On the north bank of the Yangtze River, east of Badong County, Huangzhou, the lakeside shipyard, Yuwen Wen, who is stationed in Huangzhou, visited a dry dock here. In the dry dock, a new warship has been built. Workers are packing up all kinds of utensils and materials and moving it out of the dock.

Yuwen Wen stood by the dock and looked at the warship with interesting interest. The "drawing warship" he designed himself has now turned into reality, and he couldn't help but feel a little excited.

The "Shu" class impact cruiser, iron rib (with iron keel) wooden shell ship, displacement of 12,000 hu, steam power, rear-mounted paddles, machine sails, steam powered sails.

The bow of the ship is an empty warehouse, with iron collision angles below its waterline. There are three special "razors" on both sides of the bow, which are specially "cutting the ship". When charging, the maximum speed of sailing against the current (on the Yangtze River) is 22 miles per hour, and the speed of the water is 28 miles per hour, with a duration of one hour.

The hull has a single-layer gun deck, and there are ten small-caliber artillery pieces on the left and starboard. These artillery mainly fires shotguns, mainly killing enemy clutches and personnel.

There are rotatable steam injection ports on the bow, stern and sides of the ship, which can deal with the fast ships close to the ship, or against the enemy troops who jump to board the ship.

There are also large squirt pumps that can deal with fire boats and can also be used to put out fires.

Such a weird design naturally has its tactical purpose. The typical tactic of impacting cruise ships is to collide as a vanguard when the enemy and our navy fight to the decisive battle.

The rapid charge begins (no more than one hour), quickly approach the enemy's impact cruise ship, use steam and water spray to spray against enemy clutches and fire ships, and after breaking through and intercepting, it directly crashes into the enemy's main warship.

The iron impact angle is enough to knock out the part below the waterline of the enemy warship, and the impact angle can fall off at any time according to demand.

If the enemy warship is a steamer, the "wheel-cutting" tactic can also be adopted, which is to collide with the enemy ship and directly destroy the oars on the port or starboard side.

Based on the above reasons, the rear position of the oar that hits the cruiser is to avoid impact.

No matter which collision method is used, the impact cruise ship that crashes into the enemy ship array will open fire on both sides of the left and right sides, directly killing soldiers approaching the enemy ship, disrupting the enemy ship array, creating opportunities for subsequent breakthroughs of the main battleship.

Such a warship that was running wildly was actually an excellent vanguard for the Great Zhou Navy to assault the enemy.

However, it can only be used in the inland river and cannot enter the sea...

Yuwen Wen thought so, and looked at the masterpiece that was about to be launched, and felt a little regretful.

The wind and waves on the sea are very strong, and the paddles are easily damaged. Because they are too bumpy, the boats are swinging left and right (rolling horizontally), which causes the paddles to often appear on the water surface, so the paddles are very low in paddle efficiency.

In view of this, steamships are now riverboats.

Yuwen Wen felt a little regretful about this. Of course, the propulsion is not as efficient as the propulsion, but the technical difficulties of propulsion are not so easy to make breakthroughs.

According to general understanding, the greater the blades and speed of the propeller, the greater the thrust. However, to achieve this, the power to drive the propeller to rotate must be strong enough to overcome the water resistance and allow the large propeller to rotate quickly. With current technical capabilities, it is a difficult goal to achieve.

Pure speed amplification can be achieved by relying on the gear set, but without strong power, the propeller cannot rotate fast in the water, and there is no way to talk about strong thrust.

Even so, steamships are also an amazing "invention". They can be said to be a timely help. As for propeller propulsion, they are icing on the cake.

Yuwen Wen was feeling that all the personnel in the dock had been evacuated. After confirming that the water valve was opened and water began to enter the dock.

At the same time, there are four pipe outlets for water release. The water level in the dry dock quickly rises and becomes a wet dock. The ships that were originally parked on the trough gradually "rise in the water."

Yuwen Wen looked silently, watching the warship with a full load of 12,000 hu of water float up.

Hu (stone), originally a unit of capacity, is equal to ten dou, and one dou is equal to ten liters, so one gua is equal to one hundred liters.

At this time, the rise is definitely not directly equated with the "rise" in later generations, but Yu Wen Wen made a rough conversion in order to facilitate his own understanding:

In later generations, a "ton" of water is equal to one thousand "liters" of water. Therefore, a collision cruiser with a full load displacement of 12,000 hu sounds very majestic, but in fact it is a "bumper ship" with a displacement of about 1,000 tons.

But even the "bumper ship" is an extraordinary warship in this era, and it is enough to shock ghosts and monsters.

Yuwen Wen has always believed that although the world is peaceful now, the military preparations of the Central Plains cannot be relaxed, so the official navy must "keep up with the times" and update the warships in a timely manner.

In the Yangtze River Basin, if an army suddenly rebels, or local tyrants raise anti-flags, the rebels snatch the steamship as warships, and the navy, who do not have the warships in hand, would be embarrassed.

Yuwen Wen did not think that there would be a large-scale rebellion, nor did he think that there would be a rebel that could sweep the world. However, if the court could not suppress the rebellion as soon as possible, the country and the people would suffer a lot, so necessary military preparations should be provided and will come in handy immediately when needed.

We must never be like the Jin Dynasty, after unifying the world, think we can rest assured, so we disbanded the soldiers of the prefectures and counties, put swords and guns into the warehouse, and put horses in the south mountain.

He felt that people without long-term thinking would have immediate worries. Not to mention elsewhere, the court must firmly control the control of the Yangtze River Basin.

Once someone rebelled and tried to rule the river and reappeared the confrontation between the Southern and Northern Dynasties, its primary goal would inevitably be to control the river defense.

Therefore, except for one that can build a steamship, there is one in Wuchang, Ezhou, the rest is on the north bank of the Yangtze River.

In the future, even if someone rebels, sweeping or roaming across the Yangtze River, he could not build a steamship. The rebels could not compete for the control of the Yangtze River by relying on traditional sailing ships.

Or, if a certain ship dealer suddenly raises the matter, and soon after the incident, he controls a large number of steamships, trying to separate the country from all over the country, then the navy of the government army, which is already equipped with steam warships, will give the other party a headache.

Because civilian steamships cannot fight against impact cruisers, let alone steam-powered gunboats.

Yuwen Wen personally designed the warship, the main purpose was not to enjoy it, but to have actual needs. He wanted to ensure that there were always reliable naval troops stationed on the Yangtze River, and to ensure that the navy could attack at any time, so that those ghosts and monsters would put aside their thoughts.

This idea was implemented as the impact cruise ships were launched one after another, and the navy equipped with steam warships did not stay in the military port on weekdays.

The Yangtze River shipping will surely become more and more busy. Maintaining order on the river and cracking down on robbers and water bandits is also the unshirkable responsibility of the government. Before the formal water law enforcement forces are established, all prefectures and counties along the Yangtze River need strong assistance from the official navy to maintain water security.

“Woooooooooooooooooo~~~~~”

The sound of the whistle sounded, pulling Yuwen Wen's vision back to the dock. At this time, the water level inside and outside the dock was almost flat. The lock was opened, and the warship that had already been preheated by the boiler was ignited, and the oars at the rear began to rotate.
