An unassembled hydraulic stabilator actuator from an F-15E Strike Eagle is prepared for reassembly on a work bench at Seymour Johnson Air Force Base, North Carolina, Jan. 7, 2021. The hydraulic actuator, which moves the stabilator of an F-15E, defects collectively for pitch control and differentially to add roll control power to the jet ailerons.
