Boeing is planning to consolidate its defence and space business by the end of 2020, in a bid to improve its operating efficiency.
The company will also move more than 1,600 jobs from its Huntington Beach facility to Los Angeles County over the next four years.
Boeing's St. Louis and Huntsville's sites will receive more than 900 jobs.
Employees will be relocated to facilities in El Segundo, Long Beach, and Seal Beach in Southern California, while jobs in Kent, Washington will be moved to nearby Tukwila.
Boeing Defense, Space & Security president and CEO Leanne Caret said: “In order to push ourselves farther and win more business, we need to make the most of our resources and talent.
“These steps will help us be a stronger partner for our customers worldwide.”
Boeing will reduce space in its facilities by approximately 4.5 million ft², as well as shut down locations in El Paso, Texas, and Newington, Virginia.
Caret further added: “Making better use of our facilities will enhance efficiency and promote greater collaboration.
“This will help drive our global growth in Boeing’s second century.”
Boeing Defence Australia, Boeing Defense Saudi Arabia and Boeing Defence United Kingdom will become a part of a new global operations group led by David Pitchforth.
