WATCH: GBU‑57 “MOP” in Action The U.S. Air Force has released new test footage of the GBU‑57 Massive Ordnance Penetrator (MOP) — a 30,000‑lb bomb designed to destroy heavily fortified underground targets. The release comes after seven B‑2 Spirit bombers dropped 14 MOPs during Operation Midnight Hammer, striking Iran’s most protected nuclear sites: • 12 bombs hit the Fordow enrichment facility • 2 hit the Natanz nuclear site • Separately, Tomahawk cruise missiles targeted the Isfahan Nuclear Technology Center The GBU‑57 is the most powerful non-nuclear bomb in the U.S. arsenal, capable of penetrating 200+ feet of reinforced concrete and earth. This marks the first-ever combat use of the weapon. #GBU57 #MOP #MassiveOrdnancePenetrator #B2Spirit #OperationMidnightHammer #Fordow #Natanz #Isfahan #BunkerBuster #StealthBomber #IranStrike #Airstrike #NuclearSites #MilitaryPower #VigilantHeroes #RotatePhone #BreakingFootage #DefenseNews #AviationReel
