Knocking wonders from the space station

The entry of the first Polaris ship made the First Brigade cheer and cheer, and there was nowhere to put down the suddenly expanded ambitions.

So they decided to temporarily postpone their return plan to cause more trouble with bugs and earn some Stargate keys.

In terms of organization, the Hammerhead Sharks of the First Battalion were replaced by Polaris, and the Saber formation remained unchanged for the time being.

Lu Feng filled the Xinhuo's hangar with attack drones and controlled them remotely through the ship's computer in order to test their performance against the Vajura Zerg in the coming battle.

The formation set off soon.

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

The First Brigade can only guarantee encountering them if it goes deep into the outer ring.

As expected, the arrogant First Brigade was soon targeted by bugs. Because it was the opponent's territory, two patrol teams came at once.

Among them are two blood halberd beetles.

"According to the original battle plan, the main gun is locked on the Blood Halberd Beetle!"

The upper and lower armor plates of Polaris immediately moved to both sides, and two S4-sized turrets rose up, with their precise muzzles 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 surged with a large amount of current, and the special electromagnetic gun shell was accelerated to ten times the speed of sound, and then fatally shot at the Bloodhalberd Beetle in the distance.

Since the distance was not far, the Bloodhalberd Beetle was hit by the cannonball almost instantly, without even a chance to react.

The huge kinetic energy directly tore into pieces the beautiful carapace of the Blood Halberd and blasted half of its body into pieces, and it soon died.

Lu Feng obviously didn't expect that the blood halberd would stay like this. It rushed towards it without even making an S-shaped maneuver. Maybe it was because he hadn't fought with humans for a long time.

Because the Blood Halberd's body was blown away by the projectiles, the fire control system was stopped just after firing the second shot, saving time for the electromagnetic gun to dissipate heat.

The other Blood Halberd immediately became the target of concentrated fire from the two 75mm main guns.

Even though it started to maneuver crazily and looked for cover, the terrifying electromagnetic projectiles still flew past it mercilessly. After the first few shots missed, the seventh shot finally succeeded in killing it.

After killing the leading Blood Halberd Beetle, the remaining dozens of Yellow Beetles became much less of a threat and were reduced to pieces under the intensive human fire.

During the fierce battle, the Xinhuo's armor was hit by many plasma bullets, and the result was like being scratched.

Facts have proven that when bugs do not launch a siege in superior numbers, especially after the leader is killed, the threat they can pose will be greatly reduced because they lack the necessary individual intelligence.

The battle only lasted for 10 minutes and ended in a one-sided manner. Lu Feng got two more star gate secret key fragments as he wished.

Taking advantage of the opportunity for drones to clean the battlefield, Lu Feng assessed the situation of the battleships.

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

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

Heat dissipation is an issue that all advanced weapons need to consider.

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

The coil gun is a relatively rudimentary electromagnetic launch system. Its advantages are that it is cheap, simple and durable, and easy to maintain. In the low-quality field, the power of the coil gun is not too different from that of the rail gun. Overall, it is more cost-effective, so it is often used in small-caliber electromagnetic fields.

In weapons.

For example, the Goblin Rifle uses the principle of re-shooting that combines an electromagnetic coil with traditional gunpowder firing.

There is a general consensus in the industry about when to use a coil gun and when to use a rail gun. Simply put, it depends on the caliber.

The 75mm standard naval gun with power level 2.0 is at such a critical dividing 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 system of warships can also better support the performance of orbital guns.

Rapid-fire guns below 75mm often use coil acceleration or reconnection, sacrificing some power and accuracy in exchange for higher frequency and more stable firing.

Its relatively low cost of construction and maintenance is also friendly enough to forces that cannot afford to build large ships.

Even on the ancient version of the giant ship of Goblin Heavy Industry, they were even frantically equipped with a 4600mm caliber traditional chemical energy cannon. What stood out was a large-capacity cannon.

In addition to the excellent gun barrel steel, the rest of the mechanism is simple and the cost is low, making it the best among all warships of the same class.

This is why Polaris uses coil guns instead of more expensive railguns.

No need!

No matter how awesome you are as a mass-produced frigate, in the end it will still be useless if it is too advanced~

Cheap and large quantity is the way to go.

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

Lu Feng thought about the uncertain future of mankind on Earth, and felt that the smallest unit of his fleet in the future would have to be destroyers. The frigates would either be eliminated or unmanned models would be developed.

People should die less if they can.

…

Because they were fighting in a Zerg activity area, Lu Feng and the others only briefly cleaned the battlefield this time and then evacuated in a hurry.

After returning to the inner ring area, they had another big fight with the Zerg pursuers. This time, there were as many as three Wajura teams. The slightly tired Saber formation took a lot of effort to deal with it.

, several fighter planes suffered varying degrees of damage.

Polaris also had a real fight with the Blood Halberd Beetle, taking two hits on its armor, but was completely blocked.

The power of the Bloodhalberd Beetle's plasma cannon can reach up to 2.4, which is the same as the peak defense of Polaris, but its power will decrease significantly with the range.

Therefore, as long as the Blood Halberd is not allowed to get close to the hull and fire, the Blood Halberd's long-range attacks will not be able to shake the North Star's defense.

In the end, they were shot down one by one by 75 guns.

Although the new crew members were a little confused during the battle, they worked hard to adapt in the later stage and performed well.

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

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

In other words, he needs to follow the shipyard's construction sequence and implement it bit by bit, leaving complete maintenance channels and disassembly interfaces.

Otherwise, he will solidify everything together at once. Although he is not worried about quality problems at all, battle damage is still possible, and the repairman will not be able to dismantle it at all!

How about making it modular in the future and throwing it away if it breaks?

Lu Feng fell into deep thought.
