Bismarck

Go ask Bismarck, but he won’t say anything - are you kidding me? How can you just talk about something like that?

Even sisters have little secrets!

Only Lütjens, who knew Bismarck's "identity" well, sighed slightly in his heart.

After all, the "history" that this "Chinese tabby cat" of his own has told him is being "fulfilled" in front of him - even if the local details are different, the overall trend is exactly the same!

Although she has done her best to help her captain manage the household, and even asked her sisters to find ways to save and accumulate fuel, ammunition and accessories,

However, even if she, as the eldest sister, takes the lead in being thrifty and frugal, if Germany continues like this, she will be embarrassed sooner or later, right?

However, that is a matter of army strategy.

After all, although the industries of other countries were annexed and integrated in order to counter the true potential of the Soviet Union, the equipment was ultimately operated by people - even the ship girls needed supplies and maintenance from "fairy platelets", didn't they?

"Neither the French nor the Todt Organization are very cooperative, so I have already told Speer to transfer a batch of engineering machinery to us. Some things are more reliable if we make them ourselves..."

"Well, that's good. The empire is facing 'temporary' difficulties right now, and labor is in short supply everywhere. It's a good thing that you can save a batch of labor for us, and I will also ask other troops to learn from you and solve the problem by themselves!"

Looking at Hitler, whose face was glowing again because the situation had stabilized, and who was under pressure with his thumb and front teeth showing, Lütjens's mouth corners twitched slightly, but if you looked closely, his smile was a little awkward.

"'Live on your own'? This is really... hehe..."

The ports along the Bay of Biscay have always been the hardest hit by British heavy bombers. In addition, the French people and the forced laborers were passive and slow to work, which greatly affected the maintenance of several port facilities and warships. Lütjens, who was well aware of the contradictions between the occupying forces and the occupied people, but still had a conscience, thought about it again and again, and finally decided that it was more reliable to do the maintenance work himself.

After listening to his own ship cat talk about the things that happened in Germany during World War II, and considering that he himself was also of Jewish origin and was "witnessing" history...for some reason, he always had a kind of sympathetic mentality.

But after all, as a German general who had sworn allegiance to the country and the government, this was all he could do.

After all, 1943 was a year that seemed calm, but it was the last quiet period before the storm.

........................

Another three months passed, and it was already late May 1943, almost June.

For Bismarck, Tirpitz, Zeppelin and Prince Eugen, they basically spent their days bathing in a bathhouse called the repair shop, with the crackling sound of welding and the slight smell of acetylene.

Although the bombing continued, the location of Bordeaux Port was much farther from the British mainland. In addition, under Zeppelin's command, the GR-186 "Hellhound" carrier-based aircraft wing and the JG-2 "Richthofen" wing firmly held the air supremacy from the Brest Fortress to the Saint-Nazaire dock and then to the Bordeaux Port.

Although the current situation and resources are still tight, the modification of the Gneisenau, which has dismantled its superstructure, is progressing smoothly. Although its ability to resist attacks and severe sea conditions is a little bit difficult, the structure of the open hangar itself is still very simple. Even in order to consider jet carrier-based aircraft, it only needs to simply reinforce the angled deck, catapult and bow.

As for the modification of the Prince Eugen, which was being refitted in the temporary dock in the port of Bordeaux, it was finally completed - and in the experimental shooting, her radar and missile systems performed quite well.

Even without Eugen's own intervention, under the command of the first-generation Konrad Zuse electronic computer command system, two improved Freya search radars installed "back to back" provided the tactical situation command system and fire control radar station with a target update rate of once every fifteen seconds.

However, fire control aiming cannot be performed directly by relying solely on search radar!

Because the search radar is responsible for the airspace search of the entire battlefield, it is used to grasp the overall battlefield situation! The fire control radar can only track the target "point to point", so it must be more accurate than the search radar. Guidance and more "patient" target tracking can command the fire control radar to capture the target!

Therefore, the target discovered by the search radar is continuously tracked by another three-coordinate tracking radar (azimuth, distance, elevation/altitude) on the rear bridge, measuring the target's detailed parameters to provide a reference for the fire control radar to lock the target.

