The Dual Mode Guided Bomb: more versatile, more accurate

June 10, 2005 Tests of the U.S. Navy's latest guided bomb variant the Dual Mode Guided Bomb (DMGB) are going particularly well. The public first became acquainted with guided bombs during the first gulf war through TV imagery of bombs so accurate they could enter specific windows of a building. Of course, the less accurate bombs weren’t shown, though the accuracy improved more than tenfold before the second gulf war. Now the DMGB takes that basic guided munition form factor and makes it even more versatile. When using dual-mode guidance, the Global Positioning System/Inertial Navigation System (GPS/INS) data is used to bring the weapon close to the target, with laser guidance used in the terminal phase for improved end-game performance. Though this capability was previously available on very expensive precision guided weapons, the DMGB offers high accuracy and versatility at an unprecedented low price.
