The precursor to the [[V-2]], the German Vergeltungswaffe-eins was a pilotless aircraft or unguided missile launched from sites in northern France, Belgium and the Netherlands against south-east England. principally London. It was powered by a pulse jet engine, a primitive form of jet engine which was not used in manned aircraft because of its tremendous vibration when operating. It had a primitive guidance system  which at best gave it an accuracy of a few miles.
