"What are you peeking at? Put the home screen! " Yip hon said discontentedly

Qi Haifeng shrugged his shoulders and pointed his finger at the screen and immediately added a lot of words to say
I don’t know if you look at it. The so-called super cannon root is not the kind of large laser cannon that everyone wants, but the laser cannon array spelled out by ordinary laser cannons!
Three flat craters were selected on the surface of the moon in Beiyuezhou. First, a large number of cables were laid at the bottom of each crater, and then a large number of laser transmitters were placed. Each laser covers an area of 2 square meters and needs to be maintained exactly one square meter.
The first array was built, with a diameter of one kilometer. There are 7539 small lasers in the array, and there are more than 20 nuclear reactors with array energy alone 2.
Although the effective range of each laser is in the early five kilometers, the effective range of nearly 100 thousand lasers can reach more than 70 thousand kilometers after being combined together!
The diameter of the second array is 1200 meters, although it is 200 meters more, but the number of lasers is more than 1.13 million. The effective range is over 90 thousand kilometers and the longest range is 120 thousand kilometers.
The largest array No.3 has a diameter of 1,500 meters, and it is planned to install more than 1.76 million lasers, almost the sum of No.1 and No.2, with an estimated range of 100,000 kilometers.
However, array No.3 needs too many lasers, and even if Beiyuezhou tries hard, it can’t produce so many lasers. Up to now, array No.3 has just completed a small part, and about 450,000 lasers have been put in place.
Because the aliens approached the third array, the construction had to be temporarily stopped and the existing array was debugged before the aliens arrived. Although it was far from the planned range, there was still an effective range of 40 thousand kilometers
Just now, the fire was the third array. If the third array is completely completed, there is no need to consume the fleet on the moon. It is necessary to lure the alien fleet to the vicinity of the moon, and the alien fleet can be cleaned up by the laser cannon array alone.
Unfortunately, the completion of the third array is far away, and the first and second artillery arrays are not in this direction.
Chapter 111 Level 3 defense body
After reading the information, everyone stared at each other for a long time, and there was a feeling that the dog felt hundreds of thousands of lasers at every turn. Is this still the moon?
Although the cost of building a laser array is not as high as that of a capital ship, the power of the laser array exceeds that of all active capital ships. It can be said that human beings have the strongest weapon at present, and even nuclear weapons have to be pulled over.
Moreover, in order to facilitate the maintenance of the North Moon Island, all lasers are of the simplest structure, and even the surface control equipment is much more precise than the laser … In other words, the control equipment is the most critical foundation of the laser gun array.
Think about it. If the control equipment is not precise enough, how can more than 700,000 lasers aim at targets tens of thousands of kilometers away at the same time? How can so many lasers fire at the same time and finally hit a target point together?
Coordination alone can be a headache.
Another disadvantage of this thing is that it must be fixed on the ground. If it can be loaded with warships … Well, it doesn’t have to be loaded with warships. It can also achieve the same effect by getting more warships to volley.
But in this situation, it’s hard to say when Beiyuezhou can save so many warships.
Yip hon noticed that the first array attacked the fleet when it was built, and soon after it set off, the military prepared for the aliens to hit the earth.
He suddenly woke up. "Do you think there is such a super cannon on the earth?"
"There should be?" Xiaoyuan said carefully
Don’t look at him, but here are the places with the lowest rank. Today, he is particularly low-key
Unexpectedly, yip hon suddenly shook his head at this question. "I wish I had it, but the possibility is too small."
"What?" Xiao Yuan is puzzled.
"Because of the truth," said Yip Han, "there is really no wind, rain and fog on the surface of the moon, but the laser can always stand there; The earth is different. If the laser is left for a long time, it will definitely go wrong. Even if it is, it can’t be placed directly like the moon. I think it is more likely that the scattered artillery positions will be fired. At the same time, there are enough artillery positions, and the power is definitely not worse than the arrays of the moon. "
"That would be great!" Everyone’s heart suddenly gives birth to a kind of hope, hoping that the laser net can stop aliens.
Yip hon said, "Can we wait and see? Let’s go back to Laoqi and let us know if there is anything we can do to help."
"Don’t worry," Qi Haifeng promised.
Say what to do, but the alien fleet over there is flying to the earth. Who doesn’t feel like carrying a big stone in his heart?
If a ship is conscious, it is necessary to worry about the fate of the earth.
The people spent a long day in deep depression, and the next day they couldn’t help but rush to the bridge.
Yip hon was a little earlier than scheduled, but when the bridge door hit, he was startled to find that others were already waiting in the bridge.
He slowly drifted into the bridge and waved at everyone. "How’s Lao Qi?"
"Just after synchronous orbit, it is decelerating," said Qi Haifeng.
Yip hon casually found a position "how does the earth react?"
"Nothing special. The rail gun array should be ready," Qi Haifeng said. "The aliens are quite sophisticated and play with the short radius."
"An adventurous? Test "yip hon twist a head to look at the screen.
More than 200 enemy ships have been divided into several groups, which are farthest from the earth and near the synchronous orbit, and have recently approached the laser satellite.
Laser satellites have been waiting for a series of satellites to spread their wings, and the angles and directions of photovoltaic panels are surprisingly consistent and neat, which looks full of momentum.
"Sure," Qi Haifeng said.
Yip hon suddenly found that there were alien ships in all directions of the earth, but there was no enemy ship in the direction of the moon. He pointed to the screen and said, "Is this what scared the super cannon?"
The distance between the earth and the moon is 300 thousand kilometers, and the planned range of the No.3 laser cannon array is 100 thousand kilometers. There is no need for aliens to hide so far
Qi Haifeng laughed. "I was scared, but I didn’t follow the moon."
Yip hon glared at "sell less and hurry"
Qi Haifeng even promised to point to the screen and say, "Beiyuezhou has not only developed a super cannon, but also a three-level defense body."
"What the hell?" Ye Han straightened his ears.
"Three-level defense" Qi Haifeng repeated, "To put it simply, the earth and the moon built three super cannons, and the lunar cannon protected the first level and then the second level. The alien who covered the earth wanted to go this way, got a gun and returned."
Yip hon mind immediately appeared from the third-level firepower can’t help some stupidly "why don’t you install warships with this technology?"
"You got me there," Qi Haifeng said. "That’s all I got."
Longjian National Road "may have some defects."
Yip hon tiny one zheng thoughtfully nodded.
At this time, the alien warships finally flew to the ship door near the satellite cannon array, and the ice-white alien fighters floated out like wearing Hua Hudie and then rushed to the satellite cannon in droves.
As soon as the fleet entered the range, the satellite light cannon automatically fired a series of lasers flying out of the gun tube and destroyed the enemy planes one by one neatly.
Not to be outdone, the alien fleet fired insect bombs at the satellite.
The straight-line distance between the two sides is less than 100 kilometers, and it won’t be long before the insect bomb flies over this point. It’s not as good as the man-machine simply doesn’t know how to avoid it. It’s even more when it’s smashed on the spot by the insect bomb or destroyed by the acid bomb.
