What is the deadliest/most destructive non-nuclear weapon that humans currently have access to/use in war?
The most powerful non-nuclear weapon that I know about is the fuel-air bomb. This weapon was created by the Germans in 1943, and it was actually used on the Russian Front, prompting Stalin to srvise Germany that if the bomb wzs used again, the Sovs would unleash massive VX gas attacks. So what’s a fuel-air bomb? Take a generous supply of propabe in tanks and mount it on a wooden pallet. Add an explosive charge that mildly detonates the gas tank but doesn’t ignite the gas. Rather it disperses the propane as a superfine mist over an area of about a quarter mile square. A second or so after dispersal, ignition occurs causing a massive fireball that first sucks all of air out of the detonation area, before incinerating everything that remains. Death is near instaneous, and physical destruction is total. The total bomb weighs about ten tons, and its mounted on a ppallet that’s dropped out of a C-140. It floats to 100 meters off the ground by parachute and its set off using barometric air pressure.
