Abstract: his paper deals with several flying ballistic anomalies in the targetpractice for some types of ground-to-air missiles. The internal ballistic anomalies insolid rocket motors (SRM ), having been in term of service for many years, are analysed in respect to ageing of double base propellant grain, adjustment of nozzlethroat area, mass ejection and crack burning, which will be great helpful in the employment and maintenance of SRM during the term of service as well as the targetpractice.

Key words: Solid propellant rocket motor;Interior ballistic performance;Double base propellant;Fault analysis.
