After the design of the basic electromagnetic gun was completed, Mu Feng immediately entered the system to find the technology and related drawings he had just obtained, and roughly browsed the relevant parameters.

There are many types of electromagnetic guns, and Neptune eventually designed the "coil reconnect gun".

The coil reconnect gun combines the dual advantages of high energy utilization, high mass projectile fire, and railgun can fire ultra-high-velocity projectiles.

The maximum acceleration peak is increased, and the acceleration process is more uniform and stable, with higher speeds, less recoil, and further improved energy utilization.

Because of the unique characteristics of the electromagnetic gun, the muzzle velocity of the shell is adjustable.

From a minimum of less than 1 times the speed of sound to a maximum of 10 times the speed of sound, almost anything in between.

Because the power generation and energy storage equipment are fixed, the maximum range and maximum rate of fire will also change with the change of the muzzle velocity of the shell.

The larger the caliber, the higher the velocity, the greater the energy consumption, the slower the rate of fire, and the more pressure and restrictions on the barrel and ammunition.

Because all kinds of parameters are adjustable and will affect each other, the system only gives a general range, and the specific effect will not be known until the actual test.

Since it is necessary to test the actual machine, it must be produced, and then modified and shipped.

Mu Feng immediately controlled the equipment of the manufacturing center through the system, set up a plan to produce five sets of 155 mm electromagnetic guns and supporting shells, and asked through the spiritual tradition:

"Nanchang, where are you now?"

Nanchang immediately said: "I'm eating in the restaurant of the First Military Port, what's wrong Commander?" ”

"Eat?" Mu Feng subconsciously glanced at the time, and only then did he know that it was already noon, so he immediately beckoned the Neptune and Sirius sisters to the cafeteria, and said to Nanchang at the same time:

"Don't leave after eating, wait for me in the restaurant, I'll go look for you now!"

When Mu Feng and the three of them arrived at the restaurant, Nanchang had already finished eating, and when Mu Feng and the three of them had eaten, they leaned over and sat down opposite, first said hello to the new Sirius, and then asked directly:

"Commander, what is the matter with the three of you looking for me?"

Before Mu Feng could speak, Sirius over there deliberately put on a sinister expression, the corners of his mouth were slightly upturned, with a mysterious smile on his face, he lowered his voice and said:

"The Commander, in order to gain greater strength, is going to perform some dangerous and strange experiments on you, and this experiment will make your hull tremble, and your soul tremble, and you will never forget it."

Neptune next to him followed: "And we will record everything that is interesting, write it into a script, make it into a documentary, make it into a horror film, make it into a tertiary film, tentatively named "The Nightmare That Never Ends." ”

Mu Feng swallowed the beef in his mouth, followed the two of them and one of them with a brain, and said to Nanchang:

"Don't listen to the nonsense of the two of them, just take you to try the specific power of the newly developed electromagnetic cannon."

Nanchang was stunned by Neptune for a while, and after suddenly understanding the meaning of Mu Feng, he jumped up directly and exclaimed:

"Electromagnetic cannon! Commander, you said the electromagnetic cannon was made! ”

Mu Feng nodded: "Well, I just made it this morning, and I'm preparing to test it." ”

After Nanchang confirmed the news, he became even more emotional, stood at the table and stared at Mu Feng and said:

"So when are we going to start!"

Mu Feng waved his hand: "Don't worry, the equipment design is complete, but it hasn't been produced yet, you sit down and wait for a while, we finish eating, and the equipment production should be almost done." ”

"Good good ......"

Nanchang took a deep breath, sat back in his seat, and watched Mu Feng eat with an itchy look.

Battleship mothers are very familiar with weapon systems, and more powerful and excellent weapons have a natural attraction to them.

The epoch-making weapon of the electromagnetic cannon has a fatal attraction for them.

Especially in Nanchang, others have always believed that all-electric propulsion plus electromagnetic cannon is their complete body, otherwise their excessive power system will be wasted.

Due to the great expectation, Nanchang is already very familiar with the structure and principle of the electromagnetic gun, and also knows the huge advantages of the electromagnetic gun compared with the traditional gunpowder gun.

The shell of a conventional artillery is divided into two parts: a propellant and a warhead, which is given the power to fly out by the explosion of the propellant in the chamber.

The propellant and warhead of large-caliber guns are basically stored separately, and the volume of the propellant pack is much larger than the warhead part.

The shell of the electromagnetic cannon is a simple warhead, and the work of propelling the charge is completed by electromagnetic force.

Not to mention the huge power of the electromagnetic cannon, there is a very simple and straightforward benefit after replacing the electromagnetic cannon, that is, there is no need to store the bulky and dangerous propellant kit separately.

Propellants are large packets of explosives, and this thing is the easiest thing to detonate.

It is difficult for the heavy shells themselves to detonate directly, and the detonation almost always starts with the propellant.

Mu Feng knew that Nanchang was in a hurry, so he finished eating as quickly as possible, and then immediately went to the manufacturing center to get two sets of main guns and shells that had just been produced.

Take Nanchang back to his room, let him lie down, and transform her main gun system by himself.

The structure and size of the turret of the electromagnetic gun are very different from that of the traditional artillery, and the main gun ammunition magazine is no longer needed, so the replacement of the electromagnetic gun requires the adjustment of the internal compartment structure, which requires the modification of the hull.

