One Thousand Eight Hundred and Sixty-One Space Defense Network

Ye Han was in a bad mood. The situation on the ground had just seen the light at the end of the tunnel. How could Wu Han think that the situation in space was very bad?

Wu Han sighed, "Have you learned about the situation of the expeditionary force?"

"I don't know. There has been no news."

"What about the situation in space?"

Ye Han nodded and said, "I know a little."

Although he was assigned to the special service group after waking up, his rank was there, and all the documents that should be conveyed to him would not be missing, including various situations of the space fleet.

To put it simply, the current joint space fleet is mainly composed of five parts, namely the local fleet defending the earth, the Mars garrison fleet responsible for Mars, the asteroid belt task force patrolling the asteroid belt, the Jupiter garrison fleet responsible for blocking Jupiter, and the expedition fleet dedicated to field battles with the enemy.

The first four fleets are defensive in nature, and the fleet strength is average. Only the expeditionary force is the real offensive force, which concentrates the most advanced and combat-capable warships of all mankind.

The five fleets are nominally under the command of the joint command. In fact, each fleet is divided into two fleets, Beidu and International.

In order to adapt to the ever-changing situation, Beidu had carried out a large-scale strategic reorganization before Ye Han woke up, dividing the entire army into three battle clusters: land, ocean and space.

Among them, the land cluster is mainly ground and air forces; the ocean cluster includes surface combat ships and surface transport forces; the space cluster is mainly space warships and marines.

Regardless of land, surface or space, each cluster is a strategic combat unit and has the ability to launch a campaign-level attack on aliens.

It was at that time that Beidu divided the space fleet into four, with four permanent fleets on Earth, Mars, asteroids and Jupiter.

The expeditionary force is not a permanent organization. It is only temporarily formed by drawing warships when needed. In terms of pure combat effectiveness, the remaining four fleets combined are not the opponent of the expeditionary fleet.

Because fighting against aliens is a matter for all mankind, Beidu's strategic adjustment will inevitably affect the composition of the joint fleet. For this reason, Beidu conducted a series of in-depth exchanges with Washington in advance.

Washington believes that Beidu's adjustment is indeed necessary and in line with future enemy strategies, so it has also made corresponding adjustments, and finally formed the current five major fleets.

The formation of the five fleets is inextricably linked to the strategic development of mankind.

Humans suffered heavy losses in the counterattack in 2033, but the human fleet, which paid a huge price, not only defeated the fleet outside the Earth, but also successfully contained the enemies from the direction of Jupiter.

After the war, countries learned from their mistakes and set their minds on building a defense belt around Jupiter, that is, building missile bases on Jupiter's small satellites, with the intention of blocking the enemies from the direction of Jupiter in the inner circle of Jupiter.

Soon after, the asteroid belt defense plan, which came from the same source, was put on the agenda.

Neither of these two is a simple plan. To make an inappropriate analogy, building these two defense belts with the current strength of mankind is no different from the ancient national strength to build the Great Wall.

If Saturn was not too far away, the Saturn defense plan would definitely be indispensable!

Although the plan is good, it requires too many resources. The closest distance from the Earth orbit to the Mars orbit is 55 million kilometers. It is simply an impossible task to transport supplies from the Earth to the asteroid belt!

In order to reduce costs and improve efficiency, the development of Mars became the only option. Soon after the war, the United Fleet gathered a group of transport ships to deliver a large number of basic materials to Mars, and humans officially entered Mars.

In addition, larger asteroids such as Ceres and Vesta are also among the developments. All mankind concentrates its efforts, mainly based on the mineral materials on Mars and supplemented by the resources on asteroids, to build an asteroid belt military-industrial system in the shortest time.

For three years, the United Fleet relied on Martian resources to build more than 30 long-range missile bases in the asteroid belt, and the firepower network covered the entire asteroid belt.

When seeing this information, Ye Han was very surprised. More than 30 bases can cover the entire asteroid belt. Isn’t it a bit exaggerated?

But he continued to read on and soon found that it was not a miracle to do this, because the main weapons used by those bases were independently targetable ultra-long-range solid-fuel missiles carrying nuclear warheads, code-named Flash in the North and Thunder in the West.

This missile adopts a six-stage structure, the first four stages are used to rush, and the last two stages are used to pursue the target.

Its working mode is composite guidance. To put it simply, after the long-range radar network in the asteroid belt finds the target, the nearest missile is activated. Through the position prediction, the missile is ahead of the enemy ship's route.

However, in order to prevent the enemy ship from changing direction, the missile will restart after flying half of the scheduled range, determine the enemy ship's position again through the radar network, activate the second stage for the second acceleration, and adjust the flight direction during the acceleration process.

After a period of time, the missile will restart and adjust the direction. Only in the final sprint stage will the seeker on the missile lock the target and use the split guidance technology to increase the hit rate.

Interestingly, only half of the missile warheads carried by this missile carry nuclear bombs, and the other half of the warheads are smoke bombs for cover... When the enemy ship as the target finds the missile and launches an interception, the flash missile suddenly splits, releasing smoke while attacking the enemy ship. You can imagine how the aliens in the enemy ship feel!

Well, it can be said that it has taken great pains to improve the hit rate!

Due to the special combat environment, the interval between the launch and the hitting of the target of the Flash missile can be as long as more than a month. Therefore, this type of missile cannot use a more efficient liquid fuel engine, but must use a solid fuel engine that is easy to store.

If the Flash missile did not have an ultra-long range, humans would never have been able to form a defense network covering the entire asteroid belt with only more than 30 bases.

Unfortunately, the alien fleet has been accumulating strength in the past few years, and no enemy ships have entered the asteroid belt at all. The defense network built by the coalition has not yet been opened. So far, the combat effect of the Flash missile is still on paper, all of which are simulation data.

The more serious problem is that three years is really too short. The resources produced on Mars are limited. In order to build a defense network as soon as possible, the Mars fleet gives priority to building missile bases. Affected by insufficient resources, the production of Flash missiles has not been increased.

The result is that all the more than 30 bases planned have been built, but the missiles in place are only 14% of the designed number, and the defense capability is far from meeting the design standard.

With Mars' current production capacity, it only takes one to two years to complete the remaining missiles and bring the asteroid belt defense network up to design standards.

Who would have thought that the Second Fleet of the Earth's Outer Space would appear at this time!
