Boeing has delivered the 500th Focused Lethality Munition (FLM) to the U.S. Air Force this month, completing the contract for the low-collateral-damage weapon 100 percent on time and on cost.

"This Direct Attack FLM team not only delivered to our customer with remarkable efficiency, but also provided an important tool to protect the lives of U.S. and coalition forces around the world," said Gary Rodenberg, Small Diameter Bomb program manager for Boeing.

FLM, a derivative of the Small Diameter Bomb, uses a multiphase-blast explosive compound along with a carbon-fiber-composite warhead case to minimize fragmentation, as well as an anti-jam Global Positioning System aided by inertial navigation.

The guided weapon provides a standoff range of more than 60 nautical miles to protect aircrews engaging threats in combat. The Air Force has dropped 23 FLMs in combat operations and has a 23 for 23 mission-success rate.
