Thermal radiation simulation units were developed and fielded on the MILL RACE event. The units released over 1 billion calories of radiant energy at a peak power rate of 1.4 x 10 to the 9th power watts. The units were fired in conjunction with the 600 ton MILL RACE event to produce blast and thermal radiation loadings on a variety of structures.
