A secret underground facility of the World War II German V2 rocket program

During World War II, Nazi Germany developed the first ballistic missile program in history: the famous V2.

The program had already started in 1935 under the name Aggregat 4, completing the first rocket in 1941, which was tested on June 13, 1942. This new weapon was operational in September 1944. strong>A total of 5,000 V2 rockets were built, which were launched over the United Kingdom and Belgium, killing more than 7,000 people, as part of the campaign of terror ordered by Hitler against the allied countries, based on two types of Vergeltungswaffen or revenge weapons: the V1 flying bomb and the V2 missile.

The manufacture of these weapons of revenge had to be done mainly in underground facilities , due to the systematic Allied bombing raids against the German armaments factories on the surface. For the construction of these underground factories and the missiles themselves, the Germans used tens of thousands of slave laborers brought from the occupied countries and taken from the concentration camps. These people had to work in inhumane conditions.

This Sunday, the channel Simply Adventure published a video in which It shows one of those secret underground facilities, in a location that is not indicated in the video or its description. Specifically, this installation was used to mix the components of the V2 fuel, made up of ethanol and liquid oxygen (the video is in German but it has subtitles in English, you can activate them in the bottom bar of the player):

You can see below some captures of the video. The explorers access these ancient secret facilities through a long tunnel one kilometer long, made with bricks and slate in some of its sections. In certain parts of the tunnel there is yellowish mud and considerable water seepage.

A document found by explorers in these underground facilities. It is written in a Gothic typeface, widely used by the nazis until the World War II, when they disowned it, believing it had a Jewish origin.

A wider tunnel, located at the end of the facility, in the part that would face the outside. In this area, rocket fuel tanks would be loaded onto trains.
