Precision-guided Munition

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Precision-guided munitions (PGMs, smart munitions, smart bombs, guided bomb units or GBUs) are guided weapons intended to precisely hit a specific target, and to minimize damage to things other than the target. A guided bomb differs from a guided missile in that a bomb relies on the speed and height of the launch aircraft for propulsion, whilst a missile has an onboard engine. Because the damage effects of explosive weapons fall off with distance according to a power law, even modest improvements in accuracy (and hence reduction in miss distance) enable a target to be effectively attacked with fewer or smaller bombs. Thus, even if some bombs miss, fewer air crews are put at risk and the harm to civilians and the amount of collateral damage may be somewhat reduced.
