US drops 900kg bomb on Isfahan: How 'bunker buster' dismantled Iran's defences

The night skies of the ancient city of Isfahan turned to blinding brightness after an airstrike. It is reported that a 2,000 pound or 900 kg bunker buster bomb hit an Iranian ammunition dump near the city.

• The Israelis have been using bunker buster bombs deployed by air to fight expansive tunnel and bunker networks in both Gaza and Lebanon.
• Aware of this extensive network, the American-Israeli coalition has made an extensive use of bunker buster weapons to hit these underground targets.
• The Israelis depend on their vast intelligence network to target these bunkers using specialised bunker buster guided bombs.In June of last year US Air Force B-2 stealth bombers dropped specialised GBU-57 Massive Ordnance Penetrator (MOP) on the Fardow and Natanz underground nuclear facilities in order to debilitate Iran's nuclear program.

Watch next: The current conflict has seen a tremendous use of bunker buster bombs as the Iranian forces have built an elaborate subterranean tunnel network in order to prevent the destruction of vital war waging assets as well as command and control networks under what the perceived would be protection from targeting from the air.The advantage for the defender here is that a defender who's infrastructure is underground is removed from observation of targeting apparatus and is also protected from the effects of regular bombs.
