This is a Request for Information (RFI) to inform a congressional report on future large and oversized air cargo transportation services. The U.S. Transportation Command seeks information on a civilian aircraft currently under development that could carry cargo up to 300 feet long, such as space launch vehicles. The aircraft must be capable of entering service no later than December 31, 2035. The required service period would be for 2 to 5 years, providing between 2,000 and 7,500 flight hours beginning when the aircraft enters service. No budget or specific performance location is detailed in this RFI.
