Fuel-air Explosive 〈2024〉

Once the cloud reaches an optimal concentration—often between 186–275 g/m³ for common fuels—a second charge detonates the mixture.

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

Fuel-air explosives (FAE), commonly known as or "vacuum bombs," are specialized munitions that use atmospheric oxygen to create a high-temperature, long-duration explosion. Unlike conventional explosives that carry their own oxidizer, FAEs consist almost entirely of fuel, allowing them to release up to 400% more energy than an equivalent weight of TNT. Mechanism of Action commonly known as or "vacuum bombs

FAEs typically operate through a "two-stage" detonation process: FAEs consist almost entirely of fuel
