Company Overview

Northrop Grumman is one of the largest U.S. defense contractors, headquartered in Falls Church, Virginia, with about 95,000 employees and more than 550 facilities. Unlike Boeing or Airbus, it has no commercial aircraft business. Its work centers on strategic and high-technology systems: the B-21 Raider bomber, the Sentinel ICBM, satellites and space hardware such as the James Webb Space Telescope, radars and sensors, and missile-defense networks. A large share of its work sits in classified "restricted" programs, which accounted for $14.8 billion of new awards in 2025. Northrop Grumman traces its origins to Northrop Aircraft founded in 1939 in Hawthorne, California, by Jack Northrop, and Grumman Aircraft Engineering founded in 1929 in Baldwin, New York, by Leroy Grumman; the two aerospace pioneers merged in 1994 to create the modern global defense conglomerate headquartered in Falls Church, Virginia.

Legacy

Challenges & Strategic Context

The main risks are cost execution on fixed-price programs (the B-21 low-rate production lots have already produced loss charges), the restructured and costlier Sentinel ICBM program, U.S. budget and continuing-resolution timing, supply-chain constraints in rocket motors and microelectronics, and losing new franchise competitions, such as the Navy F/A-XX fighter awarded to Boeing in September 2026.
