The old gate ship has a gun deck, which is equipped with six 12-pounder guns made by Huang on the left and right sides of the ship according to the design requirements, and one 18-pounder gun at the bow and stern.

Having fourteen heavy guns is already the limit of this ship type, and even then it is more than twice as powerful as the main battleship of the Ming Dynasty.

The number of guns with a displacement of 400 tons remained the same, but the caliber of the cannons decreased accordingly, and the main guns were twelve six-pounder guns and two twelve-pounder guns.

The 300-ton ship was armed with a total of eight guns, the largest caliber of which was 12-pounder bow and stern, and the remaining six were six-pounder guns.

There were not many artillery pieces produced, and the city defenses had to be arranged, and the infantry had to be equipped.

Huang Han was equipped with one ship with a displacement of 500 tons, two ships with a displacement of 400 tons, and four ships with a displacement of 300 tons, a total of seven old lock ships as the main combat ships of the "Red Banner Army" Naval Division.

Fifteen old lock ships were launched, and more ships were being built in the dockyard in the future, because the craftsmen were familiar with the hands, and the number of personnel increased, and it is estimated that the output in the second half of the year will increase by more than half, and at least 20 more ships will be launched next spring, and the annual output will continue to rise in the future.

During this time, Huang Han personally went to sea on the old lock ship to test the speed and stability of this new ship type, and found that this is after all a technology that has been verified by later generations, which is relatively reliable, and it is indeed concentrated, and many advantages of Western ships are two percent faster than the Fu ship of the same displacement.

When Huang Han practiced on the ship, he often discussed the most advanced technology of this era with the shipbuilders led by Fu Wang Yuqi, the master of Longjiang Shipyard.

Who knew that these great craftsmen respected Huang Han like a god, because the drawings of the fifteen old lock ships of the three classes they built were perfected on the basis of the sketches provided by Huang Han.

Originally, they were a little apprehensive when they saw that the master of the family was not afraid of failure and arranged and built fifteen new ships at once, but now it has been proved that this kind of ship is ancient and unprecedented, and of course they admire it to the ground.

Huang Han is still slow ship, he is thinking about how to increase the power of the old lock ship, the history of ship development, as a modern person knows that the most important turning point is the emergence of the steam engine, and also knows that the original steam engine speed can not meet the requirements of driving the propeller, so it is the wheel propeller that is driven.

It is too early to open the golden finger to let the steam engine come out, which requires a process of slow development and accumulation, but the speed of the ship is an important link in whether it can dominate the China Sea in the future.

Because there is now a powerful force in the Chinese sea - Zheng Zhilong's pirate group.

This person went to Zhao'an the year before last and became a guerrilla general of the Ming coastal defense, and the pirates who put on official clothes will of course become more violent, and he attacks and recruits other pirates, and there is already a tendency to dominate the China Sea.

It is said that Zheng Zhilong has thousands of large and small sea ships, tens of thousands of people and horses, and his annual income exceeds 10 million taels of silver.

Huang Han clearly knew that Zheng Zhilong was a speculator and a traitor with no ambitions, he did not have the slightest sense of national honor, and took the initiative to shave his head and surrender to the Manchu Qing Dynasty, and in the end he was stabbed, and the family he took to the Qing Dynasty was also killed cleanly.

Zheng Zhilong's most glorious time was when the Ming Dynasty was about to fall, he controlled the sea routes, collected port fees and protection fees for merchant ships from various countries, and a large deck ship in the West needed to pay 3,000 taels of silver. Each ship earns 3,000 gold, and the annual income is 10 million, so it is rich and rivals the country. “

I really don't know where this kid earns twice the Ming tax every year, and where does the silver go?

If Huang Han gets such huge profits every year, he will definitely use it to build more warships and merchant ships, train more knowledgeable young gunners and sailors, and it is indispensable for colonization all over the world.

How could there be no powerful navy in the Age of Discovery? Replacing Zheng Zhilong to seize the interests of maritime trade is the highlight of the 10-year development plan of the "Red Banner Army".

While discussing techniques with master craftsmen, Huang Han drew many creative sketches casually.

Among them, the sketch of using the pedal drive chain to drive the "wheeled paddle" was sought after by Wang Yuqi and other shipbuilding craftsmen.

The Ming Dynasty has already had its own built ship, called "wheel boat", it is the warship of the Ming Dynasty sailors to hit the water with wheeled oars, four or five zhang long, more than one zhang wide, about one foot of the outer imaginary frame, four wheel slurry inside, the head of the wheel into the water is about one foot more, and the speed of the ship is much faster than the oar.

Presumably, these craftsmen saw the sketches of the head of the family and thought of their commonplace "wheels".

The speed of the "wheel pulp" is limited by the speed of the "wheel pulp" and the boat is directly rowed by the oarsman.

Huang Han's design of multi-person pedaling led to a multi-chain drive gear to drive a steel shaft to quickly rotate into the power of "wheel pulp", this idea was seen by these shipbuilding masters, these people have their own ideas in their hearts, everyone scratches their ears and cheeks and is eager to try.

Seeing that the shipbuilders were in high spirits, Huang Han smiled, he encouraged everyone to brainstorm, and agreed that they would work together to develop and develop, and the masters whose design plans were adopted would be treated as the chief flag officer of the seventh grade and issued the regular uniform of the seven-rank military attaché.

Such a generous reward made the shipbuilders even more impatient, because everyone wanted to wear official uniforms and become official masters.

Huang Han instructed to design eight "wheeled pulp" to improve a 500-ton old lock ship, and no matter how much money was spent during the investment period, he did not care.

As long as the new steamer can be driven by human power without wind and ignoring the speed of the sea, it will be a victory.

Of course, the speed of ships in the Ming Dynasty was not calculated by knots, and Huang Han's request to the craftsmen was to rely on manpower to advance more than ten miles in half an hour.

Back in the "Tiger's Den" city, Wang Yuqi took the craftsmen to improve the drawings, and the steel factory received the task of producing steel shafts, chains and gears.

The world's most primitive steamship is built by the Han people, and when it developed to the Ming Dynasty, there was such a warship as "Wheel Boat", Huang Han opened the golden finger to use the method of chain drive shaft to improve, I believe that it will not be long before a new generation of ships will be born.

It is not necessary for the ship to be used as a cargo ship, because it is cost-effective to arrange dozens or hundreds of people to drive the wind power without cost.

The steamers were all battleships and passenger ships, because when the ships were sailing on the sea, the marines, including the gunners, had basically nothing to do on the boats, and everyone took turns to pedal to increase the speed of the ship and exercise their bodies by the way.

When the passenger ship is sailing, it is completely possible to mobilize idle passengers to interact, as long as the ticket money of those who are willing to contribute can be appropriately discounted, and it is estimated that it is easy to obtain a large amount of cheap labor.
