I was looking for special missiles that do more than just explode or release radiation, thus I looked at some of the harder Warhammer 40k weapons, until I came across the Hellfire Missile.
To describe this:
"Hellfire is a common term for a potent acidic/viral compound developed by the Adeptus Mechanicus. It burns through armour and sears flesh, usually leaving the few who survive hideously scarred and crippled. It is a matter of opinion whether or not it is better to die from a Hellfire attack or to survive. Ordinatus Golgotha carries 6 Hellfire Missiles and can only fire 1 or 2 per hour. A Hellfire Missile has multiple warheads, allowing it to completely devastate a wide area. In addition, the extensive scanning equipment aboard Ordinatus Golgotha allows it to fire with unerring accuracy. The Hellfire Missiles can be fired at any point on the battlefield, even at targets that are out of line of sight, with no chance of scattering. Unlike normal indirect barrages, there is no need for friendly troops to spot for the accurate launch of a Hellfire Missile. Enemy units attacked by this horrendous weapon may be panicked by the agonised screams of their comrades, as their flesh burns away and their bones melt."
So, effectively this is essentially an acid bomb, that when detonated releases the acidic compound into the atmosphere, corroding all there is.
I ask if it is possible to dope a bomb with superacid or similar chemicals to achieve such an effect, given that there are materials like Teflon to store it in the first place.
Once again, assume all resources required are present.
