The entire interception sea area was determined to be a square with a side length of one hundred and fifty nautical miles.
It is not an easy task to search for a main Siren fleet in an area of more than 10,000 square nautical miles.
In fact, the Navy General Administration would like to provide accurate coordinates to the commanders, but they really can't do it. It is very rare to be able to give a vague range based on the Siren's final course and speed.
It is better to let the fleet have a search range than to let the fleet scatter aimlessly in this vast sea.
Wang Yu looked at the scope of the interception sea area, touched his chin and thought for a moment.
Most of the sea area is empty sea surface, and there are only a few islands in the eastern part of the sea area.
The islands are too scattered and not large enough to provide a combat advantage.
It seems that this battle cannot rely on the terrain, and can only confront the Sirens on the high seas.
The question now facing Wang Yu is how to find the target as quickly as possible.
As a digression here, the ship girls in this world have the function of siren early warning devices.
They have the ability to detect sirens in an attacking posture beyond visual range, but if they want to detect sirens sailing silently, the ship girls still have to get close to the minimum concealment range of the siren battleship.
Back to the topic.
In Wang Yu's view, the best way now is to let the three destroyers do their job and spread out to search for targets with maximum efficiency.
Of course, if it was before time travel, he would never dare to do this.
In the previous world, human ships without the blessing of ship girls were easily discovered by sirens. To put it bluntly, the sirens were better concealed in the silent sailing state than warships made by humans, so the initiative rested with the sirens. .
So the best way is to act as a team.
But with ship girls in this world, battleships theoretically have concealment settings similar to those of sirens.
The ship girl can even further improve her concealment through the mind chip to reduce the range of detection by the sirens.
Although depending on the warship, the concealment value brought by the ship girl is also different, and it is better or worse than the same type of ship as the Siren.
But in this way, the ability to be discovered by the siren can still be greatly reduced.
This time, the three Kagerou-class destroyers are well concealed and can conduct "stealth" reconnaissance.
This is also the reason why Wang Yu dares to spread out the fleet to conduct large-scale reconnaissance - after all, for the three destroyers, they can all discover the Siren first before they themselves are discovered.
Well, let's do it.
Wang Yu tapped the map with his knuckles, and then asked Anna to tell the three destroyer girls about her decision.
They were also highly skilled destroyers and understood the meaning of these plans. They were also familiar with Kaseren's covert reconnaissance, so after receiving the order from Anna, they immediately began to leave the side of the Annapolis and headed towards the three ships. Leave in one direction.
As night fell, the three destroyers quickly disappeared from Wang Yu's sight.
"As for us, we will continue to maintain the original course." Wang Yu said to Anna: "No matter which reconnaissance destroyer finds the target, we can immediately go to support it."
Anna nodded slightly and looked at the night outside the window: "Commander, leave the rest to me. You can go and take a rest."
Wang Yu checked the map again. The battleship had now entered the interception sea area. Although he wanted to pretend on the bridge, he also knew that he really had nothing more to do before discovering the siren.
In addition, he also knew that his flesh and blood body was incomparable to Anna.
So it is better to rest in advance and recharge for the battle that will break out in the evening.
Finally he walked to the commander's cabin below the deck.
Ana looked at his back and didn't look back until he left.
…………
Wang Yu had a dream.
He dreamed that he was sitting in a pure black space.
There was no light around him, and the environment was so dark that he couldn't even see his own body, as if he had suddenly gone blind.
But even so, he always felt like someone was peering at him in the boundless darkness.
It's the feeling of having an eye behind you that is always staring at you.
Maybe no one was spying on him, it was just an illusion in Wang Yu's dream.
But this feeling of peeping, whether it was an illusion or real, made Wang Yu extremely uncomfortable.
At the same time, walking in this black space, he also felt extremely depressed.
He wants to get out of this place.
Perhaps this psychological suggestion had an effect, and he suddenly found that the black sky suddenly became brighter...
Then he woke up from his dream.
Or to use more accurate language, he was forced to wake up.
Before he could complain about this strange dream, he noticed Anna standing beside his bed, gently shaking his shoulders.
Seeing her commander open her eyes, she said, "Miss Lan, who is in charge of the investigation, discovered the Siren."
Although his brain would inevitably be slow to react just after he woke up, the word "Siren" was enough to wake him up.
He didn't even bother to care about the dream just now, just treat it as a nightmare.
Wang Yu immediately rubbed his face hard twice, then stood up, grabbed the coat hanging on the bedside and put it on himself.
He knew what the scene was like now. He only took off his coat and shoes when sleeping, so he was sleeping fully clothed.
Then he sped through the open hatch, Anna following closely behind him.
The two of them—to be precise, one person and one shipgirl—returned to the bridge.
He glanced at his watch and found that he should have slept for about three hours, and it was almost midnight.
Well, a simple sleep should be enough to keep me refreshed for a whole night.
Wang Yu looked at the sea. It was dark outside and the weather was not very good. The moonlight was hidden behind the clouds, making the visual visibility even worse.
Naturally, he could not see any enemy ships.
Nonsense, it was the Siren discovered by the Arashi destroyer after all. The destroyer is now estimated to be some distance away from Annapolis.
Within a certain distance, ship girls have the ability to "spiritually communicate" with each other. This ability will not be interfered by sirens, so it is very effective when fighting sirens. It is better to be disturbed at every turn. The radio is much stronger.
"Where is Lan?" Wang Yu asked, looking at the map.
Anna's slender fingers accurately pointed out the positions of herself and Lan on the map, and explained: "Miss Lan left towards our port side before, and the current distance from us is about forty nautical miles in a straight line."
Wang Yu looked at the map. Lan's current position was about thirty degrees east-south of Annapolis.
"Where is the siren location and enemy situation she reported?"
"About ten minutes ago, she discovered a Siren destroyer, and then slowly approached the Siren destroyer while ensuring that she would not be discovered. Then she discovered another destroyer and a Siren heavy cruiser. .”
The stealth value of the silently sailing Siren Cruiser is about fifteen nautical miles, which is almost the same as the visual range.
Therefore, it is entirely possible that Lan first discovered the Siren destroyer that was relatively close to her, and then discovered the Siren heavy cruiser that was farther away but had poor concealment.
Anna's words were quite clear. Wang Yu could already imagine the small destroyer slowly moving toward the Siren fleet with its concealment value under the Siren's eyes, and then discovered more targets.
"Did Lan say this was our goal?"
"She said she couldn't go any further because she might be discovered by the sirens if she went any further."
When Wang Yu heard this, he couldn't help but frown.
This is a bit troublesome.
In this interception sea area, there are not only the main sirens that are targeted, but also those free sirens that may exist. Currently, among the types of siren ships Lan has observed, there are no battleships that can be conclusive, so there are still two types. All outcomes are possible.
Wang Yu tapped his fingers rhythmically on the map on the desktop. This was his habit when thinking.
So, does Annapolis need to turn?
