Chapter 1199: Driving away F22

In fact, when the F22 formation passed through the Z-shaped connection line of the dual-base radar for the first time, the radar station in Jingnan had already detected a set of obvious Doppler beat frequency phenomena through the beat frequency receiver.

This means that several targets invisible to ordinary radars have passed through the connection line.

But this is still just a rough direction judgment and cannot really determine the specific location of the target.

Therefore, Jiang Zengjian on the early warning aircraft immediately ordered the two Su-27SKs that were preparing to return to the base to turn their noses south and search the suspicious area delineated by the dual-base radar.

As a pilot himself, he certainly knew that the detection range of the N001 radar for the F22 was probably not as good as the IRST on the nose of the aircraft, and could not really pose a threat to the opponent.

However, such a sudden and unexpected event may force the opponent to change its course or altitude, thereby exposing the side and rear with a relatively large RCS.

Of course, if this were a real fight, these two Su-27s would undoubtedly become bait.

However, when the equipment level is at a disadvantage, there is no better way.

What's more, when they were thinking about using the J-6 and J-7 to fight the F-14, they might not even have the chance to be bait...

However, things were not as easy as Jiang Zengjian thought.

After exposing his tracks for a moment, the opponent disappeared from the radar screen again without leaving him any more useful information.

He had originally decided to order the two J-11B squadrons that had been on standby at the airport to take off, but now he hesitated again.

When the entire plan was being drawn up, comrades from the Equipment Research Institute repeatedly emphasized to him that Doppler beats are different from radar echoes. They will only appear once on each connecting line and are completely incapable of measuring height. Therefore, it cannot be ruled out that a flock of flying birds or floating balloons or the like may have caused the false alarm.

It would be best to let the radar network itself detect the echo signal. Even if it cannot track stably, at least it can determine the nature of the target and avoid being paranoid.

What's more, he doesn't have many cards in his hand. If he plays them out casually like this, if he misses, there will be an interception window of at least two to three hours.

By then, even if we discover the enemy again, there will not be enough air power to deal with them.

But then again, it takes time for the plane to take off and enter the interception position...

After thinking for a moment, he took a deep breath, marked an airspace range in the command system, and leaned close to the microphone:

"Huanghe, this is Changcheng. Have Qinling Team 1 take off and search the airspaces I have marked, P7 and P8. Team 2 will continue to stand by, especially paying attention to low altitudes!"

After he finished speaking, he paused for a moment and then added:

“Huaihe, stop returning and head to P7 and P8 airspace, but remember to lower your altitude first to prepare for landing, then do not climb, fly low along the coastline… After completing the mission, land directly nearby…”

"..."

……

When Colonel Robinson saw four new Flankers appear on the multi-function display and all flying straight towards the southeast, he finally confirmed that he must have been discovered.

Or, at least, it was discovered.

Because the opponent was preparing to fly forward in a line at a considerable distance.

This is a signal to conduct an air search, not to prepare for combat.

And the direction was not aimed at his formation.

But even so, he probably no longer had the opportunity to penetrate directly to within 20 miles of the opponent's coastline as originally planned.

For a moment, he couldn't figure out which link had gone wrong.

But now, we have no choice but to switch to the alternative plan -

In fact, in the original plan, even if they really approached the Chinese airspace quietly, they would open the ammunition bay to conduct a simulated attack and deliberately expose themselves.

If the other party does not respond, then retreat normally.

And if the enemy takes off to intercept, then use the remaining fuel to let the Chinese experience the suppressive power of the fourth-generation fighter jets.

Now, it’s just a matter of skipping the middle step and coming directly to the second branch route.

"Activate Plan C, prepare to climb, and confront them head-on!"

Robinson issued instructions to the other three planes in the formation.

In order to avoid radar detection, they just lowered their altitude a bit, which will inevitably have some negative impact on the subsequent competition.

Fortunately, the F22's maneuverability and agility are surprisingly strong, and it is destined to be far superior to any Chinese fighter.

Soon, another set of dual-base radars with Jincheng as the transmitting end detected four targets that were climbing at large angles.

Although the echo signal was intermittent, it was enough to confirm that it was not a bird or a balloon.

The relevant information was quickly reported to all pilots involved in the interception.

The Qinling 1 team, which had been conducting a large-scale search aimlessly, regrouped and flew towards the F22 formation.

