"Hannah, call you the V2 rocket research team that you once participated in the test flight." Battlefield girl Danielle had already thought of the worst result.

"Okay." The female pilot Hannah Leche immediately returned to the carriage and used her dedicated line to dial the V2 rocket research team. Soon she returned to the director's carriage worriedly.

"Are they also disappeared?" the female reporter had already thought of it.

"Yes. Since the secret experimental field where the V2 rocket was developed on Usedom was blown up by Allied air strikes (the original plot of "Death Valley"). Later, all the staff of the experimental field moved to a secret factory built in the hollowed-out mountain to continue the research and development of the V2 rocket. I tried to contact my former superiors, and the local operator told me that the secret factory had been closed and it was said that it was also destroyed by an Allied air strike (the original plot of "Death Valley"). The personnel in the secret factory were also ordered to move elsewhere." said Hannah Lech, a female pilot.

"Referring to the real history of World War II, the person in charge of the entire V-shaped rocket development is Weiner von Braun." Battlefield girl Danielle said softly.

Wernher von Braun, known as the "father of modern space" and developed V1 and V2 rockets for Nazi Germany during World War II. After the war, many models of civil and military rockets in the United States and the first successful test flight were all invented by Wernher von Braun and his rocket team.

On March 23, 1912, von Braun was born in a noble family in Wilsitz, Germany, and later moved to Berlin with his family. In his childhood, Braun was full of curiosity. Once, he walked on a street in the Berlin Embassy District and suddenly bought six large fireworks from a fireworks shop, tied them to his scooter. After igniting, the scooter turned into a "rocket car" and glided quickly. He was very obsessed with his hobby of space, and perhaps influenced by his mother, because his mother was an amateur astronomy enthusiast.

After graduating from high school, Braun was studying the development of rockets like other amateur rocket enthusiasts in Germany at that time. The German Space Travel Association has been working hard to create a more advanced rocket. Braun, as one of the core figures, was preparing to help him launch the junior version of the rocket in 1931. Several local businessmen even spent money to watch, but the result was a complete failure. From then on, Braun gradually realized that if no one sponsored his space dream, it would be a beautiful fantasy.

Just when Braun was frustrated, the German Army found him in 1932 and expressed his willingness to fully support his doctoral thesis, but it must be used as a military secret. This was undoubtedly an excellent opportunity for Braun. He did not hesitate to accept the olive branch from the other party. Less than a year of rocket research for the army, Braun and his boss Dornberg arranged a secret launch demonstration for the Army Commander-in-Chief. They planned to launch two A-2 rockets, which is the prototype of the V2 rocket. The demonstration on Bolcombe Island was very successful. The rocket flew completely according to the scheduled plan, and made major breakthroughs in both flight altitude and flight trajectory.

In 1939, Weiner von Braun met with Nazi head Hitler. After reading the demonstration report, Hitler expressed his belief in Braun's ability and was willing to invest more financial support for rocket research. At the same time, he also asked Braun to produce tens of thousands of rockets and throw them all to Britain. Because in Hitler's view, if he could throw thousands of such rockets into British territory every day, he could prevent Britain from attacking Germany to the greatest extent. To this end, Braun found a suitable missile test base, Penemide, and began to study the new weapon program, the V2 rocket plan. Hitler always wanted to use V2 to save the decline in the battlefield in World War II and urged Braun to produce as many V2 rockets as possible.

Finally, on Saturday, October 3, 1942, the first ballistic missile built by Weiner von Braun was successfully launched, taking off with a weight of 11 tons, flying 190 kilometers across the atmosphere, and finally falling into the Baltic Sea. In World War II, the missile he developed was one of Hitler's secret weapons, and he struggled to save Germany's defeat.

In July 1943, Braun and his assistants went to Hitler's secret headquarters, Wolf's Knot, to show a short video of a V2 launch. Hitler was impressed by this, rumored that he said, "If we had these rockets in 1939, this war would not have happened." There was an order to start mass production. A month later, the RAF launched a large-scale bombing on Penemide because they suspected that the base was used to build rockets, and the plan was in chaos. The raid had only limited success, but it did force the Nazis to transfer the rocket manufacturing facilities to an underground factory in the Harz Mountains in Nordhausen, the highest

The priority projects will be released there. They are further bombarded by any Allied forces. Here, under harsh conditions, slave laborers from nearby Dora concentration camps worked hard to produce V2 rockets. They worked and lived underground, without fresh air and natural light, without food and rest, and were violently abused by SS guards. In fact, more people died in the creation of V2 than in actual combat. The large number of slave laborers who died for the production of V2 rockets became the spot for criticism of Braun and his V2. According to incomplete statistics, more than 20,000 of the more than 60,000 workers at that time died of illness, hunger and torture.

When the first V2 rockets attacked London, less than a year before World War II, the situation was completely unfavorable to Germany. In early 1943, the Soviet Red Army won a hard-won victory in Stalingrad, and then the Nazi forces retreated on the Eastern Front. In June 1944, the U.S., Britain, Canada and its allies landed in Normandy and began to attack from the west. Hitler knew that if he wanted to avoid a terrible defeat, his fate would require a dramatic turn. Therefore, he ordered the start of the "Vengeance Weapon 1, V1": a flight bomb developed by the Luftwaffe and V2. The first of them was launched at Britain on June 13, 1944, a week after Normandy landed. As it turned out, they had a serious blow to the frontline personnel.

In the fall of 1944, 4-6 rockets hit London almost every day. By the end of November, hundreds of rockets had flew to Britain, and no one could escape this supersonic silent weapon. Post-war materials show that in seven months, London was hit by 1,115 V2 rockets, each carrying a 1-ton bomb head. This resulted in the destruction of 20,000 houses and the death of 2,855 people. The psychological panic it caused was even more difficult to count.

On May 2, 1945, seeing that Germany was in a desperate situation, Weiner von Braun, the leader of Hitler's "revenge" weapon program, brought his space dream and eleven years of research results and 600 German scientists collectively surrendered to the US military, and was then quietly transferred to the United States.

That month, the Soviet Red Army also occupied Von Braun's research and testing facility in Penemide, the Baltic coast. Meanwhile, the French convened about 40 German rocket scientists and engineers, while the British assembled the rockets and conducted a series of test launches. The British plan, called Operation Against Fire, was to launch the V2 rocket to the edge of space from the Netherlands, and then the rocket crashed into the North Sea. The test proved successful, with the missile reportedly landing within three miles of the target - more precise than the Germans managed to do during the war. Engineers overseeing the test realized that Von Braun had solved the fundamental problem in rocket technology: he designed a considerable engine, advanced pumps and cutting-edge guidance systems that could draw fuel at a fast enough speed.

The importance of the V2 rocket cannot be overstated. As the world's first mass-produced liquid propellant rocket launch vehicle and the first ballistic missile, the shadow of the V2 continued until the 20th century.

Weiner von Braun provided the US military with 100 complete V2 rockets. In 1955, Braun and his colleagues officially became American citizen.

The Saturn V rocket developed in 1969 sent Armstrong to the moon, and the Cupid C launch vehicle sent the first US satellite "Expert 1" into its intended orbit. His outstanding achievements made him receive from US President Kennedy.

On June 16, 1977, Weiner von Braun died of colorectal cancer in Alexandria, Virginia.
