A kinetic energy penetrator with a longitudinal axis may include a forward segment having a lateral surface, a rear surface, and at least one air bleed channel extending from the lateral surface to the rear surface. A second segment may be disposed aft of and torsionally engaged with the forward segment. The second segment may include a front surface adjacent the rear surface of the forward segment. The forward and second segments may each be asymmetric about the longitudinal axis of the penetrator. When the penetrator is in flight, bleed air through the bleed channels may impinge on the front surface of the second segment. The second segment may separate from the front segment. Kinetic energies of each of the forward and second segments may be less than about 75 joules upon impact with a ground surface.
