The reason why it took so much time was because the enhancement that Zhang Fan needed was a permanent reinforcement, not a temporary reinforcement. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Zero's own blessing on the battleship is temporary. This is not a good thing for Zhang Fan. Before, Zhang Fan thought that Zero's enhancement was permanent, but when you upgraded to the second order, Zhang Fan knew why Zero's second order was fusion transformation, because only by using the ability of fusion transformation can the ability of the battleship be completely strengthened. At present, there is only level 1 of fusion transformation, and this level of fusion transformation can only do relatively simple transformation. Level 1 can only be optimized locally, and the time for optimization is slow. At level 2, the overall optimization and transformation can be achieved. And level 3 is the magic change! Level 3 means that as long as you have the corresponding idea in your head, you can transform it. It's just that the final effect can only depend on the results of the experiment!

The current level of zero is the second order and the first level. Therefore, Zhang Fan can only slowly transform the Prince Eugen at zero. But even such a slow retrofit shocked all German employees throughout the shipyard. They have basically come to see Zero as a true goddess. After all, a huge battleship is slowly changing itself in front of your eyes, just like a steel battleship with life. Such miraculous things can only be attributed to miracles. Therefore, during the period of battleship transformation, Zhang Fan gained a lot of willingness. These fanatical employees shouted "Valkyrie!" at the sight of Zero's presence. It's just a bunch of crazy believers!

Zhang Fan was not idle during the three-month renovation time. In order to maximize the combat effectiveness of Zero, Zhang Fan was not idle! Zhang Fan contacted Krupp in Germany and hoped to provide technical guidance.

Krupp saw that Zhang Fan was a German hero, and under the pressure of the Führer, of course, it was very cooperative.

Krupp, the head of the German Krupp company, was invited to Wilhelmshaven for an interview with Zhang Fan.

"Welcome, Mr. Krupp," Zhang Fan greeted Krupp warmly.

"Colonel Zhang Fan, I would like to express my high respect for your heroic achievements! But you also understand the habit of our Germans, you are an expert in the military, but in the military industry we are experts in the Krupp company. So I really don't know what exactly you want to talk to me about" Obviously, Krupp was dismissive of the technical discussion that Zhang Fan said!

"Mr. Krupp, please don't worry. Please take a look at this simple drawing I designed, and then say," Zhang Fan handed over a drawing drawing with a cannon to Krupp.

At first, Krupp was not very interested in this simple drawing, but after looking at it carefully, he couldn't help but be surprised: "Oh my God! This is really a genius design, which genius designed it, you must introduce it to me."

"Mr. Krupp, please calm down! This drawing is based on some of my own ideas," Zhang Fan said with some pride, although he did not know much about some high-tech weapons in later generations, but he still had some basic cognition. In a combination of the level of productivity and zero capacity during the Second World War. Zhang Fan decided to move the railgun, a big killer, to the stage in advance! After all, as an extension of the electromagnetic gun, the railgun is not only more powerful, but also has a more reasonable structure, and the difficulty of manufacturing is greatly reduced! But more importantly, the principle of the electromagnetic system is simple! For example, the anti-ship missiles and aviation missiles of later generations are the integration of the entire large scientific and technological system, which requires the combination of rocket engines, navigation systems, satellite systems, radar systems, integrated circuits, and so on. However, the electromagnetic cannon does not need it, except for the energy supply system and materials of the electromagnetic gun, there is no difficulty in the electromagnetic gun.

And the energy supply system and materials are precisely zero that can be solved. Zero, who has been promoted to the second order level, has the ability to fuse and transform, although the ability is relatively rudimentary now, and can only do partial transformation, but as long as he is willing to take the time, it is no problem to push the entire hull to start over!

"Colonel Zhang Fan, your idea is too secondary, as long as there is enough power, we can even shoot shells into outer space, which is much more powerful than the super cannon we are currently developing," Krupp said excitedly

"Super cannon?" Zhang Fan asked with interest

"Oh!" Realizing that he had slipped his mouth, Krupp immediately looked around a little nervously, and continued with a sigh of relief: "Major Zhang Fan is also his own person, but yours has to be kept secret. This is the Empire's top secret! ”

"Don't worry, Mr. Krupp, as a hero of the empire, I still know how to measure," Zhang Fan said with relief.

