Analyst Note:
MK 84 unguided air-delivered bombs can be fitted with a variety of tail kits, or with guidance kits which convert them into precision guided munitions (PGMs). When an air-delivered bomb impacts a building or the ground without functioning, the tail or guidance kit may be sheared off. With these separated from the munition—and in the absence of other identifying features, such as a seeker fitted to the nose of the weapon—it becomes very difficult to determine whether the bomb was guided or unguided.
