Abstract

The present disclosure relates to the passive initiation and release of incident energy-dissipating material from locations on an incident energy target surface as a counter measure response for the protection of a platform. The response is activated over a predetermined area or areas on an incident energy target surface in response to an incident directed energy sensed on a target surface.
