Nine Hundred and Sixty-Four Simple Tasks

In other words, even if the assault fleet sails at full speed, it will take five to seven days to fly over 20 million kilometers.

The assault fleet did not stay in the periphery at all. After entering the orbit around Jupiter, it flew directly to a place 3 million kilometers away from Jupiter before stabilizing and waiting for the arrival of the second fleet.

In theory, the huge satellite group can provide a wide weapon platform for aliens, thus forming a tight seal line from the inside to the outside, making the entire Jupiter impregnable.

However, the distribution range of these small satellites is too far, and the distance between any two satellites is far beyond imagination. Even if the aliens turn all the asteroids into fortresses, it is only a group of scattered fortresses, at most a loose and scattered defense system, not an organic whole.

So there is no need to worry about the small satellites outside. Even if a small satellite approaches, it cannot escape the surveillance of the radar.

The first target of the assault fleet is Callisto, whose semi-major axis is 1.88 million kilometers. The fleet's orbit has moved from 3 million kilometers to 2 million kilometers, and it is still more than 100,000 kilometers away from Callisto's orbit. It can be said to be the preparation stage before the battle begins.

In this way, the criticism of the assault fleet from the rear can be avoided. No matter how you look at it, it is more advantageous to move than to stay where it is.

Ye Han thinks Gao Kai's idea is too utilitarian, but he has to admit that utilitarianism has its reasons. This is probably the reason why people are in the rivers and lakes and cannot help themselves.

Gao Kai agreed with Ye Han's opinion and immediately issued a change of track order to the fleet. Thirty-eight warships of various types adjusted their postures at the same time, facing Jupiter's tail outward, and every four ships lined up in a row to start the main engine and headed towards Jupiter at full speed.

Ye Han originally planned to stop after flying over one million kilometers, tracking Callisto while waiting for the Qiang Er Fleet.

There is a buffer zone of more than 100,000 kilometers. No matter how the aliens react, the fleet has enough time to respond, and it is very convenient to fight or stay.

However, plans are not as fast as changes. Later that day, Ye Han received a communication from Gao Kai: "Ye Zi, I just received a new order from Beidu."

Ye Han suddenly had a bad feeling in his heart: "What's the content?"

"Read it yourself." Gao Kai handed Ye Han a document.

Ye Han opened the order and read the key points at a glance. The general idea was that the interception fleet was about to encounter the alien fleet. Beidu asked the assault fleet to launch an attack as soon as possible to find out the strength of the aliens. It would be best if it could achieve relatively large results and provide reference for the next action of the interception fleet.

To put it bluntly, the interception fleet was about to go to war with the alien warships, but the alien fleet had no intention of retreating. Beidu was a little impatient and hoped that the assault fleet would seize the time and preferably destroy the aliens' nest.

After reading the order, Ye Han frowned: "Where is the Qiang Er Fleet?"

Gao Kai said: "No matter where they are, they can't be relied on."

Ye Han sighed: "Lin Yi, how long will it take to get to Callisto?"

"Sixteen hours." Lin Yi replied quickly.

"Notify the troops to prepare, and don't forget to notify the aliens." After saying that, Ye Han looked at the screen again, "Old Gao, has the observation data come out?"

"It's out!" Gao Kai handed Ye Han another file.

This is the observation data that the fleet has just obtained. The main observation targets are Jupiter satellites with semi-major axes within 2 million kilometers, all within the orbit of Callisto, and the total number is eight.

Ye Han clicked it and said before reading the content of the file: "Fourteen, fifteen and sixteen can be ruled out. They are too small and can't hide much."

Gao Kai's mouth curled up: "The three of them are so close to Jupiter, it doesn't matter if they are there."

"Callisto..." Ye Han quickly found the content he was concerned about, "What does it mean to find several alien buildings?"

"It means that there are only buildings without people, and no signs of alien activities have been found." Gao Kai said.

Ye Han couldn't help rubbing his temples: "There are probably aliens on the fifth, but the orbit is too low, so don't worry about it."

"Then there are only Galileo satellites left, all of which have alien activities,

The situation of one is the simplest. Some alien buildings have been found, and some aliens have been found, but the number is not large." Gao Kai said.

Ye Han simply threw away the documents: "Io is full of volcanoes, and the environment is so bad, it should not have much development value... Forget it, what about Europa?"

"It's about the same as Europa."

"There is so much water on Europa, the possibility of aliens abandoning it is very small, and some people think it is necessary to focus on observation." Ye Han said.

"No problem, it's already being done." Gao Kai took the initiative to say, "Look at the photos of Ganymede. There are the most alien buildings and aliens on Ganymede, and they are very busy. They have placed some white things on the surface. I have contacted the resistance organization, and they don't know what's going on on Ganymede, but I think those things should be anti-aircraft weapons."

"What about Callisto? Are there anti-aircraft positions?" Ye Han looked at the high-definition aerial photos and had an ominous premonition.

"Yes, but not as many as Europa."

Ye Han touched his nose: "Where is the fleet? Have you found any alien warships?"

"No, not a single one." Gao Kai said.

Ye Han was stunned: "Old Gao, do you think the aliens are hiding their true abilities, or did they really take all the warships away?"

"It's hard to say." Gao Kai's expression was solemn, "It's impossible for the aliens to take all the warships away, they must have left some behind, the question now is where are these warships."

Landing is a matter for the airborne division, and the alien fleet is the opponent of the escort fleet. Gao Kai must consider how to deal with the hidden threat.

Ye Han was silent for a moment and suddenly smiled, and he smiled very happily: "No matter where they are hiding in the cracks in the ground, won't we find out after we give them a fight?"

Gao Kai also smiled: "We want to go together again. Let's do a fire reconnaissance first."

"Fire reconnaissance is not enough." Ye Han said, "Even if it is acting, it should be a bit like acting. First, there will be a raid to kill all the ground targets, and then there will be a landing, and first he will send his 8,000 servants up, just in time. Let’s see what the liberals are like.”

No trace of the alien fleet has been found near Callisto. If the alien fleet is hiding on Callisto, then the assault fleet attacking Callisto will definitely force this fleet out.

The orbital distance between Callisto and Ganymede is 810,000 kilometers, and the actual distance is even further. In other words, even if the alien fleet hiding in the dark wants to support Callisto, it cannot avoid the fleet. Based on the observation, the assault fleet will be able to take the initiative no matter whether it leaves or stays.

Of course, it would be better if the alien fleet did not appear. At that time, the assault fleet could directly launch a full-scale attack, directly capture Callisto, and then use Callisto as a springboard to continue the attack on Ganymede.
