What is used to move the control surfaces on the AFT end of the AGM-65 Maverick?

The correct answer involves understanding the operational mechanics of the AGM-65 Maverick missile. The control surfaces on the aft end of the Maverick are primarily moved using a system that incorporates either High-Pressure Airborne Systems (HAS) or Pneumatic Actuator Systems (PAS). These systems are designed to provide the necessary force to actuate the control surfaces, allowing for precise maneuverability during flight. This is crucial for the missile to navigate effectively towards its target.

In contrast, the GPS Guidance System is responsible for navigation but does not directly control the movement of the control surfaces. The Hydraulic Actuator is often utilized in various applications for actuation purposes but is not specified for the Maverick in this context. Mechanical Linkage might contribute to the control surface movement in some systems, but in the case of the AGM-65, the use of HAS or PAS systems is definitive. Therefore, understanding the specific technologies used in the AGM-65 Maverick missile is key to recognizing why the chosen answer is the most accurate.
