Bismarck

Top shook his head vigorously, and was so scared that he was sweating coldly that he quickly shook off the scene of DIO from his mind. However, looking at Eugen who was immersed in these air force books, the frightened Top hurriedly approached:

"Eugen, what's wrong? Why are you reading these books?"

"Hey? Top, what's wrong?"

Eugen with twin ponytails raised her head and blinked her big eyes in a cute way. However, looking at Eugen like this, Top felt even more panicked:

"Nothing...wait, no...I just...why are you interested in Air Force stuff?"

"Um, this..." Eugen lowered his head a little, but soon raised it again: "Now our anti-ship missiles are about to come out, so I also want to do more for everyone!"

"How...wait! Are you saying you're studying missile tactics?"

Knowing that Bismarck and Zeppelin were guiding the scientific research team to develop cruise missiles and long-range anti-ship missiles, Top instantly guessed what his little Eugen was going to do.

After all, just think about it, the anti-ship missiles developed by several ship girls have a range of hundreds of kilometers. At this distance, they must have reconnaissance and guidance support to be able to fight!

Without reconnaissance, the missile ship is blind. And without guidance, there is no way to ensure that these missiles can bring the target into the range of the missile radar after launch - after all, the detection range of small radars in this era is less than ten kilometers.

"Yeah! Yes, yes!" Seeing that Top had guessed his thoughts with just one sentence, little Eugen, who couldn't keep things secret, instantly turned from cloudy to sunny: "Every time I see that my firepower is too poor to help, I have been thinking about how to help everyone!"

"So you thought of anti-ship missiles and anti-aircraft missiles? Do you want to be a missile cruiser?"

This ambition seems very ambitious...

Having been with the Commander and the Persian Cat for a long time, Top was certainly no stranger to ideas like missile cruisers and missile destroyers.

"Yeah! And, Top Top, I've already made an agreement with Sister Zeppelin. When she trains pilots in long-distance flight navigation, we will also go and learn long-distance sea navigation together!"

"Wow? I guess you've learned how to fly a plane!"

Hearing his own Eugen say this, Top couldn't help but laugh.

After all, as a heavy cruiser, his own Eugen had poor firepower, which had always been a concern for him!

In the Battle of Bermuda, Bismarck and Tirpitz could use guided shells to bombard British artillery from 381 kilometers away, and Zeppelin used anti-ship missiles to bombard the powerful 234 heavy artillery positions. Throughout the battle, although Eugen tried to play a greater role, the short range and low power were still the two shortcomings - it could only threaten the enemy's 152 and artillery positions, which were not very well defended, and it lost two front main guns in the counterattack of the artillery in less than ten minutes. It can be said that both sides suffered losses!

However, if it is equipped with anti-ship missiles and the oxygen torpedoes that are now being imitated...

Add to that anti-aircraft missiles... Emmmmmm...

"And I've already told Sister Bismarck and Sister Tizi about it. By the way, I seem to have heard Sister Bismarck say that there is a radar wave with a certain frequency that can detect the sea surface. Sister Tizi is currently researching it!"

(The ground wave diffraction phenomenon was actually discovered in the mid-50s, but the relevant technical difficulty is not difficult - after all, seawater containing salt is also a good conductor of electromagnetic waves. As long as an antenna with a height equal to half the wavelength is erected close to the sea surface, it will be directly equivalent to an antenna of a full wavelength under the "reflection" of the sea surface. Such a ground wave radar can detect islands, fleets and sea conditions in the distance of 200-300 kilometers, and can even detect enemy aircraft flying low over the sea! Although the accuracy is not precise enough, it is completely sufficient as a rough direction for long-range search and anti-ship missile launch!)

Speaking of this, Eugen, who was clenching her fists, was excited and blushing. She would not tell him that as the price for asking Sister Tizi to help with the research, a pile of manuscripts with all kinds of strange drawings and stapled books were now piled on top of her body. Sister Tizi also told her to keep it a secret from her two sisters.

She even secretly flipped through the paintings herself! How should I put it? Probably...

The more I think about it, the redder I get. But I don’t know why, but I always feel that doing this is somewhat exciting?

Top didn't notice the inexplicable overheating on Eugen's face, but when he heard about missile tactics and navigation, and saw his little Eugen being so motivated, Top was in a good mood, and he pinched Eugen's braids and started teasing him.

"Okay, Eugen, how about this? I'll report to the commander and ask him to dismantle your main guns and replace them with anti-ship missiles and anti-aircraft missiles!"

"Ah!? Dismantle the cannon?!"

The cooling effect of one sentence is very good. Eugen, whose boiler was overloaded and overheated for no reason before, was instantly cold when he heard the words "dismantle the gun". "No! Top, you can't dismantle my main gun!"

