The foundation of Northrop Grumman is built on a multitude of companies coming together over the past 90 years. These companies each brought their own legacies.
With the launch of our new brand in 2020, it is more important than ever to celebrate our diverse heritage. The graphic representation of our foundational companies and their logos help to tell our story and showcase the pioneering nature of our company.
It should be noted that, while comprehensive, the graph is not complete. Some timelines are simplified for easier viewing (and because of space constraints), especially before 1994 when Northrop and Grumman came together. Not all the permutations in the history of Vought, Orbital ATK, Grumman, Litton, Northrop or Westinghouse are listed. Nor are all the mergers and acquisitions or sell-offs and spin-offs recorded.
