Central calendar Year 1639, Month 4, Day 22.

Qua-Toyne Principality Government Council

Gim fell into the Louria Kingdom's hands. Furthermore, there was also a catastrophic disaster where most of its citizens were slaughtered. The Government Council was wrapped in a gloomy atmosphere of the likes it never had seen before.

"Report the current situation."

The Prime Minister Kanata ordered and so the cold-sweat-bathed Military Minister answered.

"Yes, Your Excellency… Currently, all of the land west of Gim has fallen into the Louria Kingdom's control. Even the advance force was more than 30,000 men strong, and according to information from the Intelligence Bureau, the total force will reach 500,000. Furthermore, we have unidentified information that they have received military support from the Papardia Empire, and in fact, this time they had provided 500 Wyverns. Additionally, there are reports of a fleet of over 4,000 ships departing from the port."

It was unbelievable. Everyone had their breaths taken away as they repeated that information in their heads. The figure of 500,000 men was ten times the total military force that Qua-Toyne had, even after throwing in the reserve troops. Moreover, the 500 wyverns and the sea force of over 4,000 ships.

The Louria Kingdom was seriously attempting to seize this country. And Qua-Toyne had no power at all to defend against them.

The meeting room was tucked into silence at that great despair.

At that time, the Foreign Minister raised his hand.

"Prime Minister, may I have a word?"

"...What? Is there still something else?"

Was there yet another thing else to overrun us even more than this? Kanata, who already given up, prompted the Foreign Minister to speak.

"Just before this Council meeting was started, there was a message from the Japanese embassy..."

"And the contents?"

"Yes, I will read the full text: 'We, the Imperial Government of Japan, under the direct orders of our Emperor, have decided that we cannot overlook the inhuman acts caused by the barbaric Lourian Army that occurred in Gim, a city of Qua-Toyne. We request the Qua-Toyne Government to allow a foreign intervention from the Empire of Japan, allowing the Imperial Army and Navy to be able to move freely to your lands and territorial waters. Furthermore, if the Qua-Toyne Government accept this request, then the Imperial government is prepared to dispatch 1 million soldiers, including armored vehicles, artillery, and mechanized units to Qua-Toyne to eliminate the barbaric Lourian Kingdom along with all of her armed forces.'"

"Imperial Government? Emperor? Does that mean that they're an Empire?"

"Ah, yes. But, there's another text on the next page: 'We formally apologize for deceiving you. It is our sincere goodwill that we have not shown you our status as an Empire. We believe that if we told you that we are an Empire, it would have given negative responses as seen from our first encounter in the Zuikaku from the weary sailors. As such, we have not shown you the full extent of our national and military might as we know nothing of this world and the many dangers it held. With a population of 500 million, with an active force of 6 million soldiers, and 30 million men in reserves. We believe it is time to show ourselves to this world that we, The Empire of Japan, one of the Seven Great Powers of our previous world, will raise the sun over their barbaric nation and prove ourselves as a Superpower with the Louria Kingdom itself as our stepping stone. Never shall we be hidden from this world once more, for a new era shall envelop this world. And we will make it a reality.'"

The Foreign Minister and the rest of the Government Council paled in fear of what they thought was a peaceful nation is a powerful Empire with a seemingly invincible army and a seemingly bottomless pool of manpower.

Prime Minister Kanata honestly thought that they were lucky enough to be diplomatically friendly with this Empire. Given the reports of the efficiency of the company of soldiers from Japan towards the bandits, he can roughly guess what will happen to them if the Empire of Japan were to invade both Qua-Toyne and the Quila Kingdom together.

"Aside from this... Inspiring message, do they mean to send reinforcements? Like, a million of those soldiers?"

"...Yes, they do. If we grant them freedom of movement in our land, air, and water territories, I believe that we can benefit from this as they can push back the invading Lourian Army back to her capital, annihilating them, possibly annexing core Lourian territories, create multiple vassal states from the former nations Louria conquered, and the control of half of the Rodenius Continent. As a result, we will be saved, armed with the knowledge of the extent of Japan's military, and remain independent."

Despite this new information shown to them. Peaceful dawn was rising in the abyss of despair.

The light was lit in the eyes of every Council member, as they regained their spirits. Along with simple question from the Prime Minister.

"Was that all?"

"...Yes."

"Good! Immediately send a message to the Empire of Japan that we accept their request for a foreign intervention! Please convey that we will also prepare the food for the reinforcements. Furthermore, until the elimination, and possibly the annihilation of Louria, we will grant them full control of our suppliers. Then, the Military Minister! Please inform the entire Knight Order and the Dragon Squadrons to fully cooperate with Japan!

"Yes, Your Excellency! By your command!"

Japan

"My dear loyal subjects, to those who are viewing this on television, listening to the radio, and both. This is your Emperor speaking, and I convey you all a message.

To all of you who are aware of our transfer to this world, listen! I shall reveal the truth of the cause of our transfer in this world.

Back on June 3rd, Showa 15. The day where the combined might of the Army and Navy commenced the attack on Midway and we have declared victory over the United States.

However, I will tell you this, about the disheartening truth about our declaration of victory. For it was false.

We were defeated, utterly humiliated in front of the Allies and have lost all 4 of our main Fleet Carriers that have participated in that battle. That same battle that we have significantly lost most, if not, all of our offensive capabilities in the battle over control of the Pacific. It was utterly a military disaster over that single. decisive engagement over a small island in the Pacific.

For more than two thousand and six hundred years since the founding of this great nation that we have known no defeat, that is until we have felt that single defeat that would've spiraled down the destruction of Japan should the war between us and the Allies raged on have we been in our world.

It was that defeat was the main, and perhaps, the only reason we were transported to this world.

We were transported in this world for the sole reason for us to redeem ourselves from that humiliating defeat.

For more than five and a half years have passed since we were transported in this world, we have built ourselves from the ashes of defeat and we have risen the strength of our Army and Navy, far surpassing our previous strength from our world. And our Economic status had grown exponentially over these five years.

Furthermore, we have gained a contact from a friendly nation exactly a thousand kilometers south of the Home Islands. They hail from the Rodenius Continent, half the size of Australia, and are named the Qua-Toyne Principality.

We have established diplomatic friendship and have given them economic aid for their country, alongside with another friendly nation, the Quila Kingdom.

After a month of contact, we have terrible news that both the Qua-Toyne Principality and the Quila Kingdom have been declared war by an extremely hostile nation that has controlled half of their continent, the Louria Kingdom. An expansionist nation seeking to unite all of the Rodenius Continent under their regime.

