The development of the eight-year and nine-year styles of Chongzhen were both smooth. By the ten-year style, the Ming Dynasty's technology seemed to have encountered a bottleneck.

Not only did the construction progress double, but the quality was also not satisfactory. As the flagship of the First Fleet, more than ten small water seepage accidents occurred when they arrived in Manila.

Among them, more than 300 opinions on unreasonable ship design and needing improvement were sorted out.

Zhu Cilang also understood that after all, the eight-year and nine-year style are a kind of technical catch-up. With the combination of European experience and Ming shipbuilding experience, the construction of the first two ships was smooth.

The ten-year-old style is innovation. Even the warships of the same era as the ten-year-old style are also the most cutting-edge technology of Europa.

The Ming Dynasty had not built such a large ship, but had never built such a large warship.

No one expected that the force the hull would be subjected to double for every inch of the muzzle, and Daming did not know that the recoil roll coefficient of the gun could reach more than ten degrees.

Then there are nails. When the boat is small, the nails will become firm when they are nailed into it. However, when the boat is big, the hull swings back and forth, and the vibration of the cannon shooting, it is easy for the nails to collapse.

So I had to use riveting, and then I found that riveting was not that easy. The riveting head was easily corroded by sea water. It took a lot of time and energy to repair a large ship of more than 3,000 tons every time I boarded the boat to repair it.

If the rivets cannot last for a year, they cannot be used on the boat.

The ten-year stance is fine. Although it was a bottleneck in the Ming Dynasty technology, it was still built after chasing it. After the efforts of craftsmen, energy was also produced.

However, the twelve-year stance of difficult labor may have to wait until next year becomes a two-year revival.

This requires the integration of the shipbuilding technology of the Ming Dynasty before breaking through! All the experiences need to be questioned on this big guy.

Without the update of technology, we can only rely on craftsmen's experiments to confirm that there is no problem with every step and part.

For example, the thickness of the sail, the area, the thickness of the rope, the stability of the anchor, the recoil of the artillery fire, and even the water pressure at the bottom of the ship after drainage, etc.

This is not just a ship, it is an innovation in the shipbuilding industry in the Ming Dynasty. In this era, no one can represent the technology and craftsmanship of a country.

The flagship has little practical significance, but it represents national strength. According to the experience of using weapons in later generations, the best and most advanced ones can be small in quantity, but they cannot be bought.

Of course, in terms of practicality, it can still be built in large quantities, and the power and cost are balanced, and it is just the main force of the fleet to use it together.

Ten years of play the role of flagship, he represents the national strength and face of the Ming Dynasty. He drove him out, and his huge body and dense gun barrels were the greatest deterrent to the enemy.

The most cost-effective ship in the Ming Dynasty is the eight-year-old Chongzhen style. After improvement and private shipyards assist in building ship hulls, the construction cost of such ships has been minimized.

The private shipyards have also promoted their own technological progress by absorbing new technologies in the construction of the ship.

For example, a new lucky ship appeared in Jiangnan this year, which imitated the Garen ship in appearance, and the sails also had both soft and hard.

Without Zhu Cilang's participation, Spain had already begun to decline. From this time on, the dispute between Britain and the Netherlands was the core contradiction in the second half of the 17th century.

It was also at this time that shipbuilding technology developed rapidly, battle line tactics began to mature, and battleship hierarchy system was established.

Zhu Cixuan made a clever trick. The Ming Dynasty first established a hierarchical system and proposed a battle line tactic.

When the sail battleships reached their peak in history, there were once giant beasts with a displacement of more than 5,000 tons of four-layer cannon windows.

However, the UK used naval guns to teach Spain and France a truth, the most suitable one is the best. If you just want to be big, you will only end up being embarrassed.

Therefore, the twelve-year-old style is not a big worry. Zhu Cixuan's plan is to promote the progress of the shipbuilding industry in the Ming Dynasty by promoting the ten-year-old style of construction.

If ten-year-old batch construction is built, the cost of nine-year-old will definitely be further reduced.

When the war started with Spain, in the main fleet of ten-year and nine-year, each fleet had one to two larger revival two-year-olds, just one level higher than the current First Fleet.

Later, with the increase in ship tonnage and the application of new technologies, warship construction no longer pursues more artillery, but instead changes to larger artillery.

Until the era of Iron-Crafted Ship and then to the era of giant ships and cannons, this was a complete technological evolution process.

Back at the ship model room, Zhu Ciyang saw that the latest design of the Ming Dynasty was the twelve-year-old style. The ship that had been finalized was changed, entirely because of the contribution of the last Da Ryukyu naval battle.

The Netherlands is worthy of the title of a sea coachman. Only a dozen ships are not as good as the Ming Dynasty in terms of firepower and tonnage, but the firepower density of their single ships is not weaker than that of the Ming Dynasty with more than a dozen guns.

Moreover, in terms of ship flexibility and speed, the Ming Dynasty might not have won the battle if it weren't for the Ming Dynasty's many ships using the method of siege.

If the same number of Ming warships and Dutch warships fight, the loss will definitely be the Ming warships.

From this naval battle, the Ming Dynasty discovered its shortcomings and improved its ship flexibility and speed. Not only was the twelve-year style redesigned, but the eight-year and nine-year styles were improved accordingly.

Judging from the ship model, the new twelve hull was lengthened again, and the bow absorbed the successful experience of flying fish-level, and used the fly-cut head and square tail to make the hull's center of gravity lower, further reducing the buildings on Class A.

The manager's introduction: "Now, wait for the new gun to be successfully tested. If the new gun is successful, the combat effectiveness of the new ship will double.

The new cannon that the manager mentioned was a rifled gun. With the increasing maturity of the Ming Dynasty's steelmaking technology and the quality of steel has been further improved, and steel cannons have begun to gradually replace cast iron cannons.

The navy does not have such high requirements for mobility, so it has more choices. The artillery factory designed a new type of artillery based on the Minnie bomb principle proposed by Zhu Cixuan. After the penetration of the Minnie bomb and the rifle have greatly increased, the flowering bomb has become possible.

Before the emergence of the flowering bomb, even if the battleships are fired in a row, it is very troublesome to sink the opponent's ship.

Even in the 18th century, the battle of jumping bang was still an important subject in naval warfare.

It was not until the flowering bomb appeared that the method of naval battle was completely rewritten. The result of the artillery battle was no longer one side carried a hole back to sail, but was broken and sunk.

Therefore, the Ming Dynasty needed flowering bullets. Only warships that used flowering bullets were real battleships. Instead of, in order to destroy enemy ships, the Ming Dynasty battleships also had to prepare rockets and crossbows.

However, Zhu Cixuan only knew the principles and knew nothing about technical materials, so the artillery factory started research and development of this new weapon after receiving the order.

Before the technical parameters and operating guidelines of the new gun are determined, the battleship cannot be finalized in advance. What if the gun position is not kept correctly and cannot be installed? What if the gun window is too small? What if there are any new steps and the gun position is not reserved for the operation position?
