I'm the one who just got on the submarine.

The Crocodile class submarine is 62 metres long and has a reference drainage of 920 tonnes. It is equipped with a Terra Fidelitia magic spray engine and sails 15 knots over the water and 19.1 knots underwater.

Looks like a very ordinary military submarine. Not that big, mediocre. It's just a very quiet ship with no screws.

Armed with a 76mm plasma cannon enclosed on the bow deck. Two 20mm ray machine guns of the same containment type, equipped with four 45cm torpedo firing tubes at the bow, one at the stern and twenty total torpedoes.

Basic operations are reconnaissance and trade sabotage. It is equipped with a plasma cannon, albeit containment, to quench torpedoes and destroy enemy merchant ships on the water.

At world level today, it is an attack that can be carried out because there is little means of launching an effective attack on a surfaced submarine.

If the other side shoots back, it's dangerous and you can't shoot it up.

In the shapeshifter crew and the submarine that operates the copy core, me and Mr. Bell have nothing but to keep an eye on and focus on command.

Crocodile class submarine that joins the deployed Vulcan Golem submarine unit and proceeds at periscope depth. I'll peek into the periscope and see what's going on at sea.

Only a cylindrical telescope on the surface of the sea, and the hull is in the sea. It's just that when the sea level is beautiful, you can see the submarine silhouette from directly above. Well, unless a ship passes up there, you'll only see a periscope from aboard.

"... All right, all right, as you can tell. An Imperial Navy ship."

"Show me, too."

"In a cat, you see a periscope?

I'll support Mr. Bell's body and match the position of the periscope. Black cat grabbing handle with forefoot and peeking in.... If Early were here, you would have taken a picture of this.

"Hum hum hum. Is that the ship that moves in the Reciprocal Engine?

"Oh, wouldn't it be easy to understand because there's no sail?

There's a mast for once, but there's no sail in the wind. There's just a chimney, and there's mockingbirds and smoke from it. The weather was nice, so I could see it well from afar.

... Well, there have been reports from reconnaissance planes, but that's not all. The reason they found the intended ship in the Great Fleet is because.

"What do you say, listener?

"Enemy ships are flourishing to explore the sea in sonar"

Shapeshifter listeners answered with their headphones on.

When it comes to populist things in a submarine with no windows and exploring the surrounding objects, it is sound. Explore the terrain and things from the sounds of the sea, its reflections, and so on, and go into the sea.

And it's the same for ships going on the water, making noises to explore what's going on in the ocean.

Most importantly, what the Imperial Navy is exploring in Sonar is not a submarine, but an underwater creature.

I don't know if a submarine exists in their heads, but there are large sea warcraft and so on in the oceans of this world, often attacking ships.

Though a medieval world, I can tell you that there are more clear enemies than my generation in the world where I was. Well, it's still pretty primitive.

"There's a lot of noise there, so you can count on it."

"But, Jin. Can you find out where we are?

"Phew, I hope you don't lose your Terra Fidelity skills, Mr. Bell. You can't find this ship in a primitive sonar that can't be analyzed by a superior computer."

Long live ancient mechanical civilization. Without the help of Diamante and the others, I couldn't have built a military submarine.... I think a submarine for private use would have made it if I had worked hard.

Mr. Bell said, "That's enough," so I peek into the periscope again.

"Well, your enemy's water sailing speed is slower than this one. The target is the enemy carrier. Go to the shooting point. Rudder, 10"

"Rudder 10, good luck."

SS pilots control the ship. 'Crocodile' heads to an excellent offensive position while narrowing its distance from the enemy fleet.

"Torpedo battle, ready. From the top to the fourth, induced torpedoes, loading"

A Terra Fidelitian guided torpedo is pushed into the torpedo launch tube at the bow of the ship. The onboard attack core makes fine adjustments, so even amateurs like me just instruct them to do it on their own.

The ship remains at periscope depth and targets more than the sea - target small aircraft carriers equipped with about ten aerial bods about 150 metres long.

It's small as an aircraft carrier, but it's more than twice as big as a combat sailboat, isn't it? In contrast to the surroundings, the combat sailboat is the destroyer, the cruiser is the battleship, and the small aircraft carrier looks like a large aircraft carrier.

"That's in the way of air strikes and submarines..."

"Hmm? What?

"Aviation bod. Maybe it's loaded with lightning for a nautical attack."

Even in the original world, anti-submarine tactics and so much knowledge I've read in those specialty magazines and books, but I think that kind of aviation bod is useful for submarine hunting.

I wish I could always fly to sea alert, but I guess it's the manual that Sonar finds his enemies and then sets them off.

The aviation bod itself, not a year after its birth, may be in the midst of trial and error even if it gains knowledge from people from different worlds.

Command, each ship, we're in position to attack.

Direct communications from the onboard core led to reports that each of the var-class golem submarines had been placed.

"Well, let's surprise them. Torpedoes, best to fourth, fire!

From the Crocodile class bow firing tube, 45 cm torpedoes are fired one after the other. I don't see it coming from me, but the Var-class submarines would have fired torpedoes from the launch tubes at each of the four bow gates.

If it's true, I'll just take down the periscope and dive deep, but I watched quietly for the moment to come.

And!

A giant water column rose on the side of a flat small aircraft carrier.

"Torpedoes, hits!

The audience also reported it, but I confirmed it with these eyes.

Willidis submarine lightning strike sinks enemy cruiser 3, small aircraft carrier 3. Cruiser 1, Flying Dragon Mothership 1 devastated and drove them out of navigation.

From the flaming Fei Long Mothership, he said, he saw a flame-wrapped Fei Long creeping around and submerging in the sea.

The Willidis submarine dives and turns the enemy's eyes away. Shortly before that, strike a successful attack with a lightning strike.

This report was received at the Norte Sea Fleet, as well as at the Fluff Island Command.

First and third fleets of the Great Empire where aircraft carriers sank, rendering action by air bods and flying dragons impossible. There, the fleet 'Flying Falcon' of the Norte Sea fleet fleet fleet flew in.

A total of two flying squadrons, 21 like raptors, attacked the Imperial Seafleet with a TA-3 Seafan onboard attacker and a TH-3 Seahawk onboard general purpose helicopter.

Seafang is an airplane but has a helicopter-like torso without a rotor. The collapsible main wing is called the Weapon Wing, which suspends missiles, but also has a built-in missile in the wing. Due to manoeuvre by floating stones and magic jets, the wings are more for weapons than for flight.

With combat experience in pirate hunting, the Flying Falcon crew slams a small guided bullet into an Imperial Army combat sailboat. The heavily unarmed combat sailboat was blown up its wooden hull and destroyed one after the other.
