Knock wonders from the space station

Chapter 137
The entry of the first Polaris ship made the first battalion cheer and cheer, and the sudden expansion of ambition had nowhere to go.

So they decided to postpone the return flight plan for the time being, to find more troubles with bugs, and earn some Stargate secret keys.

In terms of formation, the hammerhead sharks of the first brigade were replaced by Polaris, and the saber formation remained unchanged for the time being.

Lu Feng filled the hangar of the Xinhuo with attack drones, and conducted remote command through the shipboard computer, in order to test their performance against the Vajura Zerg in the next battle.

The formation departs soon.

Because it was still early, Zerg patrols did not appear much in the inner ring.

The first brigade can only guarantee to encounter them if they go deep into the outer ring.

Sure enough, the swaggering No. [-] Brigade was quickly targeted by the bugs. Because it was the other party's territory, two patrols came at once.

Among them were two blood halberd beetles.

"According to the original battle plan, the main gun is locked on the blood halberd beetle!"

The two upper and lower armor plates of Polaris immediately moved to the sides, two S4-sized turrets rose, and the precision muzzle glowing with blue light pointed at one of the blood halberd beetles.

"5 rapid-fire shots, hit!"

The electromagnetic coil in the 75mm gun barrel immediately passed a large amount of current, and the special electromagnetic shell was accelerated to more than ten times the speed of sound, and then fatally fired at the blood halberd beetle in the distance.

Due to the short distance, the blood halberd beetle was hit by the shell almost instantly, without even a chance to react.

The huge kinetic energy directly tore apart the beautiful carapace of the blood halberd, smashed half of its body, and soon died utterly.

Lu Feng obviously didn't expect that the blood halberd would stay like this, but it rushed over in such a daze, not even making an S-shaped maneuver, probably because it hadn't fought a human for a long time.

Because the corpse of the blood halberd was blown away by the projectile, the fire control system was stopped immediately after firing the second shot, saving the time for the electromagnetic gun to dissipate heat.

The other blood halberd immediately became the target of the two 75mm main guns.

Although it began to maneuver crazily and search for cover, the terrifying electromagnetic projectile flew by mercilessly. After the first few rounds failed, the seventh round finally succeeded in killing it.

After killing the leading blood halberd beetle, the remaining dozens of yellow beetles became much less threatening, and they were all reduced to pieces under the intensive human fire.

During the fierce battle, the armor of the Xinhuo was hit by a lot of plasma bullets, and the result was like tickling.

Facts have proved that when the bugs do not launch a siege with a superior number, especially after the commander is killed, the threat they can cause will be greatly reduced, because they lack the necessary individual intelligence.

The battle only lasted 10 minutes before it ended overwhelmingly. Lu Feng got his wish and got two more fragments of the Stargate secret key.

While the drone was cleaning the battlefield, Lu Feng evaluated the situation of the battleship.

It was found that except for the heat dissipation of the two main guns, all other equipment was normal.

It is unavoidable for the main gun to enter the cooling state, but the two 75 guns on the ship cool down very quickly. After a burst of high-frequency shooting, it will not take long to complete the cooling.

Heat dissipation is a consideration for all advanced weapons.

Although the electromagnetic gun is powerful, it has high requirements on materials, energy, heat dissipation, etc. Although it is small compared to energy weapons of the same level, it is still relatively cumbersome to use.

Coilgun is a relatively basic electromagnetic launch system. Its advantages are cheap, simple and durable, and easy to maintain. in weapons.

Like the goblin rifle, it adopts the principle of reconnection gun combining electromagnetic coil and traditional gunpowder firing.

When to use a coil gun and when to use a rail gun, there is a general consensus in the industry, simply speaking, it is based on the caliber.

The 2.0mm standard naval gun with a power level of 75 is at such a critical demarcation point.

In the military field, naval guns above 75mm often use orbital acceleration to ensure sufficient power and accuracy. The huge energy and heat dissipation systems of warships can also better support the play of rail guns.

However, rapid-fire guns below 75mm often use coil acceleration or reconnection, at the cost of sacrificing part of the power and accuracy, in exchange for higher frequency and more stable firing.

Its relatively low construction and maintenance costs are friendly enough to forces that cannot afford to build large ships.

Even on the giant ship of the ancient version of Goblin Heavy Industries, they even frantically equipped with traditional chemical energy artillery with a caliber of 4600mm.

Except for the high-quality gun barrel steel, the rest of the mechanism is simple and the cost is cheap, which can be called the best among all warships of the same level.

This is why Polaris uses coilguns instead of more expensive railguns.

No need!
No matter how awesome your mass-produced frigate is, in the end it’s still a one-shot thing, it’s too advanced to be useless~
Cheap and large quantity is king.

Of course, this only applies to those forces that have no shortage of people or have developed unmanned warships.

Lu Feng thought about the uncertain future of human beings on Earth, and felt that the smallest fleet unit in his future would have to be a destroyer, and all frigates should be eliminated, or unmanned models should be developed.

People can die as little as possible.

……

Because they were fighting in the Zerg active area, this time Lu Feng and the others only roughly cleaned the battlefield, and then hurriedly withdrew.

After returning to the inner ring area, there was a big fight with the Zerg chasing soldiers who followed. This time there were as many as 3 Vajura teams, and it took a lot of work for the slightly tired saber formation to barely cope. , several fighter planes suffered varying degrees of damage.

And Polaris also had a real fight with the blood halberd beetle. The armor was shot twice, but they were all blocked.

The plasma cannon power of the blood halberd beetle can reach up to 2.4, which is the same as the peak defense of the North Star, but the power will be greatly attenuated with the range.

Therefore, as long as the blood halberd does not have the opportunity to fire close to the hull, the blood halberd's long-range attack cannot shake Polaris' defense.

In the end, they were hit by 75 guns one by one.

Although the new crew members were a little confused during the battle, they worked hard to adapt in the later stage, and their performance was okay.

After the battle, the first brigade withdrew a certain distance inward, and then began to arrange drones to repair the hull and replace parts.

All spare parts are directly produced by Lu Feng through the subspace. Now Shentang's ship industry is highly dependent on the subspace, so Lu Feng has to consider the problem of ordinary people's independent maintenance when manufacturing.

That is to say, he needs to follow the construction sequence of the shipyard and realize it bit by bit, leaving a complete maintenance channel and disassembly interface.

Otherwise, he would solidify everything together at once. Although he is not worried about quality problems at all, there is still a possibility of battle damage. At that time, the maintenance personnel will not even be able to dismantle it!

Or make it modular in the future, and just throw it away if it breaks?

Lu Feng fell into deep thought.
