This study determines the increase in the kinematic performance and lethality of a generic Short-Range Air-to-Air Missile (SRAAM) due to the introduction of Dual-Interrupted-Thrust (DIT) technology to the missile motor. Data for this study was collected using-.the U.S. Air Force Trajectory Analysis Program (TRAP). The SRAAM modelled was similar in capability to the AIM-9 Sidewinder currently in U.S. and Canadian Forces (CF) inventories. Quantification of kinematic performance was based on Performance Indices (PIs) which took into account range and time of flight constrained by a maximum miss distance (the lethal radius of the warhead) for seven selected scenarios. Comparison of missile lethality was based on the ratios of the distances between the outer and inner launch boundaries for the generic and modified SRAAMs. The results showed that DIT technology improves the kinematic performance and lethality of a SRAAM, provided the missile is not seeker limited , i.e. the lethality benefits are greatest for rear aspect and shoot-up engagements.
