Northrop and Grumman merged in 1994, joining a stealth aircraft pioneer with the builder of the Apollo lunar module. The B-21 Raider bomber and the Sentinel intercontinental ballistic missile modernization are the largest programs, both fixed-price or cost-sensitive enough that execution risk has affected earnings. Space systems grew substantially through the 2018 Orbital ATK acquisition, adding launch vehicles and solid rocket motors. Nearly all revenue comes from the United States government, and headquarters are in Falls Church, Virginia.
