Description
The purpose of a supplementary charge is to aid in the detonation of the explosive filler upon activation of the fuze.
Supplementary charges are placed in the fuze well of all HE deep cavity howitzer rounds from 75mm to 8 inch; in the 175mm Field Gun and in the 4.2 inch mortar projectiles. They are removed from the deep cavity when proximity fuzes with the extra large (long) booster or expelling charge, i.e., the M513, M514 Series and M728 but not the M732 or other proximity fuzes with the normal size booster. Supplementary charges are composed of approximately .30 lb of TNT pellets packed into an aluminum body cup. Supplementary charges are factory loaded into the HE rounds.
