Depleted uranium is a by-product obtained after extracting the nuclear material uranium-235 from uranium metal, which is very common in the waste of nuclear power plants, and its main component is uranium-238, which is weakly radioactive, so it is called depleted uranium, referred to as depleted uranium.

And the Longinus gun mentioned by Commander Zhang is actually a kind of poor shaft ammunition that they have newly developed.

As a weapon material, depleted uranium powder is a flammable and explosive substance that can spontaneously combust at room temperature. When rubbing or impacting, it can be oxidized and burned in the air, and the combustion temperature can reach 10,832 degrees Celsius, which is equivalent to 6,000 degrees Celsius, and a large amount of energy is released and an explosion occurs.

Moreover, the poor shaft projectile with a metal rod made of depleted uranium as the core shows spontaneous sharpness characteristics after hitting the object under the drive of kinetic energy, and the penetration ability is no longer comparable to that of ordinary armor-piercing bullets. As a poor shaft projectile equipped for the Han fighter cannon codenamed 'Weilong', the exclusive number ZTZ-999 was called the small Longinus gun by the young people of the scientific research department of the Xianyang military.

"Of course, as a traditional Han Chinese, for the group of secondary and second young people in the Ministry of Scientific Research, if it is the spear of Longinus, I prefer to call it 'fire dragon spear'."

Commander Zhang's smile at this time seemed to carry a certain relief, this is a kind of successor feelings, for those young men in the scientific research department, he used a word that he just knew, middle two. Although he has been explaining to Ye Hongjin and Song Yanhai, his eyes have not left the big screen for a moment.

Some conventional ammunition is generally equipped with a tracer tube, and when it is shot, you can see a light flying out. But for depleted uranium, it is not needed at all, at speeds in excess of 700 m / s. Depleted uranium can be burned by friction with air! Very, very flammable, and when fired, a clear and bright light can be seen flying all the way to the target.

On the large screen, countless small fire dragons were sprayed out by fighter jets, aiming at a target so small for a fighter jet, and moving quickly, it was probably not only the skill of the fighter pilot's skills that were tested. There are also exceptionally powerful talents.

The sortie was carried out by two squadrons of fighter planes and a bomber group, and after a round of covered bombing, the bomber group of one group had withdrawn first. However, only one of the remaining two squadrons of eight fighters was firing at low altitudes, and this one was undoubtedly the best fighter pilot, and he was the only one who could keep up with the actions of the tall undead skeleton.

The 30mm cannon roared wildly, and the lean shaft bullet slashed a fiery serpent along the path of the undead skeleton. The undead skeleton was clearly aware of the damage the weapon could inflict on him. The speed increased again and again, but it was impossible to escape the pursuit of the fighter overhead.

Of course, it's just that it's just a matter of pursuit, and for fixed targets or large targets, these may not be a problem, but this two-meter-tall undead skeleton is really too much for a fighter jet, not to mention that he is still moving at high speed, and the bullets that pour down with fire are always grazing the bones of the undead skeleton.

Then. The fighter's cannon suddenly stopped, and instead fired a laser-guided missile on the flank. Although in terms of current technology, the guidance accuracy of laser-guided missiles has been improved to 2~3 meters, but for such a strength of the undead skeleton, the error of 2~3 meters is enough for him to get out of the danger zone.

As all the viewers thought, the undead skeleton turned around and broke away from the core explosion of the laser-guided missile, but when his body turned in another direction, he galloped out of the sky, and the fighter's cannon rang out again!

The pilot's accurate estimation of this fighter was, no, predicting the actions of the undead skeleton, he used laser-guided missiles as bait to force the undead skeleton to turn, and based on the previous tracking process, he knew the speed and reaction time of the undead skeleton, and sprinkled countless poor shaft bullets on his landing point.

The undead skeleton was unavoidable, and was hit by the tongue of fire that was sprayed in an instant, Rao is he did a great degree of evasion, but he was still hit by dozens of shots.

When hitting the target, because the depleted uranium is very soft, its head will be deformed, but this deformation has its own characteristics, the head of the depleted uranium bullet will become sharper and sharper, and it will show a very obvious liquefaction feeling, which also promotes the burning of the depleted shell more violently.

The burning depleted uranium caused the temperature in the range of the undead skeleton to rise sharply, and even the temperature at some points almost reached the surface temperature of the sun, even the undead skeleton whose bone was close to jade was frozen at this time, resisting this damage with his undead breath.

In this case, even a meter-thick steel plate would be punctured, and the undead skeleton 'enjoyed' this treatment at this time, dozens of poor shaft bullets scattered all over its body, making it look like a fire skeleton in its whole body.

The low-flying fighter circled for a week, and then returned, and Ye Hongjin and others were waiting for the results on the big screen, this time the Xianyang military was also bleeding, this bleeding was not manifested in the consumption of ammunition and the like, but in such an attack, that area was no longer suitable for living people to enter for decades, or even nearly a hundred years.

After all, the lean shaft is a radioactive element, and according to the military, the area around the depleted uranium bomb hit point, at least 40 meters, belongs to the radioactive contamination zone, just like if you pour soot on the table and slap it down, the dust will fly all kinds and fall farther away.

The most annoying thing is that depleted uranium is generally burned very clean, that is to say, the dust particles are very, very small, breathing such dust will cause heavy metal poisoning in the first time, it can even directly penetrate into the skin from the pores, these dust is inhaled into the body, and after being deposited, it will continue to release energy in the human body tissues, causing extremely dangerous internal radiation. As long as it is inhaled, it is basically impossible to completely metabolize it, that is, as long as it is inhaled, it is basically cancer.

Even if it is the Jindan stage, I dare not say that I am immune to cancer...... No one wants to do this kind of experiment.

It's also a shame that the targets this time are all undead creatures, if it was used on which otherworldly creatures before, the effect is indescribable, but this weapon has always been a forbidden weapon before the invasion of the other world, and the invasion of the other world is extremely fast, and many armies have not had time to react.

This time, the Xianyang military got the first-hand weapon effect information, although the price is that there is an additional restricted area in the backyard of his house with serious radiation exceeding the standard, but this bleeding is worth it, there is the tomb of the Qin Emperor, and so much has happened before, even if it is not bombarded by poor shaft bombs, it will be encircled into the forbidden area, and the radiation will not be difficult for the military to act, at most wear special protective clothing.

"I want to go and see it now!"

After being silent for a moment, Ye Hongjin looked at the motionless undead skeleton on the big screen and spoke. (To be continued.) )
