Gao Kaixuan's acceleration at this time was not a whim, but he had this idea for a long time.

The reason why the fleet slowed down in advance was to slow down in order to fight a decisive battle with the enemy, and now it is accelerating again in order to gain the initiative in the battle.

In general, both speed and altitude superiority in air combat are important, and although there is no atmosphere in space, many truths are universal.

To put it simply, if the speed of the battleship is too slow, it will become a live target for the enemy, and it will be so passive that it can no longer be passive; Too fast and staggered, and it takes hours to turn around in a split second, and then spend the same amount of time flying back for the next round of attacks.

If it is a long journey that has not had time to slow down, then the time consumed by each round of charge must be calculated in months, and there will be nothing to fight at that time, so the two sides will rush back and forth to play, it is estimated that they will not be able to rush a few times, and the fuel will not be able to withstand it first.

At present, both sides have the intention of fighting a decisive battle, so they invariably maintain an appropriate speed, but within the appropriate speed range, they must compete for the speed advantage as much as possible.

There is another point that is very critical - although the dogfight between warships is also a close-range dogfight, the so-called far and near refer to the space scale, and the actual distance is not in meters, but in kilometers, and the straight-line distance of tens of kilometers is short, and it is not surprising that hundreds or even thousands of kilometers are short.

The kind of plot in the movie that is often several kilometers and more than ten kilometers, facing each other with naval guns, and even hitting each other is difficult to stage in reality, unless the commanders of both sides have their brains pumping at the same time, and they have to fight each other in the form of collision.

Battleship ramming was a tactic in the era of sail warships, and the means of long-range attack at that time were very limited, and the combat distance between the two sides was only a few hundred meters, and ultra-close distances and relatively slow speed were the prerequisites for using ramming tactics.

Since the beginning of modern times, there has never been a record of colliding and sinking an enemy ship in naval warfare between countries, and even if they want to collide, they must first pass the level of naval guns and torpedoes, not to mention entering the era of over-the-horizon combat, where they cannot even see enemy ships, and it is even more impossible to talk about ramming.

The characteristics of space battles are that the distance is long and fast, even if the two sides deliberately slow down the speed, the relative speed per second is often 180 meters, plus the battleship is heavy and huge, it is not easy to turn and overcome inertia, and it is not so easy to collide with the enemy ship, so the probability of collision between warships is negligible.

The combat distance of the two sides depends on the maximum range of the weapon, and the long arm is naturally more advantageous.

At this point, the human race with a lot of weapons undoubtedly has a great advantage, which is why there are few warships in the Nanzhou ship group, but Gao Kai is not worried at all - you can't beat me, but I can punch the flesh, what else is there to worry about?

Gao Kai thought so and did so, taking advantage of the fact that there was still some distance between the enemy and us, all the warships opened fire with all their might, missile after missile, super shotgun after super.

On the surface, the main force is missiles, but in fact the main force is super shotguns, and countless finger-sized steel balls are laying a wide net in front of the fleet, just waiting for enemy planes to drill into it...... That's right, enemy aircraft, not enemy ships!

At present, the relative speed of the enemy and us is too slow, the steel ball is too small, and it will not play much role in smashing on a heavily armored battleship, but it is different for the insect machine in the sky, this thing is a crispy skin, no matter how slow the steel ball is, it is much faster than a bullet, I dare not say that a steel ball kills an insect machine, but as long as it hits, it is enough for the insect machine to drink a pot.

Think about what it looks like for a person to be hit by a bullet, and you can think of what the result is when the insect machine is hit, the insect machine is not a lifeless machine, and it will be affected a little bit if you take a hard hit.

With this in mind, the Nanzhou ship group began to attack from a distance of 3,000 kilometers, and by the time the distance was shortened to 2,000 kilometers, it had already exhausted 50 percent of its missiles and one-third of its super shotguns.

The aliens were not idle, their fleet had not stopped spreading, and the faster insect swarms even opened up like a large net, heading towards the Nanzhou ship group.

Although the aliens can't see the super shotguns, they have suffered too many losses, and they have long guarded against the Nanzhou Fleet, and the alien fleet is scattered so much just to avoid the super shotguns.

As for the insect machine in the sky, the aliens don't think it's anything, because the insect machine is relatively small, and the chance of being hit by a super shotgun is not as high as that of a battleship.

The aliens believe that the insect swarm tactic is a very effective means of warfare, and the cost of the insect machine is far lower than that of the battleship, so they use the insect sea tactic very obscenely, preparing to flood the human fleet with the insect swarm.

According to the calculations of the Nanzhou, the enemy dispatched no less than 30,000 insect planes, which were evenly distributed to the Nanzhou ship group, and each warship could be divided into 1,500, even if only one-tenth of them successfully hit, it would be an out-and-out air disaster for human warships.

Think of what a terrifying and appalling sight it would be for more than a thousand snake lizards to rampage through the battleship.

At this moment, the radar screen of the Nanzhou is full of flashing red dots, and the front, as well as the front, the up, down, left and right sides are all occupied by red dots.

Gao Kai was also nervous, he suddenly felt that it was not a good thing to spread the fleet, and if the distance was too far, it would be equivalent to giving the enemy a chance to break through, and it would be difficult for the aliens to fall into the arms!

Immediately, he had an alien smirking in his mind.

Fortunately, it was not too late to realize the problem, and he immediately ordered: "Order all ships to move closer to me, leave the insect machine alone, and concentrate fire on the enemy ships...... Also, order all carrier-based aircraft to take off, and each ship to fire at the swarm first! ”

After receiving the order, the aviation troops, which had been prepared for a long time, immediately set off, and the fighters ejected the battleships one after another, and then the aircraft group was divided into several waves, facing the direction of the most dense insect planes.

While the ships were moving closer to the Nanzhou, they continued to fire missiles and super shotguns at the swarm.

Enemy ships and enemy planes keep firing fine lights, but all the targets of fine lights are missiles, there is no way, the steel balls are too small and too small, even if aliens can see them, they can't intercept them, not to mention whether they can see it or not, it's hard to say.

The distance between the two sides finally entered two thousand kilometers, and the insect swarm was one step ahead, and the distance between the two sides and the Nanzhou ship group was less than a thousand kilometers.

At this moment, a bug machine was hit by a super shotgun, and the elytra, which had been vibrating endlessly, became slower and slower, and soon stopped completely.
