The 105mm Howitzer No. 001 was slowly pushed into the firing range by a few skilled workers. This time, the target was an abandoned house three kilometers away, halfway up the mountain.
The cannonball used was a high-explosive cannonball. The total weight of the cannonball was more than 15 kilograms. The gunpowder alone was 1.5 kilograms.
"Let's begin, Wallaide."
The weather today was not bad. The scorching sun above their heads had also turned the experimental site into a scorching heat. The wind speed was very small, and the impact on the cannonball shooting was almost negligible.
The experienced Haliad slowly raised the angle of the barrel. The ammunition at the end was also loaded. The 105mm howitzer was not a single soldier mortar. It was impossible for one person to operate it.
A high-explosive cannonball was also loaded into the cannon from the tail. After that, the bolt at the tail was tightened. The rubber plug isolated the interior of the cannon from the outside air. At the same time, it had a certain buffer force, which was beneficial to the firing of the entire cannon.
......................................................................................
Then, the ignition device at the tail was activated at the same time. Then, there was a loud sound in the empty experimental field, like a bolt of lightning in the clear sky on a summer day.
Bang!
In Li Yao's eyes, he could only see the howitzer shaking violently.
An orange-red flame shot out from the barrel. The initial speed of the high-explosive bullet was more than 500 meters per second. The theoretical maximum range was close to 10 kilometers!!
At this moment, Li Yao only felt a roaring sound in his ears. The tremendous tremors shook the sky and the earth not far away…
Liu Zhang was also shocked as he watched the first round of test firing. This was too terrifying. If such a large-caliber cannon was used to attack Guangyi, what would the result be?。
Even if it was a defensive trench, if it was hit by such a cannonball, it would be a narrow escape…
Even the impact of a cannonball explosion could shatter a person's body...
The whistling high-explosive bombs drew a perfect parabola in the sky. From the looks of it, this test was a complete success. It seemed like what Walter said was right. If he was given the resources, manpower, and material resources, the various caliber cannons needed by the independent division could be put into production in a very short period of time.
Li Yao and Liu Zhang had already switched to military binoculars. In the lens, the cannonball flying at high speed was about to hit the target accurately.。
In just two to three breaths, they had covered three kilometers.
Three kilometers away, halfway up the mountain, the dilapidated house was blown apart by the explosion of the high-explosive bomb. Li Yao saw the scene perfectly through the military binoculars. He waved his fist in excitement, completely satisfied with the accuracy.
"Beautiful, Horlaide. You're a genius. In just a few months, you've made a 105mm howitzer.。”
He didn't expect that he had really picked up a treasure. No one would believe that someone in the inland of Da Qian, Western Sichuan, already had a self-developed howitzer...
Moreover, it could be produced independently.。
From raw materials to design techniques, they were all in Guangyi's hands. He did not need to look at the expressions of the foreign powers. He could continuously produce them in the rear and send them to the front line during wartime...
"Huataide, continue the test firing. Test a few more rounds!!”
"Boss, as you wish, this will be the greatest cannon design ever. Even the Krupp Cannon Factory can't design it!!”
In the next half an hour, the shells were loaded and reloaded. From three kilometers, four kilometers, and even five kilometers, the results of each round of test firing were not bad, except for the five kilometers test firing, where the margin of error was somewhat affected. Of course, the vertical height of the hill was also a factor.
At two o'clock in the afternoon, in the office of the First Cannon Factory, Li Yao was also frowning. The birth of any new weapon would always have its own flaws. The design of the new howitzer would definitely have its flaws.
" I'm sorry, Li. The steel produced by the steel factory is used to make the barrel. To be honest, Boss, the steel-making technology here is still lacking compared to Hans. The new howitzer is perfect in terms of firing speed, stability, and weight, but I just checked the wear and tear of the barrel…"
" To be honest, Li, according to the degree of wear and tear, a howitzer might explode after firing 20 shells…"
Wallaide's expression was also a little ugly. After all, the steel factory here was only a small steel factory. The 75mm mountain cannon barrel was relatively durable because the internal power was not so violent. However, after the caliber was increased to 105mm, the power of the explosion increased exponentially. The quality of the steel was also a problem.
"You mean the quality of the steel in the steel mill is not up to standard?？”
Li Yao thought of the crux of the problem. The construction of the First Steel Plant was only to meet Guangyi's basic demand for steel. Military products such as cannons had many different requirements from civilian products.
"It can't be completely said that the quality is not up to standard. However, Boss, you also know that the firing conditions of the 105mm howitzer, the strength and hardness of the steel pipe need to be re-designed.!”
Li Yao understood it, too. He nodded. If it was any other problem, it might take a long time, but to improve the strength of steel, he only needed to add some other metals. There must be a complete design plan in the civilization war machine.
"Alright, I'll give you an answer tomorrow. As long as we can solve the problem of the steel's strength, the 105mm howitzer can be mass-produced immediately.。”
"According to the current production capacity of the First Cannon Factory, we can produce four howitzers per month. Of course, this is after the problem of steel materials is solved. If the production of new alloy steel is slow, the production of howitzers will naturally be affected.”
In the evening, Li Yao returned to the county town. He had already exchanged some new alloy steel designs and combinations from the Exchange Mall of the civilization war machine. These things would be sent to the cannon factory of Wallaide in a few days.
