Armor Frenzy

The construction speed of the asteroid belt defense network is lagging behind, and it is also directly related to the construction of the Jupiter defense network.

You must know that the asteroid belt at that time did not directly face the alien fleet, and the planned Jupiter defense belt had not yet laid the foundation, and ushered in the first impact of aliens.

Although the expeditionary battle severely hit the aliens on Jupiter, they were either hidden in the depths of tens of kilometers underground or under water tens of kilometers deep.

Shortly after the battle, signs of alien activity appeared on Ganymede's surface. In order to prevent the enemy from resurgent, the joint command decided to give priority to building a Jupiter defense network, regardless of personnel or materials, all tilted toward the Jupiter defense network.

Under this arrangement, missile bases in the direction of Jupiter were built and used one after another, and the initial defense network was soon formed to block Jupiter with long-range missiles.

In order to achieve the purpose of saving resources, the first batch of missile bases in the direction of Jupiter are basically built on the satellites outside Callisto, mainly the satellite groups of Io and Himalia, and the semi-major axis is 12 million kilometers. Inside, there are a total of five satellites and twelve missile bases.

The missiles used to block Jupiter have some technical ties to the flash, but are less complex in structure and have a much shorter range than the flash.

He noticed that the information said that the technical difficulty of those missile bases is not the missiles, but the bases themselves!

Ye Han deliberately checked and found that the missile base is not complicated, it is nothing more than an integrated fully automatic weapon system including detection, locking, launching and other functions. For the current technical level of mankind, it is completely complete from design to completion. No stress, the real trouble is how to power these bases!

It is impossible for human beings to build power stations on those barren satellites, where there are no conditions for power generation, and the only power supply equipment that the base can use is batteries.

Automatic missile bases are big consumers of electricity. No matter how advanced high-energy batteries are, they can't last for too long. The only way is to use photovoltaic cells.

Ye Han knows that the light level of Jupiter is only 4% of that of the earth. In order to get enough electricity, the number of photovoltaic cells must be increased, and the photovoltaic cells must be placed on the surface of the satellite that can receive sunlight. In this way, the photovoltaic cells become It has become the short board and weakness of the missile base.

The threat comes from two aspects. First, the large-scale laying of photovoltaic cells will inevitably attract the attention of aliens, while the target of long-range missiles is alien warships. Only a large enough aircraft can attract the attention of the automatic system. If aliens use When a small spaceship lands, the system may not activate the missile.

In order to protect the photovoltaic cells, the coalition had to add an additional batch of medium- and short-range missiles to prevent aliens from landing on the satellite.

Another power comes from the powerful radiation belt of Jupiter itself, which is the natural enemy of all electronic equipment. Any electronic equipment in the missile base must be sealed in a radiation-proof casing.

The impact of strong radiation on radar is even more serious. Ordinary radar cannot operate normally near Jupiter at all. High-power radar can be used, but the effect is not very good. Finally, composite methods have to be used to capture the target with optical lenses and lock with lidar. goal to solve this thorny problem.

It may be that human actions have attracted the attention of aliens. Shortly after the first phase of the Jupiter defense network was delivered, an alien fleet consisting of three warships tried to leave, but the fleet was still in the acceleration stage and was attacked. In the long-range interception of the defense network, none of the three alien warships escaped the net, and were successively destroyed by long-range missiles.

The actual combat effect of the defense network has been initially proved, but it takes three to five missiles to destroy an enemy ship. Calculated by 16 missiles per base, the entire defense network has only 192 missiles. As long as you are willing to pay, once With 180 warships dispatched, aliens can break through the defense network at any time!

Originally, the Jupiter defense network was unmanned, but after many problems were put on the agenda, the coalition had to abandon the unmanned plan and set out to form the Jupiter fleet.

Fighting against the alien fleet in the direction of Jupiter is only the second task of the Jupiter fleet. Its first task is actually to maintain the normal operation of the Jupiter defense network.

The coalition also plans to build a multi-functional integrated fleet base for the Jupiter fleet on the 170-kilometer diameter Ganymede that integrates supply, maintenance and manufacturing.

The Jupiter Fleet has made all the preparations to build the base, but due to the tight supply of raw materials, this base is still on paper... The Jupiter Fleet has chosen a location for a few years, and now it is the anchorage of the fleet, and all the warships without missions are stop there.

There is unconfirmed news to the effect that the Jupiter Fleet has the idea of ​​being self-reliant and intends to dig underground space to lay a foundation for the construction of a base in the future. I don’t know if this is really the case.

Later, the aliens in the direction of Jupiter made several attempts, but there were few human bases and few alien warships. With the assistance of the Jupiter fleet, several conflicts ended in human victory, and humans successfully blocked Jupiter. .

Later, there were more and more enemy warships, and Jupiter's defense network became more and more perfect. The missile base began to expand to the Yananke satellite group... The semi-major axis of this satellite group is about 20 million kilometers, which is similar to Jupiter's. The distance is a bit far, and I have to use a missile with a longer range, and I simply replace it with a flash missile in the later stage.

Afterwards~www.readwn.com~ The coalition believes that there is no need to continue to expand the defense network outward, and focus on strengthening the strength of the inner defense network. The number of missile bases has grown from twelve to twenty-seven, and the Jupiter defense has gradually formed today. system.

The last trial on Jupiter took place in December 1934. The failed ending finally made the aliens in the direction of Jupiter realize the reality. They had to choose dormancy. After more than two years, not only did they no longer send warships, they Even servants and giant insects rarely appear on the surface of the moon.

But all the coalition forces believed that the enemy could not give up. They were just accumulating strength. The aliens had abnormal ship-building capabilities. Building hundreds of warships in two years was like playing.

Therefore, the coalition has never dared to relax, and has been strengthening Jupiter's defense capabilities, not only increasing the number of missiles, but also gradually strengthening the strength of the Jupiter fleet.

Today's Jupiter defense network is not what it used to be. Its core blockade radius is 12 million kilometers, and the farthest blockade distance is 20 million kilometers. If you want to break through the blockade of the defense circle, you have to pay at least three hundred to four The heavy price of a hundred warships.

This is only the price of breaking through the defense network. If the strength of the Jupiter fleet is also included, the enemy will have to pay the price of one to two hundred warships.
