963 Orbit change

Ye Han suddenly turned around: "How is it possible?" His movements were so violent that his body floating in the air almost lost control.

When the fleet departed, everyone thought that the assault on the fleet was just a formality, and that the alien fleet could be successfully retreated by forcing the alien fleet to return.

But reality made a big joke, the alien fleet did not retreat at all, and the raiding fleet was ...... at once No, it's forcing the entire human world into a corner.

Out of the sensitivity of the profession of a soldier, Ye Han thought more.

The raiding fleet not only did not hide the purpose of the trip, but swaggered forward, and it was impossible for the aliens not to see it. But the alien fleet just won't turn back, so does it mean that the aliens have confidence in Jupiter's defense level and think that the assault fleet is no threat?

Or is it that the aliens have gathered enough strength and don't want to stay in this hellish place, intending to conquer the earth in one fell swoop?

Well, there are a lot of enemy warships in that army, but it is definitely not overwhelming, the probability of defeating the combined fleet is very low, the probability of occupying the earth is even lower, and the counterattack on Ganymede is almost ......

Thinking of this, Ye Han suddenly had a wit in his heart, could it be that the target of the aliens is really Europa?

Lin Yi didn't know what Ye Han was thinking, so he silently handed over the tablet, Ye Han took it and swiped his fingers, and quickly found the most critical words.

He was not in the mood to look down a little bit, so he casually returned the tablet to Lin Yi: "What do you mean by Beidu?" Continue or return? ”

Lin Yi hurriedly replied: "The above means to continue." ”

Ye Han sighed faintly, put his arm on his hand, turned back and continued to look at the screen.

What does it mean to continue?

Taking advantage of the absence of the main force of the aliens, they copied the aliens' lair? Or is it a test of how much power the aliens have retained?

"When does it start?" Ye Han asked again.

"The sooner the better."

"Where is the Second Fleet?"

"There are still two days to go, and it is expected to arrive on the 22nd."

Ye Han's eyes were clouded with a layer of haze, it was said that the strong second fleet should arrive at Jupiter at the same time as the strong attack fleet, but he didn't know how to slow it down for two days.

In other words, two days is nothing in normal times, but in a rapidly changing battlefield, two days is enough time to determine the success or failure of the entire campaign.

He couldn't help but wonder again whether the two days behind the Second Fleet was intentional or unintentional.

Lin Yi waited for a while but didn't wait for Ye Han's order, and couldn't help but ask, "Chief, shall we fight or not?" ”

Ye Han said without looking back: "Fight, you must fight." "Beidu didn't expect to strengthen the second fleet, and the two fleets also fought separately in the plan, the only thing to worry about is that the number of fleets is less than half, and the deterrent effect to aliens is too small.

This is an alien lair, can the assault fleet scare the aliens?

Hard!

"When will you hit then?" Lin Yi asked again, "What about the Nanzhou and other letters." ”

The task of attacking the fleet is relatively special, so it is divided into two parts, and the fleet is commanded by Gao Kai, who is mainly responsible for intercepting the alien fleet...... The reason why he was sent here was that only the Second Expeditionary Force was successful in all the expeditions.

The command of the landing was completely handed over to Ye Han, and when it came to landing, Ye Han naturally had the right to decide, and he could decide whether to continue the mission according to the actual situation, and even Gao Kai had to listen to him.

This mission revolves around landing, and Gao Kai can't listen to it if he wants to, so Lin Yi asked this question.

Ye Han thought for a while and said, "How many days do the interceptor fleet have to catch fire?" ”

On the screen, a helicarrier is docking with a destroyer, and in fact an integrated supply ship is docking with a transport ship full of aliens to replenish the transport ship with food and air.

This happens every twenty days or so, but this is the first time I've seen it in person...... Ye Han's mind turned to the resistance organization again, he hadn't figured out how to use this force until now, but he vaguely felt that the method of divisional combat was not very good.

Lin Yi couldn't see Ye Han's expression, and replied to himself: "There is no detailed timetable, about a week." ”

"Seven days ......" Ye Han muttered, making up his mind, "We'll wait here." ”

In seven days, two fleets were about to take fire...... At this point, even if the assault fleet smashed Jupiter to pieces, it was impossible for the alien fleet to turn back, and it was only a matter of time before the two fleets exchanged fire.

In this case, whether the raiding fleet is a few days earlier or a few days later has no effect on the result, and since this is the case, there is no need for the raiding fleet to mine the second fleet.

Knowing what Ye Han meant, Lin Yi immediately said, "I'll transfer your meaning to Nanzhou." ”

"No, I'll do it myself." After saying that, Ye Han was going to communicate with the Nanzhou, and Gao Kai's bust appeared in the corner of the screen, "Old Gao, let's wait for two more days." ”

Gao Kai pursed the corners of his lips: "I know." "Yezi, I suggest starting now." ”

Ye Han sighed, told Gao Kai his analysis, and finally concluded: "So I think it's best to wait for two days." ”

Gao Kai said: "I understand your thoughts, but you say, how much does the earth understand?" If we really stick here, we don't know how many people will steal the knife. ”

"Then what do you mean......" Ye Han's brows froze.

He considered the problem purely from a military point of view, but when Gao Kai considered the problem, he also added political issues, although Ye Han was reluctant to admit it, he felt that Gao Kai's consideration was more comprehensive.

Outside, the king's order is not affected, but after all, it is really strange that he is not affected!

After launching the attack, the specific tactics are better to say, at the critical juncture when the interception fleet is about to collide with the alien fleet, waiting for several days for the strong second fleet, not to mention public opinion, even within the military, I am afraid that there will be discordant voices.

Gao Kai said: "At the very least, you have to make some moves, and you can't wait in this ghost place." ”

Ye Han nodded thoughtfully, thought for a while and said, "Otherwise, the fleet will immediately start to change orbit and move to two million kilometers first, what do you think?" ”

At present, the fleet is more than 3 million kilometers away from Jupiter, and the orbit change distance of more than 1 million kilometers is difficult to say whether two days is enough.

The position of the fleet was not chosen randomly, but for a variety of objective reasons.

Jupiter has many moons, most of which are relatively small in size and mass, and far away from Jupiter, with the vast majority of moons having a semi-major axis of 20 million kilometers away.

20 million kilometers is just a number on paper, but in the real world it is not like that.

Because it is five million times the circumference of the Earth's equator; fifty-two times the distance between the Earth and the Moon; One-third of the distance between Earth and Europa!
