JA2 Propellants, made by non-solvent process, are of great interest for the tank gun propellant. This is due to high energy. The grain geometries of JA2 and modified JA2 propellant were designed for application to 105mm APFSDS projectile. The combustion, thermochemical, and interior ballistic properties of the propellant were tested and calculated. The performances of the propellant were evaluated out using 105mm slug T2 projectiles and 105mm tank gun. The muzzle velocity of the propellants was higher than that of the KM30 for K274 projectile.

To develop a gun propellant composition with high insensitivity and high energy, we formulated a composition by adding RDX into the nitrocellulose(NC) based propellant. The flame temperature of the RDX added NC(RAN) propellant was higher than that of neat NC propellant. The kinetic muzzle energy of RAN propellant was close to that of JA2 propellant at room temperature($21^{\circ}C$). The difference of kinetic muzzle energy of RAN propellant between high and room temperature settings as well as between a low and room temperature settings were less compared to those of JA2 propellant.
