A protector for propelling charge increments on a mortar shell includes a semi-cylindrical body, the semi-cylindrical body arranged around a bottom and sides of the charge increments; two generally horseshoe shaped end plates attached to a front and a rear of the semi-cylindrical body, the end plates defining openings therein, the tail tube of the mortar fitting in the opening in each end plate, the charge increments being disposed between the two end plates; a wedge-shaped boom attached to the rear end plate, the wedge-shaped boom fitting between two fins on the fin portion of the mortar shell; a stop tab attached to a rear end of the wedge-shaped boom, the stop tab extending substantially perpendicular to a narrow side of the wedge-shaped boom to contact an end of the fin portion thereby minimizing longitudinal motion of the charge increments; and a nose cone attached at the front of the semi-cylindrical body, the nose cone defining an opening at its front end, the middle portion of the mortar shell fitting in the opening.

1. An Apparatus comprising:a mortar shell, the mortar shell including a front portion, a middle portion, a tail tube and a fin portion, the fin portion comprising a plurality of fins, the middle portion having a generally decreasing cross-section in an aft direction, the tail tube being of substantially constant cross-section: a plurality of charge increments disposed on the tail tube, the charge increments having a generally horseshoe shape defining an opening therein, the tail tube fitting in the opening in each charge increment; and a protector for the charge increments, the protector comprising: a semi-cylindrical body, the semi-cylindrical body arranged around a bottom and sides of the charge increments; two generally horseshoe shaped end plates attached to a front and rear of the semi-cylindrical body, the end plates defining openings therein, the tail tube fitting in the opening in each end plate, the charge increments being disposed between the two end plates; a wedge-shaped boom attached to the rear end plate, the wedge-shaped boom fitting between two fins on the fin portion; a stop tab attached to a rear end of the wedge-shaped boom, the stop tab extending substantially perpendicular to a narrow side of the wedge-shaped boom to contact an end of the fin portion thereby minimizing longitudinal motion of the charge increments; and a nose cone attached at the front of the semi-cylindrical body, the nose cone defining an opening at its front end, the middle portion of the mortar shell fitting in the opening. 2. The apparatus of claim 1 wherein the protector comprises polycarbonate/acrylonitrile butydiene styrene (PC/ABS) plastic alloy.3. The apparatus of claim 1 further comprising foam attached to an interior surface of the semi-cylindrical body.4. The apparatus of claim 3 wherein the foam comprises two rectangular strips.5. The apparatus of claim 3 wherein the foam comprises polyether polyurethane.6. The apparatus of claim 1 further comprising foam attached to an interior surface of the frontend plate.7. The apparatus of claim 6 wherein the increment insert comprises polyethylene foam.
