What feature does the tail actuated system (TAS) include?

The tail actuated system (TAS) encompasses several critical components that work together to enhance the performance and maneuverability of the system. Each of these features plays an essential role in ensuring that the TAS functions effectively during operation.

The inclusion of four moving fins is significant because these fins allow for precise control and adjustment of the system's trajectory and stability in flight. This feature enables the system to respond quickly to dynamic conditions, ensuring better navigation and accuracy.

The mission computer is another key component as it processes data and executes commands to manage the system’s operations. This computer integrates information from various sensors and systems, facilitating real-time decision-making that is crucial for mission success.

Additionally, having a GPS antenna positioned on the aft (rear part) is vital for the system to receive accurate positioning and navigational data. This capability allows for better situational awareness and ensures that the system can track its intended path effectively.

Together, these components form a comprehensive system that maximizes the operational capacity of the TAS, demonstrating how each feature contributes to its overall functionality and mission effectiveness. Having all these elements working in unison is why the correct answer reflects that all of the mentioned features are included in the tail actuated system.
