Civil Reserve Air Fleet The Civil Reserve Air Fleet is part of the United States ' s mobility resources . Selected aircraft from U . S . airlines , contractually committed to Civil Reserve Air Fleet , support United States Department of Defense airlift requirements in emergencies when the need for airlift exceeds the capability of military aircraft . Background . In 1952 , after aircraft were commandeer ed for the Berlin Airlift , CRAF was created as a more orderly way of serving emergency military needs . The Fleet has three main segments : international , national and aeromedical evacuation . The international segment is further divided into the long - range and short - range sections and the national segment into the domestic and Alaskan sections . Assignment of aircraft to a segment depends on the nature of the requirement and the performance characteristics needed . The long - range international section consists of passenger and cargo aircraft capable of transoceanic operations . The role of these aircraft is to augment the Air Mobility Command ' s long - range intertheater C - 5 s and C - 17 s during periods of increased airlift needs , from minor contingencies up through full national defense emergencies . Medium - sized passenger and cargo aircraft make up the short - range international section supporting near offshore airlift requirements . The aircraft in the Alaskan section provide airlift within U . S . Pacific Command ' s area of responsibility , specific to Alaska needs . The domestic section is designed to satisfy increased DoD airlift requirements in the U . S . during an emergency . The aeromedical evacuation segment assists in the evacuation of casualties from operational theaters to hospitals in the continental United States . These aircraft are also used to return medical supplies and medical crews to the theater of operations . Kits containing litter stanchions , litters and other aeromedical equipment are used to convert civil Boeing 767 passenger aircraft into air ambulances . Membership commitment and requirements . 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 . To join Civil Reserve Air Fleet , carriers must maintain a minimum commitment of 30 percent of its Civil Reserve Air Fleet capable passenger fleet and 15 percent of its Civil Reserve Air Fleet capable cargo fleet . Aircraft committed must be U . S . registered and carriers must also commit and maintain at least four complete crews for each aircraft . Carriers with aircraft whose performance does not meet minimum Civil Reserve Air Fleet requirements are issued a certificate of technical ineligibility so they can still compete for government airlift business . Aviation safety is the paramount concern , and numerous procedures are in effect to ensure that the air carriers with which AMC contracts afford the highest level of safety to Department of Defense passengers . Prior to receiving a contract , all carriers must demonstrate that they have provided substantially equivalent and comparable commercial service for one year before submitting their offer to fly for the Department of Defense . All carriers must be fully certified Federal Aviation Administration carriers and meet the stringent standards of Federal Aviation Regulations pertaining to commercial airlines ( Part 121 ) . A Department of Defense survey team , composed of experienced AMC pilots and skilled aircraft maintenance personnel , performs an on - site inspection of the carriers . This team conducts a comprehensive inspection that includes carrier ' s aircraft , training facilities , crew qualifications , maintenance procedures , quality control practices and financial status to maximize the likelihood that the carrier would safely perform for Department of Defense . After passing this survey , the carrier is certified by the Commercial Airlift Review Board as DOD - approved before receiving a contract . AMC analysts then continue to monitor the carrier ' s safety record , operations and maintenance status , contract performance , financial condition and management initiatives , summarizing significant trends in a comprehensive review every six months . In addition to this in - depth review , there are several other surveillance initiatives . These include safety preflight inspections of commercial aircraft by Department of Defense designated inspectors , periodic cockpit observations on operational flights by highly experienced pilots from AMC ' s Department of Defense Commercial Airlift Division , and an increase in the frequency of on - site surveys . These initiatives and the surveys are further supplemented by an open flow of information on all contract carriers between AMC and the FAA through established liaison officers . Fleet . As of May 2007 , 37 carriers and 1 , 364 aircraft were enrolled in the CRAF . This includes 1 , 273 aircraft in the international segment ( 990 in the long - range international section and 283 in the short - range international section ) , and 37 and 50 aircraft , respectively , in the national and aeromedical evacuation segments , and four aircraft in the Alaskan segment . These numbers tend to fluctuate on a monthly basis . Activation . Three stages of incremental activation allow for tailoring an airlift force suitable for the contingency at hand . Stage I is for minor regional crises , Stage II would be used for major theater war and Stage III for periods of national mobilization . The commander , U . S . Transportation Command , with approval of the secretary of defense , is the activation authority for all three stages of Civil Reserve Air Fleet . During a crisis , if AMC has a need for additional aircraft , it would request the commander of USTRANSCOM to take steps to activate the appropriate Civil Reserve Air Fleet stage . Each stage of the Civil Reserve Air Fleet activation is only used to the extent necessary to provide the amount of civil augmentation airlift needed by Department of Defense . When notified of call - up , the carrier response time to have its aircraft ready for a Civil Reserve Air Fleet mission is 24 to 48 hours after the mission is assigned by AMC . The air carriers continue to operate and maintain the aircraft with their resources ; however , AMC controls the aircraft missions . CRAF has been activated once as part of Operation Desert Shield and once as part of Operation Iraqi Freedom . Membership .
