# USAF Advocates Updating Aircraft Inventory Metric

The U.S. Air Force is advocating for a revision of its fighter aircraft inventory measurement from the traditional Primary Mission Aircraft Inventory to a more comprehensive Combat Coded Total Aircraft Inventory. This updated metric would include backup and attrition reserve aircraft, providing a more accurate reflection of combat readiness. The change aims to align funding and force sizing with current operational demands and national defense strategies, potentially influencing future procurement priorities and budget allocations for aircraft acquisition and sustainment.

- Procurement professionals should anticipate shifts in contract requirements reflecting increased emphasis on reserve and backup aircraft capabilities.
- This metric update signals potential growth in demand for aircraft maintenance, modernization, and acquisition contracts to support a larger effective combat fleet.
- Contractors specializing in fighter aircraft systems and sustainment may find new opportunities as the Air Force seeks to enhance overall readiness.
- Budget planners and acquisition officials should consider the implications of revised readiness metrics on funding requests and program justifications.
