PDS, pulse Doppler search, at this time, the AG-9 can only obtain target azimuth information, and no other parameters, in a word, to see if there is a target in the airspace 65 degrees ahead, that's all; Even if a target is found, it is impossible to launch an attack.

It is only used to light the way, and at the same time, it is also the farthest to be found.

Although there is no other information, an experienced radar officer can still judge and estimate based on the direction and speed of the opponent, the direction of the opponent, and the distance traveled by the light spot on the screen.

"I'm afraid we won't be able to set up an interception line before they arrive." Gus said.

They rushed to the airspace of No. 140, and then flew north, facing the MiG-25s that flew in, that was the best situation, but now, the route between them and the MiG-25 group was almost a 90-degree angle, and everyone flew together towards a right-angle position.

Due to the fact that the speed of the MiG-25 was quite high, it was not their turn to fly to the position of the right-angle apex, and the MiG-25 flew over.

What to do?

"Attention 111 Squadron, prepare the Immortal Bird missiles, aim at the target and fire!" Nathan shouted over the radio, "Topol, in charge of directing this interception." ”

With that, Nathan pushed the joystick, and the fighter deviated from its original course and flew to the left.

Just when intercepting the helicopter, he used up an immortal bird, and then he entered the line of sight, and the rattlesnake could do it.

Now, in every Tomcat fighter, there is almost one immortal bird left, which is just right for long-range interception, and after interception, it is time for them to return home.

Apart from the Immortal Bird, there is no other missile that can pose a threat to the high-speed flying MiG-25.

At the same time, their interception will also make the MiG-25 throw a mouse, and maybe it will turn around and return home.

And now, Nathan has left his own formation and handed over the squadron to the deputy captain to command, Nathan certainly has more important things.

Intercept the fish that slipped through the net!

Flying in the current course, Nathan will definitely not be able to fly, so he will fly to the left, that is, in the southwest direction, and in front of the course is his own AWACS aircraft, so that he may get the opportunity to intercept head-on.

Because Nathan walked a diagonal line.

Even if you can't get a head-on interception in the end, you will have a closer distance.

Nathan did not act with his own formation.

The main fighter must be left, after all, his own interception will definitely make the other party throw a mouse, the sooner the interception, the better, there is no need to come over, and what Nathan does, just have a precaution in advance.

If it's the same as I expected, I'm afraid that in that batch of fighters, I'm afraid it's mixed with MiG-31!

If it's just the MiG-25, it's useless to chase the AWACS plane, because the MiG-25's turbojet engine is quite fuel-guzzling, and if he wants to come over, he can only keep driving the afterburner, take off from Sakhalin Island, and fly to the island of Honshu, I'm afraid it's in the stage of running out of fuel, and even if it can launch missiles to attack the AWACS plane, it can't fly back.

At the same time, the missiles carried by the MiG-25 are not good, the range is too close, and it cannot play the role of a sniper early warning aircraft at all, and only the MiG-31 is powerful enough.

Will it be the MiG-31 this time?

Nathan's fighters left their formation and continued to sprint to the southwest, while the other fighters, as the speed of the two sides continued to approach, quickly adjusted to PDSTT mode, ready to launch the immortal bird.

Just when the radar beam switched to locking mode, the radar warning receiver of the MiG-25 fleet was stimulated.

"Oh no, I'm locked!"

"I'm locked in too!"

9 Tomcat fighters locked on nine targets, and at this time, a noisy sound came from the radio, and these locked ones didn't even say the call code.

"038, report locks onto the azimuth source." Andrei shouted over the radio.

After flying over Hokkaido, the radar of the rear base could not play a role, and they could only rely on their own airborne radar to scan the airspace ahead, although the MiG-31's phased array radar was strong enough to detect targets in the airspace ahead, but after all, it could only scan the airspace in front.

Those F-4 fleets have been thrown off by their own side, at an altitude of 25,000 meters, the F-4 can only look up and look up at them to leave, and now, they are about to leave the skies over Hokkaido, at this time they are locked, will it be those F-4 fighters?

If it is them, there is no need to take any care about it, after all, the F-4 fighter can only fire sparrow bullets and has no threat to their own side.

However, this is not necessarily the case with a tomcat.

"038 report, the source of the azimuth is on our left, it's the Tomcat fighter." 038 was still calm.

Only whoever is locked will trigger their own airborne radar warning receiver, and now, although the Soviet technology is backward, this airborne warning receiver has also developed to an omnidirectional receiver.

This kind of receiver has four wideband direction finding antennas installed on the aircraft at 90 degrees to receive the threat radar signal of the illuminated carrier aircraft, and realize 360 ° all-round warning.

Through a series of electronic system measurements, analysis and processing, the technical data such as the working frequency band, signal amplitude, pulse width, pulse repetition frequency, antenna scanning characteristics and signal arrival direction of each threat radar are obtained, and the warning signal is output.

Although it is not possible to use the database to compare and confirm what kind of radar it emitted, the meow in the headset can only be done by an airplane.

Tomcat fighters, on your left side!

Hearing the news, Andrei immediately gave an order: "The locked fighter plane, immediately maneuver to get rid of the locked, and the unlocked fighter plane will continue to fly with me." ”

At this moment, in his rear cabin, Colonel Fedotov, who was specially used as a radar officer for him, finally heard a voice: "I have found the opponent's AWACS plane, just in front of our route!" ”

During this time, Colonel Fedotov has been operating this bulky and cumbersome radar, and now, finally, on the screen, he found that shining point of light, found it!

The target of this visit is the AWACS aircraft of the Americans! Even if this battle fails, as long as the Americans can shoot down the early warning aircraft, they can still take a vicious breath!

"Attention, attention." Andrei continued to give orders on the radio: "The rest of the fighters, continue to sprint for fifty kilometers with me, and then return." ”

The other fighters are all used for cover, and they do not have R-33 missiles on them, so they will not intercept them from a distance.

So, continue to sprint for 50 kilometers, and you can go back, otherwise, I'm afraid they won't run out of fuel!

At this moment, Colonel Fedotov suddenly spoke again: "There are four escort fighters, swooping down on us!" ”

Escort fighters? That's just great, it's delivered to your door!
