Rebirth 76: Industrial Internet Empire

Hong Tao's heart suddenly sank to the bottom. If, as Yang Mo said, West Germany's rocket launcher technology has developed to this point, it would be almost a dimensionality reduction blow to our Type 67-107 rocket launcher...

Yang Mo continued to kill people and punish his heart: "But another West German was obviously much calmer. He said: Don't underestimate the power of the Soviet-made BM-21 "Hail" 122mm self-propelled rocket launcher, except that its maneuverability is not as good as our Lars In addition to rocket launchers, the firepower and range are not inferior, and this is a previous-generation product that has begun to be exported to South Asia and Eastern Europe."

Yang Mo deliberately fabricated this lie that was not very logical but could not be verified because he was familiar with the history that was about to happen and he wanted to do something for this country...

Our main battle artillery equipment, the Type 67 107mm rocket launcher, was completely suppressed by the Vietnamese BM-21 in the border conflict. After suffering a big loss, we learned from the experience and got an original version with the help of a friendly country in Eastern Europe. bm-21, based on this, developed the classic 81-type 122mm rocket launcher, which showed great power in the subsequent battle between the two mountains.

Yang Mo's mentor was once invited to participate in the improvement work of bm-21. Yang Mo still remembers the way his mentor talked about this humiliating history in class:

"Classmates! The level of military equipment represents the future of a country. In a big country with a population of one billion, rocket launchers have been completely suppressed by a small country that we selflessly assisted a few years ago. If you fall behind, you will be beaten! This is the case for every metallurgical, mechanical Shame on practitioners…”

When it comes to the emotional part, the gray-haired instructor couldn't help but burst into tears.

Hong Tao's mind was completely disturbed by Yang Mo's words, and he asked nervously: "Is bm-21 so powerful?"

Yang Mo scratched his head: "I don't know the specifics. By the way, they also talked about the advantages and disadvantages of bm-21."

"What are the advantages and disadvantages?" Hong Tao and Wang Haiyang asked in unison.

Yang Mo thought for a while before saying: "They said that the bm-21 has a fast launch speed, strong firepower, extremely short combat preparation time, and can quickly switch from marching state to combat state. It uses the Ural truck chassis and has excellent off-road performance."

Hong Tao asked in a deep voice: "Doesn't bm-21 have any flaws?"

Wang Haiyang waved his hand and said domineeringly: "Battles still have to be fought by people. No matter how powerful their equipment is, can they be more powerful than the Allied Forces of the Seventeen Nations? Aren't they beaten to shame by us?"

Yang Mo nodded and said: "Yes! Those West Germans also said that the bm-21 has the biggest flaw. Although the range can reach up to 20 kilometers, the shooting accuracy is low and the stability is also very poor. When the rocket is launched The fire is too bright and can easily expose the location of artillery positions. So you don’t have to worry too much. If these fatal flaws are exploited, they can kill them..."

"How to use it?" Hong Tao asked.

Yang Mo continued: "Set a fake tactical target trap to tempt them to concentrate their fire attacks. The best attack distance of bm-21 is between 12-15 kilometers. This way, the approximate location of their artillery positions can be initially calculated and calculated in advance. A good shooting angle. It takes about 21 seconds at the fastest for the bm-40 to fire 18 rockets. We have enough time to cover their artillery positions with several rounds of artillery fire before they move. If the terrain reconnaissance is accurate, we can even guess The best diversion route for their rocket launchers to carry out extended artillery attacks..."

Hong Tao frowned and said: "But our 67-type 107 rocket launcher only has a range of about 8.5 kilometers, and each gun truck only has 12 barrels, and its maneuverability is very different. This is why we came to you to purchase special steel. "

Yang Mo thought for a while and then said: "If you just want to improve on the 107 rocket launcher, it doesn't make much sense to install the 63-type 107 mm 12-barrel rocket launcher on an off-road vehicle chassis. At most, it can only become an infantry weapon." There is no problem in suppressing artillery and dealing with the opponent's mortars and infantry artillery, but there is a generation gap that is difficult to make up with other people's bm-21, and it is almost beaten in all directions!"

"What do you think?" Hong Tao asked with a solemn expression.

Yang Mo said straightforwardly: "In one step, we will launch 21 40mm rocket launchers directly based on the bm-122!"

Hong Tao smiled bitterly and said: "Why don't we want to develop a rocket launcher that can compete with the bm-21, but with our materials and technical level, it is difficult to imitate a 40-tube 122mm self-propelled rocket launcher in a short period of time. This way The rocket launcher, even without ammunition and personnel, will almost certainly weigh more than 20 tons, which is an extreme test for our load-bearing trucks, both in terms of chassis and power..."

Yang Mo pondered for a moment and then said: "Not necessarily. Using high-carbon chromium high-temperature resistant bearing steel can reduce the thickness of the barrel. As for the chassis, if high-strength, damage-resistant steel is used, it can also be slimmed down and the powertrain can be reduced in weight. In terms of cost, if key components such as gearboxes and crankshafts are provided by our Zhiyuan Group, there will be a lot of room for improvement, and the maneuverability will not necessarily be worse than that of the bm-21."

"Can it really reach the level of bm-21?" Wang Haiyang asked a little excitedly.

Yang Mo nodded: "If everything goes well, the range, accuracy, maneuverability and other aspects of performance will at least not be worse than the bm-21!"

Hong Tao's face also showed some excitement, but more of it was still anxiety. He knew that the manpower and material resources required to develop a piece of military equipment were far more than just a few of them could achieve by sitting here and discussing!

Yang Mo thought for a long time, looked at Hong Tao and Wang Haiyang and asked: "Do you still use electric arc furnaces to smelt gun barrel steel?"

Hong Tao nodded and said with some embarrassment: "I know that most foreign countries now use electroslag remelting furnaces for secondary smelting. We have introduced this equipment, but the technology is not perfect yet!"

Yang Mo explained: "The secondary smelting of the electroslag remelting furnace is very necessary, which can effectively remove non-metallic impurities in the steel, control the content of non-metallic elements such as sulfur and phosphorus, and make the molecular structure of the rough material closer."

Hong Tao nodded.

Yang Mo continued to ask: "After the rough blank is forged, how do you usually process the inner bore of the gun barrel? Do you have a rotary precision forging machine?"

Hong Tao smiled bitterly and shook his head: "We mostly use simple machinery combined with manual operations to rifling the inner wall of the gun barrel. How can we afford a rotary precision forging machine? That thing has always been banned equipment in Western countries, and it is impossible to sell it to us……"
