Abstract : In order to correctly predict the missile flight dynamics and the impact point of missile, the�accuracy of aerodynamic coefficient prediction is key. Traditionally, those coefficients were�predicted using semi-empirical and Experimental Fluid Dynamics (EFD). However, the former�cannot offer sufficient fidelity predict and the latter is increasingly expensive.�Therefore, Defense Technology Institute (DTI) is initiating application and integration of�the alternative approach, Computational Fluid Dynamics (CFD), in the Trajectory Prediction. To�trustfully apply CFD as the design tool in Trajectory prediction, the benchmark CFD simulation�against generally accepted experiment is the significant fist step.�The present paper thus investigate accuracy of CFD prediction for the projectile flow field�using Steady Reynolds-Averaged Navier-Stokes (SRANS) equations with first-order (realizable k-
