The Z-3 computer was the first product of the Lun Group.

The Z-3 was Germany's first programmable electrical computer, and it was also a practical electrical computer, consisting of several electrical and 2600 relays, which could handle 7-digit exponential 14 decimal places, including addition, subtraction, multiplication, division, and square.

The Z-3 is input with perforated paper tape, which realizes binary number program control.

Z-3 can achieve the speed of 3~4 additions per second, or complete a multiplication operation in 3~5 seconds.

In the midst of intense research, the father of the Z-3 computer, Conrad. Chu Ze wrote the world's first computer program to play chess, becoming the first person in the world of computer programming.

Finally, the investment can be recouped, much sooner than expected.

This was Goering's first thought when he heard about the power of the Z-3 electric computer.

"Didn't you say that it would take fifty years for computers to pay for themselves on a large scale? Why now? ”

Vienna, the research office of the Lun Group, Goering asked Chen Dao in confusion.

Chen Dao said while unfamiliarly pressing back and forth on the Z-3 computer: "Fifty years later, it was a large-scale recovery cost, and now it is only a small-scale recovery, and there is no conflict between the two. ”

"Okay, that's a small problem, let's talk about the pin."

Goering casually snapped his fingers and said, "The Luftwaffe will order fifty units first, and Dr. Heisenberg's research team will book ten units first.

I also need 10 machines in my telecommunications research center to decipher codes. And then there's the Messerschmitt Wolff and Henkel aircraft manufacturing companies, they've sent engineers to try it out, and they're very happy with the performance of the Z-3, saying that it can help solve a lot of data analysis problems, such as the stability of aircraft wing jitter, a lot of complex calculations, in short, we have a wide range of applicability, and it's very popular, the only thing to worry about is the production volume. ”

"Not only them, but also the major shipyards, the ordnance bureaus of the various services, and so on. In short, all R&D departments in Germany need our products. Well, I'll take care of Marshal Raeder and Himmler, and you will get the other clients. Chen Dao said.

"For me, it's just a matter of words." Goering said confidently.

Chen Dao's gaze circled around the room. Suddenly I remembered someone.

"Where did our partners go? As the general manager, he is not in the company at such an important moment? ”

"Remcma is now in Italy, and there seems to be a breakthrough in our business with Marshal Graziani, who is going on a field trip." Goering said.

"Could it be that a big oil field has been discovered?" Chen Dao asked excitedly.

"Like, we'll know when he gets back." Goering said with a chuckle in his mouth.

Driven by interests. The money-making duo went crazy into action.

In the afternoon of the same day, Chen Dao's figure appeared in the Berlin Navy Headquarters building, and went straight to Raeder's office on the fourth floor.

Seeing that it was Admiral Rosen, the hottest in the German Navy, who came to visit, Raeder's secretary hurriedly reported to Raeder.

Chen Dao was immediately warmly welcomed by Raeder.

"Heinz, you're just in time, I'm about to send someone to find you."

"Any instructions? Commander. Chen Dao asked.

"General Lütjans has returned home, and I should hold a ceremony for you to award and promote you on next Monday."

"I'll be on time." Chen Dao said.

"You're here for an aircraft carrier?" Raeder asked.

Chen Dao hesitated for a moment, then nodded and smiled: "As the commander of naval aviation, of course I have to care about the construction of aircraft carriers. ”

A rare smile appeared on Raeder's old-fashioned face.

"Construction on the Strassel is in its final stages. It will be put into service in a month at most, but you will need to work hard to form combat effectiveness, and the modification of the Seydlitz has already begun. It's just that the design work on the Seckert-class aircraft carrier has not yet been completed, and we need more time. ”

Peter. The Strasser was the second of the Zeppelins, which began in September 1938, and after the completion of the Zeppelin, all the workers involved in the construction of the Zeppelin were transferred to the construction of the Strasser in two shifts, which made the construction of the Strasser progress by leaps and bounds, and was completed five months earlier than originally planned.

The Seydlitz was originally the fourth of the Admiral-class heavy cruisers of the Hipper. At the instigation of Chen Dao, the German Navy decided to convert it into an aircraft carrier and develop a new generation of heavy cruisers to replace it.

Chen Dao said with a smile: "Okay, there is the Strassel and the Sedlitz. Our Zeppelin is finally no longer alone. ”

After the two smiled and looked forward to the future of the German Navy, Chen Dao stated the purpose of the trip, and at the same time gave Raeder a manual for the Z-3 computer.

