Primary Commercial Jet Assembly Plants in the United States
Boeing commercial airplanes are primarily built in large, purpose-built assembly facilities in the United States. The main final assembly lines for wide-body and narrow-body jets operate in Washington state and South Carolina, supported by a network of engineering, manufacturing, and supplier locations. The two principal U.S. assembly sites are the Renton Factory in Washington, which produces the 737 family, and the North Charleston Factory in South Carolina, which assembles the 787 Dreamliner and 777X models. Additional major work occurs in Everett, Washington, where the 747 and 777 families complete final assembly before delivery.
Key Boeing U.S. Assembly Facilities and Products
Each major facility specializes in certain families of aircraft, leveraging local infrastructure, workforce skills, and long-standing production systems. The campuses integrate final assembly, painting, flight testing, and delivery operations, while earlier manufacturing steps such as machining and composite fabrication often occur at additional regional sites. Understanding which airplanes are produced where helps explain logistics, supplier relationships, and workforce distribution across the company’s footprint.
Renton Factory, Renton, Washington
The Renton Factory focuses on 737 family narrow-body airplanes. Boeing acquired this site decades ago and has progressively expanded its structures and automated systems to keep pace with production demand. Aircraft move through fuselage integration, wing attachment, painting, and flight-line testing before being delivered to customers.
Everett Factory, Everett, Washington
Everett hosts final assembly for both the 767 and 777 families, including the latest 777X variants. The campus features some of the world’s largest covered manufacturing spaces, enabling the precise joining and systems integration required for wide-body jets. Completed aircraft perform test flights nearby before customer acceptance and delivery.
North Charleston Factory, North Charleston, South Carolina
Opened in the early 2010s, this facility produces the 787 Dreamliner and 777X airplanes. Its design incorporates modern production techniques and collaborative workspaces to support complex wiring, composite structures, and systems integration. The site also performs painting and delivery operations for these wide-body models.
Global Production Network and Supplier Engagement
While final assembly occurs at the above U.S. campuses, Boeing relies on an extensive network of suppliers across dozens of countries for components, systems, and major subassemblies. Commercial airplanes are the result of a highly coordinated global effort, with wings, avionics, interiors, and other major modules often built in one region and transported to assembly lines elsewhere. This distributed model shapes lead times, logistics planning, and the overall status of each program.
Production Status and Delivery Metrics by Site
The table below summarizes the relationship between primary facilities, core airplane families produced, and publicly reported metrics such as monthly output and program status as of recent quarters. Exact figures fluctuate with production planning, customer demand, and operational conditions.
| Facility | Airplanes Produced | Typical Monthly Output (recent) | Program Status | Source Context |
|---|---|---|---|---|
| Renton, Washington | 737 family | 38–42 aircraft | In production at multiple lines | Company production reports, public filings |
| Everett, Washington | 767, 777, 777X | 6–9 aircraft | In production, 777X deliveries ongoing | Company production reports, public filings |
| North Charleston, South Carolina | 787, 777X | 1–3 aircraft | In production, ramping with 777X | Company production reports, public filings |
Delivery Logistics and Customer Locations
After rolling off the assembly line, airplanes undergo final checks, receive customer-specific configurations, and are ferried to delivery airports. Ferry flights route through key hubs, with logistics teams selecting paths that optimize fuel efficiency, slot availability, and weather conditions. Customers can track the status of their airplanes through Boeing production and delivery dashboards, which provide visibility into where each airplane is in the flow from factory to operator.
Design, Engineering, and Long-Term Planning
Design and systems engineering for Boeing commercial jets occur at multiple sites, including locations near Seattle and in the Carolinas, enabling continuous collaboration with suppliers and customers. Engineering teams coordinate with manufacturing operations to integrate new technologies, update production tooling, and plan future model improvements. Decisions about new assembly lines, expansions, or shifts in production mix are typically driven by long-term demand forecasts, supplier capabilities, and strategic portfolio considerations rather than short-term disruptions.
