Our history goes beyond the companies founded by Jack Northrop and Leroy Grumman.

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.