Although we are neutral in this conflict, as we have nothing to justify a small gain in this unnecessary conflict, and we have planned to stay out of this conflict. However, the Qua-Toyne Principality has pleaded and sought our intervention for their war that will decide the fate of their continent.

After initially refusing their offer, we have discovered the atrocities committed by the barbaric Lourian Army at the border town Gim, a Qua-Toynese territory.

We have decided, after much debate with the Diet, we declare war against the Louria Kingdom on the side of the Qua-Toyne Principality and the Quila Kingdom.

It is time for us to show this world what this great Empire, a once feudal nation that had quickly industrialized to combat the Western Powers that have been controlling Asia for far too long.

We have beaten enemies who were supposed to be our superiors and have failed.

The Mongols that have tried to invade our soil twice and twice were they sunk by the Divine Winds.

The Qing Dynasty, which was numerically superior to us, has been defeated in the First Sino-Japanese War.

The Russian Empire, a major Western Power and the largest nation at the time, and they were soundly defeated during the Russo-Japanese War of the beginning of the century

I declare that both the Army and Navy would do their utmost capability in ensuring the annihilation of Louria with all of her Armed Forces.

I, as your Emperor, on the 20th year of my reign, have officially declared war on the Kingdom of Louria!"

-An excerpt from "The Rise of The Empire of Japan and the establishment of the Fourth Civilized Land" on Emperor Showa's famous declaration of war on Louria.

Central calendar Year 1639, Month 4, Day 25.

Maihark Port

Finally, the information that a fleet of over 4,000 ships departing from the Louria Kingdom was conveyed and the Qua-Toyne Principality Navy's 2nd Fleet, which was based in the Maihark Port, gathered its ships.

Each ship folded their sails and prepared for the upcoming battle. The sailors inspected the ladders for raiding the enemy ships and loaded the fire arrows and the ignition oil into the ships one after another.

The wooden shields to ward arrows were placed at regular intervals on the deck, and large ballistae were deployed beside the ship.

The number of ships numbered at 50.

"What magnificent scenery."

Admiral Pancare was looking at the sea where a line of military ships lined up.

"But the enemy is a large fleet of more than 4,000 ships... How many of these will survive...?"

He revealed his honest opinion. In front of an overwhelming number, a sense of insignificance filled his heart.

"Admiral, we received a message from the Navy Headquarters."

The young officer, Bruay ran toward him and reported.

"So it comes. Read it."

"Yes, Sir! 'In the evening today, a single battleship from Japan will arrive on Maihark offshore as reinforcements. Since they will attack the Lourian Fleet before our force. During the morning of the departure, we will be sent a task force to support the battleship. And we instruct one officer to board the on the battleship as an observer officer.' ...That's all."

"...What? It's only a single ship!? Is there not an error for 10 or 100 ships?"

"There is no error."

"Do they want to do this? ...Furthermore, as an observer officer? If they only sent one ship, isn't it like saying that we are sending the observer officer to his death! How can we do something like sending an officer to what is his death sentence!"

Even though they had established diplomatic relations with Japan, except for some Foreign Affairs Officials, at this time, only a few people knew the real strength of Japan. Pancare had never seen a Japanese battleship, so this was a natural reaction.

Silence spread between the two.

"...I will go."

Bruay solemnly spoke up.

"However..."

"My swordsmanship is the highest in the Navy. So if it becomes a melee fight, my survival rate is the highest. Furthermore, Metal Dragon flew from Japan. So perhaps there is a chance of victory."

"The Metal Dragon that came from across the ocean and flew without flapping its wings. I have not seen it, perhaps it can be considered to have considerable power...? I am sorry but ...I will leave this matter to you."

"Yes, Sir!"

Central calendar Year 1639, Month 4, Day 25. Evening.

Port Maihark was in a great clamor like a madhouse.

Everyone raised their voices in wonder and admiration. The citizens living nearby, the soldiers, and the sailors altogether were gazing at the direction of the sea.

"What a huge thing!"

"Unbelievable, is that a ship?"

"Is that a mountain floating on the sea?"

There were many shouts and yells.

Bruay was also doubting his own eyes. On the offshore, there was an unbelievably large ship anchored offshore.

Just by measuring with the eye, the ship had an implausible estimated length of no less than 260m, which gave off a bizarre presence. There were talks about how when the warship Pima made contact with Japan, it boarded a 260-meter-long ship, but he thought that they were just lying to exaggerate their accomplishments. However, the reality was: 'that ship existed'. Despite being anchored far away on the offshore, it was still absurdly large in appearance and had no sails.

Eventually, something flew away from that large ship.

He had eyesight good enough that he could see that people were riding in it, so he understood that it was some kind of vehicle. On the top of the vehicle, there was something like an elongated board spinning around at high speed.

Although he previously had received a message about how he would be picked up by the other party, when Bruay saw this other way to fly in the sky that wasn't a Wyvern, he was at loss for words. As it approached, there was an unfamiliar ringing sound and a loud unnatural flapping sound that put fear into the surrounding people. Eventually, a violent wind began to blow as if it could blow away anything nearby.

When the vehicles had landed in the plaza, the wind and the sounds gradually abated. A door on the vehicle's side opened, a man appeared from it and started to move with a steady gait towards the gathered crowd.

Bruay stepped forward and the man standing in front of him saluted.

"Good day, I am Tsukasaki of the Imperial Japanese Navy's Qua-Toyne Principality Deployment Force. For this occasion, we have received an instruction to pick up an observation officer from the Qua-Toyne Principality."

Bruay replied in a hurry, while also being a bit impressed by Tsukasaki's prompt behavior. Wait, Imperial Japanese Navy?

"Nice to meet you, I am Bruay, the operations staff of the Qua-Toyne Principality Navy's 2nd Fleet. I am grateful for the current reinforcements from... The Empire of Japan."

"Umm, I believe that you had been informed in advance, but have you finished your preparations for boarding?"

"Yes. I will be in your good hands."

Bruay held his the luggage and timidly boarded the vehicle ──something that was called an autogyro, "Ka-3". There were no decorations inside the aircraft, but the seat was fluffy and comfortable to sit on.

Once again, the helicopter's engine speed accelerated and there was a strange sensation of floating. Although it was somewhat slower than a wyvern, there were no jerky vertical movements caused by flapping, and the smooth ascend of the helicopter astonished Bruay. This vehicle could fly without almost no shaking and much more comfortable than a wyvern, moreover, it could transport large numbers of people or goods.

"This is... Amazing. Just how this vehicle works, is beyond my understanding..."

