Abstract: Embodiments relate to a projectile system, method and computer program product for controlling the flight of a projectile to make a course change by approximately 90°, greater than 90° or up to 90°. The projectile system comprises a gun-fired projectile having a body, at least one tail fin, a motor firing during a first flight phase and during a second flight phase and at least one controllable canard. The projectile system includes one or more processors configured to determine a turn maneuver profile to a target during the first flight phase, produce control signals to destabilize the body, create a pitch attitude change for the turn maneuver profile and effectuate a turn of the projectile in a direction corresponding to the turn maneuver profile during the first flight phase. The processors control the motor to start the second flight phase to the target after the turn.
