Bismarck

Listening to his own ship cat's makeshift method, Lütjens, who was originally planning to find fault, thought again and again, but found that although this method violated the regulations, it could actually make do with this battle...

It's just... it seems too ugly, and my own big battleship is not majestic at all...

Thinking about the regulations and then thinking about the war situation, the serious and rigid traditions of the Germans and the duty of a soldier to win victory for the country, the two positions instantly turned into a little angel Lu who looked like himself and a little devil Meow with blonde cat ears, and they started fighting in Lütjens' mind without saying a word.

It was even obvious that the little devil meow with blonde hair and cat ears quickly gained the upper hand. It even seemed as if it stretched out two cat paws in front of him, made a V sign and made a face at him.

"Does this old man really want to violate the rules and regulations and ruin his reputation?"

Lütjens, who was always strict and even a bit rigid, was now completely confused.

Chapter 821: Is this a failed ground wave radar?

With one order, the entire Saint-Nazaire shipyard was quickly mobilized.

More than 7,000 sailors rushed into the shipyard, and the entire dock was immediately packed with people. The work efficiency, which was originally slow due to the lack of skilled technicians and skilled workers, increased significantly on the spot.

After all, this is a French shipyard. Even though the current French governor is Heydrich, the former chief of the Gestapo who was famous for his iron-fisted crackdown on crime and strengthening of organizational control, who knows how many ulterior motives the local workers have?

For safety reasons, up to now, these military-related things are mainly handled by people drawn from Germany.

But now Germany's human resources are also very tight...

Therefore, a unit like the Saint-Nazaire Shipyard was only allocated more than 2,000 workers.

But now, this problem has been basically solved. Because the dock can't accommodate so many people, it is now possible to implement a three-shift work arrangement!

For these sailors, maintenance of their warships is their daily work, I wonder how much they know about it!

Now, as long as the battleship's hull is repaired, the superstructure can avoid some problems - in this GIUK waterway battle, the heaviest losses were caused by the superstructure!

It would be difficult to repair it as before, but now it is easy: just install the main control computer, repair the bridge, weld the secondary gun director, and finally install two temporary radar masts and a semi-open simple navigation bridge - this requirement is really too low!

Although the appearance of the warship seems to be getting a little uglier...but the military situation is urgent and no one cares anymore.

Even Bismarck, who always loved beauty, now gritted his teeth and hardened his heart, not caring about what he "looked like".

Anyway, the worst that can happen is to demolish the chimney and the space next to the rear bridge that was originally converted into a warehouse and temporary dormitory, and convert it into anti-ship missiles and anti-aircraft gun platforms...

Oh, yes! There is also a cooling air duct around the chimney and a chimney exhaust spray condensation system! In addition, a water mist system must be added to the deck of the entire ship on the basis of the previous fire hydrant - this is the most important thing to shield the main body and isolate the infrared signal when the infrared missile attacks! Very, very important!

Standing on the balcony of the small building of the "Temporary Headquarters of the Garrison", Bismarck clenched his fists and silently reminded himself of the workers who were changing shifts under the setting sun on the seashore.

Yes! Definitely, definitely don’t forget this!

--

On a beach not far from the garrison building, the last rays of the setting sun emitted a dim red light under the sunset glow, stretching the shadows of several metal poles erected on the beach very long under the last ray of light as night was approaching.

Several wires connected to the base of the metal pole stretched to an inconspicuous small house near the small building, which looked like a farm barn. In the barn, almost buried among a pile of miscellaneous instruments and equipment, was a large pink-haired hamster and a little Eugen with golden twin tails, concentrating on the display screen of a "Hamster 511" oscilloscope. The two girls, each wearing a pair of headphones, were debugging something while holding a pen and making rustling notes of the experiment.

At least, Lindemann and Top, who were leaning against the wooden door at the barn gate, smoking and chatting, said that they couldn't understand what the two girls were doing - although the two girls told them that they were trying to develop ground wave radar or something.

Such a mysterious thing, ground wave radar? Ground wave radar? What is that?

"Come to think of it, these two girls have been messing around in this warehouse for the entire day, right?"

Top tilted his neck, blew out a long smoke ring, and looked at Lindemann opposite him helplessly.

The unspoken meaning in his eyes was obvious: My little Eugen was dragged here by your hamster for "research" for a whole day, and he couldn't be stopped even if I called him. As the captain of the hamster, you are responsible for this matter!

As for Tirpitz, even though Top knew that Eugen was very happy getting along with his sister, he couldn't help but complain.

"Don't look at me... I'm helpless too. That girl Tizi said that the ground wave radar's waveband is shortwave, which is greatly affected by the weather and day and night. There is also the difference between air echo and seawater conductive echo, so the experiment is much more complicated than expected. This time we have to do 24-hour continuous data monitoring, and write the results into a paper and send it to those research institutes... I can't do anything about her when she gets stubborn and crazy - by the way, you don't think I can drag her down, do you?"