While in the middle of the flight to the mother ship, he kept admiring the usefulness of the helicopter.

When the helicopter approached the carrier anchored offshore, he was overwhelmed by the size of the mother ship that was incomparable when seen from the faraway shore.

What's with this ship size1 ...Ah, I understand, if the ship is this big, then a large amount of personnel could board it, and so when it becomes a melee fight, they could capture the enemy ship one by one through overwhelming numbers. As the number of captured ships increased, the fighting power will also be quickly increased, so this one ship alone would certainly be able to deal with dozens of ships.

Using his knowledge and logic, he was trying to make sense of the battleship.

Battleship "Yamato"

Total length - 256 m

Standard displacement - 70,000 tons

Construction cost - 250,001,000 yen (1937)

It was one of the five largest battleships of the Imperial Japanese Navy that could handle the arrival and departure of two helicopters at the same time.

Bruay alighted on the ship deck, if the entire deck was flat, it was wide enough for a cavalry battle.

The floor is hard... This is... made from iron? How could it float in the sea? What kind of magic is this? A ship should be constructed from wood...

With the incomprehensible fact of an iron ship floating in the sea as the beginning, Bruay's confusion kept increasing.

As he was told by Tsukasaski, he entered the ship's interior.

...The inside... Is bright. Did they burn something? No, light magic? Is this a Magic Ship?

After being guided into the ship interior that was so wide that it felt like an illusion, Bruay arrived at the bridge and met with the captain.

This time, Bruay saluted without any delay.

"I am Bruay, the navy operations staff representative of the Qua-Toyne Principality. We are grateful for the reinforcements."

"Nice to meet you, I am this ship's captain, Yamamoto. This might be sudden, but we have already located the position of the armed insurgent ships. It's about 500 kilometers west of this location. Their speed is very slow, about 5 knots, but they are heading towards our direction. So we planned to leave tomorrow morning and issue a warning to the armed insurgents to turn back. If they don't abide, then after we fire a warning shot, we will eliminate them. So please relax inside the ship until tomorrow."

"Eliminate them... Eliminate, entirely?"

How absurd. There were only 50 Qua-Toynese ships and 1 Japanese ship. Only 51 vessels couldn't possibly confront 4,400 vessels.

"Ah, no. Of course, if the enemy turns back, or begins to surrender or escape, then we will refrain from attacking."

"That's not what I meant... Certainly, our country's fleet has prepared 50 ships. Will we perform this operation with only 51 ships? This might be rude to ask, but have you been informed of the enemies' number?"

Bruay was concerned that Japan hadn't been informed of the enemy's size.

"We have been informed of the number of these barbaric ships. We have already informed the staff that there will be no need for escorts from the Qua-Toyne Navy, so we will ensure Bruay-dono's safety. Please be at ease while performing your duties."

Bruay was surprised again. The Japanese intended to challenge a huge fleet of 4,400 ships by themselves without cooperating with the Qua-Toyne Navy.

Bruay's diary of that day

I boarded the Japanese ship safely as the Qua-Toyne Principality's citizen.

The flight until the ship was extremely comfortable, the interior of the metal ship with a size beyond the norm also had a fixed temperature. additionally, it is bright even at night. Although I should be in the middle of the sea, the swaying of the waves is inexistent. Everything is out of common sense and so, I am very astonished.

In my meeting with the captain, when he told me that they will challenge Lourian's 4,400 warships with just 1 ship, I at first thought that they were suicidal. But after I observed this ship's interior, its size, and then it's metal construction, then I understood that fire arrows or ballista wouldn't be able to damage it for sure.

On the other hand, the ship's deck is so high, so the arrows fired from that higher altitude will surely hit the enemy ships. There are fixed-installed weapons, but unlike a ballista, metal tubes were ranging from 40mm to as large 46cm. But it is highly unlikely that these weapons are portable and will be deployed when they enter battle preparations. Although for a moment, I was in despair that there was only 1 ship, there is a possibility that the enemy's attacks won't be effective against this ship. Japan seems to possess absolute confidence in the battle.

To be this nervous as an observer officer, this is the first time I've felt this way ever since I had been born.

Battleship "Yamato" – Captain's Room.

Captain Yamamoto was conversing with his XO.

"Although this is the first overseas deployment of troops after our transfer to another world, it might be a conflict as expected."

"It couldn't be helped. We can't let the Qua-Toynese people be killed, so the government made this decision. Furthermore, when I heard about the massacre in Gim city, I don't want to be chummy with the Louria Kingdom."

"The opponents don't know our power. If it is only a warning shot... then they won't turn back."

"I think so too."

Both Yamamoto and the XO didn't want to spill needless blood. There should also be some of the Louria Kingdom's soldiers who didn't want to kill people, too, just like their sentiments.

"But don't you find it strange?"

"About what...?"

"The equipment of the Louria Kingdom and Qua-Toyne are medieval-era. Well, they have dragons and wyverns and communication devices called manacoms, so they are more advanced than Earth's medieval era."

The Captains remembered the documents that the diplomats and the recon units brought back from the Louria Kingdom. When they compared the appearances depicted in the clear photographs and the remaining drawings of their documents from Earth, they couldn't get rid of a sense of discomfort no matter what.

"The ships of the Lourian Army are wooden ships like in the Kamakura period, it's not a ship-of-the-line. additionally, the information said that the total forces of this fleet are 140,000 men with the 4,400 ships, which is exactly like that decisive battle that Japan had once experienced."

The XO made a surprised expression.

"It's the Second Mongol Invasion, the Kouan Campaign, right?"

The Kouan Campaign. On 16 June 1281 AD, to conquer Japan, a large fleet was sent to Japan by the order of Kublai Khan of the Mongol empire.

The Kamakura Shogunate at that time, under the Houjou Tokimune, ordered Houjou Sanemasa as the Grand Commander to Conquer the Foreigners. He then leads the defense against the Mongols.

The Mongol Empire army gathered 140,000 soldiers in total and the number of warships used in their operations crossed 4,400, which made it the largest naval invasion fleet in history before World War 2. The Mongol fleet then attacked the northern part of Kyushu, which became the main battlefield.

After the Mongol army landed at Iki and Tsushima, they annihilated the garrison in a blink of an eye, and then landed on Shikanoshima and occupied it. Numerous land and naval battles took place around both islands, which served as a berthing point for the Mongol warships. Many people met their ends at these places.

Japan, with the lessons learned from the previous invasion (the Bun'ei Campaign), had been anticipating for the second invasion, so they erected defensive walls, where they could rain arrows down when the enemy landed. They succeed in keeping the majority of enemy troops in the ocean for about two months.

