The German-developed V-1 was an automatically controlled pilotless aircraft for use against Allied cities during World War II.
The missile was launched from ground ramps. Once in the air, automatic controls on board the craft took over. The V-1 climbed to a predetermined altitude, followed a compass course, and dove to the ground after a preset distance had been covered.
This mid-wing monoplane was powered by a unique pulsejet engine above the rear portion of the fuselage.
The relatively low speed of the missile made it easy prey for antiaircraft guns or fighters.
