Although Li Ran was worried, he checked the situation of their respective ship mothers before, and although the training degree did not exceed level 50, compared to this time, it should not be a big problem compared to so many ship mothers who went out together. Pen, fun, and www.biquge.info

Even at night, if there are no aircraft carriers in the battle, there may be some trouble.

Lexington watched the Admiral fall silent, and she was a little worried:

"Admiral, if only it were morning, the children would be able to support the sisters if they could attack. ”

Li Ran heard the unwillingness in Lexington's words, he thought for a while, and then said:

"It's not impossible to release carrier-based aircraft at night, but for now, forget about it for the time being, you and Gaga are working hard, by the way, what about the Raiders and Brooklyn?"

When Lexington heard Li Ran say this, she was a little incredulous, and automatically ignored the question behind it, and then looked at the Admiral with expectant eyes, and said:

"Admiral, do you have a way to make it possible for the children to attack at night?"

Li Ran thought about it, if the night vision radar is not in the game, but if the goblins' technology level can even be built to transform the core, it should be no problem to carry out the magic transformation of the ship's equipment, but this matter requires long-term planning, and although he is a marine, he doesn't know much about the principle of night vision radar, so he thought for a while:

"Well, but I don't know if it will succeed, let's not talk about this, are the raiders and Brooklyn back to the academy?"

"Yes, they went back, and the Admiral was disappointed. Saratoga said in a somewhat resentful tone.

Li Ran was choked, and he was a little embarrassed.

Lexington knocked his sister on the head, and then said:

"Don't talk nonsense, Raiders and Brooklyn have helped us a lot. ”

Li Ran was a little regretful, after all, Brooklyn was Helena's sister, she must be very happy to stay, and the raider, as a light mother, if she could also stay, the ability of anti-submarine warfare in the port area could also be greatly improved, he said helplessly:

"Go back, well, let's not talk about this for now, if they are fighting now, we can't be lazy. ”

Lexington heard Li Ran say this and was about to get up, but Li Ran's communicator flashed a hurried signal light, and Saratoga was a little curious:

"Admiral, look at the device flashing and flashing. ”

Li Ran paused for a moment, and saw the sea ear communicator he had just taken off, this was the first time he had seen the signal light flashing so quickly, he hurriedly put it on, and then after turning it on, he heard Bismarck's exclamation from the other end:

"Admiral, the big thing is not good, I am now 165 nautical miles away from the eastern coast of the port area, the coordinates are 1148 ° 51'40'' N, 112 ° 20 '09 '' E, there is a large deep-sea fleet in the eastern sea gathered and asked for reinforcements!"

"What!" Li Ran was dumbfounded, and then he forced himself to calm down and said calmly:

"You hold on first, it's really impossible to retreat to the reef area in the center of the three islands, I'll ask Helena and the others to reinforce you immediately. ”

"Understood. Bismarck nodded solemnly, then hung up the communication.

Lexington and Saratoga looked at each other, seeing that Li Ran had been deploying the battle plan after hanging up the communication, and the two did not dare to disturb.

It wasn't until Li Ran had issued all the orders that Lexington hesitated to ask.

Li Ran frowned, but it was a little strange that Lexington didn't ask, so he looked over and found the worry on their faces, and he had to force a smile:

"It's okay, it's just that there are more deep-sea fleets. ”

Lexington gritted her teeth, and then thought about it and still didn't ask the specific situation, although it was a secretary ship, but in some cases, it was not good to interfere with the judgment of the admiral, especially in the big war, and she had no experience in night battles, and she would never interfere superneously in affairs that she was not good at.

Lexington dismissed the thought, and then saw that her sister was about to ask, and she immediately interrupted:

"Gaga, go upstairs and get the proposal we've been writing these days. ”

"But ......"