Finally, a typhoon occurred, which caused decisive amounts of damage to the Mongol army.

It was said that 84,000 men from the 141,290 numbered invasion force didn't return home alive.

"If we considered that the number of IJN personnel right now is about 1.7 million and that the population of Japan in the Kamakura era was only about 5 million, then an invasion force of 140 thousand men is a frightening one. But our ancestors endured an invasion of that size. Even though the quality of equipment, tactics, and the number of soldiers of the opponents was greater than themselves, with the power of nature on their side, they won. Honestly, I feel, uneasy about the huge size of the opponent's army, but when I closely think about it, it's not worth considering compared to our own ancestors' hardships."

The conversation between Yamamoto and the XO continued until close to lights-out time.

The next day – Early morning.

The battleship departed as scheduled.

The fleet gradually increased its speed and drew white wake trails on the ocean.

"What speed!"

Bruay continued to be astonished like he was yesterday.

"This speed has far surpassed that of our army's fastest sailing ship! However... the distance to the other ships is too far. Won't they need to be closer to create a formation?"

The ship headed west at a speed of 20 knots. About 10 hours after departure, on the other side of the flat horizontal horizon line, the Lourian Navy could be sighted.

The naval battle, which stirred the otherworld's history, the so-called "Massacre of the Rodenius Sea" in the future, was about to begin.

Lourian Kingdom Eastern Subjugation Navy – Vice-Admiral Sharkun's POV

"What a sight, so beautiful."

The beautiful sail ships traveled through the great ocean with the wind full in their sails. Their number was 4,400. A large number of sailors and landing troops were on board as they headed to Port Maihark.

As far as the eyes could see, there were only ships.

The ocean couldn't be seen. This expression wasn't just mere words.

After a preparatory phase of over six years, with the military assistance from the Papardia Empire, this large fleet was finally completed. There was no means to defend against this large fleet on the Rodenius Continent.

Perchance, they could even conquer the Papardia Empire. Or so he thought.

No. After all, Papardia Empire seems to have a weapon that can destroy an entire ship, called a "gunship"...

With his reason, he calmed down the flames of ambition which showed up for a moment. It was still dangerous to challenge the Great Country of the Third Civilized Land. He looked at the eastern sea, which he ought to conquer from now on.

...Hmm? Something is flying towards our direction.

An inorganic object shaped like an insect, came flying with a rattling noise towards the Lourian Navy. At that bizarrely shaped flying form of the object that he never seen before, slight fear sprouted up inside Sharkun's heart

Is that a wyvern? ...No, it's not. What is that thing!?

The weird object, that had a red circle painted on its white body, hovered around in the sky where no arrow could reach and then it spoke up to the fleet with a loud voice that couldn't be considered could be made by a human.

This is the Imperial Japanese Navy from the Empire of Japan. Warning to the Louria Kingdom. The location ahead is the Qua-Toynese territorial waters. Retreat now, or face total elimination. I repeat-

There seemed to be people inside that flying object. Sharkun had heard a story about how the Prime Minister had turned the diplomats of a country called Japan away and refused to deal with them, but never had heard something called. However, just by looking at that flying object, he was doubtful if Japan is a barbarian country like the politicians had said.

Some people drew their bows towards "the object", but the arrows couldn't reach at all and pitifully fell to the sea. That strange object repeated the same message and after some time had passed, turned around in the sky and left towards the eastern sky.

After a while, he could see one large island on the sea ahead.

Is there an island in this place...? Can't be, the island is moving...! No way, it's a ship?

The ship, which he mistook for a large island, cut the path of the fleet's front row's sail ship at a tremendous speed and began to travel parallel with the ship. Their distance was about 300 m.

"What is that thing...? Such a ridiculously huge ship.

Vice-Admiral Sharkun was a bit uneasy, but there was only one opponent. He had 4,400 ships at his side, so it was impossible to lose.

However, the sailors had the same uneasiness towards the strange ship as Sharkun.

Comply with our terms and you will be spared! Otherwise, we will open fire on your ships! Comply with our terms and you will be spared! Otherwise, we will open fire on your ships!

Just like the previous flying object, with a loud sound, the ship issued a warning.

Sharkun thought about what they meant by an open fire and judged that perhaps it was a means of attack before he ordered the starboard fleet to attack. The sail ships began to turn starboard and closed the distance with the battleship.

"How big..."

Since the flying object that appeared mentioned something called "The Empire of Japan", it is likely that this ship might belong to that country, who hid their national status, as well. The captain of the warship who was ordered to inflict the first attack on the foreign ship had slight anxiety in the depths of his heart.

At any rate, this was a huge fleet of over 4 thousand ships. To be given the honor as the foremost spear, there was no way he going to miss it.

"Prepare the fire arrow! Don't use the ballista yet! When the distance to the enemy ship is 200 meters, release them!"

Under the instructions of the warship captain, the crews dipped the arrow tips into the oil pot placed at the deck and ignited them with the torch. While the archers felt the heat from the flames, they drew their bows towards the enemy.

They closed the distance to the enemy ship until it reached 200 meters.

"Release!"

The fire arrows were launched at the same time from the warship and drew a parabolic arc in the air as they flew towards the enemy ship. The fire arrows that were released continuously in large quantities, pierced the outer hull of the enemy ship and burned the ship ─ ─ or was what should have happened.

The majority of the fire arrows, that were released from the warship, struck the Battleship"Yamato", giving off an intermittent sound of "Clang-clang-clang" and chipped the paint of the outer hull.

The attack didn't affect Yamato's operation capabilities at all, but it rapidly distanced itself from the fire arrow's effective range.

It instantly separated itself from the fleet before turned around and stopped at a distance of about 3 km.

"Hahahahahahaaaaaa! They ran away!"

On the deck, the sailors mocked the destroyer and let loose their jeers. Of course, their jeers wouldn't reach the enemy.

However, the captain couldn't hide his surprise at the fact that the enemy was unscathed and at how fast the enemy ship's speed was.

"The fire arrow didn't stick at all. The hull seems to be made of metal..."

How will he defeat the enemy, the ship's captain racked his brain.

Xxx

Sharkun, who was closely watching the first attack, felt an uneasiness pass by his mind.

"So they ran away. Well, no matter how big their ship is, they couldn't do anything with a single ship. However... The attack just now was not effective? Also, it's fast even though it's big. To display such speed even without any means to receive the wind, just what..."

"And just like that, they attacked despite being warned. Truly barbarians floating on small boats. Such fools that brazenly refused our terms."