Under the guidance of the detailed parameters of the target indicated on the tracking radar display, the fire control radar operators can accurately aim the fire control radar at the direction and angle of the target in a "point-to-point" manner. Finally, after "aiming" the time gate used to measure the distance to the target, they can press the button to let the electromechanical fire control system automatically lock the target, and finally launch the missile and guide the missile to attack the target.

Monitor battlefield situation (search radar) - track and measure batches of targets (tracking radar) - lock on targets for attack (fire control radar) - track and lock on the next batch of targets after "handover". This is roughly the process of the entire system.

The principle of this fire control system was half based on the "canopy bed" system, and half was improved by Bismarck's imagination. The specific design was designed by a woman who had been in mourning for her husband for three whole months, shedding tears and gritting her teeth.

After all, Lindemann was killed by a missile "guided" by the American aircraft carrier.

She swore she would not be a human being if she didn't take revenge!

Moreover, in addition to the gnashing grapes, Eugen's performance in the experiment was also very impressive!

Unlike the technicians of the Air Force Research Institute who originally developed missile shooting, Prince Eugen, who was more accustomed to artillery ballistic attacks, commanded the missile attack mode in the exercise not in the originally designed "one shot from bottom to top", but in the same parabola as the artillery shells - first shoot the missile to an ultra-high altitude of more than 30,000 meters, and then dive down by speed and "gliding". As a result, the missile, which originally had a range of more than 30 kilometers according to the "normal mode", was directly shot down by Eugen in the hands of a Mosquito reconnaissance aircraft that was trying to come over for reconnaissance 70 kilometers away! Even the captured British pilot didn't know what happened until he entered the interrogation room and fell down.

This time, even Goering jumped up!

A missile with a range of 70 kilometers will save a lot of fighter jets for the Empire's air defense!

The air defense zone of Kammhuber's "Improved Canopy Bed" is only about 30 to 50 kilometers in radius! !

Not to mention Goering who ordered the immediate upgrade of the fire control system, even the Persian cat who had just modified the 406 main gun was envious.

Now she was even thinking about removing the rear main gun and replacing it with an anti-aircraft missile launcher or something.

The diameter of her gun mount is now 12 meters, which is much thicker than the 6.4-meter turret mount of Prince Eugen. Even if she doesn't use the complex rack structure like Prince Eugen, she can easily fit about 60 missiles by simply placing the missiles vertically and then "pulling them up" with chains in the middle of the turret.

Moreover, this structure is much simpler than Eugen's!

It turns out that a larger tonnage means greater potential for improvement~ A vain Persian cat couldn't help but feel happy.

As for the "Fat Cat" or something... well, forget it. Who wants to be a battleship? (￣﹃￣)~

only……

“I’m not satisfied with this thing!”

The cold words came out of the cold mouth of the deep sea Tirpitz, as if the cold air from the Arctic Ocean made the acceptance experts who were originally in high spirits shiver collectively at the technical acceptance meeting. And Lütjens, Bismarck, Voss, and other captains and ship girls also turned their heads one by one, looking at the cold expression of the ice queen in a daze.

What's wrong with this girl? Aren't the results of the acceptance test quite good?

But... although Tizi has always liked to stir up trouble, she is under Lindeman's "guidance", so she won't do it randomly, right?

Lütjens and Bismarck looked at each other, and then, together with the two groups of ship girls and captains on the other side who also had black question marks on their faces, they all looked at Voss with questioning eyes.

"You haven't had any conflicts recently?"

The meaning in his eyes was obvious. Voss, who was already confused, suddenly broke out in a cold sweat.

"No, no, how can that be possible."

Voss shook his head and two hands to create the effect of three rattles. Tirpitz behind him couldn't help but twitch his eyes:

After all, Voss is your captain. Why are you treating him like a thief for no reason?

"I said, Commander, sister, I just said I'm not satisfied with the fire control system, what are you doing?"

"……Eh?"

