From sulfuric acid to nitrocellulose, from iron ore to blast furnace molten iron, from home-made ironmaking to oxygen blowing furnace steelmaking, from a few vises to a complete set of mechanical processing equipment, a total of millions of silver dollars were invested to build it from scratch.
The basic industrial structure, tens of thousands of people and more than one hundred people working hard day and night, all finally created today's 'truth'.
The truth that belongs to China was born.
At this moment, staring at the heavy artillery that exudes the beauty of war weapons, Yu Hua is full of pride. He has really done it, and together with his ancestors created a miracle that is unique in human history.
"Go and ask the leaders to come in. Just say that the cannon is ready." Yu Hua stood on the spot, recovered his senses, smiled, and said to the nearest soldier.
The soldier suppressed his excitement, nodded immediately, turned around and ran quickly outside the workshop to inform the leader and others.
After hearing the news that the final assembly of the Red Peony Howitzer was completed, the atmosphere immediately became lively. Smiles appeared on everyone's faces. Without hesitation, they quickly walked towards the heavy artillery assembly workshop.
"Hello, leader." Yu Hua came to the door of the workshop to greet them, greeting everyone who came one by one, with words full of respect.
This comes from the respect in the heart.
The realization of the idea in my mind is inseparable from the support of these big guys. Without the help of the entire organization, it would be impossible to build a heavy artillery, not even a sulfuric acid.
"Classmate Yu Hua, thank you for your hard work." The leader at the top looked at Yu Hua, whose eyes were bloodshot, and said softly with emotion in his heart.
The rest of the people did not speak, but stared at Yu Hua silently. The changes in the base area have an important relationship with the young man in front of them.
First with the secret help of Mr. Zhang San, and then with the full support of the genius Yu Hua and Tsinghua professor Zhuang Qianding, Yu's seven tower technology, rotary coking technology, oxygen top blowing steelmaking technology, electroslag remelting technology...
It is precisely because of these cutting-edge technologies that the northern Shaanxi base area has changed from a poverty-stricken situation to what it is today. Black powder grenades have become TNT grenades, reloaded bullets have become brand-new bullets, and homemade firecrackers have become official in assembly line production. Seized
Mortars and artillery have now become independent production, and everything has changed. The days when we were left behind and relied solely on capture are gone forever!
The changes are so great that it feels like a dream, but it is extremely real.
"This is what I should do, please come this way." Yu Hua said modestly, without too much delay, motioning for everyone to move forward.
The leader nodded, and everyone followed Yu Hua to the front of the red peony prototype cannon.
The huge 105 mm caliber muzzle, the 2415 mm long slender barrel, the dark and metallic barrel, the tapered metal sleeve covering the barrel, and the double-chamber hydraulic retractor arranged side by side, which is stable and reliable.
The mechanical height and steering gear, the heavy breech block, the large off-road load-carrying tires specially designed for the northern region, the iconic slewing bearing and the triangular auxiliary hoe, all elements make up this unique heavy gun.
Three hundred and sixty degrees of shooting, there is no other semicolon, this is the only one.
Everyone quietly stared at the prototype cannon, their eyes in trance, as if they had seen some peerless beauty, and they could not forget it for a long time.
beautiful!
So beautiful!
Regarding the prototype cannon, the leader had already understood it to a certain extent before and had some resistance at this time. However, this was the first time for this gentleman and other army officers to see the Red Peony prototype cannon in a real sense.
The thick muzzle gives an unparalleled visual impact, and the solid gun mount like a strong man is far superior to any 75mm mountain gun seen before.
Just one glance made the military officers present forget Miss Qiwu's grace.
The 105mm howitzer, named after the red peony, the national flower, also has the feel of a Chinese cannon.
"This is our Red Peony howitzer prototype. It has been finally assembled. The main performance parameters are 105 mm caliber, barrel length 23 times the diameter, directional firing range of 360°, high and low firing angles of plus 75° to minus 7°, and a maximum range of 14
Kilometers, the road traction travel speed is up to 40 kilometers per hour, and the field traction travel speed is up to 15 kilometers per hour. It takes about 8 minutes to transform the traveling state into a combat state."
Yu Hua explained in detail like a tour guide, introducing the main performance parameters of the prototype gun: "The regular personnel are equipped with five people. If the situation is urgent, one person can also complete the loading, aiming and shooting work. The maximum rate of fire is 8 rounds per minute, and the combat rate of fire is 6 rounds per minute.
