The BLU-108 is an air-delivered submunition, containing four further smart "Skeet" warheads.
The BLU-108 is released from a munitions dispenser, with a parachute being used to slow its descent.
It then fires the four rapidly rotating skeets, which use multi-mode optical sensors to identify a variety of targets ranging from tanks and missile launchers to railway locomotives and stationary aircraft.
When the skeet passes over what it considers a high priority target (this priority can be changed prior to employment), it fires a 0.9 kg (2 lb) explosively formed penetrator providing armor-piercing and incendiary effects, as well as a fragmentation ring meant to damage any soft targets, primarily enemy personnel, in the immediate vicinity of the target.
