Abstract: A munition including a submunition has a target detector and a core-generating charge with a firing axis .DELTA. for firing a projectile. The munition is designed to move relative to the ground and seek a target. The munition rotates about an axis A with a velocity translation v.sub.0. The target detector includes several detection axes .delta..sub.1 through .delta..sub.n and a device for selecting a detection axis .delta..sub.i from the detection axes .delta..sub.1 -.delta..sub.n for which the distance E between the point M.sub.i at which the axis .delta..sub.i intersects the ground and the point M' at which the projectile strikes the ground is minimal.

Abstract: A directed-effect submunition moves in a substantially vertical direction V with a displacement velocity v parallel to V and a rotation velocity r about an axis parallel to V. The submunition includes a shaped charge with axis D forming an acute angle t with axis V and a detection device with axis d forming an angle u with axis D, a target detecting device, and a triggering device. The submunition also includes a displacement velocity v determining device, and a calculation device for calculating as a function of v a value u.sub.i for angle u that minimizes deviation (e) between the position (M) of a target detected, and impact point (M') of the penetrator of the shaped charge if the latter were triggered upon detection, as well as a device for imparting the value u.sub.i to angle u.
