1. A rocket motor comprising:
a casing having an axis;
a solid propellent;
one or more burn rate enhancement (BRE) wires embedded in the solid propellent along or parallel to the axis, each said BRE wire configured to burn to accelerate a burn rate of the solid propellent;
one or more first embedded charge assemblies (ECAs) providing a support structure for respective BRE wires along the axis, each said first ECA including an energetic material that extends along or parallel to the axis, wherein the energetic material is configured to burn along with the solid propellent to produce thrust in the rocket motor; and
one or more initiators that are operatively coupled to the respective first ECAs to detonate the energetic material;
wherein the energetic material is configured to be capable upon detonation to break up the solid propellent to terminate thrust.
