The muzzle velocity of ordinary artillery shells generally does not exceed two kilometers per second, and the naval guns of the expeditionary fleet have not undergone any special strengthening, but in the vacuum environment of the universe, the muzzle velocity has a certain bonus, which is about 2,400 meters per second.

And the expeditionary fleet did not shoot ordinary shells, but rocket-accelerated bombs.

This thing is actually an ordinary rocket range extender projectile, but there is no resistance in space, and the shell can fly down without restrictions as long as it does not hit the target, and there is no range limit, and the role of the rocket can only be to increase the speed, so it was renamed the speed increase bomb.

The speed of the cannonball itself, combined with the rocket bonus, has exceeded three kilometers per second after six seconds, and the crimson cannonball tears through the dark space, turning into dozens of rainbow lights and rushing towards Ganymede.

Compared with the speed of the battleship at every turn, the speed of the artillery shell is really nothing, to put it mildly, even if the expeditionary fleet uses the barrel to push the butt of the alien battleship, the shells fired out will not be able to catch up with the target.

But dead data on paper is of little use in battle, the really important data is the relative velocity between the expeditionary fleet and the target!

The position of the Second Fleet is seven or eight hundred kilometers from Ganymede, and it always maintains this distance, and retreats as soon as it detects signs of an approaching alien fleet.

This is because the effective range of fine light is about 600 to 700 kilometers!

The range of fine light is not obtained casually, but is calculated through the combat data of the First Fleet and the combat experience of the Second Fleet during this period, and I dare not say that it is absolutely accurate and not too much worse.

Directed energy weapons are not good at this, the power of a little farther away will drop sharply, the same is true of human lasers, and the same is true of the fine light of aliens, but missiles and shells are not so limited.

Gao Kai's bullying is the lack of fine light range.

If the target is an alien warship, the battleship will not know where to fly when the shell flies to the place, but Ganymede is a satellite, a satellite with a fixed speed and an orbital orbit, and there is no way to avoid it, and it is simply a good target.

At this moment, the core of the battlefield is neither the expeditionary fleet nor the alien fleet, but the alien fleet entrenched on Ganymede, the relative speed of the enemy and us is very low, the second speed of more than 3,000 meters has exceeded the reaction speed of both sides, the cannonballs fly close to Ganymede, and hundreds of alien warships shoot dense fine light at the same time.

The defensive net of fine light could not stop the flying cannonballs, and the shells passed through the gaps in the light net, and after hitting Ganymede, they set off a dazzling nuclear light.

The nuclear light illuminated the darkness of space, as well as the alien fleets floating around Callisto, dozens of shells exploded in a matter of seconds, and space was once again covered in darkness, except for the gravel and dust on Callisto, which was flying in all directions, nothing seemed to change.

Callisto is 170 kilometers in diameter, and the yield of nuclear shells is relatively small, not to mention only a few dozen, even tens of thousands of them are tied together and smashed on them, and they can't do anything about Callisto.

But the success of this batch of shells opened the door for the expeditionary fleet, and it was determined that the defense network of the alien fleet could not stop the shells with a speed of more than three kilometers per second.

With this result, the purpose of this battle has been achieved, and Gao Kai's gaze swept over several comrades: "How is it?" ”

"It should be fine." Lu Zuo said.

"Let's get started!"

"Yes, order the formation to go!"

There is a "hangout" on the left and right sides of the Kunlun, and a carrier-based aircraft is placed in each nest, and after receiving the order to leave, all the doors of the nest are opened, and two oversized wooden windows seem to be opened on both sides of the battleship.

A puff of flames erupted from each window, and more than seventy warplanes popped out of the ship at the same time, and the well-trained pilots accelerated towards Callisto as they divided into six groups of exactly twelve fighters each.

The six formations quickly dispersed, and then rushed towards Ganymede as fast as they could.

The distance of more than 700 kilometers is enough for the fleet to increase its speed to 3 kilometers per second.

At the same time, the Penglai, hundreds of kilometers away, also released all the warships, and the target was also Ganymede.

In order to prevent the fighters from being sniped by alien warships, as soon as the aircraft group set off, Gao Kai issued an order to the fleet to saturate the attack, and the ten battleships led by the Kunlun immediately poured artillery fire on the alien fleet at the highest rate of fire.

The turrets placed on the belly of the Helicarrier are firing at full power, with a cannon ejected every two seconds; Missiles flew out of the hive-like nest of improved missiles under the belly of the ship.

The escort Class 024B removed most of the laser turrets and replaced them with regular naval guns, and the bow was firing at Callisto's eight turrets in turn, each firing like a dazzling fireworks.

The artillery fire of the 026 class was even more intense, and dozens of cannons fired shells one after another like a tide.

The firepower of the fleet was also greatly consumed, and in less than a minute, ten battleships fired more than 3,000 tons of shells at the enemy!

If it is on the ground, 3,000 tons of artillery shells is really nothing, but the artillery shells and missiles used by the space fleet are all improved versions that take into account the lack of resistance in the vacuum environment, and the fuel of the missiles and the propellant of the shells have been reduced to a minimum.

And that's just shells, not missiles.

For this battle, Gao Kai did spend a lot of money, and this burst of artillery bombardment alone used up a quarter of the fleet's ammunition reserves.

The speed of the artillery shells is the fastest, and the speed of the missiles is second, but they are much faster than the fighters, Gao Kai did not expect the shells and missiles to kill many enemies at all, but to find something for the aliens to do, so that the aliens would not target the group of aircraft that penetrated the defense.

The saturation attack of the Second Fleet immediately detonated the alien fleet, and the ships fired thin lights at unprecedented speeds, and the vertical and horizontal beams flew up and down, cutting through the incoming artillery missiles.

Missiles with limited speed were inevitably cut by the fine light, and some of the shells were also sliced by the fine light, and the beams of light that quickly cut through the void were like huge lightsabers, cutting back and forth again and again.

There were too many thin lights and too dense, and as soon as the group entered the range of fine lights, more than a dozen planes were destroyed by the flying fine lights.

The atmosphere at the headquarters suddenly became much more solemn.

The consumption rate of fighters is too fast, and according to this trend, before the aircraft group can break through the defense network of the alien fleet, they will be destroyed by the aliens first.

If that happens, the Aerospace Helicopter will probably follow in the footsteps of the gunboats.

Battleships in human history have had a variety of combat modes, but space warfare has only appeared in science fiction works, and no one can tell how the space fleet should be arranged in the right direction.

Gunboats and motherships are the most mature combat modes of mankind, and if neither of these modes can defeat the aliens, I am afraid that no one really knows what to do.