The Imperial Japanese Navy had received an armed attack from the barbaric Lourians, so they decided to counterattack.

"We received an attack. Hence, we will attack the hostile and barbaric navy, the target will be the 13 surface ships at portside..."

The three triple turret Type 6 46cm Main Guns, four triple turret Type 5 15.5cm Secondary Guns, and six double turret Type 3 12.7cm Dual-Purpose Guns installed on the deck of "Yamato" rotated and pointed their muzzle at 13 separate enemy ships.

Their aim was settled.

"Subete no jou –– uchikata hajime!" (All guns –– open fire!)

The IJN Battleship "Yamato" began to fire the Louria Kingdom Navy.

The good-sighted Sharkun noticed a slight change in the enemy ship 3 km ahead.

The iron pole attached to the front of the large ship looked like it was turning towards the Louria Kingdom Navy.

"What's with those poles?"

The next moment, smoke came out from those poles.

Smoke? So it started to burn by itself?

Immediately after Sharkun wondered about that, the sailing ship that was sailing in the foremost position exploded. Parts of the exploded wood, ship parts and what looked like human remains scattered and rained down onto the deck of the surrounding allied ships as huge splashes of water erupted from the sea. Then, after a delay of several seconds, they could hear a sound like something was exploding from the direction of the enemy ship.

"!? Wh-what is happening!? Impossible? An attack by the enemy!? Ho- ...Just how did they attack from that distance?"

At this power that they never experienced before, every single crew member on the fleet viewed this scene with eyes wide open from shock.

"This is bad... But, it is fortunate that the Wyverns could reach this place. Communication officer! Request the headquarters for air support! Say that 'We are engaging the enemy's flagship!'"

Although some of the thirteen warships who were blown apart still had its keel intact, before long water rushed in through the holes and it quickly slanted and sunk together with its still surviving crew.

One of the thirteen ships that directly received the shells from that close-range shot was the ship that had attacked "Yamato" with fire arrows before and now that ship was sunk with just one attack.

"I sincerely hoped that they will be surprised by this and back off..."

Vice-Captain Unabara of "Yamato" also wanted to avoid unnecessary bloodshed just like Yamamoto. Therefore, he thought that by displaying a part of their fighting power, the enemy could understand that they couldn't win and withdraw.

He might be called a peace idiot, but he sincerely wished that the enemy will withdraw with just this one shot.

Seeing that the enemy's formation was really disarrayed and the already slow enemy ship's speed was slowed down even further, he slightly expected that his wish will come true.

"Fuh... A magic weapon of such power, but it seems that it's not able to fire repeatedly..."

When "Yamato" didn't shoot for the second time, Sharkun made such a judgment.

"Lower the fleet's speed. Together with wyvern's aviation support, we will push an attack straightaway."

Sharkun's fighting spirit was rekindled.

The Louria Kingdom. Capital Guard Knight Order. Command Headquarters.

"A manacom message from Louria Kingdom's Eastern Subjugation Navy, 'We are currently engaged with a ship that is believed to be the enemy's main fleet. The enemy ship is big and equipped with several powerful magic weapons. These weapons already sunk thirteen warships of our fleet. We request air support for a counterattack.' ...End of message."

"Well-well, so it's the enemy's flagship... Very well, dispatch the entire 250 wyverns."

Patagene's mouth tip crooked as he gave the order the manacom operator.

"Ho-... However, Sir, we had already assigned 150 wyverns to the vanguard army and since we need 100 wyverns to defend the capital, there will be no more wyverns left for the main army..."

"Are you not listening? Every wyvern. If it is the enemy's flagship, this will be a decisive battle, so we must seriously throw our weight on them. ──What? Do you think the enemy has any capabilities to reach the Capital?"

"I see, I understand. "Informing all Wyvern Squadrons. We received a communication from the Eastern Subjugation Navy at sea west from Maihark. They are engaging the enemy's main fleet. Every Knight on standby has been ordered to depart and support the navy! I repeat '"

The Dragon Knights who were waiting for their turns to shine shouted their cheers.

The 250 wyverns, which had their emergency scramble order, flew to the sky one after another.

Rodenius Continent - Northern Sea

The Battleship's Combat Information Center (CIC) had already detected "them".

"This is... Not good, if we do half-baked attacks, it might put our lives at risk."

The flying objects that appeared on the radar were numbered 250 and they could keenly feel that the enemy was not giving up at all.

They must make a swift judgment and so they decided to intercept the flying objects with full power.

"Intercept them as soon as we are ready. All hands, prepare for air combat! Don't let it become another Midway! Load all of the Main and Secondary Guns with the Modified Type 3 Shell! Including all of our AA Batteries!"

An order, that would be unthinkable back on Earth, was given to the Yamato's entire crew.

Suddenly, smoke rose one after another from the huge ship 3 km ahead. Something with tails of light passed through the skies above the Lourian Fleet. There were similar things that flew from another ship that could barely be seen on the further east direction from that huge ship, which also flew aimed in the same direction.

"What kind of trick is this!"

Sharkun was surprised but only for a brief moment, those numerous 'something' accompanied by light trails, flew from the eastern horizon with frightening speed accompanied by a thunderous roar.

He had a bad feeling about this, but he guessed that this will be gone when the wyverns arrived.

"Soon the Wyvern Dragoons from the headquarters will reach this area. All ships, attack!"

Oars protruded from the ships. Together with the sound of the drum, the oars were rowed vigorously, and the fleet accelerated.

The 4387 warship vessels of the Louria Kingdom Eastern Subjugation Navy began to attack the monster-like huge ship.

The Louria Kingdom's Dragoon Corps had departed to give naval support. This operation with 250 units, the largest one in the Kingdom's history, overwhelmed those who were on the ground and saw their gallant figures.

Aglameus, the Captain of the Dragoons, had already convinced himself of their victory.

The report from the manacom stated that it is the enemy's main force, but the Qua-Toyne Principality naval strength would be around 50 vessels at best, even if they are more powerful than this, it would be just about 100 ships at the very most.

The Navy alone was probably enough to destroy it, but perhaps Vice-Admiral Sharkun intended to keep the damage of the Kingdom's Fleet at the minimum and also showcased the tremendous number and power of the Louria Kingdom's Army and the Dragoon Corps.

This was the first time so many Wyverns were mobilized for a single combat operation, and with squadrons this big, they could able to defeat even the legendary Magic Emperor Army. There was no way that they would be stopped by something on the Qua-Toine Principality level.

Not only Aglameus, but every Dragoon also thought so.

"Hmm? What's that?"

Those with good eyesight noticed it.

