Of course, the purpose of the construction of this hugely expensive planetary defense system is to detect the enemy's situation at an ultra-long distance and strike at the enemy's extraterrestrial forces, but it is not for scientists on the earth to do scientific research.

Using these starry sky exploration data for scientists to conduct research and analysis, scientific exploration, further understanding of the cosmic environment, and explore the mysteries of the universe, it is just a grass to beat rabbits, a fish to eat, after all, such a big consumption, such a big investment, if you can make more use, of course, can not be wasted.

However, in the final analysis, the ultimate goal of this planetary defense system is to defend the peace of the earth, seize the strategic initiative, and avoid the recurrence of such things as alien pirate invasions.

In order to achieve such a goal, ultra-long line of sight, super strong observation and discovery system, naturally indispensable, a set of super powerful radar system, absolutely able to play a planetary defense system several times the effect, the enemy unknowingly secretly kill, against the strong enemy outside the country, how important its significance is, is simply self-evident.

However, a set of inferior radar systems, with slightly weaker observation capabilities and slightly less intelligent, may bring the enemy closer by tens of millions of kilometers or a few light-seconds distance, so that the earth has already come to the doorstep, and no trace of the enemy can be found.

In a war in the starry sky, the element of distance is extremely crucial to both the enemy and us, and if the enemy goes further, he will be in danger, and if he looks at it from a distance, he will have a little more time to prepare and a little more room to strike. One more point to win.

If the enemy cannot be spotted at the greatest possible distance. Perform quasi-targeted strikes in advance. If the enemy gives the opponent a round before he finds himself, the huge cost of the planetary defense system will undoubtedly greatly reduce the significance of its existence, and the huge investment is equivalent to a waste.

After all, compared to the alien galaxy civilization that came from afar, from the perspective of the scientific and technological level at this time, the scientific and technological power of the earth civilization. After all, there is still a limit, and it is destined to be in a state of disadvantage.

Everyone can come from afar and launch a cross-galactic civilization war, and the earthling civilization does not even have a stellar spaceship that can fly out of the earth's orbit and travel between planets, which is quite obvious from a technical point of view.

And once the technology opens up a large level, it will inevitably bring about a huge gap in the level of combat power, and the tragic situation of the former alien pirates ravaging the earth. It is undoubtedly the clearest example of the gap in combat power caused by this technological gap.

However, the technological gap is not irreparable.

Although there is no way for Earth Technology to integrate many technologies into one for the time being. The production of interstellar warships that can cruise the sea of stars, however, relying on large investment, special development, relying on the earth's native environment, relying on the planet's rich manpower, material resources, and resource advantages, even if it is by impulse accumulation, it can also pile up a powerful combat power, this kind of combat power in the space environment, there is no doubt that it is the firepower output system in the earth's planetary defense system.

After all, although the scientific and technological level of the earth civilization has not yet reached the standard of interstellar civilization, after all, there are still some achievements in aerospace science and technology, although the foundation is a little worse, but it already has the possibility of transforming the huge productive forces into space combat power, relying on local advantages, in the case of system support, this combat system still has considerable combat power, and it is fully equipped with the possibility of destroying interstellar warships.

Although the scientific and technological level of the alien civilization is high, as long as its scientific and technological level cannot be reached, it can form a comprehensive crushing height against the earth civilization in the case of long-range projection of combat power, then the earth civilization still has the possibility of victory.

After all, the alien civilization that came from afar came by driving a warship after all, and even if the warship is huge, it has its shortcomings in terms of manpower, material resources, and scientific and technological integration. The exertion of all kinds of capabilities is limited by the size and load of its spacecraft, which is a huge shortcoming compared to the advantages of the earth's own land.

The offsetting of scientific and technological advantages and local advantages has already decided that as long as the current earth civilization has sufficient awareness of space crisis and is consciously prepared for interstellar defense, then even if it encounters the invasion of alien civilizations, it will have a certain ability to resist...... And this refers to the state without the existence of the three super-standard star observation systems in the planetary defense system.

In itself, these three sets of star observation systems, according to conventional ideas, cannot be manufactured by the current earth civilization, which will also lead to the earth civilization being strongly crushed by the alien civilization at the level of scientific and technological exploration, which will lead to the local advantages of the earth civilization being partially hedged.

However, since Sima Mulong has risen on the earth now and has already created them, then, no matter how unreasonable this situation is, if an alien civilization really wants to run into it, he must admit it with his hands tied and admit that he has indeed hit a big steel plate! If he is not careful, it is not uncommon for the entire army to be annihilated.

You must know that although the level of science and technology has an impact on the improvement of the combat power of warships in various aspects, such as endurance survivability, artillery attack ability, hull resistance to strike, stealth ability, flight and movement ability, radar observation ability, etc., but on the space battlefield, the most important and direct combat effect on the front line of the battlefield is undoubtedly stealth ability, radar observation ability, and attack and movement ability.

The stealth effect of the battleship, once it reaches a certain height, the opponent's radar detection system can not detect its existence, it will make itself one-way transparent in the eyes of the enemy, and the opponent can not observe itself, and naturally it will not be able to hit, this ability is directly related to the survivability of the battleship itself, and from a certain point of view, it is much more important than the battleship's ability to resist attack.

The interstellar age, to a large extent, is a surplus of attacks, and the defense capability is relatively insufficient, and the improvement of attack power is very simple, develop more high-efficiency and high-energy offensive weapons, use material warheads with a larger charge, or use nuclear transformer missiles or other more lethal destructive weapons. In short, there are many ways to increase your attack power. It's also relatively much simpler to lift.

