FSC 23 is primarily classified for which of the following equipment?

FSC 23, or Federal Supply Classification 23, is specifically designated for Ground Effect Vehicles, which are capable of sustained flight and operate close to the surface of the ground. This classification is used to categorize equipment that utilizes the aerodynamic principles of ground effect to enhance lift and efficiency during flight. Ground Effect Vehicles can encompass a variety of craft, including hovercraft and certain types of amphibious vehicles, which rely on a cushion of air created by their proximity to the surface to achieve flight or movement.

Understanding this classification is crucial for effective logistics management since it allows personnel to accurately identify, procure, and maintain the unique requirements associated with these vehicles. In contrast, the other categories—aircraft components, machinery systems, and transport equipment—serve distinct functions and have separate classification systems, thus not aligning with the specific designation of FSC 23.
