Which facility was the world's first long-range guided ballistic missile tested at?
V-2 rocket 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 a liquid-propellant rocket engine was developed during the Second World War in Germany as a "vengeance weapon", assigned to attack Allied cities as retaliation for the Allied bombings against German cities. The V-2 rocket also became the first artificial object to travel into outer space by crossing the Kármán line with the vertical launch of MW 18014 on 20 June 1944.
National Transonic Facility (Hampton, Virginia) The National Transonic Facility (NTF), also known internally as facility 1236, is a high-pressure, cryogenic, closed-circuit wind tunnel at the Langley Research Center in Hampton, Virginia. It uses nitrogen gas, at high pressure, to cool the air which allows flight aerodynamics to be duplicated in small scale. The cross section of the tunnel is 8.2 ft high and 8.2 ft wide. Unlike full-scale wind tunnels, the NTF can adjust airflow to match any model size down to 1/50 scale. The facility can operate liquid nitrogen is sprayed into the circuit or at ambient air temperature.
