965 Airstrike on Jupiter 4

May 22, 2030, the bridge of the Nanzhou aerospace carrier.

There was no extra noise in the bridge, and all the bridge officers were on high alert.

At this time, the assault fleet was near Callisto, and was moving parallel to Callisto at a distance of one thousand kilometers - this distance was very close, but far beyond the range of alien weapons.

The Qiang Er Fleet had arrived at Jupiter not long ago and was changing its orbit to a low orbit, but the orbit change would take two to three days, and the assault fleet had no time to wait any longer.

The assault fleet was ready for battle, with all the warships rushing outward with their tails and their bows aimed at Callisto, and the ground-to-air war was about to break out.

At ten o'clock in the morning, Gao Kai broke the silence: "Let's get started."

"Begin the action!"

The combat staff quickly passed the order down, and the order was passed to the Yaoshan, and a voice shouted loudly: "Start the electromagnetic gun on the port side-"

At the same time, the machinery in the gun compartment was running, and the mechanical arm inserted a wrist-thick tungsten alloy rod into the gun barrel. Then the current was connected, and the lightly suspended metal rod was immediately bound in the air by an invisible force.

"Fire--" At the flagship's command, the metal rod was immediately sent into the barrel by the invisible electromagnetic force. After continuous acceleration by the magnetic force, the metal rod weighing 50 kilograms was ejected at a speed of 6,400 meters per second!

The port gun had just finished firing, and the starboard gun immediately took over, and another round of salvos.

In this way, the electromagnetic guns on the left and right sides took turns to appear, and the 23 warships fired more than ten rounds in a row before stopping at the flagship's command.

The electromagnetic gun is the latest equipment of the space fleet. The aerospace mothership, destroyer, frigate and assault ship are all equipped with one on each side, and the supply ship has only one. As for the transport ship handed over to the resistance organization, let alone the electromagnetic gun, there is no close defense gun.

On the bridge of the Yaoshan ship, Ye Han looked at the main screen silently, and suddenly remembered the memory of the first time he saw Callisto.

At that time, Callisto was like the moon, with craters full of pits and valleys, and it looked desolate no matter how you looked at it.

Today, Callisto has changed a lot in the hands of aliens. Many of the originally uneven places have been flattened by aliens, and many ice-white alien buildings have been built.

Ye Han glanced at the time and felt a little emotional. It is now 10:02:25. In another 11 seconds, the first wave of shells will fall on Callisto. And this is only the first round of bombing. There will be rounds after rounds until all the buildings on the surface of Callisto are destroyed.

A little light suddenly burst out on the surface of Callisto, but it disappeared immediately. Ye Han glanced at the time, exactly two minutes and thirty-six seconds.

Then the surface of Callisto seemed to be boiling, with fleeting lights everywhere. Those lights were so inconspicuous, just like a batch of low-quality fireworks being set off.

However, if you zoom in, you will see that every flash of light will shatter everything nearby, the buildings will collapse, the ground will sink, or leave a crater with an astonishing diameter.

According to Ye Han's experience, the power of each tungsten alloy shell is no less than that of a large-caliber shell. However, the senior officers of the fleet who witnessed this scene all frowned.

A 50-kilogram tungsten alloy shell is indeed a little lighter, and it is normal that its power is not as strong as that of an asteroid impact, but the actual strike effect seems to be far from the theoretical calculation result, which is puzzling.

The calculation result cannot be wrong, so is it a design problem or a principle error?

Fortunately, none of the senior officers of the fleet are stubborn and stubborn. It doesn't matter if the effect is a little worse, as long as it is not ineffective.

So Gao Kai ordered the second round of air strikes without hesitation, and specified that the depleted uranium warheads should be replaced with tungsten alloy warheads.

The electromagnetic gun is equipped with two types of warheads. The tungsten alloy warhead is large in size and heavy in weight, with a muzzle velocity of about six to eight kilometers per second, and is generally used for ground attacks; the depleted uranium warhead is much lighter than the former, with a muzzle velocity of more than 10,000 meters per second, and is mainly used for warship confrontation.

Depleted uranium bombs are too light, and using them to bomb the ground will not be more effective than tungsten warheads.

But no one in the entire fleet asked a single question, and all the warships participating in the air strike immediately followed suit, and in the blink of an eye, several rounds of depleted uranium bombs were dropped.

More than a minute later, several light spots exploded on the surface of Callisto, and both the brightness and duration were much stronger than tungsten warheads.

This phenomenon attracted Ye Han's attention. He knew that depleted uranium could generate high temperatures and self-ignite when hitting a target, but the thin atmosphere of Callisto was mainly composed of carbon dioxide, so where did the phenomenon of depleted uranium bombs hitting the target come from? Could it be the oxygen stored by aliens?

Otherwise, the depleted uranium bomb penetrated the ceiling of the underground building...

The target of each shell was not chosen randomly. During this period, the fleet observed Callisto 24 hours a day. A few days ago, aliens could be seen roaming around on the surface of Callisto, but after the fleet arrived, all the aliens disappeared. It was obvious that they hid underground, and their routes and positions when they hid were kept in the fleet's observation records, which just provided a target reference for the bombing.

The second round of bombing ended, and the effect was indeed not as good as the first round. Gao Kai did not say anything, but just whispered: "Did you find anything?"

"No." Lu Zuo replied softly.

Gao Kai's facial features were squeezed into a ball: "The war has started and they still haven't come out. What the hell is going on?"

The assault fleet has been hovering near Callisto for a while. The alien fleet should have appeared long ago, but the shells have all landed on Callisto, and still no alien warship has appeared. This strange situation really makes him worry.

Lu Zuo said: "Commander, I am worried that Callisto is a trap. Maybe the aliens are afraid that we will run away and are waiting for us to land. If we can't run away, it will be troublesome."

He is not afraid of the enemy being exposed. The space is so big that there is no cover or blockage. In addition, the speed of human warships is not inferior to that of alien warships, and there is a clear advantage in long-distance travel. If they want to leave, the aliens can't stop them at all.

Gao Que smiled slightly: "Ye Han is thinking the same as you."

"The next step..." Lu Zuo deliberately said half of the sentence to leave Gao Kai a question.

Gao Kai said: "If the aliens don't move, we will move. Change the track and get closer to bombard him a few more rounds."

"To what position?" Lu Zuo asked.

Gao Kai's eyes showed a hint of determination: "About 700 kilometers, let's do a targeted elimination and see if the aliens can keep their cool."

When Lu Zuo heard this, he couldn't help laughing: "Change track, change track, 700 kilometers!"

He couldn't help laughing. The effective range of the thin light was between 600 and 700 kilometers. The anti-aircraft firepower of Callisto would definitely not reach the fleet, but the firepower of the fleet could bombard Callisto without being affected. It was just taking advantage without suffering any loss!
