle to the bottom, the engine roared wildly.

The jet fuel was decreasing at a speed visible to the naked eye, and the fuselage of the fighter jet was shaking violently, and it felt like it was falling apart at any moment.

This is true for airplanes, and it is also true for cars.

Reaching a certain limit of speed and increasing it further can only overload the engine.

The engine will shake more and the noise will increase significantly.

Compared with automobiles, fighter jets face a harsher environment, with strong air resistance and intense air friction and heat.

But......

In order to pursue the target, I can't take care of it.

Results......

Still unsatisfactory.

The oblique pursuit passed, but the airborne phased array radar and photoelectric infrared sensing equipment still did not respond and did not detect it.

However, the base reported that the ground-wave over-the-horizon radar had detected the two high-altitude and high-speed targets, and the distance between them and the two fighters was narrowing, and they might encounter them, so that the two pilots could pay attention to visual observation.

Visual?

The two fighters further distanced themselves, and the pilots' eyes widened, and they didn't notice anything!

Could it be a ground-wave over-the-horizon radar with performance flaws and detection errors?

......

And the other side.

Two vulture fighters, using more advanced and powerful passive detection means, have long found two fighters.

The reason why they suddenly took a turn was to get around them.

After all, no matter how awesome the stealth technology is, it can deceive radar scanning and infrared detection, but there is no way to achieve optical invisibility.

That is, at close range, so that even human eyes cannot see.

Therefore, keeping a certain distance is conducive to their concealment and avoid detection.

But the question is......

When they turned sharply, why did these two fighters also turn sharply?

And keep a certain angle, and move towards them diagonally, and the speed is getting faster and faster.

What's the situation?

It shouldn't be a coincidence, after all, the timing of the turn and the course of acceleration are too obvious.

If it's not coming at them, why do you suddenly turn around, accelerate suddenly, keep getting closer?

But what puzzled the pilots was ......

Could it be that the vulture fighters, which cannot be detected by all the radars of country M, were detected by these two backward third-generation fighters?

When did Huaxia's computational electromagnetic technology become so awesome?

Now it seems to have been exposed, should this air raid mission be carried out?

Continue to fly over, and soon you will cross the border and break into the airspace.

The opponent may open fire at any moment, launch missiles.

Two Vulture pilots had a simple communication through the laser communication LAN between the fighters.

This special method of communication uses laser beams to irradiate information from each other.

Without generating any electromagnetic wave signals, point-to-point information exchange can be realized.

After all, for the sake of secrecy, the two vulture fighters had not been in contact with the base before, and were always in a state of radio silence.

At this juncture, it is impossible to rashly break the radio silence and ask if the base is exposed and whether it wants to continue the mission.

After a brief discussion, the two pilots made a decision.

Since it is a nirvana, where can there be a reason to give up halfway?

The other party may have a new type of radar with independent research and development and novel technology, which can detect them.

But what's the use of just detecting it?

Can you catch it, can you shoot it down?

The two vulture fighters immediately picked up speed, and after a few seconds they were raised to Mach 3, and continued to pick up speed.

This phenomenon, of course, was also quickly detected by ground-wave over-the-horizon radar.

Let the two fighters hurry after ......

Nima!

How can this be chased?

The throttle is pushed to the end, the engine is about to detonate, and the speed can no longer be faster.

Strength doesn't allow it at all!

As for the attack......

The target was not detected at all, so who did the missile hit?

If the missile could not find the target and ran to blow up the civilian airliner, it would be a big loss.

Now.

The fighter pilot asked whether the performance of this ground-wave over-the-horizon radar was reliable.

They didn't detect anything, and they didn't see it with their eyes, so could it be that the radar was misreporting?

It is also normal for radars that are being equipped with tests to have false positives of malfunction.

On the contrary, in today's world, it seems that there are no fighter planes, which can completely ignore all kinds of radar detection and all kinds of photoelectric infrared induction!

The two light fighters really can't fly!

With missiles hung, it's already good to be able to fly twice the speed of sound, and keep it for five minutes at most.

I want to chase Mach 3 and still speed up the unidentified flying target......

Isn't that what a strong man does?

Even if the fighter is scrapped, it won't be able to catch up!

Moreover, the fighter has already experienced severe tremors, the engine can not bear it, and the body structure cannot withstand it.

Maybe at any moment it could disintegrate in the air and let the pilot skydive? That would be no different from suicide.

Is it worth losing two fighter jets worth hundreds of millions for the sake of two high-altitude and high-speed targets that are not known to be true or false, plus valuable pilots that cannot be measured in money?

So......

An order was sent from the air base telling the two pilots to stop chasing, turn to reduce speed, reduce altitude, and return safely.

Of course.

Since the ground-wave over-the-horizon radar has detected that the two targets have crossed the border, it cannot ignore it.

So under the third-generation aircraft, on the fourth-generation aircraft.

It can be called a sharp weapon of the country, and the two stealth fighters that will not be used lightly have received orders.

From an inland aviation base, a two-plane formation was urgently lifted into the air......
