Brengun EMW Wasserfall C2 guided rocket 1:72
From Wikipedia, the free encyclopedia
The Wasserfall Ferngelenkte FlaRakete (Waterfall Remote-Controlled A-A Rocket[1]: 77 ) was a German guided supersonic surface-to-air missile project of World War II. Development was not completed before the end of the war and it was not used operationally.
The system was based on many of the technologies developed for the V-2 rocket program, including the rocket itself, which was essentially a much scaled-down version of the V-2 airframe. The rocket motor used new fuels as it was expected to be stored in ready-to-fire form for months, and the guidance system used external fins for control instead of relying entirely on the steerable rocket motor exhaust.
