What Our Name Means

The word Amentum is derived from a Greek word used to describe the leather device that was attached to a javelin to increase its range and the stability in flight. The device allowed the javelin to land on target with precision.

We communicate confidence and stability to our customers through a strong commitment to excellence in all that we do. Moreover, the name also sounds like momentum, which connotes our forward-leaning approach and innovation-driven future in support of our customers’ missions. The name Amentum serves as a beacon for sharing our continued story of success, experience, and our people’s resilience and dedication to the mission.
