A small primary charge bursts the container, aerosolizing the fuel (liquid or solid particles) into a massive cloud that mixes with the surrounding air.
FAEs are notorious for their effectiveness in like bunkers, tunnels, and caves, where the fuel cloud can flow around corners before igniting. fuel-air explosive
This creates a that lasts significantly longer than conventional "point-source" explosions, making it far more destructive to structures and unarmored personnel. Performance vs. Conventional Explosives Fuel-Air Explosive (FAE) Conventional (TNT) Energy Source Uses atmospheric oxygen Carries internal oxidizer Energy Release 7.9–11.3 kcal/g (Propylene Oxide/Decane) 1.1 kcal/g Blast Profile Slower, sustained pressure wave Rapid, high-intensity shock Efficiency High energy-to-weight ratio Lower relative energy Lethality and Physical Effects A small primary charge bursts the container, aerosolizing
