Northrop Grumman moved the the 157-acre Pico Rivera facility, located at the corner of Rosemead and Washington boulevards, in 1982. The Pico Rivera site is located approximately 1.5 miles from the 605 and 5 Freeways. The the primary facility for the B-2 stealth bomber program, employment at the site peaked at about 13,000 in the early 1990's. By 1997 Northrop Grumman personnel at Pico Rivera performed several important program functions including engineering design, composite component manufacturing, and integrated logistics support. In addition, they were executing the B-2 multistage improvement program, which provides the research, development, and testing necessary for enhancements to the B-2 throughout its operational life.
The company subsequently moved B-2 operations to the Air Force Plant 42 in Palmdale, CA and other locations. In January 2000 Northrop Grumman's Integrated Systems and Aerostructures (ISA) sector dedicated a major expansion of the engineering software development and maintenance test labs at Tinker AFB for the B-2 stealth bomber. The 56,000-square-foot addition more than tripled the laboratory space of the B-2 Weapons Systems Support Center (WSSC) and facilitated the transition of the remaining labs from Northrop Grumman's ISA Air Combat Systems facility in Southern California. The WSSC's mission - maintaining, developing, testing and integrating all flight program software in support of the operational B-2 fleet at Whiteman AFB - is a significant one. Each B-2 has 134 computers that help the pilots manage the aircraft and its systems, and more than two million lines of code are used to manage these onboard computers. Under a partnership between the Air Force and the company, the WSSC maintains, integrates and tests software in support of the operational B-2 fleet at Whiteman AFB, MO. The labs were developed and built by Northrop Grumman in cooperation with key system suppliers on the B-2. Twelve labs had been moved to the WSSC from the company's Air Combat Systems facility in Pico Rivera by early 2000, at which time three labs remained to be transferred.
In January 2000 Northrop Grumman's Integrated Systems and Aerostructures (ISA) sector and Hill AFB dedicated a new facility to serve as the composite manufacturing and repair center for the B-2 stealth bomber. Work began the following month on flight control surfaces and other B-2 composites components. Northrop Grumman ISA's Air Combat Systems business area had been working under a teaming agreement to help train U.S. Air Force technicians in the manufacturing and repairing of advanced composite structures on the B-2. The company also was transferring composite manufacturing equipment during the previous year to Hill AFB from its Air Combat Systems facility in Pico Rivera. This effort allowed Hill AFB to serve as the repair depot for all B-2 composite structures.
By mid-2000 the company employed about 1,500 people on the B-2 program, most of them at the Palmdale facility. In July 2000 Northrop Grumman and the Sares-Regis Group of Irvine signed a sales agreement for Northrop Grumman's property in Pico Rivera.
Northrop Grumman vacated the Pico Rivera site in September 2000. On 26 September 2000 US Commerce Secretary Norman Y. Mineta announced the award of a $1.9 million Economic Development Administration (EDA) grant to the city of Pico Rivera, California, to aid in the construction of infrastructure improvements needed to boost the industrial, commercial, and manufacturing reuse of the Northrop/Grumman defense plant property.
The new new Advanced Systems Development Center (ASDC) in El Segundo houses approximately 500 employees along with laboratories and other technical facilities formerly located at other Northrop Grumman sites in Pico Rivera, El Segundo and Hawthorne, Calif.
