Rebirth of the 1980s: The Military Industry Empire

The work of calibrating the gun is very important. The British L11 tank gun can hit targets at a range of four kilometers, relying not only on the advantage of the 120mm rifled gun but also on precise calibration.

If we were installing that kind of 120mm rifled gun now and required hitting a target at three kilometers, Qin Yang would never dare to play like this. The shell could miss by more than ten meters.

Even the 69-3 tank at the national range, which was modified with the British TSFCS simple fire control system with a digital ballistic computer, has an 80% first-round hit rate at one kilometer, which is inseparable from the credit of gun calibration.

But we don't need to shoot that far! The 59 tank at hand only had its L7 tank gun replaced. The sighting equipment hasn't changed; it still uses the 1959-style gunner's sight, which is a copy of the old Maozi's Т Ш 2-22 sight. It's a thorough optical sighting system, and it's good enough to guarantee accuracy within 500 meters.

Beyond 500 meters, luck is more important than skill.

What is being demonstrated to the superiors this time? Not how high the accuracy is, but how strong the armor-piercing shell's performance is! So, at most, we'll hit a target at 500 meters, and a simple gun calibration will be enough!

When Squad Leader Zhang put the flashlight into the barrel, his face was excited: "Engineer Qin, you even know this kind of gun calibration method? When I first became a tank soldier, an old tank soldier who had participated in the war taught us to do this. I originally thought it was outdated, but I didn't expect you to still be using it!"

Optical gun calibration was an old method in the past. Now, using it again gives Squad Leader Zhang a familiar feeling.

"Of course. Regardless of whether it's outdated or not, it works. If we had a gun whose trajectory matched our shells, it would be more intuitive to fire it directly in the barrel," Qin Yang said.

"That's right! That's also what the old tank soldier said."

The crowd stood outside, watching all of this in surprise.

The light from the flashlight passed through the barrel and shone on the wall a hundred meters away, creating a spot of light on it. Engineer Qin was actually going to use this method to calibrate the gun?

Today, they drank a lot of Moutai wine, and everyone's minds were a little muddled. They could still guess what was happening: Leader Pan was planning to get Qin Yang drunk and delay the gun calibration, so there would be no test firing tomorrow! Qin Yang would embarrass himself in front of many leaders and become a joke in the military industry system.

But looking at this situation, just like the installation in the morning, Qin Yang had already been confident. The Moutai wine provided by Leader Pan was wasted!

Qin Yang sat inside the tank, skillfully rotating the gunner's sight, aligning the sharp-angled mark inside with the center of the light spot. He fine-tuned a few knobs and quickly calibrated the gun.

"No, this kind of gun calibration is too rough!" Gun-making expert Zhuang Shuren said: "Directly aligning the sight with the light spot means defaulting that the trajectory is straight! This armor-piercing shell was just made by Factory 960, and the trajectory characteristics are unknown. Is it okay for him to adjust it like this?"

Anyone with a little common sense knows that due to the Earth's gravity, whether it's a bullet or a shell, it flies out in an arc, gradually falling downwards. Adjusting the sights on a rifle is to make the muzzle rise, the farther the distance, the more it rises. Tank guns are the same. To hit a target on the same horizontal line, the muzzle must also be raised to make the shell fly upwards first, then fall down, so that it can hit the target.

But now? The default trajectory is straight. How can this work?

"Yeah, if it flies away, it would be a waste. One shell costs tens of thousands!"

Amidst the discussions, Qin Yang climbed out from inside: "Okay, it's adjusted. We'll go to the tank range tomorrow for test firing! Leader Fang, you're welcome to come and inspect tomorrow!"

That afternoon, news about the 59-modified tank's upcoming test firing spread quickly.

In the office, Leader Han heard the news reported by his secretary, thought for a moment, and said: "So fast? Is this news accurate?"

"Yes, we have called Factory 960 to verify, and Leader Fang is over there."

"Okay, arrange the itinerary for tomorrow and go take a look!" Leader Han said with great interest: "By the way, call the superiors and see if our old leader has time to come and see. He is also very concerned about the development of our tank forces!"

Inside Institute 208, a group of people were also discussing.

"This Factory 960 is really strange. They installed the L7 tank gun in half a day. No one would believe it if you said it!"

"That's right, this Factory 960 is really awesome. The light heavy machine gun they recently developed is said to be lighter than the weight required by the superiors and has high accuracy. We thought they were focusing all their energy on the development of the light heavy machine gun, but we didn't expect them to just be doing it as a side project, and now they're starting to play with guns!"

"How exactly did they do it?"

"So, are they going to enter the heavy weapons industry? If they keep messing around in the light weapons industry, we'll be out of a job!"

"That's right, let those gun-makers have a headache. Shall we go see how it is tomorrow?"

"That's right, we must join in the fun!"

In an office on the third floor, Old Duo was listening to Leader Pan's spittle-flecked narration of the matter.

Finally, another Hongqi sedan drove over. Secretary Song got out and looked at Leader Han who had just arrived: "The old leader has something to do, so he won't be coming. He instructed me to come and see. Our own armor-piercing shells are going to be test-fired. This is the most exciting thing. I heard that these armor-piercing shells are very powerful, twice as powerful as our 59 tank armor-piercing shells?"

Leader Han nodded: "Yes, if today's test firing is successful, then we can be tough in front of foreigners. We don't need their armor-piercing shell technology, they will have to ask us for help!"

"By the way, I heard that it was Factory 960, which makes guns, that developed it?"

"Yes, recently, Factory 960 has been creating miracles frequently! Everyone says that Factory 960 has produced a military industry genius."

"Genius? What's his name?"

"Qin Yang! Huh, where did Qin Yang go? I haven't seen him all this time!"

Leader Pan was also at the scene, but his position was too low, and he could only be on the outermost edge of the crowd. At this time, listening to the exchanges of the big leaders, he was secretly happy. The greater the hope, the greater the disappointment!

He also inquired and confirmed that Qin Yang and the others had been drinking until dark yesterday, so Qin Yang definitely didn't have time to calibrate the gun!

Rumble… At this moment, the roar of the tank transporter came.
