Developed by Germany during WWII, the Vergeltungswaffe 2 (V-2) Rocket was the world's first modern ballistic missile and the first artificial object to achieve suborbital spaceflight.

Approximately 20,000 slave laborers died producing the rockets for Germany, and 7,000 civilians perished during more than 3,000 attacks on allied targets. What does Vergeltungswaffe mean?
