The requirement for increased airlift capability is now documented in the Hq. Military Airlift Command Statement of Operational Need. Many studies were conducted to investigate the alternative solutions proposed to meet this need, both in terms of operational concepts and unconventional fuels and configuration. Preliminary results indicate that a joint Civil/Military transport aircraft of conventional configuration and fuel is the most cost effective means to satisfy the increased airlift need. Maximum utilization of advanced technology and government/industry cooperation will be required to achieve the economic incentives necessary to successfully accomplish this joint aircraft program.
