US B-2 stealth bombers flew 13,000km from Missouri to Iran, air-refuelled en route, to deploy GBU-57 “Massive Ordnance Penetrator” bombs – the heaviest conventional weapons (13,600kg) in America’s arsenal.
Designed to pierce 60m of concrete/rock before detonating their 2,400kg warheads, these bunker-busters target underground facilities like Fordow’s enrichment plant.
The B-2’s radar-evading stealth allows it to penetrate defended airspace undetected, though each bomber carries just two MOPs due to their size.
