Each galleon had two gun decks, with heavier six-inch guns mounted on the lower deck, also for the sake of the ship's center of gravity and stability.

Five-inch guns were mounted on the upper deck, and there was one five-inch gun in the bow and one in the stern.

On each side there were five five-inch guns and five six-inch guns.

All guns are front-loading smoothbore guns, and their maximum range is quite impressive.

When the firing angle is eight degrees, the firing range of a five-inch gun can reach 800 zhang, and even if the firing angle is only four degrees, the firing range can easily reach 500 zhang. Because the six-inch gun has more charge, the firing range is dozens of kilometers away.

Of course, at the time of the actual naval battle, because of the influence of wind and waves, the influence of non-stop movement on both sides, as well as the accuracy and airtightness of round shells and front-loading smoothbore guns, etc., the hit rate of long-distance battles was extremely low.

Therefore, the artillery battle between the sailing ships is generally close to 100 zhang, or even within 50 zhang, and the maximum horizontal shooting is used to complete.

Even so, the guns were unmatched against other ships of the era, and the decks and sides of the ships could be easily penetrated.

And the galleon itself strengthened its defenses in the waterline section, even with steel plates sandwiched between the planks, and the horizontal upper deck strengthened the defenses.

And the army models of these guns are also being improved, after all, the sea is different from the land, and such a heavy artillery plus a gun carriage with the same weight is not light, and it is simply impossible to maneuver on land.

Five of the first galleons were built, and they were the first members of the Han Central Navy.

Both the captain and the sailor underwent special training at the naval school to get used to the operation of the new ship, especially the tedious handling of the sails, as well as the use of artillery.

Just preparing the hundreds of guns on these five galleons cost a lot of manpower and material resources of the Jimo Military Industrial Base, and the cast iron refined was used in the artillery.

A lot of manpower was also taken, and the production of flintlock pistols was affected.

Fortunately, in the production of artillery and artillery shells, a lot of work has been replaced by machinery, which has accelerated production speed and improved efficiency and product quality.

For example, like grinding the gun chamber, the machine is much smoother and smoother than the manual one.

Escorted by five galleons, Lu Bu successfully arrived at the Jiaozhou Bay Naval Base, and along the way, it can be seen that various constructions are still going on on both sides of Jiaozhou Bay.

Lü Bu asked Xu Sheng, the chief of the navy who had already come up to the building to meet him, and Xu Sheng told him that the two sides of Jiaozhou Bay under construction he saw were mainly the infrastructure of the planned forts.

However, the large-caliber artillery has not yet been successfully trial-produced, and now a large counterweight stone thrower and six-inch artillery are temporarily installed to hold the sea.

This latest counterweight stone thrower can throw a 100-kilogram stone projectile at a distance of 600 zhang, which is almost the same as the maximum range of a six-inch gun.

The manufacture of the trebuchet is not as complicated as the artillery, so it can be mass-produced, and now the coastal batteries are temporarily filled with the trebuchet, and the artillery must be replaced in the future.

The two most important forts are the Tuandao Fort in the north and the Jiulongshan Fort in the south, which just hold the entrance and exit of Jiaozhou Bay.

In addition, defense facilities are also being built on Taiping Mountain, the commanding heights near Jiaozhou Bay, and forts will be built in the future.

Lu Bu nodded, it seemed that they had learned a lot of the lessons they had taught them in the military academy about the defense of the fortress.

When you enter Jiaozhou Bay, you can see the newly repaired wharf and trestle bridge on the shore, and some warships that did not sail before.

Xu Sheng told him that in the depths of the bay was the Jiaozhou Bay Shipyard, after all, a large dock had been built, and the galleon was built in the dock.

They are improving the drawings and preparing to build two types of sailing ships, larger and smaller, small ones that can be used for reconnaissance and communications, and galleons that can be equipped with more artillery and carry more people and supplies.

Lu Bu didn't care about resting, but he was full of curiosity about the new type of galleon, and after docking, he asked to change to a galleon and go to sea to inspect it.

Xu Sheng had to stop him, saying that they had also prepared the founding ceremony of the Central Navy for Lu Bu to attend, and whether the transfer to the galleon could be carried out after the ceremony.

Lu Bu slapped his forehead, but didn't he come to Jiaozhou Bay for the founding ceremony of the Central Navy?

This made the galleon and the artillery excited, and forgot about it, he nodded, then hurry up and start!

In fact, the army building ceremony is also very simple, that is, to ask Lu Bu to say a few words, issue the military flag of the Central Navy, and make simple personnel appointments.

Lu Bu still sighed, once upon a time, the Central Army did not even have a small boat, and after all these years of development, it was already possible to establish a navy.

What is called the navy is the army that goes to the sea and goes into the sea.

Lu Bu told all the officers and men of the navy that this world is very big, not only the Han Dynasty, but also not only these barbarians in the south, east and west, but also on the other side of the sea, there are more continents, mountains and rivers, and more countries and nations.

China has ships before, but it has never been out to sea, and there is a broader unknown world waiting for the warriors of the navy to explore!

All the naval officers, they don't ask Lu Bu why he knows so much, their own lord is such a person, a person who knows everything.

They had seen the sophistication of their ships and the sharpness of their artillery, and they did not think that there were any other rivals in the world that would prevent them from expanding their territory for the Great Han.

Soochow's navy? In their eyes, it has become a yellow flower of the past, a local chicken and a dog.

Maybe in the distance that Lu Bu described, maybe there was an opponent who could match them, right?

The Central Navy was divided into several sub-fleets, such as the Yellow River Fleet, the Yangtze River Fleet, of course, the Yangtze River Fleet had not yet been built, and the Bohai Fleet and the Yellow Sea Fleet.

After the army building ceremony was over, Lu Bu couldn't wait to take Zhuge Liang and others to the flagship of the Yellow Sea Fleet, "Chang'an", and the captain was Gan Ning, who was also the commander of the Yellow Sea Fleet.

Lu Bu was fresh and curious about everything on the galleon, after all, he didn't have the opportunity to board the sailboat in his previous life, and it was all missile warships at that time.

He raved about everything on the sailboat, and he couldn't help but get excited as he caressed the cold cannon and imagined it tearing apart his opponents.

The five galleons went to sea together, performed a maneuver off the coast of Jiaozhou Bay, and carried out artillery target shooting.

Zhuge Liang and the others watched the artillery firing at close range for the first time, and the deafening sound of the cannon and the huge power after hitting the target made them speechless!

You must know that they have seen dozens or hundreds of mortars attacking the enemy, and thousands of flintlock muskets firing in volleys, but now compared to this artillery, it is simply not worth mentioning.
