Abstract: This paper studies the chemical stability of the nitrocellulose double based propellants charges of START engine of Soviet surface-to-air missile system, S-125 "Neva" which was introduced in the armament of the Army of Serbia, in the early seventies of the last century and it is still in use. The experimental results of examinations of tested propellants by different analitycal methods, confirmed the fact that the role of the stabilizer does not perform classic organic propellant stabilizers. Therefore, the chemical stability of this unusual type of propellant had to be additionally tested by STANAG 4582 microcalorimetry method of heat flux measuring, which is not based on measuring of the consumption of stabilizer. Keywords: double-base rocket propellant, chemical stability.
