After taking control of Luohai City, Lin Ziran got the three major arsenals of Fuyuan Ordnance Factory, Nanzhou Machinery Bureau, and Luohai Shipyard, not to mention Luohai Shipyard.

Let's say that the Fuyuan Ordnance Factory and the Nanzhou Machinery Bureau, their huge production capacity is enough to arm millions of troops, and now it is more than enough to arm the approximately 150,000 troops under Lin Ziran's command.

Fuyuan Ordnance Factory produces breech-loading rifled rifles and matching all-metal bullets, and also supplies other ordnance products, such as sapper shovels, command knives, cavalry knives, water bottles and other materials.

The Nanzhou Machinery Bureau, on the other hand, can supply a large number of artillery.

As soon as they took control of the factory, the relevant officials of the Ordnance Department under Lin Ziran were already stationed in the factory, instructing the factory's technicians to adjust the production line in order to produce steel rifled artillery.

When they learned that the air leakage problem of the rear-loading artillery and the strength of the cannon bolt relied on the wedge bolt, and the solution to the problem of the shell fuse relied on the collision fuse, and at the same time used the cylindrical shell, so as to obtain greater explosive power, and at the same time stabilize the trajectory and let the shell rotate steadily, the expressions of all technical experts were in disbelief.

"It's that easy to fix the air leak problem?" One of the technicians was still incredulous: "Is this bolt strong enough?" ”

"We've tried using threaded bolts before, but the materials aren't up to par and we can't use them at all!"

The steel breech-loading rifled gun that Lin Ziran instructed Qingshan Machinery Factory to make is very simple on the surface, but it is actually a complete set of systems.

It was not enough to have a wedge bolt, it was also necessary to use it with a cylindrical shell with a collision fuse.

If these things are separated, they are actually not very difficult things, at least for the contemporary Blue Star and the contemporary Daheng, these are actually not insurmountable technical difficulties.

But no one had thought of this before, and no one had combined them.

But Lin Ziran asked people to come up with these things and combine them, so there was such a thing as a steel breech-loading rifled gun.

With the technical background and scale of the Nanzhou Machinery Bureau, after obtaining these related technologies, the production line was quickly adjusted, and it did not take long to produce this 75-mm prototype gun.

After the test launch, the officials of the Ordnance Department and the technical experts who came from the Luoan Arsenal to guide all had strange expressions.

Because of this sample gun from the Nanzhou Machinery Bureau, the results of the test firing exceeded their imagination.

Its effective firing range is several hundred meters greater than that of the Luoan Factory, and more importantly, when conducting rapid fire, this sample gun of the Nanzhou Machinery Bureau has withstood rapid fire for a longer time, which means that the barrel of their sample gun has a stronger bearing capacity.

During the test, an engineer in charge of the production of the sample gun from the Nanzhou Machinery Bureau was not polite at all: "In the process of manufacturing the sample gun, we found that the formula of the barrel material was a little problematic, and after discussing it with the engineers of the steel plant, we slightly improved the formula, and now the performance of the barrel material we use to withstand high temperature and high pressure is about 20 percent higher than that of the original material." ”

"Not only does it allow the gun to withstand more chamber pressure to increase the range and duration of rapid fire, but it also effectively reduces the likelihood of exploding!"

"In addition, we have also made some detailed adjustments to the gun mount to reduce the weight and make the gun more stable when firing to improve the shooting accuracy!"

"In addition, we also found that some details of the collision fuze of the shell have some problems, which are prone to duds, and our experts have also adjusted and improved this problem, and after our tests, the ignition rate of the improved collision fuze has increased by at least 30%!"

Listening to the introduction of the experts of the Nanzhou Machinery Bureau one after another, several officials in charge of artillery in the Ordnance Department were surprised at first, and then they were all ecstatic.

The problems they said naturally have existed for a long time, for example, the problem of duds, which has always been relatively serious, but since you know why not solve it, you don't have the technical ability!

Now the Nanzhou Machinery Bureau has just passed one side, and it has been solved immediately.

After the test, the Ordnance Department did not hesitate to directly place a large number of orders, and at the same time asked the Luoan Arsenal to produce follow-up guns according to the improved model.

Don't talk about other places, and say that after the Nanzhou Machinery Bureau got the official order from the military, it immediately began to organize production, and they reported that the production capacity of each month was estimated to be about 30 at the beginning, but it could be directly increased to 60 in the future.

This is only a 75-mm field gun, and at the same time, the Nanzhou Machinery Bureau will also simultaneously produce 150 mm short-barreled howitzers, which is not a small output, and it is expected to be able to produce more than 20 per month.

In addition, the Nanzhou Machinery Bureau also took over the research and development of 100 mm, 120 mm and other calibers, regardless of the barrel of the rear-loading artillery.

In just a few days, the formalized research and development projects include light 75-mm howitzers, 100-mm field guns, 120-mm field guns, 120-mm howitzers, 150-mm field cannons, and other army artillery of different calibers and different purposes.

In addition, according to the needs of the navy, they also simultaneously developed rear-loading rifled guns of different calibers for the navy, among which the 150 mm long-barreled naval gun and the 120-millimeter long-barreled naval gun are their key research and development projects.

Basically, rear-loading artillery projects of various calibers and various purposes, they have carried out relevant research.

And one of the most important research projects, if not others, is still a 75-mm field gun.

They intended to work on a 75-mm gun with a longer barrel and a longer range.

The army has not yet made a request, but they themselves have made a request for themselves, saying that they want to develop a 75-millimeter field artillery with an effective range of more than 6,000 meters and a weight control at the current level.

In this regard, even Lin Ziran heard of it, and felt that their stall was too big.

For this reason, I specially asked one or two, saying that your Nanzhou Machinery Bureau can't be leisurely, and it's useless for you to engage in so many artillery projects at once, so it is better to concentrate on producing more 75-mm field guns and 150-mm howitzers, and as for the research and development of new artillery, you can just do a few, and you don't need to launch a full fifteen projects for the army and navy at once.

As a result, the people of the Nanzhou Machinery Bureau were very aggrieved and said: We had more than 30 research and development projects of various artillery models before, and now we have turned to research and development of after-loading artillery, the original projects have been stopped, and the new after-loading artillery projects are only fifteen in total.

Hearing this, Lin Ziran didn't know what to say, forget it, what do they like!
