The purpose of this legislation, known as the Sustainment of Unmanned Systems, Total Force Aircraft Inventory, and National Guard Protection Act, is to protect the operational capacity of MQ-9 aircraft units within the U.S. Air Force and Air National Guard. It aims to ensure that these units maintain their current capabilities and personnel levels, preventing any reductions that could impact their mission effectiveness. Key provisions of the law prohibit the Secretary of the Air Force from making significant changes to MQ-9 aircraft units during a specified period.
