patgundSecret Rocket Balls Target WMD Bunkers
"The Pentagon has a new secret weapon to neutralize sites containing chemical or biological weapons: rocket balls. These are hollow spheres, made of rubberized rocket fuel; when ignited, they propel themselves around at random at high speed, bouncing off the walls and breaking through doors, turning the entire building into an inferno. The makers call them "kinetic fireball incendiaries." The Pentagon doesn't want to talk about them, but published documents show that the fireballs have undergone tests on underground bunkers.
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 a not a good idea. Using high explosives is likely to scatter then over a wide area, which is exactly what you want to avoid.
Two special high-temperature incendiary bombs — named "CrashPAD" and "Shredder" — were quietly rushed into service for the use against WMDs few years ago. CrashPAD is based on the Mk.84 bomb and is intended for soft targets; the BLU-119/B Shredder is a modified BLU-109 bunker-buster for hardened or underground targets. The filler for both is a combination of explosive and incendiary, which is more effective than explosive alone, but hardly safe. An explosion causes overpressure and releases a plume of hazardous material. However, without any explosive the incendiary will not be adequately dispersed.
The incendiary must also maintain the temperature for a prolonged period, to ensure that anything dangerous is destroyed. That means heating up the entire structure for more than just a few seconds. Existing incendiaries tend to burn fiercely but quickly.
One solution is replacing the standard explosive or incendiary with a load of kinetic fireballs, described in this proposal. Each fireball is a hollow spherical shell with a hole in it; when the inside is ignited, the hole acts as a rocket nozzle. The kinetic fireballs eject an extremely high-temperature exhaust which will heat up the surrounding volume to over 1,000 F within seconds. Their random ricocheting around ensures that they will fill any space they occupy, and they are capable of diffusing throughout a multiroom structure."
