Two days after the air attack on Callisto, the assault fleet finally arrived near Ganymede.
From the perspective of all fleet members, although the trajectory of the fleet from Callisto to Ganymede is not a straight line, it is also a nearly straight line that is not very curved. However, since the fleet is also orbiting Jupiter while changing orbit, if the perspective is
If you place it beyond Jupiter, you will see a very obvious arc.
Ganymede, like Callisto, has long been locked by Jupiter's strong gravity, always facing Jupiter. Gao Kai continued to use the tactics of air strikes on Callisto. The fleet stopped outside Ganymede and opened a safe distance far enough away.
distance.
The aliens are more attentive to the management of Ganymede. There are more than ten times the number of densely packed ground buildings than on Callisto, and there are even more air defense positions one after another. This is only what can be seen on the surface, and cannot be seen hidden underground.
I don’t know how many there are.
Faced with such a huge defense system, even if Gao Kai is confident, he has to pay attention to it. The most direct manifestation is to park the fleet more than 1,500 kilometers away from Ganymede!
This distance is more than twice the effective range of Thin Light, but from top to bottom in the entire fleet, no one thinks Gao Kai's decision is wrong.
At 14:00 in the afternoon, the air strike officially started. An air carrier, four destroyers, eight frigates and three assault ships participated in the air strike.
Since only the electromagnetic gun was used, the artillery fire in the air strike seemed a bit sparse, and the hit rate was not very good. It was considered good to destroy a target with three shells. However, during the air attack on Callisto, on average, only one of the seven shells missed.
There is no way, the distance is too far, even beyond the effective range of the electromagnetic gun. Even if the electromagnetic gun shells fly over this distance, it will take more than four minutes, and the distance brings not only a time problem, but also the spread of the impact points.
expands as the distance increases, resulting in a lower hit rate.
The assault fleet was having a good time, and the aliens on Ganymede were not idle. The first batch of cannonballs had just approached Ganymede, and countless thin lights shot up into the sky without warning. The originally calm star
The surface boiled instantly, and it was impossible to count how many tiny lights shot up into the sky at the same time.
"Holy shit!" Gao Kai subconsciously said two words. If it weren't for the seat belt, he would have floated up from his seat. "How many bugs are there?"
Lu Zuo quickly called up the statistics: "The total number is between 24,000 and 27,000, with an error of not more than 1,000."
It would be good to have a supercomputer. If the previous central computer was modified, it would take at least half an hour to complete such statistics.
"So many?" Gao Kai gritted his teeth and turned to Ye Han, "Ye Han, should we use nuclear weapons now?"
The power of the electromagnetic gun is good, but it is only good. The destructive power is equivalent to that of a heavy artillery. If you want to achieve the effect of a nuclear weapon, the shell must weigh at least several tons, not just 50 kilograms.
Ye Han thought for a while and said: "Good steel must be used on the blade."
The mission of the assault fleet is to hurt the aliens so much that they have to move the fleet back. Slowly grinding the electromagnetic cannon can indeed slowly kill the ground firepower on Ganymede, but it takes too long.
The attacking fleet cannot wait, the intercepting fleet cannot wait, and the earth cannot wait either.
Gao Kai received Ye Han's support and immediately nodded: "Change the shells!"
With the anti-aircraft firepower of Ganymede, the possibility of missiles escaping interception is infinitely close to zero. Only artillery shells have the chance to penetrate the fire network.
Note, it’s just an opportunity, not a grasp!
Although the fleet was unable to monitor the flight of the cannonballs due to the wrong position, the thin light was too dense. The massive beams of light did not care where the cannonballs went, they just focused on stopping them in front of the cannonballs. No matter how fast the cannonballs were, they would inevitably hit the beams.
superior.
Regarding this, no one can provide direct evidence, unless a warship uses a super-high-speed camera to film the whole process from the side.
However, the effect of the first wave of tungsten alloy shells when they landed was much worse than the previous few days. Gao Kai could not find a more reasonable explanation except that the shells were divided by fine light.
There is also the ridiculous hit rate. Although the distance is a bit far, it has not exceeded the maximum range of the electromagnetic gun. There are so many missed shells, is there no reason?
Can artillery shells be intercepted?
The answer is yes, the fully automatic close-in defense cannon on the battleship can do it, but only the laser close-in defense cannon has this capability, and it can only intercept lower-velocity shells.
The detection radar equipped with close-in defense guns has the ability to detect high-speed flying shells, but the response speed of the interception system is limited and the power of the laser is also limited. Even if the laser accurately shines on the shells, it will not be able to destroy the shells because the illumination time is too short, unless
The laser shines on the same location for a long enough time.
However, even if the laser is always pointed at the same position, it won't work, because the speed of the cannonball is so fast that before the irradiation time reaches the target, the cannonball will have already fallen on the battleship.
In short, intercepting artillery shells is not as easy as imagined.
Of course, these are all human technological achievements. No one knows whether aliens have more powerful technology.
Judging from Gao Kai's experience, there shouldn't be. Could it be that the reaction speed of insects is faster than that of electronic equipment? That is absolutely impossible.
In order to increase the hit rate, Gao Kai did not order the firing immediately, but first commanded the fleet to disperse so that the fired shells would no longer be concentrated, and then sent out the nuclear shells sandwiched among many electromagnetic shells.
It only takes four minutes for an electromagnetic artillery shell to land, while it takes eight and a half minutes for a nuclear artillery shell. Moreover, the effective range of ordinary naval guns is too short, and there is no way to guarantee the hit rate. It is definitely no problem to hit Ganymede, but can it hit it?
Goals are purely based on luck.
Fortunately, nuclear weapons do not require high precision. As long as they are hit near the target, they will have the desired effect... It is not a big problem if they miss the target. Who made the surface of Ganymede full of alien buildings and positions?
?
The shells hit Ganymede one after another like no money. The aliens' positions suffered a lot of damage, but the interception fire showed no sign of stopping. Everything seemed so step-by-step.
At this moment, a bright light suddenly burst out from the surface of Ganymede. After the brief bright light dissipated, a huge fireball suddenly spread. The center part rose rapidly, and the edges quickly spread outward, forming a ball buckled on the ground.
A huge hemisphere, and a hemisphere that is constantly expanding.
The fireball only lasted a few moments longer than the strong light, and soon disappeared. However, everything covered by the fireball was destroyed, and the nearby alien positions were not spared. The aliens and giant insects there were strongly affected.
