The V-2 (for Vergeltungswaffe 2, &quot;retaliation weapon 2&quot;, technical name Aggregat-4, or A-4), was a missile developed by Wernher von Braun and Klaus Riedel as part of a German military research team. Commonly known as the V-2, it was the first combat ballistic missile and the progenitor of all modern rockets, including those used by the U.S. and USSR space programs. Its first successful flight was in 1942, and from 1944 to 1945 over 3,000 V-2s were launched. Photographed at Peenemünde…
