Goliath-class factory ship.

Fu Qinghai stood in front of the experimental table, with the space ape Shi Lan sitting on his shoulders. Fu Qinghai pointed at the row of firearms of different shapes on the table and introduced them one by one:

"AR2 pulse rifle, from the Half-Life universe."

"M41A2 pulse rifle, from the AVP universe."

"SWS Electric Pulse Rifle, from the Dead Space universe."

"Kusar Klaw pulse rifle, from the Elysium universe."

The first two were obtained by trading with reincarnations in the tavern in Jacob Town, and the last two were found in the Ishimura's armory and seized by Lin Yu in his previous reincarnation world.

Shi Lan jumped off Fu Qinghai's shoulder, stood on the experimental table, picked up a pulse rifle and looked at it carefully.

Although he didn't understand all this universe stuff, he knew that these guns did not belong to the human empire.

"The pulse rifle, as far as I know, is an advanced firearm that uses a dual compound propulsion method, with both propellant combustion and expansion propulsion and electromagnetic coil acceleration."

"According to my tests, these guns are more powerful than laser guns and automatic guns, but not as powerful as bolt guns. This is mainly due to the caliber of the ammunition and the power of the coils."

Fu Qinghai said to Shi Lan.

The so-called "power" here is only a vague and general concept, because the lethality of live ammunition weapons comes from kinetic energy, while the lethality of laser weapons comes from high temperature, so the damage effects caused to different targets are different.

The biggest difference between the pulse weapons in the science fiction concept and ordinary electromagnetic coil acceleration weapons, also known as "Gauss weapons", is that they do not abandon the traditional launch mode.

This pulse firing mode is designed to address the problem of slow firing rates of most electromagnetic coil-accelerated weapons. "Gauss weapons" have a long range, high accuracy, and great power, but their firing rates are often low.

The chance encounter with the young Cawl some time ago reminded Fu Qinghai that the Great Magus Cawl did more than just create the Primaris Space Marines. He also equipped the Primaris Space Marines with brand-new weapons: MK10 power armor, improved bolters and plasma guns, and innovative anti-gravity armored vehicles.

Therefore, if Fu Qinghai wants to compete with Cawl, he has to design special weapons and equipment for the new alien space marines he developed. The MK8 counter-insurgency power armor is already available, so he can also start considering bolters and plasma guns.

If special warheads are not used, the power of ordinary explosive shells is not enough to penetrate the frontal defense of power armor, but they can penetrate weak parts such as helmets, joints and gaps.

That is why the Alpha Legion developed the Deadly Strike Bomb specifically for use in the civil war between Space Marines.

With the technical reserves of the feather gun in hand, Fu Qinghai gradually came up with some ideas of his own on how to further enhance the power of explosive weapons. These ideas required the cooperation of the space monkeys to realize.

The new weapon research and development plan was officially launched:

Pulse Bolter.

"My initial idea for the pulse bolter is this: use the traditional two-stage propulsion mode of the bolter weapon as the main mode, supplemented by the electromagnetic coil acceleration mode, add a battery to the magazine, see if the bullet can be designed as a caseless bullet, and see if the inner wall of the barrel can be rifled."

Fu Qinghai made a request to Shi Lan.

The space ape thought for a moment and said,

"Not only do we need to add another battery, we also need to increase the length of the barrel."

"Yes."

Fu Qinghai had anticipated this.

Traditional bolters are very compact and short weapons for Space Marines, which has both advantages and disadvantages.

In the real world, many countries have gone to great lengths to improve individual weapons in order to shorten their length to facilitate the transportation and deployment of mechanized troops.

However, a barrel that is too short also means unstable trajectory and poor accuracy. The MK2 Kohl-type bolt rifle is much longer than traditional bolt guns.

Whether it is a coil or a magnetic rail, if you want to use electromagnetic acceleration technology, the barrel cannot be short because a certain stroke is required to accelerate the bullet.

"The structure of a pulse bolt gun designed in this way will be a bit complicated."

Shi Lan reminded.

"It doesn't matter. This is a Space Marine weapon, not an Imperial Guard weapon. It's okay if it's a little complicated."

Fu Qinghai said.

Are the structures of the later-generation grenade launchers with genetic locks on the grips, sights on the backs, and built-in ammunition counters simple?

While Shi Lan was talking to Fu Qinghai, he had already disassembled all the guns on the table into parts. After studying them carefully, he looked up and said to Fu Qinghai:

"I will make a prototype gun within three weeks."

"very good."

Fu Qinghai nodded approvingly.

