At 65,000 cubic feet (1,840 cubic meters) the cargo hold is the largest in the world for an aircraft . It can hold three times the volume of a 747 - 400F freighter . Cargo is placed in the aircraft by the world's longest cargo loader . It is an extensively modified Boeing 747 - 400 that is used exclusively for transporting Boeing 787 Dreamliner aircraft components to Boeing's assembly plants from suppliers around the world . </P> <P> Boeing Commercial Airplanes announced on October 13, 2003 that, due to the length of time required by land and marine shipping, air transport will be the primary method of transporting parts for the assembly of the Boeing 787 Dreamliner (then known as the 7E7). Boeing 787 parts were deemed too large for standard marine shipping containers as well as the Boeing 747 - 400F, Antonov An - 124 and Antonov An - 225 . Initially, three used passenger 747 - 400 aircraft were to be converted into an outsize configuration in order to ferry sub-assemblies from Japan and Italy to North Charleston, South Carolina, and then to Washington state for final assembly, but a fourth was subsequently added to the program . The Large Cargo Freighter has a bulging fuselage similar in concept to the Super Guppy and Airbus A300 - 600ST Beluga outsize cargo aircraft, which are also used for transporting wings and fuselage sections . </P>
