For the Shanghai Guns and Cannon Factory, the most important thing now is the 300 mm rear-loading gun, because only by creating this cannon first can we hope to get the order for the navy's huge rear-loading rifled guns with other calibers such as 250 mm, 200 mm, 150 mm, etc.

The navy has already issued a death order. The main gun of the new battleship must be a large caliber naval gun of 300 mm, not even a millimeter less!

Even the navy's internal government departments and the Shanghai Guns and Cannon Factory have reminded the navy that the 7,000-ton hull of the Guangdong hull was barely equipped with a 300-mm rear-mounted gun, and it was not equipped much, at most, at most two doors, and no matter how many, it would not be able to be installed.

Only the Luzon-level battleships under construction, such as the 10,000-ton, are more suitable for rear-loading guns equipped with 300 mm.

But the navy doesn't care!

What they want is a 300-mm giant cannon. No matter how many they install, they need a 300-mm rear cannon.

As for you talking to him about cost-effectiveness or actual combat effectiveness, the Navy will look at you with contempt!

Who told you that battleships are used for war?

In the eyes of many senior navy leaders, these battleships of 7,000 ton or even 10,000 tons are not used for wars at all. They only have one function, that is, to show off!

Showcase the prestige of the Tang Dynasty and highlight the naval momentum!

As for fighting with the enemy's navy, the Tang Navy had a large number of frigates and cruisers of one or two thousand tons, and even three or four thousand tons of Shanxi-class and Guangxi-class battleships.

Is it necessary to use giants like Guangdong and Luzon?

The navy has never considered actual combat performance at all, so it is firm and persistent to require the largest naval guns.

The largest caliber of the naval guns that can be produced by the Tang Empire are naturally 300 mm naval guns, whether they are equipped with rifled guns in front or rear.

In addition, the army has been fighting with the army in recent years, and the army has been waiting to see the navy's jokes.

Therefore, the 300 mm rear-mounted gun is not a matter of combat effectiveness and cost-effectiveness for the Navy, but a matter of face and reputation!

If the Shanghai Guns and Cannon Factory can handle this artillery.

The Navy was happy. Even the number of giant battleships was not too large, and each ship could not be equipped with a few giant cannons, so the Navy's general offensive could not purchase a few cannons.

But this is fine. The Navy never treats the manufacturers they value. There is no order for the rear-loading gun of 300 mm, but the Navy has a large number of other small and medium-caliber artillery orders.

On the contrary, if the Shanghai Guns and Cannon Factory can't handle it, the Navy will be unhappy and will not even give you the order for a small caliber naval gun. The Navy has already threatened it like this and has threatened it several times.

So if you want to compete for orders for rifled and rear-loading guns of other calibers in the Navy, you have to get the 300 mm rear-loading guns first, and then talk about it after giving the Navy a big face!

Otherwise, no talk!

In fact, the Navy also made the same promise to Foshan Guns and Cannon Factory and Tianjin Guns and Cannon Factory. They used other gun orders as bargaining chips and hung them in front of major manufacturers, making them desperately develop a 300-mm rear-loading gun!

After the Navy began to enter the rifled gun era three years ago, although it was still equipped with a large number of smoothbore guns, they were all old guns equipped on old ships. The newly built warships were basically all equipped with front-mounted rifled guns.

However, for the Navy, the front-mounted rifled gun is just a transition. What they want is to fully equip the rear-mounted rifled gun. However, domestic artillery manufacturers were not powerful enough before, and they could not find a useful rear-mounted rifled gun after tossing and troubling.

However, the Navy's intention to fully upgrade its replacement and then install cannons is something that all the people of the Tang Dynasty know.

And this means a huge market!

The largest market is not the top 300mm rear-mounted gun, but a large number of medium-caliber rear-mounted guns.

According to the new era artillery division formulated by the Navy three years ago, the previous classification methods based on the weight of the shell were cancelled, but the caliber size and length of the body tube were used as the classification methods.

At present, among the newly built warships of the Tang Dynasty Navy, medium-caliber naval guns are actually the largest demand.

Hundreds of tons of offshore patrol ships, 1,000-ton frigates, 2,000-ton cruisers and 4,000-ton battleships, the above-mentioned ships require a large number of medium-caliber naval guns of seventy-five millimeters, one hundred millimeters, one hundred twenty millimeters, one hundred fifty millimeters, and one hundred seventy millimeters. In addition, the number of ship guns of two hundred millimeters, two hundred and thirty millimeters and two hundred and fifty millimeters is not small.

Especially the 150 mm naval gun, whether it is the front-mounted rifled gun that is now equipped or the rear-mounted rifled gun that is intended to be equipped in the future, the demand is extremely huge.

Because this is the main gun of frigates and cruisers, and it is also the main sub gun of large-tonnage battleships, the number is very large.

Shanghai Guns and Cannon Factory was almost defeated in the era of pre-installed rifled guns, but in the era of future post-installed rifled guns, they wanted to win back a battle.