Seeing his own Eugen, who was so scared and pale and desperately pulling at his sleeves as if he was about to cry, Top immediately had a drop of cold sweat on his forehead. He couldn't help but think of the scene when he just became Captain Eugen and saw Bismarck and the other three sweating and fumbling around Eugen, who was crying and his hats fell to the ground.

This girl is so weak, is she really born in the Year of the Rabbit?

Besides, is it considered shit to bully our own warships like this?

On the other side, Zeppelin, who was immersed in his work at the airport, inexplicably felt that Eugen at the shipyard suddenly seemed to be in a bad mood.

Out of curiosity, I quietly reached out to take a look...

"Tsk, this Top, really..."

Spitting secretly, Qiberin withdrew his perception speechlessly and looked at the pile of documents in front of him.

"I talked to the Imperial Marshal about the development of the catapult last time. It's actually getting a bit better now? But the control of the steam valve is not easy to do. In addition, I have to consider the installation of the reserved space when I modify it myself... Forget it, I'll light the boiler and experiment with this thing myself sometime."

"Also, Captain Bangtai seems to be about to be discharged from the hospital. Should we call everyone together to arrange a welcoming ceremony for the captain?"

Looking at the things in front of him, Zeppelin fell into deep thought.

…………Top was frantically coaxing Eugen’s dividing line…………

With a series of creative ideas developed by the engineers of Bismarck and the Tank Development Committee, including stator commutation and rotor excitation and changing the excitation current to control the output characteristics and low energy consumption of the DC motor, water cooler installed at the motor outlet to control the temperature of the combat compartment occupants, automatic shell ejector, three-shot semi-automatic chain gun borrowed from the structure of anti-aircraft guns, vertical scroll springs + cast all-steel road wheels, etc., the design of the tank, which was called E-50Mogai (Magic Modification) by a Persian cat, can basically be expected to be completely solved in the short term.

However, after returning from the Führer, the captain brought back a new mission.

"Nuclear plan? What the hell is this!!"

Upon hearing that the mustache guy had assigned such a task to his captain, the Persian cat almost dropped her jaw in fright, and she was so mad that even her voice unconsciously raised an octave.

then……

“Is it necessary to be so impulsive?”*3

After the loud cat meow, except for the heartless Grape in the corner, the other three pairs of dead fish eyes all looked over in confusion.

"What do you mean by impulsive? Nuclear research and development is very complicated, okay?!"

Seeing this look, the Persian cat finally went crazy.

Although, the captain, Lindemann, and Zeppelin were all somewhat puzzled by the cat's seizure.

After all, no matter how Bismarck explained it before, and no matter whether the German military and political leaders were really interested in mushroom cultivation, the power of something like mushroom bombs still exceeded the imagination of that era.

How terrifying the power of nuclear energy is. Apart from her knowledge from later generations, I am afraid that few people know, including the man with a mustache who issued the nuclear research order this time...

Fortunately, I have been the director of scientific research at the Kaiser Wilhelm Institute for two months. Although I have not made an open investigation, I still have a general idea of ​​the situation of these scientific researchers.

After all, other people don’t know about nuclear technology, but Lily happens to know it!

And, besides that…

"Lindemann, how much have you found out about nuclear technology in the past two months?"

The captain looked at Lindemann, but it was Bismarck who was confused.

"Eh!? Captain, when did you let Lindemann investigate nuclear research!?"

"As soon as they arrived, I asked him to help me investigate. What happened?"

Hearing his secretary cat asking him this question, Lütjens felt a little puzzled.

"So, this is the reason why Lindemann has basically not gone out in the past two months?!" Bismarck was completely dumbfounded.

"What's the reason why he hasn't gone out for two months?!" Lütjens was a little puzzled.

However, this can no longer stop the lazy Persian cat from getting angry...

If I had known there would be such a good thing, I would have asked Lindman to take over this job!

How nice it is to stay at home! And you can "develop" Lily to help you investigate or something! This way you can write the investigation report without even leaving the house!

Running around in the hot summer is so hot!

and……

She would never say that she could stay at home and supervise Tirpitz closely, to prevent her from drawing on the drawing board and turning the circuit diagram and design into a book or something.

Yes, this is called preventing problems before they arise!

But now...

Looking at Lindemann, Bismarck was so unhappy that he almost rolled on the ground.

"Come on, stop interrupting me, Lindemann. Go on."

Looking at the Spartan Bismarck standing beside him, Lütjens was speechless.

"Yes, Commander... Based on what I have learned in the past two months, the situation is roughly like this. First of all, scientists don't seem to like soldiers like us interfering in scientific research..."

The Persian cat, curled up in the corner and drawing circles, always felt that he should go back and find Lily to do her work again.

