Dasy Cutter Bomb 15,000 LBS. (BLU 15)

In late 1968 or early 1969 the 109th started rigging these large bombs used to clear landing zones (LZ's) in the Jungle for choppers. The bomb weighed 15,000 lb. and was nick named "Daisy Cutters". They were dropped by the US Air Force from C-130's. The mushroom clouds from the bombs exploding caused false reports of nuclear devices used in Vietnam. It's not clear exactly what other QM AD units rigged these bombs.
