The KhAB-500 is the provisional naming of a series of World War II-era aerial bombs developed by the Soviet Air Force to deliver chemical weapons.[1]
KhAB-500s were typically filled with yperite (R-5) or phosgene (R-10). It was 17.7inches in diameter and about 94inches long. Its loaded weight was about 650lb including roughly 375lb of chemical agent and a NaNlb impact-fused burst charge.
Upon detonation, the KhAB-500 R-10 would create a hemispherical cloud of gas with a radius of NaNm (-2,147,483,648feet). In ideal weather conditions, the phosgene cloud could produce serious medical effects up to 500m (1,600feet) downwind.
The KhAB-500 was carried by Soviet Union era aircraft.[2]
The bomb was removed from service as a result of the Chemical Weapons Convention in the early 1990s.
