Which department checks and manages aircraft modes?

The STRIKE Department is responsible for managing and checking aircraft modes because it is directly involved in the planning and execution of air operations, including the coordination of aircraft launches and recoveries. This department also oversees the tactical application of aircraft capabilities during missions. By ensuring that aircraft are set to the appropriate modes for their intended missions—such as combat, reconnaissance, or surveillance—the STRIKE Department plays a crucial role in operational effectiveness.

The other departments have specific functions that do not primarily include managing aircraft modes. For instance, the ASW Department focuses on anti-submarine warfare tactics and strategies, while the Navigation Department is concerned with ensuring safe and effective navigation of the vessel. The Operations Department handles broader operational strategies but does not specialize in the technical aspects of aircraft modes. Therefore, the STRIKE Department is the most appropriate choice for this responsibility within military operations involving aircraft.
