GSX
152
Cheap mixture of ammonium nitrate, water, aluminium powder and
polystyrene adhesive as a bonding agent. First used in the 6.75 t free
fall bomb BLU-82 (“Daisy cutter” or “aerosol bomb”). The peak pressure
of the bomb ignited approximately 1 m above ground reaches 70
bar in a radius of 30 m. GSX has been used for mine field clearing
and for “Instant helicopter landing zones” in the Viet Nam jungle-war.
