The construction speed of the asteroid belt defense network lags behind, which is also directly related to the construction of the Jupiter defense network.
You must know that at that time, the asteroid belt did not directly face the alien fleet, and the planned Jupiter defense belt had not even laid the foundation before it ushered in the first impact of aliens.
Although the expeditionary campaign severely dealt a blow to the aliens on Jupiter, they were either hiding tens of kilometers underground or underwater dozens of kilometers deep. The expedition fleet was unable to completely eliminate the enemies of Jupiter.
Shortly after the battle, signs of alien activities appeared on the surface of Ganymede. In order to prevent the enemy from resurrecting, the joint command decided to prioritize the construction of the Jupiter defense network, regardless of personnel or materials, all tilted towards the Jupiter defense network.
Under this arrangement, missile bases in the direction of Jupiter were built and put into use one after another, and an 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 were basically built on the satellites outside Callisto, mainly the Callisto and Himalia satellite groups, with the semi-major axes of 12 million kilometers.
Within it, there are a total of five satellites and twelve missile bases.
The missiles used to block Jupiter are technically related to the Flash, but their structure is not as complex as the Flash, and their range is much shorter than the Flash.
He noticed that the information said that the technical difficulty of those missile bases was not the missiles, but the bases themselves!
Ye Han checked it specifically 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. With the current level of human technology, it is completely complete from design to completion.
No pressure, the real trouble is how to provide power to these bases!
It is simply impossible for humans to build power stations on those barren satellites. There are no conditions for generating electricity at all. The only power supply equipment that the base can use is batteries.
Automatic missile bases are large consumers of electricity. No matter how advanced high-energy batteries are, they cannot last for a long time. The only way is to use photovoltaic cells.
Ye Han knew that the illumination level of Jupiter was only 4% of that of the Earth. If you want to get enough electricity, you must increase the number of photovoltaic cells, 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 shortcomings and weaknesses of the missile base.
The threat comes from two aspects. First, laying photovoltaic cells over a large area will inevitably attract the attention of aliens, and the target of long-range missiles is alien warships. Only aircraft that are large enough can attract the attention of automatic systems. If aliens use
When a small spacecraft lands, the system may not activate the missiles.
In order to protect the photovoltaic cells, the coalition had to add an additional batch of medium-range 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 enclosure.
The impact of strong radiation on radar is even more serious. Ordinary radar cannot operate normally near Jupiter. High-power radar can be used, but the effect is really not very good. In the end, composite methods have to be used, using optical lenses to capture targets and laser radar to lock on them.
goal to solve this thorny problem.
It may be that human actions attracted the attention of aliens. Shortly after the first phase of the Jupiter Defense Network project was delivered, an alien fleet composed of three battleships tried to leave. However, this fleet was still in the acceleration stage and was attacked.
During the long-range interception of the defense network, none of the three alien warships escaped the network and were successively destroyed by long-range missiles.
The actual combat effectiveness of the defense network has been initially proven, but it takes three to five missiles to destroy an enemy ship. Calculated based on sixteen missiles per base, the entire defense network only has 192 missiles. As long as you are willing to pay, one can
With one hundred and eighty warships dispatched, aliens can break through the defense network at any time!
Originally, the Jupiter defense network was designed by an unmanned system, but after many problems were put on the agenda, the coalition had to abandon the unmanned plan and start building a Jupiter fleet.
Fighting against the alien fleet in the direction of Jupiter is only the second mission of the Jupiter fleet. Its first mission is actually to maintain the normal operation of the Jupiter defense network.
The coalition also plans to build a multi-functional comprehensive fleet base for the Jupiter fleet that integrates supply, maintenance and manufacturing on the 170-kilometer-diameter moon Callisto.
The Jupiter Fleet has made all preparations to build a base, but due to the tight supply of raw materials, this base is still on paper... The Jupiter Fleet has chosen the location for several years, and now it is the anchorage of the fleet, and all the warships have no missions.
Stop there.
There is unconfirmed news, to the general effect that the Jupiter fleet has the idea of reliance and plans to dig underground space to lay a foundation for future base construction. I don't know if this is true.
Later, aliens in the direction of Jupiter conducted several more trials, 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, Jupiter's defense network became more and more complete, and the missile base began to expand to the Anank satellite group... The semi-major axis of this satellite group is about 20 million kilometers, which is about the same as that of Jupiter.
The distance was a bit far, so we had to use missiles with a longer range. Later, we simply replaced them with flash missiles.
Later, the coalition felt that there was no need to continue to expand the defense network outwards, and focused on enhancing the strength of the inner defense network. The number of missile bases increased from twelve to twenty-seven, gradually forming today's Jupiter defense system.
The last test by Jupiter took place in December 34. The failure finally made the aliens in the direction of Jupiter realize the reality. They had to choose to lie dormant. For more than two years, not only did they no longer send out warships, they
Even minions and giant insects rarely appear on the surface of the satellite.
But everyone in the coalition believed that the enemy would never give up. They were just accumulating strength. Using the abnormal shipbuilding abilities of aliens, building hundreds of warships in two years was just like playing games.
Therefore, the coalition forces never dare to relax and have been strengthening Jupiter's defense power. Not only are they increasing the number of missiles, but the strength of the Jupiter fleet is also gradually strengthening.
Today's Jupiter defense network is no longer what it used to be. Its core blockade radius is 12 million kilometers, and the furthest blockade distance is 20 million kilometers. If you want to break through the blockade of the defense circle, you have to pay at least 300 to 400 yuan.
The heavy price of hundreds of battleships.
This is only the cost of breaking through the defense network. If the strength of the Jupiter fleet is also taken into account, the enemy will have to pay the price of another one to two hundred battleships.
