Abstract: Possible application of cast PBX explosive instead of conventional explosive charges is examined, in order to increase safety and to reduce vulnerability. Verification of the quality is done and level of the performance is tested for the chosen cast composite explosive composition HMX(73)/Al(10)/HTPB(17) in projectile 125 mm M86A1 in comparison to the conventional composition HAl-20, for the application in devastating HE artillery projectiles. In order to verify the quality of PBX explosive obtained by technological process of casting, it was laborated in the control casing to check the physico-chemical properties of the explosive charge. Insensitivity was tested performing the test of the effect of high temperatures (simulated fire conditions) and by shooting of small arms ammunition. Test of safety firing under higher pressure of powder gas was done from a cannon, for a group of projectiles charged by the examined explosive and HAl-20. A comparative evaluation of efficacy was done for the projectile 125 mm M86A1 containing pressed HAl-20 and cast PBX in the pit and arena test. Keywords: cast PBX, HAl-20, 125 mm projectile, insensitivity, testing the effectiveness, pit test, arena test.
