Boeing employees joined with community leaders from across the region to celebrate the grand opening of its new 777X Composite Wing Center (CWC) at the Everett, Wash., campus. 

Boeing has invested more than $1 billion in the Everett site for construction and outfitting of the new building.

The facility will manufacture the world’s largest composite wings for the 777X, the company's newest commercial jetliner and sustain thousands of local jobs for decades to come.

Construction of the new CWC building required approximately 4.2 million hours of construction time. At its peak, 1,700 contract employees worked on the project. The CWC is more than 27 acres under one roof – the equivalent to 25 football fields. It will contain three of the world’s largest autoclaves. Each will be big enough to fit two 737 fuselages inside.

To date, the 777X has accumulated 320 orders and commitments. Two models will comprise the 777X family – the 777-8X, with approximately 350 seats and a range capability of more than 9,300 nautical miles; and the 777-9X, with approximately 400 seats and a range of more than 8,200 nautical miles. First delivery of the 777X is targeted for 2020.