Raeder hurriedly flipped through the manual, and after getting a preliminary understanding of the performance of the Z-3 computer, he said with a smile: "After General Lütjans came back, he kept praising you. He said you are on the future development of the Navy. As well as the research and development of new weapons, it has a keen sense of smell, which can drive the German Navy to catch up with or even lead the trend of the development of naval equipment in the world.

His voice hasn't disappeared in my ears yet, and you have given me such a big gift, have you made an appointment? Raeder teased with a laugh.

Chen Dao hurriedly cleared up the relationship and put on a businesslike attitude.

"The Z-3 computer is definitely a game-changer and all of our R&D departments can greatly improve the efficiency of their research. We are now working on new aircraft carriers, new heavy cruisers, new submarines, and more advanced radar and sonar weapons, all of which require the assistance of the Z-3 computer.

The Air Force, the Army and the Waffen-SS, as well as the companies of Messerschmitt Krupp, are all seeking to purchase Z-3 computers, and our Navy must not be left behind, and must decide as soon as possible, otherwise it can only be received behind other services, after all, this is a new product, and the production is very low. ”

"I understand, I will notify the Navy Shipyard, William Shipyard, Blom-Forss Shipyard and the Naval Ordnance Bureau to let them send people to inspect and try, as for how much to purchase, wait for the results of the inspection to come out." Raeder said.

The next day, the chief "salesman" of the Douglas Tran Group appeared in the small town of Penemünde on the island of Utsedom in northeastern Germany.

To the east of the town of Penemünde was the German Army-led V-2 rocket research and development base, and to the west was the Luftwaffe's V-1 missile development base, but it was the SS who was responsible for guarding Penemünde.

Himmler personally accompanied Chen Dao to Penemünde to coordinate the promotion of the Z-3 computer and visit the research and development base of two epoch-making weapons.

In the technical department of the V-2 rocket, Chen Dao pointed to the V-2 rocket on the drawing and kept asking, and Dr. Braun, the director of the technical department, patiently explained to Chen Dao one by one.

V-2 is a single-stage liquid rocket with a total length of 14 meters, a weight of 13 tons, a diameter of 1.65 meters, a maximum range of 320 kilometers, an altitude of 96 kilometers, and a warhead weighing about 1 ton.

Chen Dao stared at the drawings and silently calculated whether a nuclear bomb could be stuffed with the warhead of the V-2, but unfortunately, because he was not familiar with the business but had no clue, he had to concentrate on the work of a salesman.

Chen Dao asked casually: "If I guessed correctly, when the V-2 rocket is launched, a series of data must be calculated in advance before it can be accurate, isn't that true?" ”

Dr. Braun instantly resonated with Chen's words, and he said with a wry smile: "Due to the fast flight speed of the V2 missile, a series of complex data must be carefully calculated before launch, including ballistics, flight range, and speed. All the calculations are time-consuming, cumbersome, and require multiple checks to ensure that there are no calculation errors. ”

Himmler interjected at the right time: "A research institute presided over by General Rosen has recently developed a new machine called a computer, which can assist you in performing relevant calculations and reduce your work pressure. General Rosen, can you help? ”

Chen Dao then gushed about Braun's Z-3's performance, and Braun nodded his head again and again.

"That's exactly what we need, but will it be expensive to sell for this instrument?"

"You don't need to worry about the price, the real thing to worry about is the Army Ordnance Bureau, you just need to decide whether to purchase or not." Himmler said.

In order to alleviate a lot of trouble in his research, Dr. Braun joined the SS and was awarded the rank of SS major.

Seeing Himmler's words at this time, Dr. Braun said smoothly: "I will immediately find a time to examine the computer, and if it meets the needs of the research, I will immediately report and apply for procurement." ”

After getting the V-2 institute done, Chen Dao and Himmler left Peneminde satisfied.

As for the V-1 Research Institute, it was originally a research and development base under the jurisdiction of the Luftwaffe, and there was no need to sell it, only a word from Mr. Ge.

Leaving the ship on Usedom Island, Chen Dao invited Himmler: "Are you interested in visiting the Army Ordnance Bureau with me to see our great harvest in the army's armament research and development?" ”

"What new weapons do you have?" Himmler asked.

"There are heavy tanks, self-propelled anti-aircraft guns, new anti-tank weapons, etc., there are very many types."
