Concepts and technologies described herein provide for a low noise aircraft wing slat system. According to one aspect of the disclosure provided herein, a cove-filled wing slat is used in conjunction with a moveable leading edge element of an aircraft wing to provide a high lift system. The moveable leading edge element may include a one-piece or two-piece panel that retracts within the aircraft wing to accommodate the cove-filled slat in the stowed position. Upon deployment of the cove-filled slat, the moveable leading edge element deploys outward to create a continuous outer mold line shape with the wing.
