Since Lao Tang had robbed all the scenes, Bai Yi didn't need to stay in the heavy firepower company anymore, so after lunch, he packed up and prepared to return to the artillery position in the rear.

Although the scenery on the return trip was very beautiful, Bai Yi was still very depressed, but he was soon relieved, after all, he did not play a big role in the development of rocket range extender bombs.

It was just a development direction that was determined before going to North Korea, and the specific development was completely completed by Stuttberg and other German experts.

And these German experts were as early as 1941 for Na~~! ~~ Germany developed the world's first rocket range extender projectile, and successfully applied it to the SFH-18 150mm howitzer, creating a maximum range of 19 kilometers.

Although at the end of the war, special ammunition such as rocket range extender was gradually removed from the German army's arms procurement list because of factors such as difficult manufacturing, low ammunition power, and high production cost, the relevant technology was completely retained.

And with the captured German experts to the cold Siberia, and then to China, and finally in the Baiyun factory to be reborn into the mass production of new ammunition.

However, compared with the 150mm rocket range extender during World War II, Stuttenberg has made considerable improvements to the same type of ammunition produced by the Baiyun Factory, the most important of which is to significantly increase the range.

From the original 19 kilometers, it has been upgraded to 22 kilometers.

Compared with the initial maximum range of 13.3 kilometers of the SFH-18 150mm howitzer, it has been nearly doubled, which is unimaginable during World War II, because at that time, even if the gun was more than 200mm, it was only a range of more than 20 kilometers, and there was no 150mm level gun that could reach this level, otherwise the entire World War II could be rewritten.

But only a few years later, only with the old technology of World War II, the old ones have been rejuvenated with amazing combat capabilities, which really made Stuttberg and other German experts beat their chests and sigh with emotion, saying why they didn't think of such a simple and effective way to improve the performance of artillery?

In fact, it is not that German experts can't think of a way to increase the range of artillery, otherwise there would be no rocket range extender, but the problem is that after they have rocket range extenders, they fall into the paradox of range and power.

Because the rocket extended-range projectile is to sacrifice the charge of the shell to make room for the rocket engine in the rear, it is to want the projectile to have a long range, reduce the charge, and increase the storage space of the rocket immediately.

But in this way, the power of the shell will inevitably be greatly reduced, and it is not even as powerful as a 100 mortar shell, which is not even as good as a fart in the fierce European theater of World War II, so there is no point in achieving an astonishingly large range.

However, in order to ensure the power of ammunition, the rocket of ammunition must be compressed, and the so-called long-range is only empty talk, because the range of those few kilometers increased will not play much role at all, and it is precisely because of this that the German rocket range extender will become a chicken rib and will eventually be abandoned by the German army.

The Baiyun Plant also encountered the same problem when it began to develop rocket range extender bombs, so much so that Stuttberg and others suggested that instead of wasting time on this thankless ammunition, it was better to focus on the development of the next generation of artillery, and the range solved from the source was better than the immediate effect of opportunistic shortcuts on ammunition.

In this regard, Bai Yi, who was still presiding over scientific research in Baiyun Factory at that time, asked rhetorically: "Since the rocket range extender is a special ammunition, why do you have to drill the horns of ordinary charges?" Why not try special charges, special fuses? ”

As the so-called authorities are obsessed, Stottenberg and the others are not unable to think of other special charges, but they are just trapped in the shackles of ordinary grenade charges and cannot extricate themselves, because of this, when they listen to Bai Yi's words, it is equivalent to opening another window above their heads, and a new world will open to them.

Eliminate special charges and use the newly developed and lightweight white phosphorus charges.

Abandon the traditional bump fuze and delay fuze, and use a more dexterous and simple electrostatic proximity fuse to detonate to increase the killing effect.

Plus the structure of the artillery shell rocket, which the German experts were already familiar with.

In this way, the most basic technical framework has been established for a new generation of near-explosive white phosphorus rocket range extender projectile.

As for the related manufacturing, it is not difficult for the Baiyun Plant, not to mention that there are no less than six bases of 150mm artillery shells in the scrap steel imported from the Soviet Union, but in terms of the most critical white phosphorus charge and electrostatic fuse, the Baiyun Plant has accumulated rich manufacturing experience in the production of 37mm close-fire anti-aircraft shells and 80mm white phosphorus incendiary bombs.

Turning to the 150mm rocket range extender projectile is just a small problem of increasing the amount of charge and modifying the circuit direction, as for the artillery rocket engine, because of the manufacturing experience of the 40mm individual rocket launcher, so although the processing accuracy is higher, it is not much of a problem.

It is precisely because of the mature technology and technology used by the Baiyun Factory that at the end of April, the new rocket range extender was developed and put into production, and in less than a month, 240 rocket range extender bombs were produced, which met the ammunition of six SFH-18 150mm howitzers.

When a 150mm rocket range extender fired from 22 kilometers away exploded in the air above the target at the test site on the west side of the Baiyun Factory, and dozens of scarecrows below were burned to ashes by the flying white phosphorus, it was not difficult to understand why those German experts beat their chests.

Because there is no advanced technology in this ammunition, there is no genius creativity, some are just the integration of mature technology, but what is created is an absolute killer weapon that is enough to change the battlefield situation, which makes those German experts who are respectful on the surface, but still arrogant in their hearts, how not to be impressed and annoyed.

It is no wonder that Stuttberg sourly sighed after the test launch of the 150mm rocket range extender bomb: "Germany does not lack rigorous engineers and ideas that transcend the times, but what is lacking is a natural military genius like Bai Yi!" ”

If Bai Yi could hear Sternberg's words, he would definitely get great satisfaction, but unfortunately, when people said this, he was already in North Korea, and finally had a few opportunities to show himself, but he either met a strongman like the head of armaments, or he met a bastard like Lao Tang, who you brought and forced me to pretend.

Thinking about it, I can only surprise the Americans as Old Tang said!

While thinking about it, Bai Yi's car had already driven into the dense forest of Lenghuang Mountain, where the six scattered German-made SFH-18 150mm howitzers had already raised the muzzle of the black hole high, Bai Yi glanced at it slightly, and just nodded with satisfaction with the position layout of the artillery cadets, and felt that the ground under his feet trembled like an earthquake.

Immediately, the deafening explosion broke through the barrier of more than ten kilometers and poured into every corner of this artillery position, Bai Yi calmed down, immediately picked up the telescope, glanced at the large rising gunpowder smoke and fire in the distance, and couldn't help but say: "Is this the beginning?" ”
