For the second line of defense, a large number of warships were activated in each defense zone, and they sailed out of the defense line and flew in the direction of the first line of defense.
This was originally one of Belt's backup plans for this war.
Nowadays, it has been used early.
"Admiral West, all gravity cannon battleships have arrived at their designated locations!"
Tens of seconds later, the adjutant turned his head and reported to Wester!
"Okay, order them to open fire immediately to assist the defenders on the first line of defense and push back the Zerg offensive!"
"clear!"
There are 5 billion gravity gun warships scattered in 58 defense zones, with an average of more than 80 million warships deployed in each defense zone.
The moment they received the order, they all roared!
As mentioned before, unlike ordinary weapons, gravity cannons are actually further utilization of space technology. Therefore, they do not require a shooting path. Once fired, they will act directly on the attack point.
In other words, the gravity cannon can carry out an attack like hitting a cow from across the mountain. All you need to do is hide behind the defense line and keep firing. Most of the Zerg attacks will be blocked by the fleet on the defense line, which poses no threat to the gravity cannon fleet.
Very small.
After the firing, there was almost no time interval. At the front of the Zerg fleet, gravity tides appeared in countless small areas in an instant. Then, due to the uneven distribution of gravity, tearing phenomena occurred. Finally, after a few seconds,
, all the Zerg warships in the area were destroyed!
Although the gravity cannon is only the original version of space tearing, its attack range is not small!
The killing range of each gravity cannon is about 30 kilometers!
In terms of the array density of the Zerg fleet, such a range is enough to cover about ten warships!
Finally, coupled with the gravity cannon attack, it acts directly on the target position with no time interval in between. In other words, it is destroyed immediately after aiming, and you have no chance to evade it!
Therefore, just one wave of attacks by the 5 billion gravity battleships caused huge casualties to the Zerg fleet, destroying tens of billions!
After all, the front of the Zerg fleet is already in contact with the defenders on the first line of defense. Therefore, the overall array is not advancing at high speed, and the warships are crowded together at a high density.
That's why this wave of attacks achieved such great results.
If we had deliberately kept a distance from the opponent and spread out the fleet array like in the Gilt Siege and Annihilation War, the casualties would have been countless times smaller!
However, this is not the Zerg style!
The entire Zerg fleet's offensive paused for an instant, while the defenders on the first line of defense took the opportunity to reorganize their firepower network and withstand the Zerg fleet that was about to confront them.
"Gravity cannon?"
Herme, who was watching the battlefield through the Zerg spiritual network, was also a little surprised!
He originally thought that the fifth-level civilization in this galaxy was only in the middle stage at best, but the scene before him changed his mind!
Gravity cannons are definitely not something that a mid-level fifth-level civilization can create. It involves some advanced applications of space technology. Usually only late-level fifth-level civilizations, or even fifth-level civilizations at their peak, can master it!
Yes, it’s just possible to master it. Most civilizations that master this technology are early level 6 civilizations!
Although the gravity cannon in front of me, in terms of attack range and attack speed, seems to be slightly worse than the gravity cannon that is the main weapon of the early level six civilized battleships that I know, it cannot be denied that this is indeed a gravity cannon.
Just a little more original.
Fortunately, the number is not large, only a few billions. If there were trillions, Herme should consider retreating, or even escaping from the galaxy!
In fact, what Herme didn't know was that the gravity cannon accidentally developed by Virto's scientific research team was not only much worse in power and attack distance than the early level 6 civilization, but its attack range was even ridiculously close!
You must know that the attack range of the main weapon used by a level 6 civilization, even in its early stages, is the gravity cannon, is at least 20-30 million kilometers.
In comparison, the gravity cannon of the Vera Federation is more than one generation behind!
Although the gravity cannon fleet has demonstrated its powerful attack power, it seems that it can only suppress the progress of the Zerg, which is already the limit. It seems impossible to repel the Zerg fleet.
.
The most important thing is that although the gravity cannon is powerful, it consumes a huge amount of energy each time it fires. When the energy reserve is sufficient in the early stage, it can attack as fast as once a minute.
However, after a period of time, the reserve energy is exhausted and can only be recharged by relying on the core energy. Due to the output speed of the core energy, after ensuring the normal operation of the battleship and maintaining the space shield, its firing speed will be instantly reduced to
About once every three minutes.
Sure enough, five minutes later, the attack frequency of the gravity cannon fleet suddenly dropped sharply, finally forcing the Zerg fleet to a situation 1 million kilometers away. Now, due to insufficient follow-up firepower, the Zerg fleet was pressed up again!
"Damn it, even with the use of the gravity gun fleet, they still couldn't suppress the Zerg to a safe distance!"
Looking at the pictures and various information displayed in the tactical video, West said loudly unwillingly.
"Do you want to withdraw the gravity gun fleet, Admiral?"
"No, let them continue to attack and cooperate with the defenders on the first line of defense to delay the Zerg's approach as much as possible!"
"But..."
"No but, execute immediately!"
"Yes, General West!"
In fact, for the adjutant, West's order was very confusing.
Now that the gravity gun fleet has lost its greatest role, the best strategy is to withdraw it to the second line of defense, recharge the reserve energy, and then cooperate with the second line of defense to defend.
However, judging from General West's intentions, he had no intention of letting them withdraw. Instead, he seemed to be preparing to let them coexist and die with the first line of defense!
This made him very puzzled!
"Even if the attack power drops suddenly, with the cooperation of the gravity cannon and the defenders on the first line of defense, it is still no problem to continue to withstand the Zerg for 10-15 minutes, and this time is enough for us!"
"Because...the strongest reinforcements will arrive soon!"
Looking at the adjutant who was giving orders with doubts on his face, West seemed to be talking to himself.
The strongest reinforcements?
What on earth is the general talking about?
Even the fleets of the three giants have fled, where are the reinforcements, and they are still the strongest?
Wait, could it be?
"General West, a large number of fleets are arriving in all the war zones!"
"This is...this is the battleship of the Human Federation!"
Just as the adjutant was guessing, the voice of calling for an enemy officer came to his ears!
