Liu Juntao stayed in Jinan for a whole month, during which Tang Yu, Minister of Commerce, mobilized a large amount of funds, a total of five batches, more than 7 million taels of silver, which were successively sent to Shandong Town.

With this money, Liu Juntao waved his hand and ordered the three shipyards in Rizhao County to work at full speed and prepare for a big fight.

After a month of screening and refinement, Liu Juntao's more than 20 drawings sent to the three shipyards have all been completed, and they have also been confirmed by the Dongping Island Navy.

However, there is one problem, that is, at this time, the warships of the Ming Dynasty are all hard-sailed warships, and it is not possible to complete it in a short period of time if the navy wants to re-adapt to the operation of the soft rice warship.

This point was really negligent on the part of Liu Juntao, so Liu Juntao urgently ordered to change all the soft sail designs in the drawings to hard sails.

Although this will make the ship less maneuverable, it is also a helpless move.

At this time, Liu Juntao did not stay in Jinan Fucheng, but set off for Andongwei, which had been expanded into a large "base" in Shandong Town, which was specially used to serve the Dongping Island Navy.

Today's Anton Weizhong, there are not only all kinds of shops, craftsmen repairing sea ships, but also various workshops, which is completely an enlarged version of the Yushan Town Military Bureau.

When Liu Juntao arrived here, Feng Xiang, the naval commander of Dongping Island, greeted him outside the door with a group of naval generals.

After everyone met, Feng Xiang and others pleaded guilty to Liu Juntao, but Liu Juntao did not blame at all, but comforted everyone.

After everyone entered Andongwei, Liu Juntao asked about the construction of the new warship.

At this time, most of the Western warships still had only one mast and one sail, which was no different from the early Nordic ships.

Most of these Western warships were built with shipyards, which were superstructures that stood above the bow (bow) or stern (stern) of the ship, which, like real castle towers, could be used as a commanding height for attack or defense in naval battles. This is similar to the building ship in China.

The huge mainsail rests on a horizontal boom, which can be raised and lowered up and down, or can be controlled by a swivel to rotate around the mast, which is connected to the boom by a folded ring at the end of the boom.

According to the drawings sent by Liu Juntao and their own experience, the three shipyards in Rizhao County added a second mast on the basis of the main battleship on the drawings, and installed a triangular sail, called a mast sail.

This new sail outfit aided in manoeuvring and made it easier for the ship to sail against the wind, which compensated for some of the maneuverability lost by keeping the ship stiff.

At the same time, another improvement of the shipyard's craftsmen was the stern rudder.

Previously, the rudder rows suspended on both sides of the stern were used to handle the boat, which were now replaced by monolithic rudders attached to the rudder posts.

The rudder was initially controlled by a lever, and as the ship grew in size, the helmsman had to stay below deck and listen to the loud shouts from above to steer the steer. Still, driving a sailboat is like playing a symphony, with the helmsman and sail crew working together until (and on) the last sailboat.

Liu Juntao knew that at this time, Western naval tactics had gradually developed from broadside battles and boarding ships to long-distance artillery battles, and at this time, Western warships had begun to try to line up in a linear line and concentrate their artillery to exert their power in order to inflict heavy damage on their opponents.

This requires the Navy's warships to have stronger hulls, more powerful guns, and more stable carriers.

Therefore, in the next ten days, Liu Juntao led Feng Xiang and other admirals of Dongping Island to study the classification of the warships used by the Dongping Island Navy on the basis of the finalized drawings of naval warships sent by three shipyards in Rizhao County.

At this time, the three shipyards in Rizhao County were already able to build several layers of warships, and this technology had actually developed and matured when Zheng He went to the West.

Therefore, Liu Juntao and others stipulated that the warships were clearly divided into six classes according to tonnage and purpose, which were from one to six.

First-class battleships must have more than ninety guns and three gun decks, and this kind of sea "monster" will not build too much, after all, the manpower, material resources, and sailors required on the ship are very large, so they are generally used as the flagship of the main fleet of the navy;

Liu Juntao named this class of warships Huaxia class, and named the ships after the sages of the Chinese dynasties, such as the Yellow Emperor, the Yan Emperor, and Chiyou.

Ships of the second class must have between sixty and eighty guns, three gun decks, and serve as the absolute main battleship in the fleet;

Liu Juntao named the warships of this class as the dynasty class, and the ships of the previous dynasties, such as the Han, Tang, Song, Ming, etc., must be Chinese orthodoxy.

A third-class battleship must have forty to sixty guns, two gun decks, and is the general main battleship of the fleet;

Liu Juntao named this class of warships the Emperor class, and named the ships after the emperors of the Chinese dynasties, such as Emperor Wu of the Han Dynasty and Taizong of the Tang Dynasty.

Most of the remaining Tier 4 to Tier 6 warships are supplementary warships, which are not considered the main force of the fleet.

Fourth-tier battleships must have more than thirty guns, mainly frigates with single-deck guns, to complete the chores of the fleet. Such as reconnaissance, transporting crews, piloting, patrolling, capturing merchant ships, and much more.