However, the amount of renovation work is not large, and it was completed in ten minutes.

Ten minutes passed almost in a blink of an eye, and Nanchang, who woke up, jumped up directly, feeling the new weapon on his body, with an excited face, and impatiently pulled Mu Feng to the dock.

Neptune and Sirius had to record the specific data of the physical electromagnetic cannon to facilitate future improvements and upgrades, and of course they followed all the way, and the three of them went to sea together on the Nanchang.

The range of the electromagnetic cannon is up to hundreds of kilometers, the strait in front of the port area is not completely straight, and the trees and rocks on both sides of the river can also interfere with radar data.

So the Nanchang sailed all the way out of the strait, came to the ocean, and turned the bow to the north.

Mu Feng let the airport's air police 500 take off, be on alert in the air, and at the same time serve as a global observation mission.

The electromagnetic cannon has a maximum range of several hundred kilometers, and Mu Feng didn't want the helicopter to run for more than an hour to put the target, so he directly found a small island with a distance of about 400 kilometers.

After Sirius had the AWACS aircraft lock on to the island, it marked several target points on the electronic map, transmitted them to Nanchang through a data link, and then announced:

"155 mm electromagnetic gun test, ordinary shells, maximum energy, target 400 km away on the shore of island A on the shore of point A, ready for firing!"

Nanchang's shipwreck projected herself to stand above the bridge of the Nanchang, slowly pulled out the command saber on her waist, pointed far ahead, closed one eye, and the subtle electric light flickered in the open pupils.

And the main gun in the bow of the ship in front of her has already entered a state of storage.

"Charge: 3-2-1, launch!"

At the same time as Nanchang's voice came out, a blazing fire erupted from the muzzle, which was not an ordinary flame, but a plasma produced under high temperature and high pressure.

At the same time, a specially made solid shell was knocked out.

At this time, the velocity of the shell is close to 10 times the speed of sound.

The friction between the surface of the shell and the air creates an extremely high temperature, but it is difficult to dissipate it, and the insulation material and the surrounding air are ionized, forming a layer of high-temperature ionized matter.

The plasma "sheath" is attached to the shell and interacts with the electromagnetic waves, causing a large attenuation of the electromagnetic wave transmission used for communication and then scattering it directly.

Judging from the radar, the target shell is directly "black", "gone", and the radio cannot communicate, which is the "black barrier" state of high-speed aircraft.

Under the influence of air resistance, the speed of the shell gradually decreased, and when it was reduced to less than 7 times the speed of sound, the radar was finally able to observe normally.

But by the time it reappeared in the radar field of view, it was already in front of the target.

The electromagnetic cannon is not a laser cannon, it is not energy that shoots out, it is still a normal shell.

As long as it is a cannonball, it is a parabola, and the trajectory is relatively straight.

When the power decays, it will eventually fall.

The cannon is still able to attack targets outside of sight normally, and it is not just a straight flight all the time.

Mu Feng passed through the AWACS aircraft and looked at the island 400 kilometers away, as well as the target point set by Sirius.

The shells appeared quickly, at a distance of 400 km, but it took less than 5 minutes for the shells to arrive.

At this time, the speed of the shell still exceeded 6 times the speed of sound, hitting a rock the size of a van.

"Boom ......"

With a loud bang, the stone was shattered by pure kinetic energy, and the rubble rolled everywhere.

Mu Feng sighed: "This power is okay, but the distance is too far and the accuracy is almost ......"

Sirius reported with a blank face:

"Test results of ordinary shells with a range of 400 km, missed, deviated from the target by 368 meters, the shells still have a fairly high lethality, continue testing!"

Nanchang clenched his fists vigorously, with an excited face: "This cannon is really powerful!" ”

As for saying that the first shot missed, this is too normal, this is a range of 400 km, and it uses ordinary shells, if it hits, there will be a ghost!

Nanchang continued to recharge and fire according to the test plan developed by the Sirius sisters, and the target was still the stone marked A on the map 400 kilometers away.

Nanchang shot one shot at a time, and after 20 shots, Sirius announced:

"The target remains the same, the type of shells remains the same, now start firing at full speed."

"Understood!" Nanchang agreed, and turned on full horsepower, improving the efficiency of the energy storage and release device of the electromagnetic cannon to the limit, and the shells were continuously fired out one after another.

Because the distance was too far, Nanchang fired a hundred shells in front and back and still did not hit a single shot.

The farthest one was nearly a kilometer away, and the nearest was more than a dozen meters apart.

However, Nanchang, Sirius, and Neptune are all satisfied with these data.

Because the length of a stone the size of a car is only a few meters, if it is replaced by a warship with a length of more than 200 meters, it has already hit a lot of shots.

The Neptune sisters continued to record all kinds of data, and when they felt that the data under one condition was sufficient, they asked Nanchang to adjust the parameters, change the target, and test the rate of fire, range, and hit rate of different magnitudes.

The four of them tested at sea for a whole afternoon, and had a general idea of the various characteristics of the basic 155-mm electromagnetic gun.

There is also a preliminary plan for the further improvement direction of the electromagnetic gun and other application prospects.

Neptune summarized the various relevant information collected, formed a more detailed explanatory document, printed it out and handed it to Mu Feng.
