Lin Shenhe raised his telescope and looked at the floating boat in the distance. [No pop-up novel website] When the shooting angle is increased to 10 degrees, the splash point of the cannonball is not far from the furthest five-kilometer ranging ship. This still uses black powder. If a mixture of nitrocellulose and nitroglycerin can be used, the distance may be even greater.
"It's a pity that the fire control level is so poor." Li Yunxing sighed regretfully. Based on visual aiming and gun table calculations, if you hit a moving point target on the sea, a 5% hit rate at this distance is considered a good rp. The biggest contradiction encountered by the Weapons Research Institute in artillery is that the range of the artillery that can be manufactured greatly exceeds the fire control level.
"Add a scope to the cannon." Bai Yu said jokingly.
"I would like to, but there is no suitable mirror. It will be great when the industrial sector can produce optical glass and make direct sights."
"It has always been impossible in recent years. It is still useful to calculate, prepare a table of shot numbers and solve equations, and let the gunner memorize them."
"But this cannon is really powerful!" Wang Ruixiang affectionately caressed the polished green cast steel cannon, "It's quite thick!"
"The Planning Commission only allowed us to cast two such 15° cannons." Lin Shenhe felt somewhat regretful. "To defend the entire Bopu, two cannons are not enough. We have to cast more smoothbore cannons."
"I think it would be better to cast a few less cannons. Casting too many miscellaneous cannons is a waste. We can't just satisfy this elementary level." Bai Yu said. He had formally studied weapons making and lacked enthusiasm for these old-fashioned artillery pieces.
"You're right, but it's a pity that there are still too few cannons. Bo.pu needs to be turned into a fortress, and these few cannons are not enough." Ying Yu shook his head. As an artillery commander, he belongs to a cross-arms group. There are gunners from both the naval and military armies. Training is conducted in his artillery company, and he is responsible for the firepower arrangement of the fort in the Bopu fortification project. "With these two, there are only six cannons that can be installed in the fort area. What use are these?"
"It is not difficult to cast new cannons, but we should standardize the cannons. It is too random now and the standards are a bit confusing: there are standard calibers and standard bullet weights. It is too difficult to reserve ammunition." Li Yunxing suggested.
"Of course, all personnel must be equipped with rifled guns." Ying Yu looked down on smoothbore guns. "The Sixth Army can use imitation Japanese 92 infantry guns plus mortars. The Navy uses 7omm or 1oomm breech-loading rifled guns. "
Lin Shenhe found a clean stone and sat down: "According to our current industrial capabilities, let's do it step by step. For the artillery used by the new army, the Sixth Army will still use smoothbore cannons for the time being - the Sixth Army needs a lot of artillery. The frequency of use is high, our existing materials are poor, and the ammunition manufacturing capability is weak. Smoothbore cannons do not have high requirements for these things and are simple to manufacture. It will not hurt if they are lost. The divisions are based on traditional bullet weight. I think Four types of 6-pounder, 12-pounder cannon, 12-pounder mountain howitzer, and 24-pounder howitzer are enough.”
"Don't you need a mortar?"
"That's pretty much what the 24-pound howitzer means." Lin Shenhe said, "As for the cannon used in siege, it is a special type and is not included in the regular equipment."
Wang Ruixiang thought of the killer weapon of the infantry: "When talking about mortars, I thought of using mortars."
Lin Shenhe said: "The technology is not difficult. The main problem is the ammunition - the fuze. If you don't have a good fuze, don't do this."
Lin Shenhe continued, "As for the navy, breech-mounted rifled guns, or at least rifled guns, are a trend - the number of warships that the industrial sector can provide is small, and it is not easy to train qualified sailors. Ships and people are valuable, so try to use them as much as possible A rifled gun with long range and great damage can at least protect itself when encountering a strong enemy."
"I agree with this. Equipment still depends on our industrial capabilities and the level of the enemy. There is no need to buy too much. If you buy too much, it will take up more resources and have an impact on industrial upgrading." Li Yunxing said.
"Let's go back to the headquarters."
Everyone got off the gun emplacement and returned to the fortress headquarters. The newly completed fortress headquarters was located on the top of Pujiao Beacon Tower, in the same place as the heavy artillery emplacement. This artificial hill with a height of more than 25 meters and a slope of 45 degrees was transformed into the main support point of the entire thin-paved fortress area. In addition to the original lookout posts and searchlights, the fortress headquarters, soldier dormitories, and ammunition were also added to it. library and many other buildings.
In order to transport numerous building materials and heavy cannons to the beacon tower, the construction company dug a winch slideway on the hillside and used an electric winch to pull the cargo bucket to the top of the beacon tower, which completely solved the transportation problem. In the end, the winch was expanded into a covered and hidden tunnel. In addition to transporting people and materials, telephone lines and power lines that were originally easily damaged in a day were also moved to the inside of the tunnel.
Barbed wire was erected around the top platform and trenches were dug. The Navy has a marine platoon stationed here. Includes one gunner squad and two infantry squads.
