Associated Launch Sites
  • Cuxhaven As the only site in Germany with an unrestricted over-water firing sector over the North Sea, Cuxhaven was once touted as 'the Cape Canaveral of Germany'. Primarily known to space historians for the three post-war V-2 launches under project Backfire, it played an important role in the nascent post-World War II German rocketry. A nearly completely unknown series of scientific sounding rocket launches were made from the area in 1957-1964 before the launch site was closed on (purportedly) safety and (actually) military grounds.
