The Pentagon has been developing a weapon system of highly flammable and intensely hot rocket balls to help destroy weapon of mass destruction (WMD) bunkers.
These "kinetic fireball incendiaries" are specially designed to rocket randomly throughout an underground bunker while expelling super heated gases that rise over 1,000 degrees Farenheit.
These rocket balls are specifically designed for destroying potentially dangerous materials — such as chemical or biological weapons — without blowing them up, which would risk scattering the materials into the surrounding area, Wired notes.
"There are plenty of bombs which could destroy a lab, and bunker-busting weapons can tackle hardened underground facilities. But blowing up weapons of mass destruction is not a good idea. Using high explosives is likely to scatter them over a wide area, which is exactly what you want to avoid," Wired writes.
Instead, the fireballs function alongside a 2,000 pound BLU-109B bunker bomb, Flight Global reports. These bunker bombs are able to punch through six feet reinforced concrete. After punching into a bunker, the bomb would then release its internal kinetic incendiaries.
Once inside a bunker or structure, the rocket balls get to work. Essentially, the balls are hollowed out spheres comprised of rubberized rocket fuel that have a hole on the outside. As Technovelgy notes, this hole causes the balls, once ignited, to expel hot air in excess of 1,000 degrees Fahrenheit.
Additionally, the expulsion of air causes the incendiary balls to rocket wildly throughout a structure with enough force to break down doors. This allows the balls to randomly and fully reach the entirety of a bunker while incinerating everything inside.
Wired also notes that the use of such incendiary devices could allow the military to effectively clear out a building without damaging the structure's integrity, as well as effectively dealing with a nuclear facility without spreading nuclear material into the atmosphere or surrounding region.
