The airlines contractually pledge aircraft to the various segments of Civil Reserve Air Fleet, ready for activation when needed. To provide incentives for civil carriers to commit aircraft to the Civil Reserve Air Fleet program and to assure the United States of adequate airlift reserves, the government makes peacetime airlift business available to civilian airlines that offer aircraft to the Civil Reserve Air Fleet. Department of Defense offers business through the International Airlift Services. For fiscal year 2005, the guaranteed portion of the contract was $418 million. Air Mobility Command (AMC) previously reported that throughout fiscal 2005 it planned to award more than $1.5 billion in additional business beyond the guaranteed portion of the contract.
