Butterfly Bomb

The German SD 2 'Butterfly Bomb' was used on a large scale during the Second World War, and was designed as an anti-personnel/fragmentation weapon. They were delivered by air, being dropped in containers that opened at a predetermined height, thus scattering the bombs. When released, the casing sprang open to form a sort of parachute which also rotated the whole assembly, thus arming the fuze. Several types of fuze could be fitted, ranging from impact to clockwork anti-handling.