Well, the father is the scientific research director who leads the nuclear research, and the daughter is a nuclear physics researcher. There is nothing wrong with this!

In the huge office, there was only a Persian cat scratching its head madly behind the sofa and Lindman reporting his work seriously.

In addition, there was a little hamster hiding in its nest in the corner, with its fur stretched out, looking at a piece of unfinished circuit board in its claws, muttering to itself:

"…It seems that we can use the layout design to print the circuit loop on both sides? Why do I always feel that… the wiring design of this circuit diagram can be drawn in an abstract style…"

"Oh yeah, there's also the ground wave radar... Tsk, why do I always feel like I have too much to do and I'm a bit annoyed..."

The big hamster, who was in a bad mood, gritted his teeth and thought that besides Lindemann, he could also get more food from the weak-looking little Eugen.

Chapter 759: Come out, Vanguard!

Lindemann spent more than two months conducting the relevant investigation, and the investigation report was very detailed.

The Persian cat hid behind the sofa with its ears tucked in, and could only accept it after listening.

However, after listening to the report, except for a certain heartless hamster, the rest of the people in the room were frowning.

After all, Germany's nuclear program is much more complicated than previously imagined.

--

As early as the late 30s, after German scientists discovered the nuclear fission effect, Abraham Eschau, president of the Imperial Physical-Technical Society, began to cooperate with the military - to be precise, the German Army Ordnance Bureau, whose directors were first "General Academician of the Academy of Sciences" Karl Becker and later Emil Leib - to establish an atomic physics research department within the Ordnance Bureau led by Dr. Dibner, and began research on the use of nuclear energy in weapons.

However, although Germany had one of the best scientific research teams in the world at that time, it was divided into several factions at this moment. They were competing for Germany's relatively limited nuclear materials for different purposes and were constantly fighting against each other.

Among these factions, the most important one and the one with the most say in nuclear research is the "Nuclear Club" composed of a large number of master-level basic physicists headed by Professor Werner Heisenberg - many of whom are even world-class masters at the Nobel Prize level.

These people controlled the distribution of most of Germany's uranium resources and heavy water by virtue of their academic influence, but their main purpose was to be more interested in basic research and nuclear energy industrialization. As for the development of weapons, no matter what the purpose was, they would delay it as long as possible. Their behavior of monopolizing a large amount of nuclear materials but "taking the funds and doing nothing" also led to the disgust of the German military and political leaders and some other "marginal" scientists.

After all, outside this "nuclear club", there are a group of unknown but young and energetic "marginal" scientists, including Dr. Schumann Diebner and Baron von Arden, who was self-taught but therefore not recognized by the "academic cliques". Under the leadership of the German Army, Navy and Air Force Armament Bureau and the Imperial Postal Department (which was the "cooperation partner" of Himmler's SS forces), they formed several groups that were contemptuously called "bombers" by the "masters" and conducted research on "new explosives with nuclear energy" and small submarine reactors.

In fact, most of these "second-rate guys" who were unknown to the public had already caught up with or even surpassed "mainstream masters" such as Heisenberg in some nuclear technology applications and design and development concepts. However, due to the dispersion of research forces and the control of vital raw materials by Heisenberg and others, both the "bomb faction" and the German high-level officials were quite unhappy about this. Especially at the end of 1941, the German military and political high-level officials, who had completely seen that there was no hope of "rapidly defeating the Soviet Union", announced to those big shots who talked nonsense all day long that "investment will be cut for any project that is delayed beyond the expected time", and at the same time separated the scientists of the "bomb faction" from the theoretical research community and organized several groups dedicated to the development and research of nuclear weapons and nuclear reactors.

Theoretically, there is no big problem in separating the basic scientific research that the "masters" are obsessed with from the weapons research and development that is urgently needed by the military and government.

but……

In June 1942, the neutron multiplication rate of the experimental reactor opened in Leipzig by scientists from the "Nuclear Club" including Heisenberg reached 6%, achieving a breakthrough in reactor neutron multiplication technology. However, an unexpected incident occurred in this experiment: hydrogen accumulated due to a leak in the reactor container, causing the laboratory's experimental records, as well as a considerable amount of uranium and heavy water, to be reduced to ashes in the flames.

Even though an accident occurred, forcing the "Nuclear Club" to move back to Berlin from Leipzig, this was the first reactor breeding experiment in history (a full six months earlier than Fermi's similar experiment in Chicago, USA). However, after this experiment, Heisenberg and others concentrated more than half of Germany's nuclear materials in their own hands on the grounds of "centralizing the use of precious nuclear materials" and were unwilling to share them with the "bomb faction" research groups - whether it was U235 or precious and scarce heavy water...

