A high energy, e.g., ultraviolet (UV) catalyzed decomposing foam encapsulating kinetic media forms a payload to be boosted in space and provides an ultra-light weight means for intercepting an incoming missile or other target. The decomposed foam releases the kinetic media (at designed rates so as to preserve a required density of media on target) to intercept a target and destroy it. The use of the decomposing foam significantly lowers the weight and cost and improves the probability of success of destroying the target.