Thinking of his hamster's serious look, which looked like "don't bother me if I have nothing to do", Lindman touched his nose and smiled bitterly.

"Tsk, stop it! It's obviously you who didn't have the heart to disturb your dog, so not only did you not say anything to her, but you also sent her food and drinks so attentively!" Top pointed at the door in a bad mood: "Send all the delicious food and drinks inside?! Look for yourself, how many bottles of drinks has your dog drunk today?"

Lindemann tilted his head slightly and saw four or five empty beverage bottles stuffed in the trash can next to the two men.

Looking at Top, who was smoking and looking unhappy, Lindman twitched the corners of his mouth and his helpless expression deepened - this was because he loved his hamster so much that he sent it in again and again along with all kinds of food.

But...

"Okay, stop laughing at me. It seems like you didn't come here to give anything to your Eugen. I have Grapes and you have Eugen. If we talk about caring about our own battleships, who cares about whom? You know~"

Lindemann turned around and raised his eyebrows at Top with a malicious and cute look on his face. That expression made him look like he deserved a beating.

"Fuck off!"

As for Lindemann's ability to kill a conversation, Tope said with a clenched fist that if your rank is higher than mine...

Although it is only natural for him to send food and drinks to Prince Eugen who is obsessed with research, you shouldn't make it sound like he deserves a beating!

He is a strict military officer and his orders are strictly enforced. Besides, how dare you say that to Lindemann, you are such a servile person who obeys Tirpitz's every command?

Knowing that the result of bickering with the monkey opposite him would most likely be that he would lose, Top, who was full of anger, glared at the monkey opposite him. He took a last deep puff of the cigarette butt, then walked to the garbage station nearby, put out the cigarette butt and threw it in, then turned around and walked back to the warehouse door, staring through the crack of the door at the blonde girl who was busy with Tizi and forgot to eat and sleep for a long time, and finally rolled his eyes at Lindeman who was smiling innocently beside him.

Lindemann shrugged his shoulders, with a business smile that looked like he deserved a beating. Seeing Top turning his head to continue looking at Eugen who was working on the experiment through the half-open door, he also turned slightly to the side, turned his head, and looked at the hamster sitting next to the instrument with her back to him under the not very bright light in the warehouse - on her head, there was a tall, pink hair that looked a little arrogant and turned a few times from time to time.

The sunset completely fell, and the night sky was filled with stars. The town was dark due to the blackout, but the stars in the sky became even more dazzling. The town was dead silent due to the night curfew. The French people, who dared not speak out, huddled behind the thick curtains at home without saying a word, secretly looking at the road outside the window with sad and resentful eyes - the uniform footsteps of the patrol boots and the occasional barking of dogs added a bit of uneasiness and weirdness to the dark night under the starry sky.

Ignoring the somewhat unsettling silence outside, the two people standing at the door said nothing, but just silently watched their hardworking girl in the dim light coming through the crack in the door.

After a long while, Top, who was still a little impatient, slowly spoke: "Lindman, what do you think will happen to us after this battle?"

"It's hard to say... But at least one thing is certain: this time the British and American navies are mobilized in full force to jointly encircle and suppress us." Lindemann answered without thinking and with an expressionless face.

Top was silent.

After all, the current strategic situation is very bad. Didn’t you see that even the lazy and gluttonous homegirl mouse in Lindeman’s house has now actively started various research and development experiments...

only……

"This time it's a joint encirclement and suppression campaign by the British and American navies, and we don't even know if the Americans have any ship girls. I always feel uneasy..." Top muttered, glancing at Lindemann beside him obscurely.

"We have to fight even if we are not sure... We are all soldiers, how can we have the final say on this matter? Anyway, we can only do our best and leave the rest to fate. As soldiers, we should be worthy of our motherland and our duties, have a clear conscience, and do our best." Lindeman tilted his head, and there seemed to be a hint of desolation and emotion in his words. But soon, someone's funny attribute broke out again. As soon as he finished speaking seriously, Lindeman turned his head and looked directly at Top, raised his eyebrows, and his originally serious expression suddenly changed to the usual wretched expression in front of Top: "At worst, I will go to see God, maybe he will give me a reward."

"?!?!" Top was stunned. What did it mean to say such an unlucky word before the battle?

"It's nothing. I just saw that you were very nervous, so I wanted you to relax a little." Lindeman smiled, showing his big white teeth that reflected 100% of the light in the night. "Besides, didn't I just say that the worst outcome is just meeting God, which is no big deal? So, don't you think about things in a positive way? Don't Americans go to meet God?"

