US 'Bunker Buster' Bomb: 910-kg Weapon Targets Iran's Nuclear Sites
•The 910-kg 'bunker buster' bombs are precision-guided munitions designed to destroy heavily fortified underground targets like nuclear facilities and military bases.
•Unlike standard bombs, these penetrate deep into the ground or reinforced structures before exploding, maximizing damage to subterranean networks.
•The GBU-31(V)3/B, based on the BLU-109 warhead and JDAM guidance kit, is a GPS-guided 'smart bomb' capable of accurate strikes in adverse weather.
•Measuring 7 feet 11 inches and weighing 910 kg, its hardened steel casing can penetrate several feet of reinforced concrete, packed with PBXN-109 explosives.
•Costing $40,000 to $70,000 per unit, these bombs are deployed by US fighter jets (F-15, F-16, F/A-18) and strategic bombers (B-2 Spirit), with Israel also using them in operations.
