Who develops the spares lists that make up the Readiness Spares Packages (RSP)?

The correct answer is that MAJCOMs (Major Commands) in conjunction with Air Force Materiel Command develop the spares lists that make up the Readiness Spares Packages (RSP). This process involves collaboration between various levels of command and specialized materiel management organizations to ensure that the spares packages are tailored to meet specific operational and maintenance needs of the Air Force's fleet of aircraft and equipment.

MAJCOMs are responsible for the strategic management and oversight of their respective missions, including logistics operations. They work closely with Air Force Materiel Command, which focuses on the development, procurement, and sustainment of weapon systems and their associated supplies. Together, they analyze operational requirements, maintenance practices, and historical data to determine what spare parts are essential for readiness, ultimately leading to the creation of well-structured spares lists that support mission readiness.

The involvement of both MAJCOMs and Air Force Materiel Command ensures that the spares packages align with operational goals and sustainment strategies, helping to maintain aircraft availability and effectiveness in fulfilling Air Force missions.