First, we have a prototype gun, then we gradually improve and finalize it, and then we consider mass production scale manufacturing and cost reduction, following scientific research and development rules, step by step.

The verbal cooperation agreement between Fu Qinghai and Shi Lan is very loose and free. "Fun" is the greatest pursuit of the space monkey. If Shi Lan feels that it is boring to follow Fu Qinghai one day, he can leave at any time and Fu Qinghai will not stop him.

But with a constant stream of new technologies coming in from other universes, it might be hard for space apes to get bored.

…

Fu Qinghai had wanted to study electromagnetic acceleration technology for a long time.

Because traditional propellant propulsion technology ultimately has its limits.

Only a single-minded religious scientific research organization like the Mechanicus would cling to traditional shooting methods.

The technological lower limit of the human empire's individual weapons is not the laser weapons equipped by the Imperial Guards, but automatic weapons. Laser weapons actually have a very high technological content, but automatic weapons are really simple and crude.

The automatic weapons of the Human Empire are exactly the same as the gunpowder firearms of the late 20th and early 21st centuries in the real world. Simply put, they are weapons that use propellants to accelerate metal bullets for continuous firing.

Lumberjacks, autocannons, assault guns, and even ship-borne and land-based macrocannons all fall into the category of automatic weapons.

Many people would wonder, why is the human empire still using such backward firearms when it is already in the interstellar age?

Three reasons:

First of all, the enemies faced by the Human Empire during the Great Crusade were not all technologically advanced alien heretics. There were also many barbaric and feudal worlds whose technological level was still in the era of cold weapons or even earlier. To retake these places, using explosive bombs and plasma would be a bit excessive in power and cost, so automatic weapons were just the right choice.

Secondly, automatic weapons have a simple principle and technical basis, and can be produced in many technologically underdeveloped worlds. They can be equipped in large quantities for low-end garrison forces such as the Planetary Defense Force (PDF) to quickly form the most basic combat capability.

Finally, although the technical principles of automatic weapons are not complicated, the propellant in the bullets is not ordinary yellow gunpowder and black gunpowder. High-performance propellants bring greater chamber pressure and require stronger barrel materials. Other science fiction universes have begun to study coils and magnetic rails, while the Human Empire lacks technology but makes up for it with materials. It uses science fiction materials to enhance the power of traditional weapons. For example, the propellant produced in the Huangquan No. 8 Forging World is of the best quality.

In addition, although both are weapons that use electromagnetic force (Lorentz force) to propel projectiles, electromagnetic coils and electromagnetic tracks are actually quite different. The main difference between the two is:

Electromagnetic track weapon: the projectile is sandwiched between two parallel rails, the two rails are connected to a power source, and the current flows through one rail to the projectile and then to the other rail to generate a magnetic field. The magnetic field interacts with the current to generate a strong Lorentz force that propels the projectile forward, reaching a very high speed - theoretically up to sub-light speed.

Electromagnetic coil weapons: The barrel of a gun or cannon is made up of many coaxial coils of the same caliber, and the bullet or shell is also embedded with coils. Current is transmitted to the first coil of the barrel to form a magnetic field, and the coil on the projectile induces current. The magnetic field and the induced current interact with each other to push the projectile forward. When the projectile reaches the second coil, this process is repeated continuously, passing through the third, fourth, fifth coils... until the last coil, the projectile is gradually accelerated to a very high speed.

Compared with the track, the friction between the projectile and the barrel of the coil is smaller, the projectile mass can be larger and the speed can be faster, but the power supply complexity of the coil is much greater than that of the track. Therefore, although the electromagnetic coil is a more advanced technology in theory, the electromagnetic track is a more mature case in application.

As for the principles of these two types of electromagnetic acceleration, everyone knows them. These are basic physical principles that are known in the real world, not to mention the science fiction universe like Warhammer 40K.

But when it comes to practical applications, especially weaponized applications, it is not that simple.

In the real world, homemade electromagnetic coil weapons can make a skewer fly twenty meters away, which is not lethal at all. The U.S. Navy invested in the development of electromagnetic rail weapons many years ago, but has not achieved any results so far.

In the Warhammer 40K universe, the physics of electromagnetic acceleration is of course well known to the Adeptus Mechanicus, but the Imperium of Man has not been able to fully apply this technology because such weapons face many problems in practical operation. The limitations of this technology include the incredible amount of energy required to propel the projectile along a track or coil, and the huge heat dissipation generated in the process.

There is a huge gap between understanding the principles and applying them in military applications.

In the Warhammer 40K universe, Fu Qinghai is very sure that among the major camps, the only one that can achieve weapon-grade application of the two electromagnetic acceleration technologies is the Tau Empire.

