Overview
GBU-39A/B FOCUSED LETHALITY MUNITION (FLM)
The FLM is a variant of the Small Diameter Bomb I that changes its casing and internal fill, in order to produce more devastating effects within a smaller confined volume. L3Harris provides the carbon-fiber-wound casing for the FLM to Boeing.
BLU-129/B
A carbon-fiber bomb body disintegrates instead of fragmenting, which adds explosive force nearby, but lowers collateral damage. This effect is especially beneficial in urban areas, in situations where friendly elements are close to the impact zone.
