A method of achieving an ultrahigh-burning rate composite solid propellant through the embedment of the solid explosive diazodinitrophenol (e.g., 2-diazo-4,6-dinitrophenol) having predetermined shapes and dimensions of cubes or pellets. Cubes having dimension from about 1/16 inch to about 3/32 inches on each side and pellets having dimensions from about 1/16 inch to about 3/32 inch diameters are employed in weight percent ranging from about 1 to about 5 with an uncured composite solid propellant composition in a weight percent range from about 95 to about 99. After being uniformly blended in the uncured state, the propellant and solid explosive are cured to a solid grain which has an increase in burning rate with about a 4.5 weight percent concentration of diazodinitrophenol of about 4.5 composite solid propellant composition with 0% diazodinitrophenol burned at 0.6 inches per second. A typical composite solid propellant composition has a range of hydroxy-terminated polybutadiene binder with an added polyisocyanate curative of about 1 weight percent from about 9 to about 12 weight percent, a range of ammonium perchlorate oxidizer from about 65 to about 78 weight percent, and a range of aluminum metal fuel from about 10 to about 20 weight percent.