The Bopu camp at the foot of the beacon tower has been strengthened accordingly, including upgrading all the original simple wooden structure lookout towers into masonry structure turrets. The mechanical department cast a batch of 12-pound howitzers in batches for these turrets. They were installed on old-fashioned naval gun mounts, using pulleys to buffer the recoil. The shells fired are mainly shotgun shells, which are mainly used as machine guns.
Next to the trestle leading to Fengcheng Lun, a four-story fort with a masonry and cement structure was built. A 32-pound cannon and a 12-pound mountain howitzer were installed on the fort. A platoon is usually stationed on the fort.
Finally, there is the Fengcheng Wheel itself. Its tall body can also play a role similar to the Bobu beacon in the port. The ship itself has multiple sets of searchlights. Very useful as a turret. Moreover, the Fengcheng Wheel itself is extremely valuable, and adding artillery to it is a double-edged sword. Another 15mm cannon was installed on the front deck of the Fengcheng ship - they all used the anti-recoil device recently developed by Lin Shenhe, and the artillery can be maneuvered manually.
In order to strengthen the protection of Fengcheng itself, the Executive Committee issued a special "Fengcheng Management Regulations". All unused cabins must be locked, and all portholes must be closed and locked except those that need to be opened regularly for ventilation. All movable tools, furniture, accessories and other items on board must be registered and must not be used at will. The boat ramp must be retracted before dark each day.
In addition to these supporting points, a fort and navigation light were built on the high corner - a fort was built here during the Westernization Movement of the Qing Dynasty.
"You can also create a batch of mines to block all blind spots. Basically, the port area is impregnable." Li Yunxing said: "For safety reasons, it is best to use visual electric mines."
"Wires, wires." Lin Shenhe said, "Wires are first-class materials. If you use them to make mines, the Governor will eat you alive."
"No way, haven't the wires been trial-produced a long time ago?" Li Yunxing had already seen this news from the internal communication of the Work Energy Commission at Lingao Telecom.
"Are you safe if the enameled wire is soaked in sea water?"
"Enameled wire?" Li Yunxing was disappointed. But then I thought about it and it was right. The insulating materials for modern telecommunications are either plastic or rubber. Neither of these two things exist here and now, nor can humans create them out of thin air.
Lin Shenhe said: "It should be possible to build a fixed anchor mine."
The anchor mine itself does not have much technical content, judging from the level of the time travel industry: the mine body is made by casting method, and black powder is used for loading - the explosive power of 3og of black powder is enough to destroy any ship in this time and space. A certain gap is left in the mine body as a buoyancy reserve. The anchor chain used to moor the mine body can be made of iron. If this is not possible, it can be fixed to the seabed with a strong cable and an iron anchor.
The slightly more difficult thing is the fuze. In order to ensure that the impact is effective, multiple fuses need to be installed on the anchor mine, which should be cheap and easy to obtain, and the fire must be reliable. The people in the weapons team decided to start working on the manufacture of anchor mines after finishing the artillery manufacturing work.
"To be honest, if the situation is not critical, it would be better not to deploy anchor mines. There will be endless troubles." Chen Haiyang, who was looking at the deployment map with them in the headquarters, said, "This thing will go missing after it is deployed. There is no place to look for it, and it is troublesome and laborious to clean it up, and the effect is not good.”
He sighed: "It just so happens that this mine is very durable. Even a mine ship from fifty or sixty years ago can be exploded if it hits it. Mines are still being cleared in the Yangtze Estuary channel - the remaining mines laid by gd during the Anti-Japanese War are still there. "
"I guarantee that the mines we make will never last for fifty or sixty years, and will definitely fail in a few years at most." Lin Shenhe said jokingly.
While discussing the fortification plan and only listening to the sentry report, Li Haiping arrived.
Chen Haiyang looked at the application sent by Li Haiping and frowned. Although it was almost certain that the Executive Committee would interview Li Huamei, he was unable to reply to the wishes made by the following grassroots officers.
"Guns must not be given," Chen Haiyang said. "Don't say I don't have the power. The executive committee has to discuss the issue of giving firearms to the indigenous people. Your wish is out of scope."
Li Haiping said anxiously: "When people train us sailors, they must give us benefits."
"There are many benefits, why do you have to make up your mind on guns?" Chen Haiyang said, "I can't make the decision on this matter. I will report it to you during the meeting. How to decide depends on the executive committee."
"Isn't this too bureaucratic? We are in urgent need of friends now! We can always visit the Fengcheng Ship, right? Instead of entering the cabin, just walk around on the deck."
"Whether we are friends or not is not something that our Navy has to deal with. Also, if you apply to take her to visit the Fengcheng Ship, this matter must be approved by the Executive Committee."
"What is this-"
At this time, the phone rang. Chen Haiyang picked up the phone, said "yes" several times, and then said Li Haiping's application again:
"Yes, that Li Huamei's attitude seems to have changed, so - eh? Yes, yes, okay. I understand!" He hung up the phone and said to Li Haiping:
"You're lucky. The executive committee agrees that you take her on board the ship for a visit, but you can't enter the cabin! The executive committee has a task that requires her cooperation."! ~!
