Which function is NOT a responsibility of the Tanker Planning Cell?

The function that is not a responsibility of the Tanker Planning Cell is the planning and execution of SEAD (Suppression of Enemy Air Defenses) missions. The primary focus of the Tanker Planning Cell is to manage aerial refueling operations, which encompasses coordinating tanker aircraft allocation, establishing ground and airborne alert air refueling (AR) requirements, and constructing and coordinating airspace to support tanker missions.

SEAD missions, however, involve tactics aimed at neutralizing or destroying enemy air defenses, which falls under the purview of different operational cells or units focused on offensive air operations rather than the logistics of aerial refueling. This distinction highlights the specialized roles within combat planning, ensuring that each cell concentrates on its designated functions for optimal mission effectiveness.
