Under such a battle, the headquarters of the planet 439 withdrew, and the last 100 attacking motherships were left. There were only a cluster of less than 30,000 drone fleets left in the sky.

They were still in front of the speech, and a large number of missiles were fighting desperately.

If the drone has no emotions, they will not worry, fear and sadness their teammates abandon themselves.

The purpose of these drone clusters is to block these missiles and use their last body to block the missile's attack.

Help your attack mothership evacuate immediately and return to the planet headquarters to implement supplements.

However, attack missiles cannot enter the atmosphere. They can be launched in the atmosphere. However, they cannot pass through the atmosphere.

For the 439 planet, the drone fleet of the Expeditionary Force is not afraid of. It will launch active attack missiles from outside the planet into the atmosphere.

The drone cluster of the Expeditionary Fleet also arrived at the planet, with a close distance of 180 kilometers.

Now the attack missiles have swept across the entire planet, and the last remaining power of the drone fleet sent here.

The fleet of 200,000 planet drones was destroyed and the losses were completed.

The Expeditionary Force's drone fleet began to surround the planet, above a 180-kilometer range. This range is basically the edge of the planet's inner air defense strike.

There is no way for the ground air defense system inside the planet to carry out air defense strikes over this distance.

Therefore, 500,000 drones formed a huge encirclement at this location. The reason why they are still 500,000 drones is mainly because the drones in front have not actively participated and actively attacked missiles to attack the opponent's drones.

Fleet combat activities.

Then 500,000 drones formed a huge outer encirclement for the 439 planet, a range of about 230 kilometers from the planet.

This is the most common number of low-Earth orbit used by the Expeditionary Forces, because the number of low-Earth orbit on the Earth is between about 200 and 300 kilometers.

More than 200 kilometers is a normal interval number in the middle. After forming an encirclement circle, the second is the attack of the joint fleet, the mothership fleet and the auxiliary fleet.

He also came from behind and hid behind the drone fleet's defense line. Lin Dong then ordered the rear of 5,000 giant launchers and forward road line to carry out intensive missile attacks on the planet's headquarters.

5,000 open interstellar launchers moved slowly to the second line of defense. This line of defense consisted of about 1,000 attacking motherships, and there were 1,000 independent warships as escorts.

The launcher then began to carry various types of attack missiles, locking the target through satellite scanning.

The detection satellites used by the Expeditionary Force are unmanned probes. They can perform orbital detection scans or time-travel scanning. But no matter what, the planet 439 must be taken down.

Otherwise, Lin Dong's main fleet would not be able to cross the narrow passage, and it would be even more impossible to fly around more than five light years.

The missile launcher is already covered with various missiles. The open and generous group launches can be carried out, just like rocket launchers.

Because they are launching in space, there is no need to care about the so-called load-bearing recoil issue.

The 3,000 missile launchers can be launched at one time, and various types of ground-to-ground long-range attack missiles are about 3 million. The launchers can carry and store 3,000 missiles per week.

1,000 missiles can be launched at one time. It can launch Mr. Jia, with a sufficient ammunition base to launch three times. The dense missile attack waves are attacked.

The ground targets hit by long-range missiles are mainly ground airport production centers and communication center supply bases. At the same time, there are defensive fronts, mainly air defense defense fronts.

This time, Lin Dong attacked the ground airport and the supply center. Because he knew that 200 assault motherships were loading drone systems on the ground and eliminating these 200 attacks.

Hit the mothership. Then the other party loses the space barrier.

Originally, the missiles were already ready to be launched, but Lin Dong suddenly ordered the missile's attack target to be adjusted.

The fleet immediately transformed the missile's attack target into an attack communication center, a central command and control base, an air defense front, instead of attacking the 200 attacking motherships loading drones.

Then 1 million US long-range attack missiles flew towards the planet's headquarters cluster.

They started from multiple angles and the impact entered the atmosphere. Long-range attack missiles were multi-warhead attacks. Once they entered the atmosphere, they immediately began to conduct division and guidance.

Ground anti-aircraft artillery immediately began to intercept violently. This was all necessary work. And 1 million long-range attack missiles.

This amount is also sufficient to withstand the interception of dense artillery fire and air defense missiles on the ground.

Generally speaking, only about 30 to 40% of attack missiles can enter the atmosphere at most.

The rest will be intercepted and destroyed by air defense fire. So about 300,000 long-range attack missiles entered the atmosphere.

Then they implemented sub-guidance guidance at a height of 40,000 meters in the atmosphere. 300,000 missiles, each missile can carry ten warheads.

Then after they were divided in the air, they were 3 million warheads. The warheads had guidance devices on their own. At the same time, they contacted the parent body through long-range optical cables and callback systems.

The parent body will have a node drifting in the air. This node is like a hub station. It can provide auxiliary guidance and auxiliary target guidance to the sub-warhead.

Even if you destroy this node, the sub-warhead will still fly towards the target Zhu Yuan according to the already entered target and strike the target.

