The 9 Countries Supplying Major Structural Components For The Boeing 787 Dreamliner Assembly Line
The 9 Countries Supplying Major Structural Components For The Boeing 787 Dreamliner Assembly Line highlights how Boeing’s 787 integrates parts built across a global network. While final assembly takes place in the United States, Boeing distributes more design and production to international suppliers than in prior commercial aircraft programs. The supply chain involves more than 50 major companies delivering completed fuselage sections, wings, and tail components to U.S. sites such as Everett and North Charleston. The article says Japan alone supplies about 35% of the 787’s airframe structure, making it the largest outside-U.S. contributor. It details Japanese firms’ roles: Mitsubishi Heavy Industries for wing boxes, Kawasaki Heavy Industries for forward fuselage sections 43 and 44, plus the main landing gear wheel well and fixed trailing edge, and Subaru Corporation for the center wing box linking the wings and carrying primary bending loads. The program, launched in 2004, uses risk-sharing arrangements with Japanese partners rather than traditional subcontracting, tied to long-term customer relationships.
