Technical Data on the Development of the A-4 (V-2)

The V-2 (German: Vergeltungswaffe 2, "Retribution Weapon 2"), technical name Aggregat-4 (A4), was the world's first long-range guided ballistic missile. The missile with liquid-propellant rocket engine was developed during the Second World War in Germany as a "vengeance weapon", designed to attack Allied cities as retaliation for the Allied bombings against German cities. The V-2 rocket was also the first man-made object to cross the boundary of space.