To intercept these 3 million, if there is no single head, almost all the air defense firepower on the planet is concentrated. Although it is in the atmosphere, it is impossible to use human fighter jets to intercept such attack weapons.

As the warhead fell, the drone began to compress its outer defense line and advance towards the internal distance of the planet's headquarters.

Because now all the anti-aircraft fire and anti-aircraft artillery on the planet Sanjiu are mobilized to attack these sub-missile heads. So they have no remaining strength and then go to protect the space defense line.

In this way, the empty spot built by the space house gave the drone fleet an opportunity to take advantage of. Then, the drone fleet began to enter the atmosphere. Once the drone fleet entered the atmosphere.

Then the entire planet will face fierce attacks from 500,000 drones.

By then, the planet 439 will take off and about 5,000 humanized fighter jets will be launched. This is the kind of war that Lin Dong least wants to see, which is to use his drone to map the humanized fighter jets of his compatriots.

Because the huge fleet of drones exceeds 500,000. Faced with only a few thousand manned fighters, no matter how superb or smart aviators are, they will be difficult to withstand such a comparison of air combat.

Therefore, the drone cluster soon completely eliminated the manned fighter troops rushing up in the air. About 4,000 manned fighter jets were shot down in the cluster.

The drones also lost at least about 150,000. However, this has no meaning to the drones, because there are 3,000 attacking motherships in the space behind them.

The second line of defense formed. These attacking motherships immediately ejected 500,000 drones like the main body of the planet.

With the remaining number of drones in the last wave, the number of drones increased from 500,000 to more than 800,000.

Even if another 5,000 fighter jets were dispatched on the surface of the planet, facing a cluster of 800,000 drone flying all over the sky, they could only sigh or feel sad and suicidal resistance.

Sure enough, the 439 Command sent about 8,000 manned fighter jets from the ground. This may be the last batch of manned fighter jets on this planet.

So 800,000 drones began to surround them.

Manned fighter jets carry out attacks. The intelligence level of drones is also very high. They know that there is no need to siege these manned fighter jets 1 to 100.

So about 200,000 to 300,000 drones were transferred away. They turned around and flew towards the ground and rushed directly to the air defense system on the ground. The current air defense system is working hard to fight the sub-missile heads.

There is no time to take into account the attacking drones. If you rely on the individual air defense system on the position or the temporary maneuverable air defense system, the height of the drone is not too good.

However, drones can use parachute ejection to carry out precise strikes on the ground at an altitude of 8,000 meters.

They also have precision guided bombs propelled by rockets. This kind of bomb is propelled by rockets, which quickly advance from 8,000 meters to an altitude of about a few meters. It can be used for air explosions or directly landing and explosions.

Such a 300,000 drone launched about 1.2 million, including ground-attack missiles and rocket-mounted bomb-loaded weapons.

The ground-attack missiles quickly rushed towards all air defense systems. Some air defense systems could only adjust the muzzles and aim at these ground-attack missiles.

They have clearer targets than warheads, and they are attacking these air defense systems.

One of the most critical factors is the lack of air-defense weapons like war fortresses.

And like the Expeditionary Force, there is also a kind of air defense mecha, which is mainly configured for the army to use to defend against the Air Force strikes.

After this battle, the entire ground air defense fire system was basically destroyed by missiles and rocket bombs launched by drones.

The ground air defense system was destroyed, and the warheads on it began to fall down after that.

The attack energy of the warhead is much greater than that of missiles and rocket bombs.

A warhead landed on the attack line. It can almost blow away 2/3 of the ability of this attack system.

Soon, almost all the air defense system on the surface of the planet, plus the communication center, command and connection mechanism, were destroyed by the Air Force's strike.

439's air defense system was completely paralyzed and had no resistance.

On the ground 18 air port, 200 large attack motherships are replenishing drones there. Although this method of replenishing drones is also an automated transmission method.

However, the replenishment speed is very slow. Moreover, the attack mothership can carry 1,000 drones every week.

So such a good thing takes at least three or four hours. During this period, the attack on the mothership has no ability to react or resist.

Lin Dong wanted this opportunity. He wanted to collect 200 attacking motherships as a basis for replenishing the new team and then undergoing transformation.

Now her war ideas have basically changed completely. After destroying the opponent's air defense system, Lin Dong's various strange engineering motherships can enter the inside of the planet.

In fact, once they enter the inside of the planet, no matter how powerful the ground inside your planet has, in the future.

If the expeditionary force wanted to do it, the war would basically end. After the engineering mothership entered the planet headquarters, it began to fly at the locations of 18 ground airports.

Their purpose is to use frozen light beams, that is, frozen light speeds, over these 18 airports. They can freeze irradiate the attack mothership that is being replenished in the neutral gear.

In this way, the 200 attacking motherships were sold. The 439 Command was forced to order the blow-up of these attacking motherships. The Expeditionary Force could not obtain these supplementary equipment.

He knew very well that these attacking motherships would immediately rejuvenate their youth once they reached the hands of the expeditionary force.

However, all the automation systems they can use now have been paralyzed. They can only send humans and troops to the mothership to start the self-destruction device.