"Go. ”

……

Li Ran was a little confused, but now was not the time to think about this, he saw Gaga go upstairs, and then said to Lexington:

"Help me get the scale for surveying and mapping, and the triangle plate, I want to triangulate and determine the general sea area where Bismarck and the others are fighting, since they have already fought, we must find the place where the enemy is coming, I don't believe that all four directions are the main attack points, since the eastern sea can already be confirmed to be the source of the enemy, we also have to do something for them. ”

"Admiral, you're talking about triangulation?"

"That's right, what's wrong. ”

"I didn't ...... It's nothing. Lexington sighed in his heart, he must have thought too much.

"Well, I'll take a simple measurement first, and you can help me get the tool. Li Ran didn't have time to think about it, after all, it was combat time, so he didn't think much about it, and continued to calculate Bismarck's current roughly coordinate range on the chart.

Lexington walked forward with a lot of concern, and almost bumped into his sister who came up and down the stairs.

"Sister, what's wrong with you?" Gaga hurriedly took a small step back.

"It's okay, I'll go get some tools, the Admiral must be very upset now, there are some things to talk about after the war, you know?"

"Got it, got it. Saratoga didn't talk back this time, she held a bunch of planning books, and then watched her sister hurriedly go upstairs with some worry, which was completely different from the usual calm sister, she sighed softly, and then was about to shout, but saw Li Ran leaning over the chart, holding a pencil and ruler in her hand and not drawing anything, she didn't bother with a big grin, but gently put the plan on the chair next to her.

Although he was still a little unwilling in his heart Li Ran's attitude towards his sister, but it was the Admiral, Jiajia thought about it for a while, and silently walked to the side to make a cup of coffee.

After waiting for a while, Lexington came down from downstairs with some mapping tools, and then said softly to Li Ran:

"Admiral, here you go. ”

Li Ran nodded, and then looked at these tools and looked quite professional, he was very satisfied, the more accurate the results of surveying and mapping with high-precision surveying tools can be.

Li Ran was making calculations in the area of the eastern seas, and then said without raising his head:

"By the way, how did these tools come about?"

"The Admiral still remembers the geographical expedition, right? In the afternoon, there was already a report on the prestige, in fact, the Admiral Academy headquarters behind the geographical expedition was funded and supported, and their purpose should be to calculate the newly discovered new islands in the marginal waters, so they came with our professional surveying and mapping tools. ”

"That's great, the more accurate the tool, the more accurate the results. ”

As he spoke, Li Ran took a piece of scratch paper next to him, then took a pencil and thought for a while, and began to calculate the coordinates and convert the scale.

About half an hour later, Li Ran breathed a sigh of relief, because he finally calculated the approximate range of Bismarck:

"You see, the area of the Great Triangle is the sea where they are, but this only narrows the scope, and I will ask Bismarck about it further. ”

Lexington looked at the manuscripts on the table, which were already densely filled with formulas that she couldn't understand, and some strange geometric figures, she looked at the big triangle that the Admiral had drawn with a pencil on the chart, and was stunned, how could it be calculated so quickly?

Li Ran immediately dialed the communication:

"Bismarck, where are you now? ”

"Got it. Bismarck spoke succinctly, then seemed to inquire, and after a while, then said:

"105 nautical miles from the eastern coast of the port area, the coordinates were changed to coordinates 1198°51'40''N, 152°20'09''E". ”

"Understood, you should be careful in everything, if there is no enemy, allow a tactical retreat, this first. Li Ran nodded, he could hear a few faint sounds of running from the opposite side, and knew that Bismarck and the others could not be delayed to fight now, so after noting down the coordinates, he hung up the communication, and then made the final accurate calculation.

"Their trajectory is like this, then, if you go back, the direction of the deep sea in the eastern sea should be determined to be in the northeast, by the way, ask Helena if they have found anything strange on their radar. ”

Lexington and Saratoga watched Li Ran calculate, put down their pens and ponder, and talked to themselves, they could only wait quietly, not daring to disturb, so as not to affect Li Ran's calculations.