Although this simplicity is actually a relative concept. In fact, the vast majority of civilizations in the universe can't even do this simple loose-leaf, which is a competitive event for top students, and scumbags can only retreat.

And if you want to improve the attack resistance of the battleship's hull, it is much more troublesome in comparison.

The hull of the battleship is like an iron coffin, mainly made of various ultra-high-specification alloy materials, and if you want to improve the anti-strike ability of the battleship itself, in addition to considering the upgrading of the defensive armor and defensive shield on the outside of the hull. It is also necessary to take into account the constraints of many complex factors that make the battleship engineers want to scrap their brains, and under these many constraints, it is an extremely complex and difficult systematic project to improve the strike resistance of the warship's hull even a little.

Although the shell part of the battleship itself is cast from an extremely strong, tough, and high-temperature resistant alloy, and its resistance to external damage is extremely strong, but there are still many weaknesses in the interior of the battleship.

There are too many of these weaknesses to count, the complex and fragile life-sustaining system, the energy generation system at the core of the battleship. There are also energy lines all over the hull, and an intelligent data system for the main control of the battleship. As well as many operators in the battleship, each of these weaknesses has its own vulnerabilities, some are not resistant to high temperatures, some have poor anti-electromagnetic and high-energy ray interference capabilities, some are not resistant to strong earthquakes, and are easily damaged by vibrations, and some integrate the above defects, which can not withstand any of the damage.

While you want to safely protect the above vulnerable parts, you also need to greatly improve the impact resistance of the hull, you can imagine how high the technical content of this is, in the environment of ordinary people, if you want to do this step, the difficulty is equivalent to holding an egg in your hand and Tyson boxing, requiring a punch to beat Tyson to bleed and the egg in your hand is not broken, imagine how many people can do it?

Even if it is not a fight against Tyson at the peak, but against a fifty or sixty-year-old Tyson, I am afraid that there are not many people who are sure of this, right? Similarly, there are very few warship designers who have the ability to deal with complex problems and give solutions, and no matter which civilization they are placed in, they are absolutely scarce talents.

And even if this extremely scarce special high-end talent is successfully allocated and the design team is successfully formed, it is still a distant thing to complete the improvement of the warship's anti-strike ability, because this is by no means a simple design, test, and production problem, but a systematic project involving the entire industrial chain and industrial base.

There are many problems to be solved, the alloy material of the battleship shell obviously needs to be redesigned, and it is necessary to develop a new material with better performance and more reliable, because if there is a better one, it is obvious that it has been used before, and there is no need to re-choose new materials now, and this special material for the space battleship-level shell, its research and development, production and even processing difficulty, is obviously extremely perverted, and the time required for the entire realization process is enough to be described as long, as short as tens of hundreds of years, and as long as tens of thousands of years, which is possible。

In addition to the difficulty of hull shell materials, other difficulties of similar levels, such as the design scheme of the battleship's shield, the research and development of isolation and protection devices, materials, and new equipment inside the battleship, can easily pick out dozens of kinds, and all the difficulties can be difficult to kill.

And one of the things that is clear is that it takes much more than just time, manpower, materials, Money and so on, these things that can be calculated, maybe behind these things that can be calculated, but also the entire civilization system needs to make some unknown huge sacrifices, for a long time to work hard for a long time, this brings a final result, the cost is too high, it can be said that every little bit of the warship's anti-strike ability, it will cost countless costs and costs, relatively speaking, this cost performance is undoubtedly a little too cost-effective, in addition to those necessary warships, the choice of the maximum strength of the turtle shell thickness of the battleship, is obviously much less than the enhancement of the battleship's lethality ability。

The reason is obviously very simple, people develop five-cent artillery battles, and fight on top of the suit you bought for 50,000 yuan, under the same situation, even if it is a rich local tyrant, it is obvious that they will not choose the turtle shell strategy as the main direction of attack, because the cost performance is too low, and the low is completely unbearable, and those who have brains will not take this road.

In the state of excess attack power in the interstellar era, sometimes even if the technological level is stretched a huge distance, but the low-level technological civilization, as long as it can attack the warship of the high-level civilization, can also bring huge damage, even the high-level civilization warship cannot withstand the saturated artillery attack of the low-level civilization warship.

So in this case, since you can't afford to withstand the firepower, then just hide from it, I will vigorously develop stealth warships, so that your radar observation system will not be able to observe the existence of my warships at all, in that case, even if your lethality is strong, you can destroy a planet with a single star destroyer, it is obviously useless, no matter how lethal it is, if you can't find it, you can't hit it, it's not like it's not a good egg.

It is precisely because of this consideration that many civilizations have developed the stealth ability of warships and the-for-tat competition of radar detection capabilities.

After all, although the development project of the stealth capability of the battleship is quite difficult, in addition to the research and development of the stealth coating of the warship's shell to evade the radar detection of multiple modes, it also involves the design of the overall hull shape, and even the concealment design of various shipborne equipment inside the hull, but no matter how difficult this project is, it is far inferior to the difficulty of the project of improving the anti-strike ability of the warship body.

And once the stealth ability of the battleship has been rapidly improved, so that one side has obtained a completely one-way transparent ability in the battlefield, it is obvious that the battlefield situation will produce subversive changes, and the two sides with equal strength will have completely unequal combat power changes because of the unequal stealth capabilities, which is enough for the stealth side to form a suppressive crushing attack on the other side, so that the other party does not want to fight it, and the country will be destroyed in World War I.

It is precisely for this reason that the importance of radar observation capabilities is clearly highlighted.

The observation ability determines the battleship's perception of the battlefield situation, and the ability to search and discover enemy targets, which can not only help the battleship avoid the real and attack the weak, hit the enemy's important targets, but also help the battleship avoid the enemy's firepower.
