This drawing illustrates the vital dimensions of the A-4 (Aggregate-4). Later renamed the V-2 (Vengeance Weapon-2), the rocket was developed by Dr. Wernher von Braun and the German rocket team at Peenemuende, Germany on the Baltic Sea. At the end of World War II, the team of German engineers and scientists came to the United States and continued rocket research for the Army at Fort Bliss, Texas, and Redstone Arsenal in Huntsville, Alabama.
