After some open and secret fighting, the northern capital finally retreated under pressure from all sides, and in early April 2030, the combined fleet left the port and departed.

The total number of warships of the combined fleet is more than 100, of which 55 warships were dispatched by the Beiyuezhou fleet.

Among the more than 50 warships sent by the Chinese side, five large aerospace carriers; Eighteen destroyers and thirty-two frigates, a proper capital ship group.

Despite this, the outside world is still very dissatisfied with the decision of the Northern Capital, because the Northern Yuezhou Fleet has twelve aerospace carriers, in addition to the four taken away by the Raid Fleet, there are as many as eight, but there are only five in the Combined Fleet, and three are always in their pockets.

Foreign media believe that the earth is already at a critical moment of life and death, and preserving strength at this time is simply death, and Beidu, as the largest space country, has the strength and responsibility to invest all its armed forces to stop aliens.

Even in China, there are a group of people who think that it is useless to leave a few space carriers.

This view cannot be said to be wrong, if the combined fleet fails, the three aerospace carriers retained by the northern capital will not be able to pick up the girder at all, and it is better to put all of them into the combined fleet and fight together.

The total number of warships in the combined fleet is more than 100, and there are more than a dozen space carriers alone, which can be said to be the most powerful fleet in the history of mankind.

In desperation, Beidu had no choice but to announce the truth to the outside world, and it was not that these three aerospace carriers did not want to be sent out, but that they could not make the trip for various reasons.

There are many specific reasons, and Beidu has also explained in detail:

Only one of the three aerospace carriers is intact, but due to a mistake in the coordination of materials, it has not been equipped with enough carrier-based aircraft, and in addition to the serious lack of pilots, it has not been able to carry out the mission in a short time.

The other two seem to be complete, but in fact, one has just come off the assembly line, and the equipment has not yet been installed in place, so it is inseparable from the dock at all; The other had a minor accident not long ago, destroying two thrusters and had to be repaired before it could be operated.

The reason is very strong, the outside world doesn't know whether it's true or not, in short, it can't be investigated if you want to, no matter what kind of speculation and slander, it can't shake the determination of Beidu.

In fact, there are not three aerospace carriers in the pockets of the northern capital, but a full six of the three major ones, this is because only the Nanzhou is real among the four aerospace carriers in the assault fleet, and the other three are comprehensive supply ships disguised as aerospace carriers!

However, the shortage of carrier-based aircraft and pilots is indeed real, but it is not as serious as it is publicly advertised.

When the combined fleet departed, the aircraft factory in Beiyuezhou was organizing surprise production, and the pilots were also training intensively, and the military even lowered the training standards for pilots in order to fill the vacancies in a timely manner.

Originally, there should not have been such a low-level mistake, originally there were enough carrier-based aircraft and pilots to fill all the Aerospace Carriers, but some time ago, the Northern Capital carried out automated modifications of all warships, and the Aerospace Carriers were no exception.

One of the key points of the modification is to replace all carrier-based aircraft with unmanned remote control models, so that pilots do not need to sit in the cockpit of carrier-based aircraft, but only need to sit in the remote control cabin of the carrier ship to operate the corresponding aircraft.

In addition, the military has made corresponding improvements to carrier-based aircraft, and the number of aircraft carried by the aerospace carriers has been greatly increased, and the result is that the aircraft, which was originally enough for twelve aerospace carriers, ended up only filling six warships.

However, the military is making up for the gap, and it will not take long for a steady stream of carrier-based aircraft on the production line to fill the battleship and the pilots to be in place in time.

Limited by the training time, the overall quality of this batch of pilots will definitely be weaker.

Not only the aerospace carriers, but also a number of destroyers and frigates have not been sent, and there are also some objective reasons for the northern capital to cover these warships, one is the lack of crews, and the rookies who have not completed the training will not only fail to form combat effectiveness, but may also become a drag; Second, the weapons and equipment are insufficient, the military concentrates all nuclear weapons on the departing warships, without nuclear weapons, it is difficult to fight against alien warships with conventional weapons alone, it is better to keep a back hand in Beiyuezhou.

It is said that the moon produces a large amount of helium-3, and the space fleet should not lack nuclear weapons, but helium-3 is not so simple, it is a noble gas that is difficult to liquefy, its properties are difficult to combine with other substances, and the reaction conditions of rare compounds are also very harsh, and helium-3 cannot be turned into a solid substance by chemical reaction.

Moreover, helium-3 fusion requires more energy and produces less energy, which is nothing to use in fusion reactors, but it is somewhat chicken when used in nuclear weapons.

In addition, the reaction conditions of helium-3 fusion are too harsh, and considering various factors, a pure helium-3 nuclear warhead is neither economical nor affordable, and it cannot be done at all with the current technological capabilities of mankind.

Therefore, for a long time, human beings can only engage in the second-generation fusion of deuterium and helium-3, and the number of nuclear warheads has always been limited by the production of deuterium, and it is not that with helium-3, nuclear bombs can be infinitely exploded.

Another very important factor is that nuclear power engines consume a lot of nuclear materials!

All in all, human beings have a large production and consumption of nuclear materials, and they are not as abundant as ordinary people think.

On May 12, 2030, the interceptor fleet flew through the orbit of Mars, and the two sides traveled in the same direction, getting closer and closer.

All the countries and people of all the countries on the earth have their hearts set on the interception fleet, and the most important thing every day is to care about the situation of the interception fleet.

However, the general public did not wait for the news of the exchange of fire between the interception fleet and the enemy army, but waited for the news that the raiding fleet had arrived at Jupiter!

May 20, 2030, Yaoshan.

The raiding fleet arrived near Jupiter and slowed down to cut into its orbit around Jupiter, but did not change its orbit to a low-altitude orbit and remained at a distance of more than 3 million kilometers from Jupiter.

This was the third time in Ye Han's military career that he was close to Jupiter, and looking at the quietly rotating red giant planet on the screen, his mind couldn't help but think of the experience of two expeditions to Jupiter.

One failed and almost died, and the other official propaganda succeeded, but in fact there was no result...... What was the final result of the third expedition to Jupiter?

"Chief!" Lin Yi softly interrupted Ye Han's thoughts, "There is news from the Nanzhou." ”

After the fleet recovered, the first thing to do was to contact Earth and ask about the situation in the past few months.

Ye Han tilted his head slightly, his eyes still staring at the main screen: "What did you say?" "The Yushan has been nailed to Ganymede, Ye Han thinks this kid is good, it's a pity to throw it on Ganymede, and he specially asked him to come over to serve as the captain of the Yaoshan.

Lin Yi took a deep breath: "The flagship reported that the alien fleet has not returned yet, and the interception fleet has been about to exchange fire with the enemy, and there will be a few more days at most." ”
