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.

On Feb. 1, 2020, Amentum was born out of the federal business of 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. 

In November 2020, we acquired DynCorp International, a provider of sophisticated aviation, logistics, training, intelligence and operational solutions. By joining forces, we deliver enhanced capabilities including a full suite of logistics/aviation services and solutions to support critical needs anywhere, anytime.
