Rebirth of the 1980s: The Military Industry Empire
#109 - Chapter 109 Tank Gun Misses Target
Da da da!
The gunshots continued to ring out on the firing range, the spent casings from the automatic rifles constantly ejecting.
Unlike yesterday, where they flew one or two meters away, this time, due to the angled trajectory, they only flew out a dozen centimeters before falling, and even then, they flew forward and upward, posing no threat to anyone near the shooter.
"Solved, it's really solved!" Old Wang exclaimed with immense emotion: "The problem that we've been struggling with for so many days was actually solved by a few words from Engineer Qin!
Engineer Qin is too amazing!"
"Yes, Engineer Qin is the most amazing person I've ever met!" Wu Hao said with feeling, then looked towards the distant machine gun emplacement.
The Type 89 heavy machine gun was still undergoing R50 value determination.
"Distance of 1000 meters, R50 value of 0.63 meters!" the tester said excitedly: "This machine gun's accuracy is too high!
Our previous heavy machine guns should be completely phased out!"
Half the weight, and even higher accuracy!
This kind of heavy machine gun isn't just suitable for mountain troops; even regular troops would be greatly enhanced by it!
"There are still many tests to come; they all need to be passed," Qin Yang said modestly: "Our heavy machine gun is still temporarily…"
Boom!
Just then, a booming sound came from afar.
Even though it was far away, the eardrums were still pierced, buzzing.
"This is…" Qin Yang paused for three seconds, then made a judgment: "L7 tank gun?"
"Engineer Qin, you really are amazing, knowing it's an L7 tank gun just by listening!
Our domestic Type 69-3 tank is currently…" Yang Zhenhua stopped there, after all, saying any more could leak secrets.
As the top person in charge of the state firing range with the highest level of secrecy, Yang Zhenhua's awareness was also very high.
Qin Yang smiled and said nothing.
These things were secrets in Yang Zhenhua's mouth, but to him, they were nothing at all.
Back when the country was newly founded, the relationship between the motherland and the Old Russians was still very good, so they introduced the famous T-54A tank, and then built the 617 Factory on the grassland.
Little swallow, wearing colorful clothes—this popular children's song is actually about the construction of the 617 Factory back then: We built a large factory and installed new machines.
In 1959, the new tank officially rolled off the production line and was named the Type 59.
At that time, this tank had advanced world-class capabilities.
The country went into full production, producing tens of thousands of them.
Later, the relationship with the Old Russians broke down, and tank technology stagnated.
Although the Type 69 tank was improved in the 1970s, there was no significant difference; it was just a simple upgrade, and the most critical problem remained unsolved: the limited power of the tank gun.
The Type 59 tank's D10T 100mm rifled gun only had an armor-piercing capability of 140mm, while the frontal protection of the Old Russians' mainstream tanks had already been increased to over 200mm!
The main force in the country was still the Type 59 tank.
After contact with the West, China introduced the L7 tank gun and installed it on the Type 69 tank.
The prototype vehicle was called the Type 69-3, and after being officially finalized in the mid-1980s, it was named the Type 79 tank.
The L7 tank gun had unlimited potential.
In the 1960s, the initially used L28 armor-piercing projectile, also known as the American M392 armor-piercing projectile, could penetrate 127mm deep into a target placed at a 60-degree angle 800 meters away, which, converted to a vertical target, would exceed 250mm!
The M735, developed in the 1970s, could penetrate 150mm of armor placed at the same angle at 2930 meters, which is equivalent to over 300mm!
The M900 in the 1990s could penetrate 540mm of armor at a distance of two kilometers.
Of course, in the hands of the Chinese, after some modifications, it had even more unlimited potential.
Now, this is just the beginning of this great journey.
Since Yang Zhenhua didn't mention it, Qin Yang wouldn't either.
After all, the fates of prophets are not good; the unlucky ones are even tied to pillars and burned to death.
"Leader Yang, the tank testing team is calling you over," just then, a soldier ran over to report.
"Okay, I'll go right away.
Engineer Qin, you guys continue testing."
Yang Zhenhua took a motorcycle with a sidecar inside the base and arrived at the tank testing range.
At this time, a large group of technicians were circling around the tank.
Zhao Mancang, an engineer from the 617 Factory, jumped down from the tank, sweating profusely, and said to the people in the tank's shadow below: "Mr. Smith, we have adjusted it repeatedly, but we still can't hit the target at a distance of 1000 meters.
What exactly is going on?"
This Type 69-3 tank not only replaced the L7 tank gun but also used Marconi's TSFCS simple fire control system with a digital ballistic computer.
The system response time is no more than 10 seconds.
According to the manufacturer, this fire control system has a first-round hit probability of over 80% at a distance of 1000 meters.
But now, in their tests, they haven't hit it once!
Almost every time, they miss the target!
"For a cannon to accurately hit a target, it's not just a matter of the fire control system and the accuracy of the tank gun; it also has a lot to do with the tank chassis," Smith, a technical expert from the British Royal Ordnance Factory, said calmly after hearing the translated words: "I'm not very clear about the specific reason.
If you want to determine it, it's best to transport this tank to our place for us to debug."
Zhao Mancang frowned.
They had been at the state firing range for several months, constantly carrying out modification tests.
Who would have thought that they would miss every time!
In fact, it's not easy for domestic tanks to hit a target within 500 meters, but the tank gun with the patent introduced with a large amount of national funding must be able to exert its full strength!
It can hit targets 1000 meters away when installed on European tanks, so why doesn't it work here?
They had carried out continuous debugging for three days this time, and only today did they re-fire the gun, but they didn't expect to miss the target again.
"How is it?
How's the accuracy?" At this time, Yang Zhenhua walked up and asked everyone.
No one answered; you could tell from everyone's discouraged expressions.
"We haven't conducted moving-to-stationary shooting yet; we're just using short stops to shoot, but we're still missing the target," Zhao Mancang finally opened his mouth: "The British experts' suggestion is to send the tank to them for debugging."
Send it to the British?
How much would that cost?
Yang Zhenhua frowned, and moreover, if it was sent over, what secrets would the tank still have?
"We've thought of all the possible reasons during this time, but it still doesn't work, alas!" Zhao Mancang sighed.
"How about I find someone to help take a look?" Yang Zhenhua thought of something and suggested.
"Find who?"
"Engineer Qin from Factory 960."
