missile was located in the Thuringia area upstream of the Weiser River in central Germany. In the belly of Mount Constant, 4 kilometers away from Nordhausen, 5 huge longitudinal tunnels of about 3.5 kilometers each were dug, 44 horizontal tunnels of about 1 kilometer long. The central tunnel was a V-1 missile assembly line, the side tunnel was a V-2 missile assembly line, and the other tunnels were workshops for manufacturing various components, and were also equipped with inspection tables for horizontal and vertical inspections. This missile underground factory is listed as "Mittel", nominally affiliated with "Zepplin Aircraft Company", and produces 30-35 missiles every day. These two huge and secret missile bases were built by the Nazis forcing 100,000 prisoners of war.
With the successful development of the missile, these prisoners of war were also wiped out, and their blood and tears soaked every inch of land there. V-1 Rocket is essentially a drone propelled with pulse jet engine . The total length is 7.76 meters, the wingspan is 4.9 meters, the warhead is equipped with 1,000 kilograms of high explosives, the total weight of the rocket is 5,000 kilograms, the maximum flight speed is 640 km/h, the maximum flight altitude is 915 meters, and the maximum range is 320 kilometers. V—1 is launched on the inclined slide. The bullet is equipped with a fan-driven rotational counter. When the rotational number reaches a certain amount equivalent to the flight distance, the rocket will automatically turn into a sharp dive. When the rocket hits the ground, the electric fuse ignites the explosives, causing it to explode.