∑(°ー°〃)*N

Things soon became clear: with current technology, the architecture of this fire control system is basically like this - including the five to ten seconds of reloading and resetting time after each launch, which cannot be solved in the short term. However, four fire control radars mean that four targets can be guided and attacked at the same time each time. With a missile range of more than 70 kilometers, the air defense capability is theoretically sufficient.

However, there is only one tracking radar, which can only track one batch of targets in one direction. This is unbearable!

The Allies had absolute advantages in shipbuilding capacity and aircraft production. From the Battle of GIUK to the Battle of Biscay Bay, which time did they face opponents that did not launch crazy attacks from all directions?

Not to mention, the scene of Lindemann's death in battle, although she didn't talk about it on weekdays, but in the midnight dreams, how many times did she wet her pillow and clothes involuntarily in the memory of the little hamster crying in the dark bottom cabin of the deep sea battleship Tirpitz? ?

"This thing must be changed! I want our tracking radar to be able to quickly update target data information at all times and in all directions - even if there is a 360-degree saturation attack from all directions, we must be able to withstand it!"

The lonely queen of the deep sea of ​​the Arctic Ocean raised her cold face, and hatred and stubbornness were revealed in her blood-red pupils.

The experts who were shivering from the cold looked at each other for a while, then spread their hands in confusion, shrugged their shoulders, and shook their heads:

These experts may not know Ti Zi’s true identity, but they at least know that the person in front of them can be regarded as a great god in the current German electronics industry.

But...because of this, they couldn't figure out how to meet this request!

"Well... Miss Tirpitz, you also know that the tracking radar must keep its eyes on the target. In order to ensure the detection distance and accuracy, the radar beam must be concentrated on a single angle." An expert stepped forward and said with a bitter face while scratching his head, "So, it needs to be able to monitor continuously and monitor a wide range of 360 degrees... Such requirements cannot be met by a single radar, right?"

"If one radar can't do it, then let's get ten or eight, and place one at each angle!" The Queen of the North's tone was a little cold, especially after Lindemann's sacrifice, she was now completely dedicated to revenge and would do anything to achieve her goal.

"With small electronic tube computers now, the power generation capacity is bound to be insufficient. If it is not enough, we can dismantle a few more stupid, big, black and thick electromechanical equipment. If it is still not enough, we can replace the generator and install cables... Wait, you said that multiple tracking radars are not good for comprehensive battlefield monitoring? Then keep a low-power meter-wave radar on the rear mast as a search radar, and then put the tracking radar array and the fire control radar console together. When the search radar finds a target, it will use the tracking radar on the side to guide the missile attack! - If the current antenna array does not meet the requirements, I will make it myself (requires ultra-high inner diameter and hole opening accuracy, and the bending tube forming is very complicated) waveguide slot flat antenna array! Install one set on one side around the main mast, and add two sets of rotating mechanical backups on the rear bridge - do you have any objections?"

The edge of the gap can be used as an emitter for electromagnetic wave emission. If an antenna terminal is added to concentrate the energy, the effect will be better. As long as the design is appropriate, the energy of each transmitting port can be "synthesized into the scanning angle phase" under the diffraction effect, and it can be repeatedly scanned back and forth at a high frequency within a certain angle range. Although it has not yet achieved the legendary "phase control", with an octahedral array, it is completely possible to achieve continuous monitoring and data updates within a certain range!

The only problem is that the processing requirements for the waveguide are very precise, but... is this difficult for the KanColle?

(The flat slot antenna is used even in mobile phone base stations today, and it was first introduced around 1960.)

The lonely queen of the deep sea of ​​the Arctic Ocean spoke colder and more domineering, and the German expert group in the conference room became more and more stunned and confused. Even a German Persian cat, who was famous for his military exploits but promoted technology with his imagination, was so scared that his ears stood up straight, and what he thought of was...

Oh my god! Is my sister going to install that Aegis on everyone's head?

After picking up the eyeballs and chins on the floor, and making sure no one had left their own eyeballs behind and had to rely on the cleaning lady's broom to clean them up, the original acceptance meeting had already "derived" to the next topic...

