The system includes a rotary turret platform for aiming of a high power laser beam. The system further includes a turret payload device coupled to the rotary turret platform. The system further includes an off-axis telescope coupled to the turret payload, having an articulated secondary mirror for correcting optical aberrations, and configured to reflect the high power laser beam to a target through a first of at least two conformal windows. The system further includes an illuminator beam device configured to actively illuminating the target to generate a return aberrated wavefront through the first of the at least two conformal windows. The system further includes a coarse tracker coupled to the turret payload, positioned parallel to and on an axis of revolution of the off-axis telescope, and configured to detect, acquire, and track the target through the second of the at least two conformal windows.
