"This is the ammunition storage facility of our 1601 Coast Guard ship!"

Qin Chuan led several people to the ammunition depot and opened the safety protection gate, introducing the way.

The No. 1 ammunition storage facility is about 40 meters long and 10 meters wide, originally located in the area where the main transmission shaft of a warship is located.

But due to Qin Chuan's modification of the coast guard ship to be fully electric propulsion, the 40 meter long transmission shaft was dismantled.

So it's only natural that this place has been converted into an ammunition storage facility!

As soon as they entered the ammunition depot gate, General Cheng and others were shocked by its size.

What exactly does the coast guard want to do with such a large ammunition depot?

This is a question that constantly arises in everyone's heart!

You are a law enforcement officer!

Not for war!

Is it necessary to exaggerate the ammunition storage facility like this?

However, as they entered the No. 1 ammunition depot and saw the shells displayed inside, they suddenly understood the reason why this ammunition depot was designed so large.

Because the shells placed here have a length of 4.8 meters and a caliber of about 300 millimeters!

"Is this a shell fired by an external electromagnetic railgun?"

Seeing such a large shell, Captain Liu Hong had some doubts about life.

Because the 130 naval gun weighs only 27 kilograms of shells, compared to the shells in front of us, it seems like a toy!

It's hard for him to imagine that an electromagnetic railgun can shoot this type of shell out 2000 kilometers?

"This is a specially designed scramjet projectile for electromagnetic railguns!"

"Seeing everyone staring at the shells," Qin Chuan said.

But after Qin Chuan's words, everyone present clearly became even more confused.

"I have only heard of a scramjet engine, mainly used for hypersonic aircraft!"

"Are there any scramjet shells?"

"If my memory is correct, the prerequisite for starting a scramjet engine is at least three Mach speeds or above, right?"

General Cheng once again raised doubts.

"That's right, in order for a scramjet engine to work, it must be given a speed of at least three Mach ahead!"

"But what if we use an electromagnetic railgun to catapult the projectile to a speed of six Mach?"

"When I was developing electromagnetic railguns, I found it difficult to solve the overload problem of shells' acceleration exceeding six Mach."

"Once overloaded, all electronic components used for navigation in the projectile will be disabled!"

"So I changed my thinking and designed large caliber and heavy shells, using electromagnetic railguns to only accelerate the shells to Mach 6."

"And the remaining work will be completed by the scramjet engine on the shell..."

Qin Chuan explained.

Through Qin Chuan's simple and straightforward explanation, General Cheng also instantly understood Qin Chuan's intention and design principles.

He had a sense of enlightenment and looked at Qin Chuan in shock.

Because he discovered that Qin Chuan is truly a military design genius!

Although the scramjet engine may sound high-end, it has a simple structure, light weight, and a very low price.

The conditions that require three Mach to start are very harsh and difficult to achieve.

But if it is used on the shells of electromagnetic railguns, combined with reasonable design, it may really reach a range of 2000 kilometers!

"General Qin, could you please explain in more detail the principle of this electromagnetic railgun shell?"

Chief Cheng asked eagerly.

"No problem, chief!"

"If we want to achieve a range of 2000 kilometers for electromagnetic railguns, the shells will have to spend most of their time flying outside the atmosphere, approaching a vacuum trajectory!"

"Its peak height is about 450 kilometers, and its re-entry speed is about 17 Mach!"

"Firstly, we use an electromagnetic railgun to launch the projectile, giving it a launch speed of around six Mach!"

"There are folding wings on the shell before and after firing, which will unfold. The front wing is equipped with a Beidou guidance kit to drive deflection, achieving precise guidance!"

"The projectile's head has two conical oblique shock waves that sweep through the inlet lip. When the Mach 6 incoming flow passes through the shock waves, it is compressed and deflected twice into the inlet."

"A small portion of these compressed air will enter the combustion chamber and ignite to form a certain pressure of combustible gas. These combustible gases come out of the pipeline and mix with air at Mach 6, which will be ignited like a match in a Category 15 typhoon, forming a shock wave."

"At this point, the combustion chamber valve increases or decreases pressure to control the shock wave velocity, making it equal to the Mach number of the inlet airflow. At this point, the flame front conducts forward, forming a stable detonation zone!"

"In this way, the scramjet engine can accelerate for a long time after the projectile is fired by the electromagnetic railgun, and ultimately exceed Mach 17 before the projectile leaves the atmosphere, flying towards the trajectory vertex!"

"..."

Qin Chuan explained all the principles and processes of electromagnetic railgun launch.

After listening to Qin Chuan's account, General Cheng was already shocked beyond measure!

Because this design scheme is absolutely feasible in principle and has no problems.

In addition, the electromagnetic railgun and shell are right in front of us, which means that Qinchuan has really developed an electromagnetic railgun with a range of 2000 kilometers!

This will be an absolutely stunning weapon!
