The 300-mm rocket launcher, if used in a conventional charge, is probably capable of holding 150 kg of high-explosive charges mixed with TNT.

If this part of the charge is completely replaced with all-nitrogen explosives, the explosion power can be increased to the equivalent of 12,750 kg of TNT.

More than twelve tons of TNT is enough to blow up several skyscrapers!

Plus 300-mm rockets have almost six or seven meters long booms.

Enough to be used as a heavy ground-penetrating bomb.

In general, the concrete thickness of a permanent underground command post at the divisional brigade level will not exceed five meters.

These super bombs with the power of more than a dozen tons of TNT are enough to blow up the entire underground command post into the air dozens of meters in the air! ——

The desert of the north, among the rolling hills.

A very special weapons test is underway.

"Xiao Zhang!"

"You're always giving me problems!"

"Last time it was a nuclear bomb test site, and this time it's a super-large test site."

The old chief looked at Zhang Xingyang, who looked ordinary in front of him, but was actually a genius, and said with a smile.

"You, you can give me a whole new trick every time!"

Zhang Xingyang was also a little embarrassed, this part of the work was actually nothing to do with the old chief, but he bothered him every time.

"There's really no way around it this time."

"We can't handle such a large testing ground on our own."

The projected range of the rocket may reach up to six hundred kilometers.

Anything can happen at such a distance.

If, in the process, the engine of the rocket stops, it falls directly from the sky.

If you fall into no man's land, it's better to say something, at most you need to lose money.

If it falls into a residential area, it's over, and with the power of all-nitrogen explosives, it can easily blow up half a block of buildings!

Moreover, at this time, most of the residential areas in China were still small buildings with not too high floors, and no high-grade concrete was used.

A super bomb with 12 tons of TNT power can easily push half a block peacefully!

That's why Zhang Xingyang asked the old chief to find a test site with a large enough length.

"How much high-nitrogen explosives did the rockets you test this time contain?"

After experiencing the last time, the old chief asked Zhang Xingyang this question very seriously before the experiment.

Avoid saying it a little, but it's actually a Himalayan joke.

"One of the warheads had no charge in them, but they were equipped with an inertial guidance system."

"The second shot was a mixture of black sorkin and high-nitrogen explosives, a total of 148 kilograms."

"The last shot is also the high-explosive charge we are going to try, and it is all high-nitrogen explosives."

Zhang Xingyang honestly told the old chief all the charges of the three rockets in this experiment.

"Your guidance technology is good, what kind of accuracy can be achieved this time."

The old chief was well aware of the strength of the Rocket Research Institute in guidance technology, and asked jokingly.

"Our guidance technology is still very immature in terms of miniaturization."

"It's nice to be able to achieve an accuracy of up to 100 meters."

At this point, it is really not that Zhang Xingyang is modest, but that their guidance technology has not been studied much in terms of miniaturization, after all, the platforms used before are all large platforms like space rockets.

"With the power of all-nitrogen explosives, this accuracy should be enough, right?"

"150 kilograms of all-nitrogen explosives are enough to destroy a target within 500 meters."

However, the old chief didn't particularly care about the problem of low accuracy.

Even if the error reaches 100 meters, the power of high-nitrogen explosives can still complete the strike on the target.

"Chief, the preparations for the weapons test are all done!"

At this time, a soldier in a green camouflage uniform walked over.

"Then let's start testing, Dean Zhang."

The old chief replied calmly. Then the leading work of the test was handed over to Zhang Xingyang.

The first to be tested were guided rockets without a single charge.

Because of the importance of this experiment, three different rocket launchers were used for each of the three rockets.

This is to prevent any accidents that could affect the experiments of other rockets.

Long rockets spewed orange flames from the rocket launcher and then sliced through the sky at breakneck speed.

Only a white cloud trail was left on the horizon.

A rocket launch is different from a rocket launch because the rocket is too small to fit a communication device inside.

Therefore, in the process of its flight, there is almost no way to observe it except for chasing it in the sky and running on the ground.

And because the thrust of the new solid-fuel rocket engine has been greatly improved, the speed of the new 300-mm rocket has reached Mach 7.6.

At this time, there is no aircraft in the country that can keep up with such a high-speed object.

So after the rocket is launched, it can be considered to disappear from the whole world.

Even a large radar monitoring station on the ground would have a hard time detecting this thirty-centimeter-thick and six-seven-meter-long object.

But fortunately, Zhang Xingyang has long considered the problem of monitoring, and dozens of optical observation points have been arranged along the flight trajectory of the rocket.

Judging by the cloud trail of the rocket's flight, whether its flight trajectory has deviated.

The results of one observation point after another were constantly reported to Zhang Xingyang.

It is gradually fitted into a curve in the computer, showing the trajectory of the rocket in the sky.

"Looking at this trend, the accuracy may be a little higher than what we have calculated before."

Just when Zhang Xingyang muttered to himself about the results of the data.

The rockets have accurately hit targets at a distance of 450 km.

"The deviation between the impact point and the target point is less than eighty meters!" The communicator who was in charge of communicating with the target point gave a result that made everyone happy.

This shows that the guidance technology of the Rocket Research Institute is still good.

"Go ahead and test the second rocket!"

Zhang Xingyang did not give everyone much time to celebrate, but immediately began the test work of the second rocket.

Just like the first one, the second rocket was still crossing the sky at a very high speed.

Less than two minutes later, the news of the target point came.

"The deviation between the impact point and the target point is about 90 meters."

"Because of the high power of the rocket explosion, the initial impact point cannot be accurately marked."

"The damage range of the rocket reached three hundred meters!"

Even with only half of the high-nitrogen explosives, the rockets have shown much more power than before.

At this time, without Zhang Xingyang's prompts, everyone very consciously began the test preparations for the third rocket.

After nearly two minutes of intense waiting.

On the other end of the communication, there was a voice that almost trembled.

"The deviation between the impact point and the target point cannot be estimated!"

"What do you mean?"

"The rockets are missing? Off-track? ”

Zhang Xingyang, who was in a hurry, directly grabbed the intercom and asked quickly.

"No, no!"

"The target point is completely gone!"

"The rockets completely flattened the entire hill more than ten meters high at once!"

"Now the target point is completely dusty, and I can't see anything clearly!"
