A precursor formulation of an energetic composition with improved electrostatic charge dissipation, including an amorphous carbon black having a specific surface area of at least about 1,200 m.sup.2/g, in an amount from about 0.05% by weight to about 0.25% by weight. Also disclosed is a precursor formulation of a propellant composition with improved electrostatic charge dissipation. The amorphous carbon black having a specific surface area of at least about 1,200 m.sup.2/g may enhance electrostatic charge dissipation of the HTPB-based propellant composition, without affecting a breakdown voltage of the propellant composition.
