EVERETT, Wash. - Boeing's plans to assemble that stretched 787-10 model, currently in development, exclusively at its facility in North Charleston, S.C.

The 787-8 and 787-9 are currently assembled in the program's Everett, Wash., and North Charleston facilities. Design of the 787-10 is underway in Everett, with final assembly of the first 787-10 scheduled to begin in South Carolina in 2017.

"We looked at all our options and found the most efficient and effective solution is to build the 787-10 at Boeing South Carolina," said Larry Loftis, vice president and general manager, 787 program, Boeing Commercial Airplanes. "This will allow us to balance 787 production across the North Charleston and Everett sites as we increase production rates. We're happy with our growth and success in South Carolina, and the continued success at both sites gives us confidence in our plan going forward."

The 787-10 will be 18 feet (5.5 meters) longer than the 787-9. With 10 feet (3 meters) of that increase in the midbody section, the 787-10 midbody is too long to be transported efficiently from North Charleston, where systems integration work is performed, to the Everett facility for final assembly. In addition, introducing the 787-10 in North Charleston takes advantage of that facility's capacity while allowing the Everett facility to continue improving productivity as it focuses on the 787-8 and 787-9.

The 787 production system includes three production lines: two in Everett (including a temporary surge line) and one in South Carolina. The integrated production system currently operates at a production rate of 10 airplanes per month. As announced last year, the 787 production rate will increase to 12 airplanes per month in 2016 and 14 per month by the end of the decade.

The Everett facility will continue to assemble seven airplanes per month, while Boeing South Carolina final assembly will gradually increase from three 787s per month today to five per month in 2016 and seven per month by the end of the decade.

Since its launch in June 2013, the 787-10 has won 132 orders from six global customers.
