"Boeing manufactures the 787's tail fin at its plant in Frederickson, Washington, the ailerons and flaps at Boeing AUSTRALIA, and fairings at Boeing CANADATechnology. For its entire history, Boeing has guarded its techniques for designing and mass producing commercial jetliner wings. For economic reasons, the wings are manufactured by JAPANESE companies in Nagoya, e.g. Mitsubishi Heavy Industries; the horizontal stabilizers are manufactured by Alenia Aeronautica in ITALY; and the fuselage sections by Vought in Charleston, SOUTH CAROLINA (USA), Alenia in Italy, Kawasaki Heavy Industries in Japan and Spirit AeroSystems, in Wichita, Kansas (USA). The passenger doors are made by Latecoere (FRANCE)and the cargo doors, access doors and crew escape door are made by Saab(SWEDEN). Japanese industrial participation is very important to the project, with 35% work share, with many of the subcontractors supported and funded by the Japanese government.[49] "
