Red Soviet Union

The Soviet Mars probe successfully landed on Mars, which has cross-epoch significance, because the time it took for this landing was only one-tenth of the normal time!

However, this news did not cause too many waves in the world. At this time, the eyes of the whole world are focused on the Middle East and the Mediterranean Sea. At this time, an unprecedented war is breaking out!

Due to the provocation of the U.S. Navy aircraft carrier formation, the Soviet Navy launched a counterattack against the U.S. Navy without hesitation. The two Glory-class cruisers fired 32 anti-ship missiles, forming four huge formations, heading towards the direction of the U.S. Navy flight!

Facing this batch of missiles, the U.S. Navy made an emergency response. The first batch of intercepting forces was the pride of the U.S. Navy, a combination of panda fighters and phoenixes!

Although the navy's maintenance and maintenance of the Tomcat fighter has gradually felt powerless, and it has to use the f-18 to replace the Tomcat fighter. However, the Tomcat fighter is the only fighter of the US Navy with multi-target interception capabilities. Therefore, the Navy The improvement of the Tomcat fighter did not stop.

For example, half of the Tomcat fighter jets on the Eisenhower aircraft carrier have developed into the F-14D type. Compared with the original model, the biggest feature of this fighter jet is that it uses the APG71 radar instead of the AWG-9 radar.

When it comes to the awg-9 radar, it is definitely famous. During the entire cold war, the combination of this radar and the phoenix was simply invincible.

However, this kind of radar actually has flaws. For example, most people know that Soviet radars are big and thick, and quite heavy. In fact, the awg-9 radar is also heavy. With a diameter close to 1 meter and a weight of more than half a ton, this large airborne fire control radar, in the pds mode, has a maximum detection distance of more than 300 kilometers for targets such as strategic bombers. At that time, it was indeed against the sky.

However, in other aspects, there are also great flaws. For example, the average time between failures is less than one hour. This kind of radar requires constant maintenance, and at the same time, it consumes a lot of power.

So, Hughes produced the AN/APG-71 radar, which is an improved version of the AWG-9, but uses technology from the APG-70 radar in the US Air Force's f-15 Eagle multi-stage improvement program, and the radar antenna itself It is an antenna with low side lobe radiation, and it can filter out the interference wave entering from the side lobe, plus it can use a single pulse for accurate angle tracking, so the anti-interference ability is very strong.

At the same time, this radar has improved the frequency modulation mode of its Doppler ranging signal, which makes it have better resolution for ground noise. Change the low pulse repetition frequency of awg-9 to medium prf, which has a better performance in locking the head-on air targets and can measure more accurate distances.

It is an exaggeration to say that this kind of radar can measure the number of engine compression blades of the head-on target, and then know the engine model and aircraft model. It can be said that it is absolutely abnormal.

At the same time, the maximum transmission power of this radar is 5 kilowatts, which is only half of the AWG-9, but the maximum search distance has increased instead.

It can be said that the biggest feature of this radar is the digital improved model of the awg-9 radar, which uses the new high-speed digital signal processor of the apg-70, digital scanning control, and its processing capacity is six times higher than that of the awg-9.

If it is the previous awg-9 radar, it is still difficult to intercept supersonic flying targets, but the current apg-71 radar can easily intercept incoming supersonic anti-ship missiles, and you can even try Intercept some short-range ballistic missiles!

Now is the time for the apg-71 radar to show its abilities!

Of course, whether the interception can be successfully intercepted in the end also has a lot to do with the operational ability of the radar operator in the back seat. The radar officer quickly tracked the target and switched to the locked state. Then, the flames under the wings were blazing, and two Phoenix missiles, Just fly over!

If it is a head-on attack,

The respective speeds are Mach 2, so the relative speed is Mach 4! This must be able to keep up with the data processing system!

And now, the new apg-71 radar is enough to complete this task!

Although the Phoenix missile is an active missile, this is only the last stage! Now, relying on the radar of the carrier aircraft, after the Phoenix missile is launched, it is flying smoothly along the interception trajectory.

The target missile didn't seem to feel the imminent disaster, it continued to fly smoothly, as if waiting for those Phoenix missiles to kiss them passionately.

The ramjet engine continuously inhales air, ignites the fuel, and ejects high-pressure exhaust gas. The speed of the p-500 missile is further increased, reaching Mach 2!

The distance between the two sides is rapidly approaching, 50 kilometers, 40 kilometers, 30 kilometers... The Phoenix missile launched first is even less than five kilometers away from the target!

Interception is about to succeed!

However, at this moment, suddenly, all the p-500 missiles on the sea made a maneuver in unison!

First to the right, then to the left, they made a beautiful s-shaped maneuver on the sea!

Damn it!

For a Mach 2 target, a snake-like maneuver is enough to temporarily unlock many radars!

When performing s maneuvers, they will fly to the radial direction of the radar, and they will be filtered out as clutter! This is caused by the characteristics of Doppler radar. If it is not filtered out, the clutter flying all over the sky will overwhelm their processors!

But now, the other party only released the lock for a short time, and after a while, it appeared in the radar's field of vision again.

It's just that this has already caused irreparable consequences!

Relative speed four Mach! Even if the target is only lost for a second, the relative distance will change by more than a thousand meters! And to re-intercept the target and recalculate the interception trajectory, this will waste the reaction time of the phoenix!

After all, many phoenixes have entered the final active interception process, and the onboard computer of the phoenix is ​​definitely not as powerful as the onboard computer of the Tomcat fighter!

As a result, the Phoenix missile, while still flying along its original trajectory, had already passed the target. In front of it, the airspace was clear and there was nothing!

Of course, not all of the phoenixes got rid of them, and the two phoenix missiles aimed at one, and some, managed to hit the target!

boom!

Following the violent explosion, the phoenix successfully shot down the leading p-500 missile at an altitude of 6,000 meters!
