The Sensor Fuzed Weapon is a United States Air Force 1,000 pound class non-guided, freefall, cluster bomb, hence the name CBU (Cluster Bomb Unit).

The CBU-97 consists of a tactical munition dispenser that contains 10 submunitions. Each submunition contains forty hockey puck shaped sensor fused projectiles called Skeets. These detect targets, such as tanks, armored personnel carriers, trucks and other support vehicles, and fire an explosively formed penetrator.

The 40 Skeets scan an area of 1,500 feet by 500 feet using infrared and laser sensors until it finds a target, or failing that, self destructs 50 feet above the ground. This harasses dismounted troops and prevents any rounds that do not explode immediately from hurting civilians later. There is also a back-up timer that enables the Skeet to time-out seconds after hitting the ground. These two redundant self-destruct modes results in an unexploded ordnance rate of less than 1%.

As the CBU-97 approaches its designated aim point, the dispenser skin is severed into three panels by an explosive cutting charge. The slipstream peels away these panels, exposing the 10 BLU-108 submunitions. An airbag ejects the forward five submunitions, then five in the aft bay. Following a preset timeline, the submunitions deploy parachutes so that they are spaced about 100 feet apart. Then each submunition releases its chute, fires a rocket motor that stops its descent and spins it on its longitudinal axis, and releases pairs of Skeets 90 degrees apart. Each spinning Skeet makes a coning motion that allows it to scan a circular area on the ground.

The 1000 Pound Cluster Bomb is an extremely effective weapon that dispenses 202 bomblets over an area the size of 16 football fields. The body of the submunition bombs are cylindrical in shape, approximately 20 centimeters long, and have a 6 centimeter diameter.

Cluster Bombs were used extensively for interdiction during Desert Storm. During Desert Storm the US Air Force dropped 10,035 CBU-87 bombs. During Allied Force operations the US dropped about 1,100 cluster bombs. By the end of November 2001, a total of 600 cluster bombs had been dropped over Afghanistan.

The Sensor Fused Weapon aka the 1000 Smart Cluster Bomb is an extremely effective weapon and the United States has not signed any agreement, with any Nation, not to use it again.
