Sd2 Butterfly Bombs

Anti-personnel bombs

Though the Luftwaffe employed a range of anti-personnel bombs, the one that was used on a large scale against the UK was the Sd2, the so-called Butterfly bomb. These 2kg bombs were dropped in containers that held 23 bombs or more. Once dropped the containers were blown open by an air burst fuze scattering the Sd2's far & wide. As the bombs fell the outer case flicked open by springs which caused four light metal drogues with a protruding 5 inch steel cable to deploy in the form of a parachute & wind vane.  This device moved up the cable & rotated, this action turned the spindle that was screwed into the fuze as a safety device, thus arming the bomb. The Sd2 came in two variants, the Sd2 and Sd2B. The Sd2 & Sd2B were both used against the Civillian population in many towns & areas throughout the UK.
