The naval guns roared.

Gun smoke and war covered the entire sea.

It turns out that a naval firepower conflict broke out in the world is a major event.

But in the Blue Star world, especially in border guards like Avalon, war may break out at any time.

Marina had just finished a battle with the Deep Sea Fleet and personally sent three deep-sea warships close to the capital of Avalon to the bottom of the sea.

Strong firepower.

Thick armor protection.

It also has a superman's first-class range advantage.

After one battle, Masana was hit by the enemy with only 3 shells, which was not considered damaged.

He was completely unaware of the shells flying from the sky, whether it was a close-range flat or a long-range curved cross-border.

Both Ari and Marina use a comprehensive protective armor layout.

The Gemini ship girls once asked about the True Nai.

Because comprehensive protection in the memory of ship girls proved to be backward and unreasonable.

Comprehensive protection and key protection are the design concepts of the two eras before and after the armor layout of the naval battleship.

As they literally mean.

Comprehensive protection can be explained as an even distribution of armor to wrap the entire hull.

The key protection is to thicken the armor in key areas, reduce the armor in non-key areas or even do not arrange armor at all.

On the surface, it seems that comprehensive protection is more appropriate than key protection.

But after all, times are different.

In those days, countries strictly limited the total tonnage of warships in each country for the so-called naval treaty, and also limited the displacement of various types of warships.

In the era when naval warships were getting bigger and bigger, how to form the strongest combat power under the limited drainage tonnage became the focus.

Moreover, in order to deal with the increasingly larger caliber naval guns in various countries, the key protection is indeed more effective than comprehensive protection.

But there are also those who are unique and follow the old path of the times.

This is the case with the two sisters of the Battleship Bismarck and the Battleship Tilbiz.

When the whole world was focusing on key protection, the two sisters used comprehensive protective armor, which made Bismarck known as the most survivable battleship at that time.

There is actually a reason why the sisters from Beizhai took this path.

Like the docks in those days, Bismarck and Tilbiz announced fake tonnage before the construction was completed.

The dock said that it had only 50,000 tons of water displacement, while the Bismarck sisters said that it had only 40,000 tons.

Then after coming out, all three of them had more than 10,000 tons of drainage than the ones claimed.

In fact, this is a violation.

But at that time, similar things were somewhat inconsistent and unspeakable in various countries.

With a large displacement, the Bismarck sisters chose to strengthen their armor due to the national conditions they were in at that time.

The same goes for Avalon.

The Blue Star has no naval treaty that restricts doctrines.

The extent to which the admirals can transform the ship girl into depends entirely on the sudden interest of the fairies.

In this case, Koji of course chose a comprehensive protective armor layout that seems to be relatively old but more appropriate.

The battles over the past two years have also proved that before having the advantages of drainage tonnage and the powerful performance of the new alloy formula, the performance of comprehensive protective armor far exceeds that of key protection.

Ari and Marina were hit by enemy shells more than once, and those with key parts were more important than others.

If it were other ship ladies, they would need to repair them after each battle.

Ari and Marina don't need it.

Comprehensive protective armor makes the two sisters' hull defense almost equal.

There is little difference between the key parts that hit them or not. They either directly blast the shells or cannot penetrate the armor.

The shells that cannot penetrate the target armor usually have two results. One is to knock one's head flat, and the other is more common.

The shell hits the target armor at high speed but cannot cause breakdown, so it can only leave abrasions on the target armor and bounce it away in other directions.

On the battlefield:

The shells whistled and hit the target.

After a bang, it was bounced to somewhere unknown.

Both Ari and the Marina sisters have encountered this kind of attack many times.

The super-high armor brings the capital to Avalon's two sisters to face the advanced deep-sea warships at a low level.

Looking at how many ship girls in other garrisons can guard the sea and border alone with few enemies, they can go on a complete battle and return to the port in a complete battle.

Proficiently travel through the fog of war outside Avalon.

Masana, who returned to the port, did not go to compete for the position with the Shalena guardian fleet in Port 1.

The development of the Avalon II port has entered the semi-finished stage, unlike in the past, it still retains its original natural appearance.

Instead, a series of warship berths were built. After the hull with a displacement of nearly 50,000 tons entered the special channel trough, a large number of unmanned equipment controlled by Artoria sent her to the inner harbor.

A 50,000-ton super ship slowly disappeared on the water.

This scene made many ship girls guarding the palace talk nonsense after seeing it.

Indoor ports in the Blue Star World are not uncommon, and many admirals specially hollowed out the harbor on the side of the ward to build a sci-fi port.

But those ports either had natural foundations or were built little by little by little by decades. After completion, there was still a threat of mountain collapse and were not accepted by most people.

Let’s not talk about whether Avalon has so much time.

There is no sign of this small island of Pentagram that has a huge mouth under it.

They can't imagine what an underwater base is. As long as there is a need, Koji can build various living spaces in the Avalon underwater location at any time.

Based on personal experience, the Kaga aircraft carrier girl in Shalena's guarding the palace found a pedestrian exit at the port of Avalon II.

There were no guards guarding the door.

But Kaga was stunned when he walked to the door?

After looking around, he didn't look dangerous. Kaga carefully stretched out his hand and pushed it, but he couldn't push it, and he pulled it again, but he couldn't pull it.

It should be a door, but after thinking about it for a while, Teacher Kaga still couldn't find a way to open it.

Knock?

It is obviously a very thick iron door.

Knock on Kaz again~ the aerodynamic sound of the hatch opening.

"Uh..." Kaga and the small figure exposed inside the door were right.

Kaga has met Ali-chan of Avalon several times, and it was the first time he met Ali-my sister Marina.

Teacher Kaga sometimes wondered why the admiral gave them a distinctly neon name, two Italian ship girls in Avalon.

Say that the admiral likes the R-type ship girl?

Not very similar.

Avalon also has only five neon destroyer little guys.

"Is there anything you have?" Ba blinked his big eyes, and Marina asked kindly:

"Marina saw that you had been here for a long time before she came here to open the door for you. Are you lost?"

get lost?

Kaga is slightly embarrassed.

"I remember your name is Marina."

"Yeah, Marina is the Andrea-class No. 2 ship, and her sister is Ari."

"I saw you just now, your hull...it doesn't seem to be docked in the harbor, I'm a little curious."

"Do you want to see? Marina can take you in."

"It's not Avalon's secret, right?"

"No, Commander Shalena is in the port now, and Marina can take you to find her."

Hearing that his admiral was also inside Kaga, he was relieved.

If Marina just told her that this was a confidential area, Kaga would cooperate and return.

Marina was not alone and there was a small car behind Loli with a strange shape that was as petite and cute as hers.
