Abstract : A feasibility study was initiated by the Air Force to investigate the possibility of mounting the 40mm XM75 Launcher in a pod on a fixed wing aircraft. This increased the velocity of the firing platform from which the launcher must operate to 300 knots from the helicopter velocity of 140 knots. Although the XM385 Projectile has been successfully fired at 225 knots, a question was raised concerning the stability of the round at 300 knots. Because of the possibility of instability existing and the data available being insufficient to arrive at a definite conclusion, Picatinny Arsenal conducted a study of the XM385 Projectile's characteristics.
