Iron Cross

Everyone was unanimously impressed by this unbridled idea, and began to imagine the scene just described by the head of state. Lieutenant Colonel Dargos firmly wrote down the words "saturation attack". Recently, the head of state has always revealed many new things inadvertently. The vocabulary felt strange and surprising when I first heard it, but after thinking about it again, I found it very convincing and summarized. It shows that the head of state not only stands high and sees far, but also has innovation and insight that ordinary people cannot match. As an ambitious adjutant, he was determined to record and disseminate the Führer's thoughts. He believed that Minister Goebbels would be impressed by him.

The espionage incident was resolved in a short chat. This special encounter and the characteristics of the V1 rocket basically determined that it would not be mass-produced, at least not in Germany. Hoffman decided to throw away this burden. For the crazy Japanese, firstly, it can cause trouble for the Americans, and secondly, it can exchange some real money from Japan. Among other things, it would be good for Japan to use submarines to transport some tungsten, tin, rubber and other materials.

After watching the two test projects, the next project introduction only consisted of theoretical introduction and static model display. Even if there were real objects that could be operated, Dornberg, who had just escaped, would not dare to show them off.

"Please see, Head of State, this is a model of the Feuerlilie rocket project."

Dornberg led everyone to the third project test base. "It was originally a project used by the Imperial Aviation Ministry (RLM) to study high-speed flight. After receiving the task of developing anti-aircraft rockets, the main person in charge of the project announced Dr. Lawn and Dr. Busemann unanimously decided to design it as an anti-aircraft rocket. Currently, it has two design models, namely F25 and F55 (the number code represents the diameter of the projectile in centimeters).”

Braun explained: "Although they share a code name, the two are actually different products. The F25 uses a solid diethylene glycol ether rocket engine with an operating time of 6 seconds and an estimated thrust of 500 kilograms. We designed it to be able to It is a transonic rocket that is launched from an inclined launcher and can also be launched from an aircraft. According to my calculations, it has great shortcomings in its air defense mission. Its top speed is about 950 kilometers/hour, but its shooting height is only 100 kilometers per hour. 3,000 meters - this is significantly lower than the conventional raid altitude of most bombers."

The F25 was originally just a sounding rocket. Its research and development purpose was to collect aerodynamic data in the transonic zone. In order to obtain funds and project support from the Ministry of Armaments, it moved closer to the nature of an air defense rocket. However, Braun was not slow in his actions. He not only produced The model has been modeled and positions have been reserved for the warhead and fuze. The static model that appeared in Hoffman's eyes was a slender cylindrical missile body, 2 meters long, estimated to weigh 120 kilograms, with swept wings located in the middle of the missile body, with winglets at the wing tips, and a single-piece tail fin. There are horizontal wings, and the rudder surface above is responsible for controlling the flight attitude of the rocket.

The F55 model looks much stouter. It is 4.8 meters long, and its appearance is both similar and different from the F25 - a tailless shape, the elastic wings are placed at the end, and there are small wings on the wing tips. According to Boozerman's design, it is a supersonic rocket, using a liquid fuel rocket, with a designed launch height of 5,000 meters and a maximum speed of about 1,400 kilometers per hour.

"It is worth mentioning that the F55 rocket engine was designed by Dr. Conrad, who also designed the engines for the two Reintochter rockets. The thrust can reach approximately 6.5 tons, but the work The time is a little shorter, only 7 seconds, which is why the rocket's shooting height has always been unsatisfactory. "Braun knows that whether it is F25 or F55, there is an obvious flaw of insufficient shooting height in the air defense mission. He specifically praised the other party and said, "The development progress of the two models designed by Dr. Conrad is faster than ours, and the indicators are more mature."

