Open an aircraft carrier to fight against Japan

The officer said again: "Is that Luo Rongguang too arrogant, do you want my subordinates to teach him a lesson for you!"

Lin Yuan shook his head quickly, and said, "I'm fine." Everyone then walked up the hillside, which was a low mountain, and soon reached the top of the mountain. Luo Rongguang pointed to the surrounding mountains and said: " Commander Lin, look, there are forts on these mountains, forming a criss-cross pattern, which can form crossfire against the enemy. This fort is located on the top of the mountain, so it will not be bombed by the shells that fall after the enemy hits the mountain."

Luo Rongguang led Lin Yuan into the artillery position again, and Luo Rongguang said as soon as he entered: "The cannon here is an underground cannon. It can be lowered below the launch port when it is not fired, and it can be raised again when it is fired. And a cannonball After firing, it will fall down again, and after loading, it can be raised and fired again, avoiding the danger of being hit by enemy artillery.”

Lin Yuan asked, "Then where are your shells and propellants?"

Luo Rongguang said: "There is a cellar under the fort, where the shells and propellants are placed. Our soldiers have undergone strict training, and the speed of transporting shells is very fast. Please let me demonstrate to Commander Lin."

After Luo Rongguang finished speaking, he said to the soldiers in the fort: "Load the shells!"

The soldiers moved when they heard the sound, and one soldier quickly opened the door of the cellar, only to see a slope below the cellar, two soldiers rushed into the cellar as fast as monkeys, followed by four soldiers, two by two, separated by two Mi stood, and the two soldiers in front raised the shells and handed them to the soldiers behind. Several people handed over the shells to the gunners, and the two gunners gently placed the shells in front of Lin Yuan.

Lin Yuan nodded lightly, thinking: "The delivery speed of this shell is fast enough!" At this moment, the soldiers handed over another propellant package, and put the propellant package next to the shell.

Lin Yuan squatted down, looked at the shells, opened the propellant bag again, picked up a little propellant with his hand, looked at it in his hand, then clapped his hands and stood up, saying: "Very good, let's see here first today, Mr. Luo, your troops are very good, they can be called elite!"

Luo Rongguang was praised by Lin Yuan, his face was bright, and he was very happy. Lin Yuan said again: "I want to read some materials, and I hope I can go to your headquarters." After finishing speaking, Lin Yuan turned around , Said to the accompanying military officer: "You don't have to follow."

Luo Rongguang then brought Lin Yuan to the headquarters. Lin Yuan read all kinds of materials before leaving.

As soon as Lin Yuan came out of the barracks, he went directly to the Tianjin Machinery Bureau. As soon as he entered the door, he asked, "Is Mr. Luo there?"

The person inside said, "It's on the shooting range."

Then Lin Yuan came to the shooting range and saw a group of people setting up targets from a distance. Unlike usual targets, the targets set up this time were not arranged in a row, which seemed irregular. Luo Chaoying stood aside and directed: : "Xiao Liu, go a little further back, Xiao Wang, go a little further forward..."

Lin Yuan came over and asked, "Old Luo, what are you busy with?"

Luo Chaoying smiled and said, "Of course I set up a target." Lin Yuan quickly asked, "But your target looks messy."

Luo Chaoying said: "At this time, when testing the lethality of shells, the fan-shaped targets are commonly used. The explosion point is the center of the circle. The targets are located on different radii, so that the lethality of shells at different distances can be analyzed with fewer targets."

Lin Yuan nodded and asked, "How long will it take to complete the erection?"

Luo Chaoying said: "It will be almost ten minutes, what, do you have something to do?"

Lin Yuan said: "Today I went to see the Dagukou Fortress in Tianjin."

Luo Chaoying asked, "Where are you going and what are you doing?"

Lin Yuan said: "The Russian fleet is coming, I'll go and see the defense situation there." Luo Chaoying said: "I heard that this Luo Rongguang is a strong general, he manages the army well, and the fort defenders are elite. "

Lin Yuan said helplessly: "Alas, this Dagukou Fortress looks like a rock, but it is actually vulnerable to a single blow."

Luo Chaoying was taken aback when she heard this, and asked, "What's going on?"

Lin Yuan said: "If they are impenetrable, I won't have to come to you. I can't explain a sentence or two. Let's go to the room and explain in detail."

Luo Chaoying quickly directed everyone to set up the target, followed Lin Yuan to the room, and as soon as he entered the room, Luo Chaoying asked, "Is their defense level that bad?"

Lin Yuan said: "Their soldiers are indeed good, with strict military discipline and a strong style of work, but their training is problematic. When I went, I saw that they were measuring the distance and azimuth, manipulating the artillery to aim, but I didn't know how they calculated it. The enemy's ship is fast, and I didn't see a timing tool in the house."

Luo Chaoying said: "Maybe they have it, but they didn't take it out."

Lin Yuan said: "I hope so, but the root of their problem lies in the design of the fort." As he spoke, Lin Yuan took out a layout plan of the artillery emplacement from his pocket and spread it on the table.

Lin Yuan pointed to the layout plan and said: "The distance setting of these gun positions is not very reasonable. The rear gun positions are too far from the front ones. When the enemy ships come, they will definitely attack one by one. There are dozens of doors, but only the front ones are used to meet the enemy."

"And I also looked at the information of their artillery in detail, combined with the height of their artillery installation, I found that the adjustable pitch angle of their artillery is relatively small, which caused the artillery at a high place to hit the enemy ships nearby. , the low-level artillery can’t hit the enemy ships in the distance, which is an embarrassing situation, so they have very few artillery that can attack the enemy at the same time, and the enemy can easily form a force advantage.”

Luo Chaoying nodded and said, "Their artillery calibers are large, and these heavy artillery can also cause great damage to enemy ships."

Lin Yuan said: "I looked at the propellant carefully, and found that the propellant is the maroon propellant produced by Tianjin Machinery Bureau. The shape of this propellant is solid. The shape of the propellant has a great influence on the burning speed. The faster the burning speed The faster the shell, the longer the range, I believe you know this better than me."

Luo Chaoying nodded and said: "Of course, this kind of gunpowder also has the problem of insufficient combustion, that is, there will be gunpowder residue, so they have to clean the barrel after firing a certain number of shells, so that the rate of fire will be slow."

Lin Yuan said: "In this way, their rate of fire will not be fast, and the power of their shells is not optimistic!"

Luo Chaoying said: "The power of the shell mainly depends on the amount of charge and the type of explosive. I have heard that their shells are made of solidified nitroglycerin as explosives. The explosive power is still very strong."

Lin Yuan said: "I have carefully read their purchase list. They did buy some shells when they bought the artillery, but these shells were no longer used because they were stored for a long time, so they used imitations from the Tianjin Machinery Bureau. The Tianjin Machinery Bureau does not have the strength to manufacture nitroglycerin, so it has to use black powder, and the explosive power is naturally inferior."

Lin Yuan said again: "I also heard that the armor on the Russian warships has adopted the latest heat treatment process, which is relatively hard and the shell fragments are less likely to penetrate." Luo Chaoying asked: "Then do we have any solutions? Make a new batch of shells for them?"

Lin Yuan said helplessly: "That's just changing the soup but not the medicine. What we need to do is some radical changes."
