NORTH CHARLESTON, S.C. — A massive, high-tech aircraft integration and assembly facility for a major portion of the new Boeing 787 Dreamliner passenger jet formally opened its doors on Tuesday.

The Global Aeronautica facility is a joint venture between Alenia North America and Vought Aircraft Industries. Some 100 people work at the plant, and that number is expected to increase to 350.

Covering 334,000 square feet, the facility is located on a 240-acre site near Charleston International Airport.

Workers at the plant will assemble, integrate, test and apply surface finishes to more than 60 percent of each Boeing 787 fuselage. The fuselages will be shipped to Boeing’s facility in Everett, Wash., for final assembly.