Top, who could no longer bear it, immediately became Spartan: "Can I ask you to come to the playground to fight me one-on-one?"

"Hey, hey, hey, Top, lower your voice, don't disturb those two girls..." Seeing Top with a mad face in front of him, Lindeman immediately backed away. What he couldn't stand the most was that this guy continued to speak venomously while backing away: "I'm telling you, you can't be like this, a man should have some tolerance. I can't stand it anymore, I'll start over again."

"Get out!" Top turned around angrily, squatted aside, opened the cigarette box, and smoked his own cigarette.

After taking two puffs of smoke, Top finally let out a breath of anger.

Lindman glanced sideways at the hamster that had moved from the door to the window, but continued to pay attention to it. He opened his mouth, wanting to say something but stopped, and finally forgot what to say and could only snort angrily.

Even though he knew that Lindman was just joking with him, he was still afraid that he would not be able to help but punch that sharp-nosed monkey.

This guy really deserves a beating!

Besides, his own battleship was already obediently "controlled" by the hamster of the Lindemann family, and now he couldn't even win a quarrel with this guy Lindemann...

Hey, when will Eugen be able to show some strength and get that pink-haired girl under him?

??? What is he thinking?

He must have been so angry at Lindman that he lost his mind.

"How come I ended up with such a bad friend..."

Top, who had made the wrong friend, rolled his eyes in frustration and continued to turn his gaze towards the direction of the warehouse door.

The door opened and the blond Eugen ran out, her ponytail swinging. As soon as she walked out, she saw Top squatting by the door, smoking and looking at her.

The four eyes of the two people met each other in an instant.

"Eh?! Top!" The timid Eugen was startled by his captain squatting by the door. But he quickly reacted: "Top, the British plane is coming again!"

"What's wrong?!" After hearing this nonsensical question, Top and Lindman who was looking over were both a little confused.

Aren't these aircraft undergoing overhaul? Aren't their radars turned off?

"It's true! It came from the northwest sea at a very low altitude! Sister Grape just detected it with the ground wave radar!" Seeing his own Top in front of him with a dazed look on his face, Eugen stamped his feet anxiously and said anxiously: "...Top Top, they are only more than 170 kilometers away from here, we must hurry up and sound the alarm!"

"One hundred and seventy kilometers? Super low altitude?! This..."

Top and Lindemann looked at each other for a moment, and both of them couldn't help but show some joy on their faces.

After so many years of fighting, they were already very familiar with the way the curvature of the earth obscured radar observations. Under normal circumstances, the radar could detect this kind of ultra-low-altitude aircraft group at a distance of fifty to seventy kilometers at most! Even if the girls stayed on the main body, the maximum range of air observation was only about one hundred and fifty kilometers, right?

Now, if they can actually spot a low-flying group of aircraft at 170 kilometers...

"Eugen, has the ground wave radar experiment been successful?!" Top and Lindemann came up to him eagerly, and Top even patted Prince Eugen's shoulders, which looked rather thin and weak (in front of the battleships), with his two strong hands.

Looking at the two creatures approaching him with green eyes, Eugen was stunned: "Eh? This... no? The ground wave radar didn't work?"

"Then how did you know?" Not to mention Top, even Lindman was curious.

"Well, it was Sister Grape who asked me to call the police... The echo signal of this ground wave radar is not stable at all, and the changes are complicated. It is very troublesome to debug. Now only Sister Grape can barely distinguish the echo signal. I can't operate it, and those sailors can forget about it..." After explaining a few sentences, Eugen remembered what he was here for this time, and stamped his feet anxiously: "Top, let go first! They still have to sound the air raid alarm!"

"Uh..." Top and Linderman looked at each other, their faces flushed, and their hands loosened slightly. The next second, a little rabbit that Top had held down before lowered its body, and swooped past the two of them, disappearing in an instant.

Of the two who were staring at each other, Lindemann was the first to react: "Top, I say... why don't you ask Eugen to open the 'internal communication network' and notify Bismarck and Zeppelin? How slow is that?"

"Forehead……"

Looking at Top, who was looking awkwardly at the direction where Eugen disappeared, and even scratching his head, even a funny guy like Lindemann couldn't help but smile bitterly and opened the barn door beside him: "They have already run away... Forget it, I'll ask Tizi to go to the 'chat room' to alert the commander and Zeppelin..."

Although it seems that no one can use the ground wave radar at present - even Eugen said that she couldn't distinguish the messy echoes...

But at least it seems that even if no one can use this thing, there is at least a hamster that can use it, right?

Only Top was left, standing in front of the tall barn door, sorting out his somewhat messy thoughts in the northwest wind.

Not long after, a shrill alarm sounded over the town of Saint-Nazaire. At the airport on one side of the town, pilots and ground crew rushed out of the cafeteria, grabbing their flight gear and running towards the apron.

