A high load and shock linear actuator is provided that may be used to position a hatch on a waterborne platform. The actuator includes a power-screw actuator, a manual operator, a bidirectional brake, an actuator motor, and a motor brake. The power-screw actuator is coupled to receive a drive torque from either the actuator motor or the manual operator, and is responsive to this drive torque to position the hatch. The bidirectional brake transfers manual input torque supplied to its input by the manual operator, and prevents torque supplied to its output from being transferred to its input. The actuator motor includes a stator, a rotor, a ring gear, and a differential carrier assembly. The differential carrier assembly is disposed within the rotor inner volume. The motor brake is mounted adjacent the actuator motor and selectively prevents and allows actuator motor rotation.