"…There is another problem now. It is still difficult to intercept anti-ship missiles at close range. The Gatling gun we used before has a short range and cannot be manually controlled, so the effect is very limited. In this regard, we have to think of some other way…"

Colonel Voss had fully entered into the role of captain of the battleship Tirpitz and began to actively offer his opinions.

Even when he was speaking, there was some pity and emotion in Voss's eyes.

Although Tirpitz's daily relationship with him was just a nod and a hum, and the two of them didn't interfere in each other's internal affairs, he knew about the deeds of his predecessor, Lindemann, and his relationship with the Hamster minesweeper.

No matter whether it was Lindemann who was killed when the command module was penetrated by a missile, or Tizi's feeling that no matter how big a battleship is, she is still a girl, no matter from which perspective, as the second captain, he should shoulder the responsibilities that belong to the captain!

As for technology development, who doesn't know that the Evil Fleet has its own Dr. Strange Cat? Not to mention that Voss has been in office for half a year now.

"In that case..." The Persian cat rolled his eyes when asked, and an idea popped up again: "I've heard before that the Hood and Japan were both equipped with so-called anti-aircraft rocket launchers, right? Compared with missiles, the only difference is the guidance, right? Otherwise, we can also equip some, which is nothing more than installing a gas rudder on the tail?"

After hearing what Bismarck said, everyone said that they would consider it - after all, everyone has used guided artillery shells, and the difficulty of installing the guidance kit on a rocket is basically the same.

Moreover, it would be best if the things manufactured this time could allow ordinary soldiers to participate in the operation of intercepting missiles!

Although the German Navy did not have the so-called anti-aircraft rocket, it was not difficult to make. A few days later, a light rocket launcher "Himmler Organ" (caliber 80mm, maximum ground range 6000 meters, single-shot weight 6.7KG, warhead charge 0.68KG, maximum range 265*162 meters in vertical and horizontal directions, 13 launchers and 15000 rockets were manufactured, but it was eliminated after trial) was eliminated from the SS because it was considered "too low in power" (caliber 50mm, maximum ground range meters, single-shot weight KG, warhead charge KG, maximum range * meters in vertical and horizontal directions, a total of launchers and rockets were manufactured, but it was eliminated after trial), and after being equipped with a ceramic-fired gas rudder with a simple radio signal receiving device, the mm continuous anti-aircraft gun (whose range was no longer able to fight against anti-ship missile bombers) was replaced, becoming the first generation of close-range point air defense weapons that were called radio command guidance but were actually guided by the ship girl.

Germany already had command guidance, and although the specific design still needs further refinement, with Grapes here, there probably won't be any major problems.

After all, the current German fleet does not have any major combat goals for the time being.

Even though the Gneisenau had been converted into an aircraft carrier, its 230-meter length could carry sixty or seventy aircraft, and Globe had rebuilt its flying wing, but in the Atlantic Ocean right now, apart from submarines, destroyers and anti-submarine aircraft, there were currently no targets worthy of the main fleet's deployment, which would consume a lot of fuel and carry a high risk.

Speaking of which, for Germany, which is already at a disadvantage in terms of resources, if the input and results are calculated as "investment efficiency", how many can compare with submarines?

The days nowadays are obviously a bit boring, not to mention for the ship girls, even for Lütjens.

As the war progressed, Hitler, who was preparing to take advantage of the summer and autumn to fight the Soviet Union on the Eastern Front in order to restore his strength, began to exploit and plunder France more and more. Coupled with the impact of Heydrich's assassination, the German naval and air force officers and soldiers stationed in the coastal areas of France now even had no energy to go out shopping.

On the one hand, the hostility and danger are becoming more and more obvious. On the other hand, there is nothing good to buy in France now!

Whether in Germany or in the occupied areas abroad, whether it is food, clothing, or daily necessities, they have now reached the point where they have to be distributed according to tickets!

If food was still distributed in Germany based on food stamps to ensure the minimum monthly needs of personal life, in France, all Bismarck, her sisters and their captains saw were military notes issued by the so-called German Credit Bank (RKK)!

