Home of the 737

Renton, Wash.--At the south end of Lake Washington, just outside of Seattle, Boeing builds its 737 aircraft, the smallest airliner in its commercial airplane family. At present, the factory produces 31.5 737-800 and 737-900 airliners per month. By the first half of 2014, Boeing says it will increase production to 42 airplanes per month.

The Renton facility is one of Boeing's original factories in the Puget Sound Region. After beginning operations in 1941, Boeing built B-29 aircraft here during World War II. After the war, the company used the plant to build its first passenger jetliner, the 707, and later the 727, 737, and 757. Final 737 assembly now takes place in a 75,000-square-foot building that employs 9,000 people.
