Code names of Nazi secret objects
During the Second World War , construction projects that were important to the war effort were usually given code names . This affected both above-ground structures and underground relocations. Many of the objects were not completed. Animal and plant names as well as first names were mainly used. The focus was on the U relocation program of the Jägerstab (underground production of fighter aircraft such as the Me 262 ), the A4 program (underground rocket production ) and the Geilenberg program (underground relocation of hydrogenation plants ).
System of the aliases at RMfRuK ( Reich Ministry for Armaments and War Production ):
Natural caves | Terms from the coinage |
Old shaft systems | Animal names of all kinds |
Old tunnel systems | Fish and amphibian names |
New tunnel systems | Geological designations |
Former bunkers | Terms from botany |
Deep basement | Female first names |
New bunkers | Male first names |
Traffic tunnel | Bird names |
But there were also other encryption systems such as capital letters or numbers. The Organization Todt used u. a. also a camouflage name system made up of river names (e.g. Elbe, Oker, Weser, Aller) and animal names plus dwelling (e.g. bear cave, eagle's nest). (Incorrect) company names were also used as aliases. The same object could have several names (e.g. for the SS-IKL and the RfRuK ).
