Redl-Zipf

The Redl-Zipf V-2 rocket facility located in central Austria between Vöcklabruck and Vöcklamarkt and established in September 1943 began operation for V-2 rocket motor testing after Raxwerke test equipment had been moved from Friedrichshafen.The facility tested V-2 combustion chambers' compatibility with turbopumps since the rocket did not have a controller for reducing the turbopumping of propellant into the chamber if pressure became too high. The World War II facility used as a starting base the cellars and storage tunnels of an old brewery. Construction of the facility was under the command of SS-Obergruppenführer Hans Kammle who was responsible for Nazi civil engineering projects and its top secret weapons programs and used forced labor from the Schlier-Redl-Zipf: 207  subcamp of the Mauthausen-Gusen concentration camp. The construction added a large number of tunnels and supporting structures and included a liquid oxygen generation plant in one of the tunnels.
