The Fieseler Fi 103, better known as the V-1 (German Vereltunswaffen 1, "retaliation weapon 1") and Buzz Bomb, also colloquially known in Britain as the Doodlebug, was an early pulse-jet -powered predecessor of the cruise missile.
The V-1 was developed at Peenemunde Airfield by the German Luftwaffe during the Second World War. During initial development it was known by the codename "Cherry Stone". The first of the so-called Vergeltunswaffen series designed for terror bombing of London, the V-1 was fired from "ski" launch sites along the French (Pas-de-Calais) and Dutch coasts. The first V-1 was launched at London on 13 June 1944, one week after (and prompted by) the successful Allied landing in Europe.
