On 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 towards the first line of defense.
This was originally one of Belt's backup plans for this war.
Now, it has been used early.
"General West, all Gravity Cannon battleships have arrived at their designated locations!"
Tens of seconds later, the adjutant turned to report 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!"
"Understood!"
There are 5 billion Gravity Cannon warships scattered in 58 defense zones, with an average of more than 80 million warships deployed in each defense zone.
The moment they got the order, they all roared!
As mentioned before, unlike ordinary weapons, Gravity Cannon is actually a further utilization of space technology. Therefore, it does not require a shooting path. Once fired, it will act directly on the attack point.
In other words, Gravity Cannon can carry out an attack like beating a cow across a mountain. It only needs to hide behind the defense line and keep firing. Most of the Zerg attacks will be blocked by the fleet on the defense line, posing very little threat to the Gravity Cannon fleet.
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 the uneven distribution of gravity caused a tearing phenomenon. Finally, after a few seconds, all the Zerg Warships in the area were destroyed!
Although Gravity Cannon is only the original version of Spatial Tear, its attack range is not small!
The killing range of each Gravity Cannon shot 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, after adding the Gravity Cannon attack, it acts directly on the target position, and there is no time interval in between. In other words, the target is destroyed immediately, 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?"
Helme, who was looking at the battlefield through Zerg Mental Network, was also a little surprised!
He originally thought that the highest Level 5 Civilization in this galaxy was only in the mid-term, but the scene in front of him changed his mind!
Gravity Cannon is definitely not something that can be manufactured by just one Mid-Level 5 Civilization. It involves some advanced applications of space technology, and usually only Level 5 Civilization in its later stages, or even Level 5 Civilization at its 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 seems to be slightly worse in terms of attack range and attack speed than the Gravity Cannon, which is the main weapon of the early level six civilized warships that I know, it cannot be denied that this is indeed Gravity Cannon, just slightly more primitive.
Fortunately, the number is not large, only a few billions. If there were a trillion-level number, Helme should consider retreating, or even escape Milky Way!
In fact, what Helme doesn't know is that Gravity Cannon, which was accidentally developed by Verto's scientific research team, is not only much worse in power and attack distance than the early level 6 civilization, but its attack distance is even ridiculously close!
You must know that the attack range of a level 6 civilization, even in its early stages, as the main weapon used by the gravity cannon, is at least 20-30 million kilometers.
In comparison, Vera Federation's Gravity Cannon 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 the limit. It seems impossible to repel the Zerg fleet.
The most important thing is that although 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. Limited by the output speed of the core energy, after ensuring the normal operation of the battleship and maintaining Spatial Shield, its firing rate will instantly decrease 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 Cannon 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.
"Are you going to withdraw the Gravity Cannon fleet, General?"
"No, let them continue to attack, cooperate with the defenders on the first line of defense, and try to delay the time for the Zerg to come up!"
"But."
"No but, execute immediately!"
"Yes, General West!"
In fact, for the adjutant, West's order was very confusing.
Now that the Gravity Cannon fleet has lost its greatest role, the best strategy is to have it withdraw 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 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 Big Three's fleet has 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 Human Federation's battleship!"
Just as the adjutant was guessing, the voice of calling for the enemy officer came to his ears!
