U.S. Used Its New 5,000-Pound Bunker Busters to Hit Iranian Anti-Ship Missile Sites: Reports
19th March 2026
The U.S. Air Force is now reportedly dropping its newest bunker-buster bomb, the 5,000-pound class GBU-72/B, on targets in Iran. The bombs are said to have been used in strikes on hardened Iranian anti-ship cruise missile sites along the highly strategic Strait of Hormuz overnight.
There are also reports that this is the first time GBU-72/Bs have been used in combat, but it is not clear if this is the case.
“Hours ago, U.S. forces successfully employed multiple 5,000-pound deep penetrator munitions on hardened Iranian missile sites along Iran’s coastline near the Strait of Hormuz,” U.S. Central Command (CENTCOM) wrote in a post on X, which did not name the munitions in question, last night. “The Iranian anti-ship cruise missiles in these sites posed a risk to international shipping in the strait.”
