There was a manufacturing facility located at the corner of Rosemead and Washington boulevards, which was owned and operated by the Ford Motor Company called Los Angeles Assembly. The plant opened in 1958 and closed in 1980 and was purchased by Northrop Grumman in 1982 for its Advanced Systems Division. Upon the unveiling of the B-2 Spirit bomber in 1988, it was revealed that much of the development for the former black project had in fact occurred at the site. In the early 1990s, the division was renamed the B-2 Division to reflect its most famous product. At its peak, the project employed approximately 13,000 workers in Pico Rivera. The site was closed and then demolished in 2001 partially due to air quality remediation efforts, and is now a large retail center.
