Sun Erwei looked helpless: "Wang, I think you should follow Skinner's suggestion and choose the Bofors anti-aircraft gun instead of the M1..."
"I said!" Wang Xuexin interrupted Sun Erwei: "Bofors is not suitable for us!"
Sun Erwei spread his hands: "Tell me the reason!"
"Our artillery is not as good as the Japanese!" Wang Xuexin replied: "You should know this. If our army is equipped with such medium and short-range anti-aircraft guns, it will only become a target for the enemy's artillery!"
Sun Erwei had to admit that Wang Xuexin was right. Bofors did not have much survivability when artillery firepower could not suppress the enemy.
Sun Erwei did not expect this because Yingjiang had never worried that the artillery firepower was not as good as the enemy's.
but……
Sun Erwei smiled and asked: "So, do you think the M1 anti-aircraft gun is suitable for you? Do you think that as long as the range is far enough, you can avoid the enemy's artillery? Do you think the M1 anti-aircraft gun has no problem?"
Sun Erwei walked back and forth in front of Wang Xuexin twice, pretending to hate iron but not steel, and asked again: "Do you know why we don't equip m1 in batches?"
"No, I don't know!" Wang Xuexin replied.
This is true. Wang Xuexin didn't know much about anti-aircraft artillery. He even learned about this artillery after listening to Skinny's introduction.
"You don't know anything, Wang!" Sun Erwei shook his head and said, "Let's put it this way, its range is 19 kilometers, do you know what this means?"
Wang Xuexin was stunned for a moment, and then he immediately understood...beyond visual range!
Then Wang Xuexin thought of another thing: radar.
Things beyond visual range are usually used in conjunction with radar.
The difference between anti-aircraft guns and howitzers is that long-range howitzers are actually beyond visual range, but this beyond visual range can be compensated for by the cooperation of artillery observers.
The reason is that long-range howitzers deal with enemy infantry and artillery. These targets move slowly and the artillery has time to react.
The target of anti-aircraft artillery is aircraft... The speed of fighter planes in this era generally reaches more than 400 kilometers per hour, which is about seven kilometers per minute. Some are even faster. For example, the Japanese Zero Fighter has a top speed of 533 kilometers per hour.
If the method of artillery observers is used to deal with fighter planes, several processes are required: observation, calculation, and then sending the coordinates to the anti-aircraft artillery unit, and then the anti-aircraft artillery unit adjusts the elements according to the coordinates, adjusts the time of the artillery shells, and launches the artillery shells...
This process can take a few minutes at most, and by this time the target has already flown out of the bombing range and may have even completed the bombing and left.
This is also the reason why the anti-aircraft gun given by Mao Xiong has a range of only 4 kilometers, and the Bofors range is only 7 kilometers... Without radar cooperation, ultra-long range is meaningless.
Although Wang Xuexin knew this, he did not answer because he knew that these things are commonplace in modern times, but they are black technologies in this era. If he had answered, he would not know how to explain it.
Sun Erwei continued: "We can only observe targets about four kilometers with the naked eye, Wang! The telescope can barely reach six kilometers... and this is under good weather conditions!"
Wang Xuexin nodded.
Taking the 14.55-meter wingspan of the Jiazi 97 Heavy Explosion as an example, displaying the entire area four kilometers in the air is equivalent to looking at a grain of rice from a distance of one meter. It would be difficult to detect as long as there is a little cloud or fog.
Sun Erwei leaned over and asked Wang Xuexin: "Well, Wang! The range of the M1 is 19 kilometers. How do you hit those invisible targets?"
Then Sun Erwei stood up again and said with full pride: "We can do it because we have something called radar. Our way of combat is to use radar to detect enemy aircraft dozens of kilometers away, and then use
This kind of anti-aircraft gun destroys the target on the road, understand? For this reason, we have even developed an anti-aircraft gun with a range of 25 kilometers..."
Sun Erwei stopped talking when he said this, because he thought that Wang Xuexin would not understand even if he continued to talk, so there was no need to waste words, as long as Wang Xuexin understood that this anti-aircraft gun was not for them to use.
Then Sun Erwei joked: "Maybe you can also buy our radar! But I think this is not something you can afford!"
This is not a joke by Sun Erwei. Although the radar of this era is bulky and not good enough, it is the most advanced equipment of this era, so the cost is very high. At this time, a land-to-air radar system in Yingjiang requires six vehicles to carry, at least
It takes millions of dollars.
At the same time, Sun Erwei also believed that there was no need for the Eighth Route Army to equip radar. It was just a few anti-aircraft guns. It was a huge waste to equip the radar.
Wang Xuexin nodded and said: "You are right, Sun Erwei! But I still want to buy m1!"
Sun Erwei looked at Wang Xuexin in confusion and asked: "Why? You didn't understand..."
"No, I understand!" Wang Xuexin interrupted Sun Erwei: "But... although we don't have radar, we know where the enemy's planes will appear! That's enough!"
Sun Erwei was stunned for a moment, then opened his mouth and nodded slightly: "You mean, your tank?"
"Yes!" Wang Xuexin explained: "If there is anything in the Eighth Route Army that is worthy of bombing by the Japanese, it must be the tanks. If the Japanese must bomb our tanks, it means that wherever our tanks appear, the Japanese planes will eventually
Where did it appear? So, do we still need radar?”
Sun Erwei couldn't help being stunned.
There is nothing wrong with this. The Eighth Route Army is not like the recalcitrant army. The recalcitrant army has an airport, a warehouse and a power station... The only valuable thing of the Eighth Route Army is this tank unit, and the Japanese have transferred the 97 heavy explosives for a very clear purpose.
It is used to deal with these tanks, especially the T34.
In this way, the location of the Japanese plane is almost certain.
If this is the case, the M1 anti-aircraft gun with a range of 19 kilometers can certainly play a role... They can adjust the time of the shells in advance and even conduct test firings, just waiting for the Japanese fighter planes to appear.
"But..." Sun Erwei said: "The devils will know this tactic once you use it..."
"What can we do if we know?" Wang Xuexin asked, "Why don't you bomb our tanks?"
Sun Erwei was asked.
What this means is that even if the Japanese know it, they have no choice but to bomb or not bomb.
If you bomb, you have to face the anti-aircraft barrage preset by the Eighth Route Army. If you don't bomb... that's exactly what the Eighth Route Army wants.
Then Sun Erwei asked again: "What if the Japanese bomb the anti-aircraft guns?"
"We will not let them succeed!" Wang Xuexin replied: "First of all, it is not easy for them to find the exact location of the anti-aircraft gun. Secondly, with this medium-caliber anti-aircraft gun that can be towed by a car, we can hide it in the air-raid shelter in just one minute.
!”
Sun Erwei thought for a while, then nodded and said: "Okay, Wang! You win, this tactic is no problem!"
