ABSTRACT
This article covers trend of modernization of existing, 'the old' artillery rocket systems. The method is explained and presented together with comprehensive data for the one of most known MBRL weapon system - the BM-21 'Grad The particular consideration of propellant grain substitution process as driving force of this modernization is made. The varieties of this substitution are presented, each variation has certain and graduated impact of rocket performances, integration complicity, and production costs. The User can govern this propellant grain substitution process from simple propellant grain refilling in existing rocket's hardware with keeping same tactical data or improve them through modification and replacement sonic parts of rocket motor and fins, beside mandatory propellant grain substitution. By proper design it is possible make these variations of upgrading as interchangeable. Cast composite rocket propellants are chose, as most versatile and technological kind of solid rocket propellants. Their production is can be easily established and upgraded if it is needed. Demilitarization of existing colloidal (double base) propellant grain into the energetic materials with commercial value is suggested instead simple, danger, useless, and expensive open burn method.