The two Su-27SKs that were still heading south also readjusted their routes, preparing to attack from the north.

The eight aircrafts were more than 160 kilometers apart, their radars were scanning each other, but none of the aircrafts had their radar warning systems light up.

The F22's AN/APG-77 radar uses the latest flexible beam technology, which can reduce the probability of being captured by RWR during the search and even tracking and locking process.

As for Qinling Team 1, they really haven't found the target yet. The performance of the 1493 radar is of course far superior to the N001, but as Colonel Robinson estimated, 160 kilometers is still too far.

However, the stealth advantage is bound to diminish as the distance decreases.

At a distance of about 100 kilometers, four J-11Bs captured the echo signal almost simultaneously.

Inside the cockpit of Qinling's lead plane, pilot Ji Pingfeng stared at the radar information displayed on the HUD in amazement.

The four planes were climbing rapidly at a nearly vertical angle and had reached an altitude of 5500 meters, only slightly lower than their own.

And in the process, it effortlessly broke the speed of sound.

Of course, perhaps it was precisely because of this that the location with a relatively large reflective area was exposed that they were able to detect the target in advance.

"This is outrageous..."

Ji Pingfeng had always felt that the J-11B, which had been equipped with domestically produced engines, had become impeccable in terms of maneuverability.

But obviously, there is always someone stronger than you.

In just a few breaths, the two sides, which were flying at a speed exceeding the speed of sound, closed to a distance close to where they could almost see each other.

IRST first detected three signals of skin heating due to supersonic flight.

Immediately afterwards, Ji Pingfeng also saw three inconspicuous black dots with his naked eyes.

Judging from the radar detection results, the other side should have allocated one of its aircraft to deal with the two Su-27s approaching from the north.

Therefore, this is a four-on-three advantageous match.

Moreover, he still occupies a more advantageous height at this time.

However, considering the level of motivation the opponent just demonstrated, these advantages may not last too long.

"Qinling, prepare to engage the enemy!"

He held his breath in his throat to increase his ability to resist the overload.

Then, he led the entire team straight towards the target.

Another less noticeable advantage is that it was already late in the afternoon, so Qinling Team 1 occupied the west side with its back to the sun.

This made Colonel Robinson's eyes react a little slower.

But the performance of the aircraft made up for this time gap.

The seven planes soon started fighting within a range of less than 7km.

In fact, for modern fighter jets, conducting visual range combat at high altitudes over the endless sea is a rather monotonous and boring process.

Especially since this is not a real war, the only sign of victory is whoever is the first to capture the opponent's tail with a camera gun.

Therefore, the most common scene is that the two aircraft fly around each other, trying to see whose energy can no longer withstand the test first and are forced to change from circling to level flight, which is considered as admitting defeat.

In such competitions, the F22 has never been defeated.

The altitude and speed of both sides were rapidly decreasing during the circling, and Robinson soon discovered that although these four aircraft looked similar to the Su-27, their power levels were much better than the latter.

Although he gradually lost his initial energy advantage, he was by no means an opponent that could be defeated in a few rounds.

Especially since the F22 does not have a helmet sight, this makes the simulated aiming process quite awkward.

You have to point the nose of the plane towards the other party.

The colonel gradually lost his patience.

The Flanker is too large and is not a very agile aircraft.

Therefore, he decided to change his strategy first and began to frequently use rolling to consume the opponent.

Sure enough, in just less than half a minute, the opponent who had the numerical advantage gradually showed signs of fatigue.

Robinson was confident that after two more rounds at most, he would be able to catch two of them at an altitude of about 1500 meters, thus completely ending this ugly confrontation.

However, at this split second, a hurried voice suddenly came from the radio:

"Captain Falcon, pay attention to your 240 direction. Four new targets are climbing and approaching at high speed!"

The warning from the early warning aircraft made Robinson's brain buzz.

Looking down, I found that the four targets were within 25 kilometers.

His attention was focused on what was nearby, so of course he had no time to check the monitor.

These new opponents who suddenly appeared had obviously been lying in ambush at low altitude nearby for a long time, just waiting for me to lose my vigilance, fight with the four planes in front until they ran out of energy, and finally enter the scene to clean up the situation in the chaos.

While secretly cursing the Chinese for their lack of martial ethics, the colonel quickly used his mobility to level the battlefield and headed southeast, the only direction without enemies.