The Tau Empire's research on railroad weapons was not accomplished overnight. Early railroad weapons were too large and could only be mounted on combat uniforms or hammerhead sharks. They were not considered individual weapons at all, but rather serious vehicle-mounted weapons. It was not until the second dome expansion that the Tau Empire's Earth Clan scientists, inspired by the power of the Human Empire, worked hard and devoted themselves to research, and finally miniaturized the railroad weapons for individual soldiers.

Only then did he take out something like a rail rifle.

From Fu Qinghai's perspective, the Tau Empire's rail rifle still has very obvious flaws. A pack of batteries can only support three to four shots, which means that a magazine must be replaced every three shots. The firepower density is very low and the logistical requirements are very high.

But what was the result?

Terrifying power.

The Astartes hated rail rifles, because Space Marines hit by heavy rail rifles would be smashed into pieces with their armor - even their gene seeds could not be recovered!

In the original novel about the Skitarii, it was clearly mentioned that Belisarius Cawl drove his mechanical ark to the front line of the Damocles Gulf war zone, where the Tau Empire and the Empire of Man were at war, just to understand how the Tau Empire overcame the technical difficulties of these two electromagnetic acceleration weapons.

Judging from the latest official novel, Great Sage Cawl should be in a state of half understanding at present - the railgun has been built, but the railgun has not yet appeared.

…

"Khan, I have heard many snippets about the 'Goliath-class factory ship' in the astropathic communication recently."

In the captain's room, Xia Long was reporting to Fu Qinghai.

"Huh, as expected."

Fu Qinghai narrowed his eyes slightly and said.

The Goliath-class factory ship is slow-moving, thin-skinned and large-filled, and is the best fat meat in the eyes of the Chaos forces. Those poor traitors who escaped into the Eye of Terror dream of owning a large-scale forged ship of this level.

A Goliath-class factory ship left Mars and left the solar system. Such a huge ship is naturally very conspicuous and will definitely not be hidden from the eyes of those who are interested. Fu Qinghai suspected that many people had already set their sights on this ship.

"Let them come."

Fu Qinghai smiled and said.

"Besides that?"

"A distress signal from a rogue trader claiming to be from the Ultramarine. He is currently being besieged by orc pirates and is requesting support from the nearby Imperial fleet."

Xia Long paused for a moment, then continued:

"I asked for follow-up information and received no response."

"Where is the location?"

"Calisis Star Region, Jossian Border Region, Ekorich Galaxy, the spatial coordinates are..."

Xia Long reported the location coordinates, which were very clear from the star region to the sub-star region to the galaxy and space coordinates.

"Hmm... Tsk."

Fu Qinghai smacked his lips and fell into thought.

Then he casually turned on the holographic projection in front of his desk and adjusted it to the three-dimensional map of the entire star region. The blue projection slowly rotated in front of him. Fu Qinghai glanced around, then turned on the communicator and said to it:

"Tracy, come to the captain's room."

Fu Qinghai reported the coordinates confirmed by the astropath to the navigator and asked:

"If we modify the route now and head to this location, how long will it take?"

Tracy made some mental calculations and replied:

"Expect it to take an extra week."

Fu Qinghai nodded:

"Okay, let's go and take a look."

......

　The content of this chapter is a bit hard science fiction, not so space opera. First of all, I would like to apologize to the book friends who find it boring. Regarding the electromagnetic acceleration technology, I actually plan to open the copy world of Warhammer 41K later, and then slowly tell you when I encounter the Tau Empire, and tell you the story in combination with the plot. But some time ago, a book friend insisted on looking up some vague terms such as "linear acceleration" in the original novel, and based on this, he insisted that I was wrong, saying that the Mechanicus had electromagnetic coil weapons... Originally, I didn't intend to pay attention to him, but he went to Bilibili and said everywhere that I was wrong. I couldn't stand it, so I had to release these things in advance.

　　The core logic of these people is still the same: because the Human Empire rules the galaxy, the Human Empire must have mastered certain technologies, and because the Mechanicus has all kinds of technologies, it is impossible that they don't even have "basic" technologies like electromagnetic acceleration - these are all very stupid logics, reflecting that their views on the world are too simplistic, which is often referred to as "three incomplete views". Later, I will slowly tell you why this logic is wrong, and I hope that you can find some small gains in an online novel.

　　I have always said in previous chapters: Bolt guns are not the solution to sniper rifles. After reading today's chapter, many book friends should have guessed what the sniper rifles equipped by the protagonist's regiment are.