I had just packed my lunch and hadn’t even taken a bite when I heard the air raid sirens…

Fortunately, every time the team was withdrawn at dusk, the planes parked on the tarmac were all equipped with fuel, ammunition and radar pods in accordance with night flight standards, ready to take off at any time.

"I will lead the team this time, Grislavsky... the rest of you will come with me to seize the height and prepare for support! The remaining two veterans will lead the two newcomers, and the rest will prepare for the second wave of interception - and the newcomers, remember, if you want to be an ace, you must survive first! Remember to learn more from the seniors who lead the team after you go up! "

Zeppelin's cold voice carried a hint of annoyance due to not having had dinner, and it echoed viciously in the ears of every pilot who was on the attack.

PS: The band of ground wave radar is the same as that of shortwave radio. Radio enthusiasts know that shortwave is greatly affected by day and night (actually, it is affected by ionospheric reflection). Moreover, ground wave radar needs to rely on the conductivity of seawater for propagation, so it is greatly affected by sea waves and surface echoes. There is even a difference in the signal between sea surface echoes and air echoes (this difference can also be used for echo comparison to detect sea conditions/ships and aircraft/weather, but it requires very strong computer processing capabilities). In fact, due to the complex propagation situation, ground wave radar must frequently find a suitable frequency when using it to avoid environmental interference to the greatest extent - the specific frequency of this suitable frequency is random, and continuous detection and comparison are required to obtain a better signal/noise ratio and signal/clutter ratio, and further calculation and processing are required to obtain a target position that is only approximate (there is another set of complex signal generation and calculation processing methods to measure the distance). Due to these complexities, the so-called ground wave radar is very complicated in theory and practical operation in the entire signal generation, signal processing, computing power and other related aspects, so it is actually not so fast to use~

Chapter 822: Ugly Persian cat?

"Hey, what kind of design is this? Why does the superstructure have to be made slanted this time? Look at the lower half of the front bridge, it's made into a hexagon..."

"I don't know... I always think it's ugly. Especially the rear bridge, which is like a pyramid... Don't you think we can't even put up the scaffolding if we do this?"

"The same goes for the mast. Look at the foretop. It used to be so tall and majestic, with fire control and range finders on it. But what kind of thing is the mast now? An elongated four-sided roadblock with a radome that looks like a bean paste bun on top? It's simply the ugliest thing in the world!"

"Not only that, you guys should pay attention later. Look at the drawings she sent us. We need to leave some ventilation holes here, and then we need to connect them to the outer panel next to the chimney. How can there be ventilation in an outer panel where there is no one?"

"Look at those folded corners. To put it bluntly, they were all punched out by a stamping machine at the processing factory. They don't mind the trouble!"

"Ah... I don't know what's wrong with Secretary Bismarck to come up with this thing... Speaking of which, it's said that women love to be beautiful. Doesn't she care what she looks like by doing this?"

"Who knows, maybe she has some other intentions in doing this... Never mind, it's time to get to work. Let's weld the base of the secondary gun first - really, we have to put on that prism-like cover later, and after that, we have to polish the cover to make it smoother and then spray paint..."

"Get to work, get off work early, and go to town for a drink!"

A few disgruntled sailors took a look at the prismatic "coat" placed beside the dock, climbed up the scaffolding while cursing, and began to weld the body of their own warship.

Speaking of which, they were all completely confused by the various hexagonal hull shapes with reflectors.

And there was even some opposition in my heart.

After all, warships are the homes of sailors. Even if you are not a soldier, except for some "special people", who would like to make their home look punk, non-mainstream and weird?

The sailors could not understand the purpose of using thin iron sheets to decorate the ship into such a strange shape.

Not to mention the sailors, even Lütjens couldn't figure out what his own ship's cat was up to.

"Bismarck, is your invisible appearance really okay?"

Not to mention Lütjens, nor Bonte, Lindemann and Top, even Zeppelin and Eugen looked at Bismarck with a bit of strangeness these days.

In short, it feels like "if it doesn't work, I'll drag you out and sacrifice you to the gods."

"Oh, if I say it's okay, then it's okay! Really, I've said it so many times, invisibility and the like must have advantages! If you really don't believe it, why don't you try it with the radar after it's done? If it doesn't work, I'll just take these things off myself..."

The depressed Bismarck stamped his feet in anxiety, and made promises, swore, and vowed everything. He finally "persuaded" the captains and sisters who wanted to persuade him to stop doing anything stupid.

Although she said she was confident in her imagination - even without mentioning her "previous life" knowledge, historically Japan was able to develop a submarine command tower enclosure with an inclined angle around 1944 (for stowaway material transportation in the South Pacific Islands). So she must have anticipated the effect of doing so.