The Persian cat in her "previous life" had heard of military notes before. But now she saw them every day, and not only her, but also her sisters and the captains, were all looking at them with a headache!

The Ministry of Economy's gang was really ruthless in France, not even sparing furniture or carpets! The stolen items would be sent to a special warehouse in the name of "anti-strategic bombing reserve materials" - whether they were resold afterwards was not something that she, a German Persian cat, could know.

Come to think of it, Lütjens didn't even know about this kind of thing.

Admiral of the Navy? Golden Knight? In the eyes of some people, to put it bluntly, it's nothing!

....................................

"Wow! The wind is so strong today."

Under the bright sunshine in late May, the blonde bunny with twin ponytails stretched out one hand as if to welcome the strong sea breeze, while the other hand tightly covered the hat on her head.

"So, Eugen, are you holding your hat like this because you're afraid it'll be blown away by the wind?"

Looking at Eugen who was so silly and cute, Bismarck suddenly found it a little funny.

Eugen turned around with a (0ω0?) expression and asked: "…Yeah? What's the matter?"

"So you silly girl, you can't take off your hat?"

Little Eugen, who was covering his hat, was also ∑(°ー°〃) in an instant: "...Yeah, why didn't I think of that?"

Looking at the silly little Eugen who took off his hat and covered his face, Tirpitz, who was developing more and more like the queen of the deep sea of ​​the Arctic Ocean, said "huh" softly, took out a sketch folder from somewhere, and continued to draw something.

Now, in her daily life, even when she is doing daily training with Voss, as long as she has free time, she will sit alone in the original "hamster nest" and stare blankly, then take out a small notebook and write and draw from time to time.

However, what she drew now had turned into a professional circuit diagram, the kind that no one could understand...

"Sister Tizi, what are you planning?"

The little rabbit, who had a very good relationship with Grape, took off her hat and hugged it to her chest, dragging her neat twin ponytails and looking at the drawing board - although she had always been helping Grape sister, and the world's first ship-borne air defense missile system was installed on her. But even so, every time she saw the complicated circuit diagrams drawn by Grape sister, she felt a little dizzy.

"…long-range reconnaissance system, used for navigation and tracking of long-range anti-ship missiles."

With an absent-minded hum, the blackened hamster continued to immerse herself in her imagination. Confused, Eugen blinked and thought for a moment, then decided not to pursue (provoke) Grapes and chose to continue holding the hat without saying anything.

After all, she had studied the long-range anti-ship missile navigation course on her own, so she also knew the problems of anti-ship missile guidance.

With the search range of a few kilometers of the missile-borne radar alone, and the limitation of a fixed detection direction, the probability of missing the enemy fleet that can easily travel 30 kilometers in half an hour is very high!

Unless they can maintain continuous tracking and send guidance signals to the missiles, or can "just catch" the timing of the opponent's aircraft carrier taking off and landing, even if they are ship girls, they have to rely on luck if they want to guide missile attacks!

After all, even if it was a fleet of aircraft driven by a pilot, it could at least search over a large area. Moreover, the field of view of the fleet's sea search radar and telescope was actually wider than that of the extremely limited missile seeker!

"So, Sister Bismarck, what's the status of the plan you proposed to your superiors after the Battle of Biscay Bay, which was to equip the ship with 'ramjet-powered supersonic heavy anti-ship missiles'?"

Little Eugen, with a curious look on his face, saw that he could not get any information from his icy, homely sister, so he turned his head to Bismarck.

"I don't know. Missile development is handled by the Air Force. After all, supersonic aerodynamics is very complicated."

The Persian cat knew that he was not a science and engineering genius in his previous life. In accordance with the practice starting from the VT fuze, he clearly pushed the specific development and design work of the profession to the "real experts" from the beginning. He only provided his ideas and "impressions of ideas" and never pointed fingers at specific issues to pretend to be an expert. However, many things are indeed just lacking ideas - at least, the difficulty of developing supersonic anti-ship missiles is actually much lower than that of "Rhine Daughter" which also uses ramjet engines.
