History and Development

Northrop Grumman Corporation was formed in 1994 through the merger of Northrop Corporation and Grumman Corporation, two longstanding U.S. aerospace and defense companies whose origins date back to the early twentieth century.

Following the merger, the company focused on integrating operations and strengthening its position as a major defense contractor for the U.S. government.

During the late 1990s and early 2000s, Northrop Grumman expanded through strategic acquisitions, including Westinghouse Electronic Systems (1996), Litton Industries (2001) and TRW Inc. (2002). These transactions significantly expanded the company’s capabilities in defense electronics, naval systems, satellites and space technologies.

Among its notable aerospace developments is the B-2 Spirit stealth bomber, one of the most advanced long-range aircraft used by the U.S. Air Force.

In recent years, the company has expanded its focus on space systems, next-generation defense technologies and cybersecurity, including the development of the B-21 Raider strategic bomber and investments in artificial intelligence and advanced sensor systems.
