The precise prediction of ballistic missile trajectories is critical to the operational efficacy. Nevertheless, a ballistic missile's trajectory remains vulnerable to various external disturbances or internal malfunctions that could lead to deviations from the intended flight. Comprehensive analyses of missile performance in failure scenarios are necessary to solve these issues. This study employs a 200 mm caliber missile, fitted with canards specifically engineered to manage body dynamics and perform trajectory correction tasks. The canards are arranged in a cruciform configuration. This research presents a comprehensive analysis of a 6-degree-of-freedom (6 DOF) simulation model designed to predict the dynamic flight behavior of a rocket in the event of canard failures. The research investigates how canard failures affect trajectory deviations, taking into account situations in which canard fins 1, 2, and 3 malfunction. The research investigates how these failures affect critical flight parameters. Notably, results show that the trajectory exhibits a large divergence, with characteristics like the maximum impact point deviation reaching up to 1.63 km, in the configuration where all three canard fins fail. On the other hand, when two canard fins fail, the highest side deviation that is seen is much smaller, about 15 m.
