Actually the one time it was used was just after it replaced an earilier air-fuel bomb, In 2017, Trump dropped one in Afghanistan to evaporate a poppy field and say to the Taliban, "here's what we can do." There's a flash and everything within a 1,000 yard radius is vaporized. Mushroom cloud. Biggest boom from a non-nuke ever. They drop it from a cargo plane not because it weighs so much, but because the dimensions are so large it doesn't fit inside the B1 or B2.Hmm actually afaik the MOAB was never really be used.
The only recorded drop was during the hot situation when Iraq was treathening to invade Egypt (if I'm not wrong): the drop it in a ttest field conventionally situated on the Egypt border with Iraq. A few days leater Iraq retrive the troop that wae assembling near the border...
The MOAB is not in fact a hight explosive bomb, is a ari-sol one: it work by praying hight falmable/explosive liquid/gas (sorry don't know THAT much of the specifcs) in the air and then detonate it with a much much bigger boom do to the air expansion.
Basically it use the same principle of the atomic bomb or of the "area bombing" tecnique, just in a "compact" version and without that nasty radiation-thing to mess with.
The real impact on the enemy is fear, which it delivers in boatloads.
