JDAM ER bombs get smarter

JDAM is a low-cost guidance kit that converts existing unguided free-fall bombs into accurately guided "smart" weapons. The JDAM kit consists of a tail section that contains a Global Positioning System/Inertial Navigation System and body strakes for additional stability and lift. The incorporation of the Extended Range wing kit extends JDAM's standoff range. The baseline JDAM has been sold to the U.S. Air Force and the U.S. Navy, as well as to 22 international customers.
