It also known as the Boeing 747-400 Large Carg o Freighter (LCF). With a volume of 65,000 cubic feet (1,840 m³) the Dreamlifter can hold three times that of a 747-400F freighter. It is used primarily for transporting Boeing 787 Dreamliner aircraft components to Boeing's assembly plants from suppliers around the world. 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. Of the four 747 Dreamlifters Boeing acquired, three were complete and operational by June 2008, and the fourth became operational in February 2010. On July 1, 2020, a Dreamlifter arrived at Salt Lake City International Airport, carrying 500,000 face masks to be used by Utah school children and teachers as part of the state's response to the Coronavirus disease 2019 pandemic. The flight was a joint effort between Boeing, Atlas Air, H.M. Cole, Cotopaxi, Flexport, UPS and the state of Utah. For more information, click here.
