The V3 Versuchsanlage was a German experimental artillery testing site located in what is now Poland during World War II. This facility was part of the Nazi regime's development of the V3 cannon, a long-range artillery piece designed to bombard targets from extreme distances. The site was situated in the Pomeranian region, taking advantage of the area's terrain for testing these massive weapons.
The V3 project represented one of the Third Reich's most ambitious and technologically advanced military programs, though it ultimately proved impractical and was never deployed operationally.
