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.
W65 The W65 was the Lawrence Livermore Lab's competitor for the warhead of the Sprint anti-ballistic missile. Development of the W65 started in October 1965 and was terminated in January 1968 in favor of the Los Alamos W66 design. The W65 was an "enhanced radiation" weapon whose kill mechanism was the neutron flux.
