The BLU-97 has become the most well known and the most notorious of submunitions. This may be because it has been deployed more than others by US forces in recent years. It may be because their fuze system can be so sensitive to movement that accidents with unexploded examples are hard to avoid. Generally air dispersed from CBUs, the BLU-97 has caused deminer fatalities after Gulf War 1, Kosovo, Afghanistan and Iraq following Gulf War 2.
When unarmed, the BLU-97 looks like an elongated yellow beer-can with a serviette attached to one end. The cloth drogue may be many colours and is not a full parachute, merely a drogue to orientate the munition as it falls.
