China Review News reported on November 12, 2012, that China has developed the CM-506KG Airborne Smart Ammunition Series. Called the “Diamond Back” bomb, it can effectively destroy targets on the ground or in the water as far as 130 kilometers (80 miles) away; it is comparable to a similar U.S. made bomb.
