Lin Yi's eloquence was average and his speech was not very clear, but he did explain the design concept of the landing ship clearly.
To put it simply, a landing ship is a specially-made rocket transport spacecraft. Its main task is not to send marines to the planet, but to recover the landing team members from the planet!
The Space Marines are not the Marine Corps, and Europa is not a small celestial body with weak gravity. The gravity there is no less than that of the earth. Airborne landing on Europa is very simple, but it is difficult to get the landed team members back into space.
It's difficult.
Without the landing ship, this mission would have turned into a real suicide mission!
In fact, everyone knows that when it comes to the battlefield, it is hard to say whether the landing ship will have a chance to land on the ground. But having such a thing at least has hope of returning is much better than not being able to get back up.
From a certain point of view, the landing ship is indeed a reassurance, but the effect of this reassurance is a bit poor. Ye Han feels that a landing ship must at least be equipped with a pair of rockets. Only one rocket is too much.
No sense of security.
Just do whatever comes to mind. After the meeting, Ye Han immediately went to Gao Kai and told him what he thought.
However, not only Ye Han noticed this, but the fleet's senior officials were also aware of it and made corresponding preparations - in addition to the Yushan, there was another landing ship following the fleet.
And according to the above idea, the two landing ships are also a little short. The troops performing the landing mission should be equipped with three to four landing ships to be safer. However, the fleet is about to set off and there is no time to wait for the new ships to come off the assembly line, so only
I can equip two ships first.
Gao Kai explained clearly, but Ye Han didn't think the two landing ships were safe at all. If he could make the decision, he would definitely delay the fleet's departure until all the landing ships were assembled.
Gao Kai understood Ye Han's concerns, and at the same time assured Ye Han that the Third Fleet would definitely have more than these two landing ships, but the remaining landing ships would have to wait for a while, and the Third Fleet would have to set off first, and the subsequent landing ships would
It will increase power, when to go offline, and when to send out to chase the fleet.
Ye Han still felt that it was unreliable, but for the sake of Gao Kai's words, he had nothing to say.
In the next few days, fleet members returned to the fleet one after another. On February 18, the aircraft carrier battle group headed by the space carrier Nanzhou set sail secretly.
The battle group of the space fleet should actually be called the aircraft carrier battle group, but everyone felt that this term was unpleasant, so the name of the aircraft carrier battle group was used.
There are many people who object to the term "space carrier". They always want to transfer the name of aircraft carrier to space battleship. Some people also call the space carrier a space carrier.
The military doesn't care at all what the spacecraft is called, it only cares about how the battleship performs in the battle against aliens.
After the fleet set sail, the officers and soldiers on the ship were collectively injected with hibernating hormone. Only a small number of people were left on duty on the ship. In order to talk to Bai Xiaoting for a few more days, Ye Han took the initiative to take on the first stage of duty.
The fleet has just set sail and is not far from the earth. The communication delay is very short and basically does not affect communication.
But the duty time was only one week. After one week, Ye Han had to inject hibernating hormone.
The day before the hibernation injection, Ye Han finally received the long-awaited news - a gestational sac was found in the B-ultrasound examination!
But Bai Xiaoting did not tell Ye Han the actual situation, because based on her constitution, the doctor recommended that at least one gestational sac be removed, and preferably two, to ensure the smooth growth of the remaining embryos.
The ovulation induction drugs still had side effects, causing her to become pregnant with three children at once.
Although she was just pregnant, Bai Xiaoting was reluctant to remove any of them. She wanted to keep all three, but she didn't dare to take the doctor's warning to heart. After struggling for several days, she finally removed one of them ruthlessly.
In order to ensure the survival of the remaining two embryos, Bai Xiaoting almost stayed in the hospital and had to consult a doctor no matter what she ate, drank or wore.
Fortunately, she was examined at the military hospital as a military relative, and the hospital knew that her husband was a member of the expeditionary force and took meticulous care of Bai Xiaoting. Otherwise, would she be able to save her two children if she was alone at home?
It's really hard to say.
Time flew by, and it was already late May when Ye Han woke up. After four months of flying at full speed, the fleet had arrived in the middle of the asteroid belt and was about to encounter Europa.
Ye Han woke up together with most of the people. In fact, as early as early May, the bridge officers of each ship had already woken up and were in place. The fleet adjusted its direction in a planned way and accelerated along the planned flight path of Europa.
Both the fleet and Io are moving at high speed. To complete the landing mission, the flight direction of the fleet must be consistent with that of Io, and the relative speeds of the fleet and Io cannot be too different!
In the minds of ordinary people, the relationship between the fleet and Io is very simple. Basically, it is a straight line drawn between the Earth and Jupiter. The fleet and Io are both on this straight line, just like driving head-to-head.
If two cars on the same road want to go together, one of them must slow down and turn around in advance, and then speed up to catch up.
But the actual situation is not like this at all. After the fleet leaves the earth, it seems to fly in a straight line towards the asteroid belt, but the actual flight trajectory is an arc!
Absolute motion is relatively static. To put it figuratively, the flight trajectory of the fleet is like a piece of debris thrown from the earth, leaving a parabola in the universe.
This is hard to understand. To put it in a simpler way, the positional relationship between the earth and the fleet is equivalent to a skydiver throwing something horizontally!
People and things are falling, and the distance between them is getting farther and farther.
The situation of Io is similar. It is like Jupiter throwing something towards the earth. It looks like a straight line when flying towards the earth, but the actual flight trajectory is also an arc!
The result of this situation is that the fleet and Jupiter appear to be heading head-to-head. In fact, they are more like two cars getting closer and closer at a Y-shaped intersection. Therefore, the fleet only needs to adjust its direction in time to cut into Jupiter.
The flight trajectory of the Guardian Zero does not require slowing down in advance and then turning around and accelerating as ordinary people think.
The situation is a bit complicated. In short, the fleet is gradually approaching Europa. When Ye Han wakes up, there are only five days left before the expected encounter between the two sides.
As soon as all the officers and soldiers woke up, they began intensive preparations for combat. The first task was to check all the weapons and equipment on the ship and other equipment.
At this time, the distance between the two sides is already very close. Not only can I see Europa in the telescope, but I can also see the alien fleet guarding Europa and the international fleet that is lingering!
