Our organization’s history goes well beyond the companies founded by Jack Northrop and Leroy Grumman. Today’s Northrop Grumman is a result of the integration of over 20 pioneering companies from across the aerospace, technology and defense industries, each with their own unique history of Defining Possible.
From Teledyne Ryan’s Spirit of St. Louis and Grumman’s Lunar Module to Westinghouse’s first radars and Scaled Composites’ groundbreaking SpaceShipOne, these heritage companies have achieved countless historic milestones. We’re honored to carry on their legacies as we pioneer a new path forward.