"── !"

The black dots that suddenly appeared immediately shortened their distance with the Dragoons.

What are those?

In a flash, 43 densely-packed riders received direct hits from the 21 fuze shells, nine were shot by Type 6 and the rest were from the Type 5 guns. Unbelievably large flowers of fire blossomed in the air. The forward squadrons had just been instantly annihilated. The rear squadrons milled about in confusion.

"EVERYONE, SPREAD OUT!"

The moment he shouted, the Wyvern Squadrons in the middle of the flight formation were swallowed by a thunderous roar and exploding flame.

The pieces and ruined remnants of his 43 comrades fell into the sea as chunks of various sizes. Without both the still living and the already dead understood what had happened, after ten-odd seconds, another 33 Dragoons were attacked by the second wave of light arrows that exploded into rains of light. Several seconds after every Dragoons realized the situation they were into, yet another 23 Dragoons fell one after another.

Leaving a trail of light like a shooting star, those things were moving like possessing a will and obliterated the glorious Louria Kingdom's Dragoon Corps one by one. A certain Dragoon was blown without even being able to avoid, while another Dragoon who had an excellent kinetic vision took action to evade the light arrow, but he couldn't elude the exploding rain of light and perished in the explosion. Because of the extremely powerful explosion caused a flame to engulf the surrounding airspace, even if they had avoided direct hits, there were Dragoons who lost their life, engulfed by the explosion on their comrade.

"The hell!? What the hell is going on!"

Aglameus yelled.

It was something that no one could answer. Without knowing what is going on, his comrades who shared joys and sorrows, his arms brothers, and the Wyvern, which should be the strongest weapon in the world, were all but slaughtered with mechanical precision.

This sort of event never existed even as a single ink spot on the entire history chronicles.

"No way! This can't be happening!"

"I can't shake 'em! I can't shake 'em! Why? Why? I'm surrounded by the rain of lights! UWAAAAAAaaaaa-"

The manacom devices were filled with screams.

By the time the brief storm had passed away, the Wyverns had been reduced from 250 to only 75 units.

The squadrons were disordered and shaken, but finally, they could see the Louria Kingdom Navy Fleet and they reorganized their formation. When the 75 Wyverns reached the skies above the Louria Kingdom Navy, they changed into a really slow flight speed.

In front of the fleet, there was a huge gray ship.

So that's the one...?

The squadrons that had fallen into confusion before regained their composure when they saw "enemy". After they reorganized their combat readiness, they made the ship as their objective and started to accelerate again. Just then, the ship shot out light arrows in succession.

"Damn you────"

Aglameus' angry voice, which was filled with hatred echoed in the sky above the Lower Fleet.

The light arrows shot by the ship pierced through to the remaining wyverns without missing a single shot.

The Lourian sailors who seen this sight from their ship deck finally lost their fighting spirit.

Their allies in the sky... were falling like raindrops.

"Damn you...! Damn you all to hell!"

Even when their numbers were depleted one after another, Aglameus and his comrades kept approaching "Yamato".

When they reached the 7 kilometers point to "Yamato", their numbers had been diminished into just 25 wyverns.

Suddenly, the iron rod attached to the ship was firing something. One unit was pierced through by that shot and fell. The loading was much faster than they thought, furthermore, light arrows rained down from the unseen faraway place.

When their distance approached the 3 kilometers point, which was near the Lourian fleet, the storm of attack ceased.

At this time, including Aglameus, only two units remained.

"So they run out of Magic? ...I will avenge my comrade's grudge!"

Aglameus' entire body was trembling with rage. The huge formation of 250 wyverns disappeared in a blink of the eyes, only 2 units remained. It will be dissatisfying if he could not exact an act of revenge for this. It was also unforgivable of how his comrades were turned into such a miserable state. Indeed, if he returned to a country like this, there will be no doubt that he would be branded as incompetent.

"Prepare to attack!"

The wyverns rode by Aglameus and his remaining comrade spread out their wing and extended their neck. They were preparing to shot a concentrated flame shot. Their jaw opened widely as the flame ball began to mold inside their mouth.

On the CIC of the Yamato-class warship "Yamato", how the approaching large group of enemies was shot down by the ship's Main and Secondary Guns shot from the ship and the current state of affairs were displayed on the radar.

The enemy's speed was slow, but their number was tremendous, that the radar operators were tense and concentrated on their duty.

That number was rapidly reduced, even by intercepting them with the Type 3 gun's attack, and they managed to reduce them to just 2 units, but those 2 units had approached until the 2-kilometer range.

A few seconds later, the Type 5 Twin-mounted 20mm Machine Cannon operated. The self-operating Machine Cannons, controlled by the Imperial Navy's latest Fire-Control Systems, had already been configured into the anti-wyvern duty configuration and accurately aligned towards the direction of the enemy. But the Type 5 40mm Autocannons were manually controlled by the crew

─── Bmmmmmmmmmmmmmmmmm ───!

A bullet storm released by both the Type 5 20mm machine cannons and the Type 5 40mm Autocannons with 600 and 120 rounds per minute firing rate respectively sounded like a beast's groan as the firing sound was too rapid.

The hundreds flying 20 and 40mm tungsten rare-metal bullets easily pierced the wyvern's strong scale and shred their robust body like a paper. The 2 units were instantly turned into minced meat and fell into the sea as black rain.

"Argh──"

The last one... also followed them afterward.

Silence reigned above the great ocean.

"..."

Everyone couldn't believe what had happened in front of their eyes and no one let out any word.

A wyvern was something next to impossible to be defeated by ships, even for a single unit. However, just by looking at their size, there were more than 200 units ── yes, more than 200 units of the elite Wyverns fell like a rain of blood.

It was not a dream. It would be better if all of this was just a dream.

"Are we... Fighting against the legendary Mage Emperor Army...?"

In front of the overwhelming strength of the enemy, Sharkun muttered in an unhinged mental state. His hands were shaking and his feet also began to shake.

He didn't know how to say this.

However, the tragic play didn't turn a blind eye to them.

On the far side eastern horizon, vessels similar to the huge monstrous ship in front of them appeared. There were four.

Perched on their entirely gray hull was the magic weapons that had mowed down the warship.

Accompanying them were 19 vessels, 13 smaller ships carried the same poles that were seen on the port side of the monstrously large ships, and 6 were larger in comparison to those smaller ships and possessed the larger poles compared to the previous smaller ships.

Their weapons that previously eliminated warships and wyverns in the blink of the eye, turned towards Lourian Fleet and unleashed a storm of destruction.

