The U.S. dropped a GBU-43/B for the first time Thursday in Nangarhar Province, Afghanistan.
Commonly referred to as the Mother of All Bombs (MOAB), it weighs 21,000 pounds and has an explosive yield equal to 11 tons of TNT.
Why this matters:
Much was said about the MOAB being the most powerful non-nuclear bomb ever used in combat, but that comparison can overstate its size — it's just 0.073% as powerful as the nuclear bomb dropped on Hiroshima and modern nuclear weapons are many times stronger than that.
