September 27, 2006 Boeing has met the necessary U.S. Air Force requirement to support Initial Operational Capability (IOC) of the Small Diameter Bomb I (SDB I) weapon system, and the new four-bomb capacity carriage is ready for action. The first of a new generation of weapons whose small size and robust performance greatly increase mission capability, SDB I is an all-weather, 250-pound class weapon system that quadruples the number of weapons each aircraft can carry. At 71 inches long and with a standoff range of 60 nautical miles, the weapon is compatible with every U.S. fighter and bomber aircraft and Boeing will manufacture more than 24,000 such weapons and 2,000 carriages for the U.S. Air Force. The Air Force is investing US$1.2 billion for production, with deliveries planned beyond 2015. Great image gallery.
