A few days after returning to Datong, Zhang Yunfei still worked at the command center as usual. Now, Datong's industrialization construction is in full swing, and several factories are starting to build at the same time. Zhang Yunfei is also busy with official business. Zhang Yunfei must grasp the general direction for many things. After all, Zhang Yunfei has more experience and his vision is very accessible to everyone.

Just as Zhang Yunfei was at the command center and was thinking about the next development plan of the base, the political commissar Fang Zheng suddenly walked in with a spring breeze and said to Zhang Yunfei with a smile: "Teacher Commander, the first twenty cannons from the heavy artillery factory have been offline." The latest updates are all available in the search.

"Oh, so soon, let's go and have a look together." Zhang Yunfei also said happily.

After returning from Yan'an, the first thing Zhang Yunfei did was to go to various factories to understand the progress of construction, and the construction of various factories was extremely smooth.

Under the guidance of so many technicians and experts, and under the free labor of thousands of Japanese Japanese, the construction of various factories is very fast.

Oil exploration has been completed. According to a report by Jewish expert Visel, the oil stock in Shiwan Village exceeds three million tons and is currently being exploited. A few days ago, crude oil was produced from the first oil well. The oil refinery in the southern suburbs of Datong is also speeding up construction.

The construction of the factory building, equipment and production lines of the automobile factory have also been completed. It is estimated that the first car that it produces itself will be offline in two or three months.

The construction of the armored vehicle factory has also been completed and production equipment is being installed. The first batch of armored vehicles and tanks will definitely be produced this year.

As for the aircraft factory, the construction of the airport and factory building has just been completed, and some production equipment is still being manufactured, but the design of the aircraft has been carried out in advance.

The heavy artillery factory that Zhang Yunfei was looking forward to was the fastest progress. When Zhang Yunfei first returned from Yan'an, when he visited the heavy artillery factory, the first batch of twenty 155 mm heavy artillery was almost completed.

Unexpectedly, less than a week after returning from the heavy artillery factory, the first batch of twenty heavy artillery was manufactured and taken off the line.

Zhang Yunfei and political commissar Fang Zheng boarded two jeeps and rushed to the heavy artillery factory in Huanglongxia Industrial Zone.

Now, the four-lane cement road from Datong to Xinan County has been almost completed with the construction of thousands of Japanese devils for nearly two months. Almost half of the road from Datong to Xinan County has been paved with cement, and the other half has also built the roadbed and is paving cement.

After more than two hours, Zhang Yunfei finally arrived at the Huanglongxia Industrial Zone. Currently, there are two major factories in the Huanglongxia Industrial Zone, namely the Huanglongxia Arsenal and the Heavy Artillery Factory. The Arsenal mainly produces guns, ammunition and small-caliber artillery, and the Heavy Artillery Factory mainly produces heavy artillery of more than 100 mm.

When Zhang Yunfei reached the heavy artillery factory, twenty black 155 mm howitzers were neatly placed on the open space in front of the heavy artillery factory.

Twenty heavy artillery pieces lined up, and the cannons were even wrapped with red silk ribbons. The artillery brigade commander Wang Daquan had arrived and was looking around the cannon and touching the cannon with his left and right. He looked like he couldn't let go.

Seeing Zhang Yunfei coming, Wang Daquan ran to Zhang Yunfei excitedly and said, "Teacher Commander, our artillery brigade has really replaced the cannons with a bird gun this time. Tsk tsk, I will also have a few cannons to get excited by this time."

"I want to be satisfied, right? I will let you fight a few shots later and be satisfied." Zhang Yunfei also said with a smile on his face.

Just when Zhang Yunfei and Wang Daquan were having a happy chat, Thoms, a Jewish expert in the design and manufacturing of these cannons, also walked to Zhang Yunfei with a happy face and introduced the performance of these cannons in detail to Zhang Yunfei.

This batch of cannons has a caliber of 155 mm, which is a howitzer. It has an average rate of fire of two rounds per minute and a range of 20 kilometers. The cannon weighs 4.5 tons. It requires cars to be towed forward. The maximum speed of road marching is 60 kilometers, and the maximum speed of off-road marching is 40 kilometers.

After hearing Toms' introduction, Zhang Yunfei nodded with satisfaction. This batch of cannons had basically met the requirements he had made.

However, the specific performance and quality are still tested.

Zhang Yunfei told the artillery brigade commander Wang Daquan: "Arrang to the truck to pull the cannons immediately, go to your artillery training base for a test fire."

"Okay, I'll arrange it right away and go to the training base immediately to conduct a test firing of the cannon." Artillery brigade commander Wang Daquan said excitedly.

Zhang Yunfei and political commissar Fang Zheng first took a jeep to the artillery brigade's training base, while Wang Daquan arranged for the truck to pull the twenty howitzers and followed it to the training base.

afternoon

At the training base of the Artillery Brigade, twenty cannons have adjusted their firing parameters. The black hole muzzle pointed to the distance. More than a dozen soldiers next to each cannon are ready. They can conduct live-fire tests after just one order.

On a hill more than ten kilometers away, there are dozens of man-made mounds of earth several meters high, each mound with a red flag, which will be used as targets for shelling.

Apart more than ten kilometers apart, these cannons, to see whether they can hit the target, will be one of the important criteria for testing the performance and quality of these cannons.

Seeing that they were ready, Zhang Yunfei asked the flag-speaking soldiers beside him to shoot flag-speaking soldiers that could be bombarded. Zhang Yunfei's observation point was nearly one kilometer away from the artillery position. At such a long distance, he could only communicate with each other through the flag-speaking soldiers.

Seeing Zhang Yunfei ordering the firing, several ammunition fillers held the shells weighing nearly 100 kilograms, quickly loaded them into the barrel chamber, locked the gun door, and then trotted a few steps away from the cannon a few meters away, and covered their ears.

Seeing that the main gunner had finished loading, he decisively pulled the line and rang the cannon. The cannon made a dull loud noise. The heavy barrels retreated several meters under the huge recoil force, but the cannon seats remained firmly, and the thick shells flew towards the target target more than ten kilometers away.

Zhang Yunfei even saw the beautiful trajectory of the shell through the telescope. After the shell flew in the air for twenty or thirty seconds, it accurately hit a target more than ten kilometers away and exploded a huge deep pit with a diameter of dozens of meters.

Seeing the cannon's power so powerful, the artillery brigade commander Wang Daquan was shocked. The cannon was too powerful. If this cannon went down, it would be wiped out and everything would blow into pieces.

Zhang Yunfei, who was watching the battle through a telescope, nodded with satisfaction. The power of the cannon was within Zhang Yunfei's expectations. Zhang Yunfei, who was used to the power of the giant cannons in later generations, was already unaccustomed to it.

Zhang Yunfei knew that a 155-mm grenade exploded with great power. Not only would a large pit with a diameter of dozens of meters would be blown out on the ground, but it would not be possible for anyone to survive within a radius of 100 meters. They would either be broken or killed by the huge shock wave.

The twenty cannons fired in turn, showing great power, which made all the officers and soldiers of the artillery brigade ecstatic. Compared with the previous Type 920 infantry cannons, it was a world of difference, and the difference was too big.

Finally, he had his own heavy artillery. As the saying goes, when the cannon fired, there were tens of thousands of taels of gold. Zhang Yunfei was very excited about the power of the cannon on the battlefield.

Wiesel, a Jewish expert who watched the live-fire experiment, looked happy when he saw the excellent performance of the cannons and took the opportunity to tell Zhang Yunfei that the second batch of twenty cannons will be produced at the end of this month. From now on, every month, the heavy artillery factory will produce thirty to fifty cannons.
