Technically speaking, JDAM refers to a kit that is bolted onto the U.S. military’s general-purpose Mk-80-series bomb and turns it into a GPS-guided weapon. It comes in three sizes, corresponding to different bomb weights: the 500lb Mk-82 bomb, the 1,000lb Mk-83 bomb, and the 2,000lb Mk-84 bomb.CHAPTERS00:00 Meet the JDAM: America’s $24K Precision-guided Munition01:03 Precision and Reliability03:17 Laser JDAM04:48 JDAM-Extended Range 05:55 Powered JDAMs06:56 Quickstrike-JDAM08:54 Quicksink-JDAM