In Rodenius history, what decides the outcome of a naval battle is a clash of sailors, which is to say, melee combat.

Although it is possible to damage the hull with ballista or ignite them with a fire arrow – though, it rarely burns – to damage the ship to a certain extent, in practice, the ship is indestructible.

Since the melee combat decided the battle, in the end, the number of sailors eventually is the deciding factor.

For the invasion this time, they had gathered 4,400 warships. It would be a different story if the opponent is the Major Powers of the Three Great Civilized Lands, but it won't be defeated by a Frontier's nation. No, with this great number, they believe they could even compete with the Major Powers of the Three Great Civilized Lands.

Or so they had, until two hours ago.

The shells fired by the arrival of 4 battleships of the Yamato-class, 2 Oyodo, and 6 Agano-class Light Cruisers, 13 Super Shimakaze-class Destroyers rapidly sunk a ship per shell. The attacks were from outside the range of their enemies. It was like a shooting exercise.

The number of roar from the main and secondary guns of the IJN Task Force was the number of how many Lourian Navy warships sunk. However, 4,400 ships were a lot.

Perhaps because of confusion or unrest, the Louria Kingdom Navy was moving chaotically. However, there was no sign of retreat, and eventually, when 4,200 ships found their rest in the watery grave amongst the seaweed, the Primary and Secondary guns' shell was nearly exhausted.

"Cease firing."

Debris of what once was ships floated on the entire sea surface.

"Myoukou" of the Super Shimakaze-class Destroyer was closing in on the enemy fleet.

When it reached the 400-meter range, it fired its three Type 5 20mm machine guns which were once used to counter an unidentified ship. An enemy ship's hull and deck were filled with holes that it slanted, the oil for the fire arrow was ignited by the torch fire and engulfed the ship with fire. Another ship sunk when its inner deck was flooded with water.

The deeds were performed businesslike and one by one, the enemy ships were sent to the bottom.

More and more, the tragedy that struck Louria Kingdom Navy continued. Eventually, the Battleships to the Destroyers had joined in with the "Myouko" in the great shooting game of turkey with their Machine and Autocannons.

Once they ran out of bullets, the "Massacre of the Rodenius Sea" was over.

With the surrounding no different from a hunting ground, the Louria Kingdom Navy fell into a panic.

"Damn it! Those monsters, we can't win against that thing! Damn it! Whoaaa!"

One ship, and then yet another ship, one by one as the time passed by, the friendly ships were sunk at an unbelievable rate.

"...So, it's futile."

Vice-Admiral Sharkun had gone beyond despair and reached the point of resignation. They can't win no matter what.

If this situation continues, it will only cause his subordinates to die for nothing. However, if they surrender and become prisoners of war, there is no chance Louria people would be spared after the massacre at Gim.

The road left open to him was only the word: retreat.

The large fleet had lost one-third of its ships. If he returned to the country, he can't escape capital punishment. His name will remain in the historical chronicles as an incompetent admiral.

But even so, he couldn't let his subordinate die more than this.

"All ships retreat! I repeat, all ships retreat!"

The retreat order was given to every ship by using the mana communicator.

Just when the flagship on which Sharkun was aboard also tried to retreat, a shell directly hit it.

His subordinate who was blown away from the explosion shockwave struck him and thrown him off to the sea.

The sight he saw while floating on the sea was the sight of his ship splitting into two and sinking.

"The enemy begins to retreat."

"All hands, cease firing!"

The order was quickly given.

"So they are abandoning their comrades that floating in the sea and retreat? ...All hands, if there are survivors in the sea, rescue them!"

The naval "battle" had ended.

Vice-Admiral Sharkun was rescued by the Imperial Japanese Navy. And there, he was given an ultimatum.

Bruay, who was aboard "Yamato", which stayed and fought since the beginning of the "battle", completely couldn't comprehend what had been going on. There was frequent exchange of words in the bridge of some sort and the next thing he knew that they were spewing out smokes and explosions throughout the fighting.

They were repeatedly shouting out coordinates, angles, shells, and so on that doesn't make any lick of sense to him. Other than this, he did personally experience the battlefield by all the shaking and the battle ended just like that with him as a spectator. Even when Louria Kingdom Fleet began to retreat, he didn't see anything, so it didn't feel real.

However, when they arrived at the sea where the battle happened for the rescue operation and he saw the sea surface in front of the ship, slowly the realization seeped in. Innumerable floating debris and countless Lourian sailors covered the sea surface. There were no burned ships. The wreckages of ship pulverized by a devastating force were floating over an unbelievable huge expanse of the sea. Amongst them, there were wyvern corpses scattered everywhere.

Although he didn't see the battle itself with his eyes, he understood that it was a complete overwhelming victory.

From Bruay's Diary Entry of that day.

I was ordered to measure how much is the power of Japan. It is the duty of a military observer officer. However, how to put this, I didn't see the battle at all. No, even the commanding admiral of the Japanese Fleet didn't personally see that battle firsthand. When we arrived at the battle location, it was already the Imperial Japanese's complete victory.

There were only the shattered ship wreckages of the Louria Kingdom Fleet, that had been blown apart by an unbelievably large amount of explosion magic projections of immense power, drifting on the sea.

Because I didn't see it, I don't know how it happened.

After the rescue operation finished, they informed me that it's a victory with 250 wyverns and 4200 warships destroyed. Even if the Japanese ship is so big, there are only 4 ships identical to this, and there were 19 others that were smaller but more agile than this so-called "Battleship", moreover, it was in a single battle. This battle outcome in this very short period was unprecedented in history.

Isn't this even impossible even for the Great Power Papardia Empire?

The crisis of my motherland had passed away, it's a truly delightful event and I ought to feel happy for it, but Japan's ── no, Imperial Japan's military power is strong beyond common sense, so I can't help but feel... Fear.

I am also greatly troubled about writing the report for the government. I must give the government a report, which wouldn't be believed by anyone, and this made my stomach hurts. There is no doubt that the same anguish also felt by the captain of warship Pima and the member of the diplomatic delegation.

We must never make enemies of The Empire of Japan. I am relieved again and again, that Japan, an Empire, which they claimed to be, who held power equal to the Great Power even in their previous world, or even more, is our allies.

At a certain warship of the Louria Kingdom Eastern Subjugation Fleet.

The Papardia Empire's military observer officer, Valhal, was trembling in his room at the warship.

This warship was luckily not sunk, but he witnessed many warships in its surrounding sunk one after another.

His duty was to record in detail how will Lourian fleet of 4,400 ships curb-stomped the Qua-Toyne Principality.