Hoffman knew Conrad's name. If he had not died in an air raid, the Third Reich's research and development work in this field would have made greater progress. So he shook hands with him enthusiastically. Conrad was obviously very grateful to him. Thanks to Braun's recommendation, he explained with a smile: "Dr. Braun mainly focused on the A-4 rocket. His research on Fire Lily was just to support the project, and the 'Rhine Daughter' 'But it was developed by Rheinmetall in accordance with air defense standards from the beginning, so the progress is faster. It also has two models, R1 and R3. The R1 model is a two-stage solid fuel, and the R3 model is a liquid fuel plus solid booster. "

Following his introduction, everyone inspected the model of the "Daughter of the Rhine". This rocket with petals-like wings looked much more elegant. There were four tail fins at the lower end of the missile body, six stabilizing fins in the middle, and the head It has four control wings with a total length of 5.74 meters and a maximum shooting height of 6,000 meters. It is controlled by radio commands and has a light-emitting device on the wing tip to facilitate visual remote control by the operator.

At the end of the visit, in addition to the model works, Hoffman and others also listened to some projects that have not yet been finalized or are still on the drawing board, such as the Hs117 ground-to-air rocket (internal code name "Butterfly") designed by Dr. Wagner. This is also a two-stage engine rocket. The primary booster system uses solid fuel. The thrust of 1,750 kilograms enables the rocket to reach a speed of 1,100 kilometers per hour in four seconds. The secondary main propulsion system uses liquid fuel. The engine is still considering using the BMW109-558 or Walter109-729 model. The total design length is 4.3 meters, the weight is 420 kilograms, the ceiling is 11,000 meters, but the warhead is only 25 kilograms.

For example, the anti-radiation (radar) glide bomb designed by Dr. Richard Vogt to deal with British radar stations - BV246, internal code name "Hail". This bomb has a very simple appearance, a cigar-shaped fuselage, slender wings and a normal layout of the tail. In the design, the two long main wings are cast with reinforced concrete. The purpose is to use the characteristics of heavy weight to ensure that the bomb and the carrier are separated cleanly and neatly to avoid mutual interference and danger. The flight process is planned to be controlled by radio commands, and the maximum strike distance is beyond 150 kilometers. It is the same idea as the successfully developed Hs293 anti-ship glide bomb, except that the seeker and fuze are different.

For example, the "Waterfall" air defense rocket developed by Dr. ******·Till on the basis of the A-4 rocket is smaller in size and flight time than the A-4, but the maximum firing height can exceed 15,000 meters. According to Dr. Till's development ideas, the ground operator visually controls the rocket when the speed is slow at the beginning of the launch, and controls its approximate shooting direction by adjusting the four graphite gas rudders of the tail nozzle; in the middle of the flight, two ground radars are used to illuminate the target and the rocket respectively, and the computer is used to solve the azimuth difference and issue radio commands to make the rocket fly along the radar beam illuminated by the target; in the final stage of the flight, the radio proximity fuze and infrared guidance head are used to control the rocket flight.

In addition to these relatively mature projects, there are also a variety of preparatory projects reported by researchers, including the BV143 air-to-ship rocket, which is similar to the sea version of the V1. There is a tentacles under the missile body to ensure that the rocket always flies at an altitude of 2 meters above the sea surface; another example is the Hs298 rocket, which is an air-to-air model based on the "butterfly". It is planned to use radio command control, and the development of a wire-controlled model is also considered. It also uses a 25-kilogram warhead.

Hoffman found that these projects are very comprehensive, including ground-to-air, air-to-ground, air-to-air, air-to-ship, ground-to-ship, ground-to-ground, anti-radiation, anti-tank and other types of rockets are in the development process, almost covering all types that have appeared in later generations, with different progress. Some are basically close to completion, some are still in the test demonstration stage, and some are simply the product of design drawings. But no matter what kind of design and invention, it is leading or even unique in the world, and he is proud of it. It was based on this exploration and achievement that the United States and the Soviet Union built a huge missile arsenal and developed a considerable satellite and space industry on the basis of the legacy of the Third Reich in real history. In order to win this war and continue to occupy the leading position in world science and technology, he decided to tell these scientists all the knowledge he knew about missiles. Although his research ability was not as good as any ordinary engineer, he was the authority in the world when it came to the arrangement of missile systems and the description of future development.

Dornberg, who knew what the Führer wanted to do, immediately found a large conference room and quickly arranged a microphone and a blackboard for Hoffman in the form of academic exchanges. Looking at the crowd of scientific research elites of the Third Reich under the stage, Hoffman took out the posture he had at the technical demonstration meeting of the Army Weapons Bureau and began to explain.