The fourth-class battleship is also the most built warship in the navy in the future, because this type of warship has low cost, wide use, and moderate firepower, which can be said to be a very cost-effective warship;

Liu Juntao named the warships of this class as the prefecture and county level, and took the prefectures and counties of the Ming Dynasty as the ship names.

Tier 5 warships must have more than 18 guns, and Class 6 warships must have more than 10 guns, both of which will be small auxiliary or information-transmitting ships for the fleet.

Liu Juntao named this class of warships the Jianghe class, and named the ships after the mountains and rivers in various parts of China.

At the same time, Liu Juntao also took out all kinds of new tactics and regulations that he had summarized on the road, and asked Feng Xiang to implement them immediately.

Among them, Liu Juntao emphasized the "battle line" tactics, now even the Western navy has not yet developed a mature battle line tactics, Liu Juntao is ready to let his navy walk in front of the West!

"Starting tomorrow, the navy will use the existing warships for drills, and those who do not qualify, whether they are captains or sailors, will be expelled from the navy!"

Hearing Liu Juntao's order, Feng Xiang and the generals were all dumbfounded.

In fact, along with the change of naval tactics on Dongping Island, new warships that have been finalized have also been developed.

Especially in the structure of the stern of the battleship, the circular structure of the treasure ship, which was abandoned more than a dozen years ago, was readopted. On earlier seagoing vessels, the deck was bent in the same curve because the outer liner and rim were curved. Now the battleship adopted a straight deck, and the curves of the liner and the rim were interrupted by the gun doors.

Liu Juntao made the warships he built with a lot of artillery, so that the draft of the new warships was ~ deep. Such a warship can still provide a better firepower carrier in higher waves.

Liu Juntao also knows a little about the Dutch warships, and now the Dutch warships should generally be lighter and have a shallower draft (due to the terrain of the Netherlands) compared to this new type of warship, which makes their warships very flexible, but they will be more vulnerable in battle.

Moreover, Liu Juntao still vaguely remembers that in the first half of the 17th century, the largest warships in service in Western countries were mostly double-decked, and the carrying capacity was generally about 50 to 70 guns (the serious monster of British "maritime sovereignty" is a special case, so let's not talk about it for the time being).

For example, the "San Francisco", which was commissioned by Spain in 1617, was equipped with 50 heavy guns, but the specific configuration is unknown;

The French "Royal" in service in 1627: 18 24-pounder guns on the lower deck, 18 18-pounder guns on the upper deck, 10 12-pounder guns on the bow and stern decks, and 6 36-pounder guns in the shooting holes under the stern;

It was not until the second half of the 17th century that Western countries successively had giant warships with three decks in service, and the number of guns carried exceeded 100 one after another.

For example, the "Santa Maria de Concepción", which was commissioned by Spain in 1662: the lower deck was equipped with 28 24-pounder guns, the middle deck was equipped with 28 18-pounder guns, the upper gun deck was equipped with 28 8-pounder guns, and the top open deck was equipped with 6-8 pounder guns;

The French "Royal Louis" in service in 1669: 30 36-pounder guns on the lower gun deck, 30 18-pounder guns on the middle gun deck, 32 12-pounder guns on the upper gun deck, and 26 4-6-pounder guns on the bow and stern open deck (the upper gun deck was cut to 26 12-pounder guns and the bow and stern open deck to 6 4-pounder guns due to the unstable center of gravity soon after);

The "Sun King" commissioned in France in 1671: 28 36-pounder guns on the lower deck, 30 18-pounder guns on the middle deck, 30 12-pounder guns on the upper deck, 12 6-pounder guns in the stern gun mount, and 4 4-pounder guns on the bow open deck;

The Seven Provinces, launched in 1665 (the exact date of service is unknown, but certainly no later than 1 June 1666, when it first entered the war), was armed with 12 36-pounder guns and 16 24-pounder guns on the lower deck, 14 18-pounder guns and 12 12-pounder guns on the upper deck, and 26 6-pounder guns on the bow and stern open deck.

These are already two hundred years later, and now Liu Juntao has designed the warships of the Dongping Island Navy in this way, which is already a super-speed development.

Now Liu Juntao's only worry is that the number of sailors and artillery cannot keep up with the speed of naval development!

Liu Juntao stayed in Andongwei for three months, during which Tang Yu raised another four million taels of silver through the Yushan ticket number, and Hu Dexing, the chief military officer of Shandong Town, also organized a large number of shipbuilders to double the scale of the three shipyards in Rizhao County!

At this time, all the new warships of the Dongping Island Navy began to be built in three shipyards in Rizhao County, and Andongwei's two battleship repair factories also began to assist in the construction.

Three months later, Liu Juntao left Anton Wei and hurriedly returned to Datong Town.

However, in the months after Liu Juntao left, more than 20 new warships were built in Rizhao County and Andongwei like dumplings, and several military bureaus in Shandong Town also urgently sent stocks and newly built 300 guns, rockets, 10,000 enemies and other weapons.

Of course, that's all for later.