"Okay, I'll talk to Colonel Zhang Fan about the super cannon, and by the way, I will also listen to your opinion." Krupp actually wanted to discuss the super cannon with Colonel Zhang Fan, after all, Colonel Zhang Fan showed him such an advanced and creative artillery, and Krupp had already listed Zhang Fan as an artillery master in his heart! If Zhang Fan knew that Krupp thought like this, he would definitely be very embarrassed! After all, Zhang Fan is just a plagiarist party, just moving the weapon concept of later generations to the present, if he is really called to design weapons, it will definitely be a smear! But after all, it is to look at weapons from the perspective of later generations, and they are completely superior to the current people in terms of concept. So Zhang Fan's advice is still very referential!

As Krupp slowly planned the super cannon, Zhang Fan also knew what Krupp was talking about! This so-called super cannon is what later generations called the Gustav train cannon!

The Gustav train gun is one of the largest caliber superguns ever built.

In later generations it was named after the Krupp family "Gustav" prefix, and at the acceptance ceremony attended by the mustache himself and the quartermaster Speer, it was purchased by the military for 7 million marks, and named "Dora" after the nickname of Krupp's wife. Its barrel is 32 meters long, the total length of the gun in combat condition is 53 meters, the height is 12 meters, and the total weight is 1488 tons. Such a behemoth encountered great difficulties in assembly, transportation and firing tests. When testing ballistic performance, the loader was not yet perfect, so a crane had to be used to lift the 4-ton shell to the tail of the gun hull, and then a light tank to push it into the chamber. In order to transport the artillery to the test site, three giant transport trains with special structures were designed. The bridges along the route could not bear such a heavy weight, and the train had to go around long detours. After arriving at the position, the base was hoisted with 2 giant cranes, and then the gun carriage, gun barrel and loading mechanism were installed, and all the work was completed by more than 1,400 people under the command of a major general for 3 weeks. In order to prevent bombing by Soviet planes, antiaircraft artillery units and alert aircraft were deployed around the position, and a large number of infantry, patrolmen, and police dogs patrolled day and night within 10 kilometers around. As soon as enemy planes are detected, they are immediately covered by smoke screens by chemical troops. The total number of command, operation and guard personnel reached more than 4,000, and its shells were also appalling, each armor-piercing shell weighed 7.1 tons, a high-explosive bomb weighed 4.8 tons, and the propulsion fuel was 1.8 to 2 tons.

However, from the perspective of later generations, this super cannon is cost-effective at all, after all, its manufacturing and maintenance costs are too high to be mobile and flexible. Therefore, in later generations, there will be no country to develop this super cannon again.

At this time, Zhang Fan was already organizing some ideas in his heart, although he could not organize the outbreak of World War II, if Germany lost too badly, it would not do him any good. So he will try to try to change some of the original historical trajectories.

"Mr. Krupp, I'm actually not very optimistic about super cannons" As soon as Zhang Fan finished speaking, Krupp's face was not very good-looking. After all, anyone who says that their masterpiece is just a pile of garbage will be upset.

"I know that Krupp and the Führer have high hopes for this cannon, but I still have to pour cold water. The price, care and maintenance of such a huge gun is staggering, and its range is extremely limited. In the case of the current blitzkrieg of the German army, weapons that cannot keep up with the speed of the advance of the troops are weapons that cannot be fully effective. Hearing Zhang Fan's explanation, Krupp gradually became less resistant, after all, what Zhang Fan said was correct.

"However, when the enemy has heavy fortress artillery, our existing artillery cannot cause any damage to it at all, and at this time super artillery is needed to destroy them" Although Krupp agrees with Zhang Fan's point of view, his own super artillery can deal with some fortresses, while ordinary artillery definitely can't!