Even though primitive tactics such as fire arrows from ballista and ship raiding was fitting for barbarians, he enjoyed this mission due and personally interested in what would happen if they had these numbers.

However, the enemy ship that appeared was far beyond his common sense.

Although there was no evidence of them using "Wind God's Tear" that speed up sailships, their ship speed was overwhelmingly fast. To begin with, those ships didn't have anything that can be called a sail.

Regardless of their hull larger than the 100-Cannons Ship-of-the-Line, it had a huge... Long and slender, but that this was without any doubt, a cannon. When he saw that the ship was only equipped with three triple cannons, it greatly bothered him that he thought if this was a joke.

He was surprised that there were cannons even though the barbarian shouldn't possess one, but a cannon is not accurate. It was hard to hit things with it, hence why the 100-cannon ship-of-the-line had so many cannons. Despite that, that cannon could hit from a distance of 3 kilometers with just one shot. Moreover, it had tremendous power, that easily sunk warships with just a single hit.

What was more surprising is that they could defend against waves of wyverns attack. Even his motherland army, employed Dragon Mothership, to battle wyverns against wyverns. Because their capabilities far surpassed than the wyverns raised in the barbaric lands, if the number is equal, they would win. But the enemy this time didn't have a single wyvern at all.

In the first place, a cannon shouldn't be able to hit anything flying in the sky. This is common sense.

But they... They could even hit a wyvern with a single shot. He couldn't think this as a work of man.

If Papardia Empire did things without knowing about their existence, the Empire might even be in peril.

Using the mana communicator, Valhar reported what he had seen, as true as possible, to his home country.

The Louria Kingdom. Capital Guard Knights Order Headquarters

After receiving the information on the enemy's main fleet discovery, 250 wyverns sortied to attack it. Three hours had passed since the manacom ceased alongside with their scream.

A cumbrous silence wafted inside the headquarters.

There was no report of the meeting with any other units and even when it was the time for them to return, not a single Dragoon Knight returned. The headquarters were wrapped by uneasiness.

"Why they haven't returned?"

No one answered face-paled Patagene's question.

It can't be... They were annihilated...?

In the history of Rodenius Continent, wyverns are the strongest creature. However, since they are a valuable species, their numbers weren't that many.

The 500 wyverns of Louria Kingdom, gathered to unite Rodenius Continent was a large force finally gathered after 6 years with the military assistance from Papardia Empire.

With their overwhelming strength, they are surely able to conquer Rodenius Continent.

The 250 wyverns that sortied to support the navy would surely return and grant the greatest military result which will remain in history.

However, this was not the reality.

He didn't want to think about it. He didn't want to think about it, but there is a high possibility that they were annihilated.

Even if the enemy is an unexpectedly huge fleet, it is unthinkable that they could annihilate 250 wyverns. Can it be, does Qua-Toyne able to enlist the legendary Divine Dragon Bahamut?

In what way he should report to the Lourian King?

"...Notify the vanguard army, order 50 wyverns to return to the headquarters."

A Wannabe's Trivia of Naval Stuff:

1. Modified Yamato-class Battleships:

Armament:

3 x Type 6 Triple 46 cm Guns.

4 x Type 5 Triple 15.5 cm Guns.

6 x Type 3 Twin 12.7 cm Dual-Purpose Guns.

8 x Type 5 Single 4.0 cm AA Autocannons.

2 x Type 5 Twin 2.0 cm AA Machine Cannons.

Number of Ships: 5

Known Names: Yamato, Musashi, Shinano, Hinomoto, and Owari

Description: After the transfer and during the 5-year-long isolation period. The Yamato-class Battleships were modified based on major technological breakthroughs between the years 1942-1948.

They received state-of-the-art AA Radar and Fire-Control Systems in the years 1944- 1947 that allows the Yamato-class Battleships to accurate determine the targets' approximate location, and which angle to use on based on the calculations in the Combat Information Center.

The Fire-Control Systems were used to operate any guns ranging from 10 cm to 46 cm calibers of all types. The Type 5 20mm Machine Cannons are also accepted except for the Single-mount Type 5 40mm Autocannons.

These Battleships, alongside nearly every warship in the Imperial Navy, and were equipped with an Advanced Auto-Loading System that increases the rate of fire per minute by a factor of four. Making it highly effective on the field if any of their crew were to be knocked out or killed.

They've also come with Damage-Control Systems that will ensure that these class Battleships weren't to be sunk so easily. These systems were also installed in every warship in the Imperial Navy.

2.) Type 3 12.7 cm Dual-Purpose Guns:

Based on the performance of the Imperial Army's Type 3 12 cm AA Artillery. The Imperial Navy requested the use of the Army's AA Artillery piece and was modified to use the 12.7 cm caliber shell as a Twin-mounted Naval Gun and an AA Artillery Piece for the Navy's Use.

3.) Type 5 15.5 cm Dual-Purpose Guns:

Like the Type 3, Type 5 was based on the performance with the Imperial Army's Type 5 15 cm AA Artillery piece which was five times more effective than the Type 3 and a single piece was able to shoot down the G10N Bomber that was hijacked by rebels at 15,000 meters from sea-level.

And like the Type 3, Type 5 was modified to use the 15.5 cm caliber shell as a single, twin, and turret-mounted Naval Gun and AA Artillery Piece for the Navy's use much to the Army's chagrin.

4.) Type 6 46 cm Guns:

Based on both the Type 94 46 cm and the Type 5 15.5 cm Guns. The Imperial Navy decided to modify the existing Type 94 Gun with an improved turret with a strong traverse speed that is twice the speed of the previous gun and the effectiveness of Type 5 but with a much effective larger range.

5.) Modified Type 3 Shells:

Based on the experience the Imperial Navy faced during the Type 3s failed trials of shooting down an aircraft (courtesy of a rigged dummy) flying at maximum speed and within effective range. It was proven that time fuzes were useless on the face of fast aircraft such as the Army's Ki-84 Hayate and the recent A7M2 Reppu in late 1943.

They're also frustrated that it couldn't shoot down a high-flying bomber aircraft 15,000 meters from sea-level.

They've modified the Type 3 Shells with the introduction of Proximity Fuzes in 1944 and with an increased effective range of 16,000 meters compared to the previous model.

6.) Type 5 20mm Machine Cannon:

The twin-mount variant of the Type 2 20mm Machine Cannon.

7.) Type 5 40mm Autocannon:

Reverse-engineered captured Bofors 40mm L/60 Autocannon. Replacing the awful Type 96 25mm Autocannon.

That is all, gabrielchiong11, out!
