Lieutenant Colonel Dahlges firmly memorized the words "saturation attack", and recently the Führer has inadvertently revealed a lot of new words, and when he first heard it, he felt strange and surprised, but after thinking about it again, he felt very convincing and generalized, which shows that the Führer not only stands tall and far-sighted, but also has more innovation and insight than ordinary people. As a motivated aide-de-camp, he was determined to record and disseminate the Führer's thoughts, and he was sure that Minister Goebbels would be impressed by him.

The spy storm was solved in the midst of talking and laughing, and this special encounter coupled with the characteristics of the V1 rocket basically determined that it could not be mass-produced, at least not in Germany, and that it would not be mass-produced in Germany, Hoffman decided to throw this burden on the crazy Japanese, first, to add blockage to the Americans, and secondly, to exchange some real money from Japan, not to mention anything else, it is good for Japan to use submarines to transport some tungsten, tin, rubber and other materials.

After looking at the two experimental projects, the next project introduction is only a theoretical introduction and a static model display, even if there is a real thing that can be operated, Dornberg, who has just escaped, does not dare to show it again.

"Führer, look, this is a model of the Feuerlilie rocket project."

Dornberg led the group to the third project test site, "At first it was a project of the Imperial Aviation Department (RLM) to study high-speed flight, and after receiving the task of developing an anti-aircraft rocket, Dr. Braun and Dr. Busemann, who were in charge of the project, unanimously decided to design it according to the air defense rocket, which currently has two design models, namely F25 and F55 (the numeric code represents the diameter of the projectile body in centimeters). ”

Braun explains, "They share the same codename, but they're actually different products. The F25 uses a solid diethylene glycol ether rocket engine with a working time of 6 seconds and an estimated thrust of 500 kg. We designed it as a transonic rocket that could be launched both from an inclined launch frame and from an aircraft. Judging by my calculations, it falls far short of air defense missions, with a top speed of about 950 km/h but an altitude of only 3,000 meters - which is significantly lower than the regular strike altitude of most bombers. ”

The F25 was originally just a sounding rocket, developed to collect aerodynamic data in the transonic zone, and in order to obtain funding and project support from the Ministry of Armaments, it was close to the nature of the anti-aircraft rocket, but Braun was not slow to move, not only making a model but also reserving a place for the warhead and fuse. The static model that appeared in Hoffman's eyes was an elongated cylindrical projectile, 2 meters long and expected to weigh 120 kilograms, with swept wings in the middle of the projectile body, winglets at the tips of the winglets, horizontal wings on the monolithic tail, and rudder surfaces on top to control the rocket's flight attitude.

The F55 model looks much more stout, with a length of 4.8 meters, which is both similar and different from the F25 in shape - tailless, with winglets at the end and winglets at the tips. According to the Buzeman design, it is a supersonic rocket, using a liquid-fueled rocket, designed to launch at an altitude of 5,000 meters, with a maximum speed of about 1,400 km/h.

"It is worth mentioning that the rocket engine of the F55 was designed by Dr. Conrad, who also designed the engines for two rockets of the 'daughter of the Rhein'. The thrust can reach about 6.5 tons, but the working time is a little shorter, only 7 seconds, which is why the rocket has not been as high as it should be. Braun knew that whether it was the F25 or the F55, there was an obvious flaw in the air defense mission, and he deliberately praised the other party at the end, "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, and if he hadn't died in an air raid in history, the Third Reich's research and development work in this field would have progressed even more, so he warmly shook hands with the other party, and Conrad was obviously grateful for Braun's recommendation, so he explained with a smile: "Dr. Braun mainly focused on the A-4 rocket, and he only studied the fire lily for the sake of supporting the project. The Rheinland daughter' was developed by Rheinmetall from the beginning in accordance with air defense standards, so the progress was faster. It is also available in two models, R1 and R3, where the R1 type is a two-stage solid fuel and the R3 type is a liquid fuel plus a solid booster. ”

Following his introduction, everyone inspected the model of the "Rhine Daughter", which has a petal-like wing, the shape of the rocket looks much more elegant, with four tail wings at the lower end of the projectile body, six stabilizing wings in the middle, and four control wings at the head, with a total length of 5.74 meters and a maximum shooting height of 6,000 meters.

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 still exist on the drawings, such as the Hs117 surface-to-air rocket (internal code name "butterfly") designed by Dr. Wagner, which is also a two-stage engine rocket, the primary booster system uses solid fuel, 1750 kg of thrust enables the rocket to reach a speed of 1100 kilometers per hour in four seconds, and the secondary main thrust system uses liquid fuel, The engine is also being considered for the BMW 109-558 or Walter 109-729 model. The total design length is 4.3 meters, the weight is 420 kg, the ceiling is 11000 meters, but the warhead is only 25 kg.

For example, Dr. Richard Vogt presided over the design of the anti-radiation (radar) gliding bomb BV246, internally codenamed "Hail", designed against British radar stations. The bomb had a very simple shape, a cigar-shaped fuselage, slender wings, and a normally laid out tail. In the design, the two long main wings were cast from reinforced concrete, in order to take advantage of the high weight to ensure that the bomb and the carrier aircraft were separated cleanly and to avoid interfering with each other and causing danger. The flight process is planned to be controlled by radio command, and the maximum strike distance is 150 kilometers away, which is the same idea as the Hs293 anti-ship gliding bomb that has been successfully developed, except that the seeker and fuse are different.

Another example is the "Waterfall" air defense rocket developed by Dr. Walter Thiel on the basis of the A-4 rocket, which is smaller in size and flight time than the A-4, but the maximum launch height can exceed 15,000 meters. In the middle of the flight, two ground radars are used to irradiate the target and the rocket respectively, and the computer is used to calculate the azimuth difference and issue a radio command to make the rocket fly along the target irradiation radar beam; At the end of the flight, the rocket is controlled by a radio proximity fuse and an infrared homing head.

In addition to these relatively well-formed projects, there are also a number of preparatory projects reported by researchers, including the BV143 air-to-ship rocket, which is similar to the marine version of the V1, with a tentacle 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", which is planned to be controlled by radio command, and is also considering the development of a wire-controlled model, which also uses a 25-kilogram warhead.

Hoffman found that these projects were very comprehensive, including ground-to-air, air-to-surface, air-to-air, air-to-ship, surface-to-ship, surface-to-ground, anti-radiation, anti-tank and other types of rockets were all in the development process, covering almost all types that appeared in later generations, and the progress varied, some were basically close to completion, some were still in the experimental demonstration stage, and some were simply the products of design drawings. But no matter what kind of design and invention, it is the leading or even unique in the world, and he is proud of it. It is on the basis of this exploration and achievement that the United States and the Soviet Union have built a huge missile arsenal and developed considerable satellite and space industries on the legacy of the partition of the Third Reich. In order to win this war and continue to occupy the leading point of the world's science and technology, he is determined to tell these scientists everything he knows about missiles, although his research ability is not as good as that of any ordinary engineer, but when it comes to sorting out the missile system and describing the future development, he is the authority in the world.

Dornberg, who knew what the Yuan was doing, immediately found a large conference room, and quickly arranged the microphone and blackboard for Hoffman in the way of academic exchanges.
