This battleship is actually very different from the battleship that Li Yuanjing had in mind.

At present, the roughly calculated empty weight is more than 90,000 stones, what is this concept?

That's about 5,000 tons.

This tonnage is naturally nothing in the later generations, but now it is Datang.

How much steel is produced in a year?

In order to build this ship, Li Yuanjing almost hollowed out the steel workshops in the surrounding area.

This is also the reason why Li Shimin keeps complaining that he eats too many resources.

You must know that Datang's steel is not just for him to play with, although the blast furnace ironmaking method has improved Datang's iron-smelting level by several steps.

The advent of various professional mining truck machinery has also improved the quality of iron ore mining.

But one ship eats the output of nearly ten iron-smelting workshops, and this Datang is still unbearable, and Datang also has to make all kinds of farm tools and machinery, which are all big iron eaters.

If Li Shimin hadn't felt that he owed something to Li Yuanjing, he would have ordered the construction to be stopped a long time ago.

However, although Li Shimin did not give the order, he also clearly informed Li Yuanjing that this was the only time, that is, he had no chance to build the next one.

In fact, in Li Yuanjing's estimate, the ship was about 3,000 tons.

The reason why there are so many exceedances is that the welding method causes the exceedance, and the second is that many places are very solid, mainly because the designers are worried that the strength is not enough.

Don't expect handmade things to be fine, everything is just going to be strong and durable, so that here is a little bit over-standard, there is a little bit of over-standard, and then there is no then.

"At present, the biggest problem is the corrosion resistance, the part above the water surface is easy to say, just replenish the paint at any time, but the part below the water surface is not easy to deal with." Li Yuanjing slowly said the problem of this ship.

He continued: "According to the results of the material experiments that have been researched so far, the underwater part can be guaranteed to be undamaged for up to ten months, that is, if it is sailing, it is necessary to enter the dock for underwater parts cleaning and replenishing paint for a maximum of half a year."

Therefore, the next focus should be on the research breakthrough of coatings, and make better coatings as much as possible, so as to reduce the return of ships to the factory for overhaul. ”

"Half a year?" Li Jing couldn't help frowning.

"Is it troublesome?" Li Chengqian didn't know much about it, but looking at Li Jing's expression, he also knew that the problem didn't seem to be simple.

"It's a hassle!" Li Jing nodded: "Half a year, according to the current speed and situation, if you start from Haizhou and don't stop too much in the middle, you can probably run two laps around the previous route, which will take about seven to eight months, and the ship returns to the dock for repairs is not just docking, but to clean up the water in the dock, and then manually go down to repair a little bit, how can this process take two months?" ”

"Two months is not necessary, if the problem is not serious, a month is about the same, a slightly more serious one and a half months is enough, in fact, it is to shovel off the attachment on the bottom of the ship, and then polish the rusty part, apply paint, and wait for drying, this is just basic maintenance, if there is a problem with the steam engine, it is the real overhaul." Li Yuanjing shook his head and denied.

The speed of this work depends on how many people are sent to do it, the technical difficulty is almost non-existent, it is more laborious and scrap labor, there are not so many machinery, only a little manual shovel, if there are enough people to do it, for example, send 500 people to clean up, about two or three days can be cleaned.

It will take another two or three days to deal with the rust, then apply the paint, leave it for half a month and wait for him to dry thoroughly, plus the previous pumping, etc., and it will not even take a month to get it.

"Would you like to go up and feel it?" Li Yuanjing looked at Li Chengqian and asked.

Li Chengqian nodded subconsciously, how could he not want to go up and experience such a bad thing?

Li Yuanjing smiled, and immediately ordered people to order the battleship that was on trial voyage to return, and at the same time ordered people to prepare a target ship.

It is not easy to find a target ship, after all, it has not been long since Datang opened the era of sailing, and the oldest ship that can be found in Haizhou is only six or seven years old, and it is still far from retirement.

As for the newly built ship, don't even think about this, it's useless yet, how can it be used as a target ship for you?

Fortunately, the fleet is also from the imperial court, and Li Yuanjing has already greeted the fleet before, promising to give them a new ship as compensation within two months, which directly pulled an old-fashioned wooden ship that had just finished unloading from the fleet.

Standing in the command cabin of the battleship, Li Chengqian actually had a feeling of seeing the mountains at a glance, it was not that he had never been on a ship, but he had never been so stable as this time.

Not to mention that it was flat on the ground, but at least I didn't feel much shaking.

The battleship first sailed into the distance, not in a hurry to hit the target ship, and when the speed of the battleship increased, it began to make various movements.

The speed is not as good as those wooden ships with steam engines, but it is very stable, and people feel very relieved when they stand on it.

After playing on the sea for about half an hour, Li Yuanjing ordered to crash into the target ship.

At this moment, the target ship was already ready, anchored, and all the people on board were evacuated to the shore.

Li Chengqian was a little nervous at this moment, after all, it was a collision with a boat, and if he hit it like this, something would happen.

Before I knew it, the back of my palms was full of sweat.

However, the battleship did not stop advancing because of Li Chengqian's nervousness.

'Bang! ’

There was a dull sound, and Li Chengqian did not see the two ships colliding in his sight, but he saw that the target ship on the opposite side was shaking significantly.

The battleship's huge inertia rushed forward sharply, and only then did it see the bow collide with the opposite side.

Then an incredible scene appeared, the target ship that was still in use on the opposite side and had just been pulled was directly loaded into two.

And Li Chengqian only felt a slight pause on this ship, and all this in front of him was simply incredible.

After the ship docked, Li Chengqian ran to the bow of the ship in horror and took a closer look, and found that there were only some less serious impact marks, and after stopping on the shore, Li Chengqian also knew why he felt the impact first and did not see the impact.

There is a prominent collision angle below the waterline at the bottom of the bow, and it is here that it collides with the other party first.

"How's the ship?" Li Yuanjing looked at Li Chengqian with a smile and asked.

"It's amazing, I can't think of any words to describe him!" Li Chengqian nodded dumbfoundedly.

"This king also thinks so, so this king plans to dedicate this ship to His Majesty, as for the name, this king thinks it is good to call the Tang Emperor......"

"What?" Li Chengqian looked at Li Yuanjing in surprise.

"Datang needs this ship more than this king, and the first ship of Datang naturally wants to be His Majesty's!"