German scientists were stuck in the "heavy water cycle" and could not extricate themselves. Of course, there were scientific reasons for this. However, the superstition about the choice of heavy water reached an absurd level, which could not be attributed entirely to scientific issues. Obviously, there were also human factors. In any case, in the progress of the "uranium project", the source of heavy water was the real "bottleneck" and "weak rib", which confined Germany's reactor project to a narrow maneuvering space.

The Berlin and Leipzig experimental reactors built under Heisenberg's leadership adopted a layered structure with alternating uranium plates and heavy water layers. After the Leipzig test showed signs of neutron proliferation, he was even more determined to use his own design as a model and rejected any suggestions. Not to mention the honeycomb arrangement of nuclear fuel rods proposed by the "bomb school", he even refused to listen to other scientists in the "nuclear club"!

Bismarck was well aware that the structure of the later nuclear reactor was basically a replica of the design proposed by the "bomb faction"...

In addition, there is another thing: according to the agreement between the Army Ordnance Bureau and the Kaiser Wilhelm Association, the Physics Institute's service to the military was limited to July 42, 7. In the subsequent personnel appointments, Heisenberg and Essau served as the director of the Physics Institute and the head of German nuclear weapons research respectively. Then, in addition to the two people's research directions going in opposite directions, their personal relationship was also very bad.

In addition, Heisenberg became the director of the Institute of Physics on the premise of kicking out Dr. Schumann Dibner, the core of the "bomb faction scientists" who was the temporary head of the Institute of Physics! And this "kicking out" was actually a manifestation of a certain struggle for power: Heisenberg believed that his uranium plate-heavy water layered alternating layout structure was a perfect structure, and he could "calculate" nuclear theory research to further "add to" his scientific status. Dibner's idea was to further improve the reactor and first make a substantial breakthrough in the operation of the nuclear reactor.

As a result, when facing Dibner, who held different academic opinions from him, Heisenberg's attitude was very straightforward: relying on his academic status, he kicked Dibner out of the Institute of Physics with a simple kick!

Although Dr. Dibner himself was obsessed with the development of nuclear technology and did not care about this matter, Lindemann as an investigator and Lütjens and Bismarck as bystanders felt increasingly uncomfortable after hearing this - if it was simply a difference in academic ideas and a fight for the few remaining raw materials, then kicking someone out was nothing!

In addition to this, Heisenberg almost monopolized all heavy water and imposed strict restrictions and controls on the distribution of nuclear materials, wishing to hold all nuclear materials in his own hands. You know, at this time, Germany's uranium enrichment and heavy water production had reached a bottleneck.

Although Germany had nearly ten companies that could provide enriched uranium, and IG Farben had sufficient technology to expand the heavy water production line (in addition to the Norsk Hydroelectric Power Plant in Norway, there was actually a Leuna plant in Merseburg that could use distillation towers to refine heavy water), for some reason, these companies almost without exception refused to expand production capacity.

However, under such circumstances, the scientists of the "Bomb Group" still persevered tenaciously.

Dibner, who had been kicked out of the Institute of Physics, was concentrating on his own laboratory. With the support of the military, he was conducting his own nuclear research in his own Gettorf Laboratory with great care. Even the nuclear materials he was researching were still the small amount of stock accumulated during the previous cooperation with the military. In addition, in the absence of heavy water, he proposed the idea of ​​using graphite and paraffin as substitutes for heavy water. At the same time, the self-taught scientist Baron von Arden of the Nuclear Research Group of the Postal Ministry also invented a device called "Electromagnetic Isotope Separator" (Calutron), and claimed that with this device, Germany's nuclear raw material production could be directly increased by a large margin!

Unfortunately, apart from the military and the Postal Ministry (and Himmler behind the Postal Ministry), no one cared about any of this...

And what about Heisenberg's situation?

Although they almost monopolized most of the nuclear materials, the research at the Institute of Physics was actually very tight because suppliers were unwilling to increase production. In addition, Heisenberg had always been unwilling to improve his nuclear reactor design, resulting in low reactor efficiency, which slowed down the research progress.

In fact, someone in Heisenberg's team also proposed a design idea for a reactor that does not use heavy water: Walter Bothe, an experimental physicist who is also well-known in the German experimental physics community, suggested to Heisenberg that a "uranium-graphite reactor" could be built to replace the scarce heavy water. But Heisenberg, who "has the final say", has completely entered the academic bully mode. He even said that he would "personally decide when and how to start the construction of my Heisenberg uranium reactor!"

The final result was that Heisenberg's words made Bot afraid to speak and he quietly retreated.

Under such a clique of scholars, the research progress and potential of Heisenberg's research team can be imagined...

---

After the report was finished, the lights had already come on and a few people were still sitting in the office, discussing something.

Bismarck, who was of a straightforward nature, was the first to complain.

"Heisenberg is a great physicist, is this what he did? How could he do this?"
