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.
Eglin AFB Site C-6 Eglin AFB Site C-6 is an Air Force Space Command radar station which houses the AN/FPS-85 phased array radar, associated computer processing system(s), and radar control equipment (e.g., MIT Radar Calibration System in 1996). Commencing operations in 1969, the AN/FPS-85 was the first large phased array radar. The entire radar/computer system is located at a receiver/transmitter building and is supported by the site's power plant, fire station, 2 water wells (for 128 people), and other infrastructure for the system. As part of the US Air Force's Space Surveillance Network its mission is to detect and track spacecraft and other manmade objects in Earth orbit for "the Joint Space Operations Center satellite catalogue". With a peak radiated power of 32 megawatts the Air Force claims it is the most powerful radar in the world, and can track a basketball-sized object up to 22,000 nautical miles from Earth.