The continuous firing time is about 150 rounds, and the barrel is cooled for 20 minutes. In terms of ammunition, grenades and armor-piercing incendiary bombs are selected as conventional ammunition solutions."
After hearing the words, the leader nodded and expressed approval. The army officers also had no reaction. As the theoretical Party A, they were extremely satisfied with the Red Peony Howitzer and could not find any faults.
The only drawback may be the total combat weight of 1.8 tons.
However, the previously developed Red Star tractor made up for the lack of power of the heavy artillery machine. The off-road capability of the Red Star tractor far exceeded the various towing military vehicles imported by Zhongzheng. After all, this is a serious single-cylinder engine, both in terms of load capacity and
The off-road performance far exceeds that of military vehicles of this era.
Leading in one place, leading everywhere.
Nowadays, everyone is in the standard "boar eating chaff" state, and their understanding and importance of weapon performance parameters is not as important as that of later generations. They only know one thing - the Red Peony Howitzer is very powerful.
The popular understanding is that you can hit far, hit accurately, and hit fast. The combination is - fierce.
"Team Leader Yu, how come the ammunition plan uses armor-piercing incendiary bombs? Isn't it a howitzer?" Another gentleman asked curiously.
"Leader, because of the 23 times diameter barrel, the launch trajectory is extremely straight, and the effective range is about 1,500 meters. To a certain extent, it can take into account the needs of anti-tank operations, shooting vertical targets, armored targets and long-distance fixed targets, such as enemy
Square tanks, bunkers, towers, etc. The 105mm armor-piercing incendiary bomb developed by the Military Industry Bureau adopts a traditional cap design, the armor-piercing part is made of tungsten alloy, and thermite-based incendiary is added to the internal hollow area. The penetration depth at 500 meters is about 110 mm.
The penetration depth is about 90 mm at 1,000 meters and about 75 mm at 1,500 meters. The materials are all high-carbon homogeneous steel."
Yu Hua answered this question: "After penetrating the target, the thermite-based solid incendiary agent will ignite immediately, further damaging the internal structure of the armored target. Of course, this is a theoretical design indicator. Various types of artillery shells have been successfully developed and have not yet been tested in practice."
Penetration-1, this is the third ammunition model of the domestic 105 mm ammunition system. It is based on the structure of the deflagration-1 shell. It is a complete ammunition type, with a caliber of 105 mm × 380 mm, a total weight of 16 kg, and a muzzle velocity of 580 meters per second.
The warhead is made of tungsten alloy material, and the combustion agent is thermite-based combustion agent. The theoretical effective penetration reaches 90 mm per kilometer.
The penetration power of the entire ammunition is not high in the world, but in today's anti-Japanese battlefield...
Sorry, I can only describe it as invincible.
"Good boy, can you lay the cannon flat?" Another gentleman was startled when he heard this. His eyes suddenly straightened and he looked at the 105 mm diameter muzzle. He couldn't imagine the sight of this cannon being held flat to hit a Japanese tank.
The 105mm caliber howitzer is used to hit tanks...
The picture is too beautiful to imagine.
The commanders of the surrounding troops took a deep breath when they heard the words, and then they reacted and felt their blood gushing out, heat rising to their heads, and they were very excited.
Wonderful, it only takes a few seconds. If one shot is fired, the Japanese tanks will be reduced to parts and burned to ashes?
Armor-piercing incendiary bomb, this name is so cool.
The leader asked: "What's the lethality of the grenade?"
"The high-explosive -1 grenade is designed with Soviet-made ammunition, the projectile material is high-phosphorus steel, the TNT charge is 2.8 kilograms, the theoretical absolute killing radius is 8 meters, and the effective killing radius is 20 meters." Yu Hua continued to answer.
"Okay, okay." The leader didn't know what to say. Whether it was the cannon or the ammunition, it was extremely satisfying.
Everyone around was listening intoxicated, as if they were dreaming.
Effective killing radius 20 meters?
This is a number they could never imagine.
"Leader, now that the prototype gun has been assembled, I have applied for prototype gun testing to conduct systematic practical testing of the artillery system and research and development ammunition." Yu Hua looked at the leader and said seriously.
Since the prototype gun test is of great importance, it must be approved by the leadership before it can be carried out. This is a previously established rule.
The leader nodded without any hesitation: "I agree."