The stepping stone is a 300-mm rear-mounted rifled gun.

The manufacturing of sample guns is very fast, because in order to compete for time, the Shanghai Guns and Cannon Factory almost spared no expense and used a lot of manpower and material resources to make sample guns. At the same time, they have accumulated a lot of experience in the field of rear-loading guns.

Even if it is a failed experience, it is also an experience.

After their sample guns came out, Foshan Guns and Tianjin Guns Factory came to realize that Professor Wei Qingxin from the Royal Institute of Technology had already solved the gun bolt problem, so he hurried to the time when the Royal Institute of Technology was seeking patent authorization.

The people from the Shanghai Guns and Cannon Factory have invited the navy general to watch the live ammunition test of the sample cannon again.

In the test yard in the suburbs of Shanghai Guns Factory, Ji Haifan said with concern: "Mr. Luo, the test will be fine. I promised it on the Navy and said that this test will definitely be successful, and the Navy also requires a strong charging test!"

Luo Guangjian said: "Don't worry, we had already tested live yesterday. There was no problem with standard charges. There was also test shots for strong charges three times, but there was no problem!"

"It's good that there is no problem!" Although Ji Haifan said so, he was still a little worried.

As the deputy general manager of Jiangnan Weapons Company, he is mainly responsible for artillery business in Jiangnan Weapons Company. Shanghai Guns and Cannons Factory is the leading artillery factory in Jiangnan Weapons Company, and undertakes the research and development and production tasks of most medium and large-caliber artillery in Jiangnan Weapons Company.

If it weren't for the importance of Shanghai Guns and Cannon Factory, he wouldn't have run from Jinling City to Shanghai again and again.

The success of the factory is his political achievement, but if it fails, there is no doubt that he will be responsible.

Worried, he looked up at the giant cannon in front again. This was the 300 mm twenty-five-times rear-mounted rifled cannon just built by the Shanghai Guns and Cannon Factory.

This is a giant. Not to mention the artillery itself, even the shells fired have a weight of more than 300 kilograms.

Although its huge barrel is twenty-five times the caliber length, its huge gun body still makes the gun appear thicker and less slender than the small caliber long-body cannon.

Seeing such a large cannon, and having conducted five live-fire tests yesterday and all of them were successful, he felt a little relieved.

Everyone didn't wait long, and soon saw a team of four-wheeled carriages coming in outside, and the navy's observation team came.

The leader is not someone else, but Admiral Wang Haiqing, Minister of Navy Ship and Government, and the others are also senior naval generals.

Today, more than twenty generals who were brigadier generals or above came!

This shows the Navy's emphasis on this artillery!

However, the more the Navy attaches importance to it, the more worried Ji Haifan is. He had known that he would not have sweared to the Navy a few days ago that the artillery had been completely successful, so the Navy could rest assured.

At that time, he didn't leave any room for speaking, which made Ji Haifan extremely worried now.

Admiral Wang Haiqing came with his men. After both sides greeted him, they took the men directly to see the giant cannon in front of him.

At this time, as the designer of the gun, Luo Guangjian was naturally responsible for explaining the technical parameters personally, and many technical parameters were not important. The key point was that they used new gun bolts to completely solve the gun bolt problem.

As for other aspects, the technology is actually very mature. For example, the Shanghai Guns and Cannon Factory has been playing with cannons for so many years and has long overcome the technical difficulties of manufacturing large-caliber gun barrels. Let alone them, Foshan Guns and Cannon Factory and Tianjin Guns and Cannon Factory can also create such gun barrels of 300 mm and 25 times the caliber.

In today's test, the important thing is to test new gun bolts, not other things such as gun barrels.

Although Wang Haiqing is not a naval general who has a technical background, since he can be the Minister of the Ship and Government, he is naturally of course a bit skillful. Without Luo Guangjian's explanation, he can see the characteristics and advantages of this cannon from the technical information he obtained before.

Regarding this artillery, the performance instructions given by the Shanghai Guns and Cannon Factory are very clear. The cannon weighs about 35 tons. When it is fired at a thirteen-degree elevation angle, its maximum range can reach an astonishing eight thousand meters. When it is fired, its power is amazing.

Needless to say, the ability to use solid armor-piercing bullets to break armor is impossible to withstand, except for the thick armor on the Luzon battleship under construction, other warships in the Tang Dynasty Navy, including the Guangdong.

As for the wooden ships of other countries' navies, let alone, they can directly hit one by one!

If the grenade is launched, its explosion power is even greater.

Wang Haiqing had known how powerful the 300mm grenade is. In the past, the Tang Dynasty Navy also had several 300mm front-mounted or rear-mounted rifled guns. Although they had not been actually equipped, they were fired too much during the test.

Although the artillery is different, the shells are basically the same, they are all 300 mm cylindrical howitzer shells, and they also use the latest collision fuse produced by Xuzhou Precision Machinery Company.

As for how powerful is the 300 mm howitzer shell?

Luo Guangjian’s statement is very interesting:
