Abstract
Abstract In a munitions system, a cylindrical canister is fired over a target. The canister carries a target sensing infrared device and, when a target is detected, a projectile is fired downward from the bottom of the overflying missile. A spinning motion is imparted to the missile to stabilize its flight, and a wobbling motion is imparted to the missile to provide a larger target area. The projectile forms a concave lower end to the missile and is fired by an explosive charge.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
93 words
A munitions system comprising: a missile having a projectile mounted for downward firing from the bottom of the missile; means for propelling the missile along a trajectory to overfly a target; stabilizing means for stabilizing the missile in flight with the projectile directed downward; means for imparting a lateral precession motion to the missile relative to the target; detector means carried by the missile for detecting a target below the missile; and means carried by the missile for propelling the projectile downward from the missile toward the target upon detection of the target.
Claim 2
Dependent Claim
93 words
A munitions system comprising: a missile having a projectile mounted for downward firing from the bottom of the missile; means for propelling the missile along a trajectory to overfly a target; stabilizing means for stabilizing the missile in flight with the projectile directed downward; means for imparting a lateral precession motion to the missile relative to the target; detector means carried by the missile for detecting a target below the missile; and means carried by the missile for propelling the projectile downward from the missile toward the target upon detection of the target.
