"Oh, so this is supersonic. ......"

Jin and Reiko are flying overhead in Pegasus 1.

At the moment, the maximum speed is 3600 kilometers per hour, or about Mach 3. This is calculated based on the results of the measurements taken by the Magi Radar.

In the vacuum created by the wind-shield, the speed can be increased as much as possible, but there is a limit.

That is, the speed at which the boundary is generated.

At speeds over 3,600 kilometers per hour, the speed at which the warding was created could not keep up, and the nose of Pegasus 1 would be outside the warding.

"But that's still an unbelievable speed," he says.

The speed of making a round of this planet, Ars, in two hours is certainly an unbelievable speed.

After enjoying the supersonic speed for a while, Jin decides to modify other air forces after landing.

Once Jin builds them and registers them in the control core for the old man's memory, the craftsmen (smiths) will build them for him.

Thus, all aircraft would be equipped with force field generators, eliminating the need to glide for takeoff.

"Of course, it can also be used for ships and golems."

Hydro boats and Mermaid Golem were modified first. The Mermaid's top speed reaches 500 kilometers per hour thanks to its underwater water avoidance wards.

Here, Jin has to reflect on his actions and take a lesson to himself.

"Old man, what about the three aircraft carriers?"

The 20,000-ton class aircraft carriers began to be built during the war against the Unification Party (Unifiler). The first of them, the , had already been completed.

and the third ship have also been completed, Myoko is at Tatsumi Bay and Asama is still in dock, waiting for the launching ceremony.

"Oh?　I didn't know that. ......"

I had been to Tatsumi Bay earlier for Reiko's test, but I didn't notice it. I was probably too engrossed in the test.

"...... That's all right, old man, but I need to talk to you about something."

"The need for an aircraft carrier.

The carrier was built because it was inefficient to launch air power from Horai Island every time, but the Unification Party (Unifiler) was dismantled before it was ever used.

With the completion of the transporter, it was now possible to launch a sortie instantly and to any place, not to mention returning home.

"......It's my fault for having done it on the spur of the moment, though."

<<>

The old man follows Jin. Jin could not help but feel that he was being told something slightly out of line, but he decided to change his mind.

"Well, there is nothing more to say. ...... So, what I'm asking is if we should modify the three vessels."

<>

"What I'm thinking of is a < so to speak."

As a weapon, a versatile ship is certainly useful, but it has the disadvantage of lacking the decisive power. In other words, it falls into the category of a general-purpose ship rather than a versatile ship.

However, since it was made by Jin, it was thought that at least this concern would be as small as possible.

The old man will consider the advantages and disadvantages of the project before he responds.

>

"That's the thing. ......3 I also think that we should try to make a trimaran type ship by using the right number of ships. ......"

<<>

The three ships together would be 60,000 tons, maybe 70,000 tons if you consider the connected decks and so on. That would be more than the former superdreadnought battleship .

"Yes, I know. That's why I'm wondering. ......"

"Father, why don't you start an invincible fleet?"

Reiko, who had been listening in silence, interrupted.

"......I'm sure your father remembers ...... destroyers, light cruisers, heavy cruisers, cruisers, battleships, aircraft carriers, craft, supply ships, submarines, minesweepers.... ...etc.?"

"I don't think that's a good idea."

Immediately, Hitoshi said no.

I understand Reiko's feelings and I would like to build one, but I don't think there is any use for it. Even in World War II, carriers and aircraft were more important than battleships.

If you are thinking of fighting, it is more advantageous to have more air power. If you do not intend to fight, then the fleet is useless.

"......Yes, that's true."

There is the example of Reiko. Jin has a character to cherish what he likes.

Jin nodded his head at the old man's suggestion.

"Ah, I see. ......, for example, going to the potlocks?"

<<<

That's the important point. In terms of aircraft, it would be the equivalent of an airship. If you can't show it in public, you can't use it in many situations.

"I would like to visit Potlock and Eckert's place. And then there are the demons' territorial waters. I can think of a few other uses, like catching fish and transporting them to help with famine.

<<

"Yes. ......"

Jin thought about it. I don't want to do anything halfway. But I don't want to make something that can't be used.

"I guess we'll have to make a few ships of different sizes. ......"

Anything less than 10 meters would be uninhabitable. 20 meters would be halfway.

"If we assume ......, it would be about 50 meters?"

The ship being built by Eckart Tekles, a wealthy merchant in the southern part of the Kingdom of Selroa, was 40 meters long. 50 meters would be within the norm, somehow.

<>

"Hydro class."

The minimum number of vessels is two. Jin thought this was well within the bounds of common sense and gathered his thoughts.

"Father, where do you think such a big ship was made?"

"Oh, ......"

The location of Horai Island is a secret. It would be possible to claim that it is owned by deus ex machina, but it would be tough to claim that it is owned by Jin.

"Oh, ......, there are so many problems."

Unlike airplanes, this is a highly visible object, so there is a risk that it could be deceptive.

<>

The old man, who could not see Jin's concern, decided to make a proposal.

> "That's not bad.

"That's not a bad idea."

<

On modern Earth, that size would be a destroyer, but the old man continues.

>.

Jin wondered what the old man was going to fight against, but then he thought about it, the sea power was certainly lacking compared to the air power.

"I'll leave that to ....... But what do I want?"

Certainly, it would be easier to form an image if you see the real thing in front of you. Jin allowed it.

"Then, start working on the first ship for each of them right away."

"Well, we named the aircraft carrier and battleship after mountains, the cruiser after a river, and the destroyer after a fish.

"Wait a minute. Let's not have a fish for a destroyer. It's too different from the image.

<

"Let's number the Destroyer series like the Hydro series. How about the series name is ......<>?

Like the Hydro series, it is a very good name.

Thus, the fleet to protect Horai Island was fully launched.

On the other hand, Jin was still worrying about what to do with his own ship.

(If Erza were here, I could consult with her.)

Jin felt that the absence of Elsa, who was always around, was somehow lonely.

As if to get rid of this feeling, Jin was absorbed in the ship.
