Corporate Lineage

Corporate Lineage

Although Amentum is new, our heritage dates back to the early 20th Century, with roots in iconic American companies. We honed our reputation throughout the Golden Age of Innovation, establishing deep relationships with customers in the U.S. Department of Defense and Department of Energy.

In more recent years, we became a preeminent government contractor as URS and later joined with the world’s premier integrated infrastructure company, AECOM. We honed our values of operational excellence, mission focus, and successful execution underpinned by a strong sense of safety and integrity.

On Feb. 1, 2020, Amentum was born. Preserving our culture of excellence and commitment to safety and ethical business, Amentum remains a trusted partner to U.S. federal government agencies, allied governments and corporations worldwide supporting critical programs of national significance across defense, security, intelligence, energy, and environment. Headquartered in Germantown, Md., we are more than 20,000 professionals in 48 states and 28 foreign countries and territories working together to ensure the success of our customers’ most vital missions.
