How many USAF loadmasters are required in a C-17?

In a C-17 Globemaster III, only one USAF loadmaster is required for operations. The loadmaster is responsible for overseeing cargo loading, securing, and managing the entire airlift mission's logistics. This single loadmaster handles a wide range of tasks including weight and balance calculations, ensuring that cargo is correctly loaded and secured to maintain aircraft stability and safety during flight.

The operational procedures and the capabilities of the C-17 allow for efficient management by one loadmaster, who is trained to handle various cargo types and methodologies. While additional loadmasters may be present during particularly large or complex operations for safety or training purposes, the standard requirement is one. This efficiency is vital to the C-17's versatile airlift mission profile, allowing rapid deployment and recovery of forces and supplies when necessary.
